Title: Improvements in multi-channel radio communication networks
IPC: H04J1/04
Filed: 1950-11-21
Abstract: 686,937. Radio transmitting systems; multiplex signalling. SOC. FHANCAISE RADDIOELECTRIQUE. Nov. 21, 1950 [Dec. 2, 1949], No. 28444/50. Drawings to Specification. Class 40 (v). A multi-channel radio communication system comprises a network of co-operating shortwave radio stations in which low frequency signals for transmission from each station are first transposed to a different frequency band for each channel of the system, then amplitude modulate intermediate frequency carriers different for each channel, one sideband of which is then suppressed and the intermediate frequency carrier reduced in amplitude, and finally the sum of all the frequency bands at each station amplitude modulates a single high frequency transmitter of the single sideband type. Further, for the frequency range, e.g. 15.5-23 Mc/s. of all the intermediate frequencies is made less than <SP>3</SP>/ 2 ; (2) all the intermediate frequency carriers are separated by selected unequal frequency intervals integral multiples of a basic frequency interval, so chosen that beat interference frequencies due to cross-modulation fall outside the channel-selecting intermediate frequency bands at the receivers of the system. The transmitted signals of a frequency of the order 300-400 Mc/s. may be the upper sidebands of a pair of local oscillators also used in reception and feeding the common aerial through tuned tank circuits. At the receiver local oscillators the same as or of the same frequencies as those used in transmission respectively frequency change an upper and a lower half of the incoming frequency spectrum down to the intermediate frequency band range, then narrow band intermediate frequency amplifiers in parallel separate the channels, the signals finally being detected by detectors individual to each channel and then transposed to their original low-frequency bands. The smallest and greatest intermediate frequency interval is shown to lie between p and pe(m- 2) times the selected basic frequency interval, where m is the number of channels and p is a number equal to or immediately above or this number increased by one. Specification 630,399 is referred to.

Abstract: 206,683. Marks, E. C. R., (Wayne Tank & Pump Co.). Oct. 24, 1922. Valves actuated automatically and intermittently for water-softening apparatus. A valve for supplying measured quantities of brine from a chamber D to a chamber C comprises a chamber E, fitted with a loosely fitting piston e<1> and a check valve e<5> which has a seating e<2>. When suction is created in the chamber C the valve e<5> rises, and as liquid in the port e<3> passes into the port e<4>, the piston e<1> rises until it seats on the port e<2>. When the suction ceases, the valve e<5> seats and the piston falls, liquid rising round it to flood the port e<3> ready for the next operation. A screwed rod e' limits the descent of the piston and its adjustment allows the quantity of fluid advanced at a time to be varied. The control valve H of the apparatus comprises a ring slug h<3> and a poppet slug h<2>, which co-operate with an apertured pin h<6> and a weighted piston h<9>. Fluid entering the chamber h forces the slugs h<2>, h<3> to rise and deliver fluid into the chamber h<8>, whereby the piston h<8> is raised, until the slug h<2> seats on the pin h<6>. As the water in the chamber h<8> empties gradually through the outlet h<13>, the piston falls and a spring h<17> passes on the pin h<6> until the slug h<2> is unseated and falls, water passing round it to take its place. When fluid again enters the chamber h the operation of the valve is repeated. Specification 208,576 is referred to.
