Title: Improvements relating to dry shavers
IPC: B21D22/10
Filed: 1962-05-25
Abstract: 934,548. Making dry shavers; punching. CARINTHIA-ELEKTROGERATE G.m.b.H. May 25, 1962 [June 16, 1961], No. 20264/62. Classes 83 (2) and 83 (4). In a method of making a shearing foil for a dry shaver, the foil is supported by a deformable pad enclosed on all sides and acted on by a punch the operating face of which is formed with raised parts, the recesses therebetween corresponding to the shape of the desired foil, the raised parts being tapered in cross-section so that the edges of the parts of the foil entering the recesses are bent to form flanges the edges of which are subsequently machined parallel to the main faces of the foil. An apparatus for performing the method comprises an enclosed rubber pad 2 and a punch 4A which has recesses 5A in its operating face. The recesses have flat or slightly arched bottoms and tapering sides and form a network which has the form of the desired finished shearing foil. After punching the waste parts 3B remain flat and the parts 3A remaining in the foil are bent over so that a cutting angle α of about 70 degrees is obtained. The edges of the bent-over parts are then ground and lapped to form surfaces which lie in a plane F parallel to the main surfaces of the foil.

Title: Improvements in and relating to message-carrying shells
IPC: F42B12/36
Filed: 1937-07-22
Abstract: 481,254. Projectiles. CHEVRIER, M. July 22, 1937, No. 20354. [Class 9 (i)] Relates to a messagecarrying projectile of the type adapted to be fitted onto the barrel of a firearm and having a hollow space in its interior for the reception of a message. According to the invention, the space within the interior of the projectile for the reception of the message is constituted by a hollow cap portion which is connected to a crown or body member of the projectile by means of a metallic strip, such assembly being mounted, through the intermediary of a cylinder-like extremity, on a wooden mandrel adapted to be fitted on the barrel of the firearm and to remain associated therewith upon discharge of the projectile. As shown, the hollow cap portion 1 which receives the message is connected to the body member 3 by a metallic strap 7, the member 3 being connected by a sheet-metal cylinder 10 to the wooden mandrel 9 provided with an axial perforation 12 to enable it to be fitted on the gun barrel: The member 3 is provided with a tapped axial boss 4 which receives a casing 5 into which a cartridge 6 containing a smoke-producing composition is inserted. The casing 17 of this cartridge is formed with vents 18 and the lower end thereof is adapted to fit over a closing member 19 containing the primer 16 and striker 20. A flange 22 on the member 19 which fits into the casing 5 is provided with perforations 23 which are in communication with the vents 18 through the annular chamber in the casing 5. A rubber ring 14 is held in position in the bore 12 by a stamped sheet-metal framework 15 which is shaped so as to form between the projectile and the mandrel an expansion chamber for the gases issuing from the gun barrel. The smoke emitted by the cartridge 6 issues through the vents 18 and perforations 23 and indicates the trajectory of the projectile, the whistling powers of the smoke-producing powder serving moreover to indicate exactly the point where the projectile falls.

Title: Improvements relating to alloys
IPC: C22C21/00
Filed: 1930-07-08
Abstract: Tin is incorporated in aluminium or in aluminium alloyed with small quantities of other metals such as manganese, lead, &c. by displacement from tin oxide by reaction with magnesium in the form of an alloy, for example with copper or zinc.  The magnesium alloy containing for example 90 per cent of zinc and made by melting the metals together in a reducing atmosphere, is first prepared and after being comminuted is covered with tin oxide powder, preferably admixed with zinc oxide to render it porous.  The reduction takes place in a crucible at red heat in a reducing atmosphere.  After raising the temperature to the melting point of aluminium or over, aluminium or aluminium alloy is added.  The amount of magnesium alloy employed having regard to its magnesium content may be just sufficient to reduce the tin oxide, or an excess may be used when magnesium will be present in the final alloy in addition to the other metals such as copper, zinc, &c. The cast ingot while hot may be further treated with steam, and for rolling it is first heated at about 150-200 DEG C. and then rolled at this temperature while being subjected to the action of steam.  Further rolling is continued at about 75 DEG  or 100 DEG  C. when the thickness is reduced to 0,25 inch.  For certain purposes the rolling may be preceded by drawing, preferably at about 150-200 DEG  C.
