Title: Improvements in and relating to thermal control systems
IPC: H01L29/00
Filed: 1953-01-19
Abstract: 737,324. Automatic temperature control systems. GENERAL ELECTRIC CO. Jan. 19, 1953 [Jan. 17, 1952], No. 1495/53. Class 38 (4). [Also in Group XXXVI] In Fig. 2, thermocouple junctions are formed by attaching copper wires 25, 26 by silver or lead solder at 23, 24 to a rod 22 of P-type germanium adjustably mounted on a ceramic support' 27 so that junction 23 is nearer than junction 24 to an electric heater element 28. If the temperature produced by heater 28 rises above a value determined by the room temperature resistivity of the germanium, the thermocouple polarity reverses so that it is effective through a rectifier 31 to energize a relay 35 and switch off the supply to heater 28 until the temperature falls again. In Fig. 4, a Hall plate 41 of P-type germanium, held between insulating plates 43, 44 by a permanent magnet 42, is supplied from a D.C. source 49 and is responsive to the temperature of an electric heater 28. If the temperature produced by heater 28 rises above a predetermined value the Hall plate output polarity applied to the grid-cathode circuit of a triode valve 52 reverses so that a relay 35 is energized to switch off the supply to heater 28. In Fig. 6 a rectifier is formed by a wafer 56 of P-type germanium and a contact wire 63 of platinum or platinum alloy mounted on metal plugs 59, 60 in an insulating cylinder 57 having a window 58 so that the rectifier is responsive to the temperature of an electric heater 28. If the temperature produced by heater 28 rises above a predetermined value the direction of conduction of the rectifier reverses to permit a D.C. source 34 to energize a relay 35 to switch off the supply to heater 28.

Abstract: 101,820. Reuss, E., and Roberts, V. Feb. 3, 1916. Tanks and cisterns.-In apparatus for electrolyzing brine for use particularly at sea, a supply tank, electrolyzer, and storage tank are suspended so as to avoid irregularities in the flow of electrolyte, and agitation of the product. In one arrangement, the electrolyzer a, Fig. 1, is mounted o n gimbals. Pivots h are attached to plates i below the rim b of the earthenware electrolyzer vessel, and are provided with lugs to hold U-shaped bolts k bracing the vessel. Tubulures c at the ends of the electrolyzer supply and remove liquid, and mav also serve as pivots; it one tubulure is damaged, the other serves for removal and a loose feed-pipe is used. Bearings for the gimbal d are carried by standards f on a table g having an aperture s bridged by a bar r from which the storage tank q is suspended. A flexible tube o, leading to this tank from the electroylzer, is partly coiled on the table to relieve the electrolyzer of part of its weight. In another arrangement, the electrolyzer is hung by means of links, ropes, or chains engaging the tubulures c, from a yoke provided with a hook suspended by a universal joint. In order to level or tilt the electrolyzer, the hook is adjusted in a slot along the yoke, the chains or links are adjusted in length, or weights are hung from one end to the yoke. Fig. 6 shows the tubulures 14 situated on the long side of the electrolyzer and connected by passages 13 to the ends of the electrolyzer, to ensure circulation. Here the tank is braced by straight bolts i and pairs of curved bars i<1>. Corner pieces connected by bolts along all sides may also be used, or the tank may be enclosed in a case. A supply tank 15, Fig. 4, of barrel or other shape, may be fitted with an internal ring 17 bearing eyes 21 for suspension from a ring 23 on a bar 24; or other forms of universal-joint suspension may be adopted. Interference with the action of a ball valve 16 by rocking of the ship is thus avoided.

