Title: Improvements in thermionic amplifiers for wide signal bands at intermediate frequencies
IPC: H03F1/50
Filed: 1937-08-24
Abstract: 479,421. Valve amplifying circuits. MICHAELIS, E. Aug. 24, 1937, No. 23176. Convention date, Aug. 28, 1936. Drawings to Specification. [Class 40 (v)] An intermediate frequency amplifier for television is arranged to accentuate the higher modulation frequencies by arranging that the oscillatory circuits are stagger tuned, in such a manner that one circuit is tuned to the frequency most to be preferred and that another circuit is tuned to a closely adjacent frequency and that the differences between the natural frequencies of the remaining coils is greater the further they are removed from the frequency to be preferred. The coils far removed from the frequency to be favoured are preferably provided with additional damping. The accentuation of the higher modulation frequencies may be sufficient to compensate for losses in the demodulator and in the cathode-ray tube.

A conductive plate coated with photoconductive material containing or coated with a natural or synthetic wax (see Division H1) is uniformly charged in the dark by corona discharge from a device maintained at 6000-7000 volts. The coating is then exposed behind a master or an episcopic or diascopic image of the master projected on it to produce an electrostatic image, which is developed by contact with a developer consisting of a carrier and toner charged to the same polarity as the image. Fine uncoated or resin coated glass balls, iron powder, starch or plastic balls, and crystals of sodium chloride, potassium chloride, sodium sulphate, anthracene, fluorene and indene are suitable carriers. The toner consists of pigmented resin or a mixture of resin and carbon black. A typical developer consists of 100 parts by weight fine glass balls and 2.5 parts of a toner obtained by melting together, grinding and screening to a particle size of 20-50 Á, 30 parts of polystyrene, 30 parts of maleinate resin, and 3 parts of carbon black. The image is fixed by infra-red heating or by treatment with ethyl alcohol, trichoroethylene, carbon tetrachloride or steam.
