Title: Radar video scan converter
Inventor: PEASE WILLIAM M
IPC: G06F7/548
Filed: 1989-07-10
Abstract: A marine radar system has a multi-plane video memory 108 for storing scan-to-scan integrated video data used to raster scan the CRT. A scan converter 106 generates cartesian or x, y addresses for the video memory 108 and synchronous with the generation of each x, y address, generates a range address for reading corresponding video data from an r,  theta  or polar memory. The x, y, addresses or are generated along azimuth sweeps by incrementing one coordinate by a pixel unit and the other coordinate by a trigonometric function. The unit coordinate and the trigonometric function are determined by the 45 DEG  octant in which the azimuth sweep is located. The pixel unit incremented coordinate is offset by one pixel unit from the origin of the azimuth sweep in alternate octants to address pixels along the octant boundaries and thereby avoid display artifacts. <IMAGE>

Title: Rail gun assemblies
Inventor: REYNOLDS GRAHAM ALFRED
IPC: F41B6/00
Filed: 1989-10-13
Abstract: A rail gun assembly having rail electrodes 11, 12 which are of toothed cross-section configuration and an armature 15 which provides an electrical interconnection between the rail electrodes 11, 12. The armature 15 is made up of three electrically conductive portions 24, 25, 26 which are separated by insulators 27, 28. The electrically conductive armature portions 24, 25, 26 are so configured that each of the rear and mid portions 24, 25 in turn makes and breaks contact with a confronting pair of tooth faces 21, whilst forward portion 26 is in constant contact with at least one pair of tooth faces 21. Localised overheating of the armature (15) is therefore substantially reduced (armature portion 26 never carrying a sufficiently high current despite constant contact). <IMAGE>

The inner ends 8 of the vanes 4 are radiused to give a smooth curved surface without edges, enabling the vanes to be distributed symmetrically about the interaction space of the magnetron, even although the vanes 4 are not aligned radially with the centre of the cathode 1. <IMAGE>
Patent GB-895720-A (GB)
Abstract: 895,720. Multiplying-machines. MONROE CALCULATING MACHINE CO. March 24, 1960 [Oct. 2, 1959], No. 10447/60. Class 106 (1). In a totalizer-carriage shifting mechanism for a multiplying machine in which shifting is effected by rotation of a crank 5, the crank is now actuated by a self-centring member 20 extending upwardly through the keyboard and operable forwardly and rearwardly to shift the carriage to the right and left respectively. The member 20 is coupled to a link 14 with a recess 13 normally engaging two of four pins 12 in a wheel 10 geared to the shaft 4 of the crank 5. The link is urged upwardly and towards the central position shown by a spring 17. When the member 20 is operated in either direction, the wheel 10 is rotated through approximately one-eighth of a revolution by the link 14 and then completes its quarter-turn step under the action of the weight of the carriage on the crank 5. During the final movement, the next pin 12 depresses the link 14 to permit the spring 17 to centralize it again. Application 27231/12 is referred to.

Title: An image forming method using a thermal transfer.
Inventor: UENO TAKESHI
IPC: B41M5/52
Filed: 1992-05-13
Abstract: A dye-receptive layer on a transfer film is transferred to a print sheet and then dye layers on a dye transfer film are superposed on the dye-receptive layer and subjected to an image forming operation of a thermal head so that an image is transferred to the dye-receptive layer. In order to transfer the dye-receptive layer to the print sheet uniformly to enable subsequent formation of an excellent dye image, the quantity of thermal energy being applied by the thermal head to the transfer film is decreased with elapse of time. This principle can also be used for transferring a protective layer to the print sheet on which a dye image has been formed. The variation may be produced by changing the input of energy to the thermal head, or by change of speed of the substrate, or by change of applied pressure (Figs 2a-e). <IMAGE>

IPC: B66F1/02
Filed: 1993-02-23
Abstract: A jacking apparatus has a tubular metal outer casing (10) with a tubular collar (20) located in its upper end. A first tube (18) is slidably disposed with respect to the collar (20) and the downward displacement of the member (18) can be restricted by means of a locking ring (22) which is screw-threadedly located on the exterior surface of the member (18). A second extension member (24) projects into, and is screw-threadedly connected to, the first extension member (18). The apparatus is operated by unscrewing the inner extension member (24) until its lower end (30) engages with the end of a retracted jack (16). The jack is then extended and the locking ring (22) is moved along the outer extension member (18) until it engages the upper end of the collar (20), thereby securing the outer extension member in position. The jack (16) is then retracted, and the cycle is repeated, thereby making it possible to provide a total extension which is greater than the maximum stroke of the jack (16). <IMAGE>
