Title: Multicolour display for the visual-aesthetic portrayal of electric signals method and apparatus for connecting two or more wires
IPC: A63J17/00
Filed: 1973-08-22
Abstract: 1450453 Coloured display KEW 1NC 22 Aug 1973 [13 July 1973] 39697/73 Heading A6M [Also in Divisions H1 and H4] A coloured display is produced using a colour television tube, by applying a pair of random signals-e.g. derived from an audio source using a pair of stereophonic channelsto the deflection coils of the tube, which coils are displaced from their normal position on the tube neck, such that the or each beam, during deflection, impinges upon phosphor segments of all three colours (see Div. H1). The arrangement produces, for a three gun tube, three parallel but differently multicoloured traces on the screen of the tube; two or one traces only may be produced by biassing one or two of the three guns to cut-off. The tube may be operated with a 50% anode nipple whereby, for suitable biassing of the guns, the traces may be arranged to fade to zero in the nipple valleys, to give a dashed-line effect (see Div. H4). Additionally, an a.c. signal may be applied to the degaussing coil around the tube screen, to ensure multicolouration of the display even for very weak signals producing deflection only over the central region of the screen.

Abstract: 1524964 Furnace linings IMPERIAL CHEMICAL INDUSTRIES Ltd 21 Aug 1975 [12 Sept 1974] 39823/74 Heading F4B A furnace lining consists of a number of panels each comprising an open-backed box 2 of refractory-bonded inorganic fibre having lugs 3 on the open side to retain the panel by passing through apertures in a furnace wall and being held, e.g. by wedges. The lugs may be integral, or attached to the wall of the panel. The inorganic fibre may be of aluminosilicate, calcium silicate, silica, glass, asbestos or one or more polycrystalline refractory metal oxides, e.g. polycrystalline alumina, alumina/silica or zirconia. The bonding agent may be an inorganic oxide, e.g. silica alumina zirconia or a mixture of these. Or it may be a substance producing such an oxide when heated. This may be applied as a sol, for example a boehmite sol for panels of alumina fibre and an alumina or zirconia sol for panels of zirconia fibre. The box may be made as in paper making by being drawn out of an aqueous dispersion and shaped by vacuum forming. The box is filled with two layers of insulating material, e.g. a layer of non-bonded fibre mass of the same fibre as the box. The other layer or layers may be of less refractory fibre. The box may be closed to retain the filling by an inorganic fibre sheet or a non-refractory sheet which burns off in use. The box may be wound round the periphery by zirconia fibre cords 6 received in grooves 7. The gaps between adjacent panels are also filled with refractory fibre to prevent loss of heat.

Filed: 1972-08-29
Abstract: 1345990 Grinding; filing SHIONOGI & CO Ltd 29 Aug 1972 [29 March 1972] 40094/72 Addition to 1268477 Headings B3D and B3L [Also in Divisions A5 and B5] An apparatus for chamfering tablets comprises a frame F supporting a rotatable disc 1 having a grinding or abrading surface, and a guiding member 5 for the tablets consisting of two working segments 51, 53 which have a plurality of grooved channels open towards the surface and intersecting the direction of movement of the surface at an angle other than a right angle, the segments being one at each end of an intermediate segment 52 having grooved channels for passing the tablets from one segment 51 to the other 53, the channels in the first segment guiding the tablets so that one of their sharp edges are abraded by the surface, the channels in the intermediate section being shaped to receive the tablets from the first segment and pass then to the second segment the channels of which guide the tablets so that the second of the sharp edges are abraded by the surface. The frame F supports the disc to rotate about an inclined axis, the surface of the disc being abrasive or in the form of a file. The guiding member 5 is held slightly spaced above the abrading surface and consists of a body having the three segment 51, 52, 53 and five grooved channels 61-65. The channels are equidistantly spaced and in the working segments 51, 53 have their centre lines spirally shaped so that at every point along it each line makes an angle of 40 degrees with the tangents of every circle constituting the disc. The tablets, which may be formed in a tableting press and have a circular shape with convex ends producing two circular shape edges, are fed to the inlets 71-75 of the grooved channels in the first working segment 51 through passages 91-95 in a tablet aligning means 9. The grooved channels in the first segment guide the tablets in an inclined position as they move along the channels under the force of gravity and by engagement with the abrading surface of the disc so that one of the sharp edges is removed. The inclination of the tablets may be varied in their passage through the segment so that the edge is rounded. The channels in the intermediate segment reverse the inclination of the tablets so that the other sharp edge is abraded as the tablets move along the channels in the second working segment 53.

