Title: An electrophotographic duplicating process
IPC: G03G9/09
Filed: 1963-03-01
Abstract: 987,767. Printing processes. AGFA A.G. March 1, 1963 [March 1, 1962], No. 8340/63. Heading B6C. [Also in Division G2] An electro photographic process for producing a plurality of prints from an electrostatic latent image comprises the steps of (I) forming an electrostatic or latent conductivity image on a photo-conductive insulating member, (II) depositing developer particles containing dye capable of subliming at a temperature of from 80‹ C. to 220‹ C. on the member in conformity with the image pattern, (III) partially transferring the dye to a second surface by heating the image to temperatures between 80 and 220‹ C. while in contact with the second surface to produce a print on the second surface due to part of the dye subliming while the remainder of the image is left as a residual image, (IV) separating the photoconductive member and the second surface and (VI) repeating steps (III) and (IV) with other second surfaces. The developer preferably consists of a powdered mixture of a sublimable dye and resin, the softening point of the resin being higher than the sublimation point of the dye. Dye bases of triphenylmethane series, dispersion dyes, smoke dye, benzine soluble dyes and oxidation dyes, capable of subliming with the range 80‹-220‹ C. may be used; specific examples of each are given. According to a modification, the developed image on the photoconductive member is transferred by electrostatic force to a transfer member and is transferred to a further surface by heating as in steps (III) and (IV).

[Also in Group XXVIII] A method of making corrugated reinforced hose comprises placing a helical reinforcing member over a tube of plastic material, placing a second layer of plastic material coated with a layer of fabric over the reinforcement, introducing this assembly into a corrugated mould so that the corrugations are aligned with the reinforcement, closing the ends of the assembly, introducing fluid under pressure into the assembly to cause it to conform to the shape of the mould and applying heat to fire together the tubes of plastic material and embed the reinforcement therein. A tube 10 is expanded on to a mandrel 11, over this is applied a helical reinforcing wire 12 which is secured to the tube 10 by tapes 13 to 16, the wire 12 between the tapes 14, 15 is removed, a second tube 16 coated with fabric 17 is placed over the wire 12 and the assembly is divided between the tapes 14, 15 to form two separate assemblies. More than two such assemblies may be formed on a mandrel. Plugs 19, 20 are inserted in an assembly which is placed in a mould 27, 28 with the wire 12 aligned with the. mould corrugations 30. Steam is then admitted through a pipe 25 in the plug 20 to inflate the assembly, force the plastic tube through the fabric 17 and to mould and cure the assembly to a corrugated reinforced hose. In a second embodiment the assembly is formed of alternate layers of two plastic tubes, reinforcing wire and finally fabric. The tubes and fabric may be built from sheets on the mandrel instead of being applied as tubes.

Abstract: 1381717 Orientating articles; vibration conveyers WHARTON ENGS (ELSTREE) Ltd 10 July 1972 [8 April 1971] 9043/71 Headings B8S and B8A Apparatus for separating elongate blocks from a random mass thereof and feeding them singly and in line to a desired location, comprises a support plate 1 which at one end 2 receives the mass of blocks and is inclined and/or vibrated to move the blocks towards the other end of the plate, an arrangement 3 being provided in the path of movement of the objects to separate single blocks from the mass and orientate them into longitudinal alignment with the length of the plate 1 as they are moved therealong. The arrangement 3 comprises a pair of arms 23, 24 mounted on an overhead structure 22 for pvioting movement parallel to the plate 1, the arms 23, 24 forming a V-shape converging in the direction of block travel and forming a gap at the apex of the V opening into a guide channel 4. The arms 23, 24 are pivotable between stops in a sequence whereby with both arms in a position having a minimum angle with the longitudinal centreline of the plate 1, the arm 24 pivots into its position of maximum angle and back to its position of minimum angle, whereafter the arm 23 which until that time has been dwelling, moves to its position of maximum angle and back again whilst the arm 24 dwells. This movement is controlled by a pair of wheels 28, 29 driven in the same direction by a pair of worms 30 on a common drive shaft 31, the wheels incorporating eccentrically positioned bosses 27 which reciprocate drive rods 25, 26 coupled between the arms 23, 24 and the bosses 27 through lost motion means generating the dwell periods of the arm movements. The leading block in the mass will engage the arms and be moved into a position lying alongside the arm having the said maximum angle at that time and as the arm moves back towards its said minimum angle, the leading end of the block passes through the apex gap and engages friction ribs in a tapered entry portion to the guide channel 4. When the said arm again moves towards its maximum angle, the block is pivoted about its engagement with the friction ribs by the apex end of the arm, to align the block with the channel 4 where the block moves on and the following block begins its orientation operation. The vibration of the plate 1 which is resiliently mounted is effected by a shaft 10 eccentrically mounted at one end to a motor driven shaft 8 and adjustably hinged at the other end to the plate 1. Each end of the plate 1 is adjustably spring loaded to support structure to control the amplitude of vibration of the plate.

Indicators actuated by pressure of f head of liquid. - In apparatus of the kind described in the parent Specification for indicating liquid level e.g. in a petrol tank, by injecting air through a pipe immersed in the liquid and measuring the pressure of the air, a submerged non-return valve is provided between the device for introducing air and the indicator. The tank 10 is connected by a pipe 18 to the reservoir 12 of a manometer 11. To keep the pipe 18 full of air, means are provided for automatically introducing air in small quantities by employing variations in pressure which occur in the intake or exhaust 22 of the engine. The pressure variations are transmitted through a pipe 23 to a casing 210, causing similar variations within a diaphragm box 20. Air is thus drawn in through a valve 24 and expelled through a submerged non-return valve 25. The pipe 18 may terminate in an enlargement 19, or in an extended horizontal portion. The Specification as open to inspection under Sect. 91 (3) (a) describes also a modification in which the valve 25 is outside the reservoir 12 and a pipe leads from it to a point below the liquid level in the reservoir 12. This subject-matter does not appear in the Specification as accepted.
