Title: Connectionless communication network with changing topology
Inventor: ROSENBERG CATHERINE
IPC: H04L12/801
Filed: 1997-04-18
Abstract: A connectionless communication network is disclosed which has changeable topology and means for maintaining the available bandwidth when topology changes take place. The network comprises a number of satellites or physical nodes wherein routing of connectionless packets is achieved by selecting paths from a virtual model of the network which is maintained in a connection control system. The virtual model consists of virtual nodes embodied at a given time by a particular satellite. As topology changes take place the virtual nodes become embodied by different satellites which communicate their new virtual identities to their adjacent satellites. Before a message is transmitted from one user to another, a path request is sent to the connection control centre and checks are made to ensure that the user virtual node and the adjacent virtual nodes have sufficient capacity to support the connection. This ensures that bandwidth is maintained. Services may be ATM based.

Title: Pressure sensor with adjustment means
Inventor: BURNS J STEPHEN
IPC: G01L9/00
Filed: 1998-04-06
Abstract: Disclosed is a pressure sensor, for example for a domestic central heating boiler, comprising a rolling diaphragm (15) that adjusts its position in dependence upon the fluid pressure admitted through a pressure port (5). The diaphragm acts against an actuator (7) which adjusts the position of a wiper (20) of a thick film potentiometer, to provide an output voltage in dependence on the admitted fluid pressure. The potentiometer may be calibrated at the factory by rotating an adjustment cap (11) of the actuator (7), which has claw-like projections in engagement with outward projections of part-helical form on a body part (8) of the actuator. There is a one-to-one axial position relationship between the actuator (7) and the wiper (20).

Patent GB-2335216-A (GB)
Title: Extraction of fluid from wells
Inventor: DOUGLAS NEIL IRWIN
IPC: E21B43/12
Filed: 1998-10-29
Abstract: A control system (106) is provided for controlling the flow of hydrocarbons out of a production well. The control system has hydraulic decoders which operate a plurality of chokes. The hydraulic decoders (124) provide actuation signals on receiving hydraulic control pressures within predetermined ranges. The actuation signals operate a hydraulic actuator (120) to open or close a particular choke. In this way chokes can be operated independently. Hydraulic control lines (128) are consolidated by a shuttle valve (134) into a single control line (136). Valves (138) (140) are configured so that, in the absence of control supply (136), valve (138) is closed and valve (140) is open. Valve (138) opens at 1,000 psi and, since valve (140) is open, hydraulic power supply (148) is transmitted through decoder (124) to operate actuator (120) and thus the choke. When the pressure increases above 1200 psi the valve (140) closes. Valves (142) (144) are operated by a pressure between 1500 psi and 1700 psi so that the actuator can move the choke in the opposite direction.

Title: Camera zoom lens barrel control
Inventor: ITO TAKAYUKI
IPC: G03B17/14
Filed: 1996-07-08
Abstract: A zoom lens camera has a zoom barrel 410 with a first lens group L1 and a second lens group L2. During a zooming operation a whole unit moving means 418, for moving the front lens group and second lens group together as a whole in an optical axis direction, is driven by a controlling means 431, and during a focus adjusting operation a relative moving means, for moving the first lens group and second lens group towards or away from each other, is driven by the controlling means 432 to move the first lens group and second lens group to a predetermined position. The controlling means also drives the relative moving means to move the first lens group and second lens group to a focalizing position. After the first lens group and second lens group have been moved to the focalizing position, the controlling means drives the whole unit moving means and the relative moving means in a reverse direction to move the first lens group and second lens group to their positions prior to the focusing adjusting operation.
Patent GB-2334825-A (GB)
Title: Surface static reduction device
Inventor: SHILTON MARK GOLDER
IPC: H05F3/06
Filed: 1997-11-14
Abstract: A radioactive static eliminator gun has a cartridge (7) connected to a high pressure air supply (8). Within the cartridge (7) a radioactive source (6) which generates alpha particles is located coaxially along the central longitudinal axis. The alpha particles collide with the high pressure air stream passing through the cartridge thereby generating ions. With this arrangement the ion concentration is greatest at the core of the air stream which ensures that the greatest number of ions is delivered to the surface requiring static elimination. The radioactive static eliminator gun provides improved efficiency in removing static and is particularly suited to use in paint spraying of metal surfaces where the electrostatic forces at the surface of the metal may not be strong enough to attract ions in the air stream emerging from the gun.

Title: Selection method for transgenic plants
Inventor: DONALDSON IAIN ALASDAIR
IPC: C12N1/19
Filed: 1998-02-05
Abstract: A selection method for selecting from a population of cells one or more selectable genetically transformed cells is described. In the method, the population of cells comprises selectable genetically transformed cells and possible non-transformed cells. Each of the selectable genetically transformed cells comprises a first expressable nucleotide sequence and optionally a second expressable nucleotide sequence. In the method, a component or a metabolic derivative thereof when present in a low concentration in a medium is a nutrient for both the selectable genetically transformed cells and the non-transformed cells. In the method, the component or the metabolic derivative thereof when present in a high concentration in a medium is toxic to the non-transformed cells. The first nucleotide sequence codes for a gene product capable of converting the component or the metabolic derivative thereof when present in a high concentration in a medium to a nutrient for the selectable genetically transformed cells. The method comprises the step of introducing the population of cells to a medium, wherein the medium optionally comprises a high concentration of the component or the metabolic derivative thereof. In the method, the component or the metabolic derivative thereof is a source of both carbohydrate and nitrogen for the selectable genetically transformed cells. Alternatively, in the method if a portion of the component serves as a metabolic substrate and is metabolically converted to a derivatised substrate, then that derivatised substrate is capable of providing an allosteric effect on the gene product.
