Patent GB-2292254-A (GB)
Title: Method for polishing semiconductor substrate
Inventor: NAKAJIMA TSUTOMU
IPC: B24B37/30
Filed: 1995-08-03
Abstract: Initially a valve 19 is set to connect a vacuum pump 17 to the rear surface of a substrate 1 to vacuum chuck the substrate on to a holder 2. Simultaneously with the pressing of the substrate on to a polishing cloth 9, the valve 19 is changed over to supply pure water from a reservoir 20 to form a liquid layer 12. The flowing liquid layer between the substrate and the holder supports the substrate therebetween by surface tension. The method ensures that a substrate is not damaged at a reverse surface thereof and also that a substrate is not contaminated by particles contained in a polishing liquid, because the flowing liquid layer prevents particles of polishing liquid from entering between the substrate and the substrate holder. <IMAGE>

Title: A liner for a well
Inventor: DIXON ROGER ALLAN
IPC: F16L21/08
Filed: 1996-07-03
Abstract: The liner (1) avoids collapse due to settlement loads by having tubular lining sections insertable one (2) inside another (3) with coupling means such as barbs or a spring ring (28) for inhibiting separation during installation, and limiting means such as shear-off pins or a welded ring (60) for limiting initial insertion, such being overcome in response to significant longitudinal settlement loads applied to the liner and thus allow further insertion. The spring ring (28) seats in a deeper groove (27) of the section (2) during insertion but upon reverse movement moves onto a shallower groove (25) such that it abuts a shoulder of a groove (36) in the section (3).

Title: Radar systems
Inventor: TAIT PETER DONALD FRASER
IPC: G01S13/18
Filed: 1996-09-27
Abstract: A coherent radar detection system (2) comprises a radar signal transmitter (4) and a correlation receiver (6). The transmitter (4) comprises a waveform generator which generates a signal at an intermediate frequency. The signal is divided into two divided signals by a coupler, (22) and then the divided signals are mixed together in a mixer (28) to generate an output signal which has a wider bandwidth than the intermediate frequency. The bandwidth can be increased further by repeating the coupler/mixer stage. The sytem generates very wide bandwidth signals coherently, allowing coherent processing in high resolution range gates.
Patent GB-968013-A (GB)
Abstract: 968,013. Fluid-pressure servomotor systems. BENDIX CORPORATION. June 12, 1962 [June 20, 1961], No. 22532/62. Heading G3P. A spool valve 56, Fig. 4, controlling a motor 72, 73 is moved by the pressure difference across the ends of the spool in response to an electrical signal which causes rotation of a baffle plate 40 to vary the leakage from nozzles 43, 44. The electric motor, which is hydraulically sealed from the valve portion, comprises an armature 23 mounted for rotation on a supporting arm 24 which is fixed to a torque tube 31, such as beryllium copper, secured at its lower end to the housing. A central shaft member 34, secured at its upper end to the torque tube, carries the baffle plate 40. The shaft 34 has a reduced diameter portion 50 at its lower end constituting a torsion spring which is secured to a rigid hollow shaft 51. The shaft 51 carries an arm 53 at its upper end engaging the spool valve 56. In operation, rotation of the armature causes twisting of the torque tube 31 and rotation of the shaft 34 to rotate the baffle plate to actuate the spool valve. As the spool valve moves, the lever 53 rotates the rigid shaft 51 to twist the torsion spring 50 and hence the shaft 34 to restore the baffle plate to its neutral position. The armature and baffle plate are mounted with their centres of gravity offset from the shaft axis whereby they will rotate in response to acceleration of the device to prevent movements of the spool. The shaft 34 may be actuated manually. Specifications 816,773, 816,774 and 816,775 are referred to.

Abstract: A stationary chuck comprises top jaws 21 each carried by base jaw 7 which in turn is carried on a chuck body 2 which sits on the chuck base 3. In the base 3 is a gearing system comprising a pinion 13 which meshes with a cam gear 6. The cam gear 6 carries slots that accept load pins 4 which are fixed to and carried by the base jaws 7. The load pins 4 mate with recesses in the under surface of the top jaws 21. The pinion 13 has a recess in its upper surface for receiving a turn key to turn the pinion and activate the gearing system. To close the chuck, a turn key is inserted into the pinion 13 and the pinion is rotated. Meshing cam gear 6 is caused to rotate simultaneously. As the cam gear rotates, the load pin travels in the slot 31 between the radially outermost portion of the slot and the radially innermost portion of the slot. The load pin 4 which is constrained from moving in an arcuate motion is forced to travel radially inward of the front plate 1 of the chuck carrying with it the top jaw 21. The chuck provides a compact, efficient and effective alternative to conventional scroll operated chucks.
