Patent GB-2094653-A (GB)
Title: Alternately operated sets of filters in filter tank
IPC: B01D29/00
Filed: 1981-07-21
Abstract: Parallel filters (14) are alternately communicate with manifolds (66 or 68) and valve (130) passes filtrate selectively from the manifolds to a pump (190) and discharge duct (202). When sufficient liquid has been fed to the filter tank, the pump (190) is operated to draw filtrate from one of the manifolds (66, 68). When a vacuum gauge (153) senses a reduced flow rate from one manifold, the timer controlled valve (130) moves to draw filtrate from the other manifold and actuate valve (146) to cause a pulsed backflow in the first filter set to clean the filter media. If the liquid level in the tank falls, valve (208) diverts the discharge from pump (190) back into the tank. Sludge is removed from the bottom of the tank by conveyor (234). The filter units, Figure 4, comprise filter cloth covering expanded metal panels (42) fitted onto a manifold coupling (64). The filter unit is sealed against the manifold by ring seal (94) compressed under the weight of the filter unit or by clamps for the filter unit. The external surface of the filters can be fitted with flat or curved louvres. A magnetic bar can be provided at the top of the filter units so that they can be removed by a magnetic hoist. A valve (100) in the manifold is opened automatically when the filter is fitted. <IMAGE>

Title: Stamped plastics sheet
Inventor: JINNO KATSUSHI
IPC: B29C48/08
Filed: 1982-04-13
Abstract: To produce a stamped sheet of thermoplastics material, film-shaped molten thermoplastics material is supplied from a die (d) to a pair of stamping rollers (r, r') disposed in a bath (v) containing liquid refrigerant (W), such as water. The thermoplastics material passes between the rollers where they engage and is thus stamped by virtue of at least one of the rollers having an uneven outer wall corresponding to a configuration and/or pattern of characters, figures, symbols, pictures or the like. The stamping occurs before the thermoplastics material has solidified to the core, i.e. the core is soft, although a solidified skin layer has formed on the surface of the material. A sheet produced by the method has ribs (1) arranged at regular intervals and extending in a predetermined direction. Each rib is divided by a plurality of hill parts (2) to form individual peak parts (3). The configuration of the sheet means that forces can be absorbed by the peaks (3) to give the sheet an excellent shock absorbing quality. <IMAGE>
