Abstract: 978,785. Tunnel diode logic circuits; keying carrier frequencies. SONY CORPORATION. Jan. 2, 1962 [Jan. 18, 1961], No. 144/62. Headings H3R and H3T. A NOT circuit comprises an astable tunnel diode oscillator arranged to be synchronized by oscillating input signals, the input and output of the oscillator being coupled to an amplifier in antiphase so that no output is obtained from the amplifier during the presence of input signals but an oscillating signal output is obtained in the absence of the said input signals. As shown in Fig. 1, the circuit comprising tunnel diode 3 is arranged to be inoperative except during the presence of oscillatory signals at terminal 1 when tunnel diode 3 and the coil 4 oscillate in synchronism with the input signal. Signals from tunnel diode 3 are fed via a diode 16 to synchronize an astable oscillator 10 comprising a tunnel diode 11. The outputs of circuits 2, 10 are coupled via diodes 21, 26 and a centre-tapped transformer 18 to a tunnel diode amplifier 28 in such a way that signals from oscillator 10 only appear at output terminal 29 in the absence of input signals at terminal 1. The oscillators 2, 10 preferably operate at 3 mc/s. The tunnel diodes 3, 11, 27 may be formed from silicon, germanium or gallium-arsenide. The coupling diodes 8, 16, 21, 26 may be backward diodes or gold-bonded diodes. In Fig. 4 the oscillating circuits 4, 12 are inductively coupled via diodes 34, 35 in anti-phase to the tunnel diode amplifier 28.

Abstract: 1,244,472. Controlling clutches. AMPEX CORP. 25 March, 1970 [2 June, 1969], No. 14465/70. Heading F2L. [Also in Divisions G4-G6] In a device for reversing the order of magnetic heads 56, 57, 63 in a bidirectional tape recorder (see Division G5) by rotating a head support disc 61 through 180 degrees whenever a drive motor 31 is reversed, a clutch member 81 is continuously belt-driven 83, 87 by the motor and is coupled to a cam disc 108 to rotate the latter once by engagement of a spring-loaded detent 107, slidable in a groove 111 in the disc 108, with teeth 117 of the clutch 81. When the clutch 81 reverses, it causes a driven plate 89 with a felt disc to rotate and thereby a V-shaped slot 96 to move a pin 94 outwards allowing a shoulder 103 to free the detent 107, then inwards, so that when the detent has made one revolution it re-engages the shoulder 103 to retract the detent 107, the disc 108 being located by a second detent 121. The cam disc 108 retracts the head disc 61 axially so as to be engaged and rotated by the belt 83 driving the clutch 81.

Title: Improvements in the catalytic production of hydrocarbons from oxides of carbon and hydrogen
IPC: C07C1/02
Filed: 1927-05-30
Abstract: 279,347. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). May 30, 1927. Hydrocarbons.-In the catalytic production of methane and other hydrocarbons from oxides of carbon and hydrogen, or gases which split off hydrogen, the attainment of too high a temperature is prevented, and the heat of reaction is utilized, by connecting the contact chamber with a generator of highpressure steam in such a way that an exchange of heat is effected between them. For example, the catalyst may be arranged in tubes mounted in a high-pressure boiler, or tubular steam generators may be arranged in the contact chamber, or the steam generator and the catalyst tubes mav be arranged in a bath of fused metal. Preferably, the steam is produced at or slightly below the pressure corresponding to the desired temperature of reaction. In the construction shown, a number of tubes A containing the catalyst are arranged within a boiler in which steam is generated at a pressure of 17 atmospheres. The reacting gases are admitted at B and leave at C, and the generated steam is led off at D. A gauge glass E, a connection F to a safety valve, and an inlet G for water are provided, the inlet G serving also to admit superheated steam or hot gases in order to start the reaction.

Abstract: 1287203 Triggering time bases SOLARTRON ELECTRONIC GROUP Ltd 19 April 1971 [25 March 1970] 14625/70 Heading H3P A second time base is triggered after a first time base from a common source of triggering pulses by opening a path to the second time base for trigger pulses when the first time base reaches a given level, as shown, when a trigger pulse at 10 reaches a level determined by 14 a trigger pulse train is provided by 12. A pulse from the train changes over bi-stable circuit A to initiate a ramp which resets the bi-stable at the end of the trace by means of 21. The ramp is fed to a comparator 28 together with a reference voltage 29 so that a pulse is produced when the ramp reaches the reference level. The comparator output pulse enables an and gate so that a subsequent pulse from the trigger train operates a second time base 20, 16, 22 similar to the first. The reset of bi-stable 20 produces a pulse in a pulse former 55 to reset the first time base if this has not been effected. Also, the end of both sweeps reopens triggering gate 25 after a reset delay provided by 24. To allow the time bases to trigger at different points in the trigger pulse waveforms the output of bi-stable circuit A is fed back to the trigger pulse generator or to the trigger level circuit to charge effectively the trigger threshold.

Title: Improvements in and relating to the control of steam generators of the flash type
IPC: F22B35/00
Filed: 1942-10-28
Abstract: 568,722. Automatic control systems. LEWIS, M. H. Oct. 28. 1942. No. 15128. [Class 38 (iv)] [Also in Group XIII Flash-type steam generators are controlled by thermosensitive devices, one, external to the boiler, subjected only to the heat of the steam supplied, controlling the injection of an amount of feedwater, not exceeding 5 per cent of the maximum evaporation of the boiler, into the steam tube sufficiently in advance of the thermo-sensitive device to ensure its vaporization before it reaches the thermo-sensitive device, and a second, within the boiler, controlling the flow. In the example shown, the thermostat 16, in a loop of the steam supply pipe 15, allows contacts 34 to close on undue rise in temperature, whereby a circuit is made through an electromagnetically-operated valve 31 to allow feedwater to pass from the pump to the boiler, a proportion of which is injected through pipe 37 and control tube 38 into a pipe 12 connecting the generator section 11 of the boiler and the superheated section 14. A second thermostat 17 in a loop of the steam delivery pipe in the hottest part of the fire-box, controls contacts 27 to break the circuit of the motor 4 driving the fan 3 of the furnace through a relay 22, 18, A third thermostat 13 controlled by the temperature of the steam in the pipe 12 causes the feedwater valve 31 to open to the boiler if the temperature rises unduly, by closing contacts 35. A pressure-operated diaphragm 26 opens contacts 24, or, at a later stage, contacts 25, according to the position of a two-way switch 23 to break the circuit to the draught-motor on the steam pressure in pipe 12 rising to the desired of two predetermined maxima,. In a modification, the thermostats are of the bulb type and operate Bourdontube dials with contacts on the indicating needles and lamps are provided to show when feedwater is being supplied to the boiler and when the fan is out of action. In this modification, separate thermostats govern the injection water and the main feed and control of fire is not by temperature of the hottest part of boiler, but by that of the upper part of the water tubes.
