Title: Shock absorbing device for firearms
IPC: F41A25/16
Filed: 1972-02-28
Abstract: 1386823 Recoil modifying INTERNATIONAL VIBRATION ENG and AVIONS MARCEL DASSAULT 28 Feb 1972 [1 March 1971] 9042/72 Heading F3C [Also in Division F2] A resilient assembly such as a series of biconical rings 6, Fig. 1, or of annular cushions 14 of knitted steel thread, Fig. 5, and a friction assembly (wedge-shaped segments 8 with friction linings 9, and a wedge ring 7) are mounted between a movable member (sleeve) 1 and a support (tubular casing) 2 to absorb the energy of recoil F imparted to the member 1, e.g. by an aircraft cannon mounted therein, and to return the member after recoil, an element (segment 8) of the friction assembly being moved from an advanced position (as shown), with the member 1, during recoil, to a position in which it engages an abutment 10 secured to the support 2 so that there is a relative movement and friction between the element and the member 1 during further recoil movement, a complementary element (ring 7) being biased against the friction element 8, during recoil, by a resilient assembly (Belleville washers 12 or 18, or annular cushions similar to those 14, Fig. 5, which are outside the casing 2). The sleeve 1 slides on guides 3, 4 in the casing 2. To allow limited axial movement of the segments 8, they are hooked on to the abutment, a flange 10 of an end ring 5 of the casing 2 around the sleeve 1. They are biased by a weak spring 11, in the direction of the recoil F, i.e. toward the wedge ring 7. In both Figs. 1 and 5, the recoil F of the cannon or other weapon is first borne by the spring 6 or 14 by way of the sleeve 1 and then the latter, because of the friction linings 9, urges the wedge ring 7 by way of the segments 8 to compress the spring 12 or 18. In Fig. 1, an abutment 13 fixed to the sleeve 1 allows the spring 12 to expand, with continuing recoil of the sleeve, and permit sliding of the ring 7 and thus lessen the frictional force of the linings 9 on the sleeve. The spring 6 returns the sleeve 1 to the position shown and this movement is cushioned by the spring 12. In Fig. 5 the compression of the spring 18 is limited and so there is not the lessening of the frictional force during recoil as in Fig. 1 due to extended movement of the wedge ring 7. A fixture 17 in the casing 2 acts as an abutment for the spring 18 and a spring 15 of members like the cushions 14 acts to cushion the return of the sleeve 1 after recoil.

Abstract: 1,209,357. Vibration dampers. MASCHINENFABRIK STROMAG G.m;b:H. 27 Feb.,. 1968 [16 Nov., 1967], No. 9437/68. Heading F2S. A torsional vibration damper consists of inner and outer generally cylindrical members 1, 5 provided respectively with radially outwardly and inwardly projecting annular discs 2, 7 which interdigitate. The members 1 and 5 are drivingly interconnected by a resilient element 4 which, together with the members themselves, defines a sealed chamber enclosing the interdigitating discs. This chamber also contains a vibration absorbing medium, which may be a liquid, a tar-like substance or particulate solid and which fills the spaces between the discs. When the medium is a highly viscous liquid whose viscosity falls with increasing temperature, an air vent 11 may be provided. This is normally closed by a ball 12 which may either be fusible at a temperature at which the liquid viscosity becomes unacceptably low, or merely be displaced by expansion of the liquid. In either case, the admission of air restores the liquid to an acceptable viscosity; and where the fusible ball is employed, the consequent fall in temperature causes it to re-solidify and reseal.

Abstract: 703,772. Electromagnetic-interrupters. BRISTOL CO. April 26, 1951, No. 9752/51. Class 38(5) [Also in Group XXXV] A synchronous contactor operated by A.C. in a winding 21 comprises a permanent magnet 19 with two pole structures 15, 16 providing two gaps 17, 18 through which the magnetic flux passes in parallel, a yoke 20 carrying the winding 21 and supporting two steel blades 24, 25, which move respectively in the gaps 17, 18 and carry contacts 26, 27 movable between two pairs of fixed contacts 32, 34 and 33, 35. Metal bars 30, 31 connect contacts 32, 33 and 34, 35, and each bar carries a terminal such as 43. In action, the blades 24, 25, move in opposite directions, and the arrangement constitutes a reversing switch so that if D.C. is applied to the two terminals 43, and the contacts 26, 27 are connected through flexible leads 40, 41 to terminals 38, 39 connected respectively to the ends of the primary winding of a transformer, A.C. will be delivered to this primary winding. The blades 24, 25 are constructed so as not to be resonant and they become magnetically saturated when the magnetomotive force due to the coil 21 has reached only a small proportion of its maximum value. This causes contact to be made during a large portion of the cycle without excessive contact pressure. The fixed contacts, such as 35, Fig. 9, may be adjustable by screws 45 and present rounded and tapered ends to the moving contact 27, affording a line contact, and one which is selfcleaning. Specification 686,890 is referred to.
