Title: Dockboard installation
Inventor: LOBLICK DERMONT FRANKLIN
IPC: B65G69/28
Filed: 1969-07-04
Abstract: 1294316 Dockboard installations D F LOBLICK 30 June 1970 [4 July 1969] 33904/69 Heading B8E A dockboard installation which may be mounted in a pit or on the surface of a loading bay, includes a dockboard 11 hinged at its rear end and to a base frame 12, movable relative thereto by a raising mechanism which comprises a lever 20 and a link 21 pivotally connected together at 22 and housing their remote ends pivotally connected to the dockboard 11 and frame 12 respectively, and an hydraulic ram housing its cylinder 26 pivoted at 25 coincidental with the link pivot to the frame, and its rod 27 pivoted at 29 to the lever 20 intermediate the ends thereof. A universal connection is provided between the lever 20 and dockboard 11 and a floating hinge between the dockboard and frame, to facilitate limited movement of the dockboard about its longitudinal axis. A lip 40 hinged to the front of the dockboard is movable between an operative position co-extensive with the top of the dashboard and an inoperative position in which it depends normally to the dockboard, this movement being controlled by a linkage system on the underside of the dockboard and operated by the lever 20 of the raising mechanism. During the first half of the dockboard raising motion, a link member 65 pivoted to the lever 20 is moved such that a pin thereon slides along a slot in a cranked member 61 pivoted to the dockboard, until the end of the slot is reached, whereafter the member 61 is rotated causing a rod 55 to be tensioned which rotates a crank member 49 causing links 42 to lift the lip 40 into its operative position. At this stage the member 49 has moved into an over-centre position which is sustained by the weight of the lip 40. The dockboard is then gravitationally lowered as fluid is bled out of the ram until the lip contacts the platform of a vehicle to be loaded or unloaded, whereupon the overcentre lock on the member 49 is released by the weight of the links 42 so that the lip will drop when the vehicle is driven away. A sliding joint between a bracket 60 on the cranked member 61, and the rod 55 permits this dropping of the lip which upon further lowering of the dockboard engages a support bracket and the dockboard is brought to rest in the horizontal position. If the dockboard has to move below the horizontal to engage a vehicle platform, the dockboard continues to move down when the lip drops as the vehicle is moved away, until a timed limit switch is operated thereby which causes energization of the fluid pump and the ram raises the dockboard joint above the horizontal, at which stage the pump is de-energized and the lip lowers onto its support bracket. An adjustable stop alongside the limit switch trips the overcenter lock on the lip in the event of the dockboard being lowered and the lip nut engaging a vehicle platform.

Title: Air formed adhesive bonded webs and method for forming such webs
IPC: D04H1/66
Filed: 1973-07-17
Abstract: 1439966 Non-woven fabrics; opening and lap forming apparatus KIMBERLY-CLARK CORP 17 July 1973 34101/73 Headings DIN and D1R An air laid web of randomly aligned wood fibres comprises an uncompacted unbonded continuum bonded by adhesive applied at discrete compacted areas spaced less than an average fibre length apart. Preferably the 'bonded areas are of lesser thickness than the unbonded areas. In the embodiment of Fig. 1 a pulp sheet 12 is devellicated by picker roll 22. Air from source 28 in combination with vacuum box 30 creates an air stream of uniform velocity in duct 24 to lay the fibres on foraminous moving belt 26. The width of duct 24 equals the height of the picker teeth on roll 22. The web has a basis wt. of 5-50 1bs/ 2880 ft<2>. An embossed heated transfer roll 32 having the same circumferential velocity as belt 26 prints the. web with an adhesive solution or dispersion. Contact with heater roll 32 for half a revolution drives off the carrier liquid from the web thus leaving solidified adhesive. Preferably roll 32 and belt 26 are of tetrafluoroethylene to facilitate release of the web. In Fig. 3 (not shown) the web (48) transfers from belt (50) to heated roll (54) at the nip between rolls (52, 54). The surface of roll (54) is smooth, liquid-borne adhesive being printed thereon by rubber-intaglio roll (56). The surface tension of the carrier liquid leads to the bonded areas being of lower thickness than the remaining areas. In Fig. 4, web 66 transfers from belt 64 to belt 70 at nip 68. Hot-melt adhesive is printed onto release coated belt 70 and absorbed by web 66 as it transfers to belt 70. Cooled roll 74 rotates slightly faster than belt 70 and acts to take up the web and cool its areas of spaced adhesive. Alternatively liquid-borne adhesive may be printed onto belt 70 and the liquid evaporated by heating roll 74. Roll 74 may have a release coating, alternatively a creping blade 96 is used to remove web 66. The wood fibres may be cedar or southern pine. The bond areas are arranged at a frequency or 10 to 40 bonds/in<2> and comprise 10 to 40% of the bond area. The adhesive may be starch, polyvinylacetate, vinylacetate/ethylene copolymer an acrylic polymer or polyvinyl chloride as an aqueous or non aqueous solution, an aqueous dispersion, plasticised with dioctyl phthalate or as a hot melt.

