Title: Method of manufacturing metal plates having a surface texture
Inventor: THAMASETT EBERHARD
IPC: B21C37/02
Filed: 1968-12-19
Abstract: 1,212,930. Rolling. WIELAND-WERKE A.G. 19 Dec., 1968, No. 60479/68. Heading B3M.  A metal plate with a texturized surface is produced by firmly attaching to the plate a layer of lacquer or a foil, and then rolling the assembly between smooth rolls, the lacquer or foil imparting a textured surface to the plate. When lacquer is used, it is poured or sprayed on to the plate, and is then grained or textured while viscous or dry. The texturing of the lacquer may be effected by a composite roller, by sponges, by scratching tools or by incorporating a filler in the lacquer before applying it to the plate. Alternatively, a plastics or paper foil having a desired profile is applied by adhesive to the plate. The lacquer or foil is removed from the plate after the rolling operation.

Patent GB-706904-A (GB)
Abstract: 706,904. Gas turbine plant ROLLS-ROYCE, Ltd. Aug. 16, 1950 [May 17, 1949], No. 13186/49. Class 110(3) [Also in Groups XXVII and XXXIII] Loss of fuel from a fuel system of an aircraft engine power plant is reduced or prevented by permitting lower boiling point fractions of the fuel in a fuel supply tank to vaporize, compressing the vapour of the lower boiling point fractions, permitting the compressed vapour to condense under pressure and delivering the condensate to the fuel system. The application to gas turbine plant is described. The Figure shows an aircraft fuel system including a fuel tank installation comprising normally a number of fuel tanks 10a. In order to prevent loss of fuel by vaporization fuel vapour is withdrawn from the tanks and compressed by a centrifugal compressor 13 and supplied to a heat exchanger 17 where it condenses and then enters a tank 18 from which it is pumped by a pump 20 into a common supply line leading to the fuel system main pump or pumps. When the atmospheric pressure exceeds by a selected value the pressure in the tank 10a a valve 24 opens and allows vapour from the tank 18 to pass back to the tank 10a. It is stated that the necessity for supplying an inert gas to the tanks is thus avoided. A valve 27 is arranged to open when the ambient pressure exceeds that in the tanks by a predetermined maximum. An inert gas may be supplied through the valve 27. Booster pumps 16 deliver fuel to the supply line. A relief valve 19 is provided in the tank 18. The compressor 13 may be driven by an axial or radial flow air turbine supplied with air from a compressor which may be the compressor of a gas turbine if one is employed in the aircraft. The pump 20 may be driven by an air turbine. Alternatively the compressor and pump may be driven by an engine or by electric motors. The heat exchanger may be replaced by delivery pipes cooled by air. The cooling of the heat exchanger may be effected by air at ambient temperature, the flow being induced by the forward speed of flight of the aircraft. The condensate from the tank 18 may be returned to the fuel tank instead of to the common supply line. The tanks may include isolating valves and balancing pipes as appropriate. Specification 608,963 is referred to.

Patent GB-2021070-A (GB)
Title: System for transporting and storing beverages containig carbonic acid particularly beer
IPC: C12L11/00
Filed: 1978-08-08
Abstract: The carbonic acid-containing beverages, particularly beer, must be stored at the utilization location into stationary pressurized tanks (1). The refilling of the tanks (1) with the beverage must be done by tank truck (23). The beverage is introduced into the tank (1) with a pressure gas, particularly carbon dioxide. The tanks (1) have a lining (40) which prevents the liquid from being in contact with the wall. A stationary gas supply (30) is at disposal at the utilization location to draw the beverage out of the tank. When all the beverage has been drawn from a tank (1), this tank just contains pressure gas. When the empty tank must be refilled with the beverage, the pressure gas must be eliminated from the tank (1). Since the pressure gas, particularly the carbon dioxide, is normally heavier than air, it just cannot escape in the warehouse where the tanks (1) are, without being a danger for people entering this warehouse. For this reason, the tank trucks (23) must be equipped with a pressure gas pump (46) and a pressure gas tank (47), thus allowing to recover the pressure gas out of the tanks before or during the filling with the new beverage. Moreover, the tank trucks (23) must be equipped with a "recycling" system allowing to regenerate the recovered pressure gas (48) in order to use this gas again.

Patent GB-2025661-A (GB)
Title: Cutting system for slab-type materials
IPC: B26F1/38
Filed: 1979-07-04
Abstract: A cutting system for slab goods, e.g. synthetic shoe bottom materials has a station 10, where for each slab, a series of measurements are made to determine the largest permissible rectangle for that irregular piece of material. The dimensions are fed to a computerised marker-making system, which, in real time, determines the average of usable material taken from the measurements of all the stacked slabs. A cutting marker is then generated thereby. The slabs are then moved into a cutting area 12, utilizing a belt on which the slabs rest in the measurement station. When the cutting is complete, material is transported to an off-load station 16 where the cut parts are removed from the system. Flow through is. achieved by having three discrete stations working independently so that, while measuring is taking place, cutting may simultaneously occur at the cutting station and prior cut goods can be off-loaded at an off-load station. Multiple cutting systems may be controlled by a single marker-making system. <IMAGE>
