Title: Coating compositions-particulate polyamides
Inventor: JR HARRY A TOULMIN
IPC: C04B24/28
Filed: 1955-10-06
Abstract: Metal surfaces are coated with a composition comprising an aqueous solution of an alkali metal silicate having dispersed therein particles of a polyamide of molecular weight at least 5000 and of an average particle size such that at least 90 per cent of the particles pass through a 100 to 400 mesh Tyler screen. Specified alkali metal silicates are sodium silicate, potassium silicate or lithium silicate.  Various polyamides are specified (see Group IV (a)).  In the examples, coating compositions are prepared from: (1) nylon dust, (2) perton dust, (3) a polyamide dust derived from 6-amino-caproic acid which are ground to the required particle size and dispersed in aqueous solutions of sodium silicate.  The metal surface, e.g. iron or steel, is cleaned in a pickling bath, e.g. containing phosphoric acid and sulphuric acid and rinsed or sand blasted.  The composition may be applied by brushing, dipping or spraying and may be dried by air drying and/or forced drying.ALSO:A liquid coating composition comprises an aqueous solution of an alkali metal silicate having dispersed therein particles of a polyamide of a molecular weight of at least 5000 and of an average particle size such that at least 90 per cent of the particles pass through a 100 to 400 mesh Tyler screen.  Specified alkali metal silicates are sodium silicate, potassium silicate or lithium silicate.  The polyamides may be prepared by the condensation of acids, e.g. carbonic, oxalic, succinic, glutaric, adipic, pimelic, sebacic, phthalic or hexadecamethylene dicarboxylic acid with diamines, e.g. ethylene diamine, trimethylene diamine, propylene diamine, pentamethylene diamine, benzidine or phenylene diamine.  Other polyamides specified are those derived by the auto-condensation of amino acids, e.g. 5-amino-caproic acid and the N-carboanhydrides of a -amino acids and those derived by the condensation of cyclic amides.  In the examples: (1) nylon dust prepared by melting nylon and solidifying with dry ice prior to grinding; (2) perlon dust; (3) a polyamide dust derived by the auto-condensation of 6-amino caproic acid are ground to the required particle size and dispersed in aqueous solutions of sodium silicate.  The compositions may be used for coating metals.

Filed: 1951-12-08
Abstract: 701.666. Tennis &c. balls. DUNLOP RUBBER CO.. Ltd. Nov. 11, 1952 [Dec. 8, 1951], No. 28809/51. Class 132(2) [Also in Group VIII] A tennis &c. ball is made by applying to an inflatable ball core a surface layer of substantial thickness of a material which is removable in fluid form during felting, then applying a layer of feltable fibres and then subjecting the fibres to a felting operation and simultaneously progressively removing the surface layer to allow the felting fibres to contract on to the core. The surface layer may be of ice which is removed by melting. Alternatively a mixture of skin glue, latex, soap and water is foamed and allowed to set in hemispherical moulds. The resulting hemispheres are coated with a thin latex film and one layer of carded wool and are then placed around a ball core. The fibres are then applied and the assembly is wetted and then felted. The surface layer of foamed material is removed by occasional immersion in water during felting. The ball is then washed, dried, dipped in naphtha, dried and moulded and vulcanized. The skin glue mixture may be replaced by a gelatiriesoap mixture.

