Patent GB-2075410-A (GB)
Title: Door pin remover
IPC: B25B27/04
Filed: 1980-10-09
Abstract: A tool for use with a hammer to remove the pin from a door hinge. The tool comprises an elongated cylindrical stem 4 of circular cross-section, of a diameter sufficiently small to clear the opening at the bottom of the hinge, if such opening is present and, the inner surfaces of the pin receptacle of the hinge. One end of the stem terminates in a flat surface 12 normal to the longitudinal axis of the stem. A head 6 to receive the blows from an impact means is secured in offset fashion to the stem at its other end. The terminal, blow receiving surface of the head is normal to the longitudinal axis of the stem. The head has a circumscribing edge, and the head is secured near a segment of its edge to the stem in such a manner that a portion of the edge of the head in that area does not overhang the cylindrical surface of the stem. The portion of the head opposite the stem may be provided with a wedge-like shape, pointing away from the stem, with a central part of the wedge extremity being cut away in somewhat concave fashion to be used to wedge under and lift up the cap of a pin in a door hinge without slipping. Such tool facilitates removal of door hinge pins and reduces the potential for damage to walls and parts of the door surrounding such hinge, when compared to prior methods and devices for removing such pins. <IMAGE>

Title: Manufacture of optical fibre preforms
IPC: C03B37/018
Filed: 1981-01-28
Abstract: In the manufacture of an optical fibre preform by forming a vitreous coating, preferably composed of silica and one or more dopants, in the bore of a glass (preferably silica) substrate tube, from a gaseous reaction mixture passed through the tube, the reaction mixture is carried by an ionisable gas and the reaction is activated by a plasma produced in the gas by means of a plasma-exciting device maintained in a stationary position around the gas exit end (3) of the tube. The plasma column is swept along the tube by varying the power input to the device (7), while the tube is heated and the gas pressure is kept below 10 Torr, to effect direct formation of a glass layer (12) along the swept and heated region of the tube. Preferred apparatus includes an asymmetrical microwave cavity (4), and a conducting tube (8) surrounding the substrate tube (1), the arrangement being such that the conducting tube and the plasma column (10) form a coaxial waveguide along which a progressive electromagnetic wave, preferably in the H10 mode, is launched. <IMAGE>

Title: Starting enrichment of alternate firing two cycle internal combustion engine
Inventor: SLATTERY GORDON CHARLES
IPC: F02B75/02
Filed: 1983-12-07
Abstract: A two cycle internal combustion engine 10 has at least two cylinders 12, 13 which fire alternately with pressure in one crankcase 17 or 18 at the time there is vacuum in the other. Supplemental fuel flow passages 36, 41 extend from each crankcase and are joined at a common passage 46 connected to the float bowl 30 of the carburetor 20. A normally closed control valve 48 is disposed in the common passage. When the engine is to be started, the control valve is opened so that fuel enters the supplemental and common passage. Initial rotation of the crankshaft 16 causes pressure in one crankcase to force fuel toward the other crankcase, which has vacuum. Further crankshaft rotation reverses the pressures so that fuel is then forced toward the opposite crankcase. Continued engine operation with the control valve open causes alternate fuel flow reversals together with pressurized alternate fuel injections into the respective crankcases, which are independent of the throttle setting. <IMAGE>

Abstract: A dart sharpener consists of two parts (1 and 2) relatively rotatable about a first axis A-A and a sharpening member (3) on a carrier (4) mounted for rotation in the first rotary part (1) about a second axis B-B. The second rotary part (2) and a cylindrical casing (8) secured thereto together constitute the body of the sharpener. In use the tip (43) of a dart is located on the first axis A-A by a dart tip guide (38) on the first part (1), the dart and the sharpener body (2, 8) are held against relative rotation, and the first part (1) is rotated in the body (2, 8) causing the sharpening member (3) which has an abrasive or cutting surface to revolve around and sharpen the dart tip (43). A gear wheel (26) on the carrier (4) meshes with a gear (11) on the second part (2) causing the sharpening member (3) simultaneously to rotate about the axis B-B so that the sharpening surface (30) of the member (3) wears evenly. <IMAGE>

Patent GB-2176860-A (GB)
Title: Positioning toggle mechanism for railway sleepers
Inventor: MARTYN PETER HENRY
IPC: E01B29/13
Filed: 1985-05-31
Abstract: A toggle mechanism has a two link system upper 1, with a pivot 7 at the upper end and lower link 2, an actuator 4 moving substantially perpendicularly to the upper link. The actuator is pivoted and constrained at its outer end in the vehicle chassis and at its inner end at the pivot point of upper and lower links, so that actuator extension causes the links to move in an arc about their common pivot, tending to increase the angle between them. A spring 3 assists this motion whilst keeping the lower rear edge of the lower link in contact with a roller 9 until both links are mutually abutted to prevent further hingeing, whereupon the mechanism moves only in an arc about the upper pivot of the upper link. Thus as the actuator is extended, the lower nose section of the lower link is caused to move firstly in a near vertical manner, approximately in line with the upper link, and after abutment of the links, to move in an arc about the upper link pivot substantially perpendicular to the line of the upper link. <IMAGE>
