Abstract: 1432447 Moulding containers DANIELS STROUD Ltd 10 April 1973 17274/73 Addition to 1230282 Heading B5A The process of, and apparatus for, moulding thin-walled containers of plastics material described in the parent Specification 1,230,282 is modified by injecting the material into a space 5 through an injection plate 4 via a conduit 20, and compressing the material to the form of a diaphragm received by a groove in one or a pair of rings 1 by the upward movement of a piston 3b which may be rotated both during the injection and compression stages. The diaphragm, thus held, is conveyed by a transfer plate 2 to a station where it is shaped by a punch and mould cavity, together with air pressure and/or vacuum to container form, the finally shaped container including an integral rim as moulded by the groove in the ring or rings 1. The conduit 20 is laterally movable relative to the injection plate to close its outlet. In further embodiments the plate 4 and piston 3b are shaped to provide diaphragms of non-planar form and of non- uniform thickness.

Abstract: In circuitry for generating tripping and blocking signals for the protection of electrical components in an electrical power supply network as a result of the occurrence of faults therein, respective tripping and blocking outputs for each phase of an electrical power supply network are generated such that double or triple pole tripping is prevented unless the presence of an actual second tripping signal is detected subsequent to the detection of a first tripping signal. The respective tripping signals and blocking signals for each phase of the electrical power supply network are generated in dependence on whether the fault lies ahead or behind the electrical component to be protected, respectively, in response to measurement of the voltage and current associated with transient waves generated by faults in each electrical power supply network phase. The presence of a tripping signal resulting from the occurrence of a single phase fault, and the presence of a second tripping signal resulting from the occurrence of a fault in another phase are detected. The functional level of detecting the second tripping signal is modified or adjusted upon detection of the first tripping signal.

Abstract: In an assembly, for use in transducer type instruments such as accelerometers, having a position sensing movable member including a pick-off element, wherein the movable member is secured to a support member by a flexure or hinge and the support member in turn is cantilevered between two stator members, instrument bias errors resulting from the securing of the non-cantilevered portion of the support member between the stator members can be reduced by aligning the edges of the surfaces of the stators that contact the support member with the centroid of the pick-off element so that the axis of cantilever rotation passes through the centroid of the pick-off area. In transducers having electrical leads on the movable member, the flexure and the support member for electrically connecting the pick-off element to the support member, bias errors can be further reduced by including the area of the electrical leads in calculating the centroid.

Abstract: A process for forming cloth-covered cushion articles. A mold is provided having the shape of the desired cushion article. In one form, a cloth covering is drawn into the mold. Foamable material is poured into the mold and cured to form the cushion article. The covered, cured article is removed from the mold and heated to at least the heat-fixable fiber set temperature of the cloth, as the cured foam acts as a male mold to hold the cloth in contour during heat setting. In another form, the foam is poured directly into the mold and cured. The cloth covering then is placed over the cured cushion and set.
