Patent GB-2241902-A (GB)
Title: Excercise machine
Inventor: VAN STRAATEN WILLEM JOHANNES
IPC: A63B23/00
Filed: 1991-03-05
Abstract: An exercising machine comprises a stand carrying a pair of seat members 13 hinged to the stand at adjacent edges. The seat members may be pivoted from the horizontal to the vertical. Elastic bands 23 are looped around pulleys (17, 19), 21 on frame. The looping is such that the bands double back on themselves at least once, thereby reducing the space required for operation of the machine. Handles may be engaged with any one or more of the bands to be gripped by the hands or ankles. By changing the inclination of the seats and the choice of elastic bands a large variety of exercises may be performed in sitting or prone positions. <IMAGE>

Title: Turbine blade repair
Inventor: FRASER MICHAEL JAMES
IPC: B23P6/00
Filed: 1991-06-05
Abstract: A method of repairing stator blades 12, 13, 14 in a turbine 10 comprises the steps of making a pre-shaped insert 28, 29, 30 of a material the same as or compatible with the material of the stator blade, the insert forming a substantial part of the stator blade, removing a piece of material from the stator blade including the damaged part, and welding in the new insert. The insert is treated so that at least a part of it is hardened. The hardening may be diffusion alloying or plasma spray and the weld line between the insert and the turbine blade is removed from the area of high wear by making the insert larger than would apparently appear necessary. This allows better access to the stator blades for securing the new insert and/or for additional hardening steps after the insert has been secured to the stator blade. <IMAGE>

Patent GB-2281486-A (GB)
Title: Sample pulse generator for automatic kinescope bias system
Inventor: FLICKNER ANDREW KENT
IPC: H04N5/68
Filed: 1994-08-26
Abstract: Control circuitry 60, in an AKB sample pulse generator, enables charging of a capacitor 82 upon initiation of a vertical retrace pulse S6, initiates discharge of the capacitor in response to termination of the retrace pulse and concurrently produces an AKB output pulse (SP) having a width (W) determined by an RC time constant and having a delay time (Td) relative to initiation of the retrace pulse that is equal to the length (L) of the retrace pulse and that is independent of the value of the RC time constant. Thus the AKB sample pulse delay time tracks variations, if any, of the retrace pulse and is unaffected by parameter variations of the RC components. The sample pulse width can be controlled with increased "aperture" or sampling time. Independence of the delay time (Td) from the RC time constant is ensured by arranging for the RC time constant to be shorter than the duration of the vertical retrace pulse. <IMAGE>

Title: Reducing the light-off time of a catalytic converter
Inventor: MA THOMAS TSOI-HEI
IPC: F01N3/20
Filed: 1996-01-13
Abstract: An internal combustion engine is disclosed having a catalytic converter and an exhaust gas ignition (EGI) system for assisting in reducing the light off time of the catalytic converter. The EGI system comprises means for enriching the mixture in the engine combustible charge during cold starts in order to produce exhaust gases containing sufficient hydrogen and carbon monoxide to be ignitable when cold upon the addition of air to the exhaust gas mixture, and means for igniting the mixture upstream of the catalytic converter to generate a flame for heating the catalytic converter. To increase the hydrogen content in the exhaust gases for any given mixture strength supplied to the engine combustion chambers, the invention teaches advancing the spark timing of the engine, or retarding the opening of the engine exhaust valves, during operation of the EGI system to achieve a lower burnt gas temperature prior to the opening of the exhaust valves.

Inventor: TYRER ANDREW CHARLES RATCLIFFE
IPC: F16L11/18
Filed: 1996-10-14
Abstract: A cable spacer assembly for use with underwater oil or gas pipelines, is formed from interconnected hollow cable spacer elements (10 Figures 1 and 2) having apertures 40 to allow ingress of water. Each element (10) is formed from two conjoined, semicylindrical halves 10' (Figures 3 to 5), the halves being held together by titanium bands 46, 48 in grooves 42, 44. One element (10) connects to an adjacent element by means of an internal socket 18 which is adapted to receive the flange 16 of an identical adjacent element. The inter-engagement of the socket 18 and flange 16 permits longitudinal and/or annular play of spacers which enables the assembly as a whole to flex. The neck 24 corresponds closely to the outside diameter of the cable to be positioned within the assembly and centres the cable. A clamp (50 Figure 2) may be secured to the cable in the recess 26 to prevent the assembly moving longitudinally along the cable.

Title: Access valve devices, their use in separation apparatus, and corresponding methods
Inventor: DAVIS JOHN
IPC: F16K1/44
Filed: 1995-10-03
Abstract: An access valve suitable for controlling fluid flow into and out of a chromatography column has a central axially movable probe with a head (71) acting as a spool valve in a barrel (6). Axial movement of the probe adjusts the valve between a fully open condition, in which both a first conduit (73) extending through the probe and a second conduit (51) defined around the probe are open to the column interior, a partly open condition in which a second sealing land (76) on the probe closes the second conduit (51), and a fully closed position in which both conduits are closed. The three positions are useful for packing and unpacking chromatography media into and from the column. In the closed condition of the valve, the first and second conduits (73, 51) communicate with one another so that the valve interior can be cleaned while the column is operating.

Title: Automatic gain control in direct sequence spread spectrum communication receiver
Inventor: KIM SUNG-SOO
IPC: H03G3/20
Filed: 1997-09-30
Abstract: A receiver for use in a direct sequence spread spectrum communication system is described. An RF amplifier 26 receives a signal from an antenna 20, a local oscillator 30 generates a local oscillation signal and a mixer 32 mixes the output of the RF amplifier 26 with the local oscillation signal to produce an intermediate frequency signal which is supplied to a base band stage 34 of the receiver. A received signal gain controller 40 controls the supply of power to the RF amplifier 26 to cause it to function as an attenuator during a packet reception interval when the received signal has a level higher than a predetermined operating level. The received signal gain controller also varies the level of the local oscillation signal in dependence upon the level of the received signal, when the received signal has a level which is equal to or lower than the said predetermined operating level, to match the output level of the mixer 32 with a predetermined input level of the base band stage 34.
