Title: Improvements in dyeing artificial fibres
IPC: D06P1/00
Filed: 1956-04-26
Abstract: Artificial fibres of cellulose acetate, polyacrylonitrile, polyamides, polyurethanes or polyesters are dyed with an aqueous dispersion of a 1-aminobenzophenone-sulphone of the formula: <FORM:0792396/IV (b)/1> in which R and R1 represent hydrogen or identical or different alkyl, hydroxyalkyl, cycloalkyl, aralkyl or aryl radicals or are members of a common saturated ring, Z represents hydrogen, a methyl or ethyl, an acyl, a carboxylic acid or an ester group, and A and B represent hydrogen, methyl or ethyl or alkoxy or nitro groups or halogen atoms.  When the dyestuff contains a carboxylic acid group the fibres are preferably pretreated with an animalizing agent, e.g. the reaction product of 2 mols. acrylonitrile with 1 mol. p,p1-diamino-dicyclohexylmethane.  Numerous examples are given.  The dyes may be made by oxidizing 1-halogenthioxanthones to the 1-halogenthioxanthone-sulphones and then reacting the halogen atom with ammonia or with a primary or secondary amine. Alternatively, they may be made by nitrating 2-alkylbenzophenone-sulphone and converting the resultant 1-nitro-2-alkylbenzophenone-sulphone into the corresponding isoxazole derivative followed by reduction or by reaction with water or with an organic hydroxy compound.  Specifications 781,558, 783,067 and 790,587 are referred to.

Title: Improvements in or relating to carburettors for internal combustion engines
IPC: F02M1/00
Filed: 1949-05-14
Abstract: 693,962. Spray carburetters. McCANDLESS, R. Aug. 11, 1950 [May 14, 1949], No. 12922/49. Class 7 (iii). The fuel supply to a float chamber 1 is controlled by a sleeve or piston 10 which cooperates with ports 8 in the wall of a tubular liner 6 pressed into a central bore 7 of the float chamber cover. When the fuel drops below a predetermined level the ports are uncovered and the fuel enters through a bore 12 of the sleeve and ports 15 at its lower end. The crosssectional area of the bore 12 is greater than the total area of the port or ports 8 to prevent the bore running full. The ports 15 are of total area greater than the total area of the port or ports 8. The bore is closed at the bottom by a foot 13 which forms a bearing resting on and operated directly by the float 14. When the sleeve masks the ports 8 the lower end of the liner masks the ports 15. The sleeve slides in the bore with minimum clearance and the upper end of the sleeve has a sharp edge which reduces the risk of the valve sticking due to dirt. Instead of an annular groove 9 in the cover 4 an annular groove may be formed in the outer surface of the liner 6. The outer surface of the sleeve 10 may be relieved between its ends. In a modification the piston has a reduced portion between its ends communicating constantly with a port or ports in the cylinder wall leading to the float chamber. When the fuel level drops a second port or set of ports is uncovered and fuel flows to the float chamber.

Title: Method of producing talking motion picture film and apparatus used therefor
IPC: G03B31/00
Filed: 1925-05-23
Abstract: 235,178. De Forest Phonofilms, Ltd., (Assignees of Forest, L. de). June 7, 1924, [Convention date]. Records, combined phonograph and kinematograph; combined working of soundrecording apparatus with kinematographs. -Relates to the method of producing combined sound record and kinematograph films by first preparing the picture film, projecting it on a screen and at the same time making a photographic sound record in appropriate relationship with the projected pictures, and finally printing the sound record negative and the picture negative upon the same film. According to the invention, the sound-recording camera is electrically synchronised with the picture-projection machine. For this purpose, the arrangement shown in Fig. 2 may be adopted. A motor 23, which is geared by wheels 25, 26 to the recording apparatus 21, drives a three-phase generator 22. This supplies current to a motor 27, which is geared to the projector 20 and consequently drives it at the same speed as that of the machine 21. Instead of using this arrangement, simple synchronous motors, fed from the same current supply, may be employed to drive the two machines 20, 21. For effecting the simultaneous printing of the sound record negative film 7 and the kinematograph negative film 8 upon a sensitized film 9 to form thereon a positive combined record, the arrangement shown in Fig. 1, and described in Specification 235,179, may be used. All the films are fed together past lamp casings 10, 11, which lamps respectively print the sound and picture records upon the film 9. The casings 10, 11 are separated by a distance equal to the distance between the optical sound-reproducer element and the picture-projector element in the combined reproducing-apparatus.

