Title: Method of improving the properties of sintered aluminium
IPC: C22C32/00
Filed: 1961-09-05
Abstract: Occluded hydrogen is removed from aluminium powder having up to 20% by weight alumina by subjecting it prior to sintering to a hot degassing treatment at 550-600  DEG C. for 10-30 hours in an oven under a vacuum of 10-4 to 10-5 mm. Hg.  Prior to the degassing treatment, the powder may be cold compacted or formed into semi-finished products such as lamina or extruded shapes.  The powder may have a grain-size of 50-200 microns and after treatment may contain only 2-5 p.p.m. of hydrogen.

Title: A method of rendering articles of polymethylene terephthalate resistant to the growth of fungi and bacterial attack when a nutrient source is present
Inventor: GLEN WILLIAM
IPC: D06M15/643
Filed: 1955-11-08
Abstract: 796,107. Proofing against fungi and bacteria. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Oct. 31, 1956 [Nov. 8, 1955], No. 31890/55 Class 140. Articles made from highly polymeric polymethylene terephthalates, e.g. polyethylene terephthalate, are made resistant to the growth of fungi and bacterial attack under weathering conditions and washing in synthetic detergent and soap solutions by treatment with orthophenyl phenol at temperatures above 40‹ C. and below the boiling point of the treating liquid followed by treatment with a waterrepelling agent such as a silicone. By the term highly polymeric polymethylene terephthalate is meant polyesters built up from terephthalic acid, one or more glycols and, if desired, a minor amount of bifunctional compounds such as isophthalic acid. The articles treated may be in the form of films, fibres, filaments, woven fabric or articles made up from finished woven fabrics. The orthophenyl phenol may be used in weak neutral aqueous dispersion and may be assisted by the addition of surface-active agents such as oleyl sodium sulphate. Zirconium oxychloride may be added to the silicone polymer impregnant. The treated material may be used as seat covers, sheets, pillow fillings and coverings, aprons, smocks and surgical dressings.

The ram housing 1 and chamber 4 are sealed and filled with gas and oil under pressure. The charge of plastics material is supplied to the chamber 11 by a reciprocable screw 18 in a heating chamber 59. Fig. 2 shows a modified enbodiment in which the mould cavity 35 is enlarged to allow injected material to foam, by reducing the pressure in a chamber 44 of a movable cylinder 39 connected to male mould member 41. Movement of mould member 41 relative to a platen. 42 is limited by adjustable nuts 51, 52 on studs 45. Initial closing of the mould is effected by cylinders 53 which drive the studs 45. Final clamping is effected by pressure fluid introduced into the chamber 44 after locking of the platen 42. This locking is done by means of a split nut 57  operated by cylinders 56 to engage a threaded portion 55 of a shaft 43 fixed to platen 42. The injection nozzle 23 is detachably fitted on a partspherical tip 82 on the injection device. The nozzle has outlet and inlet openings 25, 26 (Fig. 3) closable by valves 27, 28 respectively.
