Title: Sensitisation of electrophotographic layers
IPC: G03G5/09
Filed: 1963-05-22
Abstract: 997,272. Electrophotographic materials. FARBENFABRIKEN BAYER A.G. May 22, 1963 [June 19, 1962], No. 20477/63. Heading H1K. Sensitization of an electrophotographic material is achieved by the uniform deposition on the photo-conductive layer of an aerosol of a sensitizing dye. The arosol may be formed from a solution of the dye or from solid dye particles. (The latter are subsequently dissolved on the surface of the photo-conductive layer by the application of a suitable solvent). The aerosol may be produced using a compressed air nozzle or an electrostatic atomizer. The degree of sensitization may be controlled by more or less concentrated deposition of the aerosol or by mixing different aerosols. In the example, the aerosol is produced from an n-butylbenzoate solution of bromocresol purple using a compressed air driven annular slit nozzle. The aerosol is charged by a corona discharge and deposited in the electric field of a plate condenser on to the electrophotographic material which is drawn at a constant speed through the condenser. The material consists of a paper supported layer of zinc oxide dispersed in a silicone resin. The treated material after being stored in the dark for 5 hours has a substantially uncharged dark resistance, is only very faintly coloured, and is sensitive to yellow and green light. Specification 994,645 is referred to.

Abstract: 805,542. Traverse-mechanism for spinning machines, T.M.M. (RESEARCH), Ltd. July 18, 1956 [July 18, 1955], No. 20736/55. Class 120(2) [Also in Group XXIX] In fluid - pressure operated traverse mechanism of the kinc wherein a reciprocatory member is periodically traversed by the operation of a fluid pressure operated motor having speed and reversal control means, the motor forms part of a servomechanism wherein the amplitude and speed of the movement transmitted to the reciprocatory member of the traverse mechanism by the output member of the motor are proportional to the amplitude and speed of the movements of the input member. In the arrangement shown, the ring rails 10 of a textile spinning machine are connected by straps 11 to a pulley 12 on the lifter shaft 13 which also carries a pulley 14 connected by a strap 15 with a vertically slidable cylinder 16 of -a hydraulic motor. The cylinder 16 slides on a fixed piston 17 and its movements are controlled by fluid under pressure being fed above and below the piston. The chamber below the piston is continuously fed with pressure fluid through passage 25 by pump 27 whilst the chamber above piston 17 can be connected with the pressure fluid supply or with the exhaust port 30 by movement of the valve 20. The land 203 of valve 20 has negative lap so as to permit the pressure in the top chamber to be adjusted such that a position of equilibrium of the cylinder is obtainable. Movement of the valve 20 is controlled by a control mechanism 33 of any appropriate type to give the desired package build and in operation any movement given to the valve 20 by the control mechanism 33 is followed by the cylinder which in turn imparts a corresponding movement to the lifter shaft 13 and thence to the ring rails 10. The rails 10 can be manually controlled for doffing. For this purpose a pressure release valve 35 is provided by means of which both cylinder chambers can be opened to the reservoir 26. In a second embodiment, the lower cylinder chamber is not continuously at full pressure and the control valve controls inlet and exhaust to and from the lower chamber alternatively with the top chamber, a position of equilibrium being obtained when the openings to both chambers are closed by the valve.
