IPC: A44B19/06
Filed: 1953-12-01
Abstract: 742,045. Sliding-clasp fasteners. AERO ZIPP FASTENERS, Ltd. Nov. 9, 1954 [Dec. 1, 1953], No. 33351/53. Drawings to Specification. Class 44. A method of manufacturing a sliding-clasp fastener, which at least in part, is curved in the general plane of the fastener stringers, comprises the steps of imparting a curvature to at least one of the stringers by stretching or shrinking the same or a part thereof, and before, during or after the stretching or shrinking, applying a material to the stringers which substantially maintains the curvature imparted to the stringers. Preferably, two stringers are interlocked by interengaging their interlocking members, the interlocked stringers then being jointly stretched or shrunk. The material which may be applied by spraying or dipping may be a sizing, or starching material or alternatively the stringers may be coated or impregnated with a suitable plastic material, or in a modification, a settable plastic material, for example, polyvinyl chloride, may be woven into the stringer tapes, the threads of the plastic material being responsive to setting treatment. The stringers may be stretched by being drawn round a suitably curved surface. Shrinking may be effected by applying the stringers loosely to a suitably curved surface and wetting the stringers to shrink the same on to the surface. The stringers may be sandwiched between the curved surface and a mating auxiliary. surface, which may be heated.

Title: Device for automatically limiting the load moment in jib cranes
Inventor: MARKMANN RICHARD
IPC: B66C23/90
Filed: 1964-08-19
Abstract: 1,027,859. Safe load indicator for jib-cranes. SCHIFFSWERFT " NEPTUN " ROSTOCK VEB. Aug. 19, 1964, No. 33860/64. Heading B8B. In an overload prevention device for jib cranes a load cable 18 deforms a diaphragm 19 and this force is transmitted hydraulically through a conduit 3 to a cylinder 2. This produces upward movement of a piston 4 and a weight 5, which in its lower position holds a switch 14 closed by means of a pin 12. When the switch 14 is closed the luffing and hoisting winches may be operated. If a weight smaller than the safe load is lifted the weight 5 does not move. When the moment is increased by luffing the jib out, weights 8, which rest on the weight 5, are sequentially lifted by a cone 9 attached to the jib 11 by a cable 10. When the weight 4 is sufficiently unloaded by the cone 9 it moves up and breaks the control circuits of the winches. An air cushion 21 in an equalizing reservoir 20 compensates for temperature produced variations in the volume of hydraulic fluid. A solenoid valve 23 closes as soon as the crane begins to operate so that changes in pressure due to the load are not equalized.
