Title: Improvements in and relating to self-lapping driver's brake valve devices
IPC: B60T15/04
Filed: 1932-04-29
Abstract: 399,159. Fluid-pressure brakes. WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London.-(Assignees of Lynn, E. K. ; 1372, Broadway, East McKeesport, and Bush, R. J.; 340, North 1st Street, Jeannette, both in Pennsylvania, U.S.A.) April 29, 1932, No. 12403. Convention date, Oct. 16, 1931. [Class 103 (i).] A driver's brake valve has admission and release valves adapted to be actuated manually without operating the piston and spring device used for automatically returning the valve device to its lap position. The admission valve 18 which is urged towards its seat by a spring 20 is slidably mounted in a liner 17 and is provided with a socket to receive one end of an operating rod 48 pivoted at 47 to a floating double lever 41 pivoted at 42 to a slidable plunger 43. The other ends of the levers 41 carry a roller 46 adapted to engage the stem 35 of the release valve 32. This valve is housed in a piston 25 and is urged from its seat by a spring 38 lighter than the spring 20, outward movement being limited by a collar 36 engaging a stop plate 40. The piston 25 which is subject to the pressure being controlled is acted on by an adjustable spring 29 stronger than either of the springs 20, 38 and has a rod slidably mounted in the spring abutment 22. The plunger 43 is moved by a cam 53 on a rotatable shaft adapted to be operated by a removable handle 55. In the position shown the control chamber 11 is connected to atmosphere through valve 32 and exhaust passages 34, 28. On rotating the cam to depress the plunger, the exhaust valve first closes and then the admission valve opens. As the pressure builds up in the chamber 11 the piston is moved back against the action of' the spring 29 allowing the spring 20 to close the admission valve when the desired pressure has been reached. When the cam is turned to depress fully the plunger 43, the admission valve is not closed even when the piston has been moved until the piston-rod contacts with an adjustable stop 24 so that the maximum pressure of the supply is built up in the chamber 11.

The polishing agent may be colloidal silica, an alkali metal aluminosilicate, dicalcium orthophosphate dihydrate, or calcium carbonate. The composition may also include sodium saccharine, calcium chloride and/or oil of peppermint. The di(chlorophenyl biguanido) hexane salt may be added to the carboxyalkyl cellulose salt either simultaneously with or after the surface active agent.

Abstract: 1317583 Semi-conductor devices GENERAL ELECTRIC CO 19 March 1970 [25 April 1969] 13283/70 Heading H1K Contact is made to a silicon wafer by dedopisiting thereon a refractory metal e.g. molybdenum or tungsten, containing one or more dopants and heating to diffuse in the dopants to give a surface concentration of at least 10<SP>19</SP> atoms/cc. without alloying. In a typical embodiment molybdenum containing 3 atomic per cent of boron is deposited, preferably by triode sputtering, on a multi-apertured layer of silicon dioxide, nitride or oxynitride or alumina formed by conventional techniques on on a 111 orientated N type silicon wafer, and optionally coated with silica prior to heating at about 1050 C in an inert atmosphere to form a PN junction 1Á deep by boron diffusion. The molybdenum may be pattern-etched before or after the diffusion and the wafer ultimately subdivided into single junction elements which be bonded to headers with gold-antimony solder. In a modification the back contact may consist of a deposited molybdenum-phosphorus layer from which phosphorus diffuses during formation of the PN junctions. A series of junction-isolated resistors can be formed by diffusion from boron doped molybdenum strips which extend across an aperture in an oxide layer on N type silicon and are coated with silica. This silica and parts of the molybdenum strips are then removed by etching to leave P type tracks contacted at their ends by the remaining molybdenum. Lateral transistors with self-registering interdigital electrodes may be formed by a similar process but without removal of the molybdenum. To provide low resistance contacts on a PN junction wafer the opposed P and N faces are completely coated with molybdenum containing boron and phosphorus respectively. After diffusion the wafer is bevelled and the bevel coated with silicone rubber to increase the breakdown voltage. In the manufacture of integrated circuits simultaneous diffusion is effected from mutually spaced patterns of molybdenum containing donors and acceptors respectively via apertures in oxide masking. A bipolar transistor is formed by simultaneous diffusion of a fast diffusing acceptor and slower diffusing donor e.g., boron and antimony into a mask exposed part of a P type base contact layer on an N type silicon wafer. Alternatively after diffusing through oxide masking from molybdenum-boron to form a base region in an N-type silicon wafer the molybdenum is removed save for a U-shaped electrode portion, silica deposited overall and removed from an area within the U and a phosphorus-containing molybdenum layer deposited and heated to form the emitter zone and its contact.
