Title: Improvements in or relating to the production of two-color pictures by photographic dye-impression methods
IPC: G03C7/20
Filed: 1929-07-03
Abstract: 339,296. Thornton, J. E. July 3, 1929. Printing processes.- A process of producing two-colour pictures by dye-impression printing consists (1) in preparing a duplex dye-printing plate as described in Specification 339,321, [Class 98 (ii), Photographic processes &c.], having upon its opposite faces a pair of dye images of complementary character, produced by exposing in a camera from one side only a sensitive film bearing complementary colour-sensitive emulsions on opposite sides with associated light filters, developing the images., treating them to render the gelatine dye-repellant in proportion to its silver content, and dyeing with complementary colours the gelatine which remains dye-receptive; (2) in printing positive images simultaneously from the duplex plate as described in Specification 339,319 by pressure-contact upon two sheets of dye-absorbent non-sensitive material provided with registration holes and placed one on each side of the duplex plate; and (3) in cementing together in register and face to face the printed dye-positives. Presses and other apparatus are described for dyeing the printing-plate, for printing therefrom on to the sensitive material, and for cementing together the positive prints. The press for applying dyes to opposite sides of the printing-plate may comprise two dye pads carried by rigid metal &c. plates hinged together in. book form with a fastener to retain them in closed position. On of the plates may be weighted, or may be double with springs between the two parts. Each dye-pad carries a mark to indicate the dye to be used on it. The printing-plate is dyed on both sides simultaneously by placing it between the dyed pads and closing the press. For considerable work, the plate is passed one or more times through a machine provided with dyeing rolls which apply the dyes simultaneously on both sides. The rolls may be absorbent or not, and each is fed with dye bv a roller which receives dye from a ductor roller rotating in a trough of the dye. The material upon which the dye-prints are made comprises paper or film bearing a coating of soft or hardened gelatine. albumen, glue, starch &c. Two sheets, or a single folded sheet, are used ; either or both of the sheets or folds may be of the strippable kind, and both are provided with registration holes. The dye-print plate is placed between the sheets or folds, and the whole is inserted into a press comprising padded metal plates hinged together which bear registration pins fitting the holes in the print sheets. After printing, and if desired drying and hardening. the sheets are coated with adhesive (which may alternatively contain the hardening agent), are registered again on the registration pins in the same or a similar press, and are pressed into adhesive contact. One or both paper supports are stripped off, leaving a two-colour picture in dyed gelatine. If both supports are removed, the transparency may be mounted on any opaque support, or between transparent covers.

Title: Two lid counterbalance hinge mechanism
IPC: E05F1/12
Filed: 1972-05-02
Abstract: 1385388 Spring units WEBER KNAPP CO 2 May 1972 [13 Dec 1971] 20428/72 Heading F2S [Also in Division E2] A single counterbalance hinge mechanism is connected, via parts 14, 18, to two lids 16, 18 both pivoted at 24 to a stationary part 12. The mechanism employs two springs: spring 42 which is maintained in compression and which expands to counterbalance the upward movement of either lid, and spring 44 which is normally uncompressed but which acts in opposition to spring 42 when lid 20 is raised-the mechanism can thereby accommodate a lid 20 lighter than lid 18. A bolt 46 free to slide in plate 60 on part 14 is secured at one end to a connector 66 which is joined by a link 80 to part 18; a pivot 30 which joins link 80 to connector 66 being engaged in slot 28 on the stationary part 12. Spring 42 acts between a retainer 52 and a nut 50 adjustably positioned on the bolt 46, and spring 44 acts between a washer 72 engaged on a stepped portion of the bolt and a plate 70 slidably mounted on the bolt. When lid 16 is raised plate 70 remains engaged against connector 66 and spring 44 does not act; however when lid 20 is raised pivot 30 can move to the left in slot 28 and the connector 66 moves away from plate 70 which engages against stop 34, allowing the spring 44 to act in opposition to the spring 42. When both lids are in the nearly closed position the counterbalance force is reduced so that the lids close by gravity. A friction braking sleeve 54 is biased by spring 42 into member 56 to brake movement of the rod 46.

Title: Improvements in or relating to pressure or load control device for linkage of metal working presses
IPC: B30B15/28
Filed: 1950-08-25
Abstract: 674,593. Metal-working presses. CLEARING MACHINE CORPORATION. Aug. 25, 1950 [June 12, 1950], No. 21064/50. Class 83 (iv). A metal working press has a load control device associated with the mechanism for reciprocating the slide the device comprising a yieldable member mounted on the slide, a lever arm connected at one end to said yieldable member and eccentric pivot means connecting the other end of said lever arm between the slide and the said mechanism, whereby relative movement between the slide and the mechanism tending to produce an overload causes rotation of said lever arm about said eccentric pivot means against the pressure of said yieldable member. A slide 1 is reciprocated by a crank 5 on a shaft 4. The load device consists of a fluid-pressure cylinder 7 having a piston 8 attached to a rod 13, the cylinder being pivoted to a lug 11 on the slide. The rod 13 is pivotally connected to one end of a lever arm 16, the other end of which has circular side members 17 and 18 (Fig. 3), and an intermediate portion 19 partially surrounding an arcuate recess 20. The side members 17 and 18 carry an eccentric pin 22 and the lower end of a link 6 attached to the crank 5 extends into the opening 20 and surrounds the pin 22. The side members 17 and 18 of the lever are carried in bearings 24 mounted on an adjustable member 28 comprising a screw-threaded member 29 carrying a bevel gear 30 which has a flange 31 adapted to rotate in an annular recess in a sleeve 32. A stop 3 on the arm 16 limits the downward movement of the arm and the piston 8. In operation, when the load exerted by the slide multiplied by the distance between the eccentric axes 21 and 23 exceeds the fluid pressure on piston 8 multiplied by the length of lever 16 the lever rotates and raises the piston rod 13 and piston 8 so allowing the crank and link to complete their downward movement without overloading the press. The centre of the pin 22 may be on either side of the centre line passing through the crank, the screw and the lever axis 21. Also, the centre line through the crank and screws may pass through the centre of pin 22. In a double or triple-action press wherein the blank holder 34 is reciprocated by a plurality of cranks (not shown), and links 35 (Fig. 4), the lower end of the links being attached to adjustable screw members 37, the load-control device is associated with the adjustable screw members by mounting the cylinders 42 (Fig. 4) on a bar 41 secured to the screw members. The piston rods 46 are' attached to the lever arms 48 which are eccentrically mounted in bearing supports 36 as previously described. In this type of press by varying the pressure in the cylinders 42 varying pressures may be exerted at each corner of the slide. Adjustment of the press is effected manually by means of upper and lower collars 39 and 40 respectively on each adjusting screw 37, each collar abutting against a boss 38. This adjustment may be carried out mechanically by means of worm gearing and an electric motor.
