Title: Improvements relating to image reproduction processes
IPC: G03F7/032
Filed: 1965-10-27
Abstract: 1,099,489. Photographic process. E. I. DU PONT DE NEMOURS & CO. Oct. 27, 1965 [Oct.28, 1964], No.45542/65. Headings G2C and G2M. A laminate of two transparent or translucent supports having a layer of a photo-polymerizable monomer between them, is imagewise exposed from one side and uniformly exposed from the other, and the supports separated to obtain a positive image on one support and a negative image on the other. The relative intensities of the exposures are such that the degree of adhesion caused by the overall exposure between the surface through which that exposure is made and the adjacent surface of the photo-polymerizable layer is less than that between the other support and the adjacent surface of the photo-polymerizable stratum in the most highly exposed areas. The supports may have matt surfaces. Suitable supports and photo-polymerizable materials are described in Specification 1, 090, 663. In an example a laminate of a transparent polyethylene terphthalate film, a layer of photo-polymerizable monomer (a mixture of the triacrylate of polyethyleneoxy trimethylol propane, 9, 10-phenanthrenequinone, polymethyl methacrylate, methoxy polyethylene glycol hydrogen succinate) and a translucent film, is imagewise exposed to a negative through the translucent film, uniformally exposed through the transparent film, and torn apart; the positive image on the translucent film is treated with aqueous SiO 2 , Zr O Cl 2  and glycerol to form an offset printing master.

Abstract: 1,193,970. Three roll bending machine. E. HORDON. 12 Jan., 1968 [14 Oct., 1966], No. 45905/66. Heading B3E. A three roll bending machine has the rollers supported at their ends by bearings mounted in standards, the lower rollers being arranged to be driven from one end and at their other ends all the rollers having their axles extending through the bearings and arranged to have detachably secured on the extensions a set of formers which are located on the outer side of the adjacent standard, the bearing and the bearing support for the axle of the upper roller being arranged to open to permit removal of rolled sheet from between the rollers. The lower rollers 1 and 2 are mounted on axles 3 and 4 which project through the standard 5 and are of reduced diameter at their projecting ends to receive formers 19. The formers are keyed to the lower axles and that on the upper axle is freely rotatable. The upper roller is held against upward movement by a half-bearing 8 the position of which is adjusted by a screw 12. A stirrup 17 passes under the axle and holds it against the bearing. The upper bearing of the standard 5 is slidable in the cap 13 which is connected to the lower part of the standard by a pivot pin 15 and a removable locking pin 16. Removal of the pin 16 and stirrup 17 allows the cap to be swung open to enable a rolled workpiece P to be removed axially from between the rollers.

Filed: 1971-10-11
Abstract: 1368757 Amplifiers HONEYWELL INFORMATION SYSTEMS Inc 11 Oct 1971 [10 Dec 1970] 47318/71 Heading H3W In an amplifier with inverting and non- inverting input terminals, a resistive network is connected between the inverting input terminal and output terminal, and the voltage at a point in this network chosen such that the fundamental input signal is not present is fed via a further phase-inverting amplifier into the non-inverting input of the main amplifier, so as to cancel out harmonic distortion. Signal from source 201 with internal impedance 202 is applied via resistor 204 to the out-of-phase input 215 of amplifier 206. The output is fed to terminal 212 and also is fed back to the input 215 of the amplifier via resistors 209, 210. These are so chosen that at their common point 214 the fundamental signal component is absent, leaving a residue comprising distortion and noise which is fed back over phase-reversing amplifier 211 to the in-phase input terminal 216 of amplifier 206. The specification also describes an arrangement with a further independent negative feedback resistor between output and input of the amplifier (Fig. 3, not shown) and an additional modification of this in which the fundamental signal cancelling path is fed from a fraction of the amplifier output (Fig. 4, not shown).
