Title: Process for graining the surface of support material for planographic printing plates
IPC: B24C3/12
Filed: 1970-12-11
Abstract: 1277567 Spray producers KALLE AG 11 Dec 1970 [15 Dec 1969] 59059/70 Heading B2F [Also in Division B3] A process for graining the surface of a support material M for planographic printing plates comprises causing the material in strip form to travel past a jet 9 of graining means suspended in a liquid, the jet impinging on the strip over its entire width. The material, such as aluminium or plastics, is guided by rollers 1, 3 over a drum 2 disposed in an opening in the upper wall 5 of a chamber 7 containing a suspension S, such as iron powder, corundum, aluminium oxide or the like in water. A slot die 8 is disposed beneath the drum and has a slot extending parallel to the drum axis for the centre length of the drums. The die has two chambers 10, 11. Chamber 11 is connected to a pressure line 16 of a liquid pump 12 which also has a suction line 13 and pressure line 14 for circulating the suspension S, and chamber 10 is connected by a line 18 to a compressed air source. The spray jet impinges over the entire width of the strip, the graining means suspension falling back into the chamber 7 along paths T and the line being drawn along paths R past baffles 21, 22 and into separators 23 by fans 25. The fans also supply air to air knives 28 which clean the material before and after graining by the suspension. The slot die acts as a mixing nozzle for the suspension and air supplied to the chambers 10, 11, the mixing being effected by a whirling inside (31, Fig. 2, not shown). In another embodiment, air is supplied to a chamber (10, Fig. 3, not shown) in an inverted funneltype chamber (35) immersed in the suspension and entrains the suspension for impingement on the material. The suspension may contain a dissolved or suspended degreasing agent and a dissolved adhesion improving agent. In a further embodiment, the jet is centrifuged by a rotating body.

Title: Circuit arrangement for controlling the supply of power to a load
IPC: H02M3/155
Filed: 1972-12-29
Abstract: 1373740 Transistor switching circuits HONEYWELL INFORMATION SYSTEMS ITALIA SpA 29 Dec 1972 [29 Dec 1971] 60168/72 Heading H3T [Also in Division G3] A load is supplied from an unregulated source by way of a series transistor, the base-emitter junction of which is connected across one winding of a pulse transformer. Two other windings are connected in respective branches of a current switching circuit, one of these windings turning on the series transistor and the other, in circuit with a diode, operating to remove minority charge stored on the transistor base. As shown, a constant frequency regulated chopper circuit comprises a load 3 connected to a source Vp through a filter network 2 and a series transistor 1. The conduction of the transistor is controlled by pulse transformer 4, the inputs of which are connected through respective transistors 10, 11 and a common emitter resistor 14 to an auxiliary supply +V. In operation, when a reference voltage V 2  exceeds a control voltage V i , transistor 10 conducts and transistor 11 is off, so that current flows in windings 8, 5 and transistor 1 turns on. Since diode 12 is blocked, as current flows in winding 9. If the control voltage V i  increases, transistor 10 blocks, and windings 5, 9 ensure the removal of charge stored on the base of transistor 1. The e.m.f. induced in winding 9 causes current to flow through diode 12 and transistor 11, diode 13 being reverse biased, so that reverse base current flows from transistor 1. Subsequently, diode 12 blocks, and the collector current of transistor 11 flows through diode 13 to supply -V until transistor 10 is again turned on. A zener diode voltage limiting circuit 6, 7 may be connected across either winding 5 or winding 8.
