Title: Improvements in or relating to the production of colour effects on textile fabrics
IPC: D06Q1/04
Filed: 1956-02-10
Abstract: Colour effects are produced on textile fabrics by exposing the fabric in high vacuum to the vapour of at least one metal (e.g. Al, Cu, Sn, Ag) and then to the vapour of at least one of the group stannic oxide, antimony trioxide and lead oxide.  An organic dye may be interposed, preferably also by vapour-deposition in vacuo, between the metal and the oxide coating; and before coating, the fabric may be embossed or given a calender-glazed effect which may optionally be rendered permanent by use of a synthetic resin.  The metal layer, which may be multiple, may be between 0.5 X 10-5 and 1.0 X 10-5 cm, in thickness, the oxide layer 5 X 10-5 cm., the dye from 2 X 10-5 to 3 X 10-5 cm., the total thickness being between 0.5 X 10-4 and 1.0 X 10-4 cm.  Textiles referred to are woven and tricot fabrics; those of cellulosic fibres e.g. cotton, viscose rayon, cuprammonium or acetate rayon; animal fibres e.g. silk, wool; and fully synthetic fibres such as poly amides (Nylon Perlon), polyesters (Dacron, "Terylene", Registered Trade Mark), and polyvinyl based (e.g. "Orlon", Registered Trade Mark).

Title: Improvements in vacuum steam heating systems
IPC: F24D19/08
Filed: 1927-02-21
Abstract: 291,134. Marks, E. C. R., (Dunham Co., Ltd., C. A.). Feb. 21, 1927. Heating buildings. - Relates to vacuum steam heating systems, and consists in supplying steam to a radiator under sub-atmospheric pressure and in varying the sub-atmospheric pressure to regulate the amount of heat radiated, while maintaining a substantially fixed difference in pressure between the inlet and outlet sides of the radiator. Steam is supplied from a boiler A to a supply main B through a reducing valve C to radiators D. Condensates and air are drawn from the radiators through thermostatic traps E to a return main F and to an accumulator G. Vacuum apparatus H withdraws the condensates, vents the air, and forces the water back to the generator A. A differential pressure regulator J controls the vacuum apparatus and comprises a movable diaphragm which operates a switch 43. The diaphragm is subject on its opposite side to pressure from the supply and return mains B and F. When the difference in pressure falls below a certain minimum, the switch 43 is closed and a motor 39 operating the pumping mechanism will be started, and liquids and air will be drawn from the tank G and from the return main F. When the correct difference of pressure is established the switch 43 is opened and the motor stopped. By varying the subatmospheric pressures in the supply mains B the temperature of the steam delivered to the radiators is varied. These pressures are controlled by the valve C which has balance weights 10, 11 adjusted to maintain the desired degree of vacuum, which is indicated by a pressure gauge 13. The vacuum apparatus H comprises a tank 25 the liquid level in which is controlled by a ball 37. When the level reaches a certain height the valve 34 is opened and water' is forced through the pipe 35 to the boiler. The level in the tank G is controlled by a ball 45 which controls the motor 39 which discharges the contents into the tank 25. The reducing valve C is adjusted to maintain the desired degree of vacuum in the supply main B, and consequently the temperature of steam delivered to the radiators D. In a modification for small installations such as household systems, the boiler is heated by an automatic gas heater, and the degree of vacuum in the system is controlled by the application of heat to the boiler. The mechanism H in this system only withdraws air and the condensate is arranged to gravitate back to the boiler. The radiators emit heat at a rate just sufficient. to replace heat lost from the building and occasional manual adjustments of the firecontrols or reducing valve are only necessary to meet changes in weather conditions.