Title: Improvements in nailing machines
IPC: B27F7/09
Filed: 1957-12-27
Abstract: 838,330. Nailing machines. WYLIE & CO. Ltd., M., and WYLIE, M. J. G. Dec. 27, 1957, No. 40196/57. Class 89(3) In a nailing machine wherein nails are fed to a series of hammer boxes 3 carrying hammers 3a which drive the nails into a workpiece, the hammer boxes 3 is associated with a series of drills 12 as a unit which is movable so that the drills 12 and hammer boxes 3 can be brought successively into a position directly over the points in to which the nails are to be driven, whereby the drills drill a series of holes and the nails are thereafter driven into the drilled holes. In the embodiment described, the hammer boxes 3 and a vertically slidable slide 10 which carries the drills 12 are both carried by a horizontally slidable slide 8 which is carried by a frame 6 which can be lowered under the the influence of fluid pressure piston and cylinder assemblies 7 to clamp a workpiece to a table 4. The slides 8 and 10 respectively are operated by fluid pressure piston and cylinder assemblies 9 and 11. At the commencement of a cycle of operations the drills 12 are directly above the points where the nails are to be inserted. A manual or pedal operated fluid pressure control is actuated to cause safety stops 13 to be withdrawn from the path of the frame 6. The stops 13 in turn trip valves which control the supply of pressure fluid to the piston and cylinder assemblies 9, cause the frame 6 to be lowered to clamp the workpiece on to the table 4. When lowered, the frame 6 automatically initiates operation of the piston and cylinder assembly 11 whereby the slide 10 is lowered and then raised and also causes a supply of compressed air to be connected to the pneumatic drills 12 during movement of the slide 10 so that holes are drilled in the workpiece. When the slide 10 is returned to its upper position a valve is operated to admit pressure fluid to the piston and cylinder assemblies 9 to move the slide 8 into a position wherein the nail boxes are above the drilled holes. A valve tripped by the horizontal slide 8 at the end of its movement, then causes a hammer slide 5 to be coupled to a power driven rotary member to drive the nails into the drilled holes. A trip valve operated by the hammer slide then initiates a series of valve operations whereby the anoaratus is reset to its starting conditions ready for the next cycle of operations.

Abstract: 1302820 Rotary indicator; visible signalling apparatus MINIATURE ELECTRONIC COMPONENTS CORP 31 Aug 1971 [21 Sept 1970] 40561/71 Headings G5C and G4F [Also in Division H1] In a two-state electromagnetic indicator comprising a permanent magnet, rotatable between two limit positions determined by mechanical stops and carrying a disc which presents a different display in each limit posi. tion, the stops may be magnetized by an electromagnet to deflect the rotary magnet from one position to the other position, the "set" position, and the stops may be rotated into engagement with permanent magnets to magnetize them in the opposite sense to repel the rotary magnet to its original or "reset" position. In the embodiment a threaded case 2 contains two electromagnets comprising coils 20 wound on cores 22, 24 which are joined by a soft iron disc at one end. Two permanent magnets 56, 58 are positioned circumferentially between and parallel to the cores 22, 24. A cap 12 abuts flange 6 of case 2 and is rotatably retained by locking-ring 132 on a portion 86 extending through sleeve 40 of the case 2. A helical spring 136 located in slots in portion 44 of the case and in the cap portion 86 rotationally biases the cap. A disc 75 and a transverse permanent magnet 104 are attached to hub 100 of a shaft 92 rotatable in cap portion 86, and two stops 106, 108 are mounted on pins 110 fixed through cap portion 84. In the original or "reset" position the rotary magnet 104 rests as shown in solid lines, Fig. 9, against ends 118 of stops 106, 108 and the flats 114 of pins 110 of the stops engage the flats 64 on the ends of cores 22, 24. When the coils are connected in series to a D.C. source to make stop 108 a N pole and stop 106 an S pole, the rotary magnet 104 is repelled from the solid to the dotted line position where it will remain after disconnection of the supply since flux loops extend through the stops, the cores 22, 24 and disc 26. The device is reset by turning cap 12 anticlockwise as shown, until stops 106, 108 contact permanent magnets 56, 58 and repel the magnet 104 which rotates into contact with the other ends of the stops. On release of the cap 12, spring 136 returns it to its original position and the device is ready for re-use. A screen 128 limits the effect of permanent magnets 56, 58 when the electromagnets are moving the rotary magnet 104. The disc 75 may have three equally spaced white sectors separated by black sectors and be viewed through window 74 having three equally spaced sectors rendered opaque by a black coating so that in the "set" position the white sectors show but in the reset position the display is entirely black.

