Title: Improvements in or relating to self-loading firearms
IPC: F41A3/64
Filed: 1942-07-20
Abstract: 561,016. Smallarms. AKTIEBOLAGET J. C: LJUNGMAN. July 20, 1942, No. 10113. Convention date, June 27, 1941. [Class 119] The rear end of the receiver 17 is closed by a vertically-removable plate 14 a' spigot 18 on which is received in a socket 20 in the casing 4. The plate is secured against removal by a vertical pin 24, the lower end of which has a cut-away flange 26, Fig. 5. The pin is rotatable through 180‹ by a finger-piece 32. The flange in the two extreme positions engages under a rib 29 in the trigger-plate 6 and so prevents withdrawal of the pin and of the closure-plate 14..In the extreme position shown, a cutaway part 30 of the pin is located above an arm 34 on the trigger and permits firing ; in the other position, the flange locks the trigger and prevents' firing. In the intermediate position, the cut-away flange is clear of the rib 29 and the pin and closure plate may be removed vertically. This permits the stripping of the mechanism by rearward withdrawal of the parts thereof. The smallarm may be automatic or semiautomatic and a part of the mechanism, e.g. the action-slide of a gas-operated gun, may be caught and held in the recoiled position by a spring detent 42 pivoted at 44 in the slidable cover 16. The detent is controlled by an eccentric lug 36 on the pin 24, and is thereby held inoperative when the pin is in the triggerrelease position shown.

Title: Improvements in electrical frequency divider circuits
Inventor: GOSS JOHN ANTHONY
IPC: H03K5/00
Filed: 1962-03-17
Abstract: 972,421. Transistor pulse frequency dividing circuits. RACAL ELECTRONICS Ltd. June 12, 1963 [March 17, 1962], No. 10297/62. Heading H3T. A pulse frequency divider comprises an oscillator providing output pulses at a standard frequency and a plurality of cascaded transistor monostable multivibrators, each providing output pulses at a sub-multiple of the input frequency applied thereto, the duration of the unstable state of each multivibrator determining the sub-multiple at which its output pulses appear. Negative going pulses, obtained at the collector of transistor Q3 switched on and off by oscillations from a crystal-controlled oscillator comprising transistor Q1, Q2, are passed to a first mono-stable multivibrator stage A, comprising transistors Q4, Q6, connected in cascade with two further multivibrators B, C. When a negative-going pulse occurs at the collector of transistor Q3 at the commencement of a timing period, transistor Q4 is switched on and transistor Q6 off due to the feedback through resistor R12 and capacitor C6, the potential developed across resistor R12 maintaining transistor Q5 in a cut-off state. Capacitor C6 now discharges at a rate determined by resistor R16 and rheostat VR1 and the voltage at the base of transistor Q6 decays exponentially until it becomes negative with respect to its emitter at which time transistor Q6 is switched on and transistor Q4 switched off. Q5 is now switched on and capacitor C6 charges rapidly through this transistor. The occurrence of the next negative going pulse at the collector of transistor Q3 switches on transistor Q4 again to restart the cycle. The value of the divisor is determined by the setting of the rheostat VR1 or capacitor C6 may be variable. Resistor R12 may be replaced by a diode.

Title: Improvements in or relating to co-ordinate switching arrangements
IPC: H01H67/30
Filed: 1956-04-04
Abstract: 797,913. Automatic exchange switches. SIEMENS & HALSKE AKT.-GES. April 4, 1956 [April 5, 1955], No. 10331/56. Class 40 (4). In a co-ordinate switching system in which cross-point connections between horizontal and vertical conductors are established by the energization of appropriate horizontal and vertical coils, the contact means comprising magnetic members directly influenced by the coils, magnetic shunt means is provided for prevention of contact movement when one coil only is energized. Fig. 4 illustrates the type of switch in which connection between, say, terminals 1, 5 is established by a magnetic contact assembly, sealed in a tube G, by the energization of a horizontal coil A and a vertical coil C and is subsequently held by the energization of a vertical coil H1. Each assembly is provided with a magnetic shunt comprising portions M1, M2, Fig. 3, forming air gaps L1, L2 with the contact members F1, F2. When both coils C, A are energized the fluxes due to the coils in the gaps neutralize each other, the only force thus being that in the gap U attracting the contact members together. If, however only one coil, say A, is energized, the flux in gap L2 is opposite to that in gap U so that the member F2 does not move. The vertical hold coil H1 and the vertical operating coil C are placed on opposite sides of the contact gap to avoid false operation due to the simultaneous energization of HI and A in which case the nuxes have the same distribution as in the case of the energization of coil A only. The magnetic members are preferably operated at saturation level. The multipling of the contacts may be provided by strips of magnetic material or conductors coated with magnetic material. By this means the contact strips may be polarized and the connection held by permanent magnetic uux. In this case release may be effected by reverse energization of an appropriate horizontal or vertical coil.
