Title: Sheet separating mechanism
IPC: B65H3/48
Filed: 1971-05-20
Abstract: 1347282 'Feeding sheets EASTMAN KODAK CO 20 May 1971 [25 May 1970] 15963/71 Heading B8R Sheets are separated from the top of a pile 6, Figs. 2 and 4, supported on a member 8, by a plurality of separating devices spaced across the front end of the pile. Each separating device comprises a suction separator 4, and an air supply tube 18 secured to the member 8. The tube is provided with a longitudinal slot 22 through which passes a finger 26. The finger is movable between a lower position, Fig. 2, in which it rests on the pile and restricts the effective size of the slot, so that as the finger starts to rise, air passes through at high velocity and low volume to separate the front edges of the uppermost sheets. When the finger is in its upper position, Fig. 4, the air passes through at low velocity and high volume to maintain the sheets separated as the separator 4 begins to rise, pulling the front edge of the top sheet from under the fingers. The fingers of all the devices are moved by a common rod 38 driven through a bell-crank 40. In another form, Fig. 8, the finger 62 is formed as the top of a tube 54 fitting in the air supply tube 50 and having a slot 60. In the lowest position, the slot is below the top of the tube 50. When a solenoid valve 64 is opened, air in the tube 50 forces the tube 54 upwards. In another form, Fig. 9, the air supply tube 82 has a narrow slot 84 opening into a wide recess 80. The finger 70 thus in its lower position shuts off air from the recess but not from the slot. The air is guided by a curved surface 88 between spaced flanges 90, 92.

Abstract: 1,092,182. Electro-photographic processes. ITEK CORPORATION. April 14, 1965 [April 15, 1964], No. 16069/65. Heading G2H. [Also in Division G1 ] A process for producing a visible image on a photo-conductive medium especially such a medium as described in Specification 1, 043, 250, (Division G2-G3) comprises projecting an electron beam on to the medium, the medium being thus rendered chemically reactive in the portions exposed to the beam to form a latent image of the beam pattern and then treating the medium to render the latent image visible. As shown, a web 20, e. g., of titanium dioxide on a substrate of titanium passes through a heater 28 to deactivate the web. The web is advanced through vacuum chamber 12 such that an electron beam from a gun 10 and controlled by plates 16 strikes the web to cause the titanium dioxide to become imagewise chemically reactive. The latent image formed is developed by contact with a solution containing metallic ions e. g. silver nitrate. The image may be intensified by application of a silver halide developer which deposits further free metal on the web on the deposited silver.

Filed: 1925-08-11
Abstract: 254,729. Corn Products Refining Co., (Assignees of Newkirk, W. B.). Jan. 17, 1925, [Convention date]. Glucose.-Substantially pure granular or crystalline glucose is prepared by completely melting starch-converted glucose having a purity exceeding 90 per cent, bringing about supersaturation of the melt at a temperature to produce anhydrous crystals without the introduction of seed crystals. agitating the magna during crystallization to keep the solid phase, as formed, in dispersion in the liquid, and then centrifuging to separate the crystals from the mother-liquor. The magma should be purged of its mother-liquor while in a fluent or semi-solid state. The sugar, which may be hydrate or anhydride, or a mixture of both, and of 95-96 per cent purity, is melted to a density of about 40‹ B. and crystallized at about 120‹ F. or above, anhydride crystals being obtained. Seed crystals may be added under some conditions. As the solid phase increases, the temperature may be lowered, causing more rapid crystallization. Reference is made to the use of a lower initial temperature if liberal seeding with anhydrous crystals is effected at the start. After centrifuging, the crystals may be washed, giving a very pure sugar. The conditions under which the anhydrides of alpha- or #- glucose are formed in the crystallization are also described in Specifications 227,140, 232,160, and 232,938 are referred to.

