Title: Tracking
Inventor: SCHWEYER NIKOLAUS
IPC: G06T7/00
Filed: 1989-08-22
Abstract: Target recognition apparatus utilising the principle of edge detection has an imaging sensor, 1, a signal processing circuit 5 and an evaluation circuit 6-10, for the performance of a grey-value analysis of the output signals of the imaging sensor, the signal processing circuit containing threshold value transmitters for the brightness transition and for the local extreme values, a reduction to three values (bright/required/dark) taking place in the signal evaluation circuit, an area centre of gravity of the target being determined by producing co-ordinates of the target. The computer for target recognition, after the locating operation and by comparing the measured parameters with the stored parameter, also evaluates the signs Fig. 2b of the resulting image in order to determine the direction of the target, using edge points situated on a straight line, which are obtained from the computer, in addition to a binary image, defining edges and non-edges.

Title: Foamed jacket production
Inventor: DAVIES HARVEY
IPC: B29C44/32
Filed: 1989-12-04
Abstract: Polymeric material is foamed in situ to produce a foamed jacket for a pipeline, for use, for example, in the petrochemical industry. The jacket is formed between a pipeline 1 or 31 and a coaxial sleeve 2 or 32 by injecting foam-forming ingredients into the space between the pipeline 1 or 31 and the sleeve 2 or 32, by means of at least one foaming head 17 or 44 which is driven progressively along the space between the pipeline and the sleeve as the foam-forming ingredients react to form a foam. The foaming head may comprise an annular jig 17 which can be retracted by a spool 12, a manifold 44 mounted externally of the sleeve on a jig 30 provided with a sleeve splitter 42 and welder 51 to allow insertion of the foam or a jig (60, Fig 7 not shown) provided with a guide (80) and welder (66) for applying foam and a wrap-around sleeve (64). <IMAGE>

Title: Electrical power measuring devices
Inventor: JONES ALAN JOHN
IPC: G01R21/133
Filed: 1990-01-05
Abstract: In an electrical power measuring device, analogue samples of a current supplied to a load are applied (1, 5, 7, 9, 23) to one input of a multiplying digital to analogue converter (MDAC) (21) and pulse code digital signals representing successive samples of the voltage supplied to the load are applied (3, 11, 13, 15, 17) to the other input of the MDAC. Digital output signals representative of the product of current and voltage samples are then produced by an analogue to digital converter (15) from the analogue output of the MDAC. The analogue to digital converter (15) is used on a time-sharing basis (13) also to provide the digital signal applied to the input of the MDAC. <IMAGE>

Title: Pressure and temperature sensing systems
Inventor: BAKER PETER DONALD
IPC: G01D5/353
Filed: 1990-06-28
Abstract: A probe 4 has an inlet 7 and outlet 8 by which gas or liquid flows over an optical sensing element 3 in the probe. Broad band optical radiation is supplied to the element 3 and transmitted radiation is supplied to three photodiodes 11 to 13 responsive to radiation at different wavelengths. The transmission characteristic of the element 3 varies in different ways with change in temperature and pressure respectively. A store 200 of temperature and pressure against amplitude of radiation at different wavelengths is addressed by the outputs of the photodiodes to give an indication of pressure and temperature at the element. Alternatively a sensing element in the form of a vibrating device is employed, the resonant frequency varying with pressure and the Q varying with temperature. <IMAGE>

Patent GB-2265599-A (GB)
Title: Can opener
Inventor: FUNG LIN
IPC: B67B7/72
Filed: 1992-04-01
Abstract: A can opener consists of two body members 1, 2 pivoted together and each provided with a handle 1a, 2a, a rotatable cutting wheel 6 and a drive wheel 4. The rotatable cutting wheel is mounted on one body member 1 in an inwardly offset position relative to the lengthwise axis of body member 1 so that as the arms are moved pivotally towards one another the rotatable cutting wheel moves directly towards the drive wheel, in direction of arrow B, at right angles to the can wail. The mounting of the rotatable cutting wheel on the arm reduces the risk of the rotatable cutting wheel being distorted in use, as it cuts into the can wall below the lid. A raised wall 19 may surround the cutting wheel to protect the user and a projection 20 may contact the can lid during use. <IMAGE>

Title: Digital data rounding.
Inventor: NAKATA TETSURO
IPC: H04N19/136
Filed: 1993-08-17
Abstract: A data rounding circuit (10) for rounding ten-bit digital data (a) to eight bits includes a bit pattern generator (22) for generating at least four bit patterns PTN0 to PTN3 each comprising at least two single-bit samples, wherein one of the fixed bit patterns PTN0 to PTN3 is selected in accordance with the value of the low-order two bits (c) of the ten-bit digital data (a) to be rounded and added to the high-order eight bits (b) thereof to produce rounded eight-bit data (e). The circuit can be used to round 10-bit digital video signals to 8-bit data where the use of fixed bit patterns improves the overall picture quality. In addition, by changing the ordering of the single-bit samples in a fixed bit pattern, the adverse generation of an inherent vertical bit pattern can be prevented. A method of recovering the truncated bits to restore the original ten-bit data is also disclosed. <IMAGE>

Abstract: Control of the variable volume ratio (Vi) of a helical screw compressor (2) having meshing screw rotors (17/18) in a casing (20, 21, 22) is obtained by means of a slide valve (3) positioned in the depression at the zone of meshing of the rotors (17/18) to control a fluid port (12), a stop (4) for the slide valve (3), and a biasing spring (5) between the stop (4) and the slide (3). Fluid actuators (6, Fig 3B), (7) position the slide (3) and stop (4) respectively, and control means are provided for controlled setting of the stop (4) against the force of the basing spring (5). This control means can comprise a pressure controlling needle/orifice device (14/15) at the piston (10) of the stop fluid actuator (7) whereby the position of the piston (10) can be set by adjusting the needle to adjust the stop position. Alternatively (Fig 6) an abutment device (44) can be set by the stop fluid actuator (7) to regulate the position of the stop (4).   A closed loop control system (Fig. 5) responsive to compressor operating parameters, eg pressure ratio and slide valve position, adjusts the slide value to adjust compressor load to achieve optimum internal volume ratio. <IMAGE>
