Title: Improvements in and relating to folding mechanism for printing machines
IPC: B41F13/56
Filed: 1929-11-30
Abstract: 339,480. Triggs, W. W., (Wood Newspaper Machinery Corporation). Nov. 30, 1929. Cutting and delivery apparatus.-In a web printing-machine fitted with longitudinal folders 13 and transverse folders and cutters 11, 12 coacting with delivery devices, the transverse folders &c. are mounted in adjustable frames 10, 36, which are movable by screw mechanism in guideways on the base of the machine in a direction transverse to the original direction of travel of the web. This adjustment enables the transverse folders to be set so that their folding blades act correctly when dealing with webs of different widths without the necessity of altering the adjustment of the blades. As shown in Fig. 1, the longitudinal formers 13 and folding rollers 14, 15 are shown in full lines as set. for dealing with wide webs, and in dotted lines as set for dealing with narrower webs, and the transverse folding mechanism is also shown in the corresponding positions of adjustment. Fig. 3 shows the application of the invention to a machine in which a wide web is slit by cutters 32, 31 into four webs before passing over the formers 13 which act to superpose the cut webs which are not joined by a fold after passing over the formers. The frame 36 of the transverse folder can in this case be set if desired to receive all the webs from the formers 13, and it is adjusted centrally between the formers. A fixed transverse folder can coact with one former when the products from each former are dealt with separately, or two adjustable folders 41 may be used.

Title: Improvements in or relating to target structures for use in colour television tubes
IPC: H04N9/16
Filed: 1954-12-22
Abstract: 773,339. Colour television tubes. CHROMATIC TELEVISION LABORATORIES, Inc. Dec. 22, 1954 [Dec. 22, 1953], No. 37000/54. Class 39(1). Correction of the pin cushion and barrel distortion which gives colour dilution in a colour television tube is obtained by varying the spacing of either the phosphor groups or the deflection grid wires so that the ratio of the group width to the grid aperture width is greater at the centre of the target than at the edges thereof. The mathematical relationships enabling the ratios to be calculated are given in the Specification. In Fig. 7, the spacing of the grid wires 47, 47<1> is uniform, but the separation of the groups of phosphor strips 45g, 45r, 45b increases outwardly along the central horizontal line whilst remaining constant at the top and bottom edges. In Fig. 8 (not shown) the group separation is constant, but the grid spacing is less along the centre line, the spacing being achieved by accurate notching of the supports and by deforming the damping rods so that they hold the grid wires at the desired separation in the centre portion. The corrected widths of the phosphor groups may be obtained by laying the pattern out on a large scale and reducing photographically to proper size for the production of silk screen stencils or other printing devices therefrom. A second order of correction may be introduced by making a gelatin print of the screen pattern, mounting in a frame with sides bowed outwardly and stretching the frame and gelatin, the stretched frame being rephotographed. Similar corrections are imposed on screens of crossed colour strips and their accompanying crossed colour control wires, Fig. 2 (not shown). Specifications 721,523, 722,282. 757,071 and 757,786 are referred to.
