Title: Improvements in or relating to high-speed electric cut-outs
IPC: H01H77/06
Filed: 1959-08-13
Abstract: 915,130. Fusible cut-outs. MASCHINENFABRIK OERLIKON. Aug. 13, 1959 [Aug. 25, 1958], No. 27754/59. Class 38 (1). In a high-speed fusible cut-out, a spring-loaded insulating wedge-member 4 is arranged to impinge on the fuse element 1 when a fault occurs, the resulting reduction in the crosssection of the element causing a rapid rise in the temperature thereof and consequently quicker rupturing than would occur solely by the fault current. The wedgemember is held set by a holding magnet 7 excited by a coil 10 and is released when the current through a demagnetizing winding 8 in series with the element 1 sufficiently weakens the flux through the magnet 7. The arc resulting from the rupture of the element may be extinguished by a blow-out coil 14, horns 13 and an arc-chute 15. A permanent magnet may be used as the holding magnet and demagnetization may be effected by condenser discharge. In addition, replacement of the fuse may be carried out automatically.

[Classes 70 and 87 (ii)] [Also in Groups VIII, XI and XXIII] An inflatable or deflatable bag for use in a bag moulding process employing high frequency heating comprises a flexible wall of metallised fabric having a gas-impermeable coating of flexible material. An inflatable bag 3, Fig. 1, of silvered glass fabric having an internal coating of a flexible neoprene compound, is placed between a metal platen 4 and the work 1 which is supported on a fixed former 2, mounted on insulators 5. The platen and former are connected by copper strips to the terminals of a high frequency oscillator. A deflatable bag is built up from a metal plate 21, Fig. 3, a ring 23 of insulating material, and a circular sheet 24 of metallised glass fabric having a neoprene compound on its inner surface. The joints between the various parts are gas tight. A pipe 30 connects the bag to a vacuum pump. The inflatable bag may have the gas impermeable coating on its external surface. The bag would then be capacitively coupled to the platen. The deflatable bag may also have its impermeable coating on the external surface, in which case the fabric may be capacitively coupled to the high frequency supply with the aid of a metal coating on the surface of the impermeable coating or by making the latter of conductive material. The dielectric loss heating may be supplemented by heat produced in the metallised fabric due to conductance or by heat produced in the coating due to the dielectric losses. The glass fibre may be silvered by the process described in Specification 572,071, [Group XXXVI]. The gas-impermeable coating may be a natural or synthetic rubber or flexible heat-resistant plastic. Examples are neoprene compositions or silicone polymer rubbers. A suitable composition is as follows (parts by weight) -Neoprene 35, factice 15, paraffin wax 2, clay 42.5, carbon black 1, stearic acid 0.5, magnesium oxide 1.5, zinc oxide 1.5, antioxidant 1.
