Title: Improvements in document feeding apparatus
IPC: G06K13/107
Filed: 1963-02-13
Abstract: 999,011. Feeding and delivering sheets. GENERAL ELECTRIC CO. Feb. 13, 1963 [April 18, 1962], No. 5919/63. Headings B6B and B6H. [Also in Division G4] A document feeding apparatus for feeding the end document of a stack to conveying means, in which the stack is urged in the direction of a continuously running endless separator belt extending from a region adjacent the middle of the lengthwise dimension of the end document to a region adjacent the leading end thereof, includes a movable gate means movable between a closed position between the belt and end document, to hold the end document away from the belt, and an open position in which the gate is retracted to permit the belt to contact the end document, the gate means pivoting in response to a command signal. Pile tables and supports.-The stack 12 is supported on edge by a back-plate 13 continuously urged towards a front plate 14. Separators.-A pivoted gate 20 having a plurality of fingers 22 passing through slots in the plate 14, normally engages the front of the stack to hold the front sheet 15 away from three spaced friction separating belts 17. When the gate is pivoted away from the stack in response to a command signal, the front sheet is pressed against the belts. The leading edge of the front sheet is lifted above the front edge of the magazine 23 by suction means 70. Subsequent movement of the gate is controlled by a photo-electric cell 42. The latter emits a first signal on sensing, the leading edge of the front sheet to reset the gate in the position shown in Fig. 3, and hold the next sheet in the stack away from the belts 17. Said cell emits a second signal on sensing, the trailing edge of the front sheet, to pivot the gate away from the stack and permit feeding of said next sheet. Feeding of the sheets continues until the command signal is interrupted. Sheet carriers and forwarders.-The sheets are advanced to a reading station 43 by a continuously moving endless belt 25 and co-operating rollers 45-47 and stationary guide 51. Delivery.-The sheets are fed from the reading station by said belt 25 and further co-operating rollers 48-50 and stationary guides 52, 53 and fed around a driven pulley by a co-operating belt 55. The stack is held between an overlying stationary plate 63 and base-plate 62, the latter receding as the stack grows.

IPC: B65D83/06
Filed: 1970-02-06
Abstract: 1,262,242. Powder dispenser. FABERGE Inc. 6 Feb., 1970, No. 5930/70. Heading B2F. A shaker top dispenser container, as shown, is made up of a container 20, an inner dome member 11 and an outer dome member 15. The inner dome member 11 has a polar opening 11b, concentric with the polar axis x-x, surrounded by circular steps 12 and 13. Shaker holes 11c are arranged in a circle on step 12, the axes of the holes being parallel to the polar axis. Outer dome 15 is permanently mixed onto inner dome 11 by a snap-in connection of flanges 12a and 16. The rotation of dome 15 is controlled by a pair of diametrically positioned recesses (14) (Fig. 4, not shown) in lower step 13, into which a pair of fins 19 extend, from the inner surface of dome 15. The recesses (14) are positioned with respect to shaker holes 11c, and fins 19 with respect to shaker holes 15c, so that the holes are in register with the fins abut one of the end walls 14a of each recess, and out of register when the fins abut the opposite end walls. The bottom of each recess is provided with a raised boss 14b, so that the edge 19a of each fin engages and rides on the boss when outer dome 15 is rotated, which prevents accidental rotation between the open and closed positions. However, while lower step 13 can be eliminated, its retention is useful as an anti-sifting device, as its engagement with flange (18) (Fig. 6 not shown) prevents powder sifting through shaker holes 11c, between dome members 11 and 15, and out at the bottom of dome member 15.

Filed: 1954-05-06
Abstract: 772,431. Supply systems for welding arcs. E.M.F. ELECTRIC CO. PROPRIETARY, Ltd. May 6, 1954 [Aug. 10, 1953], No. 6458/56. Divided out of 772,430, (Group XI]. Class 38 (4). [Also in Group XI] Inductive impedance F and resistive impedance G connected to welding electrodes K, J enable currents of differing phase to be produced in the electrodes by a single-phase transformer C. Since both electrodes are supplied from the same transformer winding D, the inter-electrode arc which undesirably persists with normal twophase welding apparatus is extinguished at the same time as the main arcs when the electrodes are withdrawn from the work E. Switches I enable the value of resistor G to be adjusted, and the inductive impedance F may be varied by movement of its core with respect to its winding. The phase difference may be further increased by the provision of capacitors, or capacitors in series with resistors, connected in parallel with the resistive impedance. The inductive impedance may be incorporated in the transformer.
