Title: Improvements in and relating to fluid regulating valves
IPC: F16K43/00
Filed: 1960-12-06
Abstract: 916,815. Valves. COMPAGNIE DES FREINS ET SIGNAUX WESTINGHOUSE. Dec. 6, 1960 [Dec. 9, 1959], No. 41940/60. Class 135. A valve comprises a closure member 5 coacting with a seat 4 between the inlet 2 and outlet 3, a screw-threaded stem 6 coacting with an internally-threaded sleeve 7 which is screwed into the housing 1, a sealing ring 12 carried in an annular groove 11 in the stem and coacting with a smooth portion of the sleeve 7, and a handle 15 which is freely rotatable in a collar 14 screwed to the outside of the sleeve 7 and has a square recess engaging a similarly shaped end of the stem 6, the arrangement being such that after removal of the collar 14 and handle 15 the stem can be screwed outwardly beyond the normal fully-open position of the valve to enable the sealing ring 12 to be removed and replaced. During this operation sealing is effected by engagement of the upper surface of the valve member with the inner end of the sleeve 7. A screw 18, adjustable in the end of the stem, constitutes a stop limiting the normal opening movement of the valve. The closure member has two frustoconical portions 27, 29 interconnected by a cylindrical part 28. The seat is sharp-edged at 24, and below a cylindrical part 25 a recess 26 is formed to prevent distortion of the seat by a conduit screwed into the outlet 3. In a modification, the inlet and outlet are in axial alignment and the stop screw 18 is omitted, whilst in a further modification, the handle 15 and collar 14 are omitted and the stem, which terminates just above the sealing ring 12, has a screw-driver slot, and a cap is screwed over the sleeve 7 to enclose the end of the stem.

Three preferred embodiments are described in detail, each differing in the form and disposition of the cutter jibs, discs, and expanding means forming the cutter head of the machine. In the embodiment shown the expander means consists of free pistons 50 in cylinder blocks 25 ram-slid in the frame of a vertical bank of cutter jibs 20 having cutter drums 23 positioned at the leading ends. Clean up ploughs 4, 5 are provided at the rear of the head.

Title: Ohmic contacts and interconnection system for integrated circuits

Abstract: 1,200,656. Semi-conductor devices. TEXAS INSTRUMENTS Inc. 15 Sept., 1967 [30 Dec., 1966], No. 42215/67. Heading H1K. [Also in Division C7. In an integrated circuit based on a semiconductor wafer with a coating of insulation bearing more than one level of interconnections the lowest interconnections each comprise a layer of molybdenum in ohmic contact with a region of the semi-conductor wafer and overlying layers successively of gold, a gold-vanadium mixture, and vanadium oxide. In the described embodiment, in which the first level interconnections form internal connections of a sub-circuit and second level interconnections interconnect the sub-circuits, the insulation coating on the silicon wafer is of silicon oxide or nitride. The molybdenum layer, 2000 thick, is formed by sputtering, evaporation or sublimation and its contact to silicon may be improved by a preliminary dopant diffusion into the contact areas or by coating them with a layer of aluminium or platinum silicide. The gold layer which may contain platinum to improve its adhesion is then deposited to a thickness of 5000, followed by a layer of vanadium. After etch-forming the interconnections from these layers using photoresist techniques the assembly is heated to 450 C. for an hour to surface oxidize the tantalum and cause it to partially dissolve in the gold. The extent to which solution occurs can be controlled by the temperature and oxygen supply or by providing a diffusion barrier of molybdenum, which oxidizes during the heating, between the gold and vanadium. An insulating layer 6000 thick, which may consist of silicon, nitride, alumina, tantalum oxide or organic resins but is preferably silicon oxide formed by reaction of silane and oxygen is next deposited and etching of this and of the underlying layers of vanadium oxide and vanadium-gold effected to expose the gold at desired interconnection points. The above processes are repeated to form higher levels of interconnections save that the vanadium deposition and subsequent steps are omitted in the uppermost level to permit bonding thereto by thermocompression of gold wires forming external connections, or face bonding to a ceramic substrate. Alternatively the top level of interconnections consist of gold on vanadium.

Abstract: 1488712 Detecting malignant and non- malignant diseases in an organism SPITALUL CLINIC FILANTROPIA 2 Oct 1974 42838/74 Heading G1A In a system for detecting malignant neoplasias and other non-malignant diseases in an organism the whole infrared spectrum emitted by a "thermic spot" of an investigated organism are analyzed, and the nature of the disease is diagnosed by the shape of the spectral curve obtained, by its width, and its range of shifting as compared to the spectral curve of a normal similar tissue. In an apparatus for carrying out the above a variable wavelength mono-chromator 1 receives the radiation 3 emitted by the tissue 2 and the resulting mono-chromatic infrared beam is received by a transducer 5 (thermo element, bolometer or pneumatic receptor). The electrical output signal is fed via an amplifier 7 to a strip recorder device 8 that is advanced in synchronism with the change in wavelength of the mono-chromator. The variable wavelength mono-chromator 1 and the strip recorder may be coupled together by self synchronizers.
