In a trigger device for multi-port breech mechanism of automatic firearms having a striker 3 which is alternately cocked and released by reciprocation of the breech mechanism 8, a control lever 6 is operatively connected to both the striker and the breech mechanism. The lever 6 intecepts the released striker by way of cam and slot 10, 11 so that the striker is finally released only when the breech mechanism is in its final forward closing position. The lever 6, which is pivoted at 9 on a plate 16 mounted in turn on pivot-pins 17, 18 is formed with an inclined surface 14 that co-operates with an inclined surface 15 on the breech mechanism when the latter has moved forwardly enough to clear the locking edge 13 of the lever 6 so as to permit the lever to rise. The striker 3 which is moved forwardly by spring-loaded lever 4 meanwhile has been released by the forward movement of the breech mechanism by way of release lever 7 and the cam 10 has moved from position a to b. Only if the breech mechanism is in its closing position will the lever 6 rise enough to permit the final release of the striker to fire a cartridge. Any recoil of the breech mechanism before it remains in its closing position is arrested by contact of surfaces 14, 15. The amount of recoil may be altered by suitable distribution of the masses and inclination of surfaces 14, 15 to control the rate of fire of the fire-arm.

Abstract: 531,862. Engine turning gear. GENERAL MOTORS CORPORATION. Aug. 4, 1939, No. 22636. Convention date, Aug. 5, 1938. [Class 7 (v)] The overrunning clutch between an electric starting-motor and the starter pinion is arranged with the roller recesses in the outer member of the clutch and the cylindrical surface on the inner member and the outer member of the clutch is covered by a shell having an annular flange which retains the rollers and has an aperture through which the pinion projects. The inner member 32 of the clutch is connected to the starter pinion 33 and formed with a cylindrical outer surface which engages rollers 28 in tapering recesses 31 formed in the outer clutch member 26, which is driven by the starting motor, a shell 35 being provided having an annular flange 36 with a central opening for the pinion. The outer member 26 is rotated clockwise by the motor, and the rollers become wedged towards the end 29 of the recesses and drive the inner member 32. When the pinion and member 32 overrun, the rollers are moved to the other end of the recesses in opposition to spring plungers 40, until they. contact with stop surfaces 30. The motor, being free, then speeds up together with the member 26, but the centrifugal action on the rollers due to this rotation only tends to move the rollers outwards and further towards the stops 30, thus further releasing the clutch. A lever actuating the starting-switch for the motor also operates the lever for moving the starter pinion into gear with the engine.

Title: Improvements in or relating to light deflection systems
IPC: G02F1/31
Filed: 1965-05-28
Abstract: 1,089,636. Deflecting light. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 28, 1965 [June 8, 1964], No. 22665/65. Heading H4F. [Also in Division G4] A light deflection system comprises a biro fringent crystal 18 having a surface 20 disposed normally to the path of a plane polarized monochromatic light beam 12 and parallel to the optic axis 22 of the birefringent crystal, and a surface 24 which is so oriented that the angle of incidence of light beam 12 lies between the two critical angles for total internal reflection of crystal 18 which correspond to the light beam being either horizontally or vertically polarized (i.e. depending on whether the incident light beam 12 functions as an ordinary or extraordinary ray in crystal 18). If light beam 12 is vertically polarized it is transmitted through surface 24 undeflected but if the light beam is horizontally polarized it is totally internally reflected by the surface 24 as a deflected beam, or vice versa depending on the direction of the optic axis 22. Correcting birefringent crystal 26 which is an exact duplicate of crystal 18 and separated therefrom by a small air gap (exaggeratet as shown) is included to align the vertically polarized light beam along the path originally taken by the light beam 12 due to the small downward refraction at surface 24 when the vertically polarized light beam enters air gap 28. The horizontally polarized deflected beam is returned to a path which is aligned with but physically displaced from the path of the vertically polarized light by means of a birefringent crystal or glass prism 30, the light being reflected by surface 32. The light source may comprise a laser and a polarizer and a number of these light deflection systems may be arranged in series, Fig. 4, not shown, each being associated with an electro-optic phase control means to which half-wave voltages may be applied to change the plane of polarization of the light beam by 90 degrees in order that different characters arranged in different positions on a mask may be projected when required on to a screen, the deflected light beams after passing through the mask being deflected back to the original light path by a similar number of light deflection systems. In a further embodiment, Fig. 5, not shown, a pair of deflectors as shown in Fig. 1 are mounted back-to-back which results in one set of beams being deflected upwardly and the other set downwardly. To equalize the optical path lengths of the deflected and undeflected light beams a birefringent element is positioned in front of the deflection system and arranged so that its optic axis is orthogonal to the optic axis of the birefringent element which internally reflects the deflected beams, Figs. 6 and 7, not shown. Birefringent crystal 18 may comprise sodium nitrate or calcite and correcting crystal 26 may comprise sodium, fluoride or sodium nitrate.
