Title: Scan converter apparatus
Inventor: LEAVITT STEVEN C
IPC: H04N7/01
Filed: 1984-07-16
Abstract: Apparatus for interpolating data obtained along radial scan lines (e.g R2), so that it can be displayed at display points (e.g DP) arranged in orthogonal rows and columns, by recursively adding stored values to derive signals (RERR<1>, CNT) indicative of the radial position of each display point along the radial data lines and its angular position between the radial data lines. Interpolation is done along radial lines adjacent a display point to derive first and second intermediate interpolated values, and these values are interpolated so as to derive the final data value for the display point at its angular position. Alternatively, the intermediate interpolated values can be attained by angular interpolation and the final data value by radial interpolation. The invention is particularly concerned with the recussive derivation of the angular positions of display points. <IMAGE>

Patent GB-2150256-A (GB)
Title: A method of stabilising separated laminar boundary layers
Inventor: LURZ DR WERNER
IPC: B64C21/02
Filed: 1984-11-15
Abstract: Separated laminar flow boundary layers are stabilized by delaying a transition into a turbulent flow and by reducing the size of the laminar boundary layer separation zone downstream of a disturbance in the surface contour of a body in the flow, such as a backward step in the body surface, e.g., where sheet metal layers overlap in the surface of an aircraft wing. This purpose is accomplished by suction inlets in the surface just upstream of the disturbance and blowing outlets just downstream of the disturbance and by a flow channel interconnecting these inlets and outlets. Passage of a portion of the flowing medium through these passages is automatically assured due to a pressure differential between the inlets and outlets.

Patent GB-2159766-A (GB)
Title: Printing on spark plugs
Inventor: COSSON COLIN
IPC: B41F15/08
Filed: 1985-05-20
Abstract: Spark plug insulators (2) are mounted vertically around the edge of a horizontal turntable (1). A screen printing head (20) is arranged horizontally above a print transfer drum (41) that is rotatable about a horizontal axis (42). Pads (44) of a relatively hard resilient material are disposed about the drum. The printing head (20) is brought down into contact with the top, horizontal pad on the drum, so that the pad takes up ink, and the drum is then rotated to a vertical position. As the turntable is rotated, a pair of rollers (10) are urged by a cam surface (13) into contact with the insulator, rolling the insulator along the vertical print transfer pad to take up ink from the pad. The ink is ceramic based in a thermoplastic carrier. The printing head (20) is heated by passing current through a conductive screen so as to render the ink flowable, the print transfer pads (44) being heated to maintain the ink flowable until it is deposited on the insulator (2). <IMAGE>

Title: Method and apparatus for treating plant material
Inventor: SHAW JOHN CHARLES MICHAEL
IPC: A01G31/04
Filed: 1986-06-13
Abstract: A method and apparatus for making animal feedstuff comprising germinated grain comprises mixing the grain with a water absorbent polymeric material, such as a cross-linked acrylamide polymer, and water and employing the polymer as a source of water for germination of the grain. Preferably, grain and polymer are soaked in water before mixing. The grain and polymer mixture is formed into a layer on a conveyor having perforations to admit air to the layer of plant material.

Title: Distributor-type fuel injection pump for internal combustion engines
Inventor: HOFER GERALD
IPC: F02M55/00
Filed: 1987-02-20
Abstract: In order to achieve a uniform static pressure in the pressure lines (31), by way of which an internal combustion engine is supplied by a distributor-type fuel injection pump, during the injection intervals the pressure lines (31) are relieved by way of a compensating port (43) and a valve (51) the suction chamber (8). During starting when air is present in the pump or the pressure lines 31, the valve (51) prevents relief, o that the pressure level in the pressure lines (31) at the end of each delivery stroke of the pump piston (3) is maintained and any enclosed air is compressed to injection pressure and thereby purged from the pump working chamber and from the pressure lines by being delivered with the fuel. After start-up pressure builds up in the suction chamber (8) and moves the valve (51) to a position connecting the compensating port (43) to the suction chamber (8). The valve may be in the form of a spring loaded ball valve or be constituted by the control sleeve (38). <IMAGE>

Title: Reflective cavity heat source
Inventor: THORNTON JACK
IPC: G01N25/00
Filed: 1988-11-02
Abstract: Especially for thermal shock test equipment where a very high heating rate is to be applied to a test sample, a heat source comprises an internally reflective enclosure containing one or more heaters, e.g. quartz halogen lamps 211. A relatively small aperture 28 in the wall of the enclosure leads to the test sample 29 supported on a sliding tray 212 so that it can be safely entered into the heating position. The enclosure forms a kind of "integrating sphere" (known in the context of scientific apparatus for measuring small amounts of received optical radiation) but combined with the internal heat source (lamps) forms a powerful source of concentrated heat (Figure 4). The source may be a quartz bulb silver plated over all but a 1 cm diameter circle and containing one or three resistance filaments. <IMAGE>
