Title: Improvements in or relating to flexible composite materials and a process for their manufacture
Inventor: PHILLIPS LESLIE NATHAN
Filed: 1968-05-07
Abstract: 1,244,984. Partially cured material. AVIATION SUPPLY, MINISTER OF. 30 May, 1969 [7 May, 1968], No. 21472/68. Heading D1R. A flexible composite material is formed by impregnating lengths of filamentary reinforcement material with uncured resin, partially pre-curing the resin, and applying heat and pressure to soften the resin and to effect further pre-cure, but not final cure, to spread the filaments and to reduce the material to the required thickness. The resin may comprise epoxy, polyester, phenolic or modified phenolic, polyimide, Friedel-Crafts or furane type with solvent and catalyst. Pressure and heat may be applied by heated platens, rollers in a temperature controlled atmosphere and/or heated rollers, or hand irons. The filamentary mat may have random orientation or may be arranged in pattern before impregnation, e.g. in single parallel array with or without a minor proportion normal thereto, or in at least two sets with the filaments in each set parallel to each other and with one set angularly displaced, e.g. at 0 and 90‹ or each at 45‹ to the length of the material. An example uses carbon filaments with an equal weight of a solution containing 60 gms. hot-setting epoxy resin in 90 gms. acetone with 2.4 g. borontrifluoride amine complex as catalyst. It is pre-cured at 100‹C for 30 mins., heated and pressed several times at 60-80‹C. and 60-80 lbs. s.i. for 30 secs., and then heated at 100‹C. for 30 mins. to further cure the resin to a stable condition. Final curing is affected by further heating.

Title: Methods of manufacturing semiconductor devices
IPC: H01L21/203
Filed: 1970-05-05
Abstract: 1308013 Semiconductor devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 5 May 1970 [8 May 1969] 21578/70 Heading H1K A method of manufacturing a semiconductor device in an integrated circuit using a two-stage epitaxial process comprises forming in one surface of a semiconductor substrate a region having a high concentration of an impurity of one conductivity type and depositing epitaxially on that surface a layer of the one conductivity type in two stages, the deposition process being interrupted between the first and second stages while the apparatus used for the epitaxial deposition is cleared of all traces of the impurity so that the second stage takes place in apparatus free from the impurity. Alternatively a different apparatus may be used for the second stage. The method is used in the formation of lateral transistors, wherein on a P-type substrate 1 P + type region 3 to form isolation regions and an N-type region 4 to form a buried layer are deposited. During the first stage of epitaxial growth N-type layer 5 is grown, the impurities from regions 3 and 4 diffusing up through this layer. The epitaxial growth is then stopped and the apparatus cleaned, and the surface of the epitaxial layer is etched. During the subsequent stage of epitaxial growth N-type layer 7 is grown free of the impurities from region 4. By diffusion into the free surface, emitter region 9 and collector region 10 are formed in this second stage layer 7, and P+ type impurity is diffused through to join with regions 3 so that they extend right through the epitaxial layers to form isolation regions. Arsenic and boron are used as the impurities.

Title: Improvements in or relating to liquid-blast electric circuit interrupters
IPC: H01H33/98
Filed: 1945-08-31
Abstract: 599,318. Liquid-blast switches. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Aug. 31, 1945, No. 22460. Convention date, Aug. 31, 1944. [Class 38(v)] A liquid-blast circuit-breaker in which a pressure-generating arc forces extinguishing fluid through an interrupting arc has two mechanically driven pistons to supplement the normal flow, one jetting fluid into the pressure generating arc and the other which may be stalled by back-pressure during high current interruption, but subsequently flushes out the interrupting arc. The circuitbreaker comprises two arc - extinguishing units, of laminated construction mounted on the terminal stems of insulators in an oil tank, Fig. 1 (not shown), each housing the pressure-generating contact 16, intermediate contact 17, and an interrupting contact 47, connected through isolating contact 62 by a bridging piece 12 to the other unit. A spring-loaded insulating rod 31 abutting on the bridgepiece carries a pin 29 engaging one arm 27 of a forked lever, whose other arm engages a pin 22 to impart linear motion to the pressure-contact 16, along its guide pin 20. The rod 31 also drives the piston 37 to force oil through passages 41 into the pressurearc chamber when the breaker is opened. A vent passage from the top of the pistonchamber into the unit equalises the arcpressure on both sides of piston 37 so that no extra force is required to open the contacts with high arcing currents. The other spring-loaded piston 49 is slidably mounted on the interrupting-contact 47 and vented on its upper side to the tank so that on high currents it is held up by the internal pressure but subsequently forces oil through passages 55, 45 to the interrupting arc. Check valves 56, 57 ensure a supply of clean oil being drawn into the arcing unit from the tank when the circuit-breaker is reclosed. Specification 578,422 is referred to. The Specification as open 'to inspection under Sect. 91 also refers to Specification 600,733. This reference does not appear in the Specification as accepted.

Abstract: 1,073,551. Semi-conductor devices. WESTINGHOUSE ELECTRIC CORPORATION. May 28, 1965 [July 2, 1964], No. 22769/65. Heading H1K. In making an integrated circuit structure comprising a substrate of one conductivity type with a surface layer of the opposite type divided into isolated areas by heavily doped walls of the one conductivity type formed by diffusion of impurities through the layer to the substrate, one region of a PN diode is formed within one of the areas to be isolated in the diffusion process used to form the walls. Such a structure, incorporating also a transistor, shown in Fig. 2, is made as follows. N+ inclusions are formed by diffusing phosphorus into the surface of a 20 ohm. cm. P-type silicon substrate and are subsequently buried beneath an epitaxially grown N-type layer. Boron is next diffused into this layer to form dividing walls 79 and the P + diode region 60. Rings of N + material joining the N+ inclusions to the surface are formed by phosphorus diffusion, after which the transistor base 54 is formed. Finally the N+ surface layer 58 of the diode and transistor emitter 52 are produced by phosphorus diffusion. Subsequently the surface of the layer is coated with a passivating oxide layer, gold, copper, iron or manganese is diffused throughout the silicon body from a vapour deposited layer on the opposite face and electrodes attached as shown to the various regions. In a modified structure (Fig. 5, not shown) the N+ surface layer of the diode is isolated from the N+ region.
