The imaging member is developed after charging and image-wise exposure in a two-step process whereby in a first step a solvent for said soluble layer is used whereby the migration material forms an image lying on the particulate carbon layer and in the second step the conductive layer is dissolved away together with a portion of the particulate carbon layer to give respectively a positive or negative image according to whether the solvent for the conductive layer 12 simultaneously dissolves the migration material 15 and the carbon layer 13 thereunder (Fig. 5, not shown) or the carbon layer not covered by the migration material (Fig. 6, not shown). An insoluble support 11 of glass, paper or plastics has a conductive film 12 of Al, Sn O 2 , Sn, In, Cu 2 I 2 or Cu 2 S and an overlying film 13 of graphite, charcoal, coke, carbon black, lamp black or activated carbon which may be formed by coating with a colloidal carbon solution and drying, or dusting or cascading carbon particles on the film. The solvent softenable layer 14 is preferably a hydrogenated glycerol rosin ester but many other plastics materials and sucrose benzoate are specified. Particles 15 of vitreous selenium are deposited on the layer 14 by vapour phase deposition. Other suitable photo-conductors are specified. These may be in the form of a continuous or semi-continuous layer which is capable of breaking up during the first development stage. The particles may also be applied to the heat or solvent softened layer 14 by dusting or coating with a slurry. In other embodiments, the particles may be sandwiched between two plastics layers or dispersed in the layer 14.

Title: Bending-roll unit for continuous-casting machine
IPC: B22D11/12
Filed: 1972-11-27
Abstract: A bending-roll unit for continuous-casting machines, where the unit directly follows a guide-roll rack and precedes a curved roll rack. The unit embodies a combination of driven rolls and idlers arranged in opposed pairs. One of the driven rolls is a fulcrum roll which defines the tangent line where a casting first acquires a curvature. Other driven rolls above and below the fulcrum roll sustain the reaction forces. These driven rolls also supply the initial tractive force which propels the casting and thus eliminate the need for separate driven pinch rolls usually located above the bending rolls. Floating idlers confine the casting against bulging. The unit may be used with either a flexible starter bar or slightly modified with a rigid bar.

Title: Dry coke quenching process
IPC: C10G9/30
Filed: 1978-03-04
Abstract: A dry coke quenching process comprises the steps of preheating coke from a coke oven to a temperature of not lower than 1200 DEG C. by way of burning over its layer a combustible gas mixed with heated air, cooling the coke first to a temperature of not lower than 700 DEG C. with a mixture of hydrocarbons and water vapor, and then with an inert gas to a temperature of from 200 DEG to 250 DEG C.

Title: A system for moulding metal bodies.
IPC: B22C/
Filed: 1978-07-14
Abstract: The object of this invention is to eliminate the operations of moving the bodies to be stamped from one point to another, as they move themselves from one place to another, by sliding. Once out of the crucible and its moulding achieved the temperature of the body which moves itself does not drop, it is maintained, the temperature is maintained and increased due to the route along which it travels being inside a furnace chamber, which causes the weakened points of those exiting or entering together with the rolling elements used on the body to be moulded, to melt at the weakest point and thus to separate from the body from which they project or into which they penetrate, and the body therefore falls inside the moulding instrument which on closing receives the impact necessary for the final moulding through stamping.
