Title: Improvements in or relating to the surface hardening of metallic objects
IPC: C21D1/06
Filed: 1934-08-31
Abstract: 428,995. Heat - treating. LINDE AIR PRODUCTS CO., 30, East 42nd Street, New York, U.S.A.-(Assignees of Kinzel, A. B.) Aug. 31, 1934, No. 25139. Convention date, Sept. 16, 1933. [Class 72] Metallic objects are heat-treated either by reciprocating a source of heat rapidly to and fro over the object which is fixed and when the latter has been heated to the required temperature, shutting off the source of heat and then cooling, or by keeping the source of heat fixed and reciprocating the body under this source of heat. In the first method, a blow pipe P and a cooling nozzle D are mounted on the carriage C of a lathe L capable of moving the carriage back and forward over the object B. The pipe P and nozzle D are supported by a block 10 attached to the slide rest 11 by a crank 13 operating the rest 11 by a screw. The blow pipe P comprises a plurality of nozzles 19 mounted at the end of a stem 20 connected at its upper end to an oxygen pipe 21 and acetylene pipe 22. When the object has been heated to the required temperature, the valve 24 is closed and the valve 26 opened, thus shutting off the heat source and allowing cooling fluid to flow to the nozzle D. In the second form, the blowpipe and nozzle are fixed and the object is supported on a carriage which is reciprocated. In a third form, a circular object is mounted in a lathe and rotated, the blowpipe nozzle being reciprocated along the rotating object and when the source of heat has been shut off reciprocating the cooling jet along the heated surfaces.

Title: Improvements in or relating to means for ejecting missiles from under water vessels or other submerged installations
Inventor: WOSAK ROBERT
IPC: B63G8/32
Filed: 1953-09-11
Abstract: 791,310. Launching torpedoes. GENERAL DYNAMICS CORPORATION. Sept. 11, 1953, No. 25166/56. Class 9(2) A balanced system for ejecting missiles from an installation on a submarine or from other similar installations submerged under the surface of the sea comprises a missile ejecting tube whose nozzle end is submerged below the surface of the sea, a water cylinder, a passageway connecting the cylinder with the sea so that the hydraulic pressure from the sea is substantially the same in the water cylinder as it is at the muzzle end, means defining a conduit connecting the water cylinder and the ejection tube for the passage of water from the cylinder into the tube, a piston and rod mounted for reciprocation in the water cylinder, which piston on its stroke from the retracted position forces water ahead of it from the cylinder into the tube for ejecting a missile while drawing water behind it into the cylinder through the passageway, and means including water ports in the cylinder to provide escape from the cylinder into the tube for water moving behind the piston whereby the energy built up in the mass of water moving behind the piston is dissipated through the tube when the piston is brought to rest at the end of its stroke from the retracted position. Referring to Fig. 1 the water cylinder 11 communicates through ports 23 with a plenum chamber 24 which can be made to communicate with one of the torpedo tubes by opening a slide valve 31 and thus exposing ports 30 in the tube. The piston 12 in the water cylinder is operated by a piston 14 in a cylinder 13 which can be supplied with air under pressure and the space behind the piston 12 forms a passageway 18 to the sea. The muzzle door of the tube and the slide valve 31 can be opened together by admitting compressed air to a cylinder 59: after these have been opened the torpedo can be ejected'by operating the piston 12 so that water is forced into the torpedo tube. When the piston 12 nears the end of its stroke the water behind the piston can escape into the chamber 24 through ports 23, and when the piston is retracted after its stroke water is drawn in from the sea through the torpedo tube to refill the cylinder 11. The muzzle door of the tube is then closed and the water in the tube is drained into a water tank 81 and air admitted to the tube through a pipe 73. After the tube has been re-loaded sea water is admitted to the tube through pipes 79 and 75, air being expelled through the pipe 73, and the tube is ready to fire again. The piston 12 is provided with a bumper 124, which engages a resilient stop 125 at the forward end of its stroke, and with a dashpot piston 38 which enters a dash-pot cup 36 at the rear end of its stroke.

Title: Improvements in or relating to a method of manufacturing semi-conductor devices
IPC: H01L21/00
Filed: 1960-07-20
Abstract: 879,416. Semi-conductor devices. TELEFUNKEN G.m.b.H. July 20, 1960 [July 23, 1959], No.. 25220/60. Drawings to Specification. Class 37. A method of making a semi-conductor device includes the steps of forming a convex-surfaced alloying pellet using a punch with a convex punching face, applying the convex face of the pellet to a semiconductor body and subsequently alloying it thereto. The convex face of the pellet preferably forms part of a sphere with a radius five times that of the punch which is preferably made of tool steel with a polished punching face. The pellet is pressed against the semi-conductor by the punch which is then withdrawn. Its form enables alloying to proceed from the centre outwards so that gas is not trapped and where alloying is effected in reducing gas allows this to come into contact with substantially the entire surface of the pellet to remove oxides therefrom.

Title: Improvements in timing mechanism
IPC: G04F3/02
Filed: 1960-07-20
Abstract: 940,220. Timing mechanisms. G. Q. PARACHUTE CO. Ltd., and A. E. F. THOMAS. Oct. 20,1961 [July 20, 1960], No. 25276/60. Heading G3T. [Also in Division B7] A safety harness release timing mechanism for the ejection seat of an aircraft has two different delay periods. A rack 19 is urged to the left by a lever 30, 32 acted on by a spring 11 but is normally locked by a locking and interceptor pin assembly 39, 42. When the interceptor pin is removed on election of the seat, the rack 19 is freed to move leftwards at a rate determined by an escapement 26, 27 driven by gearing 21-25. The rate of rotation of the escape wheel is determined by the inertia of the pivoted anchor 27. The lever 30, 32 has an arm 34 connected by a link 35 to the arm 36 of a double-armed lever the other arm 38 of which normally latches a pair of hammers 3 loaded by springs 11, 16. The arm 34 rotates counter-clockwise as the rack 19 moves and at the end of the delay period releases the latch arm 38 from the hammers 3 which are actuated to strike pins 10 which fire cartridges 18 and cause a piston 6 to move to the left and effect release of the hammers from the ejected aircraft seat. If, before release of the rack 19 a bell crank lever 46 is rocked counter-clockwise e.g. by means responsive to aircraft speed, a second anchor 45 is brought into engagement with the escape wheel 26 to reduce its rate of rotation and so produce a longer delay period before harness release. The anchor 45 is weighted by a cylindrical element 47.
