Title: Improvements in or relating to the coating of metal with a second metal
Inventor: TOYE TREVOR CYRIL
IPC: C23C2/02
Filed: 1954-10-14
Abstract: 817,209. Coating metals with metals. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Oct. 14, 1955 [Oct. 14, 1954], No. 29625/54. Class 82(2) Continuous or elongated metal bodies ("strip") (e.g., steel) are coated by applying liquid metal (e.g. aluminium, zinc or tin) by applying means so arranged that there is relative movement between a liquid metal applying surface and a liquid metal receiving surface. This relative movement permits of thickness control of the coating. Fig. 1 shows a steel strip 12 passing via a conventional degreaser 14 to a duct 18, then over applying rolls 22, 24 revolving partially immersed in tin baths 26 and into a cooling bath 28 past nozzles 29, 30 delivering cooling medium (water, an emulsion of cotton seed oil in water, or steam). Rubber rollers 31, 32 remove the cooling medium and the strip is dried in ducting 33 in a stream of warm air. A non-oxidizing gas including nitrogen is drawn in at 37 and expelled at 38. In another embodiment (not shown) the two coating rolls are arranged opposite one another with the strip passing vertically between them. The two rolls may each be fed with metal from a further roll which dips in the tin bath and in this case the relative motion may take place between the coating rolls and the further supply roll. In a further embodiment (Fig. 4) a narrow nozzle 52 is used to form a thin layer 55 of the molten metal which coats the strip 12. If a material wettable by the coating metal is used the delivery of the metal is effected by capillary action, otherwise a pressure feed must be used. Mechanical vibration e.g. in the ultra sonic range, may be applied at the point of tinning.

Additional studs 4<SP>1</SP> near the rotor inlet have their projecting parts 5 fitted into blind holes in the cover-plate. The invention may be applied to axial flow turbines.
Patent GB-1111970-A (GB)
Title: Long chain quaternary ammonium compounds and their use in the softening of textiles
IPC: D06M13/46
Filed: 1965-07-13
Abstract: The invention comprises a mixture of compounds each having the general formula <FORM:1111970/C2/1> in which R1 and R2 are C1- 4 alkyl groups, R3 is a hydrocarbon radical of the residual acid monomer left after the thermal or thermal-catalytic polymerization of higher unsaturated fatty acids containing 8-24 carbon atoms, or a radical derived from the said hydrocarbon radical by hydrogenation, X is an anion and n is an integer equal to the valency of the said anion.  The compounds are prepared by reacting an amine of the formula (R3)2NH with an appropriate alkylating agent.  The amines (R3)2NH are obtained from the residual acid monomer by reaction with NH3 to give the nitrile which is then hydrogenated in the presence of a catalyst.  Unsaturation present initially in R3 may be reduced by hydrogenation of the acid monomer or during the conversion of the nitrile to the amine.ALSO:A method of softening textiles and of improving the rewetting characteristics thereof comprises distributing on the surface of the fibres thereof a mixture of compounds each having the general formula <FORM:1111970/D1-D2/1> in which R1 and R2 are C1-4 alkyl groups, R3 is a hydrocarbon radical of the residual acid monomer left after the thermal or thermal-catalytic polymerisation of higher unsaturated fatty acids containing 8-24 carbon atoms, or a radical derived from the said hydrocarbon radical by hydrogenation, X is an anion and N is an integer equal to the valency of the said anion.  The compounds are preferably applied in the form of a composition comprising the above mixture of compounds plus a liquid carrier.  Specified liquid carriers are water, alone or together with an organic solvent such as a C1-4 aliphatic alcohol, e.g. isopropanol.  The treatment of birdseye cotton is described in detail.

Title: Improvements in or relating to tools adapted for use in blind riveting
IPC: B21J15/04
Filed: 1948-11-17
Abstract: 656,758. Blind riveting. AIRCRAFT MATERIALS. Ltd., and GOULD, G. H. Nov. 17, 1948, No. 29862. [Class 43] A hand-operated blind riveting tool of the lazy-tongs type includes resilient means, which tend to extend the lazy-tongs and thus hold the mandrel-engaging means in the loading position, but which are rendered inoperative by a latch device which releasably holds the lazy-tongs in a collapsed condition as soon as the rivet is set. The tool, which resembles the one described in Specification 348,818, is provided with springs 81, 83 which connect the lazy-tongs links 17, 19 respectively to extensions of the adjacent links and normally maintain the link mechanism extended, so that a head 71, which is connected to the usual slidable sleeve 13 and is grooved to receive rolls 67, 69 carried by the links 17, 19, abuts a surface 89 of the casing 11. Collet jaws 75, 77 which lie within a cone part 73 connected to the sleeve 13 are urged forwards by a spring 97 acting on a member 95 to abut a rearward extension 91 of the nose-piece 15 but are sufficiently spaced apart to receive a mandrel stem. A handle 63 is secured to the transverse part 61 of a U-shaped member 49 at the end of the lazy-tongs. The lazy-tongs link 37 is pivoted at 43 between the arms 45 of the member 49 and is pivoted at 51 to the link 41; the latter carries a pin 53 the ends of which slide vertically in slots 55 in the arms 45. The handle 63 is thus prevented from swinging relative to the lazy-tongs. The lazy-tongs is restrained in the closed-up position by a catch pin 99 in the handle piece 63 catching against a lug 103 formed on the end of end link 41. If a necked mandrel is used, the broken-off part of the stem which remains in the tool is ejected when a trigger 105, integral with the pin 99, is actuated to disengage the pin from the tail piece 103 and thus allow the springs 81, 83 to return the parts to their loading positions. Specifications 490,047. 504,928 507,358, 568,013, [Group XXII], and 613,882 are referred to. Specification 587,938, also is referred to in the Provisional Specification.

