Title: Improvement in blankets for printing presses, and process of printing employing the same
IPC: B41N10/06
Filed: 1926-01-26
Abstract: 246,525. John, R. Jan. 26, 1925, [Convention date]. Blankets ; offset printing.-A rubber or other elastic impression or off-set blanket is secured in an unstretched condition to a metal backing sheet by which it may be secured to a cylinder or other member. The blanket may be secured to the cylinder &c. in such a way as to allow it to have a slight bodily movement thereon. An ordinary blanket A consisting of layers of rubber and fabric is secured to a flexible backing sheet 6 of zinc, aluminium, iron, copper or other metal by means of a thin sheet of celluloid. The ends of the blanket are clamped by screws 9 between strips 7, 8 by which it is secured to the cylinder 10. The strip 8 on the leading end of the blanket is mounted in a recess 13, Fig. 4, in the cylinder, bearing against a shoulder 14 and being held down by a set-screw 15. The strip 8, Fig. 5, at the opposite end is mounted in a recess 17 in a roller 16 and is pressed against a shoulder 18 by a set-screw 19. Rotation of the roller 16 by the pull of the blanket is prevented by the usual ratchet-and-pawl device. The metal sheet 6 terminates short of the rear clamping device so as to leave a free portion of blanket a that can adapt itself to the curvature of the roller 16 and that will allow a slight bodily movement of the sheet 6 and blanket during the operation of the press. In using an offset blanket, mounted as described above, in a rotary offset press, the printing plate on the plate. cylinder is packed up with paper so as to increase the diameter of the plate cylinder and cause it to have a slightly greater surface speed than the blanket. This results in a slight bodily creep of the blanket on its cylinder when receiving an impression thereby preventing wear of the blanket by friction.

Abstract: 147,531. American Coke & Chemical Co., (Assignees of Roberts, A.). July 11, 1919, [Convention date]. Coke ovens.-In a coke oven structure in which each oven with its recuperator forms a separate and complete unit, the waste gases from the heating-walls are exhausted into a common flue 40, and pass thence through distributed openings 63 into two flues 43, 44 connected by end ports 46, 47 with the recuperators. Each oven is associated with its own heating-walls 20, 21. to which combustible, gas and air are supplied at the top, the products of combustion passing downwards through a network of interconnected passages formed by notched blocks constituting the wall. The gas burners open into small combustion chambers 34, to which air is admitted from chambers 32 in communication with the air passages of the recuperators. Two recuperator chambers are arranged end to end beneath each oven, and are built up from tiles or flues 51 separated at intervals by horizontal and vertical spacer blocks 52, 53 respectively. The vertical 'blocks 53 in adjacent rows are set between and at the sides of the pairs of tiles 51 respectively so that zigzag passages are provided for the air to be heated. The passages formed on the tiles 51 open into end headers divided by horizontal partitions so that the waste gases travel through the recuperator in a zigzag path. Longitudinal passages 71, 72 connect the air spaces of the two recuperators at their upper end, and from these lead vertical flues 36 in communication at their upper ends with the chambers 32. The flues 36 for each heating-wall are connected by longitudinal air. equalizing passages 38, 39. The Specification as open to inspection under Sect. 91 (3) (a) comprises also arrangements for supplying gas in two stages to the heating-walls, a construction of burner nozzle for the additional supply, and arrangements for dividing the heating-wall into a number of independently-controlled zones. This description does not appear in the Specification as accepted, but forms the subject-matter of Specifications 165,733 and 165,734. In the Specification as open to inspection the gas and air supply arrangements at the top of the heating-wall are described in greater detail than in the Specification as accepted, and these arrangements form the subject-matter of Specifications 165,735 and 165,736.

In the construction described, the display chamber window is formed by a plurality of parallel glass sheets 20, and electric lamps 21 giving a white or coloured light are provided. The fog is formed by atomizing by nozzles 17 liquid, e.g. water or brine, supplied through pipes 18. The condensed liquid passes through a pipe 15 to a chamber 7 where it is cooled by refrigerating pipes 9 and is then withdrawn and forced by a pump 10 through a charcoal or other filter 12, which cleanses or sterilizes or both, and thence again through pipes 18 and nozzles 17. The apparatus has also storage chambers 2, one of which may be kept at freezing and the other at chilling temperature. A fog is maintained in these chambers by atomizing the liquid through nozzles and the condensed liquid is returned through pipe 14 to chamber 7. The chambers 2 have cooling pipes 4 through which and pipes 19 in chamber 1 is passed cold brine or water, or a refrigerating gas supplied from a compressor engine 11, which drives pump 10, and a condenser or cooler 13. The chambers 1, 2 have doors 22, 23 which, with the walls of the chambers, are made of non- conducting material. Where substances, including flesh meat and fruit, in case of which contact with moisture is undesirable, are to be kept in the apparatus, the fog atmosphere may be omitted, or only used intermittently, and the cooling effected by the cooling coils. Means may be provided whereby the supply of atomized liquid to chamber 1 is cut off and turned on automatically on opening and closing door 22. In a modification, the liquid may be filtered to remove dirt &c. before passing back to chamber 7, or between this chamber 7 and filter 12.
