Abstract: 646,878. Securing wall boards. CAFFERATA, G. W., BRITISH PLASTER BOARD, Ltd., and GYPROC PRODUCTS, Ltd. May 12, 1948, No. 13045. [Class 20(iv)] Sheets, e.g. of wall-board, are attached to walls or ceilings by battens secured in position with cementitious material, the battens being provided with members which are directed outwardly between adjacent sheets and are clinched over to hold the edges of the sheets. In Fig. 2, the batten consists of three strips 20-22 of plaster board with spaced nails 23 having their points directed outwardly and their heads contacting with the strip 20. The batten is secured to the wall 24 by a layer 25 of gypsum cement, blobs 26 being added to key the sides of the batten to the wall. When the sheets are applied to the battens, the nails are bent alternately in opposite directions to hold the edges of the sheets. Intermediately arranged battens have more widely spaced nails which penetrate the sheets and are clinched over. A piece of woven wire or expanded metal may be secured to the underside of the strip 20 by large headed nails, the woven wire extending beyond the edges of the strip 20. When the batten is applied to the wall, the woven wire is embedded in the cementitious material. A damp excluding strip of bitumen felt may be placed between the strips 20, 21. In Fig. 7, the batten consists of a strip of plaster board broken along its centre line and folded to form a V-shaped channel having side walls 29. The clinchable members 30 are tapered sheet members having flanges 31 at the broad ends which are embedded in gypsum plaster or cement filling the channel. The batten is secured by cementitious material 33 and the side blobs 34 may be carried over the top of the walls 29 to increase the bearing surface for the sheets 27. A strip of woven wire or expanded metal 36 is impaled over the members 30 which are hammered over to hold the sheets. The finishing plaster coat 37 is then applied. In a modification, wooden battens of small cross-section are secured to the wall by cementitious material, the clinchable members being of wire, bent L-shape, passing through the batten at intervals and having one limb of the L engaging a strip of expanded metal on the underside of the batten.

Filed: 1966-03-25
Abstract: 1,143,967. Sabot projectiles. OERLIKONBœHRLE HOLDING A.G. 25 March, 1966 [1 April, 1965], No. 13326/66. Heading F3A. A rotary discarding sabot projectile assembly comprises a sabot 10 and a projectile 11 which is supported at its rear face by a first abutment 107 and is secured by a locking member, e.g. a split ring 15, which engages a surface 114 in a recess in the projectile and the surface 171 of a screw-threaded second abutment 17 which is axially movable in the sabot to adjust its clamping action but which is normally locked against rotation by a screw 20, the first abutment 107 being deformable axially by the rear face of the projectile 11 when the assembly is fired to permit the projectile to move rearwardly, under inertia, with respect to the sabot, to disengage the locking member from the surface 171 and to bring the rear face of the projectile into operative engagement with the sabot, whereby the rotary motion of the sabot is transmitted to the projectile 11 and locking member 15, which, under the action of centrifugal force, expands radially outwardly to free the projectile. Faces 112 provided at the rear of the projectile increase its grip in the sabot on axial displacement. A threaded, projectileguiding member 14 at the front end of the sabot permits air to enter the body of the sabot, whereby the rate of separation of the projectile and sabot after firing is increased. Rotation is transmitted to the assembly by driving bands 12 and 13. In a modification (Fig. 7, not shown), the locking member comprises a sleeve (15d) divided into a plurality of fingers (28) which bend outwardly under centrifugal force. In another embodiment the first abutment (23, Fig. 4, not shown) is screw-threaded into the rear of the sabot and the second abutment (173a) is a fixture in the sabot. In further embodiments the first abutment comprises a resilient spring (107c, Fig. 6, not shown) which also assists in the separation of the sabot and projectile, or an upsettable element (107b, Fig. 5, not shown).

Filed: 1962-04-06
Abstract: 997,811. Cupping. BUDD CO. April 6, 1962 [April 19, 1961], No. 13398/62. Heading B3Q. A method of forming a thin metal sheet into deep-drawn configurations is characterized by the steps of bonding the thin metal sheet to a thick metal sheet to produce a laminated sheet, of forming the laminated sheet in a forming machine having a male die, and completely removing said thick sheet of said laminated sheet from the thin sheet article. The laminated sheet 10 is cupped in an hydraulic press comprising an hydraulic cylinder 14 which actuates an upper hold-down ring 16 to grip the sheet against a lower stationary ring 18 with sufficient pressure to prevent buckling during the cupping operation. A cupping die 26 is actuated by an hydraulic cylinder 22. After the cupping operation the thicker sheet 28 is removed by heating or chemical etching after the formed laminated sheet has been annealed to remove any internal stresses created by the cold working. In an embodiment the laminated sheet comprises a thin stainless steel sheet 27 bonded to a relatively thick carbon steel sheet 28 by soldering, brazing, welding or hot roll bonding. The thick sheet is at least five times the thickness of the thin sheet and the blank lying between the blank holders is lubricated to create a uniform coefficient of friction in the blank holders. The hold-down pressure is held constant by providing a draw bead groove and mating projection on the hold-down rings. The thin sheet maintains its original thickness during the deep drawing operation. In another embodiment a hemisphere is formed from a laminated blank comprising a sheet of stainless steel sandwiched between two supporting layers of carbon steel. Two such hemispheres may be welded together to form containers for rockets or missiles. Specification 871,269 is referred to.
