Abstract: An expanding pulley infinitely variable transmission 2 has two adjustable sheaves 3, 4, an endless flexible torque transmitting element 5 trained over the sheaves, and at least one hydraulic adjusting cylinder unit 6, 7 for each of the sheaves. The adjusting cylinder units 6, 7 receive pressurized fluid from a pump 14 and the pressure of such fluid, and hence the extent of frictional clamping engagement between the sheaves and the flexible element, is regulated by a torque sensor 16 including a plenum chamber 27 with an outlet 35 having an effective cross-sectional area which is variable in dependency upon variations of torque being applied to the torque sensor by the engine of the vehicle. The energy of fluid leaving the plenum chamber is used to operate a jet pump 37 which draws fluid from a source 38 for lubrication and/or cooling of the transmission and/or one or more clutches 17 forming part of the power train.

Title: Voice band call routing
Inventor: WINCH NICHOLAS RICHARD
IPC: H04M3/533
Filed: 1997-07-29
Abstract: A telecommunications network has routing means whereby a call to an identified user is routed to a User Voice-band Terminating Unit (UVTU) on the network or a further network in response to an in-band identification signal carried with the call. As described when a subscriber 1 calls a personal number customer 2, service switching point 4 sends a message including the calling line identity to a service control point 6 which retrieves from store the latest location or voice mail-box 7 address. An intelligent peripheral 8 monitors the calling line and if it detects a fax tone sends a signal to the service switching point causing the call to be routed to the called customer fax terminal 9.
Patent GB-2319657-A (GB)
Title: Cathode ray tubes
Inventor: TAKA YOSHIO
IPC: H01J29/51
Filed: 1997-11-25
Abstract: Metal foils (30a to 30d) are attached adjacent convergence plates (16R, 16G, and 16B) to which the horizontal deflection magnetic field H is applied from the horizontal coil (21) on the neck portion of a colour cathode ray tube. The metal foils (30a to 30d) form an array centred on the G electron beam with each foil being at an angle of, for example, 45 degrees with respect to the direction X. The magnetic field H applied to the R and B electron beams generates eddy current in the metal foils (30a to 30d). The magnetic field H also generates eddy current in the G convergence plate (16G), and if the force which deflects the G electron beam is weakened by the diamagnetic field, then by providing the metal foils (30a to 30d), the force which deflects R and B electron beams is adjusted to compensate. Hence mis-convergence is corrected easily. Metal rings or coatings can be used instead of foils.

Title: Flexible tuning post for RF cavity
Inventor: KOPAL JOSEF
IPC: H01P1/208
Filed: 1998-02-24
Abstract: An adjustable RF microwave tuning post for use in an RF cavity is comprised of a flexible integrally-formed hollow aluminium cylinder. The Post is made flexible either by having pleated sections around the Post (figure 4), or along the Post (figure 10), or by having a flexible end portion (figure 9). The dimensions of the post may be adjusted either by means of a drive shaft 45, or inflated pneumatically or hydraulically, or it may be temperature controlled. As the post is integrally-formed, there are no metal-metal interfaces in the cavity, which can cause spurious signals.

Title: Routing signals through a wireless communication system comprising a network of linked nodes
Inventor: HUGHES PHILIP THOMAS
IPC: H04L45/42
Filed: 1997-12-18
Abstract: A wireless communication system comprises a network of nodes 2 connected by point-to-point links 3 using highly directional antennae. Each node determines if a received signal includes information for another node and if so, a signal including the information is transmitted to another node. Information is routed or hopped from node to node until it reaches its destination node. Transmission or reception of a signal at any particular frequency by a node takes place on only one link at a time. The nodes may be subscriber stations or repeaters. Various network topologies are described including fully interconnected, linear chain, tree, lattice, hypercube and combinations. Multiple paths for signal transmission can be chosen each consisting of an even number of links to maintain synchronisation of transmission and reception between nodes. A copy of the information may be sent on a different path or the information may be split between two paths. Traffic is routed by addresses added at each node or by a central system controller, and may be determined by congestion or node availability. Each link from a node may be associated with one or more time slots for transmission or reception. At least one link of a node may use a different frequency to prevent interference.
