Title: Thermionic impulse amplifier
IPC: H04N5/073
Filed: 1944-05-10
Abstract: 582,744. Pulse amplifying circuits ; television. FARNSWORTH TELEVISION & RADIO CORPORATION. May 10, 1944, No. 8929. Convention date, March 18, 1943. [Classes 40 (iii) and 40 (v)] In a pulse amplifier or synchronizing separator circuit, a first valve is fed over an impedance from a storage device in the output circuit of a second valve, a control voltage for the second valve being developed across the impedance, an amplified pulse or synchronizing signal appearing in the output of the second valve. Valve 3, fed with anode current from a large condenser 15 over resistance 16, is supplied with negative pulses on the grid which reduce the anode current and allow valve 8 to conduct, producing amplified pulses across the integrating circuit comprising resistance 12 and condenser 15. Condenser 15, charged by the pulses through valve 8, maintains the anode current of valve 3 during the period between pulses, the potential difference across resistance 16 biassing valve 8 beyond cut-off. Condensers 7 and 10 decouple the screens of the valves to their cathodes. The input may be a television signal, the video component being of insufficient amplitude to cause valve 8 to conduct, the synchronizing signal alone being effective to produce a signal in the output.

Filed: 1944-05-18
Abstract: 585,722. Welding. WOODHOUSE & MITCHELL, Ltd., and FORBES, L. May 18, 1944, No. 9525. [Class 83 (iv)] In a flash - welding machine the movable head is fed forward during flashing or burning-off by hand through a worm gear and screw, the screw being connected to the piston of a cylinder of the movable head between which oil is forced under valve-controlled air pressure by a plunger to perform the upsetting operation when a cam-operated switch for regulating the desired amount of burning-off and the upset pressure is actuated. The head c which carries the movable clamping jaws b, bl contains a piston d<1> pressed forward by a spring d<2> and carrying a piston-rod d which is screwed at its rear end so that the whole head may be moved forward during burning-off by rotating a nut by handoperated worm gear e. The screw d is geared to a sleeve j' on which is mounted a cylinder j<5> provided with a calibrated ring j<9> locked in adjusted position by a nut j<6>. The cylinder carries a cam j<4> so as through lover j<3> to operate a switch when the desired amount of burning- off has been effected. After first setting the cam and after clamping the parts and setting a reducing valve h3 to give the desired upset pressure and a tapping switch m for determining the welding current, and then closing a switch s acting as an interlock for ensuring that cooling water is being circulated before the machine is operated, burning-off is started by operating the pedal switch p and the head c is then traversed by hand. Interlocking switches n, n<1> on the clamping gear prevent application of upset pressure until the work is clamped. When burning-off is completed, the switch j closes the contacts j<1> , j<2> which respectively bring into operation the current timing device k and the solenoid-operated valve h<4> for controlling the supply of compressed air to the plunger h which forces oil into the space g between the piston d<1> and the cylinder so as to apply upset pressure. When the welding is completed, the release of the work clamps opens the switches controlling the timing device and control valve h<4> so as to release the oil pressure from the space g. An exhaust port for compressed air is provided at h and a pipe i connects the cylinder h<1> with a reservoir il.

Abstract: 984,679. Analogue computers. HONEYWELL Inc. March 16, 1961 [March 24, 1960], No. 9691/61. Heading G4G. A computer predicts, in response to the input of an analogue signal representing the instantaneous rate of consumption of a commodity, the amount of that commodity, e.g. electrical energy, which will be used over a particular period. The input is applied at 6 and fed, across a resistance divider chain 7, 8, to an integrator 1 and to a potentiometer 10, the period of integration, which is equal to the time taken for the potentiometer slider to be driven via driver 10a automatically from the top to ground position, being controlled by a timer 13 set to the required time interval. The timer 13 operates a switch 5 to re-set the integration at the end of each time interval, and at the same time returns the potentiometer slider to the top position. The position of the slider at any time during its downward movement therefore represents the time remaining in the integration period. The output voltage from integrator 1 represents the total energy consumed since the start of the integration period and that from the potentiometer slider the energy to be consumed during the remainder of the period, (assuming a constant consumption rate for this remainder), so that the output of summing amplifier 11 corresponds to the energy to be utilized during the entire integration period. The predicted energy consumption can be recorded at 12 or compared with a desired consumption, an alarm 25 being set off when the predicted consumption exceeds the desired consumption (set in by a potentiometer 21).
