Title: Improved tensioning apparatus for overhead electric traction systems
Inventor: JANANI FARHAD
IPC: B60M1/26
Filed: 1989-06-22
Abstract: In tensioning apparatus for overhead electric traction systems in which the risk of shock loads on the tensioning apparatus and/or on a conductor of the system arising from breakage of the conductor is reduced, the pulley assembly of the apparatus includes a stop 17 which is pivotably mounted with respect to the mast at a position below a toothed wheel 3 coaxial with the pulley 4 of the assembly and which has a plurality of teeth 18 so shaped and mutually spaced that teeth of the stop can inter-engage sequentially with teeth 15 of the wheel. In the event of breakage of the conductor and rotation of the pulley assembly caused by falling balance weights, the pulley assembly pivots downwardly with respect to the mast so that teeth 18 of the toothed wheel coaxial with the pulley inter-engage sequentially to cause rotation of the pulley to be gradually and smoothly arrested. <IMAGE>

Title: Determining the background radiation level in the region of a characteristic Raman peak
Inventor: MILLS CHRISTOPHER BRUCE
IPC: G01J3/28
Filed: 1990-01-19
Abstract: In order to determine the level of background radiation (54) in a spectral region of a Raman peak (10) characteristic of a particular substance e.g. diamond, the radiation is measured in a first spectral band (24) and in a second spectral band (26) which overlaps the first to form an overlapping band (76) in the vicinity of the Raman peak and also sidebands (30 and 32). Values (42 and 46) representative of the radiation in the sidebands are then obtained and used to derive a value (54) indicative of the background level at the position of the Raman peak (10). Further values (34 and 36) representative of the radiation in other spectral bands, such as the first and second bands (24 and 26), may also be used in the deviation of a background value (52) by means of curve fitting techniques. Alternatively the average background level of two side bands may be obtained by subtracting the central band (16) measurement from a measurement of a single band spanning both side bands and the central band. <IMAGE>

Title: Borehole packer
Inventor: TOON DONALD ARTHUR
IPC: E21B33/127
Filed: 1990-09-27
Abstract: The packer (4) is for use in isolating long lengths of a borehole (2), eg between sampling points. The packer includes bentonite (23) which is activated by the natural groundwater in the borehole. The water is admitted into the bentonite through narrow portholes (20), which delay the flow of water into the packer. The water is distributed evenly throughout the bentonite by means of blotting paper (14, 16), which soaks up the incoming water and prevents the water passing to the bentonite until the blotting paper is all saturated. Alternatives to the use of blotting paper, to transmit the water evenly over and through the whole body of bentonite, include perforated corrugated plastic, corrugated cardboard, and perforated plastic pipes. <IMAGE>

Patent GB-2254916-A (GB)
Title: Detection systems
Inventor: TRETT JOHN
IPC: G01V8/12
Filed: 1991-04-15
Abstract: A detection system includes an infrared emitter (2) and an infrared detector (8) having optical axes (6) and (12) extending parallel to one another but being offset from one another. As the detector (8) and the emitter (2) approach one another the distance between them decreases but their angular separation increases. Accordingly, the increase in signal engendered in the detector as it approaches the emitter is countered to some extent by the greater angular separation. Accordingly, the net result is that any change in output of the detector resulting from a change in its spacing from the emitter is substantially reduced.

Patent GB-2256715-A (GB)
Title: Method for drilling directional wells
Inventor: WU JIAN-GUN
IPC: E21B47/022
Filed: 1992-06-12
Abstract: A method for detecting and sensing boundaries between strata in a formation during substantially horizontal directional drilling so that the drilling operation can be adjusted to maintain the drillstring within a selected stratum. The method comprises the initial drilling of an offset well from which resistivity of the formation with depth is determined. This resistivity information is then modelled to provide a modelled log indicative of the response of a resistivity tool within a selected stratum in a substantially horizontal direction. A horizontal well is thereafter drilled wherein resistivity, measured by electromagnetic propagation, is logged in real time and compared to that of the modelled horizontal resistivity to determine the location of the drillstring and thereby the bore hole in the substantially horizontal stratum. From this, the direction of drilling can be corrected or adjusted so that the borehole is maintained within the desired stratum. In another embodiment, a modelled log is created to match the measured log and the parameters from the model are used to determine and control the location of the drill. <IMAGE>

Abstract: Aligned holes in flanges 112 and 111 are occupied by neighbouring studs (or bolts), a hydraulic nut 40 being screwed onto one of the studs, and a nut 15 and a hydraulic tensioner 50 being screwed onto the other stud, so that hydraulic pressure supplied to the hydraulic nut 40 urges the flanges 112 and Iii together, and hydraulic pressure applied to the hydraulic tensioner 50 develops a predetermined tension in the other stud which can be maintained by rotating the nut 15 into engagement with the flange 112. A transducer 72 senses the actual residual stress, and a correction may be applied by restressing and rotating the nut 15 by a computed amount. A number of bolts may be installed simultaneously. <IMAGE>
Patent GB-2268581-A (GB)
Title: Optical fibre diffraction grating sensor
Inventor: JACKSON DAVID ALFRED
IPC: G01K5/52
Filed: 1992-07-03
Abstract: Fibre diffraction gratings SG1-SG4 working in different bands reflect narrow bands of the incident broadband radiation 10. The reflected light wavelength depends on the grating pitch, allowing strain or temperature to be detected. The pitch of receiver gratings RG1-RG4 is modulated by e.g. a PZT device so that pulses are detected by photodiodes D1-D4 when the respective grating pitches match. Time of occurrence of the detected pulses with respect to the modulation conveys the sensed parameters. Multiple fibres may be accommodated by pulsing the source and using fibre delay lines. <IMAGE>

Filed: 1991-10-17
Abstract: A battery housing base (300) with an integral, sliding channel mechanism (507) for attaching a battery to portable electronic equipment (102) is disclosed. The slide-on battery (105) is captivated by limited travel guide rails (307 through 312) within the sliding channels (507) along each opposite edge of the mating surface (302) of the battery housing base (300). Indentations (313 through 316) are disposed between neighboring limited travel guide rails (307 through 312). The indentations (313 through 316) enable the limited travel guide rails (307 through 312) to be manufactured using a single shot injection, straight pull ejection molding process and to be easily attached to the portable electronic equipment (102). The single shot injection mold process controls all critical interface dimensions on the battery housing base (300) for proper attachment to the portable electronic equipment (102). The critical interface dimensions are disassociated from the attachment of a battery housing base (300) to the battery housing cover (202).
Patent GB-2271894-A (GB)
Title: Electric appliance
Inventor: RICHARDS DAVID ALEXANDER
IPC: H02H3/33
Filed: 1992-11-03
Abstract: When a carriage of a toaster is in a lower position, a switch (21) is closed and power passes through a bridge rectifier circuit (22) to an integrated circuit (19), which, for the normal toasting operation, switches SCR (20) off so that a relay (7) is energised, closing switches (8) and (9) to energise heating elements (2) and (3). Power is also supplied to a latch (27) to hold the carriage in the lower position. If, however, a fault detection is input from a residual core balance (12) to the integrated circuit (19), SCR (20) is switched on so that power from bridge rectifier (22) is shorted. This causes relay (7) and latch (27) to be de-energised so that the heating elements (2) and (3) are turned off and the carriage is returned to the upper position, causing switch (21) to open. A potentiometer (28) sets toasting time. Intergrated circuit (19) may include an oscillator and counter which compensate toasting time if the heating elements are still hot from a previous operation. <IMAGE>
