Title: Improvements relating to electronic switching or keying arrangements
IPC: H04L27/04
Filed: 1942-06-19
Abstract: 558,224. Valve circuits. STANDARD TELEPHONES & CABLES, Ltd., and MADDOCK, A. J. June 19, 1942, No. 8478. [Class 40 (v)] A keying arrangement for an amplifying system in which an auxiliary valve is used as the effective switch, is characterized in this that a grid of grids of a valve or valves in said amplifying system is or are normally biased from a first source to be effective and said auxiliary valve is controlled by low power keying voltages applied to the grid thereof, and the anode circuit thereof is used to apply directly to the grid or grids of said valve or valves in the amplifying system, an additional bias potential from a second source to render said valve or valves ineffective. Fig. 2 shows the invention applied to keying a pair of amplifiers V3, V4 in complementary fashion. With key S open, source B2<SP>1</SP> predominates over B2 to make the grid of V1 positive and grid of V2 negative. Thus source B1 is connected to the grid of V3 to block it while V4 has its normal bias and is conducting. Closure of key S leaves source B2 to supply negative bias to V1 and positive to V2 thus reversing conditions and giving a "mark " on V3 and a space on V4 with instantaneous change over. In Fig. 3 a gas discharge valve V5 is used for connecting the source B1 to the grid of V3 when the valve V5 is made conducting on moving key S to position a. This also charges condenser C which serves to extinguish V5 when V6 is made conducting by moving key S to position b. V6 is extinguished by valve V5 and condenser C when the key is moved back to a. This gives instantaneous changeover even though key S takes a finite time. This arrangement may also be used for the complementary keying of a pair of valves, Fig. 4 (not shown).

Title: Improvements in mechanism for operating lift gates
IPC: B66B13/24
Filed: 1953-03-03
Abstract: 737,125. Door-operating apparatus ETCHELLS CONGDON & MUIR, Ltd., and MARSDEN, J. March 30, 1954 [March 31, 1953], No. 8835/53. Class 65(1). In mechanism for power actuation of lift gates, in order to allow operation of the gate by hand in emergency, the power is transmitted through two levers A, B pivoted on a common pin 1, the levers being normally coupled together by means which allow the former lever to be moved independently of the latter if required. In the arrangement shown, the lever A has a stop A<SP>1</SP> through which it positively actuates the lever B in opening the door, and it also has pivoted to it at 2 a guidebar 4 and at 10 a rod 8 which slides in an aperture in a part 4b of the bar 4 and carries a spring 5 between the part 4b and nuts 9. The lever B has pivotally mounted on it at 6 a slide-block 7 engaging the guide-bar 4. Pressure on the lever B to open the gate independently of the power mechanism tends to rotate the guide-bar 4 to the dotted position and thus to compress the spring 5, which normally holds the two levers together; if the resistance of the spring is overcome, it finally assists the movement of the bar 4 to the dotted position, during which the slide-block 7 moves along the bar 4 as the lever B moves to the dotted (door open) position. A cam c rigid with the bar 4 actuates a switch C to cut off the power and/or to reset the mechanism when the lever B is moved independently of A.