Abstract: 683,047. Dishwashing machines. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 6, 1950 [Dec. 22, 1949], No. 29880/50. Class 138 (i). A dishwashing machine has a discharge tube in the washing chamber, wherein discharge. slots in the tube are formed by a helical orifice in the wall of the tube which is partly covered by a guard member to limit the length of each slot. The machine, Figs. 1 and 2, comprises a washing chamber 1 having a hinged door 11 and in which is removably placed a dish rack. The bottom of the chamber communicates through a removable cup like strainer 17 with the inlet 3 of a pump 4 driven by a motor 5 resiliently supported on an outside wall of the chamber. The outlet pipe 6 of the pump connects through a seating gland with a pipe 7. The pipe 7 is rotatable on its axis from the motor 5 by a belt 30 and pulleys, a worm 26, worm wheel 27, a pinion 28 fixed on the worm wheel shaft, and a pinion 29 fixed on or integral with the pipe 7. However the pipe may be rotated by other means e.g. a water turbine driven by the discharge water from the pump 4. The pipe 7 is provided with a continuous helical slot 18 or with closely spaced slots arranged in a helical path extending along the length of the pipe. As shown in Fig. 4 the pipe is supported along its length by a guard 20 secured to the rear and bottom walls of the chamber which guard blanks off all of but substantially onequarter of the pipe 7 as shown by the unmasked portion 21 of the pipe. The helical slot widens as it progresses the length of the pipe. The pitch of the helix need not be uniform. For example, it may have a smaller pitch adjacent a silverware container. The bottom of the chamber is also connected to an outlet pipe 2 to which is swivably connected, through a gasket 16, an elbow 15. When the elbow is in the vertical position water and detergent within the chamber assume the level of the top of the elbow. The pipe 7 need not be positioned as shown e.g. it may be disposed at the upper rear corner of the chamber or at any intermediate location. Furthermore more than one pipe may be provided. In operation, the dishes and the like are washed and later rinsed by fan like sheets of liquid discharged from the pipe 7 which sheets continually traverse the length of the row of dishes.

Filed: 1926-11-29
Abstract: 264,136. Druseidt, P. Jan. 6, 1926, [Convention date]. No Patent granted (Sealing fee not paid). Pencil holders.-In a pencil holder of the type in which the lead is projected by a step-bystep movement, and in which the propelling-mechanism consists of a split tube b<1> provided with a conical clamping portion b mounted in a reciprocable sleeve member a, the clamping portion is extended away from the point and is also provided with a lower tubular extension guided in the point-section c, the movement of the tube being limited by means of a member projecting into a lateral aperture therein. The sleeve a is connected to a magazine tube reciprocable in the outer casing and provided with a projecting operating-head, the upper extension of the tube b<1> serving as a guide for leads falling from the magazine to the clamping portion b. The member c is secured in place in the pointed end of the casing by solder or by screwing, and the movement of the tube b<1> is limited by means of a screw, pin, wire, or, as shown, the inbent end d<1> of a spring d. The base of the tube is constructed opposite the conical surface b to enable it to grip the lead when under the influence of the sleeve a. To propel the lead, the operating-head is pressed inwards and moves the sleeve a forward against the action of the spring d, the tube b<1> and lead being carried along by the sleeve until stopped by the projection d<1>. Further movement of the sleeve a causes the disengagement of the surface b from the sleeve a, and the tube b<1> is returned by a spring f which is weaker than the spring d. At this point, the lead can be pushed back into the tube b if desired. Release of pressure on the operating-head results in the return of the sleeve a and the clamping of the tube b<1> on the lead. The member c, is provided with two slits to form a resilient finger c for gripping the lead. The operating-head is formed with an aperture, and a piece of rubber, paper, fabric, or the like, pierced from above or slit, is secured below the head so that leads may be introduced into the magazine tube but are prevented from falling out should the pencil holder be inverted.
