Title: A method of forming a rigid article from a non-rigid material
Inventor: BARKER TOM
IPC: B29C70/08
Filed: 2000-09-06
Abstract: A method is disclosed for forming a rigid article from a non-rigid sheet of material 1, the sheet of material 1 comprising stretchable fibres, the method comprising the steps of tensioning the sheet of material 1 into a desired configuration, applying a liquid setting agent to the sheet of material 1 in the desired configuration and setting the setting agent such that when the applied tension is removed, the article (5 of fig 3) is rigid and maintains the desired configuration. The setting agent may be a polymer resin and the sheet of material 1 may be held around the periphery of a frame 2 and tensioned by being either pulled or pushed out of the plane of the frame 2. Also disclosed is an article (5 of fig 3) comprising a sheet of pre-tensioned flexible material coated with a setting agent which maintains the rigidity of the article (5 of fig 3) in the pre-tensioned configuration.

Title: Vacuum cleaner with two-stage separation
Inventor: TAYLOR JOHN
IPC: A47L9/20
Filed: 2000-10-07
Abstract: A bagless vacuum cleaner comprises a cyclonic separator 14 arranged to deposit separated dirt and dust in a removable collection receptacle 13, and a tubular filter 23 arranged over the removable collection receptacle 13. The cyclonic separator 14 serves to remove a large proportion of the dirt and dust. Any remaining particles are carried to the next stage, into the passageway extending along the axis of the tubular filter 23 and are then separated, as the air flows radially outwards of the axial passageway and through the filter 23. The upstream surface of the filter 23 is formed of a resiliently compressible material arranged to compress when there is an airflow between the inlet and outlet of the cleaner and to release any dust collected thereon when it recovers its shape upon cessation of the airflow. Upon cessation of the airflow, any dirt and dust collected on the filter is dislodged and falls into the collection receptacle 13, thereby avoiding the need to regularly clean the filter.

Title: A processor element array with switched matrix data buses
Inventor: CLAYDON ANTHONY PETER JOHN
IPC: G06F15/80
Filed: 2000-12-19
Abstract: An array of processor elements 20 is intra-connected via a network of data buses 32, 36 and 42, 46 (30, 40 Fig 1) and switch matrices 55. The data buses are unidirectional (they contain MUXes within their paths) and run in cross matched pairs (left and right 36, 32; up and down 42 46). The buses intersect at switch matrices(constructed from 4:1 multiplexers) which allow for directing of data signals. Several types of processor elements are used, such as ALU, MAC, memory, switch controller and interface elements (Fig 5). The array elements are data driven in that they execute an instruction as a result of receiving data. The processor is suited to digital signal processing (DSP) applications and has power saving features useful when used in applications such as hand held devices.

Title: Instrument for making tests calls
Inventor: KAYES JOHN CLIFFORD
IPC: H04M3/32
Filed: 1999-10-11
Abstract: The invention concerns a telephone test instrument which can be controlled by a remotely located control apparatus to make test calls. The user of the control apparatus is able to monitor the test calls. In one example, a test instrument (50) comprises a telephone unit (60) connected to a test line (52) and two answering devices (61, 62). In response to receiving a call from a remotely located control unit, the answering device (61) connects the control unit to a port of the telephone unit (60). On receiving a signalling instruction message from the control unit, the telephone unit (60) transmits a signalling message on the test line (52). In response to receiving a call from a monitor telephone, co-located with the control unit, the answering device (62) connects the monitor telephone line to another port of the signalling unit (60), which then transmits audio signals between the answering device (62) and the test line (52). Using the control unit and monitor telephone, a test engineer can then cause the test instrument (50) to make test calls on the test line (52).

Patent GB-2378716-A (GB)
Title: Water-based shear-thinning process fluid
Inventor: VAN DER KOOIJ FELIX
IPC: C09K8/05
Filed: 2001-08-08
Abstract: A water-based, shear thinning process fluid comprises clay particles, colloidal particles and a salt, the median diameter (by weight) of the colloidal particles does not exceed 2 m, the preferred colloid being aluminum hydroxide and the preferred clay being bentonite. The Van der Waals interactions between the particles of aluminium and clay organise them into a gel network that increases the viscosity of the fluid when it is static. The viscosity drops significantly when shear is exerted on the fluid. The required rheological properties of the process fluid are maintained, even in the presence of salt. These properties are particularly advantageous for use in oil well drilling fluids. By limiting the size of the colloidal particles to a median diameter <2m, a colloidal suspension is readily formed and their weight-efficiency for thickening the fluid increases. The salt may be NaCl and/or KCl.

Title: Determining an interference relationship between cells of a cellular communication system
Inventor: RATFORD MICHAEL STEPHEN
IPC: H04W16/18
Filed: 2002-12-18
Abstract: The invention relates to a system for determining an interference relationship between cells of a cellular communication system comprising at least a first cell and a second cell. A method comprises the step of dividing (205) an evaluation interval into a plurality of sub-intervals. For each sub interval, the method proceeds to determine (209) a sub-interval simultaneous occupancy related to the correlation between communication in the first and second cell. The sub-interval simultaneous occupancy is determined from an occupancy of each of the first cell and the second cell. A sub-interval potential interference is then determined (209) in response to the interference characteristics in each sub-interval. An interference relationship is subsequently determined from the sub-interval potential interferences and the sub - interval simultaneous occupancies. The interference relationship provides a measure of the impact of interference between the first and second cell suitable for frequency planning.
