Title: Brake shoe assembly
Inventor: HOWARTH ANDREW WARD
IPC: B61H7/06
Filed: 1982-10-04
Abstract: A brake shoe assembly 1 for a rail vehicle, comprises a backing plate 2 and at least one brake shoe 3 carried thereby, the or each shoe 3 having a multiplicity of teeth 13 formed of or incorporating hard material (e.g. tungsten carbide), the teeth 13 projecting from their shoe 3 and being adapted, in the braking condition, to engage an adjacent railway rail, each tooth 13 being so positioned that no tooth 13 on the shoe 3 is located in front of, or behind another tooth 13 on the shoe 3, with respect to the direction of braking. The avoidance of tooth alignment ensures that each tooth has a braking effect rather than following in a groove ploughed by another tooth. As shown, three shoes 3 (of mild steel) have circular mounting projections (9) fitting holes (7) in plate 2 and secured by weld metal (10). Details of the formation of nine teeth 13 on each shoe are given. <IMAGE>

Title: Radio-Controlled Devices for Use with AC Power Distribution Circuits
Inventor: DOREY HOWARD
IPC: H04B3/54
Filed: 1984-02-13
Abstract: A radio-controlled device for use in a power distribution circuit, typically for tariff-switching, load-shedding of off-peak load-switching purposes, includes a radio receiver having an aerial circuit which includes a ferrite annulus, The device is typically mounted in an electricity meter connected in the power distribution circuit, with the ferrite annulus surrounding one or more wires of the distribution circuit dawn-circuit of the meter, The wire or wires surrounded by the ferrite annulus, which typically extend all over the house or other building in which the meter and the device are installed, therefore serve as an aerial for the radio receiver in the device, thus alleviating the problems which can arise when the device is mounted in a location where radio reception is poor. <IMAGE>

Title: Non-metallic rings for internal combustion engine pistons
Inventor: RUDDY BRIAN LEONARD
IPC: F02B1/04
Filed: 1984-07-30
Abstract: A piston ring (105, Figure 4; 110, Figure 5; 113, Figure 6A) is formed from a plastics material and has a maximum pressure against the associated cylinder of between 0.10 and 1.50 MN/m<sup>2</sup> and preferably 0.50 MN/m<sup>2</sup>. One possible material for such piston rings is polyetheretherketone. The benefits obtained are greater conformability which leads to a reduction in the number of piston rings which need be used for a particular piston. This in turn reduces friction so increasing the performance of the associated engine. Acceptable wear rates and ability to withstand operating temperatures have been found in these piston rings.

Title: Detecting the relative positions of two members
Inventor: TABATA MITSUO
IPC: G01D5/30
Filed: 1984-12-13
Abstract: In a position detecting method, a light beam 103 is radiated onto a position detecting mark 107 on an object 106; the reflected beam 108 through a slit 109, which is vibrated, to a detector 111 where it is detected synchronously with the vibration of the slit 109; thereby detecting the position of the object 106. A fundamental wave component af and a second harmonic component a2f of the detection signal are extracted in the synchronous detection and derivatives of these components af and a2f are calculated to eliminate variations in output level caused by variations in input level while the relation between peak point of the fundamental wave component af and the zero point of the second harmonic component a2f is retained. For example the following derivatives may be used to detect the position of the object: <IMAGE>

Patent GB-2185762-A (GB)
Title: Tentering clip
Inventor: PAULSEN GUNTHER
IPC: B29C55/20
Filed: 1986-11-05
Abstract: A foil stretching machine has clip chain tracks with tentering clips for transverse stretching of a thermoplastics web. Due to the high speeds at which clip chain tracks operate nowadays, an unpleasant noise is produced, especially during opening of the clips, when the web gripping member 2 of a clip strikes against the clip body, apart from the fact that these parts are then subject to considerable wear. According to the invention, this noise and wear is reduced by introducing an elastic body (4) between the clip body (1) and the web gripping member (2). Since this elastic body (4) can be replaceable, it can easily be replaced when worn without need to remove the whole clip chain or individual members thereof. An arrangement in which a block 6 screwed to the clip body 1 and having the elastic body 4 moulded on it by vulcanization may be provided. The web gripping member 2 is maintained in the open (dashed lines) position or in the closed position (solid line) by a spring 3. <IMAGE>

Title: Improvements in positive pressure dough dividers
Inventor: JONES DONALD ALLEN
IPC: A21C5/00
Filed: 1987-06-16
Abstract: Improved dough is obtained by circulating a cooling fluid adjacent a wall of at least a portion of a positive pressure dough divider in contact with the dough to cool the dough. A typical positive pressure dough divider comprises a hopper (14) for dough, and a pair of rotatable sheeting rolls (15) which carry the dough from said hopper (14) into a transfer passage (16) leading to a volumetric measuring chamber (28) inside a rotating body (27) which is adapted to stop or rotate for periods at reduced speed, such that, whilst the measuring chamber (28) is being charged with dough from the said rolls (15), a maximum possible charging time is provided, and to move at greater speeds at other times to provide minimum possible delay between charging operations. The rolls (15) are of sufficiently large diameter, and rotate in opposite directions at such a speed, as to produce or maintain a dough of good gas retaining properties while providing a positive pressure rise along the direction of flow in the passage between the rolls sufficient to charge the measuring chamber or chambers. Cooling fluid is circulated within the interior of the rolls (15) and adjacent the transfer passage (16) to cool the dough moving between the rolls and through the transfer passage. <IMAGE>
