Title: Performing raster operations on patch formatted pixel data
Inventor: TREVETT NEIL FRANCIS
IPC: G06T1/20
Filed: 1988-03-23
Abstract: A system and method for performing raster operations in a patch access environment utilizes two or more source patches to produce an Y shifted destination patch. Even though the present invention operates in a patch access environment, it can form a destination patch by merging groups of pixels not residing within the same patch boundaries. The Y shifting and merging used to form the Y shifted destination patch can be done on a patch plane basis or on a patch basis. A line of Y shifted patches is stored in a memory. A second contiguous line of Y shifted patches is also stored in the memory. The stored lines are merged and Y shifted output patches can be read out of the memory in a page mode fashion. Boolean or arithmetic operations can be performed between the Y shifted patch and pre-existing data within a destination patch area so as to produce the Y shifted destination patch. <IMAGE>

Title: Sensors and calibration device
Inventor: TAVENER JOHN PETER
IPC: G01K7/18
Filed: 1988-09-23
Abstract: A high temperature platinum resistance thermometer comprises an elongate quartz tube 2 within which is positioned the platinum winding 1. A positive potential offset voltage e.g. of 6 to 10 volts is applied to the platinum winding 1. Terminals 3 and 5 of the winding 1 can be connected to a bridge circuit so that the measured resistance of the platinum winding 1 is indicative of the temperature thereof. A calibration device comprises a cylindrical quartz tube 10 having a graphite crucible 12 positioned therein. A positive offset voltage is applied to the crucible 12 or to the partly molten metal therein. The calibration device can be used to calibrate the thermometer when inserted into the recess in the direction of arrow A. Application of the positive offset voltage has the effect of stopping or at least alleviating the migration of metallic vapours through the quartz sheath and so reducing combination of the metal part of the sensor or of the metal within the crucible of the calibration device. <IMAGE>

Title: Sewage treatment plant
Inventor: SKILLING ANDREW JOHN
IPC: C02F3/04
Filed: 1988-10-15
Abstract: Sewage treatment plant suitable for installation below ground has a primary settlement chamber 12, a percolating filter chamber 13 and a secondary settlement chamber 14. Sewage introduced through inlet 19 is transferred by an air lift to the top of the filter chamber 13, and is allowed to percolate over filter media 28 whilst air is pumped to the lower region of that chamber 13, to rise through the percolating liquid. Pump 32 serves to transfer filtered liquid to the secondary settlement chamber 14, and a further air lift then discharges liquid from that chamber to a water-course. Solid matter settling in secondary settlement chamber is transferred back to the primary settlement chamber 12, to prevent the accumulation of solids in the secondary settlement chamber and to ensure that there will be a relatively constant liquid flow over the filter media 28. <IMAGE>

Title: Take-down control in knitting machine
Inventor: PRATT DAVID ROGER
IPC: D04B15/88
Filed: 1989-03-30
Abstract: The drive shaft (18) of take down rollers (12, 14, 16) of a circular, e.g. Raschel, knitting machine is coupled both to the machine drive (33) and to adrive motor (42) whose speed is controlled by a control unit so that during knitting, e.g. of tights, the motor (42) is driven at a preselected varying speed to increase and decrease tension and thus the diameter of the fabric. The control unit controls the motor speed by a potentiometer which in turn is adjusted by a servo motor whose direction of motion is determined by a process controller while a second unit controls the speed of the servo motor and thus the rate of change in the speed of the motor (42). The motor (42) and drive (33) are connected to the shaft (18) through freewheel couplings (34, 38). <IMAGE>

Patent GB-2236449-A (GB)
Title: Motion estimation for television signals
Inventor: KNEE MICHAEL JAMES
IPC: G06T7/20
Filed: 1989-09-20
Abstract: In apparatus for processing television signals for transmission, motion estimation is carried out by calculating 10 a correlation function C(x, y) for motion vectors (x, y) using information from signals representing a previous picture and the current picture. The best integer-pixel estimate (X, Y) for the motion vector is determined 12 from the calculated values of C(x, y). From the calculated values of C(x, y) the region relative to (X, Y) in which the best sub-integer-pixel estimate (X', Y') of the motion vector is to be found is determined. Subsequently values of the correlation functions C(x, y) for those sub-integer pixel motion vectors which are in the said region are calculated 18 and compared 18 so as to find (X', Y'). Since only the sub-integer estimates of the motion vector within the region identified from the integer-pixel estimates are calculated, the only previous-picture pixels which need to be accessed for the sub-integer pixel search are those which would be needed if a motion compensated version of the previous picture were required. Furthermore, only four streams of interpolated pixels need be generated and corresponding mean absolute error values calculated and compared. <IMAGE>

Abstract: A device for use in the fitting and removal of large springs 1 (Fig. 3) on motor vehicle axes has a tube 3 screw-threaded onto a spindle 2 connected with an articulated joint 17 to a threaded stud 15. The tube 3 rotatably supports a tray receiver 31 for engagement with a spring plate on the vehicle and having a hand grip 32. An intermediate disc 21 with projections 24, 25 is non-rotationally but axially displaceably-mounted on the stud between a clamping nut 20 and an axle- engaging abutment 19. The disc 21 is mounted on the stud 15 with a tongue and groove engagement 26, 28 and the projections 24, 25 cooperate with corresponding recesses 47 of a disc 46 (Fig. 3) secured to the vehicle axle to prevent rotation of the stud relative to the axle on tightening of the clamping nut. The upper end of the stud passes through a hole in the axle and is clamped non-rotationally on cooperation of projections and recesses of discs 21 and 46 on tightening of nut 20. The tube 3 may then be screwed up on spindle 2 to force the receiver 31 against the spring plate or cup 36 at the lower end of the spring to permit unbolting of said spring plate. <IMAGE>
