Patent GB-2092071-A (GB)
Title: Information printing methods and apparatus
IPC: B41J11/20
Filed: 1981-12-31
Abstract: A circular platen (21) has a first peripheral portion (22) and a second peripheral portion (24) having a radius (25) exceeding the radius (23). The platen (21) is mounted for rotation. A sheet entry gap (28) is provided between the platen (21) and the print head (15) by moving the first peripheral portion (22) into first proximity to the print head (15). A print gap relative to the print head (15) is provided by moving the second peripheral portion (24) of the platen (21) into second proximity to the print head (15). Since the first proximity is larger than the second, jamming of the entering sheet (19) at the print head (15) is effectively avoided. The smaller proximity readily permits realization of whatever small print gaps are typically required by dot-matrix print heads or other printing devices. <IMAGE>

Title: Machine for folding textile sheet materials
Inventor: BURKE ANTHONY BRUCE
IPC: B65H45/04
Filed: 1982-05-15
Abstract: A machine for folding sheets (10) of textile-type materials includes a horizontal conveyor (12) which moves at a constant speed and which receives successive sheets (10) to be folded. The leading part of each sheet (10) leaving the discharge end of the conveyor (12) is floated by means of an air cushion (A) over a unidirectionally drivable, but normally stationary, roller (20), until a predetermined length of the sheet (10) has passed over the roller (20). The air cushion is then removed so that the sheet (10) no longer moves over the stationary roller (20) but develops a hanging fold between the conveyor (12) and the roller (20). When the apex (23) of the hanging fold corresponds to the midlength of the sheet (10), the roller (20) is rotated in the same direction and same speed as the conveyor (12) until the quarter and three-quarter points are opposite a nip defined between a pair of rollers (24, 26), whereupon the latter points are urged into the nip by another air blast (30) to form a second fold. <IMAGE>

Title: Door switch for a poker machine
Inventor: CULLEY EDWARD WILLIAM
IPC: A63F9/00
Filed: 1983-04-29
Abstract: A poker machine (otherwise known as a fruit machine or slot machine) having an electronic door switch for detecting opening of the poker machine door to gain access to the machine mechanism. The electronic switch comprises a transmitter 2 and receiver 3 which are preferably photo-optic devices. The transmitter and receiver are located, one on the door, and one on the cabinet adjacent to the door opening, such that when the door is closed a signal path exists between the transmitter and receiver, this path being broken as soon as the door begins to open. A pseudo- random signal transmitted by the transmitter is compared in the control unit 4 of the poker machine with a signal received by the receiver and if these signals match over a predetermined minimum period of time the control unit will accept that the door is closed and allow normal operation of the poker machine to proceed. A mis-match of the transmitted and received signals will indicate to the control unit that the door is open, and normal operation of the poker machine will be prevented by the control unit. <IMAGE>

Title: Blow moulding bottles
Inventor: GILES GEOFFREY ALAN
IPC: B65D41/56
Filed: 1983-12-07
Abstract: A bottle (10) for a jigger-style closure cap is formed by blow moulding an injection moulded preform, the bottle having a neck portion (14) with a cylindrical part (14A) on which is formed a screw thread 12. The neck portion further includes a flared skirt (20) which carries a ring (18) formed with ratchet teeth (16) adapted for co- operation with complementary ratchet teeth on a tamper proofing ring around the free edge of the jigger cap (not shown). The skirt (20) overlies an intermediate portion (24') which joins the neck portion (14) with the body portion (26') of the bottle. The neck portion (14) is given substantially its final form at the preform stage, whereas the intermediate (24') and body portions (26') are expanded by the blow mouldings operation. The expansion of the intermediate portion (24') brings it into firm engagement with the bottom of the skirt (20) so as to locate the ratchet teeth (16) radially and render the skirt solid with the remainder of the bottle. Alternatively, portion (24') may engage skirt (20) over substantially the whole of its length, and the skirt may be provided with circumferentially spaced apertures, Figures 6, 7 (not shown). <IMAGE>

Title: Means for transmitting brake force
Inventor: CAMPH SVEN ERIK
IPC: F16D65/22
Filed: 1984-11-08
Abstract: Means (7 or 8) for transmitting brake force between a brake activating key and a respective brake shoe (13 or 14) of a drum brake comprises first and second interengaging threaded elements (9, 10 or 11, 12) a relative rotation of which manually or automatically will cause variation of their total length. The remote end surfaces of said means have curved surfaces engaging surfaces on the key (6) and brake shoes (13 or 14). The end surface of each element (9, 12) engaging the respective brake shoe (13, 14) has a curve radius R in one plane which is at least twice the curve radius of the same surface in a further plane perpendicular to said first plane. Axial displacement of shoes (13, 14) is thereby said to be avoided. Various possibilities are illustrated. As shown shoulder surfaces (19, 20) are provided to prevent relative sliding in the plane of Fig. 3. In Fig. 6 curve radius R is longer than the active length of the respective force transmitting means. In Figs. 7,8, R is increased indefinitely - the surface at the brake shoe theoretically become cylindrical although is practical use there is slight curvative. <IMAGE>

Title: Air gun pellets
Inventor: VARDON HENRY LANCELOT
IPC: F42B6/10
Filed: 1985-08-03
Abstract: A pellet for an air gun comprises a head 1 and a tail 2, the head being composed of a relatively dense material and the tail being composed of a less dense material, with the head and the tail each dimensioned so that, in use, they contact the bore of the air gun from which the pellet is fired.
