Title: Improvements in machines for photographic contact printing on to sensitised cylinders
IPC: G03F7/24
Filed: 1937-09-14
Abstract: 494,446. Photographic contact-printing apparatus. PAPER PATENTS CO. Sept. 14, 1937, No. 24979. Convention date, March 13. [Class 98 (ii)] A machine for photographic contact-printing on to the sensitized surface of a cylinder from a flat transparency which is moved in tangential contact with it as it is rotated, is provided with means to allow a slight slippage at the point of contact when the length of the transparency differs slightly from the circumference of the cylinder. In the form shown a base 1 supports uprights 3 which carry clamp members 39 supporting the lighting apparatus and printing roller and guides 29 for the framework 27 which carries an intermediate framework 31 to which is attached the transparent original 26. The framework 29 is moved vertically by threaded rods 7 engaging it at 33, and rotatable through gearing 23, 24 by a shaft 17 belt driven from an electric motor. One of two belts, giving different speeds is selected by the clutch 20. The sensitized cylinder 35 is carried in bearings 41 mounted with adjustments 43 on the beam 37 clamped to the uprights 3 by the members 39. These members 39 also carry cross beams 59, Fig. 3, with horizontal and vertical adjustments (not shown) which carry members 53 (shown in detail in Fig. 6), to define a slit 66 through which light from the arc 81 is directed by the water-cooled reflector system 83, and to press the transparency into good contact with the cylinder. Each is attached to a number of levers 54 pivoted on spindles 57 and acted on by springs 55. When the eccentrically mounted rods 63 are rotated they act on the levers 54 to remove the pressure from the transparency. The gear 89, Fig. 1, mounted on the printing cylinder spindle is equal in diameter to the cylinder and engages a helically cut rack 91 mounted on the framework 27. The rack is pivoted at its middle point, Fig. 11, and is adjustable by screws 93 giving an effective change in length to produce the slippage of the transparency on the surface of the cylinder. For measuring purposes, a scale 95 is provided, Fig. 1, to move with the transparency and co-operate with a crosshair 97 carried by the member 39. The other member 39 carries a cross-hair which is used in co-operation with another carried by a radial arm 45 to ascertain precisely when the cylinder has made a complete revolution.

Title: Improvements in or relating to door attachment devices for exclusion of draught
IPC: E06B7/20
Filed: 1946-08-26
Abstract: 616,076. Draught excluders. HOVENS, P.J. H., and HOVENS, P. J. Aug. 26, 1946, No. 25463. Convention date, May 19, 1943. [Class 20(iii)] A draught excluder for a door is automatically and silently operated by apparatus comprising a spring loaded actuating rod which is displaced by the closing of the door and, through a liquid power transmission device, moves the excluder to the operative position. In the form shown, the excluder proper, which consists of a vertically displaceable metal bar 9, provided with an elastic material surface 10, is housed in a groove 5 in the bottom edge of door 1, this groove being deepened near the centre to provide a recess 6. A passage 7 housing a spring-returned push-rod 28 is provided between recess 6 and the hinge side 8 of the door. The actuating mechanism consists of a metal frame 14 having two cylinders 19 each having a piston 20 bearing on the bar 9 and adapted to force it down against the action of the return springs 34. The cylinders 19, through conduit 17 and opening 21 communicate with an operating cylinder 22 having two pistons 23, 24 located on either side of the opening 21, piston 24 co-operating with the rod 28 and piston 23 with a compression spring 26. The cylinders and passages are filled with a liquid, preferably oil, which then serves to lubricate the moving parts. When the door is closed the head 27 engages the door frame and the rod 28 displaces piston 24. Since oil cannot pass quickly through the restricted opening 21, piston 23 is displaced against the spring 26 which subsequently expands, effecting the smooth downward movement of the pistons 2C by gradually forcing the oil through the opening 21. This device also protects the excluder from damage if some obstruction on the floor should prevent its full movement.
