Title: Single lever engine control unit particularly for the engine of a marine craft
Inventor: MORSE JOHN FRANKLIN
IPC: B60W30/18
Filed: 1969-07-17
Abstract: 1,235,579. Marine craft control units. NORTH AMERICAN ROCKWELL CORP. 17 July, 1969 [27 Aug., 1968], No. 35986/69. Heading B7V. [Also in Division F2] A single lever control unit 10d actuates the throttle of the engine of a marine craft by a push-pull throttle control cable 85 having a core 88 and casing 92 the core being operatively connected to the engine throttle and the control unit also actuates transmission 56. The control unit comprises a chassis 11, a control lever 18 movable through shift and throttle ranges from a neutral position, a throttle actuation member 29 mounted on the chassis for selective rotation in response to movement of the control lever, a throttle connecting trunnion 86 for attaching the core of the push-pull control cable to the throttle actuation member to effect shifting of the transmission 56 only during movement of the control lever through the shift range. A positioner block 93 is mounted on the chassis and anchor clip 105 secures the throttle control cable casing 92 to the block. Gear-teeth 48, 49 operated by movement of control lever 18 engage tooth 50 through the shift range only to move block 93 and thereby displace the securing clip 105 along a path generally parallel to the path along which connecting trunnion 86 is displaced thereby providing throttle dwell.

Abstract: 1,005,923. Two-part couplings. A. JUST, and M. R. JUST, [trading as MALCO MANUFACTURING CO.]. Oct. 6, 1961 [Feb. 13, 1961], No. 36006/61. Heading H2E. Male or female pin terminal connectors (Fig. 1), whose sleeves have head portions 8, 11 of polygonal section, are mounted in some or all of the apertures 26 of a baseboard 24 (Fig. 5) being so arranged that the rotational movement, due, e.g. to the wrapping of wire leads around the shank 28, of any connector, is limited by its head portion abutting against the heads of adjacent connectors. A female connector has a terminal pin 20, having a wire wrap shank 28 and a gripping shank 32 with tines 34 forming the socket, the pin being forced to fit into a sleeve 22, which is of a material softer than the pin 20, e.g. nylon or copper. The sleeve 22 is inserted into an aperture 26, and the pin 20 put in position (Fig. 3, left). The pin is then driven into the sleeve, portion 2 of which is caused to expand thus securing the sleeve to the board 24. The intermediate portion 10 is provided to prevent the head portion 8 from expanding and touching adjacent sleeves. Portions 2, 10 may be of polygonal cross-section. The male pin is similarly forced into an interference fit within its sleeve, from which the male prong 5 protrudes. The assembly process may be carried out automatically. To enable easy engagement of a pair of baseboards, carrying respective patterns of male and female connectors, the head portions are bevelled to provide spaces for aligning pins 76 on one board and apertures on the mating board. Some sleeves in the board may be conducting and others of insulating material. Specification 967,325 is referred to.

Abstract: 1428379 Dyeing polyester-cellulosic unions IMPERIAL CHEMICAL INDUSTRIES Ltd 12 July 1973 [2 Aug 1972] 36018/72 Heading D1B Unions of aromatic polyester and cellulosic textile materials are dyed in a batchwise process by immersing the union in an aqueous liquor containing an alkaline metal salt of a disperse dyestuff which contains at least one carboxylic acid, sulphamoylaryl or tautomeric keto-enol group but which is free from sulphonic acid groups, adding an acid to lower the pH of the liquor to below 7, and in an aqueous liquor containing a water-soluble reactive dyestuff for the cellulosic material and an alkali. The disperse dye may be applied before or after the reactive dye in separate dyebaths or both dyes may be applied from a single bath. When the disperse dye is applied after the reactive dye, or is fixed after the reactive dye in the single bath process, then an alkali after treatment is necessary to remove unfined dye. The disperse dye is soluble under alkaline conditions and precipitates on addition of acid; addition of an anionic or non-ionic dispersing agent before acidification maintains the disperse dye in a finely dispersed form.

IPC: G03C8/40
Filed: 1963-09-13
Abstract: Cobalt leucophthalocyanine is prepared by refluxing urea, cobalt chloride and ammonium nitrate in nitrobenzene to give a cobalt phthalocyanine intermediate product.  This product is nitrated with concentrated nitric acid and then reacted with stearyl-amine to give cobalt leucophthalocyanine, an orange product.  Alternatively the nitrated product is refluxed with N - methyl - N - (2 - hydroxyethyl) - propylene-1,3-diamine to give an orange-yellow cobalt leucophthalocyanine.  Cobalt leucophthalocyanine was purified by dissolving it in concentrated sulphuric acid and removing the cobalt phthalocyanine thus precipitated.  Specifications 679,677, 679,678, 703,669 and U.S.A.

Title: Epoxy resins
IPC: C08L63/00
Filed: 1965-08-25
Abstract: Curable epoxy resins containing at least 15 wt. per cent of halogen and having an epoxy equivalency greater than 1 are the reaction products of (1) an acid catalysed phenol-aldehyde condensate, (2) a halogen free polyglycidyl of a polyhydric phenol, and (3) a halogenated polyhydric phenol.  The novolac resin (2) may also contain halogen.  Components (1), (2) and (3) may be reacted in the presence of LiOH, NaOH or KOH at 50-200 DEG  C., the reaction being stopped whilst the resultant resin is still curable.  The curable halogenated resins may be thermoset by further heating at 50-200 DEG C. or may be cured by conventional catalysts and reactive hardeners for the curing of epoxy resins. The curable halogenated resins are useful as laminating resins and adhesive binders, in tooling and abrasive wheel applications, and in electric relays, gears and bearings.

Title: Improvements in or relating to methods of manufacturing crystalline material
IPC: C30B13/26
Filed: 1956-11-30
Abstract: <PICT:0838848/III/1> In a method of manufacturing crystalline semi-conductor material in which a fractional portion of a molten mass of semi-conductor material containing impurities is cooled to initiate crystallization, and additional increments of the molten mass are progressively cooled at the interface between the crystallized portion and the molten mass to crystallize the material by continued accretion to the crystallized portion, the molten mass in the region adjacent to the interface is progressively increasingly agitated to maintain the impurity content of the crystallized material constant throughout its length. Semi-conductor material 13 (Fig. 1), such as germanium or silicon, containing a donor or acceptor impurity, is placed in a crucible 10, and is melted by an inductive heating coil 11.  A seed crystal 14 is brought into contact with the melt and is slowly withdrawn in direction Y to grow a continuous crystal, the crystal holder 15 being rotated by gears 18 and 19 and a motor 17. The melt adjacent the interface 16 is progressively increasingly agitated as the crystal is grown, either by increasing the angular velocity of the seed crystal 14, or by vibrating the crystal by means of a transducer 20 mechanically connected to holder 15 and electrically coupled to a signal generator 21, the frequency of the driving signal from generator 21 or the amplitude of vibration being progressively increased.  In another method semi-conductor material containing a small amount of impurity is placed in a boat 30 (Fig. 3) and melted by an induction heating coil 31.  The boat 30 is slowly withdrawn in the direction M to permit the melt to cool and crystallize.  A transducer 33 connected to a source of ultrasonic-frequency electrical energy 35 is placed in contact with the crystallized portion 34, and agitation of the melt in the region of the interface 36 is increased as the crystal is grown.
