Abstract: 774,069. Finishing cartridge cases. DU PONT DE NEMOURS & CO., E.I. Oct. 19, 1955 [Nov. 22, 1954], No. 29798/55. Class 9 (1). Apparatus for bending the flexible lines of a cartridge case over the rim comprises a support 2 on which is mounted, above a bracket 4, a fluid cylinder 3. The cylinder piston 6 has a stem 7 carrying a second cylinder 8 attached to a hollow shaft 9 extending through the bracket 4. At the lower end of the shaft 9 is an upper press element 12 through which passes the stem 11 of piston 10. Attached to the stem 11 of piston 10 is a lower press element 13 which holds a tubular ring 14 of resilient compressible material between the element 12 and a flexible guide 15 attached to the element 13 and to a housing 5 carried by the bracket 4. When a case 16 with a liner 17 is in position below the press, fluid is admitted to the cylinder 3 to depress the piston 6, so that the press elements enter the case. Fluid is then admitted to the lower cylinder 8 to raise the piston 10 and so compress the ring 14, which is thus forced outwards against the liner 17. The stroke of cylinder 3 is then reversed, so that the expanded liner is forced over the edge of the case 16, Fig. 2, by the guide 15 as the guide moves upwards in the housing 5. Piston 6 is then arrested and piston 10 depressed to release the case. The guide 15 may be in one piece or in strips and made from leather, rubber or synthetic plastic materials. The ring 14 is preferably of rubber or synthetic plastic and the liner 17 may be of rubber, polyethylene or other plastic film. The cylinders 3, 8 may be pneumatic or hydraulic. Suitable mechanical means such as cranks, racks or pinions may replace the fluid cylinders. The operation may be carried out horizontally or in any other convenient position.

Title: Control mechanisms for delayed arming of guided missiles
Inventor: JACOB JOHN EDMUND BALDWIN
IPC: F42C15/24
Filed: 1962-08-03
Abstract: 1,046,249. Locking rotary elements. BRITISH AIRCRAFT CORPORATION (OPERATING) Ltd. July 31, 1963 [Aug. 3, 1962], No. 29852/62. Heading F2E. [Also in Division F3] A control mechanism for the delayed arming of a guided missile warhead includes a rotated member with projections and an arresting member movable in response to an actuating force between one position in which it engages a projection on the rotated member and another position in which it is clear of the rotated member, being such that once a projection is engaged both the rotated and arresting members become permanently locked in that position. The mechanism comprises a rotated disc 16 (Figs. 1 and 2, not shown) with a series of projections 25 driven by a clockwork device 17, 18, and an acceleration sensitive plunger 28 having a head 31 and being movable axially along a housing 26 against a compression spring 29. In operation a plunger 19 is moved by an explosive device to allow the disc to rotate and provided the acceleration is of sufficient magnitude the plunger 28 is moved against the spring so that the head 31 is clear of the projections 25 and the disc continues to rotate for about 2¢ seconds until a catch 20 reaches a fixed stop 21 to halt the disc at a chosen position in which a detonator 23 within the disc lies between an adjacent an igniter and cartridge 14, the igniter being operated by a crush switch (not shown) on a warhead 10. Except when the catch 20 and stop 21 are engaged the igniter and cartridge are separated by the disc and detonation of the warhead is prevented. Should the acceleration become too small during the period of rotation of the disc, the plunger 28 is returned by the spring 29 and the head 31 will permanently engage with one of the projections 25 to arrest the disc and lock the mechanism in a safe position. The projections 25 are irregularly spaced so that one will engage the plunger 28; if this should oscillate in its housing. The acceleration sensitive plunger may be replaced by a solenoid operated plunger connected to a safety circuit.

