Patent GB-589394-A (GB)
Title: Improvements in and relating to self-loading rifles and machine guns
IPC: F41A9/38
Filed: 1945-02-05
Abstract: 589,394. Firearms. HALL, J. E. M. Feb. 5, 1945, No. 2866. [Class 119] A self-loading rifle, or machine gun, is provided with a cartridge transporter 14 for feeding the cartridges from a magazine 33 to the breech chamber, gripping mechanism carried by the transporter for gripping the empty cartridge cases, a transversely movable breech block 4, which co-operates with the transporter when in its forward position, a firing pin on the breech block, and a spring-loaded hammer 42, controlled by a trigger 36, the breech-block, transporter and hammer being actuated by a gas piston 26 when a shot is fired, and the return movements of the breech block and transporter being subsequently effected by spring means in timed relationship. In the construction shown, the transporter has a lug 20 for guiding it in a track 21 of the rifle, a pin 22 for connection to a spring-controlled link 23, whose crosshead 29 is acted upon by rod 27 of piston 26, a semicircular cartridge gripping member, and a pivoted plate 17, as shown in Fig. 7. The breech block has a channel 6 to receive the rear ends of the cartridge, a spring-loaded lever 8, which when struck by the hammer actuates the firing pin, and inclined ribs 5 which engage in inclined grooves in the rifle. The front of one rib has a lateral projection which engages in groove or slot 12, Fig. 1, of a plate 13, which is connected to a spring-controlled rod 30, whose crosshead 28 is also engaged by piston rod 27. The trigger 36 is pivoted on a pivoted rear lever 37, having an abutment 38 which connects with an abutment 39 on a spring-loaded rod 40, pivotally connected to hammer 42. An auxiliary pivoted sear 45 is adapted to hold the hammer in its retracted position if the trigger is held retracted after a shot is fired. Operation.-A pull on the trigger releases rod 40 and hence the hammer which flies forwards to strike lever 8, and a shot is fired. Gas piston 26 then moves to the rear and acts on rod 30, which causes the breech block to move down its inclined guides, withdrawing a cartridge slightly from the chamber. When gripping member 16 on the descending transporter meets the cartridge case the plate 17 swings, as in Fig. 7, so that its arms 17a, 17b, grip the case. The piston rod now moves crosshead 29 for the transporter to the rear, a pawl 48 on the transporter serving to engage and thereby retract the hammer. Near the end of the transporter's movement the arm 17a coacts with a stop 47 and ejects the case through a trap door 24. When the transporter moves forward, under spring action, its arm 17a carries a cartridge from the magazine to the chamber, the arm being eventually released by a cam 10 on the rising breech block. The return movement of the breech block is prevented by a spring- loaded pawl, which projects into its path until moved away by the transporter, when the latter is in its fully forward position.

Abstract: 1401084 Modulating light HEWLETTPACKARD CO 21 July 1972 [10 April 1972] 3134/75 Divided out of 1401083 Heading H4F In a tunable optical filter of the type wherein a portion of a plane polarized optical beam 3 traversing a photo-elastic birefringent crystal 1 is diffracted by a collinear acoustic wave S 2  into an othogonal plane of polarization, and subsequently filtered by a polarization analyser 14, the optical output face 7 of the crystal has a normal which is inclined out of the plane defined by the input optical polarization vector Li and the acoustic group velocity vector (the acoustooptic interaction plane), whereby the acoustic energy is reflected out of the interaction plane and may be scattered into a number of modes. In this manner undesired acoustic resonances and optical interactions with the reflected wave(s) are reduced. In Fig. 1, the acoustic group velocity rector is parallel with beam 3. The input face 6 is inclined about an axis X and the output face about an orthogonal axis 7, preferably through the Brewster angle. A shear wave S 1  is reflected at face 6 to provide wave S 2  with polarization along the X-axis. The crystal may be of LiNbO 3 , PbMoO 4 , quartz or CaMoO 4 . The latter is acoustically isotropic and the angle between the normal of face 7 and the Y-Z interaction plane is preferably 26 degrees. LiNbO 3 , quartz and also proustite Ag 3 AsS 3  are acoustically anisotropic, and for the first two materials the normal of face 7 is preferably at 30 degrees to the Y-Z plane. The collinear acoustic wave may alternatively be a longitudinal wave. The crystal may have an acoustically and optically absorbing coating as described more particularly in Specification 1,401,083.
