Patent GB-820595-A (GB)
Title: Improvements relating to turbine nozzles
IPC: F01D17/16
Filed: 1957-05-30
Abstract: 820,595. Turbines. GARRETT CORPORATION. May 30, 1957 [May 31, 1956], No. 17210/57. Class 110 (3). In a turbine variable nozzle assembly comprising a ring of nozzle vanes pivoted about axis substantially parallel to that of the turbine, each vane has an operating arm extending away from the turbine axis and affording an engaging surface, the surfaces being engaged by a resilient actuating ring, the radius of the operating arms from the nozzle vane axis to engaging surface differing in such manner that only some of them of maximum radius engage the ring at atmospheric temperature. A centripetal turbine wheel 10 supported in a frame 12 is surrounded by an annular row of pivoted nozzle blades 11 in turn surrounded by a ring of stationary guide vanes 19. The vanes 11 are carried by shafts 14 mounted in bearings 13. Each shaft has a disc-like head 15 with a chordal flat 15a which co-operates with a pin 15b projecting from the frame 12 to limit the extent of rocking movement of the vanes so as to prevent them moving into the path of the wheel 10 in the event of failure of the nozzle actuating mechanism. The aerodynamic loading of the vanes 11 is such that these vanes tend to pivot into the closed position. The shafts 14 are connected by shear pins 22a to arms 22 which extend away from the turbine axis and support a nozzleactuating ring 24. The ring 24 which is of channel-section and resilient, carries pins 27 which engage slots 26 in the arms 22. To alleviate the effects of thermal expansion of the frame 12, the ledges 28 of only four of the arms, distributed uniformly about the circumference, engage the ring 24 under normal ambient temperature conditions. The ledges of the remaining arms have a clearance between them and the ring 24. The ledges 28 at positions midway between the arms which engage the ring have the greatest clearance whilst the remaining ledges are stepped progressively towards the arms which engage the ring. The arrangement is such that when the frame 12 expands during operation of the turbine, the arms 22 which engage the ring 24 deflect the ring and pull the intermediate parts of the ring inwardly towards the ledges 28. At high temperatures, the ring 24 may be forced into close proximity to all of the ledges 28. The ring 24 is actuated by a control-shaft 38 through a crank 36 and link 34 arranged so that when the nozzle vanes are near the closed position a relatively greater movement of the control shaft is required to obtain a comparable angular movement of the vanes 11. The shaft 38 may be actuated by speed, pressure or temperatureresponsive means.

Title: Improvements in Thermistor
IPC: H01L29/207
Filed: 1967-04-18
Abstract: 1,168,134. Thermistors. GENERAL ELECTRIC CO. 18 April, 1967 [19 April, 1966], No. 17693/67. Heading H1K. [Also in Division C1] A thermistor usable over a large temperature range has a body of doped cubic boron nitride bearing two ohmic contacts. The dopant may be beryllium, sulphur, selenium, silicon, germanium, or boron and may be incorporated (in the proportion of 0À001-1À0% by weight of nitride) during the lithium nitride catalysed conversion at 1500-1900 C. and a pressure of 40-55 kilobars of hexagonal boron nitride to the cubic form. 300-500Ácrystals of the cubic material are separated by hand after dissolution in aqua region of remaining hexagonal material. To make the thermistor shown a crystal 1 cleaned in strong acid and then degreased is placed in contact with degreased heat sink-lead assemblies consisting of iron-cobalt-nickel leads 4 welded to molybdenum or tungsten bodies 3 each provided with a palladium coating 2. These parts were jigged with an alumino-silicate glass preform 5 in a gas-tight furnace containing oxygen-free forming gas of low dew-point and heated to form the ohmic contacts and seal the assembly, the leads being pushed inwards during the process. An outer envelope 7 of devitrified glass is applied to protect the lead-heat sink welds. Oxide on the exposed portions of the leads is removed and the leads chromium-plated. An alternative material for the ohmic contact is palladium-nickel alloy. In general, contact material may be applied by evaporation, as a slurry, or as a pre-form. Other lead materials are tungsten, molybdenum, and the following materials which require no protective chromium coat:-platinum, palladium, and palladiumcoated molybdenum. The atmosphere used in the firing stage and which is retained within the encapsulation may instead be argon, helium, nitrogen or hydrogen, or the firing may be effected in vacuo.

Title: A process for use in the production of a semi-conductor device
IPC: H01L23/482
Filed: 1961-05-15
Abstract: 902,559. Semi-conductor devices. SIEMENS - SCHUCKERTWERKE A.G. May 15, 1961 [May 13, 1960], No. 17695/61. Class 37. In the production of a semi-conductor device the surface 12 (Fig. 2) of a body 11 of monocrystalline material is heavily doped so as to produce a layer of the opposite type. The layer is then divided by etched channels 13 (Fig. 3), and the device reheated so as to increase the depth of penetration of the doping material (Fig. 4). In a particular embodiment, N-type silicon is sealed with aluminium in an exhausted quartz vessel which is heated at a temperature of 1220-1240 C. for 30 minutes to produce the thin, strongly doped, surface layer. The device is then covered with wax which is removed in the region of the etch pit. After the production of these pits by etching the device is heated in vacuo for about 24 hours. In the arrangement shown in Fig. 5, a metallic electrode 16 is produced by alloying on a gold boron foil. A ring-shaped electrode 17 is produced in the region 14 and a further N region is produced by alloying in a gold antimony foil provided with an electrode 19. Where P-type silicon is used as the starting material phosphoros may be used as the dopant. The invention may be applied to an alloying process, e.g. a boron-containing gold foil may be alloyed to one face of a semiconductor wafer and the surface eutectic formed on cooling removed by means of aqua regia. The recrystallation layer thus exposed is divided by etching and the doping depth increased by heating.
