Patent GB-2294327-A (GB)
Title: Roundness measuring
Inventor: SCOTT PAUL JAMES
IPC: G01B21/20
Filed: 1994-10-18
Abstract: A machine measures the roundness of an object (23, Fig. 1) as the latter is rotated on a turntable (7) without the need to centre the object precisely on the table axis S. The object has a periphery 49 which is nominally round with a centre W. The machine measures the position of a plurality of points on the actual periphery and determines the circle 51 which best fits the measurements. It then converts the measurements (x) to distances (m) from the best fit circle. An improved algorithm for determining the best fit circle is used in place of the limacon fit. Calculated differences I between the measured surface position and the best fit circle are corrected for the effect of measuring the difference in the direction towards the centre S of rotation of the turntable instead of in the direction towards the centre W of the circle 51. Data values are calculated representing points at equal angles  theta  around the centre W of the best fit circle rather than equal angles  alpha  around the centre S of rotation of the turntable. The improved accuracy of correction allows the machine to tolerate greater eccentricity of the workpiece relative to the turntable, reducing the necessity for accurate centring of the workpiece. <IMAGE>

Title: Electrochemical deionisation using electrochemical ion-exchange to remove ions from feed solution or in cathodic protection of reinforcing bars in concrete
Inventor: HILL MICHAEL RAPHAEL HUGH
IPC: B01D61/48
Filed: 1995-04-26
Abstract: Under the influence of an electric field, ions are adsorbed into, are stored within and pass through a permeable layer (54, 64) of particulate ion-absorbing material and binder, the sheet being several millimetres thick. Water from the feed solution also permeating through the layer (54, 64), so a concentrated solution of the ions emerges from the rear (58) of the layer. The cell does not require separate sources of feed and eluant solutions and can be operated substantially continuously. In a modified cell the flow path for the feed solution passes through a highly porous ion exchanger structure eg. foam blocks (77, fig. 5) containing ion-exchanger which may be located between two such microporous layers (54, 64). Absorption in such a cell may be effective in the absence of an electric field, elution requiring the periodic application of the electric field. In cathodic protection an external anode is spaced apart from the reinforced concrete by a layer (106 Figs. 8, 9) of particulate anionic exchange resin in the OH<-> form and binder, chloride ions attracted to the anode displaying OH<-> ions. <IMAGE>

Title: Method of determining edge positions
Inventor: MAROLD THOMAS DIPL PHYS
IPC: G01B11/02
Filed: 1995-12-20
Abstract: The edge measurement method involves using the signals from a photoreceiver array to scan a light-dark structure to determine regions of four adjacent photoreceivers (i,i+1,i+2,i+3), in the middle of which is at least one edge. The type of edge, i.e. light-dark, or dark-light e.g. (schwartz-weiss), is determined from the four signals. A parameter (Mi) is formed as Min or Max (Yi,Yi+1) according to the type of edge and type of brightness. A parameter (Ma) is formed as Max or Min (Yi+2,Yi+3) depending on the type of edge and brightness. The position x of the edge w.r.t. the line separating the photoreceivers (i+1,i+2) in units of photoreceiver dimensions is derived from x = (Mi-Yi+1-Yi+2+Ma)/(Ma-Mi).

Title: A lens mounting arrangement having a resilient link
Inventor: EDWARDS HYWEL
IPC: F16H35/00
Filed: 1997-03-14
Abstract: A lens mounting arrangement 10, for moving a magnification change carriage within an optical telescope, comprises a lens carriage 12 coupled to a motor 20, eg limited angle torque motor, via a resilient link/sprung fork 26 which engages a peg 22 on an upper surface of rotor 24. By energising the motor 20 such that the rotor 24 moves through 180{, the carriage is moved linearly along track 16 between end stops 18, 19 which are adjusted to provide precise control of the lens carriage. When the end stops 18, 19 are engaged the resilient link 26 deforms so that excess movement of the drive is eliminated. As the carriage 12 approaches an end stop (eg either 18 or 19) the gear ratio increases towards infinity as the motor 20 travels over centre, and when passing through the centre the gear ratio is 1:1, thus a high linear force is developed near each end stop 18, 19 which ensures sufficient loading of the resilient link 26.

Title: Transmitter with power control in both if and rf sections
Inventor: RICH RANDALL W
IPC: H03G3/30
Filed: 1997-08-11
Abstract: A gain controller (130) for a radio frequency (RF) transmitter (102) controls a power level of a signal (123) transmitted within a predetermined range of output power levels. The gain controller (130) provides the first gain control signal (131) and the second gain control signal (133) responsive to an output power level control signal (150). The first gain control signal (131) controls a gain of a first variable gain stage (114) to vary the power level of the transmit signal (115) at an intermediate frequency causing the output power level of the transmit signal (123) to vary over a lower range of the predetermined range of output power levels. The second gain control signal (133) controls a gain of the second variable gain stage (120) to vary the power level of the transmit signal (121) at a radio frequency causing the output power level of the transmit signal (123) to vary over an upper range of the predetermined range of output power levels. The power control circuit (130) is advantageously utilized in a code division multiple access (CDMA) radiotelephone (100) to provide power control over an 85 dB range of power levels while minimizing sideband noise emissions, current drain, and complexity of the RF transmitter (102).

Abstract: A thermostat for controlling an immersion heater in a hot water tank comprises a tube (10) with a switch assembly (12) mounted at a first end of the tube. A rod (14) extends within the tube and is secured to it adjacent its second end (16). The rod (14) has a coefficient of thermal expansion different from that of the tube (10) and is operatively coupled to the switch assembly (12) so as to cause the switch assembly (12) to change state in reaction to a change of temperature of the tube (10) There is carried on the rod (14) a first supporting member (42) formed from a material of a high melting point and a second supporting member (44) formed from a material with a melting point below that temperature which would be dangerous if exceeded in use. A spring (50) is trapped in compression between the first and second supporting members (42,44). An actuating assembly (60, 64)) is operable under the action of the spring (50) on its release in the event of the second supporting member (44) melting, to cause the switch assembly (12) to change state so as to prevent further heating. If a first set of contacts (30) normally actuatable by the rod (14) fails to open, the second supporting member (44) melts when the water temperature exceeds a predetermined value to cause a second set of contacts (82), in series with the first set of contacts, to open.
