Filed: 1971-04-19
Abstract: 1335130 Matrix displays SCIENCE ASSOCIATES Inc 19 April 1971 [13 April 1970] 26532/71 Heading G5C A display panel has a plurality of light passages extending through it and internal cavities intersecting the passages, a closure member in each cavity which moves between positions in and out of the passage and a releasable latch holding each member in one of the positions. A display assembly 50 mounted in a housing comprises a plurality of horizontal panels (62), Fig. 1 (not shown), each comprising sections 90 connected together by shafts 63 to form an endless chain. Rollers at each end of the shafts 63 engage sprockets 56 of a drive-shaft 53 and are guided by vertical channels of the housing and by guide surfaces 75 extending between the channels. An array of fluorescent lamps in front of a reflector is mounted within the belt; the edges of adjacent sections overlap to prevent light passing between them. Each panel section comprises inner and outer members 91, 95 containing light passages formed of conical apertures 116, 117 and recesses 118 containing opaque discs 125 of non-magnetic material, e.g. brass or plastics material. The apertures are covered by translucent diffusing plates (97), 97a. Each disc is held in the obscuring up position by a latch pin 127 in a groove which slopes down towards the recess 118. The recesses 118 extend diagonally in the vertical plane so that each disc rests on the side of the recess as well as on the pin to reduce friction between the disc and pin. As panels travel downwards through the non-viewed path, the pins fall from the discs allowing the discs to fall into their obscuring positions. The pins move to support discs as the panels turn at D into the viewing position. A pattern is produced by activating electromagnets (130), Fig. 5 (not shown), which withdraw selected pins allowing the associated discs to fall into their non-obscuring positions. The operation of the electromagnets is synchronized with the position of a row of pins using a photocathode to sense light from reflective strips 134 on the panel sections. Data is received in series-digital form and stored. When sufficient data is received to fill a row the belt is moved sufficiently to carry one row of panels past the electromagnets. In a modification the bottom parts of the recesses may intersect the light passages.

Filed: 1932-09-24
Abstract: 401,858. Door checks ; hinges. TONKS, W. H., 201, Moseley Street, Birmingham, Sept. 24, 1932, No. 26600. [Classes 65 (i) and 65 (ii).] A hinge incorporating a fluid check device comprises a cylindrical barrel forming one of the knuckle parts of the hinge, a hollow piston slidable axially in the barrel, a hollow axial helical stem secured at one end to one of the other knuckle parts and arranged to engage one end of the piston, and an adjusting rod passing through the helical stem and adapted to control the flow of fluid through the end of the piston opposite to that engaged by the helical stem. The barrel portion c, carried on one of the hinge plates, has its ends closed by screwed plugs hand covered by knuckle parts d on the other hinge plate. The lower plug h bears either on a stub pin s screwed in the lower knuckle d, or, in a modification, on a thrust ball which replaces the pin. A hollow stem i is fixed in the upper knuckle d, being secured against rotation therein by a screw key t, and is formed with helical grooves constituting a quick-pitch screw thread engaging the upper part j of a hollow piston e which thus works as a nut on the stem i ; the piston e is prevented from rotation in the barrel c by keys f, so that relative movement of the hinge members causes sliding of the piston. A rod k, screwed and adjustable in the hollow stem i and provided with a finger-knob and lock-nut at its upper end, has a hollow lower part engaging over a tapered stem l which projects through a bore in the lower end of the piston and more or less closes the opening at the end of the rod k according to the vertical position of this rod. The rod k has an aperture m in its side, and the piston has apertures p in its walls and a ball valve q in its lower end. Fluid passes freely through the ball valve q during the upward movement of the piston, but this is closed in the downward movement and fluid can then only pass freely through the piston while the latter is above the lower edge of the aperture m, the motion being checked thereafter by passage of the fluid through the opening at the end of the rod k, restricted by the stem i ; the rod k is usually arranged to extend within the bore in the lower end of the piston, as shown, in the lowest portion of the latter, but it may be raised so that the piston passes clear of it to give an unchecked final closing movement.

Abstract: 759,170. Valve closure members. CLYDE CRANE & BOOTH, Ltd. Sept. 28, 1954 [Sept. 29, 1953], No. 26715/53. Class 135. An hydraulic valve is provided with back pressure chambers such that the closure member is held closed by fluid pressure irrespective of the direction in which the pressure acts. In one embodiment the closure member 23 coacts with a seating 8 in a ported sleeve 2 and has a hollow, upper extension to receive a plunger 21. An inlet 12 communicates through a port 11 with a chamber 5 from which pres-. sure fluid has access through passages 25, 26 to a chamber 24 in which the pressure acts to close the valve over a larger area than that acting in the chamber 5 on the conical part 9 of the closure member. Back pressure from the outlet 15, which is effective in a chamber 4, acts downwardly on the closure member on annular areas 27, 28 greater than the area of the conical part of the closure member which is subject to the pressure in the chamber 4. The closure member is loaded by a light closing spring 29 against which it is operated, e.g. mechanically, electrically or hydraulically, by a tappet 30. In a modification the plunger 21 is hollow and the upper end of the closure member slides in it.

Abstract: 1,240,161. Washing machines. SEVERARD Ltd. 6 Oct., 1969 [6 July, 1968], No. 26953/68. Heading D1A. [Also in Divisions A4 and F4] In a base fitment adapted to support a domestic appliance having a drawer, a roller for engaging the floor surface to permit movement of the appliance is rendered operative or inoperative by control means arranged so that the drawer of the appliance must be at least partly open before the roller can be made operative, and so that the drawer cannot be completely closed when the roller is operative. The control means may have a handle projecting into a bottomless drawer space when the roller is operable, and may comprise a brake acting on the roller. The roller may be mounted on a screw jack arrangement so that the handle is raised as the roller is lowered relative to the fitment. In the embodiment shown a spring loaded catch 15 engages a groove 7 the operating handle 76 of a screw carrying the roller so that the roller cannot be lowered without releasing the catch 15. When the catch is released, the spring carries it above the lower surface A-B of the drawer compartment to obstruct the closing of the drawer. The handle 6 is only accessible when the drawer is open. In a modification, a pivoted cranked lever on the operating handle engages part of the fitment to prevent lowering of the roller in one position, and, in a position when the roller can be lowered, projects into the drawer compartment. An appliance haying a base fitting according to the invention may also have an anti-tilt device Fig. 7 comprising a bar 108 extending across the back of the appliance and a bracket 110 adapted to be secured to the floor or a wall and having an arm 111 projecting forwardly over the bar 108. The bar may fit in place of the normal feet of an appliance, or may fit over the attachment screws of the feet or rollers. The bar may carry rollers co-axial with it, or may be cranked so that its mid part is co-axial with existing rollers. It may be adjustable in length.
