Title: Apparatus for handling magnetic cores having an asymmetrically located centre of gravity
IPC: B23Q7/12
Filed: 1966-04-28
Abstract: 1,137,755. Orientating articles; jigging conveyers. RAMSEY ENG. CO. 28 April, 1966 [18 Aug., 1965], No. 18702/66. Headings B8A and B8S. In apparatus for handling generally flat elongated magnetic cores 12, Fig. 6, each having an asymmetrically located centre of gravity along its longitudinal axis and having a hole 22 in its heavier end portion, the cores are advanced in end-to-end relationship along a surface 46 having an opening 54 and a tongue 56 projecting from the approach edge of the opening, so that if a core reaches the opening with its heavier end portion leading, as shown in Fig. 6, it drops through the opening but if its lighter end portion is leading, Fig. 9 (not shown), it passes over the opening. The apparatus comprises a vibratory bowl 32, Fig. 1, having a spiral track 36 leading to the surface 46, a depression (38), Fig. 3 (not shown), being provided in the track 36 to return cores not orientated in end-to-end relationship back to the bowl. Deflectors (48), (62) ensure only a single line of cores by diverting any piled-up cores back to the bowl. Further openings (54A), (54B), (54C), similar to opening 54, are provided to ensure that only correctly orientated cores continue along the surface 46 to a shoot 66 leading down to a core locator assembly 68. The assembly 68 comprises arms 76, 78, Fig. 11, which are pivoted at 80, are urged towards each other by springs 88 and carry fingers 82, the latter being notched to provide a core holding pocket 86, see also Fig. 13 (not shown). The arms 76, 78 carry cam followers (92), Fig. 12 (not shown), for co-operation with a cam 94 carried on a driven shaft 96, for opening the fingers 82. While each core is in the pocket 86 it is engaged by conductor probes 102, 104, Fig. 14, which are carried by a slidable arm 106 loaded by a spring (118) and carrying a cam follower (114) which co-operates with a cam 116 on the shaft 96, the probes being moved towards and away from the cores. A spring finger 120 is carried by a system of levers 124, 122, 130, 132 carrying a cam follower 138 which co-operates with a cam 140 on the shaft 96, the finger 120 being pressed against the core above that being tested by the probes 102, 104 to retain the cores in the shoot 66 when the fingers 82 are open. The probes 102, 104 lead to magnet testing equipment and after a core has been tested the fingers 82 are opened to drop the core down a tube 142 on to a pivoted deflecting vane 144 the position of which is determined by a signal from the testing equipment so that it deflects the core into an " accept " receptacle 150 or a " reject " receptacle 152.

Title: Improved process and apparatus for the manufacture of artificial films and filaments
IPC: D01D5/04
Filed: 1931-06-29
Abstract: <PICT:0365484/IV/1> Artificial filaments and films are made by dry-spinning a solution of a cellulose derivative or other like material into a vacuum chamber, the product being led out of the chamber through a liquid column of sufficient height to balance the pressure difference between the evacuated chamber and the outer atmosphere.  The filaments or films undergoing evaporation may be carried on an endless band while a current of air or gas is led along said band. The evaporated solvent may be recovered, if desired, by condensation in a cold chamber connected with the evacuated chamber. In the Figure, an endless ribbon b supported by rollers c moves within the chamber a.  A nozzle e discharges the spinning solution on to the ribbon b moving in a direction opposite to that of a current of drying atmosphere which enters the chamber a at g, passes in the direction of the arrows, and leaves at f.  The film l leaves the ribbon b at m and passes out of the chamber by way of a mercury-filled tube n connected with a cup o.  In Fig. 2 (not shown) the film l is supported during its descent through the mercury column by means of the endless ribbon b, and after separation of the film outside the chamber, the ribbon is returned.

Filed: 1960-05-31
Abstract: 877,048. Coin-freed ball games. PFLUGMANN, G. May 31, 1960 [June 4, 1959], No. 19169/60. Class 27 [Also in Group XV] In table football apparatus including shoots 15 for loading balls from the goals and a tube 19 for returning them to the playing surface, this being effected by a jet of air induced at nozzle 18 through tube 17 by pressing a bellows 16, coinfreed mechanism controls the duration of play or the number of balls supplied up tube 19. As shown in Figs. 4 and 7, balls from shoots 15 enter a common tube 29 discharging to the upper surface of manually-rotatable disc 23 which has a ring of apertures 28 each to receive one ball and closed at the lower end by a stationary plate 30. This plate has one aperture 31 aligned with jet 18 and tube 19 and rotation of disc 23 carries a ball from tube 29 to drop into aperture 31 and be discharged up tube 19. After a predetermined number of actuations of the disc 23 (i.e. of goals scored) a projection 48 on the disc engages an abutment 40 on lever 36 to move it so that one end 37 enters a slot 38 in tube 19 to block it and prevent further ball feed. Insertion of a coin 45 through slot 46 causes it to drop down guide 44 and fall on cam face 43 on the other end of lever 36, the coin's weight swinging the lever to withdraw end 37 from slot 38 and allow feed of a further set of balls. As shown in Fig. 9, lever 36 is restored to inoperative position by pushing in rod 50 which, acting through a coin 45 if inserted, pivots a lever 54 the lower end of which engages lever 36. In a modification, Figs. 10-14 (not shown), pushing in rod 50 acts through a coin, if inserted, to pivot a stop out of tube 19 and to wind a timer, the stop being held out by a detent which is relapsed by the timer after a predetermined time has elapsed. In this modification, shoots 15 discharge directly into the lower end of tube 19 above jet 18. As shown in Figs. 15, 16, the shoots 15 end in a common tube 29 from the lower end of which they are transferred to nozzle 18 under tube 19 by a transfer slide 69 urged to the right, Fig. 15, by a spring and carried to the left to pick up another ball by movement of an arm 89 depending from a channel 85. One wall 86 of this channel has pivoted at 88 a bar 87 and a rod 78 fitted with a push-button 77 carries a block 81 provided with a coin-groove 82 adjacent the remote end of bar 87. Thus if a coin 45 be in groove 82, pushing of button 77 will move arm 89 through the medium of block 81, the coin, arm 87 and channel 85 so that another ball is picked up. Channel 85 carries a ratchet 92 rotated one step each time button 77 is pushed by a stationary pawl 93. When the predetermined number of balls has been fed a pin 98 on the ratchet engages a projection 99 on bar 87 to lift it and thus release the coin 45 and break the coupling between the button 77 and the ball feed until another coin has been inserted.
