Patent GB-2296886-A (GB)
Title: Pipe preparing tool
Inventor: SHELTON ANTHONY ROBERT
IPC: B26D3/16
Filed: 1995-01-12
Abstract: A pipe preparing tool comprises a frame 2 having an opening to receive a pipe. Tapered rollers 5 are mounted transversely on the frame; the first and second tapered rollers having opposed directions of taper. A cutting, scoring or penetrating means 14 is mounted on the frame and spaced apart from the first and second rollers. Clamping means apply a clamping force to the pipe such that the first and second tapered rollers engage the pipe and the cutting, scoring or penetrating means penetrates a surface layer of the pipe. When the pipe and the tool are rotated relatively to one another a helical groove is cut in at least a surface layer of the pipe.

Title: Apparatus for use in clearing land mines
Inventor: BOOTH ROBERT HENRY
IPC: F41H11/16
Filed: 1995-11-08
Abstract: Apparatus for clearing land mines comprises a plurality of rollers (40) carried on parallel arms by a common support frame (61 - 77) attachable to the front of a drive vehicle which can push the apparatus over the ground in front of it. The rollers are displaceable individually in a vertical direction on the support frame so that they all remain in rolling contact with the ground, exerting their weight thereon, despite variations in the ground surface, enabling the entire width of a band of ground in front of the vehicle to be swept. <IMAGE>

Patent GB-2313259-A (GB)
Title: Channel de-allocation in discontinuous transmission mode
Inventor: SHAHAF MARK
IPC: H04W76/04
Filed: 1996-05-17
Abstract: When a voice activity detector in a mobile senses a period of silence, the mobile enters a discontinuous transmission mode (DTX) in which it normally sends a "SPEECH-OFF" message or packet periodically to a base station. A DTX timer in the base station is started 64 or reset 67 on receiving a SPEECH-OFF message. If no such message is received for a period long enough for the DTX timer to time out 68, the base transmits a "SEND SPEECH" message 69. If the base does not receive speech 71 or a SPEECH-OFF message 73 within a certain time 70 following the SEND SPEECH message, it is assumed that the mobile is out of range and the base station will then de-allocate the channel in use 74, freeing it for use by another mobile. The channel may also be de-allocated if the mobile has been in the discontinuous mode for greater than a threshold time. The base may transmit a message warning that channel de-allocation is to occur, and the mobile may then send speech or some other message indicating that the channel should not be de-allocated.

Title: A latching system
Inventor: WILLAMS ADRIAN PAUL
IPC: E21B33/035
Filed: 1996-11-01
Abstract: A latching system for releasably securing a subsea control module 2 to a mounting base 8 comprises at least one spigot 26 on one of the module 2 or the mounting base 8, a fixed inner mounting collar 18 on the other, and an outer locking ring 20.

Inventor: ROBISON DAVE
IPC: F16L25/12
Filed: 1997-01-03
Abstract: The assembly comprises a elongate sleeve 18, receiving coaxially the two opposing pipe ends 12, 14, having frusto-conical ends 20 opening outwardly and slidably receiving a pair of annular elastomeric gaskets 22 which fit into the frusto-conical ends; a separate retaining ring 40 is located axially outward of each sleeve end and has a frusto-conical inner wall 44 facing the sleeve to define a gripping ring chamber containing a split, radially compressible gripping ring 40 and an engagement ring 24 located between the elastomeric gasket 22 and the gripping ring at that respective end. Tie rod members are provided selectively to move the retaining rings 40 axially toward one another to compress the gaskets 22 into their respective frusto-conical chambers of the sleeve and radially to compress the respective gripping rings 30. Cooperating stop surfaces on the sleeve 18 and retaining rings 40 limit movement toward one another to provide positive limit to the compression applied to the gaskets and the gripping rings. The engagement rings 24 also have movement limiting abutment surfaces cooperating with the sleeve ends and retaining ring shoulders. The gripping rings 30 may have metal inserts.

Title: Torque transmission arrangement
Inventor: OTTO DIETER
IPC: F16H61/00
Filed: 1993-08-21
Abstract: A torque transmission arrangement for the drive transmission train of a vehicle which has a gear change gearbox. The arrangement comprises a hydrodynamic torque converter 11 connected to the vehicle motor and also connected by way of an output shaft 14 to an inline automatic gearbox on the output side of the system. A friction clutch 12 is arranged parallel to the torque converter 11. The clutch is fluid pressure operated and has, on the one hand, a pressure chamber 24 between a turbine wheel 18 of the converter and an annular piston 74 operably connected to a friction plate 78 and, on the other hand, a pressure chamber 25 arranged between the annular piston 74 and a converter cover 70. The chambers 24,25 are designed such that a differential pressure present between these pressure chambers determines the torque transmittable by the friction clutch. The arrangement also has a hydraulic system which transmits an intended change to the differential pressure between the two pressure chambers and thus determines the torque transmissible by the clutch. The clutch is controlled such that it is partially engaged, at least some of the time, in all forward gears.

Title: Plain bearing
Inventor: MCMEEKIN KENNETH MACLEOD
IPC: F16C33/04
Filed: 1997-01-29
Abstract: A plain bearing comprises a metal backing, a layer of a porous matrix of sintered metal on the backing and a filled PTFE infiltrated into the interstices of the sintered layer and standing proud of the sintered layer, wherein the PTFE is filled with 1-20% by volume fibrillated aramid fibres and 10-30% by volume glass. The glass is preferably E-glass present as milled filaments of length 0.05 - 0.30 mm and diameter 0.010-0.020 mm and coated with a silene sizing agent. The fibrillated aramid fibres provide reinforcement and improved load bearing capacity and the glass provides an abrasive filler which abrades asperities on a body and creates a smooth polished surface against which to bear, thereby improving its life. The PTFE preferably also includes ferric oxide and carbon black to about 1.5% and 1.2% by volume respectively which both pigment the polymer and act as fine abrasive and lubricant respectively. The carbon black content may be increased to about 10% to provide electrical conductivity. The filler may be prepared as a wet mush or a dry 'paper'.
