Title: Method and apparatus for the electrostatic powder-coating of objects
IPC: B05D1/24
Filed: 1964-02-20
Abstract: A method of coating an object with electrically insulating powder comprises positioning the object alongside a fluidized bed of the powder, the bed containing ionizing means which are maintained at a high potential difference with respect to the object to be coated. The object to be coated may be conveyed between a plurality of horizontally disposed troughs containing fluidized beds of powder said troughs being spaced to cover substantially the whole surface area of the object (Fig. 1 not shown).  Alternatively one or more troughs may be mounted and arranged to reciprocate in a vertical direction to ensure uniform coverage of the surface of the object (Fig. 5 not shown).  In one embodiment a bathtub is inverted over a complementarily-shaped member which carries a plurality of horizontal troughs extending in loop form around its surface and coating is effected by fluidizing and electrostatically charing powder in the troughs (Figs. 3 and 4 not shown).  The ionizing means may comprise a series of spike members immersed in or protruding from the fluidized bed (Fig. 2 not shown) or may comprise a conducting or semiconducting grid or mesh upon which the fluidized bed is supported and through which fluidizing air is distributed (Fig. 6 not shown).  The object being coated is heated or otherwise treated to fuse the powder coating material into a coherent coating layer.

Heating by electricity.-An are for welding &c. purposes is formed between concentric electrodes and blown into a long flame by gases introduced between the electrodes. The outer electrode 2 is of tubular form and opens into a casing 3 into which the gas is led by an opening 6, the inner electrode 1 passing through insulating packing 4 in the casing so that it can be adjusted longitudinally or oscillated to strike the arc. The electrode 2 may be provided with an adjustable sleeve 8. The lead S' may be coiled round the electrode to rotate the arc. When polyphase current is used the electrode 2 is replaced by an insulating tube through the walls of which pass electrodes. The gas supplied to the arc may be such as to deposit carbon on the electrodes to reduce the consumption thereof or may be a reducing gas to prevent oxidation of the metals treated. Hydrocarbons or alcohol which may be mixed with oxygen or steam may be employed. Fig. 5 shows an arrangement for supplying a reducing vapour to the arc. The liquid to be vaporized passes from a tank 15 through a valve 17 and a retarding element 19 such as a plug of cotton wool or asbestos to a coil 18 between or outside the electrodes, the vapour escaping through nozzles 14. The outer electrode may be provided with a flared or bowl-shaped mouth 10 as shown in Fig. 4. The temperature of the arc may be varied by enclosing it in a space subjected to variable gas pressure in known manner.

Title: Carbon black pelleting process and apparatus
IPC: C09C1/58
Filed: 1958-03-06
Abstract: <PICT:0845041/III/1> <PICT:0845041/III/2> In a process for pelleting carbon black in which carbon is fed by a screw conveyer 80 to a pelleting drum 82 having an axial shaft 84 and radial rods 86, the output from the drum is fed to a weight belt 94 which sends a pneumatic signal to the motor driving the screw conveyer 80 to regulate the quantity of carbon being fed to the drum.  Water is fed to the drum at a fixed rate (40 to 55% weight for weight of the pellet flow) through a pipe 83 having a flow control meter 87. Alternatively, the weight belt may control the amount of water fed to the drum.  The pellets are densified in pug mills 96, 98, 100 and fed to a dryer 104.  The dry pellets are fed by an elevator 42 to a magnetic drum 46, which removes iron impurities, and are screened at 56, the product falling into a container 58 and oversized material into a vessel 68 from which it is blown back to the storage tank 34 through filters 24.  Separate filters 20 are used for the effluent gas from a cyclone separator 12, so that the filters 24 may be cleaned out without stopping production.  However, one of the filters may be common to both pipes 14 and 30.  The whole of the output may be returned to the tank 34 by operating valves 54, 66.  The ratio of water to carbon black is maintained so that the pellets incorporate 51% by weight of water.  The dried pellets have a moisture content below 1% and the density of the pellets is about 23 lbs. per cubic foot.

Abstract: 687,240. Photographic contact-printing and reflex-printing apparatus. GRINTEN, L. P. F. VAN DER, GRINTEN, P. A. W. VAN DER, and GRINTEN, K. J. J. VAN DER, (trading as CHEMISCHE FABRIEK, L. VAN DER GRINTEN. April 5, 1951 [April 15, 1950],No. 7930/51. Class 98 (ii). The apparatus comprises a transparent curved plate (i.e. a plate whose contour is traced out by a straight line moving parallel to itself) illuminated from its concave side, a flexible apron which can be laid close to the convex side of the curved plate so that it follows the contour of the plate and sandwiches between itself and the plate a sheet of light-sensitive material and an original sheet to be copied, the curved plate being adapted to be rolled between a resting position in which the plate and the apron are apart and the apron lies tangentially to the plate, and a working position in which the apron follows the contour of the plate, and one or more supporting members for the plate during such rolling movement, the construction being such that during such rolling movement only the curved margins of the plate or flanges secured thereto bear against the supporting member or members. As shown, Fig. 1, a tubular lamp 2, e.g. a high-pressure mercury vapour lamp, is supported by a framework 3 at the centre of a part-cylindrical, transparent sheet 1 which has flanges 4 resting on parallel spaced rails 5 so that the sheet can be rolled from left to right. An apron 9 is fixed at one end 8 to one edge of the sheet 1, and at the other end 10 to a rod held by projections 11 on bars joining rails 5, so that when the sheet is rolled to the right the apron 9 is rolled over its surface. Belts 20 are fixed to the edge 23 of sheet 1, lie over the surface of sheet on both sides of apron 9, and are connected by tension springs 21 to fixed projections 22. With the sheet 1 in its left-hand position, a light-sensitive sheet 13 and a transparent original 12 are laid in contact on the apron 9. When sheet 1 is rolled to the right, the light-sensitive sheet and original are pressed by apron 9 against sheet 1, and lamp 2 is energized to make the exposure. In a modification, flanges 4 are omitted and the edges of sheet 1 roll on the rails 5, which project above the rest of the base. In a further modification, the end of apron 9 is fixed to the end of a flat plate which rests against a fixed abutment. The end of this plate can be laid against an open book resting on an adjustable stand, so that a page of the book, in contact with a light-sensitive sheet, can be laid on the apron and pressed against sheet 1 for reflex copying. In this case, in order that sheet 1 may be enabled to press well down on the spine of the book, rails 5 may slope downward at the right-hand end, or the sheet 1 may be mounted eccentrically with respect to the flanges. Specification 650,097 is referred to.
