Patent GB-2221013-A (GB)
Title: An elastic coupling
Inventor: HANKE WOLFGANG
IPC: F16F15/134
Filed: 1989-06-20
Abstract: In an elastic coupling of disc construction, in which one coupling half 7, 8 encloses the other 6 by forming a fluidtight inner chamber 11 which can be filled with damping medium, are disposed displacement chambers 16 having throttle gaps 15. The enclosed discs 6 are divided on the outer circumference by partitions 17, between which radial surfaces on the discs 6 dip according to a determined torsion angle. As a result there is achieved a damping of torsional oscillations which can be better adapted to the load conditions of the coupling, in particular a better adaptation to the no-load and full load conditions of the engine. As a result it is possible to have stronger damping in the resonance region by the resistance to flow in the displacement chamber being increased and by also providing partitions with a labyrinth seal which is effective to control the flow of damping medium radially inwards in dependence on the relative torsion angle of the coupling halves.

Title: Annular cutter
Inventor: TARGETT DERRICK RUSSELL
IPC: B23B51/04
Filed: 1989-08-17
Abstract: The cutter has a generally cylindrical hollow main tool body and drive connection means at one end. Cutting means at the other end has a plurality of spaced teeth defining cutting edges including inner and outer cutting edges. Each tooth has only an inner cutting edge or an outer cutting edge. For each tooth A having an outer cutting edge the portion corresponding to the inner cutting edge is at least partially removed, and for each tooth having an inner cutting edge, the portion corresponding to the outer cutting edge is at least partially removed. Such removal can be by grinding chamfers or removing the outer cutting edge entirely in the initial gullet grinding step. <IMAGE>

Title: Bale wrapping machine
Inventor: COX ALFRED ANTHONY
IPC: A01F15/07
Filed: 1990-02-02
Abstract: The invention relates to bale wrapping machines of the kind used in agriculture to wrap large round bales of fodder with a plastics film. The machine has a turntable 1 which rotates about a vertical axis 18. The turntable supports a pair of rollers and an endless belt which carry, and rotate about a horizontal axis, the bale to be wrapped. The rollers are driven by a drive shaft 3 the shaft mounting a drive sprocket, which is rotatably-driven by engagement with an indexing rack 20 (Fig. 2) of rollers or pegs mounted on platform supporting the turntable. The invention is particularly concerned to prevent accidental contra-rotation of the drive shaft 3 and comprises a brake 30 which normally acts on the drive shaft 3 to prevent rotation of the drive shaft but is released to permit rotation of the drive shaft 3 when the rollers are driven i.e. when the shaft drive sprocket is engagement with the indexing rack or racks. The brake 30 is a disc brake 33 which acts on a disc 32 fixed to the drive shaft 3. The brake is released by a cam mechanism 40, 50 (Fig. 4). <IMAGE>

Title: Solenoid operated safety valve
Inventor: PERKINS DONALD HERBERT
IPC: E21B34/00
Filed: 1990-06-08
Abstract: A solenoid operated valve system for petroleum production wells includes a solenoid operated valve securable in a well bore connected to the lower end of a tubing string extending to the surface. The valve of the system includes an outer housing 442, an inner wall defining a flow passageway therethrough and an annular cavity therebetween for receiving the solenoid coil 415 and associated electrical components. The spaces in the annular cavity surrounding the solenoid coil 415 and components is filled with an electrically insulative filler material 408 to protect the electrical elements from borehole fluids. The solenoid operated valve has an operator tube 430 formed of tubular sections of different magnetic characteristics so that the valve is opened against a biasing spring by a high current flow and held open by a current flow of a lower value. The valve solenoid is operable by either AC or DC current. <IMAGE>

Title: Apparatus for powder falling gas-solid contacting operation
Inventor: WACHI SHUN
IPC: B01J8/18
Filed: 1990-08-07
Abstract: Powder is supplied from hopper 1 to fluidised bed 6 from which it is discharged at a steady rate through apertured plate 11 to a gas-solid countercurrent treatment tube 12. To assist in the maintenance of a steady rate of powder movement, the height of bed 6 is kept constant by surrounding the powder supplying standpipe 2 with vertical tube 3 extending below the end of the standpipe and into the bed so preventing fluidisation around the bottom of the 10 standpipe. Fluidising air is supplied through permeable base 8 and treatment gas through pipe 15. The gas is discharged via 6 conduit 10 into headspace 7 together with any solid entrained in the gas stream. Exemplified is the treatment of PVC particles with air. <IMAGE>
Patent GB-2249602-A (GB)
Title: Repairing pipelines and passageways
Inventor: WOOD ERIC
IPC: F16L55/164
Filed: 1990-08-15
Abstract: The invention provides that imperfections in the wall of a passageway or pipeline surface are repaired by wiping curable synthetic resin cement or mortar against the surface. The wiping is effected by forming a pool of resin between a first tubular member and the surface, and by everting a second tubular member into the first tubular member to wipe the pool of resin from one end of the passageway or pipeline to the other. The tubular members may be removed and may be formed or rubber or plastics. A camera pig may be used within cold water in the first tubular member to monitor progress. Hot water may be used to even the second member and cure the resin. <IMAGE>

Patent GB-2237780-A (GB)
Title: Height control of air-suspended vehicles
Inventor: GRIFFITHS PAUL JOHN
IPC: B60G17/052
Filed: 1990-10-31
Abstract: Air suspended vehicles, for example trailers, are frequently fitted with an air suspension system which selectively permits inflation/deflation of the suspension to level the load platform with a dock for loading/unloading. Damage can occur to the suspension and its shock absorbers it the suspension is not returned to normal ride height before, or on, leaving the dock. Selector 8 is operated to pass pressure air from supply 23 to the pilots of valves 65, 66 so isolating the height control valve(s). This enables inflation of the suspension via valves 111, 113 and pipes 38, 42, or deflation by operation of valves 112, 114, also via pipes 38, 42 and pipe 121. Service brake actuation energises solonoid valve 67 via cable 69 from the vehicle brake light circuit so that valve 8 is reverted by pressure air at its pilot, allowing valves 65, 66 to revert. The suspension is now restored to control by the height control valve(s) which effect restoration of the suspension to its normal ridge height. Alternatively, valve 8 may be reverted by direct application of brake line pressure. Each side of the suspension may be inflated/deflated independently. <IMAGE>

Title: Pipeline pig
Inventor: SIVACOE ORLANDE
IPC: B08B9/04
Filed: 1992-03-11
Abstract: A pipeline pig has hollow flared ends 16 and a central portion 14 of smaller radial dimension than adjacent parts of the pig. Detachable appendages 32 (eg. cleaning pins) extend radially outward from the pig in circumferential rows. At least one row of appendages 32 is in the central portion 14 and the appendages extend radially outward less than the other rows of appendages. The appendages are threaded into sleeves 34 (Fig 2) having anchored bases 36. The row of appendages that extends radially outward by a smaller amount than the other appendages is subjected to reduced wear, but when the pig encounters resistance, the central part of the pig extends outward bringing the appendages into contact with the interior of the pipeline. <IMAGE>
