Title: Hydroxyalkylsulfonylmethyl groups containing monoazo dyestuffs
IPC: C09B62/51
Filed: 1960-12-30
Abstract: The invention comprises dyes of formula <FORM:0921550/IV(a)/1> where Y and Z are H or alkyl or alkoxy groups of 1 or 2 carbon atoms, n is 2 and B is a coupling component residue which, if the dye is otherwise insoluble, has a sufficient number of sulphonamide, carboxylic or sulphonic acid groups to solubilize the dye.  The dyes are made by conventional diazotization and coupling processes and solubilizing groups may be added at a subsequent stage.  The preferred diazo component is 5-amino-2-methyl-m-xylylene-a 1, a 3-bis(2-sulphonylethanol).  Representative of indicated coupling components are anilines, phenols, naphthylamines, naphthols, pyrrols, indoles, 2-hydroxycarbazoles, 3-hydroxydibenzofurans, 2-naphthol-3-carboxylic acid arylamides, amino and hydroxy pyridines, pyridines, pyrimidines, 2,4-dihydroxyquinoline, 9-methylacridine, 5-pyrazolone and acetoacetic acid anilide.  The dyes are preferably used on cellulosic materials but also colour natural and synthetic polyamides such as wool, silk, casein, zein, nylon, polyurethanes and polyesters.  In examples, which illustrate the preparation of the dyes and their use in colouring cotton in a variety of shades, diazo components used, other than the one preferred, are 5-amino- or 5-amino-4-methyl-, or 4-ethoxy-, or -2-methoxy-m-xylylene-a 1,a 3-bis(2-sulphonylethanols) representative of coupling components used being p-(3-methyl-5-oxo-pyrazolin-1-yl)-benzenesulphonic acid, N-acetyl-H-acid, 2-naphthylamine-6-sulphonic acid, 1-amino-7-naphthol, 2,3-dihydroxynaphthalene, 1-naphthylamine and naphthionic acid.

Abstract: 1,197,324. Colour television tubes. SYLVANIA ELECTRIC PRODUCTS Inc. 3 Oct., 1967 [3 Oct., 1966], No. 44922/67. Heading H1D. A method of manufacturing a screen for a colour television tube comprises applying to or forming on a support a mixture of phosphor particles and a radiation-polymerizable binder in an atmosphere substantially inert to the ingredients of the mixture, and subsequently exposing the mixture to actinic radiation. The atmosphere is preferably argon, krypton or xenon, but may include oxygen in combined form, e.g. as carbon dioxide; uncombined oxygen must be avoided as it combines with the phosphor and the binder with deleterious effects. If the binder is sprayed on to the support, the spray gas should also be inert.

Title: Absorption refrigeration systems
IPC: F25B15/06
Filed: 1965-11-01
Abstract: 1,109,324. Refrigerating. CARRIER CORPORATION. 1 Nov., 1965 [14 April, 1965], No. 46166/65. Heading F4H. In an absorption system comprising a generator 12, separator 11, condenser 3, evaporator 4 and absorber 5, a pump 44 passes strong solution from the absorber to the generator through a line 46 opening into an equalizer line 12 between the separator and the generator and a line 48 connects the absorber sump 36 to the equalizer line 12 at a point above the opening of line 46. With this arrangement, during start up, the pump 44 recirculates weak solution through the line 48 to the absorber until solution in the generator begins to boil and supply the separator 11 via vapour lift tube 10 when weak solution from line 46 passes direct to the generator. If supply of strong solution from the separator 11 to the absorber through line 25 becomes retarded, solution will build up in equalizer line 12 and pass through line 48 to the absorber. When operation of the pump 44 is discontinued the relaxation of the pressure difference between the absorber 5 and the equalizer line 12 will allow solution to pass from the absorber to the generator through line 48 to ensure the presence of sufficient liquid in the generator for start-up. The system uses water as refrigerant and lithium bromide solution as absorbent.

