Title: Liquid fuel injection pumping apparatus
IPC: F02M41/14
Filed: 1980-01-02
Abstract: A liquid fuel injection pumping apparatus includes a rotary distributor member 12 housed in a sleeve 11 mounted in a body 10. The distributor member is movable in an axial direction and mounts a pumping plunger 15 in a transverse bore 14. An inclined surface is formed on the plunger for co- operation to limit the outward movement of the plunger, with an inclined surface 34 on a part in the form of a strip 27. The strip rotates with the distributor member but is restricted against axial movement. Hence axial movement of the distributor member varies the amount of outward movement of the plunger and hence the amount of fuel which can be supplied by the apparatus. <IMAGE>

Title: Beam waveguide feed for antenna
IPC: H01Q19/18
Filed: 1980-07-04
Abstract: In microwave communication systems it is common practice to use a beam waveguide to transmit energy between a waveguide (2) connected to transmitting and receiving equipment located at ground level and a main antenna reflector mounted above ground level. Hitherto the waveguide (2) has terminated in a very large, accurately machined, horn which is necessary to produce a beam having a small angle of divergance suitable for entry into the beam waveguide (6). The present invention proposes that this large (and very expensive) horn be replaced by a relatively small horn (5A) which produces a beam having a relatively wide angle of divergence. By using a concave reflector (22) and a sub-reflector (21) in Cassegrain configuration this widely diverging beam is converted into a more nearly parallel (or a totally parallel) beam which enters the beam waveguide (6) as illustrated. <IMAGE>

Title: Improvements relating to contact breaker assemblies
IPC: F02P7/063
Filed: 1980-07-17
Abstract: A contact breaker assembly for an ignition distributor has the usual arrangement of a mounting plate (1), a movable contact (6) carried by an insulating heel member (3) pivoted on a post (2) upstanding from the plate, and a conductive spring (5) which acts at one end on the heel member and is anchored to the plate at the other. The spring returns the movable contact against a fixed one (7) between cam action on the heel member, and forms an electrical path from the contacts to the anchored end. The plate has upstanding hooked fingers (19) forming a near-complete aperture into which an insulating block, (10) captive on the spring, is jammed to provide the anchorage. A gap (21) between the fingers allows the spring to be inserted and removed. The block carries a tag (13) for trapping a terminal (22) to the spring, and the spring may have a set which will retain the heel member on the post without need for further securing means. <IMAGE>

Title: Concealed Stair Carpet Fitting
IPC: A47G27/06
Filed: 1980-09-25
Abstract: The main right angle fitting is secured to the staircase (where the tread and risers meet) by pinning through holes in the centre of the fitting. The 45 DEG  angle rod is placed at the top of the main fitting and pressed down so that the grooves on the two fittings interlock. This is repeated on the tread but pushed in only two or three grooves to leave a gap between the two curved edges the thickness of the carpet being fitted. The staircarpet should be secured at the top of the stairs and rolled down to the first step. Using a spatula (4" strip of hardboard) the carpet is pushed into the back of the fitting. The roll of carpet is placed on the top step to expose the back of the carpet and the bottom rod. The bottom rod should be pushed in as tight as possible so gripping the back of the carpet. The carpet is then unrolled down to the next step and the same procedure repeated. <IMAGE>
