Patent GB-2203018-A (GB)
Title: Communications system
Inventor: HAN KUIXUAN
IPC: H04B7/26
Filed: 1987-07-17
Abstract: In a cellular radiotelephone system, a geographical area is divided into radio zones, each of which comprises a cell set, and a plurality of transponders which relay signals from portable units to the cell set, and from the cell set to the portable units. The use of transponders reduces the talk-back distance. This, in turn, results in a reduction of the power requirement of the portable units, which can therefore use smaller batteries and smaller transmitter components with a resulting reduction in size and weight. No hand-off takes place as the portable unit moves from transponder to transponder within the radio zone. Thus, the subdivision of the radio zone into transponder areas does not overburden the hand-off supervisory system. The number of channels assigned to a radio zone can be changed to suit conditions. In addition, however, the shapes and sizes of the radio zones can be varied with changes in user dispersion, to reduce the likelihood that all assigned channels in a given radio zone will be in use at the same time. The change in shape and size of a radio zone is carried out by breaking the communication link between a group of transponders and one cell set, and establishing a communication link between the same transponders and a different cell set. Hand-off occurs when a portable unit moves from one radio zone to another. The portable unit generates a hand-off request signal when the magnitude of the downlink voice signal falls below a preestablished level.

Title: Annealing gallium arsenide substrates
Inventor: WARWICK COLIN ALAN
IPC: H01L21/324
Filed: 1988-02-04
Abstract: Method of producing a GaAs or GaALAs field effect transistor (FET) includes the steps of providing an ion implanted donor channel (3) in a semi-insulating GaAs substrate (1). Suitable ions are of Si, Ge, Sn, C, Be, Mg, Zn, Cd, Hg. A Ga doped or Ga and Al doped SiOx (x = 1 to 2) capping layer (4) is grown on the substrate. The capped substrate is then heated to about 800 to 1300 DEG C for up to 10 hours or more. This anneals the ion implantation damage, out-diffuses a controlled amount of Ga, and creates sub-lattice vacancies for the donor atoms. Source, drain, and gate electrodes (7,8,10) are then formed on the channel. The presence of Ga in the SiOx capping layer allows a controlled amount of Ga to diffuse from the implanted channel during annealing. <IMAGE>

Title: Transporting a liquid past a barrier
Inventor: FRAY DEREK JOHN
IPC: C25C3/04
Filed: 1988-03-29
Abstract: The invention provides a method of transporting a liquid A past or around a barrier, by adding a solute S to liquid A on one side of the barrier and correspondingly removing solute S from liquid A on the other side of the barrier, the solute S being such as to change the density of the liquid A when dissolving in it, thereby providing a motive force for its motion around the barrier. An example of the application of the invention is in a two-part electrolytic cell (1) comprising electrowinning and electrofining half cells (2 and 3, respectively), wherein the metal, solute S, is electrowon into a liquid (16,16a), liquid A, on one side of the cell's common electrode (4), the barrier, in the electrowinning half cell (2), and electrolytically removed from the liquid (17,17a) on the other side of the common electrode (4), in the electrorefining half cell (3).

Patent GB-2242450-A (GB)
Title: Tree paved surround support system
Inventor: FINLAY JOHN
IPC: E01C9/00
Filed: 1990-03-28
Abstract: A problem exists which leads to settlement of paving works which have been constructed directly over the soil pits of newly planted trees. The problem is caused by a conflict of needs. The paving needs well compacted ground below it, whilst the tree itself needs lightly compacted soil around it in order not to damage its root system during planting operations. This support system carries the load of the paving and the paving base materials away from the soil surrounding the tree roots directly below it, to a number of remote load-bearing points which do not interfere with the tree root system. This is achieved with layers of structural mesh 1 and 2 which retain the paving works, 7, 8, 9 and 10 and transfer their load via a beam 3 network to mini load-bearing friction piles 5 driven into firm ground beyond the perimeter of the tree pit 6a. <IMAGE>
