Vintage fabric sample book finds modern home
Vintage fabric sample book finds modern home

Margo Krager discovered an unusual source for her fabric retail/consulting business — an antique fabric sample book. It is called the Dargate book and it all started with a surprising phone call in 1997.
Krager is a textile historian and owner of ReproductionFabrics.com, an online fabric retailer. In addition to providing reproductions of period fabrics to costumers and quilters; she also works with Windam Fabrics to bring reproduction fabrics to the marketplace. Many reproduction designs are based on fabrics found in old quilts and garments at museums or private collections. For Krager, that changed with finding the Dargate Book.

She calls it the Dargate Book because of the way she acquired it. One busy Monday morning, she received a phone call from Dan Zibco, a plastics manufacturer in Cleveland, Ohio, that struck at the very center of her passion for reproduction fabrics. “Would she be interested in buying a book of old fabric samples?”

Zibco had purchased an auction lot of antique furniture from the Dargate Auction House in Pittsburgh. Buried in the lot of goods was a slipcase containing a fabric sample book. Not interested in antique books (or fabric), Zibco consigned it to an antique book dealer to no avail. Anxious to recoup some of his investment in the auction lot, he also searched the Internet for a possible buyer and found Krager.

A book dealer who had looked at the piece dated it to the early 1800s, but the slip case had been added later.

The ledger-sized book contained more than 2,100 vintage, cotton fabric swatches from almost 175 years ago. http://www.texflagsample.com/en/About.aspx

Current transformer
Current transformer

In electrical engineering, a current transformer (CT) is used for measurement of electric currents. Current transformers, together with voltage transformers (VT) (potential transformers (PT)), are known as instrument transformers. When current in a circuit is too high to directly apply to measuring instruments, a current transformer produces a reduced current accurately proportional to the current in the circuit, which can be conveniently connected to measuring and recording instruments. A current transformer also isolates the measuring instruments from what may be very high voltage in the monitored circuit. Current transformers are commonly used in metering and protective relays in the electrical power industry.

Like any other transformer, a current transformer has a primary winding, a magnetic core, and a secondary winding. The alternating current flowing in the primary produces a magnetic field in the core, which then induces a current in the secondary winding circuit. A primary objective of current transformer design is to ensure that the primary and secondary circuits are efficiently coupled, so that the secondary current bears an accurate relationship to the primary current.

The most common design of CT consists of a length of wire wrapped many times around a silicon steel ring passed over the circuit being measured. The CT s primary circuit therefore consists of a single turn of conductor, with a secondary of many tens or hundreds of turns. The primary winding may be a permanent part of the current transformer, with a heavy copper bar to carry current through the magnetic core. Window-type current transformers are also common, which can have circuit cables run through the middle of an opening in the core to provide a single-turn primary winding. When conductors passing through a CT are not centered in the circular (or oval) opening, slight inaccuracies may occur.

Shapes and sizes can vary depending on the end user or switchgear manufacturer. Typical examples of low voltage single ratio metering current transformers are either ring type or plastic moulded case. High-voltage current transformers are mounted on porcelain bushings to insulate them from ground. Some CT configurations slip around the bushing of a high-voltage transformer or circuit breaker, which automatically centers the conductor inside the CT window.

The primary circuit is largely unaffected by the insertion of the CT. The rated secondary current is commonly standardized at 1 or 5 amperes. For example, a 4000:5 CT would provide an output current of 5 amperes when the primary was passing 4000 amperes. The secondary winding can be single ratio or multi ratio, with five taps being common for multi ratio CTs. The load, or burden, of the CT should be of low resistance. If the voltage time integral area is higher than the core s design rating, the core goes into saturation towards the end of each cycle, distorting the waveform and affecting accuracy.

Current transformers are used extensively for measuring current and monitoring the operation of the power grid. Along with voltage leads, revenue-grade CTs drive the electrical utility s watt-hour meter on virtually every building with three-phase service and single-phase services greater than 200 amps.

The CT is typically described by its current ratio from primary to secondary. Often, multiple CTs are installed as a "stack" for various uses. For example, protection devices and revenue metering may use separate CTs to provide isolation between metering and protection circuits, and allows current transformers with different characteristics (accuracy, overload performance) to be used for the devices. http://www.jyins.com/productshow/LMZ3-0-66_id164.html

Apple Portables: Troubleshooting MagSafe adapters
Apple Portables: Troubleshooting MagSafe adapters

The LED on the adapter connector doesn t light up when attached to the computer.

