Title: Improvements in or relating to apparatus arranged to be responsive to mechanical impulses such as discharge counters for automatic firearms
IPC: F41A19/01
Filed: 1942-08-14
Abstract: 560,321. Counting apparatus. K.D.G. INSTRUMENTS, Ltd., and PURNELL, J. E. Aug. 14, 1942, No. 11440. [Class 106 (i)] [Also in Group XXI] An apparatus responsive to reciprocating impulses set up in a mechanism, such as an automatic firearm, is associated with a counting device and comprises a support against which is urged a movable mass, the latter being positively moved by the support in one direction but lagging behind it, due to its inertia, in the other direction, the relative motion thus occurring being employed to actuate the counting device. In the construction shown, the apparatus is fitted to the wing spar 11 of an aircraft, and the impulses are imparted to it by an abutment 14 on the barrel 10 of a cannon when the latter returns to its firing position after recoil, under the action of the return spring 12. The apparatus comprises a casing 15 closed at one end by a fixing plate 16 and at the other by a block 17 of insulating material. The casing houses a spring-controlled weight 22, the spring 24 of which abuts against a plate 25 secured to one terminal 18 of two terminals 18, 19 mounted in the block 17. The other terminal 19 has a projecting stem 27 which, when the weight is moved against the action of its spring, contacts a spring-controlled pin 28 mounted in the weight 22, thus providing a connection between the two terminals via plate 25, spring 24, weight 22, pin 28, and stem 27. The closing of circuit in this manner operates the counter 4 which registers the. amount of ammunition remaining in the magazine.

Title: Improvements in fluid-pressure responsive electric switches
IPC: H01H35/40
Filed: 1940-07-11
Abstract: 540,471. Fluid-actuation of switches. VICKERS, Inc. July 11, 1940, No. 11533. Convention date, July 13, 1939. '[Class 38 (v)] A fluid pressure actuated switch which is independent of momentary pressure-rises and is adaptable to a wide range of operating pressures, comprises a snap-action switch 38 operated by a plunger 42 against the action of a retractive spring 44, and spaced at 52 from the stud 50 within a piston 18 which is upwardlybiassed by spring 48 and works in a seal 16 at the lower end. Annular grooves 20, 22 on the piston are interconnected by a flat 28 on the cylindrical surfaces, and one or more notches 26 are provided on the flange 24, so that restricted communication is obtained between the upper piston-face and the restricted aperture 34 of a bushing 32 leading to a sump. The upper piston-face communicates over passages 72 and 62 with a further bushing 58 with a relativelylarge aperture 60 connected to the pressuresource, the passage 62 being normally closed by a ball-valve 66 the spring. 68 of which is adjustable by a member 70. When the valve 66 opens and provided the pressure is enough for the rate of supply of fluid to the piston-face to exceed the rate of escape through aperture 34, the piston is depressed and after taking up the clearance 52 and the movement of the snapspring, operates the switch-contact. In the reverse movement, the fluid escapes to the sump. Both bushings 32, 58 are replaceable and by providing a range of bushings of different sizes of aperture, a range of operating pressures and speeds can be accommodated. The Specification refers, however, to an aperture 34 of negligible resistance in which case the passage 28 is relied on to provide the resistance. In a modification, Fig 3 (not shown), passage 62 communicates with the bushing 58 by a further passage which is normally held closed by a light spring but opens when the pressure at the bushing 58 falls sufficiently. The passage 28 is dispensed with and aperture 34 is enlarged and deals only with seepage past the piston, the clearance 52 providing the immunity from operation by momentary pressure-rises. The aperture in bushing 58 may be as small as may be desired.

Title: Improvements in or relating to systems of receiving and indirectly amplifying radio frequency electrical oscillatory energy
IPC: H03F3/48
Filed: 1924-05-09
Abstract: 215,785. Jackson, W. J. Mellersh-, (Westinghouse Electric & Manufacturing Co.). May 9, 1924. Thermionic heterodyne receivers; undesired signals, eliminating. - Relates to the system of heterodyne reception described in Specification 137,271, in which incoming waves are combined with local oscillations to produce beats of lower radio-frequency; and consists in causing the beat currents to react on the input cir. cuits to obtain further amplification. The beat frequency is the resultant of the incoming frequency and an harmonic of the locally-produced frequency, as described in Specification 224,817. As shown in Fig. 1, the received oscillations are applied to a tuned circuit 4, 5 connected in the grid circuit of an amplifier 6, and the amplified oscillations are transferred by a coupling 11, 12 to the grid circuit of the local oscillator 16. The oscillator plate circuit is back-coupled by a coil 13 to a tuned grid circuit 14, 15, the frequency of which is so adjusted that one of its harmonics differs from the received frequency by a readily-amplifiable low radiofrequency. An oscillatory circuit 9, 10 tuned to this intermediate frequency is connected in the plate circuit of the valve 16 and coupled to a similarly-tuned circuit 7, 8 connected in the grid circuit of the valve 6. The intermediate-frequency currents are thus amplified by the valve 6 and are transferred through the couplings 18, 19 to the grid circuit of the detector 20, which has the telephones 21 in its plate circuit. The intermediate-frequency oscillations also react through the coupling 11, 12 on the oscillator 16, and thus increase the efficiency of the frequency conversion. The coupling between coils 8, 9 is adjustable both as regards degree and polarity, the polarity required being the opposite to that required for ordinary reaction. The coil 14 should preferably be connected between the coil 12 and the filament. Additional stages of amplification may be inserted between the coil 18 and the detector; and the process of frequency conversion may be repeated. In the modification shown in Fig. 3, a loop aerial 33 is connected through a high-pass filter 40, of one or more stages, to the grid of the first valve 41, and the beat-frequency currents are applied in the grid circuit of this vaLve by a coupling 35, 30, the secondary coil 30 being connected directly between grid and filament and tuned by a condenser 32 between the grid and the filter or aerial. The filter reduces interference by waves approximating in frequency to the intermediate or beat frequency.
