Patent GB-2123089-A (GB)
Title: Gear pump
Inventor: HAUPT FRITZ
IPC: F04C15/00
Filed: 1983-07-08
Abstract: Two pumping gear-wheels (24, 26) are mounted in a housing (10) and each of them has its own motor (40 or 42). The motors may be electric, flange-mounted on the ends of the housing remote from each other, and connected to the associated gear-wheel through a coupling (36 or 38). Thus, each gear-wheel draws power from the associated motor and only a comparatively slight difference of power, if any, is transmitted from one gear-wheel to the other. Accordingly, the gear-teeth are loaded substantially only by forces and moments which are caused by the difference in pressure between the working-fluid inlet (12) and outlet (14), Fig. 2. <IMAGE>

Patent GB-2188427-A (GB)
Title: Inclination sensor
Inventor: RYAN PAUL THOMAS
IPC: G01C9/20
Filed: 1986-03-27
Abstract: An inclination sensor is disclosed which includes a capsule 15 containing a conductive liquid 17 which forms a liquid pendulum and having first and second resistive tracks 11, 13. In a first measuring configuration the terminals A, B of track 11 are connected to positive and negative voltages respectively and the terminals C, D of resistive track 13 are connected together, to form a sensing electrode. The voltage at terminal B is then adjusted so that the voltage at common electrode C, D, sensed through the conductive liquid 17 is adjusted to be zero. The ratio of voltages at terminals A and B is then related to the position of the conductive liquid 17 relative to the resistive track 11 and thus of the inclination of the capsule relative to horizontal. In an alternative measuring configuration, the roles of the resistive tracks 11, 13 are reversed, to allow the sensor to measure angles in a different angular range.

Title: Device for drawing off sheets from a sheet stack
Inventor: ASCHER FRANZ
IPC: B65H3/08
Filed: 1986-05-30
Abstract: Sheets are separated from a stack by two parallel take-off rolls (17, 19) one above the other, the sheet stack (11) being urged resiliently upwardly against the lower take-off roll (19). The lower take-off roll (19) is freely rotatably mounted on a pivotable control rail (23) and urged by spring (27) against the driven, upper take-off roll (17). As long as no sheet (13) is introduced between the take-off rolls (17, 19), the lower take-off roll (19) separates sheets from the stack (11) and transfers them to between the take-off rolls (17, 19), but when the uppermost sheet (13) is introduced between the take off rolls (17, 19) the control means moves the lower take-off roll (19) away from the upper take-off roll (17). The take-off device is capable of withdrawing from the sheet stack even sheets sticking to one another or stapled to one another. The control means may comprise dogs (47) on rail (23) engaging in circumferential grooves in the upper take-off roll (17). <IMAGE>

Title: Marine propeller
Inventor: BOURNE DENNIS GEORGE
IPC: B63H1/26
Filed: 1986-09-03
Abstract: A marine propeller comprises a plurality of multi-foil blade assemblies with forward sweep, each assembly having foils set at increasing pitch angles and set in positions which ensure that the flow from the pressure face of each foil except the rearmost passes over the succeeding foil to produce lift. All foils can develop reaction thrust and the primary foil is able to develop lift when it becomes unstalled as forward speed increases. The narrowness of the foils is stated to avoid or minimise cavitation. The foil tips may be cut square in section, and conform substantially to the shape of a helix. The tips may also be covered by anti-vortex plates. Alternatively the tips may be cut square in section, and covered by a cylindrical shroud. Details of the theory behind the design of the propeller are disclosed. <IMAGE>
Patent GB-2197064-A (GB)
Title: Simulated solid fuel gas fires
Inventor: CHESWORTH ARTHUR
IPC: F24C3/00
Filed: 1986-11-01
Abstract: A simulated solid fuel gas fire has a first aerated gas burner (13) and a second non-aerated or lightly aerated gas burner (14) for producing decorative flames about a non-burning fuel representation. A control valve (25) provides a plurality of heat output settings to both the burners. At lower heat outputs the fuel representation is not heated sufficiently to glow red. At lower settings, therefore, an increased gas supply is provided to the second burner so that the decorative flames are larger. At higher settings the fuel representation glows red, so that a more realistic burning appearance is given. At these settings the supply to the second burner is reduced so that the decorative flames are smaller. The valve (25) is arranged to provide this inverse gas flow relationship to the two burners as the overall heat setting is altered. <IMAGE>
