Title: Auxiliary cold-starting carburettor for i.c. engine
IPC: F02M1/04
Filed: 1979-01-22
Abstract: The carburettor includes a plug type throttle valve 23, a fuel metering needle valve joined to the throttle valve 23 by an arm 45 and a thermostatically controlled mechanism controlling closing movement of the two valves, which includes a catch 52 which engages the arm 45 during cranking and for a predetermined time after the engine begins running on its own. Hence the two valves are held open until the catch is released at the end of that period whereupon the two valves move together freely to a partially closed location from where they move progressively in the closing direction as the engine warms up. The catch is released by deformation of a bimetallic element 55 which is heated by heat remitted by a positive temperature co-efficient element 54 to which the output of an engine driven alternator is applied. <IMAGE>
Patent GB-2015336-A (GB)
Title: Article supporting and display device
IPC: A47F5/02
Filed: 1979-04-23
Abstract: This invention relates to a device for supporting an article having an aperture therein and comprises a stand having a plurality of arms extending radially outwardly from an upstanding column. Each arm has an upstanding outer end portion and has associated therewith a rod arranged to co-operate with the corresponding arm to provide a loop. Each rod is movable longitudinally relative to the outer end portion of the corresponding arm so that an article can be located on the arm and suspended thereon.

Patent GB-2045669-A (GB)
Title: Method of microdrilling metal workpiece using a power laser
IPC: F02M61/16
Filed: 1980-02-13
Abstract: A laser microdrilling method uses a power laser beam (3) the action of which causes solid workpiece metal (1) to be transformed into both liquid and vapour phases. In order to improve the surface finish and dimensional accuracy of a hole (4) formed, the workpiece (1) is heated to a temperature sufficient to cause both the liquid phase formed directly by the action of the laser beam (3) and the liquid phase caused by the condensation of the vapour phase on the wall of the hole being formed (4), to be maintained in the liquid state for a period of time long enough to permit the uniform spreading of these liquid phases over the wall of the hole (4). For a plate workpiece, the ends are clamped to conductors from a high frequency source (9). For a fuel injector, the tip is covered by a bell connected to the electrical source. A plasma torch may be used during and after laser drilling to improve the bore quality. <IMAGE>

Title: Improvements in or relating to supports for the spine
IPC: A61F5/02
Filed: 1980-05-27
Abstract: A support for the spine comprises a belt having laterally spaced spinal support members 20 disposed in respective closed pockets in the belt. Each member 20 comprises a plurality of adjacent parts (e.g. 20b, 20c) which are hinged together and are so shaped so that they can pivot relative to each other in a forward sense from a datum position but not in the rearward sense from that position.
