Title: Bandwidth compression of a colour television signal
Inventor: DAY SIMON WILLIAM
IPC: H04N11/02
Filed: 1997-10-31
Abstract: The luminance and chroma components of a television signal are separated and the luminance filtered to reduce its bandwidth, 2a, to below the chroma component 4a. One of the components is shifted to reduce the separation, in particular the luminance 2b is shifted to be above the chroma band 4b. The two components are recombined and modulated on an rf carrier, the frequency preferably being increased in a plurality of steps. The compressed signal is restored by separating the luminance and chroma and restoring the shifted component. The compressed signal may be transmitted in a 10MHz channel and is particularly suited to surveillance systems.

Title: Vehicle tracking systems
Inventor: GRANT QUENTIN SHOLTO
IPC: B61B13/04
Filed: 1997-12-05
Abstract: A vehicle tracking system comprises a plurality of vehicles 1 driven on tracks defined by upper and lower track members 2a, 2b by drive units 8a - 8f each comprising two drive wheels and two locating wheels which are driven by respective drive motors 4a - 4f. The drive units are powered by electricity which is supplied from a conductor positioned on the track members 2a, 2b. Each drive unit is arranged to move between a position where it engages the track member and a position removed from the track member, in which position it can move laterally in relation to the track member so as subsequently to re-engage a track member, e.g. 2e, of an adjacent track. Disengagement and subsequent re-engagement are effected by means of ram mechanisms 12a - 12f, three of which 12b, 12d and 12f are arranged to move laterally using slide mechanisms 13a, 13b and 13c. At bends in the track, the upper and lower track members 2a, 2b are positioned off-centre so as to provide banking of the vehicle.

Title: Friction clutch
Inventor: SCHULZ-ANDRES HEIKO
IPC: F16D13/71
Filed: 1995-07-12
Abstract: A friction clutch has a flywheel 1 and a clutch housing 7 connected through a cylindrical wall 5 extending in the radially outer region of the clutch housing 7 and enclosing a clutch plate (10) with friction linings 28 and a pressure plate (18) urged in the direction towards the clutch plate (10) by an actuating spring 15. The outer periphery of the friction linings 28 is arranged directly adjacent the cylindrical wall 5. The ratio of the outside diameter to the inside diameter of the friction linings is less than 1.4. The friction linings 28 are connected to clutch plate (10) by a lining spring arrangement 55 the maximum axial deformation of which is limited to an amount sufficient to compensate for thermal distortions particularly of the pressure plate 12 but also of the flywheel. Further resiliency in the direction of displacement of the pressure plate is provided by the nature of the construction of the clutch housing 7 with at least one resiliently deformable region.
Patent GB-2326021-A (GB)
Title: Field oxide fabrication
Inventor: JANG SE AUG
IPC: H01L21/76
Filed: 1998-04-24
Abstract: A pad oxide insulator 13 is constructed on a semiconductor substrate. An over-etching process is performed to recess the semiconductor substrate to a predetermined depth while giving a pad insulator pattern. After an insulating nitride spacer 17 is formed at the side wall of the pad insulator pattern, the exposed region of the semiconductor substrate is thermally oxidized to grow a sacrificial oxide 19 which is, then, removed to form a recess. An element isolation film is formed in the recess by break-through field oxidation and high temperature field oxidation. The element isolation film thus obtained can prevent the field oxide "ungrowth" phenomenon and at the same time mitigate the field oxide thinning effect as well as improve the properties of the gate oxide.

