Filed: 1948-03-30
Abstract: 649,149. Joint-making packing. CAILLAS, J. March 30, 1948, No. 9012. Convention date, March 18. [Class 122(iii)] (Also in Groups VIII and XXII] Laminated plastic metallic strips for making heat-engine gaskets and the like are made by cooling a strip of metal foil while applying natural or synthetic resin base adhesive between successive turns, cutting the coil so formed and unrolling it flat. The foil is fed from a reel 6 on to an anti-clockwise rotating cylinder 3 over a reversely flexing roller 15 and under an adjustable spring-loaded roller 31. A rubber-lined spreader roll 19 for the adhesive is mounted on a pivoted bath 16 and maintained in contact with the coil by a spring 25. After the requisite number of turns an automatic revolution-counter (not shown) rotates a cam 23 which tilts the bath and moves the roll 19 away from the work. The cylinder 3 continues to rotate until the portion to which the adhesive has been applied is covered and the coil so formed is then removed by cutting along a slot 30 in the cylinder 3. The adhesive is preferably phenol - phthalein resin commercially known as " Glycophene N.V.S." dissolved in an equal amount by weight of trichloroethylene.

Patent GB-579983-A (GB)
Title: Improvements in and relating to the bonding of rubber to brass-plated surfaces
IPC: C08J5/12
Filed: 1943-06-10
Abstract: In the process of bonding rubber to metal, the surface to be bonded is brass-plated, solutions of sulphur and a long-chain fatty acid are applied to a part of a freshly-plated surface which formed part of the same cathode as that to be bonded, the surface being heated before or after application of the solutions sufficiently to cause the appearance of a colouration indicating that a satisfactory bond can be produced, and rubber is then bonded to the surface by the usual method.  Preferably, the solutions are applied to a part of the surface of each individual component to be bonded, but not to the actual part to which the rubber is to be applied.  The sulphur may be dissolved in, carbon bisulphide, and the fatty acid, e.g. stearic, oleic, palmitic or mixtures thereof, may be dissolved in benzene; preferably the solvents are miscible so that the solutions may be applied simultaneously.  One part of a 1 per cent solution of sulphur and 4 parts of a 1 per cent solution of stearic acid may be used. The surface is heated, e.g. during the final washing and drying steps of the plating-process, preferably to a temperature of about 140 DEG C. for a period of 20 minutes, whereby a colouration varying from dark yellow to green-brown will be produced if the surface is suitable for bonding.

Filed: 1929-03-25
Abstract: 308,650. Samans, W. March 23, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Generating by reduction of pressure.-Water circulated at high velocity and pressure through a heated coil 19 by a pump 21 is passed through a nozzle 22 into a chamber 23, from which the steam generated by the reduction of pressure of the heated water, and the unevaporated water are led off through pipes 34, 36 into a receiver 26. The nozzle discharges the hot water against the blades of a turbine 33 serving to drive the circulation pump 21, the pump 58 supplying fresh feed through a heated coil 14 to the reservoir 26, and the pump 17, supplying air to the burner and combustion chamber. The steam may be led through another turbine on its way to the reservoir. A part of a hot water from the coil 19 is led under the control of a valve 62 through a coil 20 placed in the path of the furnace gases and connected to the steam and water reservoir. The valve is operated automatically in accordance with the temperature of the escaping furnace gases. The steam is led off from the reservoir through a superheater 28. The fuel and air supplies are regulated automatically in accordance with the pressure and flow of steam in the steam delivery pipe. The discharge of water through the nozzle 22 is automatically controlled by means responsive to the temperature of the water, the control being effected by varying the degree of opening of hinged plates at the outlet of the nozzle and by moving a needle valve at the inlet.

In a sequentially fired kiln of the Hoffman type using intermittent injection burners, an igniter is arranged in the central heating well of the front line of burners so as to produce a temperature in the vicinity of the heating well sufficient to ignite a fuel/air mixture injected by a burner. An electrically heated coil 8 is carried by a sleeve 9 passing through a cover 3a which carries the nozzle 5 of an intermittent injection burner 4. The sleeve 9 slides in a collar 10 supported by a tripod 19, 20 so that the position of the collar 8 may be adjusted by screws 11. The position of the nozzle 5 is adjusted by a screw 23 so that the jet of fuel passes axially through the coil 8. Additional air for combustion may be fed through the sleeve 9, and outlet dampers controlled by rods passing between the stacks of work to be fired enables the flame front to be controlled. The cover 3a with its burner and igniter is moved to the central heating well of each row of wells as it becomes the front row so that ignition of the central burner is not delayed.

IPC: B60T17/10
Filed: 1919-04-16
Abstract: 144,432. Cross, J. W., and British Air Brake Co. April 16, 1919. Fluid-pressure.-In compressed-air or vacuum braking-apparatus, the packing of the brake-cylinder piston in the normal " brakes-off " position acts as a valve permitting communication in one direction only through a by-pass in, or attached to, the cylinder wall and connecting opposite sides of the piston. The Figure shows a compressedair brake-cylinder with the " brakes-off " position of the piston in dotted lines. Train-pipe air enters at 12 and feeds through port 9, bye-pass 8, and port 10 past the cup-leather 7, which prevents leakage in the reverse direction to the auxiliary reservoir 11. Movement of the piston to the position shown in full lines, when pressure on the train-pipe side is reduced to apply the brakes, cuts off the by-pass altogether.
