Abstract: 1418859 Current collectors; continuous casting LA SOUDURE ELECTRIQUE AUTOGENE PROCEDES ARCOS SA 21 Dec 1972 [9 Feb 1972] 22231/75 Divided out of 1417710 Heading B3F [Also in Divisions F1 H2 and H5] Electrical contacts comprise a hollow outer contact coaxially surrounding and spaced from an inner contact, the space therebetween being filled with an electroconductive liquid, one of the contacts carrying fins which extend towards the other and which serve as a means whereby one contact can be caused to rotate relatively to the other. A hollow outer contact 114 having inwardly extending cusp-like fins 113 is rotatably mounted by bearings 117 and liquid-tight seals 120 on a fixed hollow inner contact 112 having a hollow shaft 115. Mercury pumped via an inner passage 110 of the shaft 115 into a central cavity of the inner contact 112 is forced through holes 111 inclined to the radii into the space between the contacts, where it impels the fins 113 of the outer contact 114 and then flows out via the space in the hollow shaft 115 surrounding the inner passage 110. In an arc fusion furnace, Fig. 4, the fixed shaft 132 is led into the furnace chamber 127 via an insulating seal 134 and conducts electric current from a source 137 to an outer contact 140 which acts as a rotary non-consumable electrode for arc-fusing material flowing into an ingot mould 128 from a hopper 130. Mercury, circulated by a pump 131 through the rotary contact and a heat exchnager 136, acts as the electro-conductive liquid, hydraulic drive fluid and coolant. Specifications 1,240,547 and 1,418,858 are referred to.

Title: Improvements in or relating to winding-up and unwinding devices of an endless band wound up, except for a loop, in superposed layers forming a spiral
IPC: G03B21/32
Filed: 1933-08-14
Abstract: 414,901. Kinematograph apparatus. HEINIS, H., 15bis, Rue du PrÞ-JÚr¶me, Geneva, Switzerland. Aug. 14, 1933, No. 22716. Convention date, Aug. 18, 1932. [Class 97 (i).] A winding-up and unwinding device for an endless kinematograph film wound up, except for a loop, in superposed layers forming a spiral, in which the winding-up and unwinding of the band is possible both in the direction where the different parts of the band pass from the periphery to the centre of the spiral and in the direction where they pass from the centre to the periphery, is characterised by means which, when the direction of the winding-up and unwinding is such that the different parts of the band pass from the centre of the spiral to the periphery, cause at certain moments a sliding of the exterior layers one upon another and upon the layers nearer the centre of the spiral, the direction of rotation of this sliding being contrary to the direction of rotation given to the spiral owing to the winding-up and unwinding of the latter. As shown in Fig. 8, the spiral 13, with an exterior loop 14, is wound on a core having a number of rollers 15 loose on axes 16, and the film is driven by a sprocket 18 and guided by rollers 19. One face of the spiral is supported by loose radial rollers 20. Mounted loosely on three oscillating levers 21, 22, 23 are rollers 6, 7 and 8 moved in turn against the periphery of the band. As shown in Fig. 11, the other face of the spiral 13 is supported by a movable disc 27 fixed on the rod 28. The shaft 31 driving the sprocket 18, Fig. 8, is driven through a chain and the sprocket 32<1>. The levers 21, 22, 23, Fig. 8, are actuated by cams 32, 33, 34 driven by the pawl 35 and gears 36, 37. On the shaft 31 is a member 39 carrying a pin engaging a star wheel 40 loose on the shaft 28 but integral with the cam 41 engaged by rollers 43 on a lever 42 integral with the shaft 28 which is prevented from turning by a pin 43<1> spring pressed to push the shaft 28 in the direction of the arrow 45. Rotation of the star wheel 40 by the member 39 causes periodic application of the disc 27 against the film spiral. Resilient members may be inserted in the transmission members both of the levers 21, 22, 23 and of the disc 27.