Filed: 1925-11-17
Abstract: 266,390. Dawson, Sir A. T., and Buckham, Sir G. T. Nov. 17, 1925. Steering-In a motor vehicle of the kind having endles tracks and road wheels for alternative use (1) the. front idle pulleys C of the endless tracks B are swivelled for steering by means of the ordinary steering handwheel E used to swivel the steering road-wheels D, and (2) the front road wheels are steered bv mechanism independent of the up and down movement of the wheels relatively to the chassis frame. The steering-wheel E may be connected by means of a sliding hand-controlled. clutch G<2> either to the gear E<1> swivelling the endless-track pulleys or to a gear F<1> swivelling the road wheels D. In the construction shown the. vehicle is converted from a wheeled vehicle to an endless-track vehicle, or vice-versa, by movement of the road-wheel axles about a shaft fixed on the chassis frame A, as described in Specification 265,670, [Class 79 (ii), Motor vehicles, Driving &c.], and the steering road-wheels D are operated from the gear F<1> through an arm F<3>, link F, two-armed lever H<1> pivoted on the shaft H, link H<2>, bell-crank lever H<3> pivoted on the front axle D<1>, and link H<4>. With this arrangement the up-and-down movement of the front axle does not necessitate disengagement of the steering connections. In a modification the axle D<1> moves vertically and, to allow for this movement, the bell-crank lever 11<3> has one arm sliding vertically on a square shaft.

Title: Improvements in and relating to braking devices for vehicles
IPC: B60T8/26
Filed: 1956-09-21
Abstract: 842,445. Road vehicle brakes. FRANCIA, G. Sept. 21, 1956 [Dec. 2, 1955], No. 28971/56. Class 103 (1). An hydraulic braking system for automobiles of the type wherein, as shown diagramatically in Fig. 12, a device 9 is incorporated in the system to vary the brake pressure applied to the rear wheel brake cylinders relative to the front wheel cylinders or vice versa, is characterized in that means is also provided for varying the brake pressure in the wheel cylinders on one side of the vehicle relative to that on the other in dependence on centrifugal forces as the vehicle goes round a curve. In the embodiment shown in Figs. 13 and 15, this is done by the action of a weight 18 so pivoted that when swinging fore and aft, it causes similar movement of both pistons 13 in their cylinder 12, the space below which is connected to the master cylinder and the space above to wheel cylinder on each side of the vehicle. When the weight 18 swings to one side or the other as a result of centrifugal force, one of the pistons is moved more than the other, thus producing a differential braking force responsive to the movement of the vehicle round a curve superimposed on the variation due to acceleration or deceleration in its normal line of movement.

Title: Measuring dispenser for liquids
IPC: G01F11/26
Filed: 1955-10-14
Abstract: 795,796. Liquid dispensing apparatus. LESNICK, M. L. Oct. 14, 1955, No. 29297/55. Class 106(5) A liquid dispenser comprises a measuring chamber 20, inlet and outlet ports 30, 40 each having sealing surfaces 33, 45 adapted to be engaged by valve members 31, 46, spring means 34, 48 to bias the valve members to the closed position, and a cam 62 to operate the valve members, there being a pair of co-operating bearing surfaces 42, one on the valve and one in the chamber 20, forming a hinge whereby action of the cam 62 causes pivotal movement of each of the valve members about its hinge. The cam 62 is mounted on a shaft 60 connected by spring-biased radial arms to a manually operable member 64, one of the radial arms having a cam slot to actuate a counter 12. Operation of the member 64 when the device is not in the dispensing position is prevented by a pivoted dog 70 which normally engages a surface 71, but swings clear of the latter when the device is tilted to the dispensing position. The valve members are provided with projections 50, 51 for engagement by the cam member 62 and the projection 50 also serves to close an air vent 74 when the inlet port 30 is open. Air passes into the container 17 to which the dispenser is secured through a hollow threaded rod 95. This rod carries a pair of laterally extending arms 97, 98 pivoted to a nut 96. The shaft 95 is rotated through a ratchet member 118 so that the dispenser cannot be removed from the bottle once it is installed, without breaking the bottle. A seal 104 of a soft plastic or rubber-like material is positioned between the dispenser and the end of the bottle whilst a ring member 105 prevents lateral displacement of the dispenser relative to the bottle. To increase the capacity of the measuring chamber 20, a cup member (not shown) of U-shape may be glued or otherwise affixed to the exterior chamber and connected thereto by ports. Alternatively plugs may be inserted into the chamber to reduce its volume. Specification 795,797 is referred to.
