Patent GB-2112529-A (GB)
Title: Alternating-current tachomoter
Inventor: FREITAG ARMIN
IPC: G01P13/04
Filed: 1982-11-26
Abstract: The invention relates to an alternating- current tachometer whose output is in linear dependence in amplitude and frequency upon the rotation rate and the recognition of direction of rotation is achieved within a very narrow error range in the region of the zero point. A multi-pole winding of meander form, arranged in the air gap in a magnetic flux circuit including magnetic yokes 1, 2 and magnet 3, on non- magnetic material 8 is energised by a magnetic flux of varying intensity. The variation of the magnetic flux is here achieved by a constantly changing maximal and minimal coupling to the winding, the slot pitch corresponding to the pole pitch. The alternating magnetic couplings are achieved by appropriate grooving on the magnetic yokes of the rotating energiser circuit in the region of the air gap, whereas the winding is stationary. The type of winding and the winding pitch or interval determines whether a single phase or a selected multi phase A.C. output is produced. The direction of rotation may be determined from the polarity of the rectified D.C. voltage. <IMAGE>

Title: Interactive video game arrangement
Inventor: ALLES HAROLD GENE
IPC: H04N7/173
Filed: 1983-05-05
Abstract: Typical video game systems include, at each game location, a digital microprocessor packaged with a memory for storing the program instructions of a particular video game. The video game scenes are usually displayed on the screen of a conventional television receiver. Using position controllers, one or more players who are collocated at the game location, may actively compete in the video game. To avoid the cost of such special equipment at the microprocessor, memory and the position controllers, the invention contemplates sharing certain common equipment which may be located at the head end of a cable television system. The potential game player tunes a conventional TV receiver to a video game channel, the TV receiver being coupled to a CATV cable. Thereafter, the game player may place a telephone call to the common head end equipment, responsive to which the player may be connected to the video game. The player may then use the common telephone to competitively interact with the video game being displayed on the TV receiver. <IMAGE>

Title: Cathodoluminescent display arrangements
Inventor: NIXON RALPH DESMOND
IPC: H01J31/12
Filed: 1983-07-13
Abstract: O A display arrangement utilises a fluorescent screen 3 to provide readily alterable bright displays. The arrangement can provide a fairly large display surface, but can be of very small thickness. It contains electron emissive cathodes 5, and field electrodes 7 positioned closely adjacent to the cathode to control the emission of free electrons. Electrons which are freely emitted are accelerated to a mesh electrode 4 which is held at a modest positive voltage. A fluorescent screen 3 having a positive potential of several thousand volts is positioned closely in front of the mesh electrode. The preferred embodiments of the invention, a number of separate cathodes and/or separate field electrodes are provided, so that selected regions of the screen can be illuminated to provide desired display patterns. Individual regions of the screen can be switched on and off (i.e. rendered bright or dark) by the application of very low switching potentials to the field electrodes and/or the cathodes.

Title: Flexible ladders and stand-off members for such ladders
Inventor: ASHTON JOHN MICHAEL
IPC: E06C1/56
Filed: 1983-09-09
Abstract: The flexible ladder 10 includes a pair of flexible stiles 12 and a number of rungs 14. A pair of stand-off brackets 22 are secured together around the stile 12 on either side, and at either end of each rung. Each bracket 22 includes a wide foot 56 which bears against the building to hold the rung away from the building and to hold the rung steady. The rungs also cooperate with the stand-off brackets to prevent relative rotation. The force exerted by the bracket on the building is increased when a person is climbing on the ladder and thus the arrangement becomes more stable in use. The ladder can be folded to a compact storage position in which the wide portions of the brackets lie adjacent to narrow portions of the bracket or in which those portions overlap each other. <IMAGE>

Title: Container having a metal body attached to a polymeric component
Inventor: ASHLEY ROBERT JOHN
IPC: C09J151/06
Filed: 1984-11-21
Abstract: A container for an aqueous or non-aqueous product, such as a paint, has a tubular metal body with at least one component of a polymeric material attached thereto, such as pivot lugs 28 for a carrying handle or a top ring 141 for receiving a conventional plug type lid or a base member 29 of the container or a flanged top member for a rectangular container, the top member carrying a handle and spout (Fig 4). The polymeric component or components is or are attached to respective bare metal portions of the surface of the metal body 10 by means of an adhesive, essentially composed of a polyolefin chemically modified to increase the content of polar groups, in such a manner that in use the adhesive joint between the surfaces is subjected to a shear mode of loading. The polymeric material of the components may be a propylene based polymer or copolymer or a polyamide (nylon). Preferably the surface of the metal body is coated with a protective lacquer except where the components are attached. The metal may be heated to a temperature above the melting point of both the polymeric material and the adhesive to form the bond, the heating being effected by spin-welding. The pivot lugs may be attached inside a recess (30, Fig 2A). The content of polar groups is increased by addition of at least one of maleic anhydride, maleic acid and acrylic acid, the polyolefin being polypropylene or a copolymer of propylene and ethylene. <IMAGE>

The token, star and union operation cells are arranged so that regular expressions may be mapped in electronic circuitry on a one-to-one basis in the same sequences in which they are written algebraically. Subsidiary connections or additional design exercises are not required. <IMAGE>

Title: Plastics wear strip for conveyor chains
Inventor: DAMKJAER POUL ERIK
IPC: B65G21/22
Filed: 1986-06-13
Abstract: A wear strip (1) for chain conveyors with plastic chains (2) is made from a surface hard plastic material e.g. polyester which can be made even more surface hard by intermixing of glass fibres and be produced by injection moulding. It is thus avoided that dust and foreign particles become embedded in the surface of the wear strip and thus cause the plastic chain to wear quickly. If so desired it is possible in the material to furthermore incorporate wax whereby the friction with the plastic chain and the foreign particles, respectively, may be reduced. The wear strip may be made of units which link together in the manner of a chain. <IMAGE>

Title: Drink cooler
Inventor: PAXMAN NEIL ERIC
IPC: B67D1/08
Filed: 1987-04-10
Abstract: A drink cooler (1) has a coolant tank (3) and product tank (2) which carries drink. The coolant tank (3) feeds coolant through the product tank (2) in order to cool the drink. A combined product/coolant pipe (21) comprises a central pipe (23) which communicates with the product tank, and a coolant line (24) which communicates with the coolant tank (2). Drink within the product/coolant pipe (21) is maintained at a desired temperature due to heat exchange between the drink and the coolant. The cooled drink is dispensed through a tap (22). By keeping the drink cool to the point of dispense, fobbing may be minimized and the drink may be served cooler and quicker than with known apparatus.
