Filed: 1997-05-01
Abstract: A two way radio communication system 20 includes a plurality of radio units 22,24,26,28,30 communicating via at least one communication resource 34, 36. A first radio unit of the plurality of radio units includes a receiver 48 for monitoring available resources of the at least one communication resource 34,36 and a processor 46 for maintaining a prioritised list 45 of the available resources and for selecting the one with the highest priority when the said radio unit wishes to enter into communication with at least one second radio unit. In this manner, an optimised communication resource is selected for the communication. The first radio unit may transmit its priority list to the second radio unit(s) which may then choose a channel which is also free from interference at its end. Also mentions group calling, wherein the priority list may be transmitted to more than one intended recipient.

Title: Producing isometric view from manipulated plual planar views in CAD system
Inventor: SEKI NOBUHIRO
IPC: G06T19/00
Filed: 1997-06-04
Abstract: To obtain an isometric view on the basis of the data of plan view, the main input means 300 enters designated planar view, plane stand point Pa to be specified in relation to the designated planar view above and the direction of the planar view by a simple manipulation on the display 100, together with display standard point P10 for the desired isometric view obtained through the operating means 20. Then the model projection plane input means 300 enters designated plane of the three model projection planes composing the isometric view and the direction of the designated plane in the same manner. A table is equipped, which contains ratio of the major axis and minor axis of each projection planare obtained, depending on the angle of each projection. The operating means 20 overlaps the system of coordinates of 45' rotation of the planar view on the system of coordinates of the major axis and minor axis of the ellipse on the projection plane, and obtains a projection view by operating by multiplying by the ratio a/b of the major axis (a) and minor axis (b) in the major axis direction and minor axis direction, and thus obtained projection view is matched with the plane standard point P10 on the planar view at the display standard point Pa, and the isometric view is displayed on display 100 so that the direction on the planar view may coincide with the direction of the model projection plane. A projection view which corresponds with rotating angle of model projection plane 1 currently on show on the display 100 is obtained. By means of the angle input means 400, the rotating angle of model projection plane 1 is entered and after this procedure the angle operating means 30 computes the ratio of the major and minor axes of each projection plane. The model projection planes are displayed in rotation about at least one of the basic three axes for composing the model projection planes. Hence, the model projection planes corresponding to the inclination of the planar view to be projected appear on the display 100.

Title: Error-correcting torque sensor
Inventor: NG HARRIS
IPC: G01L3/10
Filed: 1998-01-16
Abstract: A torque sensor is provided for measuring the amount of torque being applied to a rotatable shaft (102) fitted with a torsion bar between two separates shaft segments. The sensor includes first rotor (112) attached to a first shaft segment (104) such that angular rotation of the first segment is translated to the rotor. A second rotor (124) is attached to the second shaft segment (106) such that angular rotation the second shaft segment is translated to the second rotor. The first rotor supplies two pairs of signal voltage references circumferentially spaced around a surface of the first rotor. At least one resistive track (128) having a uniform linear resistance extends between the voltage signal references of each pair. A pair of contact carriers (116,118) are positioned between the first and second rotors. Surface features formed in the contact carriers and the first rotor couple the contact carriers to the first rotor such that the contact carriers are constrained to move anullarly around the central axis of rotation of the first rotor. The contact carriers are anullarly driven by the second rotor. First and second signal contacts are mounted to the contact carriers, and are configured to engage the at least one resistive track at points between the first and second pairs of signal voltage references respectively. Output voltage signals are developed from said first and second signal contacts proportional to the relative position of said contacts between said voltage reference pairs. A method of correcting signal errors introduced from misalignment of the two shaft segments is provided by subtractively averaging the two independent voltage signals.

Title: Production of a high purity hydrogen gas stream and a high purity carbon monoxide gas stream
Inventor: KAPOOR AKHILESH
IPC: C10K1/32
Filed: 1999-02-23
Abstract: A process for the production of a product stream of high purity hydrogen gas (20) and a product stream of high purity carbon monoxide gas (44) is described. A first stream of a gas mixture comprising hydrogen, carbon monoxide, carbon dioxide and optionally up to 10% by volume of methane, obtained from hydrocarbon reformer unit A, is reacted with steam in water gas shift reactor B thereby causing at least part of the carbon monoxide present to react with the steam to form a hydrogen-enriched intermediate stream. This intermediate stream is first dried in dryer C and then a high purity hydrogen product gas is obtained by pressure swing adsorption in unit D using a carbon dioxide-selective adsorbent. A second stream of the gas mixture produced in reformer unit A, after drying in dryer E, is subjected to pressure swing adsorption at elevated pressure in unit F in order to produce a first non-adsorbed hydrogen-enriched stream (36) which is added to the hydrogen-enriched intermediate stream (at 18) immediately prior to its entry into unit D. Partial depressurisation of unit F produces a second waste steam containing carbon dioxide and, if present, methane (40), and further depressurisation of the unit F produces a stream of high purity carbon monoxide gas (44). The absorbed carbon dioxide in unit D and that (40) obtained from unit F is recovered and recycled for use as fuel gas for unit A.