Title: Golf club with insert in head providing golfer with more 'feel'
Inventor: BUCHANAN DOUGLAS BOYD
IPC: A63B53/04
Filed: 1998-06-17
Abstract: A golf club such as a putter 10 comprises a head 11 connected to a shaft 12. The head 11 comprises an outer shell 15 defining a cavity 16 in which is received an insert 17. The insert 17 is arranged so that the sweet spot on the head 11 is at the centre of the circular face of the insert 17. The shaft 12 extends through the shell of the club head and is connected to the insert 17. The connection may be by means of a hosel member 13 fitted to the insert 17. The insert 17 may be made of a soft, ductile material such as bronze which facilitates the transmission of shock. As the shaft 12 is connected directly to the insert 17 and the insert 17 is spaced from the shell 15 and isolated from it by, for example, resilient O-rings 22, 25, any energy which is generated by hitting a golf ball is transmitted up the shaft without being dissipated in the club head. This provides the golfer with a greater 'feel' for the shot. A void 21 is left behind the insert and it has been found that the presence of this enhances the feel factor.

Title: Stop tap
Inventor: SPENCE ROBERT EDWARD
IPC: F16L55/10
Filed: 1998-09-09

Title: Motor vehicle suspension system
Inventor: BROOKES GRAHAM ROBERT
IPC: B60G17/0195
Filed: 1997-05-21
Abstract: A motor vehicle suspension system includes rear suspension units (21, 22) to adjust ride height between sprung and unsprung parts of the vehicle, control means for monitoring and maintaining ride height at a particular setting and wheel speed monitoring means for monitoring wheel speeds. The control means (31) provides a corrective up height change signal (47 or 48) in the event of an unrequested height change (41) and there existed before the unrequested height change a wheel speed signal (44) indicative of vehicle movement. The corrective height change signal (48) may be applied to each suspension unit or the control means may monitor abnormal vehicle activity and provide the corrective height change signal (47) to the appropriate suspension unit. One example of abnormal vehicle activity is when the wheel speeds differ significantly, the control means responding to provide the corrective height change signal to the suspension unit on the side of the vehicle with the highest wheel speed. A second example of abnormal vehicle activity is where the suspension unit uses fluid pressure to support the vehicle and a difference in pressures before and after the unrequested height change is used to provide the corrective height change signal to the suspension unit on the side of the vehicle with the lowest suspension pressure.

The coupling is further provided with a sealing ring 7 which may be made from polytetrafluoroethylene and is compressed between the end face of the male member and sits in an annular groove 6 of the female member. The length LF of the parallel thread 5 is derived from a formula involving the gauge diameter, the thickness of the sealing ring 7, the desired reduction in depth of seal on compression and the thread size designation fraction. The coupling is preferably manufactured to British Standard BS21:1985.

Title: Process for reducing water flow into a hydrocarbon production well
Inventor: MUNDAY KEITH
IPC: C09K8/508
Filed: 1998-11-12
Abstract: A process for preventing water ingress into a hydrocarbon production well (4) firstly involves injecting a permeability modifier (14) into the hydrocarbon and water producing zones (6 and 8 respectively). Secondly a flow blocking composition (16) is introduced into both zones. The well is then shut in for a period long enough to allow for the reaction of the permeability modifier. Both the permeability modifier and the flow blocking composition are subsequently removed from the hydrocarbon producing zone only. This allows the production of hydrocarbons from this zone whilst the flow blocking composition forms a water shut-off in the water producing zone.

Title: An arrangement for biasing the gate of a transistor in the low noise amplifier of a receiver to protect the transistor from an excessive input
Inventor: KIRISAWA AKIHIRO
IPC: H03F3/72
Filed: 1999-03-18
Abstract: A circuit for controlling a low-noise amplifier having a low-noise transistor as an amplifying device, includes a bias voltage controller (5) (fig 1) decreasing a voltage to be applied to a gate of the transistor down to a voltage equal to or smaller than a pinch-off voltage to thereby pinch-off the low-noise amplifier (3), while power to be provided to the low-noise amplifier (3) is inhibited. Even if an excessive input signal is input into the low-noise amplifier while the low-noise amplifier is not in operation, gate current does not flow through the transistor constituting the low-noise amplifier. Hence, it is possible to minimise the likelihood that the device will be destroyed.