Title: Grinding machine-steadyrest
IPC: B24B41/06
Filed: 1945-11-09
Abstract: 601,357. Grinding-machines. NORTON CO. Nov. 9, 1945, No. 29901. Convention date, March 17. [Class 60] The steadyrest of a grinding machine comprises a steadyrest frame pivoted to a base and'carrying an adjustable shoe, or shoes ; an arm pivotally mounted on the base and connected to the frame for swinging it into and out of the operative position, and an automatically operating means for adjusting the shoe on the frame to maintain it in effective engagement with the work during a grinding operation. As shown, the invention is applied to a machine for grinding crankshafts as described in Specification 480,888, the steadyrest comprising shoes 28, 29 carried by a frame 26 which is pivoted on an axle 27 on a base 15 which is clamped by a block 20 on the worksupporting table 10. The base is formed as a hollow casing which receives the frame 26 when it is swung to its inoperative position. The frame 26 is operated by a hydraulic piston 60 connected by a link 57 to a lever 45 pivoted at 46 and having an end roller 47 which runs on a flat track 49 on the frame 26. Disengagement of the roller from the track is prevented by reduced ends of the roller axle engaging recesses 52 in the frame. Upward movement of the frame is limited by an adjustable stop 54. Preliminary manual setting of the shoe 28 is effected by a knob 31 on a screw 32 threaded into a slide 30 carrying the shoe. The shoe 29 is set by a knob 38 on a screw 39 threaded into a slide 34 having a cam-face 35 which engages a roller 36 on an arm 38 pivoted at one end at 22 and carrying the shoe 29 at the other end. When the frame 26 is swung into the operative position, the shoes 28, 29 are, as described below, held out of contact with the work 12, so that the grinding wheel 11 may make a preliminary cut. The rests are then simultaneously, or in sequence, allowed to come into contact with the work under the pressure exerted by springs 77, 87 which move racks 71, 81 engaging with pinions 70, 80 on the screws 32, 39. The springs 77, 87 are on the rods of hydraulic pistons 73, 83 in cylinders 74, 84 carried by the frame 26, the securing screws 121, 125 being in elongated holes so that the racks 71, 81 may be disengaged from the pinions for the preliminary manual adjustment. The fluid pressure supply to the cylinders 74, 84 is from the pipe 64, passage 110 and a central bore and peripheral grooves in the axle 27 of the frame 26. Stops 78, 79, 88, 89 limit the movements of the racks 71, 81. The fluid pressure compresses the springs 77, 87 and brings the shoes 28, 29 away from the work 12. The screws 32, 39 are held in this position by pins or levers 90, 100 which abut against lugs' on the knobs 31, 39. The levers 90, 100 are retained in the stopping position, by spring- pressed plungers, until the pins are removed from the path of the lugs by manual displacement of the levers 90, 100. The springs 77, 87 then move the racks 71, 81 and the screws 32, 39 to bring and maintain the shoes 28, 29 against the work.

Filed: 1961-08-28
Abstract: 931,309. Printing-plates. R. C. BLACKMORE, and W. HARVEY. April 6, 1962 [Aug. 29, 1961; March 22, 1962], Nos. 31097/61 and 11084/62. Class 41. [Also in Group XVI] An electrotype printing plate is formed on a flat or curved mould e.g. by electro-deposition of copper, and the negative side of the separated formed plate is then treated with a small amount of a low-melting metal sufficient only to fill the sharp depressions, and the plate is then backed-up by a heavy plating of a metal e.g. tin/lead alloy which may also contain cadmium or antimony. As low melting alloy 50: 50 tin and lead may be used, the m.p. lying preferably 65-200  C. A lead-tin-bismuth-cadmium alloy melting at 80 C. may also be used. By this process distortion of the flat or curved plate by hot metal is largely avoided, and removal of material backing up "white areas " at intermediate processing stages is unnecessary. In examples, a laminated plastic mould mounted on flat glass sheet is silvered and plated with copper to form a shell 0.02 inch thick. The separated shell has laid on the negative side, tin/lead foil 0.005 inch thick which is heated to 200, e.g. by radiation, when sharp depressions are filled. The printing face is then protected with a coating of shellac and suspended in bath containing tin, lead and fluoboric acid, to form a plate 0.06 inch thick, and this side bonded to aluminium giving a total thickness of 0.166 inch. The low melting alloy may be applied before or after forming a curved printing plate, and then plated with lead-tin.

Filed: 1936-11-06
Abstract: 486,593. Hydraulic master cylinders. AUTOMOTIVE PRODUCTS CO., Ltd. (Hydraulic Brake Co.) Nov. 6, 1936, No. 30299. [Class 103 (i)] [Also in Group XXIX] The piston of a hydraulic master cylinder suitable for brake operation comprises relatively slidable inner and outer parts upon one of which both the operating member and return spring act whereby normally and during the return movement the parts are relatively displaced and a perforated packing cup is distorted to give communication between the reservoir and cylinder. The master cylinder 28 shown is of the type that extends into the reservoir and the piston comprises a cylindrical shell 56 within which slides a plunger 58 having a reduced forward part providing an annular passage 66, longitudinal channels 68 in the rear part and a lip 72 of the same size as the opening in the shell. The return spring 90 bears through a recessed disc 86 and a perforated flexible cup 80 on the plunger so that normally the parts are in the position shown with the piston members against a bent wire stop 78 and the cup 80 distorted and there is communication between the cylinder and reservoir through the passages 82, 66, 68. When the piston is moved forwardly to apply the brakes &c. by the usual lever engaging the plunger plate 74, the plunger is first displaced until the shoulders 64, 60 engage and the forward face of the two piston parts are in the same plane so that the communication of the cylinder with the reservoir is cut off. During the return stroke the piston parts are again displaced to the relative positions shown permitting flow of liquid through the piston. The spring 90 may bear at the discharge end of the cylinder upon a double-acting valve. The device is also shown applied to a barrel-type cylinder having a pipe connection to the reservoir adjacent the forward end of the piston, the plunger part of which in this case has at its rear part an annular passage communicating by longitudinal channels with the forward end. The relative displacement of the two piston parts is in this case limited by. a transverse pin. Specification 486,615 is referred to.
