Title: Co-ordinate tables
Inventor: BLOUNT ERIC ALBERT
IPC: B23Q1/54
Filed: 1982-10-26
Abstract: Present-day manipulators of the conventional "robot arm" variety are usually not entirely successful; the robot arm, while being capable of performing the gross movement of its human counterpart, is invariably less able to perform the very fine movements increasingly required in modern assembly work. However, fine positioning capability may be achieved by mounting upon the arm, intermediate it and the tool it is to operate, a co-ordinate table (15) able to provide the full range of fine positioning required. The present invention suggests a novel form of coordinate table (15) which comprises: a baseplate 22 having a first eccentrically-bored ring 33 drivably mounted thereon for rotation about the ring's 33 external surface axis; a second eccentrically-bored ring 42 mounted coaxially with the first ring's 33 bore 34 for rotation about that bore's 34 axis, the eccentricity of the second ring's 42 bore 44 matching that of the first ring's 33 bore 34; and a toolplate 62 drivably mounted on the second ring 42 via a cylindrical toolplate support 64 itself mounted coaxially within the second ring's 42 bore 44 for rotation about that bore's 44 axis; there being means 52-54 to prevent uncontrolled relative rotation of the two plates 22, 62 while permitting their relative linear translocation. <IMAGE>

Patent GB-2129747-A (GB)
Title: Bicycle lock
Inventor: SKYTTE OLE JORGEN
IPC: E05B71/00
Filed: 1983-04-27
Abstract: With a bicycle lock of the type having a blocking bar or a locking arm (10) mounted in a holding part (17) which is secured to the one leg (1) of the fork, the arm (10) can swing from a locked position, in which the arm is secured in an engagement part (18) secured to the opposite leg (2) of the fork, to a disengaged position. The locking arm (10) is mounted on a bush (8) which can turn and thus swing the locking arm for engagement with the engagement part (18)'s locking breech (16), wherein the latch (12) can engage with a groove (11) in the outer part of the locking arm (10). The lock can consist of a pair of metal canisters welded to each its fork leg and forming a housing for the remaining parts of the lock, and in the housing there can be provided a notch in which a ring of impenetrable material can be bedded. The actual locking arm (10) is free to rotate around its axis (20) in any position, which means that the arm can be turned without causing any damage, neither to the holding parts nor the locking parts. Moreover, since the lockingbreech (16) is completely enclosed within the locking block (13) in the engagement part (18), it is not possible to force or knock the locking arm out of the engagement part, in that the arm can be releaed only by an axial movement of the locking arm, and after the latch (12) has been turned out by means of the key (15). A possible housing will protect the internal parts of the lock, which can thus be made of moulding materials if desired, in that neither will the housing be capable of being sawn through, for example with a hack-saw.

Title: Cathode-Ray Tube Faceplate Contour
Inventor: D AMATO RALPH JAMES
IPC: H01J31/20
Filed: 1984-02-22
Abstract: A cathode-ray tube eg. a shadow mask colour tube, includes a rectangular faceplate which has an exterior surface having curvature along both the minor (Y-Y) and major (X-X) axes wherein at least in the center portion of the faceplate, the curvature along the minor axes is greater than the curvature along the major axis (as shown in Figure 6). In a preferred arrangement the curvature along the minor axis is at least 4/3 greater than the curvature along the major axis. The arrangement provides a substantially rectangular contour near the periphery of the faceplate lying in a plane P thus creating an illusion that a picture produced on the faceplate is flat. The faceplate may be associated with a shadow mask which similarly has greater curvature along its minor axis than along its major axis. Variations in the thickness of the faceplate are also discussed. <IMAGE>

Title: Inhibiting fungal or algal growth on buildings and other structures
Inventor: OLLEREARNSHAW IAN
IPC: E04D13/00
Filed: 1984-09-03
Abstract: Interior or exterior surfaces of a building or structure such as a greenhouse are protected from fungal or algal growth by the provision of sacrificial elements (15,24,30,35,42,101,102) of a material which exhibits a fungicide or algicidal action when wetted, for example with rain water, such that an aqueous solution of the fungicide or algicide washes over the surfaces when the elements are wetted in this way. The metal or metal-based compound (101) such as copper or tin may be surrounded by a water soluble coating of fungicidal or algicidal composition having a more vigorous action for use if the surfaces are already significantly affected by fungal or algal growth. The solubility of the outer coating (102) is much greater than that of the inner core (101) so that the outer coating is washed away in a relatively short space of time, whilst the core remains to provide a fungal or algal inhibiting effect preventing regrowth once the existing growth has been removed. <IMAGE>

Title: Digital map generator and display system
Inventor: BECKWITH PAUL B
IPC: G06T15/10
Filed: 1984-09-10
Abstract: In a digital information storage and read-out system, digital elevation and cultural terrain map data is read from a magnetic tape (10) in compressed form into an intermediate memory (20) which operates as a speed buffer. The data in the intermediate memory (20) is read out to a reconstruction processor (30) in which the compressed data is reconstructed and applied to a scene memory (35). A navigation computer (100) determines the instantaneous position of a vehicle with respect to the terrain and controls the reading of data into the scene memory (35) in blocks with the vehicle position occupying a center of scene location. To provide a heading up display of the terrain, the data in the scene memory is read out at an angle to its north-up storage orientation; interlocked scanning of pixel data in the scene memory improves resolution and enhances line display. The data read out of the scene memory controls the generation of video control signals to display elevation and cultural data as a moving map related to the vehicle position. <IMAGE>
