IPC: C30B11/10
Filed: 1955-05-17
Abstract: 798,818. Gems. GENERAL ELECTRIC CO., Ltd. May 17, 1956 [May 17. 1955], No. 14241/55. Addition to 697,419. Class 43 The apparatus described in the parent Specification for making synthetic gems from alumina powder is provided with a modified distributer which includes at least one passage adapted to connect the primary powder-conveying duct 7a with one of the secondary ducts 21 leading to the furnace 3, means being provided for repeatedly moving the distributer intermittently from one to another of a series of positions such that the, or each, passage 15 connects with all of the secondary ducts in turn. In the example, the distributer is provided with six passages 15 and is rotated intermittently by an electromagnetic device to bring each of the passages, in turn, to connect with each of six secondary ducts 21. The distributer, which is housed within a cylindrical casing 8 of non-magnetic material, comprises a rectangular block 9 of magnetic material with end faces curved convexly to fit into the contour of the surrounding casing 8. The under portion of the block 9 has a conical cavity 10 which is coaxial with the powder duct 7a and within which is brazed a conical member 14 formed with six slot-like passages 15 with their upper ends converging into a central space 16 and their lower ends providing six equally spaced openings 17 in the base of the conical member 14, adjacent to and parallel with the base of the casing 8 and also in close proximity to the upper ends of the six secondary ducts 21. A frusto-conical cavity 18 in the base of the block 9 forms a housing for a tapered bearing 20 for a supporting shaft about which the block can rotate, an upper conical bearing being provided by an axially apertured bush 11 seated in a recess in the upper face of the block to receive an axially apertured conical shaft 12 mounted on a flexible diaphragm 13 disposed across the top end of the cylindrical member 8. Rotation of the distribter is effected by the energization of six electromagnets 30 spaced equally around the cylinder 8 with one pole 31 of each extending just through the wall of the cylinder, the magnets being wired in pairs to produce three magnetic fields at 120 degrees apart. The pairs of windings are energized in turn at predetermined intervals through a relay mechanism driven by a motor (not shown) which also operates a tapping-hammer provided for striking a dispenser which releases the alumina powder at the upper end of the tube 7, as in the parent Specification. As each pair of associated magnets 30 is energized the block 9 aligns with the field thereof, and remains in such position for a period of time during which each of the six passages 15 in the distributor is positioned above a corresponding duct 21 leading to the furnace 3. A light-sensitive device similar to that of Specification 633,118 is provided for controlling the movement of a motor which moves the rods 27 of synthetic corundum downwardly as they build up.

Title: Improvements in or relating to means for separating flat sheets, cards, tallies, cheques, documents or the like
IPC: G06K21/04
Filed: 1944-08-03
Abstract: 592,850. Statistical apparatus. McKEOWN, J. L. Aug. 3, 1944, No. 14809. [Class 106 (i)] Relates to card index systems or the like in which cards are perforated along the edges and numbers are recorded upon them by opening out certain of the perforations to the edge of the,cards, a " condensed code " being used in which, e.g. each digit is represented by one or two out of four holes representing the numbers 7, 4, 2 and 1. According to the invention means for selecting cards comprises a plurality of needles or the like and holder means in which the needles are spaced so that a single needle or a plurality spaced in accordance with each possible digit can be presented to the stack of cards. Fig. 1 shows a card in which perforations have been opened out to represent the number 6387. A holder 1, Fig. 2, carries four long needles 2, 3, 4, 5, arranged upon it so that the distance between needles 2 and 3 corresponds with the distance between adjacent perforations on the card, the distance between needles 3 and 4 is equivalent to that between, e.g. the numbers 7 and 2 on the card, and the distance between 4 and 5 is equivalent to that between, e.g. the numbers 7 and 1 on the card. Thus, pairs of needles can be passed through a stack of cards to select the " compound " digits, and then single needles 4 or 5 can be employed to select digits 7, 4, 2 or 1. In another embodiment needles are mounted in pairs at equal distances from the centre of the holder so that the latter can be rotatably mounted on a pedestal or the like slidable laterally. In another embodiment (Figs. 8 and 9) four needles 19 are individually slidable in a block 18 by handles 23 running in slots 20 communicating with the bores containing the needles. The block 18 rests on pedestals 24 which are slidable laterally to bring the four needles opposite any desired field in the card. A handle 25 secured to the block 18 is used for lifting the stack of cards after the appropriate needles have been passed through. Upon shaking, the selected cards will fall down from the stack. In a further embodiment a compressed air jack (Fig. 11) is employed for raising the stack of cards and the shaking is performed automatically by a valve 40 which is opened by a flange 39 when the piston reaches the top of its stroke. The loss of pressure, assisted by a spring 42, causes the piston to drop somewhat, whereupon the valve closes and the piston is again raised, and so on. A needle valve (not shown) is provided to adjust the periodicity of the reciprocations. The piston rod 31 may be attached to the lifting handle 25 (Fig. 9) but, in another embodiment a number of pneumatic jacks operate the vertical pin 28 sliding in guideways in the pedestals 24.
