Title: Firearm with safety mechanism
IPC: F41A17/64
Filed: 1976-06-08
Abstract: 1514129 Firing pin satefy mechanism SIG SCHWEIZERISCHE INDUSTRIE-GES 8 June 1976 [27 June 1975] 17349/76 Heading F3C The cartridge of an automatic pistol is fired by a firing pin 17 normally prevented from moving by a first spring-biased safety bolt 18. A second safety bolt 19 is spring-biased out of engagement with the pin 17, but is arranged in parallel with the first bolt 18 so as to engage and lock the firing pin 17 if the first bolt is jolted out of engagement unintentionally by an impact. If the pistol is dropped so that the impact forces jolt the first bolt 18 out of engagement, then the same forces automatically jolt the second bolt 19 into engagement. Additionally, the hammer 12 and firing pin carrying slide 16 are mounted so that any jolted sliding of the slide 16 brings the slide and not the firing pin 17 into contact with the hammer. In normal operation with the hammer 12 cocked and held by a catch lever 13 actuation of the trigger 14 moves the trigger arm 20 to push a release lever 21, which moves the first safety bolt 18 to a release position. Then arm 20 frees the catch lever 13 to release the hammer 12, which strikes the firing pin 17 to ignite the priming cap of the cartridge in the barrel 15. The released gases push the slide 16 towards the hammer 12 to eject the spent cartridge case and cock the firing mechanism. Spring return of the slide loads a new cartridge from a magazine (not further disclosed). The barrel 15 is a press fit in the pistol casing.

Filed: 1975-04-30
Abstract: 1501730 Diode detectors INTERNATIONAL STANDARD ELECTRIC CORP 30 April 1975 [7 May 1974] 18046/75 Headings H3Q and H3T In a r.f. detector operating linearly down to very low signal levels having two branches, each including a diode D1, D2, Fig. 3, which conducts during a half-cycle of different polarity from the other and a resistor R1, R2 in series with each diode to supplement the forward resistance of each diode to provide a required input impedance, each diode is biased to its knee voltage by a respective bias voltage U V1 , U V2  provided by means Al, A2 simulating such voltages whereby symmetrical half-wave currents are derived in the initial regions of the diodes i.e. at very low input signal level and a demodulated signal is obtained at Vo, from the arithmetic mean of the diode currents derived from an input signal Vi, by evaluating means A1, A2 which do not reflect impedance changes into the input impedance of the detector. As shown a bias source U is connected to an integrated or discrete component inverting operational amplifier A2 which provides a virtual bias source U v2  with reverse sign and a source resistance tending to zero but with equal amplitude. Similarly an operational amplifier Al having a negative feedback network GK provides a virtual bias source U v1  with equal sign and a source impedance tending to zero. The bias source U can be replaced by a resistor R3 and a diode D3, Fig. 5, and non-linearity for low input voltages Vi > 50 mV can be compensated for (Fig. 6, not shown) by including a diode D4 in series with a resistor R4 in the negative feedback network of A1. The output can be from A1 and ground (Fig. 4, not shown) or as shown from R7 and R8 which function to eliminate the D.C. component of the output signal. In the arrangements described above only one branch and only one half cycle is used to derive the demodulated signal, while the second branch only serves to ensure a defined input resistance equal during both half-cycles. In a fullwave circuit (Fig. 7, not shown) amplifier A2 is replaced with circuitry similar to amplifier Al and a demodulated output signal is derived from a differential amplifier DA. Schottky diodes may be used instead of point-contact diodes for frequencies above the v.h.f. region. Resistors R1 and R2 may be in chip form.
