Title: Improvements in or relating to method and apparatus for separating torn tobacco leaves
IPC: A24B5/10
Filed: 1957-10-15
Abstract: 838,321. Separating torn tobacco leaves from stems, grit &c. AMERICAN MACHINE & FOUNDRY CO. Oct. 15, 1957 [Nov. 19, 1956], No. 32197/57. Class 117. Torn tobacco leaf lamina are separated from stem, dust, grit or lint by passing the airborne mixture along channels, screens and cyclone separators. The mixture is on a conveyer belt where the air current floats the lighter leaf parts, through a separating channel 3 where the stem parts fall on to a conveyer 21 which carries them away for reprocessing. A stream of air from inlets 7 carries the leaf up a channel 9 to an expansion chamber 11 where any heavier particles fall down to 17. Meantime the leaf is carried along to a curved solid wall along which the leaf and dust lies, until the leaf only falls to a discharge chamber 38 while the heavier dust &c. pass through an orifice 31 to a screen 53 to a rotor which carries it away. Meantime the cleaned leaf falls from 38 through a rotary air sealing outlet to a conveyer. At screen 53 some of the tobacco may pass through to a bank of cyclone filters 57 to remove dust which passes into a chamber 49 from which a bottom worm 59 carries the dust away. Fans 63 provide the suction and forced draught. The dust and lint from the cyclone filters fall down in a downward air current from the cyclones to a collecting drawer 73.

Title: Improvements in or relating to treasury note cabinets
IPC: G07D11/00
Filed: 1923-12-29
Abstract: 231,239. Warren, A., and Solomon, S. N. Dec. 29, 1923. Money-delivering apparatus, - Relates to Treasury note cabinets of the kind described in Specification 183,926, wherein notes, inserted through a slot, are held exposed to view between a pair of frames, the actuation of an operating lever on the insertion of a second note, passing the first note to a till, and releasing a change drawer furnished with trays containing change to be given for the second note. Means are provided to prevent more than one use of one) only of the change drawers for each actuation of the operating lever, to indicate which of the change drawers has last been used, and to lock the mechanism when not in use. A ratchet rack with oppositely-cut sets of teeth l, l<1> is carried by each of the change drawers c, c<1>, and the tails of correspondingly reversed pawls m, n, pivotally mounted above the racks l, l<1>, engage opposite sides of a depending lever o, which is actuated, through linkage, by a spring-controlled rocking- arm r. On the actuation of the operating lever e<2>, a pawl s thereon engages the arm x, bifurcated to prevent disengagement before a full stroke has been obtained, and raises the pawl m from the rack thereby permitting outward movement of the change drawer, the pawl n being also moved by the lever o to engage the racks l<1> and prevent closing of the drawer before it has been fully drawn out. When released, the operating handle is returned to its normal position by a spring, thereby releasing the arm r which raises the pawl u to enable the change drawer to be pushed in. To indicate which change drawer has been last operated, a pin w on the drawer pulled out, engages the edge of a curved cam face on a pivoted lever x, rocking an arm x<2>, pivoted centrally of the cabinet and carrying a T-shaped indicator. To lock one drawer against movement while the other drawer is open, a cam v on the open drawer is adapted to engage one end of a bolt t and push the bolt endwise into a hole in the opposite drawer. Springs u return the bolt to its normal central position when the drawer is closed. A bolt, actuated by a key kept by the operator, may be shot across the lever e<2> when the mechanism is out of use. Guide-plates 5, Fig. 1, are fitted to keep the exhibited notes centralized, and the drawers c, c<1> move on rollers 6. An annunciator bell is operated by an arm and trigger mechanism from the frame-actuating slide j.

Title: Directional data transfer apparatus
IPC: G11C19/00
Filed: 1957-10-18
Abstract: 867,997. Electric data-storage stepping registers. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Oct. 18, 1957 [Oct. 18, 1956], No. 32592/57. Class 106 (1). A stepping register capable of moving a binary number contained therein in either direction comprises a sequence of storage units each having an input and an output, each output being connected to the input of the succeeding unit through one of a first series of gates and to the input of the preceding unit through one of a second set of gates, the first and second sets of gates responding to first and second signals to transfer the data in one direction or the other. Each of the storage units comprises a pair of series-connected magnetic amplifiers 11, 12; 13, 14; 15, 16 and 17, 18, each of which stores a binary digit in a magnetic core until a stepping pulse causes the digit to pass to the next amplifier. The digit is stored in each amplifier for half a bit period, the two amplifiers being pulsed alternately at this frequency. A recirculation loop is provided for each pair of amplifiers having a gate 41, 42, 43 and 44. When these gates are opened by a third signal on terminal 45, the data in the unit merely passes from one to the other of the two amplifiers. When the register is to receive a binary number with the least significant digit leading, the first set of gates 21, 22, 23, 24, 25 are opened by a signal on terminal 19 so that the number enters from the " LS IN " terminal 20 and passes stage by stage into the units of the register. If the number is to be recirculated the gate 55 is opened by a signal from terminal 56 and the leading digit passes from unit 17, 18 to unit 11, 12 with the others following. If the number is to be read out with the most significant digit leading on MS OUT terminal 52 the second or reversing signal is applied to terminal 29 to open the second set of gates 32, 33, 34 and 35. This causes the least significant digit in unit 17, 18 to pass through gate 32, unit 15, 16, gate 33, gate 34, unit 13, 14, gate 35, unit 11, 12 to terminal 52. The other digits in the other units precede the least significant digit so that the order is reversed. The number may be read into the register with the most significant digit leading on terminal 30 and read out in the same or reversed order on terminals 52 and 51, the operation being the reverse of that described above. More than four stages may be provided as indicated by the dotted lines. Specification 840,050 is referred to.
