Title: Dyed textile yarn and fabrics prepared therefrom
IPC: D02G1/18
Filed: 1965-06-24
Abstract: In the production of a dyed composite yarn, fibres of a hydrophobic synthetic polymer, e.g. acrylonitrile homopolymers and copolymers, polyolefins such as polypropylene, polyamides, polyesters such as polyethylene terephthalate, are modified to improve their dyeability as by incorporation of alkylacrylamide polymers such as poly - N - alkylacrylamides, acrylic ester polymers including polyethylacrylate and polymethylmethacrylate, polyvinylpyridines poly - (vinylpyrrolidones), polyvinyl acetals, e.g. polyvinylbutyral, epoxy resins e.g. epichlorohydrinsulphide or epichlorohydrin - bis - phenol condensates, polyalkylimines, polycarbonates, polyoxyalkenes, divalent metal salts or aliphatic carboxylic acids and metal sulphonates, and are also treated e.g. by heating, drafting and cooling without relaxing, to render them heat-shrinkable.  The resultant fibres are dyeable at low temperatures, i.e. less than 160 DEG F, and are capable of at least 20% linear shrinkage on heating to elevated temperatures e.g. 250 - 300 DEG F.  These fibres are combined, as by fibre or sliver blending, with "heat-stable" fibres, e.g. cotton, mohair, wool, viscose, acrylonitrile homopolymers and copolymers, linear cyclohexane - 1, 4 - dimethanol terephthalate polyesters, polyethylene terephthalate, modacrylics, (stabilised as necessary) and formed into yarn.  The fibres (or only the shrinkable component) are dyed (the shrinkable fibres at the low temperature) separately or when combined, by cationic or basic, disperse, or premetallized dyes (which may include assistants and levelling agents such as non-ionic surfactants and phosphate compounds) before or after yarn formation, and are dried at a temperature of 180 - 220 DEG F.  Before or after the yarn is made into knitted, woven and/or pile fabric, it is heated at the elevated temperature to cause differential shrinkage of the constituent fibres and consequent bulked effects in the yarn and/or fabric.

Title: Control device in a high voltage dc-transmission system
IPC: H02J3/36
Filed: 1955-09-22
Abstract: 789,762. Automatic control systems for D.C. power transmission; converting. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Sept. 22, 1955 [Sept. 25, 1954], No. 27051/55. Classes 38 (2) and 38 (4). In a high-voltage D.C. power transmission system in which at the transmitting station A.C. is converted to D.C. by a rectifier subject to automatic voltage control, and at the receiving station the D.C. is converted to A.C. by an inverter subject to automatic frequency control ; the action of both automatic control systems is correctively modified if the rate of change of load current exceeds a predetermined value. It is stated that as alternatives, the transmission voltage may be held constant by the inverter station, that the frequency may be controlled by varying the transmitted D.C. voltage and that the inverter may be controlled to supply a constant current instead of a constant frequency. In the embodiment disclosed, the rectifier 1 supplies the D.C. line 12 (with earth return) from an A.C. source 7 and is normally grid controlled for constant output voltage in accordance with the difference between line volts measured by a magnetic amplifier 34 and a reference voltage tapped off a potentiometer 39. The control signal is passed by a rectifier 31a to a controlling amplifier 24. At the receiving station, the inverter 14 supplies the A.C. mains 19 from the D.C. line 12 and is normally grid controlled for constant output frequency in accordance with the difference between A.C. mains frequency (measured by a D.C. tachometer generator 58 driven by a synchronous motor 59 connected to the mains 19) and a reference voltage tapped off a potentiometer 64. The control signal is passed by a rectifier 56a to a controlling amplifier 49. At the two stations, magnetic amplifiers 42 and 71 measure the D.C. load current and the D.C. outputs of these measuring devices are connected via differentiating networks 44, 45 and 73, 68 and via rectifiers 31b, 56b to the controlling amplifiers 24, 49. The rate of current change signals are opposed by reference sources 47, 66. If the load current increases at a rate above a preset value due to a fault the output voltage of rectifier 1 is decreased to reduce the fault current, and if the load current decreases at a rate above a preset value the voltage of the inverter 13 is reduced.

Abstract: 363,368. Automatic exchange systems. ASSOCIATED TELEPHONE & TELEGRAPH CO., 1033, West Van Buren Street, Chicago, U.S.A. Sept. 16, 1930, No. 27680. Convention date, Sept. 26, 1929. [Class 40 (iv).] A rectifier, e.g. of the dry metal type, is connected in parallel with a relay to make it slow to operate or release in accordance with the direction of current flow. Sparking at interrupter contacts in the circuit of the relay is also reduced. As applied to a Strowger-type switch for automatic telephone systems, the release and change-over relays 36, 37 are made slow to release, and a common alarm relay 56 in the release circuit is made slow-to-operate. In the case of relays 36, 37, the rectifiers 15, 16 are poled so that they do not pass current from battery, but when the relay circuits are opened the rectifiers effectively short-circuit the relays to make them slow-to-release. In the case of relay 56, the rectifier 17 is poled to pass current from battery, the operating time of the relay being slowed by the charging up of the rectifier.
