Title: Apparatus for feeding lengths of cable coils resting on a distributor conveyor
IPC: B21C47/26
Filed: 1975-05-12
Abstract: 1510863 Feeding coils of cables for cooling purposes BERGMANN KABELWERKE AG 12 May 1975 [18 May 1974] 19819/75 Heading D1T To allow coiled insulated conductors to cool prior to an electric test the insulated conductor 2 is deposited on a first conveyor 4 by a ring laying unit 3 that moves along the conveyor, the conveyor 4 subsequently feeding the coils 5 past a cutting device 8 to a conveyor 7 that can be aligned with any one of a plurality of storage units 9 where the coils are allowed to cool. When cool a further conveyor 18, that can be aligned with any one of the storage units 9, conveys the coils to an inspection track 21' where the sheathed conductors are connected to high tension testing equipment 23. A further conveyor 24' moves the tested coils to a discharge conveyor 25' from whence overhead coiling takes place via means 26', 26". The ring laying unit 3, on completion of a ring laying motion away from the cutter 8, moves back towards the cutter 8 for a further ring laying motion once the conveyor 4 has been emptied onto one of the storage units 9. A dancer truck takes up any slack that would otherwise occur in the supply of the conductor 2 to the ring laying unit 3.

Title: Improvements in and relating to the production of polymers
IPC: B29B9/00
Filed: 1956-06-27
Abstract: <PICT:0824193/IV (a)/1> In a process for the production of powdered polymers or copolymers of ethylene, the molten reaction product which may contain some unreacted monomer, is released from a high to a substantially atmospheric pressure to form a stream with a velocity of at least 100 feet per second, which is then contacted with an inert quenching liquid such as water which comminutes the stream to a powder which may be separated and dried.  Products from processes for the polymerization of ethylene (1) at a pressure of 30,000 pounds per sq. inch using an oxygen catalyst, and (2) in the presence of hydrogen and isopropanol or with a low catalyst concentration to give a low molecular weight waxy polymer, may be passed in an apparatus (Figure) by conduit 10, to a pressure reducing valve assembly 12, provided with a diaphragmtype valve control 24.  The molten product passes through injector passage 38, heated with a steam jacket 44, to the upper end of quenching column 40, around which a plurality of waterquenching ports 48 are radially disposed and intersect to form a screen of quenching fluid.  The reactants are quenched and passed through conduit 40, and the resulting powdered polymer separated from the unreacted monomer and quenching fluid, e.g. by a filter, and dried.  The powdered polymer is suitable for use in powder flame-plating processes.

A forging formed in dies 1, 1<a>, Figs. 1 and 2, having suitably shaped depressions 2 and projections 4, is drilled with inclined holes in a jig 10, Fig. 15, which is so mounted on a pivot 10<a> that it may be secured in oppositely inclined positions in turn by means of a wedge 24 placed between the bottom and the inclined faces 22 of a base piece 21. To drill the ends of the inclined holes with parallel enlargements adapted to receive the ends of the tube limbs, the jig is secured in a vertical position by means of a double wedge 26, Fig. 16, inserted between the bottom of the jig and the base piece 21. The drills are guided by hard steel bushes 17, 28, Figs. 15 and 16 inserted in the cross blocks 8, 27, securing the forging in the jig.

Filed: 1974-05-09
Abstract: 1449373 Exposure control ASAHI KOGAKU KOGYO KK 9 May 1974 [11 May 1973] 20577/74 Heading G2A A camera has an electrical circuit with a switch which can be closed by actuation of the shutter release, and held closed by holding means, which holding means can be released when either the film winding lever is retracted into a closed non- operative position, or when a shutter release lock is unlocked. As shown, the shutter release is a shaft 1 having grooves 1a, 1b, 1c. A release lock member 2 can be rotated from position A, Fig. 1, in which the release may be pressed to actuate the shutter, to position L, in which a spring-loaded lever 12 engages in groove 1a or 1b. If the release has not yet been actuated, lever 12 engages in groove 1b, and prevents said actuation. If the lock is set to position L after actuation of release shaft 1, lever 12 enters groove 1a, and prevents the upward restoring movement of the shaft. In an early stage of depression of shaft 1 it engages a rod 19 which closes a switch 20, which energizes a photometric circuit. A further lever 15, termed a switch holding lever, is spring-loaded towards engagement with shaft 1, and can be actuated by either a projection 2a on lock member 2 or a pin 23 on the film wind lever 3. In the arrangement of Fig. 4 lock member 2 is set to position A, so that lever 12 is pivoted out of engagement with shaft 1. As lever 3 is pivoted in the direction of the arrow into its operative winding position, lever 15 is spring-urged into engagement with shaft 1. When this is depressed, lever 15 latches into groove 1c, and so maintains switch 20 closed. It is opened when lever 3 is pivoted clockwise into its closed position Fig. 8 (not shown), since pin 23 engages and pivots lever 15 anti-clockwise. It is also opened when lock member 2 is rotated into position A. When lever 3 is in its operative position and shaft 1 is not locked, switch 20 is closed by depressing shaft 1 and maintained closed during the subsequent exposure.
