IPC: F41A25/18
Abstract: 132,095. Soc. Anon des Etablissements Delaunay-Belleville. May 1. 1918. [Convention date]. Recoil apparatus.-Relates to differential-recoil apparatus of the kind having run-out springs surrounding the barrel, and consists in providing the springs with specially arranged abutments which permit them to act also, in case of misfire, as buffer springs at the end of run-cut. In the case of a retarded fire the barrel attaches itself to a special recoil brake. Fig. 1 shows the gun in the recoil position in which it is retained against the action of run-out springs 4 by a ball-brake retaining device 8. The run-out springs are arranged between collars 6, 7 adapted to move over the outside of the gun barrel 1. During recoil, the springs 4 are compressed from the front end against a fixed abutment 2, and towards the end of run-out, if a misfire occurs, projections 11 on the barrel engage the collar 7 and compress the springs 4 from the rear end against a fixed abutment 13. In the event of the gun firing so late that the barrel is at rest, or nearly so, in the forward position, a catch 14 engages teeth 15 on the piston-rod of a liquid brake, the piston of which has a cup-leather 18 and also a spring-loaded valve 16 covering ports in the piston, which valve opens gradually to oppose resistance to the recoil of the barrel. The catch 14 is released by operating a screw 19, whereupon the brake piston is returned to the front by a spring 20.

Title: Muting circuit for radio receivers
Inventor: BIDWELL BRIAN ALFRED
IPC: H03G3/34
Filed: 1966-03-25
Abstract: 1,102,088. Transistorized muting circuit. STANDARD TELEPHONES & CABLES Ltd. 25 March, 1966, No. 13272/66. Addition to 1,064,107. Heading H3T. In a muting arrangement for a radio-receiver, the frequency response band of a sampling circuit, which is narrower than the frequency response band of the receiver, is cyclically swept over a frequency band which includes at least part of the receiver frequency response band, the sweep being stopped in response to the received signal exceeding a threshold value in the sampling circuit, and the output signal of the receiver is produced in response to the received signal only when the sweep is stopped. The sampling circuit 4 comprises inductor 36 and series-connected capacitor 38 and varactor diode 37, the capacity of which is cyclicly varied by a saw-tooth voltage developed across capacitor 38 by means of sweep generator 5 and hold circuit 6. Saw-tooth sweep generator 5 comprises forward-coupled transistors 42, 43, 48, with a back-coupling path from capacitor 38 to the base of transistor 42. An input from the I.F. circuits of the receiver is applied via limiter 9 to a sampling circuit 4; if a signal is intercepted at any point in the scanning cycle it is amplified by an amplifier comprising transistor 60 and then applied to a peak detector comprising transistor 65, which is so biased as to respond only to signals exceeding a threshold determined by variable resistor 70. The resulting change in collector current produces a drop in potential across resistor 50 which causes the sweep generator to stop; diode 39, in hold circuit 6 then becomes non- conductive so that the potential across capacitor 38 remains held at its instantaneous value. An output from sweep generator 5 is derived from the emitter circuit of transistors 42, 43 and is applied to rectifying and smoothing circuit 8, to produce a D.C. voltage which maintains the receiver muted so long as sweeping occurs, but which disappears and immutes the receiver when sweeping ceases.
Patent GB-132931-A (GB)
IPC: D03D49/06
Abstract: 132,931. Preston, E. E., and Mercia Fabric Co. Nov. 13, 1918. Warp let-off and tensioning mechanism.-Relates to a combined warp let-off and warp tension mechanism, particularly applicable to warp kniting machines. The action of the warp let-off mechanism is controlled by a. tension frame, the object being to provide a sensitive control with a minimum variation in tension. A.n eccentric faced pivoted brake member 11 bears on the V- shaped groove 10 of a pulley 9 connected by gearing 5, 6 with the beam 1. The pressure of the cam face 12 on the pulley 9 is regulated by the tension of the warps which pass over a rod or roller 3 on a bell-crank lever 18 and by acting against the spring 29 cause a projection 21 of the lever 18 to bear on the rear end 22 of the member 11. In a modified form, the warps support the bell-crank lever 18, and when their tension increases, lift, by means of the projection 21, the rear end 22 of the brake member 11 so as to free the pulley 9 or warp beam 1. There may be a pair of brake blocks acting on opposite sides of the brake wheel and operated by a cam or incline on the pivoted frame.

Abstract: 791,793. Circuits for loud-speakers. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 2, 1956 [May 5, 1955], No. 13544/56. Class 40 (4). In a low-frequency amplifier a high-tone and a low-tone loudspeaker are connected in series in the anode circuit of a screen grid valve, the input impedance of the lowtone loud-speaker being connected between the anode and the screen grid of the valve and being shunted by a capacitor which offers a low impedance to the high-frequencies of the audiofrequency spectrum. As shown in Fig. 1, the high-tone loud-speaker 16 has a low impedance so that for low frequencies the screen grid 18 is substantially at the potential of battery 8 and the valve acts as a pentode with a high gain and with a high distortion factor that is of no consequence to the low-tone loud-speaker 12. For high frequencies loud-speaker 12 is shortcircuited by capacitor 17 so that the anode and screen grid are effectively connected together and the valve acts as s triode with a low gain and a low distortion factor. The invention may be applied to a push-pull arrangement using two pentodes. Specification 496,883, [Group XL], is referred to.