The adapter only charges the computer intermittently.

The adapter s white insulation separates from the magnetic end of the MagSafe connector.

If you are attempting to troubleshoot a non-MagSafe power adapter with a barrel-type connector, refer to Apple Portables: Troubleshooting power adapters with a barrel-type connector.

If you receive a replacement MagSafe adapter with a "L" style MagSafe connector when you previously had a "T" Style MagSafe connector, the "L" style adapter is fully compatible with your Apple computer.

Resolution

Follow these steps to identify the cause of the issue and find out which solutions may be available to you.

If you see a spark

Sometimes when you plug the power adapter into the wall, you may see a spark. This is usually normal and can occur when you plug any electrical appliance into a live outlet. If the spark comes from somewhere other than the blades of the plug, if you experience any damage or discoloration of the adapter, or if you have other concerns about sparking, contact Apple.

Troubleshooting power adapter issues

Collapse All Sections | Expand All Sections

Make sure a known good outlet is being used.

Verify that the power outlet you re using is working correctly. Plug in a known good appliance, such as a lamp, TV, or clock, and confirm it powers on properly.

Make sure the proper wattage adapter for your portable computer is used.

Select the appropriate power adapter for your Apple portable computer. You can use a higher wattage power adapter, but you cannot use one with less wattage without potential operating issues.

Identify line noise issues.

Unplug the power adapter from the wall, let it sit for 60 seconds, then plug the adapter back in.

If the adapter works after this 60-second "rest", you most likely have a line noise issue with your power source. You should reset the adapter periodically by repeating this moment of rest. This issue occurs when the AC adapter s "over voltage protection" feature senses ground noise and then turns off the adapter.

Some possible sources of line noise include lights with ballasts, refrigerators, or mini-refrigerators that are on the same electrical circuit as your computer. This behavior may not occur if you plug the power adapter into an uninterruptible power supply (UPS) or plug it into a different circuit.

Unless the adapter continues to exhibit this behavior on a known good outlet, it does not need to be replaced.

Be sure you are using the adapter in a well ventilated area

The power adapter may become very warm during normal use. Always put the power adapter directly into a power outlet or place it on the floor in a well-ventilated location. If you are using your MagSafe adapter in a poorly ventilated area, or if the MagSafe adapter is covered by a blanket or other form of insulation, it may turn itself off in order to prevent damage to the adapter.

You may notice the following:

Your power adapter may not charge the computer.

The LED on the adapter connector may not light up when attached to the computer.

The adapter may only charge the computer intermittently.

If you encounter these behaviors please disconnect the adapter and wait until it cools down. Once cool, the adapter should function normally. If you still have issues, follow the rest of the troubleshooting in this article; beyond that please contact Apple.

Check for possible AC plug (also known as a "duck head") or two- or three-pronged AC cord issues.

If you re using the AC plug (also known as a "duck head") with the power adapter, swap it out for the included two- or three-pronged AC cord, or if you are using the two- or three-pronged AC cord swap it out with the AC plug. Either connector can be easily connected the adapter as shown below. http://www.jyins.com/

Operation principle and circuit system of switching power supply
Operation principle and circuit system of switching power supply

Rectifying bridge: To rectify AC current to one direction

- Electrolytic capacitor: To build up electricity and work to keep voltage

- High frequency transformer: To transfer energy from primary to secondary

- Control circuit: To control ON/OFF timing of switching device to stabilize secondary voltage

In this system, input (alternate current: AC) is converted to output (direct current: DC). Input side is called "Primary output side is called "Secondary" to which energy is transferred via high frequency transformer.

(1) Connect alternate current (AC) to switching power supply.

(2) The AC is rectified by rectifying bridge and smoothed by primary electrolytic capacitor after that.

(3) Switching operation (repeated electric ON/OF operation) of switching device generates alternate current with high frequency.

(4) Energy (AC) is transferred via high frequency transformer to secondary side.

(5) Rectified by secondary diode and smoothed by secondary electrolytic capacitor, the energy is converted to DC (direct current) as output.

(6) To keep output voltage stabilized, switching is controlled through feedback system.

