Patent GB-2212277-A (GB)
Title: Gas flow meter
Inventor: JACKSON PETER
IPC: G01F1/32
Filed: 1987-11-07
Abstract: A gas mass flow meter comprises means for measuring mass flow at low flow rates and velocity at high rates with an overlap region in which the outputs from the two means are combined to provide the gas density. The latter is then combined with the velocity to give mass flow at high rates. A thermal type flow meter is used to measure low flow rates, a vortex flowmeter to measure velocity. The outputs are combined in a microprocessor. Temperature may be monitored and used to apply a correction without waiting for flow in the overlap region to re-occur. A proportion of the total flow may be passed through the measuring means which may form part of a domestic gas meter.

Filed: 1989-02-18
Abstract: A strategic board game, comprising a number of playing positions, overlapping each other in small groups, the groups each being within one of a number of areas 1 to 5. The positions each relate to one of the areas. The object of the game is to be the first player to dispose of all ten playing pieces, by placing them onto the playing positions.

Patent GB-2221997-A (GB)
Title: Leak detection
Inventor: CHILD JOHN WILLIAM
IPC: G01M3/00
Filed: 1989-08-03
Abstract: In a method to detect and locate a leak from a duct or tube enclosed by a casing e.g. a tube in shell heat exchanger, the casing is viewed by an infra red camera, while a pressurised liquid just above its normal boiling point is caused to flow along the tube. The liquid might be liquid nitrogen at about 77 K. The portion of the casing facing any leak will be hit by a jet of liquid, and so will be of significantly lower temperature than the remainder of the casing. The duct or tube is throttled at one end by a nozzle and initially, the duct or tube being at a higher temperature than the liquid, only nitrogen gas flows along the duct or tube to emerge from the nozzle. Within a few minutes liquid nitrogen emerges from the nozzle whereupon the liquid jet emanating from a leak in the tube or duct will impinge on the casing and rapidly cool it locally.

Title: Improved electro-active composite poling efficiency.
Inventor: CHILTON JOHN ANDREW
IPC: H01L41/37
Filed: 1989-08-30
Abstract: This invention describes a technique for improving the effectiveness of 'poling' of a composite material and hence its degree of electrical activity. The technique utilises a preferential uptake of a polar fluid by one of the phases to reversibly alter the resistivity balance between the materials within the composite. The fluid may be driven off after poling by, for instance, vacuum drying to allow operation of the material as a low electrical loss material.

Patent GB-2253520-A (GB)
Title: Array antenna and stabilized antenna system
Inventor: EGUCHI KOUCHI
IPC: H01Q1/18
Filed: 1991-10-14
Abstract: An array antenna 114 can control directions of beams by phase-shifting signals received and/or transmitted by a plurality of antenna elements 110. When the antenna elements 110 are arranged two-dimensionally, sidelobes and beamwidth are determined according a distance between two adjacent antenna element columns. The distance between the adjacent columns can be reduced by arranging the antenna elements in a staggered manner, thereby suppressing the sidelobes, and enlarging the width of beams around an XEL axis. A stabilized antenna system (156), Fig. 5, controls the direction of the array antenna 114 and beam directivity by compensating for inclination of a moving platform, which supports the antenna 114, so that the array antenna 114 can always track a satellite reliably. <IMAGE>
