Abstract: 917,443. Extruding tubes. DU PONT DE NEMOURS & CO., E. I. May 5, 1961 [May 6, 1960(2)], No. 16348/61. Class 87(2). In a process for extruding and biaxially orientating tubes of thermoplastic polymers such as polyamides, polyoxymethylenes, polyethylenes, &c., a cooled mandrel is used in a crosshead. In the apparatus illustrated granulated material is fed from hopper 80 via an extrusion screw to crosshead 79 and extruded round mandrell 81 in the form of a tube 87. The inner part of mandrel 81 is heated to keep the material molten while the end of mandrel 81 at the extrusion orifice is water cooled so that the inner part of the tube is formed first in order to obtain a smooth inner surface. Rolls 84 draw off the tube which may be sized by a die of polytetrafluroethylene (not shown) while still molten on the outer surface to give a smooth outer surface. The partly crystalline material may then be biaxially orientated to improve its strength by passing over flared mandrel 85 rollers 88 compressing and extending tube 87 to tube 86 being driven by epicyclic gear system 89 by rotation of shaft 90. Cooling water for mandrels 81,85 is supplied by tube 82 and flows out of the apparatus via product tube 86. Specification 770,717 and U.S.A. Specification 2,768,994 are referred to.

Title: Improvements in or relating to mechanism for coin-freed gas meters
IPC: G07F15/08
Filed: 1926-07-01
Abstract: 268,196. Smith, E. W., and Smith Meters, Ltd. July 1, 1926 Gas, supplying by meter.-In a coin-freed gas meter, part of the transmission gear is frictionally mounted on a split boss, which is rotatable by the gear but which can be rotated in one direction to zeorize the mechanism by a key applied to a ratchet-like end on the boss. The invention is shown applied to mechanism having a variable gear, for use with different coins, which consists of two toothed wheels reversible on their axis, as described in Specification 222,787. The usual threaded spindle c has a nut e provided with a split boss 3 on which a pair of reversible wheels 1, 2 is fitted. The meter rotates the nut e to close the valve through a worm f, a worm wheel, and a double wheel g, h which meshes with one of the wheels 1, 2. The valve may be closed independently of the meter mechanism by a key 4 having a ratchet-like end 5 to engage corresponding end 6 on the boss 3 and rotate the nut e. The split boss prevents the mechanism from being damaged in the event of the valve leaking or too many coins being inserted.

The attitude of paddles 5, Fig. 1, pushing articles into bags 100, is controlled at the arcuate ends of their endless paths by devices which rotate unidirectionally. The paddles 5, Fig. 4, on arms 6, pivot about a shaft 7 which is attached to a pair of endless chains 9 and 11. The end of each shaft 7, adjacent the chain 11, has a crank-arm 29 with a pair of rollers 30 which engage guides 31 to control the attitude of the paddles along the straight stretches and partially at the arcuate stretch adjacent the bagging end of the machine, Fig. 8. At this end of the machine, a rotor 38 engages a blade 40 on the crank arm 29, and hence is levered through a right-angle causing the paddle 5 to similarly change its orientation, and retract from the filled bag. At the article feed end of the machine, Fig. 4, an elongated spindle 37 of one of the rollers 30 is engaged by the end of an arm 32 which rotates off-centre of the centre of the sprocket 15 of chain 11, hence causing the shaft 7 to rotate as it progresses around the arcuate end of the chain, so that the paddle maintains its orientation. The bags 100 can be opened by air jets and are held open by a reciprocating spreader 24.

[Also in Group XXXVI] In a liquid level gauge (see Group XXXVI), a valve relay circuit is controlled by variation in the capacitance of a pair of electrodes. In Fig. 2 of the Provisional Specification the upper plates of capacitors 28, 29 are formed by the sensitive electrodes and are connected in a bridge circuit fed from an electroncoupled oscillator 22 via lead 12. When the bridge is unbalanced by the approaching level the output is taken from the resonant circuit 31, rectified at 16 and fed via lead 12 to operate a valve relay circuit 17, 18. Operation of relay 18 energizes lamp 19. The D.C. voltage developed by the lamp current in lead 25, provides positive feedback for valve 17 and hence more definite relay operation. Fig. 1 (not shown) of the Complete Specification relates to a relay circuit in which the bridge containing the sensitive electrodes is connected in the feedback path of an amplifier which becomes oscillatory when the bridge is unbalanced.
