Patent GB-2149666-A (GB)
Title: Fumigator
Inventor: AUCHINCLOSS THOMAS RALPH
IPC: A61L9/03
Filed: 1984-11-16
Abstract: A fumigator comprises a base, electrically operated means to heat the base in use and a container mounted on the base, and each upstanding wall 5 of the container consists of a perforated mesh sheet so as to allow volatilised fumigant to escape therethrough. The mesh sheets 5 slide in respective grooves 7 and are thus readily removable from the pillars 4 of the container corners, either individually (Figure 1) or as a basket type unit. In a modification (Figure 3) the perforated container comprises a pillar 9 located centrally inside the unapertured surrounding walls 8 of an otherwise conventional fumigator. <IMAGE>

Patent GB-2168154-A (GB)
Title: Liquid level control and indication
Inventor: GUNN DAVID
IPC: G05D9/12
Filed: 1984-12-06
Abstract: Apparatus for sensing liquid level comprises a heated probe (17) disposed in the liquid container, the presence of the liquid serving to maintain the probe relatively cool while its absence results in the temperature of the probe rising. The probe is associated with a temperature sensor (19), whose output serves to initiate, control of the liquid level and/or shutdown of the boiler or vessel and/or alarm. Such apparatus avoids a false "safe" signal being transmitted due to scale or deposits forming on the probe. The probe may be inclined and contain temperature sensors at each end of the heater. <IMAGE>

The gas produced while burning is purified, therefore such procedure can be used to solve the problem of pollution due to rubbish.
Patent GB-2193673-A (GB)
Title: Linked compound shears
Inventor: MACDONALD GEORGE MARSDEN
IPC: B26B13/26
Filed: 1986-08-12
Abstract: Shears comprise compound levers which are not hinged together at a common axle but have their own separate axles 6 which are separated from one another by the length of a link 7, that is in tension during operation and through the ends of which pass these separate axles. The pressure-exerting axles 4 of the compound levers do not just act at a single point near the ends of the scissor levers but act successively at a series of points 5 near the end of each scissor lever thus enabling the closing of the scissor jaws to be divided into a series of steps, each step corresponding to a full opening and full closing of the compound levers. The separation of the axles allows of an improved operation of the levers whose angular sweep now lies equally on either side of the line upon which maximum leverage occurs thus raising the magnitude of the minimum leverage of the compound levers. <IMAGE>

Title: A radar for use on a platform which may be subject to movement
Inventor: ELLIS ALFRED BRIAN EDWIN
IPC: G01S13/60
Filed: 1987-06-27
Abstract: A radar for use on a platform which may be subject to movement transmits pulses into an area of the ground or sea at two frequencies and mixes the return signals to produce an intermediate frequency signal having a phase dependent on the range to the area, and being used to measure the movement of the platform relative to the ground or sea. The two frequencies may be transmitted as simultaneous pulses, or respective sets of interleaved pulses (Figs 2 and 3) with appropriate delays before phase comparison. Filters 9, (16A, 16B Fig 2, 21A, 21B Fig 3) restrict attention to originals corresponding to movement within a range of azimuth about the boresight. <IMAGE>
Patent GB-2197164-A (GB)
Title: Formatting an answer signal
Inventor: TAKAHASHI CHUSEI
IPC: H04L29/08
Filed: 1987-09-30
Abstract: The answer signal formatting method forms a plurality of answer signals (ACK or NAK signals) 2,4,6,8 ..., interleaved with answer signals 1,3,5,7 ... sent from a called party in response to a ringing signal from a calling party, between data blocks (Fig. 2). The format 1-8 occupies the time normally required for acknowledgement in the prior art. Thus, should an early (ACK) signal, e.g. 2 be correctly received, an answer signal can be received without fail before the data blocks are completely confirmed by the calling party. The method allows correct data communication under bad conditions such as in a mobile radio communication system. e.g., automobile radio communication system. Repeated transmission is required for data received erroneously. <IMAGE>
