Title: Improvements in electrical systems for the transmission and reception of intelligence
IPC: H03K7/08
Filed: 1940-11-05
Abstract: 544,975. Transmission systems. STANDARD TELEPHONES & CABLES, Ltd., and BEATTY, W. A. Nov. 5, 1940, No. 16089. [Class 40 (iv)] [Also in Group XL] In a combined transmitter and receiver of sound and other signal waves in the form of a succession of pulses of constant amplitude and of duration variable in accordance with the instantaneous wave amplitude, one or more valves, e.g. V5, used as amplitude limiters in the production of pulses for transmission have their operating conditions changed when the apparatus is switched over to reception. In the arrangement shown with switches 12, 22, 23. 24, 25, 34 in the transmitting position T, microphone output is amplified by valve V3 and applied to the control grid of valve V4 which also receives a sinusoidal wave of the pulse frequency from oscillator V6. The control grid has a normal excessive negative bias and has a low anode potential derived from potentiometer 18, 19, so that it has a low saturation point, with the result that the output comprises negative pulses of the oscillator frequency varied in width in accordance with sound amplitude. These pulses are amplified by valve V5 from which the negative bias has been removed by switch 25 so that the valve acts as a limiter with maximum amplification. The output of V5 in the form of positive pulses is applied to a back-biassed radio frequency oscillator V2 tuned by a circuit comprising a copper trough 27 and insulated rod or tube 28 connected by fixed and variable condensers 29. 30. The antenna is .tapped to a suitable point on 28. When the switches are changed over to the receiving position R, the detector VI is coupled to amplifier V3 the output of which is fed directly to V5, valve V4 being bye-passed to avoid complicated switching. The tuned receiving circuit of V1 is similar to the tuned circuit of V2 except that rod 38 projects through the trough 36 for coupling to the antenna. Valve V1 acts as an anode bend detector. The short circuit on the grid bias resistance of V5 is removed so that this valve operates as a normal amplifier. The specification states that the invention may be applied to pulse transmission systems of the double pulse type in which short pulses mark the times of commencement and termination of the variable intervals, limiter stages in the transmitting arrangement being used in the receiving stage to produce solid pulses from the marking pulses.

IPC: F01B1/06
Filed: 1934-06-04
Abstract: 438,971. Compressed -air -operated vehicles. JENKINS, F. A. E., Reading Road, Brighton-le-Sands, New South Wales, Australia. June 4, 1934, No. 16575. [Classes 8 (i) and 8 (ii)] [See also Groups XXVI and XXXI] A compressed - air - operated vehicle comprises an air receiver 20, an internal - combustion engine-compressor unit 24, 25 and air engines 39 coupled to the road wheels. The compressor engine is automatically controlled by the receiver pressure and is started by high pressure air stored in a smaller receiver or starting tank 22 which is charged by an air engine-compressor unit 33 operated by air from the main receiver 20. For starting a lever 102, Fig. 15, is depressed to open a valve 100 which supplies high pressure air from the starting tank 22 to start the engine in a known manner. When the pressure in the receiver has reached the maximum allowable value the pressure on a spring loaded diaphragm 119, Fig. 17, operates a rod 117 which closes the engine fuel valve and stops the engine unit. The engine is automatically restarted when the pressure falls below a desired minimum by means of a diaphragm 107, Fig. 15, operating the starting lever 102 to open the starting valve 100, the engine fuel valve being opened at the same time by the diaphragm 119. When the pressure in the starting tank 22 falls a further diaphragm 132<1>, Fig. 16, opens a valve 126 to supply air from the main receiver 20 through a pipe 34 to drive the air engine-compressor unit 33, which valve closes when the desired pressure has been restored. A further electricallyoperated pump is provided for initially charging the starting tank. The air engines 39 coupled to the road wheels are of the radial cylinder type the admission and exhaust of the air being controlled by a rotary distributing valve 79, Fig. 5, 49 being the air supply pipe, 54 the exhaust pipe and 84, 84<2> the pipes to the cylinders.
