Title: Testing AC Installations
Inventor: SMITHSON EDWARD
IPC: G01R31/02
Filed: 1989-12-29
Abstract: Apparatus for checking an electrical installation (not shown) having an AC supply protected by a residual current circuit breaker (not shown) operates by applying (11, 15, 7) a disabling current to the RCCB, the disabling current (Figure 2) rising at the time of connection and following an alternating form and fading gradually so that on completion of checking the final amplitude is zero. The disabling current saturates the RCCB and has a frequency considerably less than the supply frequency. Checking of the installation is performed by a measurement circuit (12). <IMAGE>

Title: Motion compensated interpolation of images having choice of motion vectors
Inventor: DAVID MORGAN WILLIAM AMOS
IPC: G11B27/032
Filed: 1990-11-15
Abstract: The method comprises the steps of:-     developing at least one local motion vector for each pixel in the output image indicative of the estimated motion of that pixel; determining, as at least one global motion vector, at least the most frequently occurring local motion vector for the whole output image; determining, for at least one portion of the output image, as at least one respective intermediate motion vector, at least the most frequently occurring local motion vector within that portion of the image; selecting, for each pixel, an output motion vector from the respective local motion vector, intermediate motion vector for the portion of the image containing the pixel and the global motion vector; and determining the value of each output pixel by interpolation between pixels of input images using the selected output motion vector.   This approach allows the method to deal satisfactorily with medium-sized objects in the image. <IMAGE>

Title: Settling tank with vortex valve outlet
Inventor: FAGAN GARRY WILLIAM
IPC: B01D21/24
Filed: 1992-10-06
Abstract: A settling tank includes a vortex valve, in the form of a horizontal cylindrical chamber with a tangential inlet 51 and axial outlet 52, to remove floating matter from a region thereof. In Figs. 1 - 3 the chamber extends radially between an annular dip plate 8 and the outer wall of the tank, at the downstream end of a baffle 14 which contains matter to flow beneath radial overflow 7 (See GB 2223957A). Inlet 51 extends the whole length of the valve chamber to collect and discharge matter flowing along the underside of baffle 14. This happens only when the overall flow in the tank, and hence the surface level therein, is high. In Figs. 4, 5 the chamber extends across the top of a rectangular tank, with a baffle directing surface matter downwards into the inlet. <IMAGE>

Title: Moving aircraft on the ground.
Inventor: MELNICK IRVING
IPC: B64F1/22
Filed: 1993-04-01
Abstract: To move an aircraft, a powered tractor (6) is coupled to the nose wheels (4) by way of a towbar (8). In the cab of the powered tractor (6), control means are provided which power an umbilical (10) which has an electrical connector (12) which is connected at (14) to an electrical control system for the braking system for the main wheels of the aircraft so that the control means in the tractor (6) controls the aircraft braking system. Movement of the powered tractor (6) backwardly or forwardly moves the aircraft (2) accordingly. However, deceleration or stopping of the aircraft (2) is by braking the main wheels of the aircraft by actuation of the main braking system from the control means in the tractor (6). This avoids putting undue stress on the aircraft nose gear and enables movement of the aircraft by a single operator. The powered tractor (6) may engage and lift the nose wheels (4) instead of using a towbar. <IMAGE>

Dynamic seal means 72 are provided between seal element 26 and tubular elements 22, 24 to maintain a fluid seal during axial movement of seal element 26. Alternatively locking may be achieved by external spring-biased pins (112, 114 Fig. 16) engageable in receptacles (126, 128) on one of the joint elements. <IMAGE>
