Title: Electrical switchgear of the rotating arc, double-break type
IPC: H01H33/18
Filed: 1980-05-12
Abstract: In a contacts closed position of the switchgear a pair of contact arms 6 and 10, which are electrically connected to respective conductors 3 and 4, engage the ends of a main contact bar 17 such that current flow occurs through the switchgear by way of conductor 3, contact arm 6, contact bar 17, contact arm 10 and conductor 4. Upon movement of the contact bar 17 in the direction of arrow 31, the contact bar disengages from the contact arms 6 and 10, and an arc is drawn between each contact arm and a respective arcing electrode 23A, 23B. A common field coil 27 has its ends electrically connected to the arcing electrodes respectively, such that the arcing current flows through the field coil 27 to create a magnetic field which causes the arcs to rotate and become extinguished. An insulating barrier 24 separates the electrodes 23A and 23B to prevent the arc from being transferred directly across the contact arms 6 and 10. <IMAGE>
Patent GB-2051303-A (GB)
Title: Fibre-reinforced composite shaft with metallic connector sleeves
IPC: B29C70/86
Filed: 1980-05-28
Abstract: A tubular fibre reinforced composite shaft integrally incorporates a metal sleeve or connection at the end. Initially a metal sleeve 14 having longitudinal grooves is positioned upon a segment of a mandrel. The grooves also taper in the longitudinal direction. Fibrous material bearing a non-solidified resinous material is applied around the mandrel and around the grooves in the sleeve. An annular lock ring 30 having radially inwardly projecting ridges is inserted axially over the fibrous material whereby the ridges press the fibrous material into the grooves in the sleeve. The resinous material is then solidified to form a tubular composite shaft whereby a torsion-transmitting connection is made with the sleeve. <IMAGE>
Patent GB-2084973-A (GB)
Title: An integrated process for the production of methanol and ammonia
IPC: C01B3/02
Filed: 1980-10-07
Abstract: The process comprises the steps of subjecting a gaseous hydrocarbon feed to primary reforming with steam to produce a methanol synthesis gas containing H2 and CO, producing methanol from this methanol synthesis gas in a synthesizer, subjecting a purge gas extracted from the methanol synthesizer to secondary reforming with steam and air to produce an ammonia synthesis gas containing H2, N2, CO and CO2, subjecting this ammonia synthesis gas to high temperature shift conversion for the purpose of reducing its CO content, and thereafter passing the CO-impoverished ammonia synthesis gas through a series of steps to remove carbon oxides, the resulting ammonia synthesis gas then being fed to an ammonia synthesizer (26). Removal of oxides of carbon involves absorption of CO2, an additional methanol synthesis and methanation. Alternatively, if the gas stream leaving the high temperature shift converter is subjected to a low temperature shift conversion, removal of oxides of carbon can simply involve CO2 absorption and methanation.

Title: Gaming apparatus having manually controllable operating speed
IPC: G07F17/34
Filed: 1981-01-26
Abstract: An amusement or game device of the type which has one or more indicia-bearing rotatable reels which are rotated upon initiation of play by a player has a main drive mechanism which permits the player to vary the initial rotational speed of the reels in direct proportion to the speed in which an associated operating handle is pulled. A supplemental drive mechanism is included for increasing the speed of the reels if the player fails to pull the operating handle with sufficient force to rotate the reels at a predetermined minimum speed. The device also includes an improved indexing means for stopping the reels in accordance with the operation of the game device. The game device also includes means for absorbing excessive energy that may be provided by a player pulling the operating handle with extraordinary speed or force. A mechanism is also included for providing slight resistance to movement of the reels subsequently of enablement of the game device and immediately before pulling of the operating handle, during which time the reels are otherwise free to rotate since neither the main drive mechanism, the supplemental drive mechanism nor the indexing mechanism is engaged at this time.

Title: Method and apparatus for one line dropout compensation of color television signals
IPC: H04N9/888
Filed: 1981-03-24
Abstract: Dropout compensation of composite color television signals is described, in which both the luminance and chrominance components of a dropout compensation signal are derived from the same portion of the original colour television information signal immediately preceding the dropout. One horizontal line of the television signal is continuously stored in a memory 2,3,4. When a dropout occurs, the last received original television signal line is circulated in the memory. The length of delay of the stored chrominance component is controlled line-to-line in response to the phase of the color burst synchronizing component. The length of delay of the stored luminance component is controlled on consecutive lines in response to the horizontal line syn- chronizing component. The respectively delayed chrominance and luminance components are combined into a composite dropout compensation signal which is applied when a dropout is detected. <IMAGE>

Title: Heat transfer
Inventor: BOWEN JOHN LAURENCE
IPC: B41M5/035
Filed: 1981-07-13
Abstract: A sublimation dye stuff heat transfer that can be applied using heat and pressure to a range of substrates normally having no affinity for the dye stuffs and therefore unable to be transfer printed by this method has a coating of hot melt adhesive applied exactly over the sublimable design, the adhesive having an affinity for the dye stuffs, thus providing on application of the transfer, a thin and flexible film on the surface of the substrate which can take up the sublimation dye stuff. A layer of polyester flock staples may be placed between the dye stuff and the hot melt adhesive using a secondary hot melt adhesive of low strength to support over the design area to permit the transfer to be applied to dark substrates or to give a raised effect to the transfer design.

Title: Radar systems for airborne vehicles
Inventor: VOLES ROGER
IPC: F42B15/01
Filed: 1982-05-25
Abstract: An airborne vehicle in the form, of a terminally-guided sub-munition has a wing or wing-like assembly (100) which can be stowed lengthwise of the body and deployed, for flight, transversely of the body. An antenna array is mounted on the wing surface to extend across the undersurface thereof and is capable of generating a fan beam pointing forwardly of the sub-munition. A target on the ground is identified in the search phase by scanning the fan beam in azimuth and the sub-munition may then be pitched over into a dive to approach the target, so detected, in the terminal phase. The detected target may then be tracked using a linear antenna array conforming to the nose of the submunition. Scanning of the wing-mounted antenna can be achieved by rolling the vehicle, by turning the vehicle in azimuth, or by rotating the wing itself in azimuth.
