Title: Process for the Manufacture of a Gymnastics Mat
IPC: B29C44/56
Filed: 1979-11-28
Abstract: In a process for the manufacture of a gymnastics mat a polyester foam with a density of the order of 30 kg/m<3> is produced by chemical curing without moulding, and is cut up into blocks having a thickness of about 100 mm, and these blocks are subjected to compression under heat so as to reduce their thickness to about 20 mm, the cells remaining open and the density being increased to a density in the range of from 150 kg/m<3> to 180 kg/m<3>. The mats produced are resistant to rupture and tearing and yet relatively light. They are very supple and skid proof, and do not absorb the movements of the gymnast but are able to protect him when landing.

Title: Method and apparatus for electric space heating
IPC: F24D11/00
Filed: 1980-04-01
Abstract: The invention provides a method of and an apparatus for centrally heating space, using an electricity supply as the primary energy source. Heat is stored in a fluid storage medium e.g. water during a period of time (e.g. at night in the so-called "off- peak" hours) when there is a relatively little demand on the electricity supply. The heated fluid is pumped from the store (11, 12), through heat exchangers (21, 22), during a subsequent period of time (e.g. during the day in the so-called "peak" hours), when there is a relatively high demand on the electricity supply. The heated fluid is pumped through the heat exchangers in response to a heat demand which emanates from the area to be heated. If the demand cannot be met by the heat in store, additional heat is provided by heating the fluid externally of the store (via a heating unit (25)) and pumping the additionally heated fluid directly into the heat exchangers. <IMAGE>

Title: Aerial Gunnery Target
IPC: F41J9/10
Filed: 1980-05-28
Abstract: An aerial gunnery target to be towed by an aircraft at high speeds comprises a multiplicity of strands or cords 34 such as twisted and plyed polypropylene lines. Each strand is secured at the forward end on a towing frame having various configurations which include circles, bars, radial extensions, hexagons and triangles. The towing frame is pulled by a conventional towing cable and may have arms that extend outwardly upon deployment by aerodynamic forces, or may be rigid. The cords extend backwardly to a terminal point, such as an analogous frame or a confluence point, such as a ring. The elongated cords avoid the coupling of vibratory motion from one cord to another which results in the oscillatory flapping of targets constructed of conventional fabric, and are provided in an array such that they do not create aerodynamic lift and fluttering when being towed. They prevent the erratic flight frequently encountered in conventional rigid targets when they are damaged by gun fire. <IMAGE>

Title: Reciprocating external combustion engine
IPC: F01K21/04
Filed: 1980-12-19
Abstract: Energy is transferred to air acting as a working gas by injection into the air of liquid water at a high temperature and pressure. The liquid water from heat-exchanger H is injected either directly at 51 into the cylinder 5 or into a preliminary mixing chamber. The water acts as a heat- transfer medium for heating the air. Spontaneous vaporization of the liquid water on injection increases the pressure of the air which drives the piston before being exhausted. The exhaust water is separated from the exhausted air in tank T and recycled. The cylinder is scavenged and refilled with a fresh charge of air from the rod end C of the cylinder which acts as an air compressor. <IMAGE>

Title: Panoramic locating apparatus
IPC: G01S17/86
Filed: 1981-01-19
Abstract: Movement within a scene is detected by scanning the scene in elevation and azimuth, 6,4,3, imaging each part of the scene onto two detector rows 12, 13 which are staggered with respect to one another in the azimuthal direction and which have an identical number of detector elements, delaying the output of the detector rows 12 which detects first of all a specific instantaneously-depicted picture detail and comparing it with the non-delayed output of the second detector row 13. A difference signal which is different from zero then indicates movement within the field of vision of the panoramic locating apparatus. The angular position of the moving object can be obtained by measuring the angle of elevation and angle of azimuth of the optical axis 6 at the instant of the recognition of the moving object.

These devices are connected to respective level comparators which, when the connected devices sense predetermined feed pressures, provide input signals of a control circuit to initiate sequencing control steps thereof. The control circuit controls solenoid feed valves for the hydraulic cylinders (20, 21). <IMAGE>
Patent GB-2095090-A (GB)
Title: Prefabricated steaks
IPC: A23L13/00
Filed: 1981-03-19
Abstract: Prefabricated steaks are produced from parts of animals not normally used for steak meat and from small animals by a process comprising: cutting muscles from the animal with the grain of the meat running parallel to the longer dimension of each strip; dicing the strips into rectangular bricks, with the grain of the meat lying parallel to the longer side of the bricks; introducing the bricks into an extruder whilst aligning the bricks with their longer axes parallel to the direction of extrusion and compacting the bricks into a solid meat log; and cutting the log transversely to form steaks wherein the grain of the meat lies along the shorter axis of each steak. For example the muscles are put through the lacerator (see drawing) and into the dicer, from which the pieces pass to the blender. The arrows show diagramatically the way in which fat and gristle and additives are added. The blended materials are passed through a pipe containing directional deflectors in the form of vanes which make sure that the strips of meat are lined up in the correct way so as to retain their grain running longitudinally. The material is forced through the extruder and after extrusion the meat is blast frozen and cut. <IMAGE>

Title: A thermal processing system for semiconductors and other materials using two or more electron beams
Inventor: AHMED HAROON
IPC: H01L21/263
Filed: 1982-05-26
Abstract: In apparatus and methods for thermal processing of semiconductors and other materials in order to change their properties, two electron beams are directed from opposite sides of e.g. a silicon wafer which is thermally isolated as far as possible. By combining the heating effects of the two beams the temperature distribution that is required to modify the wafer is achieved. In one embodiment, one beam is scanned rapidly in a raster over the whole wafer to heat it while the second beam is formed into a line and scanned to provide further heating. This combination is used to modify a poly-crystalline silicon film into single crystal material. In other embodiments the second beam is formed into a spot a square or other shape to obtain the desired temperature distribution. <IMAGE>