Abstract: 1,120,866. Valves. ABEX CORP. 2 Nov., 1965 [18 Jan., 1965], No. 46396/65. Heading F2V. [Also in Division G3] A valve 46 controlling the outlet line 45, 38 of a variable displacement pump 21 is closed by energizing a solenoid 94 to move a control valve 81 to the right to allow fluid from the outlet to flow to a chamber 98 via lines 86, 97 and restriction 102. Pressure in the chamber 98 acts on piston 51 to move valve 46 towards its seat. As the valve approaches its seat, a part 47 enters a bore adjacent the seat to restrict flow to line 86 to prevent shocks. To open the valve, the solenoid is de-energized and the chamber is exhausted via line 97, bore 92 in valve 81 and lines 87, 61, 64, the restriction 102 serving to limit the rate of opening. A pilot valve 74 slidable in valve 46 serves to maintain the outlet pressure constant (see Divisions G2-G3), the pilot valve having control surfaces 76, 77 cooperating with a bore 62 in valve 46.

Abstract: 1308217 Welding by pressure WESTERN ELECTRIC CO Inc 30 Sept 1970 [2 Oct 1969] 46489/70 Heading B3R Solid-state bonding apparatus, particularly intended for bonding the leads of beam-lead integrated circuit chips 32 to substrates 40, comprises a bonding tip, means for aligning the workpieces on a bonding axis 30 and means for causing a flexible or compliant bonding member 36 to engage the tip so as to be interposed between the tip and the workpieces during the bonding operation. In the apparatus shown eight bonding tips 48 are provided around the periphery of a rotatable and vertically movable bonding ram 46 adapted to be heated by contact with a spring-loaded heating collar 80, the compliant bonding member consisting of a suitably apertured aluminium strip 36 trained around the ram 46 between supply and take-up reels 50, 44. Sprocket projections 60 on the ram 46 engage feed apertures in the strip 36, and indexing movement of the ram 46 together with feed of the strip 36 for each successive bonding operation is effected by a drive motor 42 connected to the take-up reel and operating in conjunction with a pneumatically operated indexing device 72, 74, 76 mounted coaxially with the ram 46. The strip 36 is provided with an aperture adjacent each tip 48 for reception of a chip 32 and vacuum passages are provided in each tip to facilitate pick-up and carrying of the chips. A manually controlled positioner 26 and optical means 34 which may be swung into and out of position provide for aligning the tip 48 with a chip 32 in a chip tray 28 as well as for aligning the chip 32 when carried by the tip 48 and strip 36 with the substrate 40. Pressure for the bonding operation is applied to a hub 108 of the ram 46 by means of an air pressure controlled diaphragm assembly 104 operating through a lever arm 106. The strip 36 is notched at its edges to provide tab portions which are folded over the edges of the bonding tips 48 by an engagement assembly 62, which also functions to press the strip on to the sprocket projections for proper engagement therewith. It is envisaged that the compliant strip may have apertures to accommodate a plurality of chips which are then bonded simultaneously to the substrate; furthermore the chips may be premounted in the strip as mounted on the supply reel.

Title: Laser device particularly useful as a surgical instrument

Filed: 1973-10-08
Abstract: 1417907 Welding by fusion U SHARON 8 Oct 1973 [11 Oct 1972] 46830/73 Heading B3R [Also in Division A5] A laser beam manipulator comprises a tubular enclosure 7 containing an opening 8 which defines a working area, in which an object to be treated may be placed. The beam from the laser is directed into the tube and is brought to a focus 9 near the opening 8, but is intercepted near the opening and is prevented from emerging from the enclosure; in the embodiment illustrated this is accomplished by concave mirrors 14, which also focus the beam. The mirrors 14 are so designed that the rays returned by them are not perfectly parallel, in order not to reflect the beam back into the cavity of the laser 2. An eyepiece 20, and an illumination system 22, 24, are provided for visual observation of the working area. Various arrangements are proposed to ensure that no part of the beam travelling inside the enclosure misses the obstruction 14, and escapes through the opening 8. In the embodiment illustrated the beam entering the tube 7 is divided by mirrors 10 and 12 into two beams close to the wall of the tube. In other embodiments, Figs. 3-5 (not shown), the beam has an annular cross-section produced either by a conical lens or by a deflector, which intercepts the central area of the beam, or by an annular window, or by coaxial electrodes. In other arrangements the beam is focused before entering the tube; in a proposal illustrated in Fig. 6 (not shown) the beam is directed off-axis towards an obstructing mirror at one side of the tube; in the variation of Fig. 7 (not shown) the beam travels axially, but the opening is off-axis, so that the end wall of the tube constitutes a beam trap.