That is the basic operation principle of switching power supply.

Circuit method

Circuit method in switching power supply depends on "DC-DC converter s mode which converts DC to AC with high frequency, and again convert it back to DC." Also, in determining switching cycle of DC-DC converter, it is classified into two modes. One is called self-excitation mode whose switching block determines the switching cycle on its own. The other is called separate excitation mode (PWM mode) that has an oscillator to decide the frequency independently. Self-excitation mode s features are "Cost is low due to simple circuit structure," and "the frequency changes according to input voltage and load condition." Separate excitation mode s features are "Cost is generally high compared to self-excitation mode as it uses ICs," and "the frequency is constant." Also, there are another two modes when energy is transferred from primary to secondary. One is called forward mode where the energy is transferred during ON period, and the other is called flyback mode where the energy is transferred during OFF period.

(1) Single forward

This mode is used in many switching power supplies due to simple structure and stable control. (Adopted in our Nonstop power supplies in many cases). Separate excitation mode is mostly used from small power to high power as well. Disadvantage is poor usability of transformer.

(2) Flyback (called RCC)

This mode need a few components and is the simplest mode, but not suitable to high power. This is mostly adopted to small power, but input voltage range is wide.

(3) Push-pull

This mode uses two switching devices and coils to turn on alternately. Bias magnetism of transformer is critical.

(4) Half-bridge

Operation is the same as push-pull mode, but as the applied to transform is half of Vi, low voltage transistors can be used. The usability of transformer is better, but the temperature rise of each capacitor caused by switching current that flows in capacitors is critical.

(5) Full-bridge

Circuit structure is complicated, but low voltage switching devices can be used. It gives high efficiency and is adopted to high power. Usability of transformer is the highest of all. Critical points are bias magnetism and penetration current between upper and lower devices (FETs).

(6) MagAmp (Magnetic amplifier)

This mode is to control phase in pulse utilizing magnetic saturation of amorphous core which has rectangular hysteresis property to stabilize output voltage.

(7) Step-down chopper

This mode is non-insulated type to convert to low voltage without transformer.

(8) Step-up chopper (also called flyback)

This mode is non-insulated type to convert to high voltage without transformer. http://www.jyins.com/switching-power-supply.html

How to Convert Sunlight Into DC Electricity
How to Convert Sunlight Into DC Electricity

In the era of rapidly disappearing fossil fuel resources, and, as technology advances, renewable energy sources are becoming increasingly accessible to the public. Converting sunlight into electrical power is a relatively simple task and can be accomplished on any scale, be it a solar-powered R/C car or a large outdoors solar array. With the use of a small monocrystalline solar panel and a few simple electrical regulation components, sunlight can be converted into usable DC energy for small devices such as R/C cars, emergency radios and electric lights.

Instructions

1

Install the solar panel or panels of your choice by bolting it to a mount of some sort. Install the panel in a location where it is likely to get the most sunlight. Outdoor panels can be set on fixed mounts, adjustable mounts and specialized tracking mounts that follow the angle of the sun. Smaller panels can often be bolted directly onto another surface; for example, if the panel is meant to power a remote control car, it should be screwed to the top of the car s frame.

2

Run the output cable from the solar panel to the input jack or terminal on the charge controller or dc meter, and connect it with a plug (or by soldering, if it is not the plug type). These devices monitor the amount of electricity flowing into the batteries and allow the batteries to dispense power when the solar panel is not producing electricity. This is important because without regulation, the battery may be damaged by overcharging or overdraining.

Wire the charge controller or dc meter to the battery array by connecting the positive terminal to the positive terminal of the first battery and the negative terminal to the corresponding terminal of the last battery --- the batteries are then wired together by connecting the positive terminal of each battery to the negative terminal of the battery before it. The array may also be wired in parallel, meaning the positive and negative terminals of the charge controller will be wired to the corresponding terminals on the first battery, and each additional battery will have its positive and negative terminals wired to the same-charge terminals on the battery before it.

4

Wire the DC outlet to the batteries and charge controller in accordance with the instructions provided with the equipment --- usually this will entail wiring the outlet to the charge controller s output jack or cable. Place the DC outlet in the area that it will be used; the charge controller can control the voltage of output, and any needed DC power can be accessed from the outlet. http://www.jyins.com/