Title: Improvements in or relating to casting building units
IPC: B28B15/00
Filed: 1958-05-22
Abstract: 853,073. Casting building units. BRUNTON, J. E. C. Oct. 16, 1958 [May 22, 1958], No. 16509/58. Class 87(2). [Also in Group X] On a bed A of porous material, e.g. sand, mould walls are laid, in the form of strips B which may be produced by extrusion and which are of a material which is friable when dry, e.g. lime, clay, or Roman cement. A wet mixture of cement and light weight aggregate is poured into the mould so formed from a hopper which runs on rails X and so can traverse the moulds. (The mould walls of separators may also be extruded from a mobile container). Excess water is soaked away by the porous bed and atmospheric pressure assists in compacting the concrete into castings of low water/cement ratio. As the concrete sets it is tamped, vibrated, and if desired impressed with a suface pattern. Grooves and other depressions may be formed on the underside of the casting by laying cores on the bed in the same manner as the strips B. When the concrete has set the separating strips B are machined away and the edges of the castings, e.g. panels, are machined, e.g. grooved so that the joint between two panels is tubular, allowing grouting material to be forced in through a tube, the machine tools for these purposes being mounted on a carriage which runs on one set of rails. The castings may also be given a finishing coat. A carriage P, running on the upper set of rails Z, carries suction pads R which lift the castings from the bed and hold them up while they are cleaned by revolving brushes H on a carriage O running on the middle rails Y. The truck O also carries suction means for removing sand and other particles into receptacles, for re-use. The carriage O then moves clear and a conveyer truck M moves below the panels which are lowered on to it. Reinforcement may be incorporated by depositing a layer of concrete about one-third the required thickness from a hopper on a first carriage, laying thereon reinforcement paid out under tension from a roll on a second carriage, and laying a final layer of concrete from a hopper on a third carriage. Emulsified bitumen may be laid instead of, or with, the reinforcement. For making cavities in the casting the first concrete-laying carriage is followed by a carriage carrying an air compressor, and a revolving drum wound with rubber tubes is located at a suitable place, e.g. in a pit. The tubes are inflated from one end and their other ends are fitted with nipples with reducing bores, and at intervals along their length, thus reducing the pressure by stages and enabling the tubes to be drawn easily through the concrete.

Abstract: 258,675. Bourassa, J. C. E. June 27, 1926. Cylinder machines; inking- apparatus; bed - reciprocating appatatus. - A continuousrevolution printing-machine is constructed so that the travel of the bed is reduced by arranging the ink-applying rollers to reciprocate in the opposite direction to the bed, and to assume finally a position under the impression cylinder which is raised from the bed after the printing operation. The bed 13 and the inking-roller frame 34 are reciprocated in opposite directions by a threaded shaft 30 formed with continuous threads engaging shoes 31, 32 on the bed and frame respectively. The impression cylinder 12 is shown in the position to commence printing in Fig. 4, and as the bed 13 moves to the left to print, the inking-rollers move to the right over the distributing-table 13x, and then over the forme carried by the lower part of the bed 13. The printing finishes, and the cylinder 12 rises before the inking-rollers move right across the forme and assume a position under the cylinder 12. The cylinder 12 is mounted in rising and falling bearings 10, and is constantly in gear with a gear 24 on the shaft 16 of the cam 15 which raises and lowers the cylinder. The cylinder 12 has a gear 25 in mesh with a gear 26 geared to the gear 24, and the gear 26 is mounted in links 28, 29 pivoted to the axes of the gears 24, 25. The gears 24, 25, 26 are so arranged that the cylinder 12 rises at the same rate as the driving-gear 24 rotates, so that the cylinder 12 remains substantially stationary for a short period, and during this period is is fed with a sheet. To reduce the friction of the bed 13 and carriage 34 antifriction rollers are used which are reciprocated by a continuouslythreaded shaft 30<a> integral with the shaft 30; the shaft 30 is driven by worm gearing from the shaft 38, and is held in its bearings in the frame bv nuts 30b and locknuts 30<c>, and the thrust is taken by antifriction bearings 30d. Tripping-arrangements.-The cylinder bearings 10 are connected by rods 17 to sliding blocks 18, 19 at each end of the cylinder, and rollers 21, 23 on the blocks are operated on by cams 15 on a shaft 16 geared to the driving-shaft 38. The cylinder is thus raised for the inking-rollers to move beneath it.
