Patent GB-2030953-A (GB)
Title: Composite containers
IPC: B65D3/22
Filed: 1978-09-27
Abstract: A tubular body for a composite container, having a wall body, the strength of the wall in an area extending around and adjacent one end of the body wall being reduced without removal of material therefrom, and a curl being formed at said one end, a substantial part of the curl including said wall area of reduced strength. In the preferred embodiment the body wall is of fibrous material and the reduction of strength is achieved by indenting at 12 around a plurality of parallel lines adjacent the end of the body. A diaphragm may be bonded across the end of the body and onto the outside of the curl. The reduction of the strength of the end of the body wall enables the curl to be formed with less pressure from a forming tool and hence less likelihood of the tube collapsing during curl formation. Also, the likelihood of the curl formation process splitting a liquid-proof lining which may be provided on the inside of the wall is reduced. The tubular body may be made of plastics material and the reduction of strength effected by partial cutting through the tube wall or by crushing. <IMAGE>

Title: Filtering aqueous slurries
IPC: C02F1/52
Filed: 1978-11-07
Abstract: A method of filtering an aqueous slurry containing a mixture of siliceous gangue together with coal and/or a water-insoluble mineral ore is carried out in the presence of a wetting agent (in an amount of 0.2 to 2.0 pounds per ton [0.09 to 0.88 kg/tonne] based on the solids weight of the slurry) and guar gum (in an amount of 0.05 to 0.5 pounds per ton [0.02 to 0.22 Kg/tonne] based on the solids weight of the slurry). It has been found that the above combination of wetting agent and guar gum reduces the moisture content of the filtration residue more than the additive effect of the two components.
Patent GB-2040797-A (GB)
Title: Sheet-like structure
IPC: C09J7/28
Filed: 1979-02-02
Abstract: A sheet like structure comprises a flexible metal substrate e.g. of aluminium which is impressed so as to have projections on one side and depressions on the other with an adhesive membrane contiguous to it on one side. The impressions in the metal allow it to be readily bent and after bending to lie flat rather than become arched. The invention allows the application therefore of a thin metal sheet, for instance on an outside surface where it will absorb ultraviolet radiation and thus protect the adhesive membrane by which it is secured to the surface to be protected. The adhesive membrane is preferably bituminous, preferably a bitumen-rubber mix and may also comprise a scrim of glass or polymeric fibres.

Patent GB-2066098-A (GB)
Title: Directional solidification process
IPC: C30B11/00
Filed: 1980-12-04
Abstract: A ceramic mould is supported on a stainless steel platform carried at the upper end of a water-cooled tube surrounded by a copper cylinder containing alumina powder of approximately 100  mu m particle size which is fluidized by an inert gas. Metal in the mould is melted by a furnace which surrounds the mould and the mould is progressively withdrawn into the fluidized bed by which heat is extracted and transferred to water cooled coils surrounding the copper cylinder. In a modification, the inert gas is drawn from the fluidized bed by way of a filter and vacuum pump whereby the outlet pressure is reduced to about 1 torr. This reduces the risk of contamination of the alloy and permits re-use of expensive cooling gases.

Patent GB-2081003-A (GB)
Title: Microcircuit fabrication
IPC: H01J37/304
Filed: 1981-07-20
Abstract: The fabrication of a microcircuit by beam lithography requires an economic distribution of processing time between the high resolution portions of the exposure pattern and areas of much lower resolution. At least one ion beam 16 provides the high resolution performance and at least one electron beam 17, 18 satisfies the lower resolution requirement. The beams are independently operable and are relatively inclined for substantial convergence at the substrate 13. The convergence is such that all beams can be scanned simultaneously in a single element area of substrate or in adjacent elemental areas which are presented for exposure in sequence. For registration the substrate is imaged by electron scanning and the positions of registration marks are related in the image to predetermined positions which represent the required position of the substrate. A positional correction signal is derived by observation of image brightness, size and orientation at the predetermined positions. The signal is processed by a computer which holds all positional control and scan control data and instructs the relevant controls. <IMAGE>

Title: Regulating i c engine charge swirl
Inventor: BALL WILLIAM FREDERICK
IPC: F02B31/00
Filed: 1981-08-28
Abstract: A movable sleeve (35) is slidingly mounted in each engine inlet passage (13) as a passage liner, each sleeve having a profiled tongue (37) at its inner end which projects to a variable extent into the bowl (14) of the passage. The disposition and degree of protrusion of each tongue into its associated inlet passage bowl controls the degree of swirl generated in the associated cylinder. Simultaneous adjustment of the dispositions of the protruding tongues (37) of all the sleeves is carried out automatically during the running of the engine in response to variations in engine operating conditions such as engine speed and load. Such adjustment is effected by moving each sleeve linearly and/or rotating it in its associated inlet passage. <IMAGE>
