Allen-Bradley Resistors Advertisement
Here is the text of the advertisement: Stop Interference on Radio-Equipped Cars With Bradley Suppressors No Shielded Ignition Cable Needed Bradley Suppressors are special solid molded resistors used by prominent car manufacturers to provide individual resistors for each spark plug and for the common cable to the distributor on radio-equipped can. They increase the resistance of the high tension ignition system and minimize the disturbing oscillations in the ignition circuit which interfere with the radio receiver in the car. When used with suitable bypass condensers in other parts of the circuit, shielded ignition cables are unnecessary. They do not affect the operation of the motor. The sturdy construction of Bradley Suppressors adapts them for the severe service in which they are used. Heat and moisture and age have no effect upon their performance. They are the last word for motorcar radio. The Bradleyometer is a potentiometer with approximately fifty solid resistance discs interleaved between metal discs. Bradleyunits are solid molded resistors unaffected by temperature, moisture or age. Their accurate calibration, great mechanical strength and performance make them ideal for providing correct C -bias, plate voltage, screen grid voltage and for use as grid-leaks and as fixed resistors in resistance-coupled circuits. All units are color-coded to meet any radio set manufacturer's specifications. The total number of discs can be arranged in accordance with any resistance-rotation curve. One or more Bradleyometers can be arranged to operate with one knob. Mixer controls, T-pad and H-pad attenuators and other complex controls can be provided. ALLEN - BRADLEY CO. 106 W.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived... All trademarks, copyrights, patents, and other rights of ownership to images and text used on the RF Cafe website are hereby acknowledged. My Hobby Website: AirplanesAndRockets.com
