Title: Improvements in and relating to the feeding of paper to a printing or other machine
IPC: B65H3/02
Filed: 1924-04-24
Abstract: 227,690. Bullock, C. A. H. April 24, 1924. Sheet - separators; pile tables and supports.-Sheets are fed to printing and like machines, such as that described in Specification 190,544, by separating the sheets from a. stack of sheets arranged between adjustable side guides on an inclined feed board 1, the edges of the sheets resting on a pivoted clip 8 provided with a bent lip 8<a>. The separation of the top sheet is effected by displacing the pack bodily in the plane of the sheets by giving the clip 8 an oscillating motion by means of a lever arm on its shaft 9, which has a depending lug engaged by a serrated cam giving the clip a vibrating as well as an oscillating motion, so that the pack is simultaneously raised along the surface of the board 1 and joggled to facilitate separation of the sheets. When the stack has been raised to its uppermost position, a friction pad 21 on a shaft 22, carried by a reciprocating carriage 23, is moved into contact with the stack, and the stack is then permitted by its operating cam to fall by gravity, the pad 21 preventing the return of the top sheet and thus separating it from the stack. The feed board 1 is then moved in a clockwise direction about an upper pivot 3, and so the front edge of the stack is gripped by the lip 8a and the carriage 23 then descends and the pad 21 feeds the top sheet over the lips 8<a> and allows it to pass to the printing or other machine. The pivotal movement of the board 1 is controlled by a spring-pressed lever 17 provided with a projection 15 operated by a cam 14 to move the board 1 in a clockwise direction. Normallv a spring keeps the roller 18 on the lever 17 out of contact with the board 1, and the board can then move in a counterclockwise direction under the action of gravity to an extent which is limited by a rack 38 having sloping teeth engaging a fixed abutment to limit the backward movement '1f the board 1. The pad 21 is mounted on a shaft 22 geared to a sector 26 on a shaft 27, Fig. 6, acted on by a spring which normally tends to move the pad 21 into engagement with the stack. this movement being prevented by a pawl 29 on a larger pawl 30 controlled by a strong spring 33 for keeping the pawl 29 in engagement with the sector gear 26. The. connecting-rod 32 for reciprocating the carriage 23 acts through the pawl 30. When the carriage 23 engages a fixed stop 34, the pawl 30 is moved to release the pawl 29 from the gear 26 and permit the pad 21 to contact with the stack. On the return movement of the carriage 23, the gear 26 is re-set by the action of a stop 35 on a projecting arm 36. Specification 218,466 is referred to.

Abstract: 912,835. Electrophotolithographic printing plates. PLASTIC COATING CORPORATION. March 25, 1959 [April 10, 1958], No. 10273/59. Drawings to Specification. Class 98 (2). [Also in Group XXXVI] A lithographic printing plate is made from an electrophotographic plate adapted for attachment to'the plate cylinder of a printing press by charging the plate, exposing and developing it in the conventional manner using an hydrophobic and oleophilic toner, and then treating in acidified ferrocyanide solution to render the untoned areas hydrophylic and oleophobic. An electrophotographic plate comprises a selfsupporting flexible sheet of synthetic resin, provided on one face with a thin flexible metal film carrying a layer of finely divided photoconductive zinc oxide dispersed in a matrix of filmforming insulating material. The synthetic resin sheet may consist of any of the polymeric materials listed in the Specification but is preferably of polyethylene terephthalate. A metal film consisting of aluminium, zinc, gold, silver, platinum, tungsten, cadmium, nickel, chromium, tantalum or molybdenum is applied to the sheet by vacuum metallizing or cathodic sputtering. When polyethylene terephthalate sheet is used it is precoated with the copolyester of ethylene terephthalate and ethylene sebacate to improve the adherence of the preferred metal aluminium. To improve the adherence of the metal to polyethylene the latter is subjected to a pre-heat treatment, or a surface treatment with a strong oxidizing agent. Polytetrafluorethylene on the other hand is prepared for coating by treating with sodium dissolved in anhydrous ammonia, and then coating with lacquer. The photoconductive zinc oxide is applied to the metallized sheet in the form of a suspension in a solution of film-forming material in an organic solvent. Silicone, phenolic, polyester, polymethacrylate, and styrenated alkyd resins, vinyl acetate-vinyl chloride copolymer resins, polyvinyl chloride, polyethylenes, polystyrene, copolymers of n-butyl and iso-butyl methacrylates, polymerized iso-butyl methacrylate, and styrene-butadiene copolymers are used as film-forming materials. A number of suitable coating solutions are specified in all of which 1 part by weight of zinc oxide is mixed with from 2.6-4À5 parts by weight of film forming material.

Title: Devices adapted to eliminate or to reduce speed oscillations or vibrations
IPC: F16F15/14
Filed: 1933-04-06
Abstract: 401,962. Vibration-dampers. SALOMON, F. M. M. B., 3, Rue de l'Universite, Paris. April 6, 1933, No. 10333. Convention date, April 7, 1932. [Class 108 (iii).] The elimination of superimposed vibrations or oscillations in any system but particularly in continuously rotating shafts is accomplished by means of auxiliary masses which are preferably free and which absorb the vibrations &c. by the change in their radial and tangential inertia forces. Fig. 1 shows part of a fly-wheel 3 keyed to a shaft 1 the speed oscillations and the flexure vibrations of which are to be absorbed and as shown the devices are arranged at different points and are each adapted to absorb vibrations of its own frequency or combination of frequencies. The auxiliary masses may be either balls or rollers. Figs. 1 and 4 show a recess in the flywheel comprising a core 6 and a race 7 in which a roller 8, 10 is free to roll, the roller being hollow and containing a ball 9 also free to roll. Constant speed of the shaft 1 causes the roller and ball to assume a position of equilibrium which is disturbed by a change of speed due to a superimposed vibration so that the movement of the roller and ball absorbs the speed variation if of its own frequency or frequencies. Fig. 4 also shows an auxiliary mass comprising liquid 68 free to move in the recess between a core 67 and an outer ring 66. In the device shown in Fig. 1 comprising a ball 16 free to move in a double curvature race, flexure of the shaft as well as a torque disturbance are absorbed as indicated in Fig. 1a and such devices may be arranged at intervals along a shaft. A device for absorbing disturbances of another frequency comprises a series of balls 39 spaced by a cage 53 and arranged to move freely in a race 37, 38, Figs. 1 and 2. Fig. 2 shows also an epicycloidal race 45, 48 and ball 46. Fig. 7 shows devices for absorbing disturbances which are at an angle to the shaft and comprise a tube 103 with a series of recesses having balls or rollers of different mass and different radii of gyration to absorb different frequency disturbances. Fig. 8 shows an arrangement of cranks 124, 126, 128 in which the absorption devices may be arranged on the flywheels or discs 125, 129. Various other arrangements of races, such as spiral, and auxiliary masses are described in the Specification.
