Title: Article selection system
IPC: G06K21/00
Filed: 1968-08-01
Abstract: 1,242,230. Selecting cards &c. OK. PARTNERSHIP. 1 Aug., 1968 [4 Aug., 1967], No. 36837/68. Heading G4M. Cards 10, Fig. 6, having location notches 16 of which selected ones are jointed as at 15-3 by removal of the intervening tooth 17, are selected by operation of selector bars 53 into engagement with notches 16, and displacement by one tooth pitch of cards such as 10<SP>1</SP> corresponding to the operated selector bars, non-selected cards being restrained from movement e.g. by a locking bar 25 before retraction of selector bars 53 and further withdrawal of the selected cards. Selector bars 53, Fig. 17, may be raised by an array of solenoids 109 mounted on a carriage 108 which is driven by an escapement mechanism to set groups of bars 53 as successive entries are made on a keyboard. Each bar 53 when moved to the left by crank 127 rides up on to rods 59 and is raised above the surface of a card support platen. The bars are reset by a common solenoid 170. Selection operation.-After setting the selector bars 53, Fig. 10, a motor is energized to drive a cam 226 and an associated switch cam through one revolution, the cams controlling the sequential operation of the card withdrawing mechanism and the locking bar. Withdrawing mechanism.-Front panel 201 includes a bar 72 with a camming lip 73, Fig. 6, which assists in holding the coded edge of the cards 10 on the support platen. Panel 201 also carries a magnet 77 which co-operates with magnetic chips attached to the card corners, the sinuous outline reducing the tendency for the corners to bend and tear. Initial withdrawal by the width of one notch 16 is effected by cranks 231 which are pivoted by cam 226, the ends of cranks 231 bearing on panel 201 to move it evenly along its length. Selected cards are partially withdrawn by attraction to magnet 77. A cam raises the locking bar through linkage (not shown), and camming wheel 240 then engages plate 241 to push the front panel 201 further out and thus complete withdrawal of the selected cards. Modifications.-A lipped positioning bar cooperating with an additional notch in the other vertical edge of the cards, similar to bar 72 and notch 40, may be used to press down the other end of the card coded edges, Fig. 25 (not shown), or a partial, sloping cover (85), Fig. 1 (not shown), serves the same purpose. Both horizontal edges of the cards may be coded, and one or more compartments between separators may be kept empty for sequential selection on the two edges. Withdrawal of selected cards may be aided by an additional bar engaging a notch in the coded edge of the cards, or partial withdrawal may be effected by moving the selector bars whilst completion of the withdrawal may be effected by movement of magnet 77 or locking bar 54. A further magnet and magnetic chip on the other side of the cards may be used instead of a locking bar.

Filed: 1975-09-08
Abstract: The copier contains a mask (21) in order during copying of a copying original composed of a plurality of parts to cover the edges between the parts of the originals, so that no light impinges from the edge regions of the original onto the photosensitive recording carrier. As a result, the copy produced on the recording carrier is prevented from having undesired dark regions or lines. The mask can be moved by means of a control device (32) from its effective position into an ineffective position, in order to be able to copy individual copying originals in addition to the copying originals consisting of a plurality of parts. <IMAGE>

An apparatus for contacting mutually immiscible liquids comprises a helical coil having a constriction in one of its turns dividing it into an upstream and a downstream portion, said upstream portion containing a plurality of individual contact members. As shown in Fig. 2, the coil is preferably in the form of a rising helix 14 and the contact bodies 23 are located therein by means of constrictions 24. The bodies are preferably in the form of small hollow glass cylinders and the coil is mounted in a jacket through which a temperature-controlled fluid is passed. Fig. 4 illustrates an analysis system which may be used for monitoring the tetraethyl lead content of the atmosphere. The air is bubbled through water which is passed into tube 44 of a flexible tube pump 40 and meets streams of segmentizing air or other fluid and a diluent at 46. The segmentized stream passes to mixing coil 52 and thereafter the segmentizing fluid is removed through line 58 while a non- miscible solvent for tetraethyl lead (chloroform) containing dithizone is added to the stream at 62. The mixture is passed through the contacting device 10 where the tetraethyl lead is extracted into the chloroform and produces a colour with the dithizone. The mixture passes to separator 12, aqueous liquid being removed at 38 and the chloroform layer being withdrawn through line 42 by means of the pump and passed to the colorimeter 72.

Abstract: 1,199,181. Treating grain. JAYBEE ENG. PTY. Ltd. 11 Aug., 1967 [15 Aug., 1966], No. 36925/67. Heading A2Q. A machine for milling or skinning grain (e.g. wheat and rice) comprises a rotatable substantially horizontal drum 3 in which are mounted coaxial discs 4 each disc having an abrasive coating on one or both faces thereof. In use the grain is caused to move across the discs so that the outer surface of the grain is removed therefrom without pressure being applied thereto. The drum 3 and discs 4 may be rotated at different speeds and in different directions. The inside of the drum 3 may be provided with abrasive surfaces or ribs. In the embodiment shown, the drum 3 comprises perforated sections 9 and gates 25. Gates 25 comprise apertured plates 32, 33, plate 33 being movable to bring the apertures into or out of alignment. The machine comprises air pipe 43, exhaust pipe 45 and two screw conveyers 50. In use grain is fed batchwise by screw feed 48 to drum 3. The powder formed during the processing of the grain in drum 3, is discharged through the apertures in sections 9 and is conveyed away by conveyers 50 rotating in one direction. The apertures in sections 9 are kept clear by the air blast from pipe 43. When the grain has been processed a gate 25 is opened by a hydraulic piston actuated roller 40 moving plate 33 to align the apertures and the grain is discharged to conveyers 50 which are now rotating in the opposite direction. The gate 25 is closed by fixed roller 42 contacting plate 33. In other embodiments the grain may be fed to and discharged from the drum along the whole length thereof through a gate 25 or the grain may be fed continuously to one end of the drum and continuously discharged from the other end of the drum

Abstract: 876,790. Mounting electrical equipment. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 20, 1958 [Nov. 22, 1957], No. 37341/58. Class 37. A circuit card assembly includes a frame, adapted to receive at least one circuit card, which is pivoted at one corner for movement in the plane of the card, and a frameretaining means which holds the frame in either a normal or a withdrawn position. As shown in Fig. 1, a number of card-carrying frames 1, 2, 3, 4 are pivoted to move between a normal position 2, 4 and a withdrawn position 1, 3. Retaining means 5, 6 are provided which can rotate between the positions shown and a normal position in which the arms 5, 6 are vertical (Fig. 3, not shown), rotation being controlled by pulleys which pass over pulley wheels 7-10 to ensure that both retaining means move together.
