Title: Improvements in producing dye-impression two-color positives and in material and apparatus therefor
IPC: G03C7/20
Filed: 1929-07-03
Abstract: 339,319. Thornton, J. E. July 3, 1929. Divided on 339,296. Printing processes.- Two-colour pictures are produced by dye-impression printing from a duplex dye-printing plate as described in Specifications 339,296; and 339,321, [Class 98 (ii), Photographic processes &c.], having upon its opposite faces a pair of dye images of complementary character, by (1) printing simultaneously from both sides of the duplex plate by pressurecontact upon two sheets of dye-absorbent non- sensitive material provided with registration holes and placed one on each side of the duplex plate; and (2) 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 positive 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. One 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 to both sides. The rolls may be absorbent or not, and each is fed with dye by 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, gum, 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. Specification 316,388 is referred to in the Provisional Specification.

A selector of container closing capsules C<SP>1</SP>, C<SP>2</SP>, C<SP>3</SP>, Figs. 1, 2, of conventional type consisting of a wall a of revolution, an end wall b which is plane and without projections and with an edge c to the wall a defining a cavity d, comprises a horizontal circular plate 2 rotatably mounted about axis X-X with a fixed cylindrical wall 8 with a gap from n to m constituting with a fixed guide 9 an outlet passage 10 for capsules heaped on the plate 2, and a rotor R arranged to feed capsules such as C<SP>1</SP> whose cavity d is facing upwardly to a discharge passage 15 and allow capsules such as C<SP>2</SP> whose cavity d is facing downwardly to a discharge passage 16. If the capsules such as C<SP>3</SP> on the plate 2 are in a reclining position they are returned to a vertical position C<SP>1</SP> or C<SP>2</SP> by the edge of a plate 26 on the rotor R when they arrive in the passage 10. The rotor R comprises two sets of balls 30, 34 biased respectively by weights 32, 37, the former set acting as selecting elements and the latter set as a sort of starwheel drive to place the capsules under the balls 30. Capsules fed by the plate 2 to the passage 10 in the inverted position C<SP>1</SP> are conveyed to the passage 15 since one of the balls 30 enters the cavity d (see 30a, Fig. 2) drops into it (30b) and abuts (30c) at p the inner face of the wall a and then abandons it (30d). Capsules in the upright position C<SP>2</SP> have their adherence to the plate 2 increased by the weight of the ball 30 and the weight 32 and are driven by the plate 2 to the passage 16. In the modification shown in Fig. 5 selecting fingers 39 raised and lowered by a ball 47 running on a ramp 45 are adapted to select polyethylene closing capsules having a wall a adapted to cap the neck of a bottle, an end wall b and a shallow cavity d the end e of which is a grid or filter. These capsules can be employed after cutting the end wall b for breaking a stream of liquid passing therethrough and retaining the drops of liquid which might trickle when the bottle is returned to its vertical position and are of utility as pouring caps.
