Title: Moulding ceramic objects using electrically - charged moulds
IPC: C25D1/14
Filed: 1969-03-18
Abstract: Ceramic objects may be moulded effectively and economically by casting into a mould formed of Al, Cu or graphite or made of some non-conductive material such as wax or synthetic resin coated with a conducting material. The ceramic slip may be constituted of 50-91% by weight of particles of 0.015-4.76mm diameter of SiO2, Al2O3, Cr2O3 and other non-metallic compounds of such sort dispersed in 50-9% weakly conducting polarised organic liquids and water. A potential of 10-800 volts is applied across the slip using the metal conducting mould as negative electrode and a conical Al rod, coated with a release agent and inserted in the centre of the mould cavity, as positive electrode. The passage of current through the slip causes the ceramic compound to flow to the mould walls concentrating the liquid agent near the positive electrode. If the mould has a simple contour consisting of straight lines and curves, it may be withdrawn readily from the mould. The moulded object has a shrinkage of about 0.5%.

Title: Filter mat - for covering the bank of a water channel is formed from synthetic water resistant yarn
IPC: E02B3/12
Filed: 1972-12-20
Abstract: A filtering mat for covering the bank of a water channel is woven from synthetic yarn (e.g. nylon, polyethylene, polypropylene) and has a mesh size sufficient to allow the passage of water but prevent the passage of large particles. The near face of the mat has pockets which are produced by forming a double walled fabric and interweaving the two walls together in the regions around the pockets. The wall of fabric defining the pockets is of lesser width than the wall defining the mat whereby particles passing through the mat are collected in the pockets. Pref. the open mouths of the pockets are connected to the mat by a small number of warp yarns. The mat can be produced more cheaply than by methods in which the pockets are stitched.

Title: Self-supporting anti-twist electric cable - uses multi-layer steel supporting wires and a conducting overlay
IPC: H01B11/18
Filed: 1973-09-17
Abstract: The cable is designed to be self supporting as a result of steel wires, normally several in parallel, arranged so that the cable does not twist. This design and method of manufacture minimises the tendency of the load bearing steel wires to move away from each other during the fabrication process of the whole cable. The cable may be stored and taken from such a store without any twisting problems. The central steel conductor (1) has three further layers of such cables (2, 3, 4) wound such that the successive layers are of opposite sense to each other. Layer (5) is a metallic packing layer. Around all the cables is the conducting layer of copper (6). Also described is the fabrication machinery.

A horizontal force is then exerted on the sack on the centre of the side furthest from the bellows, together with two parallel forces opposed to the first. One of these acts near the lower sack edge and the other on teh upper one, the effect being to bend the sack and lift the upper bellows section clear of the sack body.

Title: Turbogenerator damping winding - minimises unstable conditions causing overheating during fault
IPC: H02K3/16
Filed: 1974-07-25
Abstract: As the size of turbogenerators to give greater output per unit volume, greater design perfection is required of the cooling system. During the unstable condition provoked by a fault between phase conductors or between phase and earth, dangerous overheating can occur within the generator. In this machine the rotor is circular, with longitudinal grooves which lie between the poles, and with windings lying in those grooves. Damping is provided to counteract the unstable conditions by longitudinal conductors of low resistance which are extended in a radial direction in such a way that their extremities can be connected together.