Abstract: 880,238. Protective cut-out arrangements. GERRARD, M. C. Dec. 15, 1959 [Dec. 16, 1958; July 24, 1959], Nos. 40632/58 and 25434/59. Class 38 (5). [Also in Group XL (c)] A protective arrangement comprises a trigger device T, e.g. a cold cathode tube or a transistor, connected in one arm of a bridge circuit B of which one diagonal is connected across the supply circuit to the protected apparatus and the other diagonal includes the coil A of a relay having contacts in the supply circuit, the trigger electrode of the device T being connected to a point in a potential divider P connected between the live supply conductor L and an earth loop for the apparatus. Under normal conditions the device T is non-conducting, the bridge is unbalanced and relay A is energized. If the earth loop is not continuous or if the neutral earth is unsatisfactory the lower end of the potentiometer ceases to be at earth potential so that the voltage at the trigger electrode rises. The device T conducts so balancing the bridge and causing the relay A to open. To provide protection in the event of an earth fault, a differential transformer may have its primary windings in the supply conductors and its secondary winding in the earth loop or in the lower part of the potentiometer P or in the connection to the trigger electrode. Alternatively, a transformer may have its primary winding connected in the earth line E2 and its secondary winding in the connection to the trigger electrode of the device T. When the supply is alternating current, a rectifier G is used and voltage stabilization is provided by one or more non-linear resistors M or neon tubes (not shown). A rest push-button switch may be connected across the device T and a test push-button may be arranged in the earth loop, Fig. 2 (not shown). A resistor R and change-over contacts H of the relay may be provided to ensure that the initial closing of the relay is dependent on the supply earth being satisfactory.

[Also in Group XXVIII] In a method of winding a filament under controlled tension the filament 21 is associated with the shaft 26 of an electric motor and the rotating mandrel 27 on to which the filament is wound, is rotated in such a way that the output shaft 26 is rotated in a direction opposite to the direction in which it is urged by its energizing current, the tension in the filament being controlled by the power input to the motor. As shown the filament is pressed by a roller 25 against a roller 24 fixed to the output shaft 26. In other forms the connection between the filament and the shaft is obtained by wrapping the filament about a roller on the shaft through such an angle that the frictional contact prevents slippage. In a further form the spool from which the filament is drawn is mounted directly on the backwardly biased motor shaft. Suitable electric motors are A.C. multi-phase motors or induction motors.

Title: Colour television
IPC: H04N9/16
Filed: 1962-10-29
Abstract: 1,026,865. Colour television. INTERNATIONAL POLAROID CORPORATION. Oct. 29, 1962 [Nov. 2, 1961], No. 40814/62. Heading H4F. [Also in Division H1] A colour television receiver operates according to the "red-white" principle of colour reproduction. The receiver responds to signals representing red and green components of an original image and employs a cathode-ray tube having a screen formed with two phosphors, one of which produces red light in response to electron impingement of comparatively low energy and the other of which produces minus red (i.e. blue-green) light in response to electron impingement of comparatively high energy, the arrangement being such that only the red phosphor is excited in response to the " red " signal but both phosphors are excited in response to the " green " signal so as to produce white light. In a first embodiment of the invention, Fig. 2, the cathode-ray tube face plate 40a bears superposed minus-red and red phosphors 41a, 42a, and an assembly of closelyspaced but separate aluminium strips 43a. There are approximately 500 strips with a width equal to the spacing and comparable to the size of a focused electron beam. The tube is operated at an anode potential such that the electron energy is sufficient to penetrate and stimulate emission from both phosphors. However, when the beam impinges a metallic strip the energy is reduced to a value such that only the red phosphor is effectively excited. The tube may utilize a single electron gun which is modulated by the " red and green " signals alternately at dot, line or frame rate and the beam is scanned over the tube screen so as to impinge the aluminium strips when red light is to be produced in response to the " red " signal and to impinge between the aluminium strips when white light is to be produced in response to the " green " signal. For operation at the dot rate the aluminium strips are disposed transverse the raster line scan direction. In an alternative arrangement the tube utilizes two electron guns which are controlled separately by the " red " and " green " signals, the electron beams being arranged to be focused at points which are spaced apart so that common scanning control causes one beam to transverse the aluminium strips and the other to traverse the intervening spaces. In a second embodiment, Fig. 4 (not shown), the two phosphors are formed as normal continuous layers. The tube is provided with two guns which are arranged at suitable different cathode potentials with respect to the final anode so as to cause excitation respectively of one and both phosphors. Alternatively a single gun is provided, Fig. 5 (not shown), which is modulated alternately by the two colour signals whilst the anode potential is switched between values which cause energization of one and two phosphors. The phosphors layers are separated by a gold layer 77 which is thin enough to be light transmitting filter. Layers 76 may produce minus red light or white light the minus red component of which is filtered by layers 77.
