Patent GB-1091636-A (GB)
Title: A snap-action trigger circuit including a controlled rectifier switching device
IPC: H03K17/725
Filed: 1965-04-12
Abstract: 1,091,636. Switching circuits. GENERAL ELECTRIC CO. April 12, 1965 [May 18, 1964], No. 15394/65. Heading H3T. [Also in Division H2] A semi-conductor controlled rectifier is turned on only near the start of the rising part of a rectified A.C. waveform by means of a timing capacitor charged through a temperature-sensing element, so that a more precise switching action is obtained This principle is applied in Fig. 1 to the control by a thyristor of a protecting relay 13 for switching off an electric motor if the temperature sensed by a thermistor T 1  is too high. The A.C. supply 11, 12 is rectified by a diode bridge network D 1 -D 4  and used to charge up a capacitor C 1  through a resistor R 5 . If the capacitor voltage is sufficient to cause a unijunction transistor Q 1  to conduct, the capacitor discharges through R 1  and the resulting voltage pulse fires the thyristor SCR 1 . This operation occurs once per half-cycle and the resulting current is sufficient to keep the relay 13 energized. If the temperature rises above a certain point, the resistance of T 1  will fall, thus reducing the voltage on C 1  to a point where the unijunction transistor does not conduct. The thyristor is then not fired and the relay falls off. Zener diode Z 1  limits the peaks of the waveform so that C 2  charges only during the rising part of each half-cycle, giving a boost to the potential across C 1  and firing the unijunction at this point. Temperature compensation is provided by R 3 , and capacitor C 3  prevents false triggering by negative transients. If the temperatures at several points are to be sensed (Fig. 4, not shown), the various thermistors (with series resistors) are joined in parallel across the timing capacitor, and the rectifier bridge is replaced by separate diodes in series with each thermistor. Alternatively (Fig. 5, not shown), positive temperaturecoefficient thermistors are joined in series across the auxiliary CR circuit of Fig. 1, and a single diode is used in place of the rectifier bridge. In both these modifications the relay coil is shunted by a reversely-poled diode, and firing occurs only once per cycle of the applied A.C. voltage instead of once per half-cycle as in Fig. 1.

Abstract: 502,161. Spray carburetters. CLAUDEL, A. June 7, 1937, No. 15736. Void. Convention date. June 5, 1936. [Class 7 (iii)] This Specification, which does not admit of satisfactory abridgment, relates to a carburetter having a main nozzle 1 delivering fuel into a passage 14, to which compressed air is supplied, and which also receives an emulsion, formed by fuel from a submerged compensating jet 3 and air entering through a passage 9. A well 13 supplies idling mixture to a passage 11 opening adjacent the throttle valve 43. Hot air supplied through a tube 29 across the outlet of the passage 14 completely vaporizes the fuel therein and cold air is supplied through ports 36 controlled from the throttle valve 43 through a delay-action device. The throttle is also adjustably connected to an acceleration pump 23 delivering fuel through a nozzle 26 above the passage 14 and to a valve 16 controlling the air admitted to the passage 14. A supplementary fuel nozzle controlled by a valve 21 delivers fuel into the passage 14. Thermosensitive adjustments may be provided for the pump 23, the air valve 16 and a valve 7 controlling the passage 9, and the pump and supplementary fuel nozzle may supply a non-detonating or other different fuel. In a modification, the Venturi into which the fuel nozzle 1, Fig. 2, delivers is formed inside a rotary valve 40 controlling both air and mixture, the idling mixture is adjusted by a screw having a notched end and the accelerating pump comprises two pistons 23a, 23c, one, 23c; of which, at starting, forces fuel through the port 26 while the other, 23a, injects aerating air into it. As shown, the pump is linked to the throttle, but it may be actuated by the suction above the throttle. Water, anti-detonant or another fuel may be fed directly to the mixing chamber from a main supply through a nozzle controlled by a valve which is connected to the throttle valve through a dashpot cylinder and piston adapted to actuate the valve only on sudden movements of the throttle valve. When different fuels may be fed to the main nozzle, valves 4, 5, Fig. 10, controlling the respective fuel inlets 1, 2, are actuated by a lever 7 loosely pivoted between two arms provided with adjusting screws 9, 10, and operatively connected to the valves. Fig. 9 shows a device for closing the fuel valve 3 during overrunning of the engine, the suction above the throttle operating through a passage 13, 14 to draw down a piston 9 on the valve. On opening the throttle, a cam 19 thereon opens a valve 18 to admit air beneath the piston. An air passage 4 allows fuel to drain away from the fuel passage 10 containing the valve 3. In another modification, double outlets are used for the starting and idling devices.

Abstract: 515,521. Revolving barrel locks. STERNER, B. May 31, 1938, No. 16202. [Class 44] In revolving barrel mechanism having pushers displaceable longitudinally in the barrel against the action of springs by the bits of an adjustable key, and capable of being coupled to combination members displaceable longitudinally in a fixed portion of the mechanism, the pushers are U-shaped ; their internal branches 3 slide in a single keyway 9 having an uninterrupted wall; their external branches 12 have means to engage the combination members 6; and their crosspieces 11 slide in slots 19 provided in the barrel behind the keyway, so that the slots are always covered by the branches 3, 12 of the pushers between the uninterrupted wall of the keyway and the cross-pieces 11. When setting the lock to suit a new adjustment of the key, the members 6 are embraced by noses 13 on the pushers which are pressed to the front of the mechanism by spring 4. On inserting the key, the pushers are depressed, carrying with them the members 6. By turning the barrel in either direction, the pushers are disengaged from the members 6 and, at the same time, toothed segments 15, formed on the barrel between the pushers, engage grooves 16 in the members 6 to prevent accidental displacement. On withdrawing the key, the pushers return to the front of the mechanism and the noses 13 place themselves between the members 6 and prevent turning of the barrel. The branches 3 form together a polygonal prism completely filling the keyway and as they are longer than the slots 19, entry of a picking implement into the slots is prevented even when the pushers are fully depressed. To prevent picking by applying torque to the barrel and depressing the pushers until they are felt to engage the members 6, the latter have notches 18, Fig. 5, on their edges, asymmetrically disposed and equal in width to the noses 13.
