Title: Improvements in colour printing
Inventor: DIXON WILLIAM MURRAY
IPC: B41M1/30
Filed: 1965-05-26
Abstract: 1,095,814. Printing processes. FORMICA INTERNATIONAL Ltd. May 19, 1966 [May 26, 1965], No. 22382/65. Heading B6C. A method of colour printing upon web or sheet material consists in subjecting the matter to a first operation, whereby it is printed with a first overall pattern comprising zones of spaced substantially square-shaped inked areas, and thereafter subjecting the material to at least a second operation, whereby the first overall pattern is overprinted with at least a second overall pattern substantially identical in configuration, size and colour to the first overall pattern but angularly disposed in relation thereto. Although overprinting with two or more identical patterns is within the scope of the invention good results are apparently obtained with a single overprinting at an angle of between 40 and 50 degrees, and more especially at 45 degrees to the first printing. In the described apparatus intaglio printing cylinders are used, the square image areas being preferably longitudinally and circumferentially aligned.

Filed: 1966-05-19
Abstract: 1,150,289. Explosive charges. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). 19 May, 1966 [22 May, 1965], No. 22402/66. Heading F3A. [Also in Division H2] A current pulse is generated by causing a current carrying circuit 2 to be collapsed by detonating an explosive material 6 so as to reduce the inductance of the circuit and produce an electric current through a load 5 which is protected against the explosion by a protective wall 13. Two flat copper conductors 2 are connected via a transmission line 4 to the load 5. An initial flux is produced by a current from a bank of capacitors 9 and detonators simultaneously cause the plastic explosive 6 surrounding the conductors 2 to progressively collapse on to a conductor 10. The conductors 2 then take the forms shown by lines 11 and 12 and so produce the current pulse. The wall 13 protects the load 5 and any intruments connected to it. In a similar arrangement (Fig. 2, not shown), the conductors are formed by two coaxial cylinders (15, 16) which are connected to a toroidal load 5. In a further arrangement (Fig. 3, not shown) the explosive is arranged within a conductor 18 which is caused to collapse outwardly when the explosion occurs.

Abstract: 1329064 Composite photography EASTMAN KODAK CO 19 April 1971 [4 March 1970] 23061/71 Heading G2A  In the making of a tamperproof identification card on which the image of a person 2 occurs at a different magnification to that of the image of a data card 4, a transition zone (13) Fig.1A, (not shown) is formed between the two images, the zone being blurred so that the edges between the zone and the images are not clearly discernible. Photographic film 1 in a camera 5 is exposed via an objective 7 to the data card 4, light from a part thereof being blocked by a mask 11. The film also receives light from a person 2 via a mirror 8, lens 9 and semi reflecting mirror 10, the image of the person 2 being defined in size by a mask 12 complementary to the mask 11. The masks 11, 12 are so spaced from the lens 7, 9 respectively as to cause vignetting, or blurring, of the internal and external edge portions defined by the masks on the film 1. The mirrors 8, 10 and lens 9 are mounted in a rotatable detachable housing 12. A lamp 17 may be provided to illuminate the card 4 and the person 2. In another embodiment Fig.3 (not shown), the positions of the person (2a) and the card (4a) are reversed, and the lens 9 is replaced by a positive lens (18). In another embodiment (Fig.4), a sequential multi-lens camera 19 contains an objective 21 and mask 11b for forming a masked data card image on a film 1b when this is at a position A, and mirrors 8b, 23, mask 12b and second objective 24 for forming an image of a person 2b on the film 1b when this is at a position B. As before, masks 11b, 12b are complementary, so there is no double exposure of the image areas, and no substantial double exposure of the transition zone. The invention may be extended to more than one object in each case.

Title: Improvements in or relating to weighing machines
IPC: G01G7/04
Filed: 1955-08-11
Abstract: 805,556. Weighing-apparatus. TATE & LYLE Ltd., HILL, S., and RUNDELL, J. T. Nov. 5, 1956 [Aug. 11, 1955], No. 23145/55. Class 40 (1). In a weighing-machine, the flow of material to be weighed from a hopper 2 into a receptacle 1 mounted on a pivoted beam 3 causes deflection of the beam which displaces from its null position the core 8 of a differential transformer 9, the amplified, rectified and smoothed output of which is fed to a coil 5 attached to the beam 3 and disposed within the air-gap of a permanent magnet 7, to exert on the beam 3 a force opposing its deflection due to the load, and the voltage across a resistor 19 in the coil circuit is utilized to control servo means 20, which controls the flow of material from the hopper 2. At a predetermined weight the flow is stopped and the contents of receptacle 1 are discharged, as by doors 23 controlled by mechanical or electromagnetic means (not shown), for example into one of a number of packets on an intermittentlymoving conveyer band (not shown). The times of recommencing the flow and of opening and closing the doors 23, may be controlled by a cam-shaft rotating in synchronism with the driving mechanism of the band. In a preferred embodiment the receptacle 1, to which both the coil 5 and the core 8 are attached, is mounted on leaf-springs for vertical movement within an annular magnet.

Title: Washing machine for spun cakes of artificial silk
IPC: D01D10/04
Filed: 1930-07-31
Abstract: <PICT:0356415/IV/1> <PICT:0356415/IV/2> <PICT:0356415/IV/3> A washing machine for spun cakes of artificial silk threads comprises a carrier placed freely liftable on supports of a vat, and provided with crank mechanism connected by means of hanging devices with frames on which loosely detachable rods or reels for the thread cakes are arranged. The crank mechanism and hanging devices may have such dimensions that at each turn the frame together with the thread cakes is dipped into and out of the treating liquid.  It is preferable to rotate the cranks slowly in order that when the cakes are lifted out of the bath, liquid may drain out of them.  The machine may be constructed in double form, both sides of the carrier being fitted with crank mechanism, and in order to balance the machine the mechanism on one side should differ in phase from that on the other side by 180 DEG . If a common vat is provided, this arrangement of the mechanism will result in thorough stirring of the liquid.  When several different treatments are required, a number of vats are placed in a row and the carrier is moved from one place of treatment to another by means of a travelling crane running along a track which may be endless so that the yarn carrier may be brought back to the starting point.  As shown in the drawings, the ends of a vat a have supports b with rests c. On these rests a carrier d with crank mechanism i may be placed.  On the crank mechanism, the frames m are suspended by hanging devices l. Frames m are provided with a number of rods n on which are placed the spun cakes o either directly or by means of small expansible reels. A shaft f provided with worms q is turned by a motor e.  This gives the crank shaft h a slow rotation by means of the worm wheels g. The cranks i, k also receive a rotary motion and raise and lower the frames m by means of the hanging devices l.  The thread cakes are thus immersed in and lifted out of the bath at regular intervals.