Title: Ohmic contact and multi-level interconnection system for integrated circuits
Inventor: CUNNINGHAM JAMES ALAN
IPC: H01L23/29
Filed: 1967-09-15
Abstract: 1,203,087. Integrated circuits. TEXAS INSTRUMENTS Inc. 15 Sept., 1967 [30 Dec., 1966], No. 13609/70. Divided out of 1,203,086. Heading H1K.. [Also in Division C7] In an integrated circuit comprising a passivated semi-conductor wafer with a plurality of circuit elements at one surface joined by first level interconnections lying on the passivation layer, one or more further levels of interconnections insulated from the first level are provided. The connections of each level include a layer of molybdenum, titanium, tantalum, rhodium, cobalt, nickel or aluminium, and the uppermost level has an overlayer of gold. In a typical example a silicon wafer containing a matrix of groups of circuit elements formed by diffusion and/or epitaxial deposition steps has a genetic oxide passivating layer. After aperturing this at desired contact areas a 20,000 A layer of molybdenum is deposited overall by sputtering, sublimation, or preferably the evaporation technique described in Specification 1,104,504 and pattern-etched to form the first level of interconnections. Then insulation such as silicon nitride, alumina, tantalum oxide, organic material or preferably silica is deposited e.g. by R.F. sputtering to a thickness of 10,000 A and etched to expose points to be joined to a second level of interconnections. Finally this second level is formed by depositing first 1200 A of molybdenum and then 7500 A of gold and pattern-etching. Normally the first level of interconnections are internal to one group of elements while the upper level interconnects the groups and has gold terminal wires bonded to it. In a modification, in forming the first level interconnections, gold is deposited over the molybdenum and after pattern-etching is removed save at the points of connection to the upper level. Then the exposed surface of the molybdenum is oxidized by briefly heating in oxygen before the inter-level insulation is deposited. In all cases ohmic contact to the semi-conductor surface is improved by diffusing impurities or forming deposits of aluminium or platinum silicide in the contact holes before depositing the molybdenum. The gold and molybdenum may contain adhesion improving additives (e.g. platinum in gold).

Title: Manufacture of fibre reinforced composites
IPC: B29C48/15
Filed: 1973-03-21
Abstract: 1463293 Continuously moulding constant or variable section articles NATIONAL RESEARCH DEVELOPMENT CORP 19 March 1974 [21 March 1973] 13664/73 Heading B5A [Also in Divisions B8 and A6] An apparatus for use in the production of elongate fibre-reinforced articles comprises a shaping aperture defined by the surfaces of two circumferentially co-operating rolls, means upstream of the aperture for bathing continuous fibre reinforcement in a bonding material, feed means downstream of the aperture for pulling reinforcement through the aperture, and independent means for rotating the rolls to vary the aperture dimension. Oppositely rotating .rolls 8, Fig. 1, having peripheral grooves of varying depth, and reciprocating, tapered mandrel 9 define an annular aperture, Fig. 2, of cyclically varying size. Continuous strands and acid-etched aluminium foils 6 are drawn through resin bath 3, distributer plate 5 and the aperture by driven rolls 1 to form a succession of tapered, hollow articles 11 of constant wall thickness, e.g. golf club shafts. The mandrel is forwarded by roll driven pinion 103 whose smooth section 106 allows hydraulic or pneumatic jack 105 to return the mandrel quickly. The mandrel may be moved by other mechanical, hydraulic or electromechanical means. The mandrel is heated by radiant oven 114, and the rolls by electric elements 110, 112. The emerging articles 11 may be wrapped in heat shrinkable cellophane to provide a bonding pressure, cut by circular saw 116, and then part-cured by heat. The mandrel may be replaced by continuously fed, connected, preformed cores. Only one roll may be grooved. The aperture formed by the rolls may be symmetrical about a plane containing the aperture axis and lying perpendicular to a plane containing the roll axes. The aperture may be of any shape, and may be used with a similarly-shaped mandrel, e.g. of triangular shape, Fig. 3. The depth of the or each groove may increase at a constant rate, or the or each groove may be stepped. Upper roll 8 may be mechanically braked to provide an annular aperture of constant size to provide articles of constant section. The mandrel may be omitted. The fibres, e.g. of glass, carbon, boron or polypropylene, form a composite material with a thermosetting resin, e.g. a polyester or an epoxy, or with a thermoplastic resin, e.g. a polyimide. The composite forms one or more layers in the article providing the principal flexoral stiffness. Other layers provide a means of transmitting shear. Shear stiffness may be provided by winding fibres from bobbins rotating about the mandrel upstream of the aperture.

Abstract: 1,033,040. Valves. BENDIX CORPORATION. March 31, 1965 [April 6, 1964], No. 13697/65. Heading F2V. A valve has an inlet 44, an outlet 46 to aircraft de-icer ports, and an exhaust port 42. With the parts in the positions shown pressure air from inlet 44 passes through ports 86 in a valve stem 62 and is discharged to exhaust via a jet 84 in valve closure-member 54 and evacuates air from the boots connected to the outlet 46 since the latter is open to the exhaust port 42 because member 54 is coacting with an upper seat 56. A diaphragm 72 connected to the stem 62 is subjected to atmospheric pressure on both sides because a passage 92 from the inlet 44 is closed by a ball valve 94. When a solenoid 98 receives a signal from a timer or a manual device the solenoid 98 unseats the valve 94 and inlet pressure depresses the diaphragm 72 so closing the ports 86 and urging the closure 54 on to a lower seat 56 whereby the inlet 44 is open to the outlet 46 and the exhaust port 42 is closed so inflating the boots. The closure members 54 has inlaid rubber grommets 60 aligned with the seats 54, 56.
