Patent GB-2267932-A (GB)
Title: Friction stay with spacer
Inventor: LANAWAY RONALD PHILIP
IPC: E05D15/44
Filed: 1992-06-16
Abstract: In a friction stay for windows of the type having an open topped track which is fixed on the window frame and which pivotally mounts a link arrangement attached to the window, a closure member 30 for one end of the track has a support section 32 mounted within the track and upstanding sections 36, 38. A spacer 54 has a mounting part 56 adapted to snap fit on the mounting section 38 and a shroud part 60 to overlie the profiled section 36. The spacer 54 can have a selected dimension between its front and rear spaces to occupy whatever space is present when the track is mounted at a suitable location on the window frame. The closure member 30 and the spacer 54 can be fixed to the adjacent window frame part. Security of the window is improved because the spacer 54 limits unauthorised access to the closure member 30 and the mounting of the latter makes it more difficult for unauthorised displacement from the track. <IMAGE>

Title: A battery charger for nickel-cadmium cells
Inventor: BARKER PETER F
IPC: H02J7/00
Filed: 1992-06-18
Abstract: The charger has an access lid 11 hinged at 12 and provided with a seal 13 so that on closure of the lid 11 a cell- receiving housing is sealed to contain any gas vented from the cells on overcharging. A differential pressure sensor, sensing the pressure differential between the housing and the ambient atmosphere, is responsive to such venting to terminate charging. Alternatively, or additionally, charging may be terminated by a pyroelectric transducer which detects thermal radiation from a cell being charged. Charging may be inhibited by a switch 17 unless the lid 11 is closed. In order to avoid operation with an impaired seal 13, charging may be enabled only when a small threshold over-pressure (generated by other means) exists in the cell- receiving housing. <IMAGE>
Patent GB-2258180-A (GB)
Title: Adjustable wrench.
Inventor: FRANKLIN MICHAEL JOHN
IPC: B25B7/12
Filed: 1992-07-27
Abstract: An adjustable wrench has laws 1, 2 which automatically lock up when a predetermined force is applied to handgrips 3, 6. The jaws are closed by forcing together the hand grips which holds pivot F against rubber stop 8 mounted in a housing 9, which in turn is mounted on brace arm 7; pivot D is moved towards brace 7, thus straightening line CDE and rotating jaw 2 and pivot C anti-clockwise about pivot B. When the jaws close on to a workpiece W, further movement of D towards arm 7 is arrested in favour of the over-centre linkage arms 4 and 5 whereupon eccentric cam 11 locks rod 10 against anvil 12 thus holding jaw 2. The over-centre lock on the hand grip 6 locks and is prevented from going further than just over-centre by a stop which bears on to the inside of the hand grip. A wrench with sliding jaws is also disclosed (Fig. 5, not shown). <IMAGE>

Title: Electro-optic modulators and optical frequency convertors in glass waveguides
Inventor: RUSSELL PHILIP STJOHN
IPC: C03C23/00
Filed: 1993-06-17
Abstract: Second order non-linearities in glass are created by exposing glass to an electron on beam. Electrons from the beam penetrate the glass to set up a space charge field to give rise to a second order non-linearity. As electron beams, in particular, can be readily and accurately controlled, the location and size of non-linearities can accurately be determined. The beam may also be used to modify, for example, to erase, non-linearities formed by conventional poling methods.

Title: Direction finding
Inventor: KRONHAMN THOMAS ROLF
IPC: G01S3/14
Filed: 1994-11-17
Abstract: A method for determination of the direction to a signal source by cooperation between a first device which determines the direction to the signal source with a low angular accuracy and a second device which determines the direction to the signal source with a high angular accuracy. In a first step (1), the direction to the signal source is determined within a certain angular range and, through analysis of the signal transmitted from the signal source, the category of the signal source is determined. In a subsequent second step (2), an angular search for a signal source of said category is performed within said angular range, in which the search is interrupted in the direction in which a signal of said category is detected. In a subsequent third step (4), the detected signals are correlated with respect to time. When correlation is present, the direction to the signal source is determined by determination of the direction in which the signal source is detected. When correlation is not present, the search is continued until a new signal source of said category is detected, at which the search is again interrupted and said third step is repeated. <IMAGE>

Title: Pipe towing Device
Inventor: BRYANT STUART
IPC: F16L55/18
Filed: 1997-03-06
Abstract: The towing device comprises a static conical forward section 3 and moving gripper rear section linked such that relative horizontal displacement caused by rotation of a central screwed rod 6 coupled to a towing eye 1 causes radial movement of serrated gripper segments 7 which affix to the inner surface of the pipe. An additional applied horizontal force, as when towing against the dead-weight of the pipe, results in an increased gripping force by movement of a nut 9 against a compression spring 8 between it and a fixed tube 5 and plate 4 structure. Partial retraction of the grippers 7 occurs when the towing force is removed, aiding quick release of the device. The device is particularly suitable for use when installing polymer pipes in straight or coiled lengths as used in the gas and water industries.