Title: Process and apparatus for coating a sheet of glass
IPC: B05B13/04
Filed: 1966-07-29
Abstract: 1,116,460. Coating apparatus; spray nozzles. COMPAGNIE DE SAINT-GOBAIN. 29 July. 1966 [29 July, 1965], No. 34243/66. Headings B2F and B2L. In depositing a coating of a substance on a continuously moving sheet of glass by spraying the atomised substance thereon, a continuous and uniform sheet of sprayed substances is formed by means of a plurality of spraying nozzles moved at a uniform speed transversely with respect to the direction of travel of the sheet of glass. In the embodiment shown, Fig. 4, a suitable member of regularly spaced nozzles P are fixed to an endless chain 1 driven by sprockets 3 and 4 so that each traverses across the sheet F to be coated. The spraying operation of the nozzles is restricted to the zone occupied by the sheet by automatic means e.g. cams co-operating with rollers to open and close controlling valves in a pneumatic system. As shown the sheets F are moved vertically and automatic means are provided to start and stop the motor driving the chain sprocket 3 as each sheet comes into or passes out of range of the nozzles. These may be upper and lower sets of nozzles attached to separate chains to spray the same or different coating materials on to the sheets F. In further embodiments the sheets are moved horizontally and the nozzles move either in a horizontal or vertical plane. Each nozzle (Fig. 6) has associated therewith an atomiser 18, a container 19 a valve 20 to control the supply of air for atomising and a valve 21 for controlling the opening and closing of the nozzle orifice. The liquid is sprayed through orifice 25 around which are grouped a number of air nozzles, 32, 33 through which atomising air is blown; the nozzles 32 serving in particular to exert outward suction on the jet of liquid while the nozzles 32 serve to control the shape of the jet. The valves 20, 21 are supplied with compressed air by pipes 42, 43 connected to collectors 44, 45 of flexible material and which form an integral part of the moving assembly. The collectors are connected to a general compressed air system by swivelling unions 44a, 45a; valves 47, 48 and pressure reducers 49, 50. In operation the valves 20, 21 are operated by rollers 36, 37 co-operating with cam surfaces 38, 39 and the latter or so formed that the action of valve 20 is slightly behind that of valve 21 so that atomisation air is supplied slightly prior to the opening of orifice 25 by needle valve 26.

Abstract: 296,933. Kingsmill, H. L., Dec. 20, 1927. Driving-arrangements.- In electric and other gear-driven locomotives, the gear and track wheels are coupled by a flexible linkwork system, wherein the gear-wheel is considerably eccentric to the track-wheel and may lie outside it. so that a high gear-ratio is possible without the use of a large-diameter gear and track wheels, and a large motor may be accommodated. The coupling, which allows vertical and lateral motions of the track-wheel, comprises three or more substantiallyborixontal coplanar links J connect. ing ball-ended studs G<2>, H<1> on the gear-wheel G and track-wheel H respectively, the length of the links being equal to the eccentricity of the wheels G, H and less than the distance between adjacent studs.

Title: Method of and means for recording line drawings on the screen of a cathode ray tube under computer control
IPC: G06G7/30
Filed: 1970-07-16
Abstract: 1327419 Cathode-ray tube displays DRING RUDOLF HELL GmbH 16 July 1970 [16 July 1969] 34632/70 Heading H4T In an arrangement for achieving uniform brightness in the tracing of line drawings on the screen of a cathode-ray display tube the lines are approximated by a plurality of straight lines of different lengths (Fig. 1) the co-ordinates of which are supplied by a computer as respective #x, #y, voltages which control respective deflection generators producing sawtooth waves of constant duration but with slopes proportional to #x and #y respectively, the #x and #y quantities being squared, added together and the square root of the sum extracted to provide a quantity for intensity control of the tube beam. Alternatively the latter quantity is formed by multiplying the sum and difference of #x, #y by constant respective factors and adding the resultant quantities. Fig. 2 shows one embodiment in which the sawtooth generators 63, 64 are controlled directly by the co-ordinate values #x, #y during equal intervals determined by a pulse generator 65 whilst the intensity of the tube beam is controlled as a function of deflection velocity by squaring #x, #y in respective operational amplifiers 53, 54, summing the outputs of the latter in adder 57 and employing the summed output to control an operational amplifier 59 producing the function ##x<SP>2</SP> + #y<SP>2</SP>. The latter quantity is then supplied to the intensity control means of the tube 22 via a correction circuit 61 which predistorts the control function voltage to compensate for the non-linear relationship between it and the light intensity produced by the tube. In a modification of the latter embodiment which avoids errors, particularly at low deflection velocities, in electronically squaring and subsequently forming the square-root, the function for controlling the beam intensity is produced by forming the sum and forming the difference of the co-ordinate values #x, #y and then adding such sum and difference to form the input to the correction circuit 61 (Figs. 3 and 4, not shown). In a further modification, the input to the correction circuit comprises, in addition to the sum and difference as in the last modification, further inputs derived by subtracing from the difference input predetermined fractions of the sum input. (Figs. 5 and 16, not shown.)
