Abstract: 701,427. Feeding cartons by vacuum holding devices. JAGENBERG-WERKE AKT.-GES. Feb. 26, 1952 [March 6, 1951], No. 4997/52. Class 117. In a device for separating, opening, and feeding in a reversed flattened condition tubular cartons which are first packed in flattened condition in a holder, the flattened carton is partially pushed out from the holder and is then engaged. removed from the holder and opened by continuously rotating suction members engaging with opposite sides of the flattened carton. As shown, a carton 2 is partially removed from the holder 1 by a reciprocating pusher 3, or alternatively by a feeding pin continuously circulating on a chain or the like or on a cylinder, Fig, 5 (not shown). A continuously rotating roller 4 provided with vacuum cups 6 then co-operates with a roller 5 to withdraw the carton entirely from the holder, and carries it into the path off a continuously rotating suction member 10. The carton 2 engaged on either side by the suction members 6, 10, is opened during the subsequent rotation of the suction members, the member 10 being provided with a movable nozzle which adapts itself to the position of the carton surface held against it. At this point the suction is removed from the nozzle 10, releasing the carton, and an opposite face of the carton is brought against a member 13 which during subsequent movement of the vacuum cup 6 turns the carton over into its reversed flattened condition, when it is gripped by a conveying roll 14 co-operating with the cylinder 4, the suction is removed from the cup 6, and the reflattened carton is fed in the direction of the continuously running chain conveyer 15. To ensure the delivery of the carton to the chain conveyer, equally spaced spring-loaded radial pins are provided on the cylinder 4 which are brought into action as by an eccentric on the shaft 8 to act against the rear edge of the carton when it is no longer gripped by the roller 14.

Abstract: 1,105,702. Educational appliance. GENERAL ELECTRIC CO. Ltd., T. J. CANNON, W. R. GODDEN, I. D. MACLEOD and R. D. NIXON. 7 Feb., 1966 [8 Feb., 1965], No. 5370/65. Heading G5G. [Also in Divisions F2 and G2] A visual teaching machine has a film transport mechanism by which a selected number of film frames may be wound on, and mechanical means for storing an indication of said number, the film then being wound back a number of frames in dependence upon the stored indication so that the previously viewed frame may be returned to. Film is wound from spool 8, through gate 5, and into open receptacle 26 by driving sprocket 14, selected frames being projected by lamp 2 and lenses 6, 7, on to a screen in the projection lid, via mirror 9. Guide 16 holds the film on to sprocket 14 and is retractable for film loading. The transport mechanism includes a clutch, Fig. 1 (not shown), whose driven member (45) is coupled to sprocket (14) and whose driving member (46) is driven by a lost-motion coupling to a position displaced from a datum position and corresponding to the extent of film wound on. Trip member (62) operates during the lost motion to disengage the clutch momentarily and so permit member (46) to return to its datum position before driving the member (45), this displaced position of member (46) then providing an indicaton of the extent of the preceding film wind-on at any time. Sprocket (14) rotates against a click-stop engagement of eight-toothed detent wheel (35) on sprocket shaft (15) with a wheel carried on arm (37) pivoted at (38), each click corresponding to one film frame. Shaft (15) is driven through bevel gears (34, 42) by shaft (43) on which member (46) freely rotates. Member (45) is locked to shaft (43) and has teeth which are engaged by a tooth (47) on a flange of member (46) which also has an arm (51) by which member (46) is itself driven. Initially, arm (51) rests against stop (54), the datum position, until rotated by engagement with member (52) extending from collar (44) fixed on the actuating shaft (53) which is manually driven by a dialling mechanism by which the number of frames to be advanced is selected. Arm (51) is biased against the rotation of shaft by a spring-loaded cam member (56) mounted on shaft (57). This spring-loading returns member (46) to the datum position when the clutch is dis-engaged by I-shaped trip member (62) which is displaced against member (46) when cam face (67) of member (62) is engaged by the radial extension (68) of member (52). During the dialling operation in which film is being moved, lamp 2 is turned off by a microswitch rotating with shaft (53) and actuated by a cam on shaft (60). If it is desired to return to the previously viewed frame, a lever on shaft (60) is manually turned to rotate shaft (57) and cam member (56) in the direction in which it is biased thereby overcoming the clip-stop mechanism and driving the film back to a position determined by the datum position of the member (46).

Abstract: 764,378. Jaw crushers. HEYMANN, H. G. Feb. 23, 1955 No. 5371/55. Class 59 A method of crushing a piece of material includes the steps of supporting the piece of material at substantially opposite sides thereof and then applying rapidly occurring periodic twisting Squeezes to the piece of material while it is so supported to fracture it into smaller pieces of material capable of free fall, the twisting squeezes being applied to the piece of material in a plane substantially perpendicular to the path of free fall. A jaw crusher for carrying out the method comprises jaws 2, 3 which are oscillated substantially simultaneously in opposite substantially horizontal directions relatively to each other. The jaws are supported by elastic plate members 7 connected to fixed frame members 8 supported on a base 9 and are oscillated by means of connecting rods 10, 11 connected to eccentric socket members 14, 15 mounted on a rotatable shaft 13. The oscillating means cause the jaws to move in curved substantially horizontal paths and in such a way that the jaw surfaces 2a, 3a are nearest to each other when each jaw is at the centre of its path of movement. The jaws converge towards a discharge mouth 5 from which crushed material is carried away on a conveyer 6. In a modification, Fig. 4 (not shown), the path of movement of one of the jaws is inclined to the horizontal.
