Title: Improvements in the formation of phosphate coatings on wire or strip
Inventor: WILKINSON CYRIL FRANK
IPC: C23C22/14
Filed: 1953-05-22
Abstract: A method of forming a phosphate coating on a wire or strip comprises passing the wire or strip with a chemically clean surface continuously in an axial direction through an accelerated phosphate coating solution having a pointage greated than 30 and so correlating the speed of travel and the duration of immersion of the wire or strip in the solution with the degree of acceleration of the solution that initial formation of the coating takes place in the solution, that the wire or strip emerges from the solution carrying a uniform film of the solution by which the coating formation is completed and that the coating is crystalline and weighs not less than 250 mgms. per square foot.  Wire or strip made from ferrous metals, zinc, cadmium and aluminium may be coated and the chemically clean surface is obtained by patenting or close-annealing, if necessary followed by pickling, e.g. in 10 per cent HCl, and passage through a grit or other mechanical scrubbing device.  Preferably, the accelerator is a chlorate, the solutions used those disclosed in Specification 706,315, i.e. dihydrogen phosphate solutions accelerated with a chlorate or a mixture of a chlorate and a nitrate, the contents of phosphate (as P2O5), chlorate (as CIO3), and nitrate (as NO3), being such that (chlorate + nitrate)/ phosphate lies between 0.1 and 0.6, the metal of the solution is zinc, the pointage 60-80 and temperature of use 150 DEG -180 DEG F.  The coating weight may be increased by the addition to the solution of 0.1-0.2 per cent of an  -amino polycarboxylic acid or 0.02-0.08 per cent of a soluble copper salt. To assist the coating formation the wire or strip may be heated as it emerges from the solution, e.g. by a Bunsen burner flame or an induction coil; in this case, the solution pointage is preferably 50-70.  If the wire is to be drawn a lubricant, e.g. drawing soap, may be applied directly to the phosphate coating or over a coating of borax or lime.  If the wire is to be stored, corrosion thereof may be prevented by applying a protective material over the phosphate coating, this may be the lubricant in the subsequent drawing operation and is advantageously the drawing soap to which a corrosion inhibitor, e.g. sodium nitrite, chromate or benzoate, has been added. Among solution specified in the examples are those containing (a) zinc oxide, phosphonic acid and sodium nitrophenol sulphonate (b) zinc oxide, nitric acid, phosphoric acid and sodium nitrite and (c) sulzinc primary phosphate and nitroguanidine.

Title: Improvements in or relating to metal to ceramic seals
Inventor: TOWLER ERNEST EDMUND
IPC: C04B41/88
Filed: 1957-05-08
Abstract: A ceramic surface is metallized by coating with a mixture of one or more powdered oxides of manganese and one or more powdered metals selected from iron, nickel, tungsten and molybdenum, and then sintering.  Specifically, the ceramic body, e.g. a forsterite component of a transmitting valve, is coated as by brushing or spraying with a mixture of the powders in a liquid carrier, e.g. diacetone alcohol containing a binding agent such as nitrocellulose, and then sintered in a reducing atmosphere such as hydrogen at a temperature of 1300 DEG C.  To facilitate brazing to another body, the metallized ceramic may be electroplated with nickel and heat-treated in hydrogen at 1000 DEG C. to strengthen the plating.

Abstract: 802,933. Seaming non-metallic sheet material. PHOENIX RUBBER CO., Ltd. May 9, 1957 [May 11, 1956], No. 14708/56. Class 42 (1). An automatic welding plant for plastic flooring comprises a blower unit arranged to blow air through an electric heating chamber to a nozzle 25 arranged to direct a blast of warm air to a welding rod 27 which is guided along the underside of the machine by means of a tube 26 and grooved roller 21. Wheels 18 are driven by a geared electric drive motor. In operation, the heating unit and blower unit are switched on and the blast of air is directed at the welding rod. When the correct temperature has been reached a thermostat switches on the electric motor and the machine moves forward. As the temperature of the heating chamber increases, further thermostats increase the speed of the drive motor. A thermostat controls the heating chamber to prevent the temperature of the hot air rising above that required for welding. A stop switch which may be associated with a neon warning light is provided at the front of the machine for contact with a wall or a previously prepared stop block. The grooved wheel may be replaced by one having a different size of groove for welding material of different thickness. The blower unit may be used to provide an air blast for cooling the weld. A guillotine blade may be fitted to operate at the end of the tube 26. The welding rod may be wound on a drum mounted on the machine and driven at a speed co-related to the forward speed of the machine.
