Patent GB-2332122-A (GB)
Title: Transmitting a downlink signal in different directions at different times
Inventor: VILLIER ERIC
IPC: H04B7/06
Filed: 1997-12-05
Abstract: In a communication system having two units 10, 12 the directions of selected signals from a plurality of muitipath uplink signals from unit 12 (P1, P2, P3 figure 1) are determined to be the directions p1, p2, p3 of transmission of the downlink signal from the unit 10. The downlink signal is transmitted in different directions in different time intervals thus reducing cross-cell interference and introducing diversity gain in the reception at unit 12. The communication unit 10 has an antenna (e.g. adaptive antenna, an antenna array or steerable beam) able to partition the receiving/transmitting area into a plurality of sectors S1 -SK and processing of the multipath uplink transmission from unit 12 determines principal signals P1-PM and the sectors S1-SM in which they are received. The principal signals can be for example, signals exceeding a predetermined power level or a set number (M) of the strongest signals. The downlink signals can be transmitted one sector at a time in a random or predetermined sequence and preferably the period of transmission in a sector is inversely proportional to the number of transmission signals or sectors SM. The transmission time could also be related to the transmission power, with lower power transmissions having longer duration. The transmission power for each sector may be inversely proportional to the power of the signal received in that sector.

Title: Non-linear saser
Inventor: CAHILL MARK DAVID
IPC: G10K15/04
Filed: 1998-06-16
Abstract: A sound wave of a particular frequency and travelling in a particular direction is amplified by causing it to interact with a high-amplitude standing wave of the same frequency, but oscillating in a different direction to the sound wave. The standing wave (pump mode) is set up in a suitable medium, e.g. a liquid alcohol such as ethanol, between acoustic mirrors 1.

Title: The detection of airborne pollutants
Inventor: KNOX RONALD
IPC: G08B17/107
Filed: 1997-05-02
Abstract: A smoke detection system comprises a manifold (4) connected to a series of sampling pipes (2). A fan (6) which draws a large volume of sampling air through the sampling pipes is connected to the inlet manifold and a small proportion of that air is directed to the inlet of a smoke detector (12), the outlet of which is connected to the manifold. The configuration obtained by the connection of the outlet from the detector into the inlet manifold provides a large pressure drop across the flow path through the detector. As a result of the large pressure drop, a filter (10) for removing dust and other contaminants can be incorporated in the flow path and the filter can also incorporate a fine filtering stage to produce a secondary clear air flow which can be directed into the detector to prevent smoke particles from settling on critical components of the detector.

Title: Solar cell array orientation by airship roll
Inventor: HILLSDON REGINALD HAROLD
IPC: B64B1/24
Filed: 1999-02-09
Abstract: An airship has an array of solar cells 3 having a centre of gravity 21, the cells being fixedly mounted to the hull (2, fig 1), and extending around a portion of the circumference of the hull. A payload is arranged in a gondola 5. Cables 8 & 10 are attached to the hull at points 15,16 and 18,19 respectively, cables 7 & 9 having pulleys 14,17. The gondola 5 has winches for changing the length of cables 6,7 & 9, moving the weight of the gondola 5 to roll the airship so that the solar cells 3 can track incident light from the sun.

To ensure that the power module is space saving whilst maintaining satisfactory heat dissipation and to simplify the electrical connection between the power module and the remaining components of the frequency converter, the only electrical connection between the power module 2 and other electrical components of the current converter as well as to the supply mains and to a load, such as a motor, supplied via the converter is made by way of the connecting parts 27, 28.
Patent GB-2335180-A (GB)
Title: Device for grasping articles
Inventor: BOARD MARK LYDON
IPC: B66C1/42
Filed: 1999-04-09
Abstract: A device for grasping an article, eg a pipe, comprises two pivotally attached limbs 1, 2, an end of a first limb being pivotally attached to an intermediate part of the second limb at a pivot point, where a pin 10 may be located. An abutment 15 is arranged at the end of the first limb opposite from its pivot point, and a pair of abutments 14, 16, are arranged at respective opposite ends of the second limb, with the pivot point arranged in between. The abutments abut the article when grasped, with an inner one of the abutments on the second limb generally intermediate the two other, outer abutments. On approach of the device to an article, contact with the inner abutment causes the limbs to rotate with respect to each other for closure of the device and a catch mechanism, which has cooperating elements 9, 18, 19, arranged on the limbs, bringing the outer abutments into contact with the article. A lifting point is arranged on one of the limbs for lifting the device with a grasped article, eg lifting eye 21 connected to a rope R. The outer abutments face a portion of the article directed away from the lifting point when the device is closed onto the article, so that the article can be lifted. Alternatively the device may comprise three pivotally attached limbs (101, 102,102', fig 7), with the ends of a first limb being pivotally attached to an intermediate part of each of the second and third limbs at respective pivot points. Abutments (114,114', 116,116', fig 7) may be arranged at respective opposite ends of each of the second and third limbs, also for abutting the article when grasped, so that the pivot points are intermediate the abutments. The abutments may be in the form of rollers, pads, trunnion wheels for allowing device to be moved along the article to a new lifting point, or serrated, elliptical wheels for jamming against the article to prevent movement.
