Title: Improvements in electrically heated vessels
IPC: A47J27/00
Filed: 1948-09-17
Abstract: 654,128. Heating vessels by electric resistances. DUNLOP RUBBER CO., Ltd., POWELL, E. F. Sept. 17, 1948, No. 24395. [Class 39(iii)] Vessels for heating liquids, e.g. kettles or saucepans are heated by an electrically conductive resinous coating on their inner or outer surfaces. The coating is a dispersion of graphite or carbon black in a synthetic resin e.g. a silicone resin. Each end of a conductive band on the outside of a glass flask may be sprayed with metal e.g. zinc or may be silver-plated to form terminals on which springy brass strips are pressed. A protective coating of insulating resin is then applied over the heating surface, which has a resistance of 5-50,000 ohms per sq. cm. If the vessel surface is metallic, an insulating resinous coating is first applied, and the vessel may form an earthed terminal for the heater. An aqueous solution of colloidal graphite may be incorporated in a resin solution, which is applied as a coating and when heated forms a water-insoluble resin. Immersion heaters are formed by filling long tubes with the conductive solution, emptying the tubes and leaving a coating the tubes being finally sealed. Among the resins used are polyvinyl, phenol, glyptol, copal and coumarine resins; ethyl cellulose and cellulose acetate may be used.

Abstract: 298,467. Siemens -Schuckertwerke Akt.-Ges. Oct. 8, 1927, [Convention date]. Alternating-current induction machines; motors, controlling; dynamos, regulating.-A winding for alternating-current machines is adapted to have its connections varied without change of pole number so that it can work on networks of two different frequencies and the change takes place in such a manner that the width of a phase band in one connection is double that in the other. Fig. 1 shows one connection for a four-pole three-phase single-layer winding and above the winding the horizontal line shows 12 adjacent phase bands. For the second connection, Fig. 2, the phase bands are doubled in width by altering the phase of some of the conductors or coil sides and overlap each other. In each case, the supply terminals are u1, v1, w1, the connections being altered at the terminals x1 - - z1, x2 - - z2 and u2 - - w2. In the case of a double-layer winding, each two adjacent groups of conductors or coil sides in each layer which in one connection belong to two different phases are allotted to one phase in the other connection. The invention is applicable to synchronous, asynchronous, and alternating- current commutator machines.

Patent GB-1044471-A (GB)
Title: Improvements in or relating to acrylonitrile polymer fibers
IPC: D01F8/08
Filed: 1963-06-24
Abstract: Permanently crimped composite acrylonitrile polymer fibres are made by simultaneously spinning at least two different spinning dopes in eccentric relation, the acrylonitrile polymers in the respective dopes, when spun into fibres, having heat-shrinkages differing by at least 1%, subjecting the spun composite fibres to a primary stretching of 4-10 times, and heat-treating the stretched fibres for shrinkage in steam at 110-150 DEG C thereby to develop crimps.  The fibres may be in relaxed state when heat-treated.  In a further embodiment both the heat-shrinkages and the sums of heat-shrinkage and strain recovery of the polymers in fibre form differ by at least 1%, the primary stretched fibres are heat-treated at 80-250 DEG C and then subjected to a secondary stretching of less than 3.0 times, followed by relaxation.  The primary heat-treatment may be carried out for shrinkage, or the fibres may be under tension in order to fix the fibre shrinkage.  The secondary stretching may be carried out in a heating medium e.g. air, steam or water, at a temperature below 250 DEG C using a stretch ratio just sufficient to straighten any crimps developed by the primary stretching.  The relaxation following the secondary stretching may be effected by a secondary heat-treatment in e.g. water or steam at 80-250 DEG C, thereby developing crimps. Alternatively, crimps may be developed after the fibres have been formed into yarn or fabric.  In this case, the fibres, after the primary or secondary stretching, are mechanically crimped, spun into yarn or fabric, and heat-treated in e.g. boiling water, to develop crimps.  In an Example, composite fibres made by co-spinning two different acrylonitrile/vinylacetate copolymers are stretched in boiling water, heat relaxed in steam at 140 DEG C, heated under tension in steam to remove crimps, then mechanically crimped and cut into staple fibre, which is spun into yarn and treated in boiling water for 30 minutes.
