Title: Moulding apparatus for compacting powdered materials
IPC: B30B15/30
Filed: 1981-04-01
Abstract: Isostatic moulding apparatus comprises a fixed frame assembly comprising an upper bolster (1), a lower bolster (2) and connecting rods (3) with a clamp cylinder (5) in the lower bolster; a pressure vessel (400) with removable end members (401, 108) is mounted on a support which is pivotably mounted on one of the connecting rods so that the pressure vessel can be swung into the fixed frame assembly to overlie the piston (6) of the clamp cylinder. The pressure vessel (400) and the clamp cylinder are connected to a common source of hydraulic pressure fluid so that application of pressure simultaneously clamps the end members (401, 108) and effects moulding of a compact within the pressure vessel (400). After the pressure vessel (400) is swung out of the fixed frame, the bottom end member (108) of the pressure vessel (400) is lowered so that the compact can be removed therefrom. After the bottom end member (108) has been raised again the top end member (401) can be removed to allow a further charge of powder to be loaded into the pressure vessel (400) for a further cycle of operation. <IMAGE>

Title: Load cell
Inventor: SARGENT CYRIL EDGAR
IPC: G01G5/04
Filed: 1983-02-28
Abstract: A load cell 2 to detect when the weight of an article, for example a fire extinguisher, is less than a predetermined value. The load cell has a chamber 6 filled with hydraulic fluid.The ceiling of the chamber is a rubber diaphragm 10 supporting a flat plate 20 on which a steel ball 22 rests continually on the same point on the plate.
