Title: Improvements in or relating to automatic firearms
IPC: F41A3/26
Filed: 1939-07-13
Abstract: 532,129. Automatic firearms. CESKOSLOVENSKA ZBROJOVKA AKCIOVA SPOLECNOST. BRNO. July 13, 1939, No. 20483. Convention date, July 13, 1938. [Class 92 (ii)] An automatic firearm in which the breechblock is locked and unlocked by the movements of a breech-block carrier is provided with a buffer between the breech-block and the breechblock carrier, this buffer absorbing energy during recoil and applying this energy to accelerate the forward movement of the breech-block carrier after the breech-block has reached the locking position. The buffer may consist of two symmetrically-disposed springs 17 mounted on rods 18 which have curved heads 19 seating in recesses in the rear part of the breech-block 5, and which are guided in eyes in a lug 20 on the breech-block carrier 3, against which lug the springs 17 abut. The breech-block carrier, on actuation by the gas-piston 4, compresses the springs 17 and after the passage of a projection 9 on the carrier from the locking-position shown in Fig. 1, beneath the breech-block, a part 8 on the carrier tilts the breech-block downwardly so that its end face is caught by the shoulder 25 at the front of the projection 9, Fig. 2. On the toward movement of the breech-mechanism under the influence of the recoil spring 15, guides 13 on the breech-block engage studs 14 on the breech casing, whereupon the breech-block is raised into the closed position, thus allowing the springs 17 to accelerate the final forward movement of the breech-block. carrier, during which movement the part 8 strikes the firing pin 21. According to a modification the breech-block is formed as a rotary cylinder with forward locking-lugs, and is rotated and moved rearwardly by a strikerpost on the carrier which passes through a curved slot in the wall of the breech-block. The buffer in this modification consists of a spring mounted on the rear end of the breech-block between a collar thereon and the rear face of a shoulder on the breech-block carrier.

Title: Improvements in friction lifters for lifting the tups of drop stamps or for other like purposes
IPC: B21J7/36
Filed: 1921-08-02
Abstract: 187,057. Massey, Ltd., B. & S., and Massey, H. F. Aug. 2, 1921. i I Power hammers.-Friction lift drop stamps in which the hand cord g, Fig. 1, for actuating the clutch lever e may be pulled automatically to give a series of blows, have the cord attached to a disc h, Fig. 2, arranged on the rotating shaft a between two collars i, j feathered thereon and adapted to be pressed together and released by self acting mechanism in order to grip and release the cord. The collar i does not move relatively to the shaft except for axial adjustment by a screwed sleeve 9, but the collar j is moved axially against one or more springs (not shown) by a cam ring l on a sleeve g which oscillates with the arm c of the main clutch and is engaged by rollers p of abutting ring m, of which the oscillation is limited by chains t, u connected to adjustable levers or stops. When owing to the fall of the tup the arm c and the ring l are rotated in one direction, the ring m is arrested by the chain t as the tup comes near the bottom of its stroke, and the rollers p pass onto the raised parts of the cams n, o, Fag. 6, thus gripping the disc between friction rings 10, 11 of the rotating collars, pulling the rope g, and raising the tup. At the top of the stroke the reverse operation takes place. The ring m has powerful spring pins v engaging a nut x on the sleeve q which is retained by a collar y fixed on the shaft a.

Filed: 1944-10-23
Abstract: Acids of the general formula <FORM:0588108/IV/1> wherein X1 represents chlorine or an acylamino-group and X2 represents hydrogen (or chlorine when X1 represents chlorine) are obtained by treating the appropriate substituted p  benzene derivative of the general formula <FORM:0588108/IV/2> with maleic anhydride in the presence of a Friedel-Crafts' condensing agent, e.g. anhydrous aluminium chloride, in the absence of a solvent or in solution in an inert solvent, e.g. carbon bisulphide or petroleum ether.  The products exert a strongly bacteriostatic action.  In examples: (1) chlorobenzene and maleic anhydride in dry petroleum ether are heated on a water-bath with aluminium chloride to produce p-chlorobenzoylacrylic acid; (2) acetanilide and maleic anhydride in dry carbon bisulphide are treated with anhydrous aluminium chloride and the reaction-mixture is heated on a water-bath to yield p-acetaminobenzoyl acrylic acid; (3) 1 : 3-dichlorobenzene and maleic anhydride in dry carbon bisulphide are treated under reflux with anhydrous aluminium chloride to give 2 : 4-dichlorobenzoyl acrylic acid.  The Provisional Specification states that, in the above general formul , X1 may represent chlorine or a substituted amino-group, and X2 hydrogen, chlorine or a substituted amino-group.