Title: Improvements in or relating to fuzes for projectiles
IPC: F42C13/06
Filed: 1939-01-18
Abstract: 538,049. Projectile fuzes. FISHER, E. G. Jan. 18, 1939, No. 1804. [Class 9 (i)] [Also in Group XXXVIII] A fuze for anti-aircraft shells comprises a microphone controlling the actuation of a spring striker, whereby the shell is detonated when the microphone receives sound waves from the engine of an enemy aircraft, the fuze having first been armed by a wind-vane device after a predetermined time in flight. If the microphone circuit is not energized, the wind-vane device subsequently causes the actuation of the striker by mechanical means. The microphone 5 is located in the nose-piece 2 of the fuze, which is rotatable by wind-vanes 4 relatively to the fuze body 1. Extensible leads 8 from the microphone are connected to contact rings 7a, 7b on a nut 7 mounted on a screwed sleeve 6 carried on a frictionally-held contact plate 9. When, by the rotation of the nose 2, the nut 7 is caused to travel down the screw 6, it is brought into contact, after a predetermined time, with the contact rings 9a, 9b of the plate 9 and the microphone is thereby connected by brushes 10 and leads 11 to a source of current 12. The circuit includes an electro-magnet 20 and a make-and-break device 21a-21c. The electromagnet, when energized, lifts a spring-controlled striker 18 and compresses the striker spring 17. When the enlarged tail 15 of the striker has passed the weighted arm 21b of the make-and-break device, the latter is free to fall and open the circuit. The electromagnet is thus cut out and the striker is released and fires the detonator 19. If, after the nut 7 has made contact with the plate 9, no sound-waves are picked up by the microphone, continued rotation of the nose 2 overcomes the frictionlock on the plate 9 and the screwed sleeve 6 is rotated. This causes the downwards projection of a screwed rod 13, which is lightly restrained from rotation until a collar 13b thereon reaches the end 6a of the internallythreaded portion of the bore in the sleeve, whereafter the rod 13 rotates with the sleeve. The rod has a quick-threaded enlarged end 13a which enters a threaded bore 14 in the striker 18 and lifts the striker until the spring 17 sets up such a resistance as to cause the rod 13 to break and thus to release the striker and Explode the shell. The striker point is normally separated from the detonator by a pivoted shutter 22a. Retraction of the striker permits the shutter to be tilted out of the striker path.

Title: Improvements in or relating to the manufacture of forged hollow bodies
IPC: B21K1/00
Filed: 1937-01-22
Abstract: 488,378. Projectiles; casting- machines; dies. JONES, E. F. Jan. 22, 1937, No. 1925. [Classes 83 (i), 83 (ii), and 83 (iv)] Shells for bombs and projectiles are forged from liquid or semi-liquid steel 11, Fig. 1, introduced into a mould 12 by forcing a plunger 16 into the metal. The pressure is maintained by a sleeve 17 with steel washer 18 which is of U-shaped cross-section. The washer has a conical outer edge 19 to rest on the top of the mould and a doubled inner edge 22 to form a seal and prevent " flash." A loose ejector piece 13 is placed in the bottom of the mould. After the shell 11 has set and before sufficient contracting takes place to produce incipient cracking, the plunger is raised while the shell is held back by the sleeve 17. Thereupon, the sleeve 17 is withdrawn and the mould and shell moves along rails 15, Fig. 9, to a position at which an ejector is applied through an aperture 24. The shell when ejected is still at a bright forging heat. It may be produced with thicker walls for subsequent reduction thereby avoiding the risk that their walls solidify before the nose portion. In a subsequent operation the shell 11 is reduced to the form shown in Fig. 4, after which a mandrel 126 is placed in the shell and abuts the inside bottom part being maintained concentric thereby. A pressure sleeve 127 further alters the shape to that indicated by chain lines 128. Various other forms of shell are produced in the same manner. To ensure that the quantity of metal for each forging is constant and to expedite the process, a ladle 50 with closure 66 pours metal into a tilting crucible 52 having a spout 53 and nozzle 54. The crucible and pouring spout are surrounded by a refractory case. A gas or oil burner 59 is provided within the refractory casing to heat the crucible. Pouring ceases when the nozzle 54 is raised to a level with the metal in the orucible. The aperture 63 in the roof of the casing of the crucible is sufficiently large to allow of pouring from the ladle in all positions of the crucible. Specifications 9134/88, [Class 83], 381,790, 402,096, 408,013, 412,218, and 472,654. are referred to.
