Abstract: 1,271,589. Electron guns. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 19 Nov., 1970 [22 Nov., 1969], No. 55023/70. Heading H1D. An electron gun comprises a cathode having an emissive surface 15 on the end of a cylinder 14 of diameter D extending a distance 2D from a second cylinder 12 having a diameter H equal to 6D, a control grid having a cylindrical aperture portion 17 of diameter 6D and a conical aperture portion 19 extending at 45 degrees each extending axially a distance D, and an anode 21 spaced 1¢ D from the grid and having a cylindrical aperture 23 of diameter 4D. The anode may be extended by a cylinder 22 which defines a field-free space. The anode potential should be 4¢ times the negative grid potential, e.g. the anode may be at 10 volts and the grid at -2À2 volts. At an anode potential of 300 volts a very small cross-over may be obtained, as is desirable in an electron microscope. Electrons with a large transverse velocity may be removed by the provision at the cross-over point of a diaphragm with an aperture of diameter D. This also narrows the range of axial velocities of the selected electrons which is advantageous in a camera tube since it allows both a small spot size and a small beam inertia to be obtained. In the example given D is 100 microns.

Abstract: 1,165,539. Plastics foam laminate. SCHOLL MFG. CO. Ltd. 16 Dec., 1966 [20 Dec., 1965], No. 56483/66. Heading B5N. [Also in Division B2] A wear resistant foam structure comprises a layer of porous open celled polyurethane foam containing a thermoplasic impregnant, and a wear resistant overlying thermoplastic resin layer bonded to the impregnant by fusion and cooling of the layer and the impregnant jointly. The foam structure is made by impregnating the foam with a dispersion of a thermoplastic resin, applying to the impregnated foam a layer of a dispersion of a thermoplastic resin compatible with or the same as the resin of the impregnant, fusing the impregnant and the layer, and cooling the fused materials. The resin dispersions used may be aqueous emulsions or latices but are preferably plastisols containing a thermoplastic resin and a plasticizer and optionally mineral fillers, pigments, and stabilizers. Thermoplastic resins which may be used are vinyl chloride, vinyl acetate, vinylidene chloride, acrylic acid or acrylic ester polymers or copolymers, e.g. polyvinyl chloride, polyvinyl chloride plus polyvinyl chlorideacetate copolymer, and polymethyl methacrylate. The plasticizers used may be adipates, phthalates, phosphates or polymerized plasticizers, and many examples are given. As described the impregnant resin may be slightly gelled before contact with the plastisol layer, and the latter may be non-gelled, partly gelled, or fully gelled and partly fused before contact with the impregnated foam. In one method of making the products, a polyurethane foam strip 11, Fig. 1, is impregnated with plastisol by spreading, dipping, or spraying at an impregnation zone 13, the plastisol is worked into the pores of the foam by mechanical kneading, vacuum, pressure, or centrifugal force, at an homogenization zone 14, if desired the impregnant resin is partially gelled at a heating zone 16, and the impregnated foam strip is contacted with a layer 19 of plastisol carried on a belt 21 of release material. The foam strip and layer 19 pass between pressure rolls 23, 24 to a heating zone 26 where fusion, and optionally gelling, is effected, and then to a cooling zone 27. The layer 19 may be partly gelled or fully gelled and partly fused at a heating zone before contacting the strip 11. The laminates produced are flexible and may be used in vehicle seats, foot insoles, arm rests, or cushioning.

Title: Coating apparatus

Filed: 1970-11-30
Abstract: 1374424 Spraying car bodies CARRIER DRYSYS Ltd 29 Oct 1971 [30 Nov 1970] 56747/70 Heading B2L [Also in Division G1] Apparatus for spraying car bodies comprises a series of spray guns 15, 19 which move transversely to the direction of the conveyor 12 and television cameras 18, 21 which scan the passing car bodies to control the discharge of spray so that the spray guns only operate when the body is in the correct position to be sprayed by the gun as it passes. The camera 21 controls the horizontally moving spray gun and the camera 18 the vertically moving guns. The circuit relating to camera 18 and gun 15 is shown in Fig. 3. The gun on its complete movement produces 100 pulses by means of a coating unit digitising device 30 and these pulses are fed to a digital comparator 37. Horizontal synchronising pulses, one for each line of the frame, are fed from a 625 line T.V; camera along a line 33 and it is arranged that two hundred frames are transmitted during one complete movement of the gun. A divide by three unit 32 cuts the number of pulses into 104 groups of three pulses each and two divide by ten units 34, 35 are used to feed the obtained pulses to a digital comparator 37 where they are compared to the output of the spray gun movement. When one hundred groups of pulses have been counted a pulse along line 39 causes a flip flop 40 to close gate 41 and the last four groups of pulses are ignored. When the numbers of pulses from both sources are the same then a stroke pulse is sent along line 38 to a gate 43 and indicates that the camera and spray gun are in vertical synchronism. At the end of each frame a vertical synchronism pulse clears the units 32, 33, 35 and 40. Horizontal synchronising pulses are fed to a monostable pulse stretcher 44 and an adjustable monostable pulse generator 45 provides the timing and duration of a window pulse which is fed to a gate 47. This pulse allows only part of the video signal through so that a vertical strip is taken from the available picture format. High and low level contrast detectors 48, 49 produce an object pulse at gate 43 dependent upon the amount of contrast in the observed strip which signifies the presence of an object adjacent the gun. The gate 43 produces an action pulse which controls the supply of coating material to the gun through a flip flop switch 51. A line 56 direct from the digilising device 30 to the flip flop 51 resets the flip flop as the gun moves one micromental step so that the requirement of actuation of the spray device is assessed for each of the hundred steps in the complete movement of the gun but mechanical inertia in the system ensures that when the object is being coated the spraying is continuous whilst the object is in position. A zero volt detector is connected between the A.C. supply and the thyristor control 52 to ensure that switching occurs at voltage zeros.

The pipe is supported for rotation on rollers 13 and at each end of the pipe is a unit 15, 16, each associated with a respective working unit 17 for collecting spent abrasive from and for recharging its working unit. Each unit 15, 16 has a hopper 18 for the spent abrasive connected by an elevator 21 to a separator 23 and storage hopper 25. The ends of the pipe are received in seals 27 of the units 15, 16 and each working unit 17 is connected by a boom 33 to a car 35 or hydraulic boom for moving its unit 17 along the pipe. One unit 17 may start at one end of the pipe and travel towards the centre, and the other start at the centre and move towards the other end so that both units travel in the same direction. Each unit 17 consists of a number of circular plates 37 spaced apart by members 39 and forming compartments 41, 42, and the unit is supported by rollers 49 within the pipe to permit rotation of the pipe and longitudinal movement of the unit. The compartment 41 contains a pair of blasting wheels 29 rotated in opposite directions to throw abrasion particles downwardly into the pipe surface. The com partment 42 collects the used abrasive and contains an endless belt 53 having cleats 57 on its surface and driven over rollers 59 so as to be closely spaced adjacent the interior of the pipe and move at approximately the same speed as the pipe to carry the spent abrasive from the bottom of the pipe and deposit it in a trough 65. One of the rollers 59 is driven by a chain 63 from a motor 61 which is also connected by a chain 69 to a screw conveyer 67 in the trough 65 for carrying the collected abrasive to the blasting wheels. The rollers 59 for the belt 53 may be mounted on a pair of pivoted plates and a pneumatic cylinder pivots the plates to withdraw the belts from the pipe surfaces during retraction of the unit from the pipe. Further compartments 71, 72 store ballast or supplementary abrasive.
