Title: Improvements in or relating to electrical overload protection arrangements
IPC: H01F27/40
Filed: 1965-08-31
Abstract: 1,103,700. Protective systems. SIEMENS A.G. 31 Aug., 1965 [31 Aug., 1964], No. 37156/65. Heading H2K. An overload protective arrangement comprises a potential divider formed by one or more positive temperature coefficient resistors KA responsive to the temperature of a protected conductor or conductors, e.g. a transformer winding and a fixed resistor R5, a Zener diode Gr3 connected across the divider, a transistor Ts 1  having its base connected to the divider, a Zener diode Gr4 in the baseemitter circuit of the transistor and a relay MAI in the collector circuit of the transistor. Normally the transistor Ts 1  is conducting, the relay MAI is energized and at contacts mAI 1  maintains energized a relay A having its contacts in the supply circuits to the protected apparatus. When a resistor KA is heated to a predetermined temperature, the transistor Ts 1  ceases to conduct and relay MAI releases, opening its contacts mAI 1  to cause the relay A to release and interrupt the supply to the protected apparatus. The relay MAI also closes its contacts mAI 2  to energize a " blocking " relay MAII which at contacts mAII 1  short-circuits the potential divider KA, R5 to prevent the transistor Ts 1  from conducting when the resistor cools, and at contacts mAII 2  completes a holding circuit for itself. The arrangement shown is for the protection of the supply circuits of a radio relay station, the relay A being common to both the transmitter and receiver supply circuits, but the other components are duplicated.

Title: Improvements in or relating to the manufacture of reinforced unsaturated polyster resin sheets
IPC: C08L67/06
Filed: 1959-11-05
Abstract: Storable reinforced unsaturated polyester resin sheets which are capable of being shaped mechanically are prepared by (a) treating a permeable layer of reinforcing material with a polymerization initiator comprising a salt of a polyvalent metal or of boron, (b) impregnating the treated layer with an unsaturated polyester resin composition containing a polymerization catalyst and partially polymerizing the composition to the gel stage and (c) subjecting one or both faces of the impregnated layer to the action of heat and/or a polymerization accelerator to form a thin, more fully polymerized surface layer. The accelerator may be used in admixture with a mono- or di-isocyanate.  The initiator may be a halide, sulphate or naphthenate of tin, iron, zinc, aluminium, cobalt or manganese; it may be dissolved in ethylene glycol and diluted with ethanol or a suitable monomer, e.g. vinyl acetate.  The polymerization catalyst may be benzoyl peroxide and the unsaturated polyester resin composition may also contain an inhibitor, e.g. 4-methyl-2,6-di-t-butylphenol and a filler, e.g. calcium carbonate. The resin used in the example is a polyester of ethylene glycol and maleic and phthalic anhydrides and adipic acid mixed with methyl styrene.  Styrene may also be used as comonomer.  The reinforcement may be a natural or man-made fibre or fabric, e.g. glass fibre or paper.  The accelerator may be a mono- or di-alkyl aniline or an alkylaryl or diaryl guanidine; it may be applied in admixture with a modifying agent for the resin, e.g. toluene diisocyanate, and a lubricating agent, e.g. mixtures of mono- and di-alkyl phosphates and/or waxes, e.g. stearamide or polyethylene wax or hydrogenated castor oil.

[Also in Division B5] A plastics working extruder and plasticizer comprises a feed screw 30, temperature controllable perforated plates 5-7 and stirring and kneading elements 31, 32 mounted on a shaft 34 which passes through screw 30, the shaft being rotated and oscillated axially by drive means 55. Plates 5-7 may be provided with induction or resistance heaters or fluid flow passages (9, 10), Fig. 2 (not shown). Generally the plates are heated, but if the mechanical working of the material due to movement of elements 31, 32 and passage through the plate perforations is excessive, they may be cooled. Screw 30 does not move axially and a helical groove 36 prevents movement of plasticized material between screw 30 and shaft 34. In a second embodiment, Fig. 1 (not shown), feed is by means of a ram (20) and in this case a shaft carrying stirring and kneading elements (22, 23) is fixed to ram (20) and the whole assembly rotates and has a relatively slow axial reciprocating movement on which is superimposed an impulsive axial oscillation. In a third embodiment, Fig. 5 (not shown), a feed piston (41) reciprocates axially and is keyed to rotate with a shaft (43) carrying the stirring and kneading elements, but moves axially independently thereof. A seal (45) prevents leakage of plasticized material between piston (41) and shaft (43).
