Title: Apparatus for distributing a strand into an open-topped receiver
IPC: B21C47/14
Filed: 1959-06-03
Abstract: 851,032. Coiling ropes. WESTERN ELECTRIC CO. Inc. June 3, 1959 [June 1, 1958], No. 18922/59. Class 109. Apparatus for distributing a strand into an open-topped receiver, comprises means for rotating the receiver, a deflector positioned above the receiver, and means for directing the strand to strike the deflector, whereby the strand upon striking the deflector is deflected in the form of a substantially vertical series of loops into the receiver whilst the latter is rotated. A strand, e.g. a tinsel conductor, is hauled between a belt 42 passing round sheaves 43, 44, 45, 46, the sheave 44 being adjustably spring-urged to tension the belt 42, and a driven drum 41 and is deflected by a plate 12 which causes the strand to fall in a vertical series of loops into a receiver 13 rotating on a turntable 27 level with the floor. The plate 12 is moved automatically from the position 12<1> when an outer series of loops has been laid in the receiver to the position for laying an inner series of loops in the receiver, the shift being initiated by a magnetic switch actuator 31 and switch 32 through a control circuit when the receiver 13 has rotated through a predetermined angle, preferably 345 degrees. The angular speed of the receiver 13 is automatically adjusted so that the speed of laying is the same in both positions of the deflector 12. The angle at which the strand leaves the belt 42 is varied by adjusting the vertical position of the sheave 46. Instead of a plate 12 the deflector may comprise an endless belt having its downwardly moving side facing the strand, or it may be spiral in cross-section.

Title: Solid electrolyte capacitors
IPC: H01G9/00
Filed: 1978-05-15
Abstract: A fuse for a solid electrolyte capacitor is made of two exothermically alloyable metals such as aluminum and palladium. The fuse has a series electrical connection with and a thermal connection to the capacitor body. A defective and overheated capacitor section results in abnormally high currents so that the fuse temperature is elevated by ohmic self-heating and/or by the flow of heat from the overheated body. When the alloying temperature of the fuse is reached, the temperature of the alloying fuse momentarily becomes very high and opens essentially along its entire length.

IPC: B22C11/00
Filed: 1959-06-12
Abstract: 899,753. Machine-tool details; indexing. FOSTER, YATES & THOM Ltd. June 3, 1960 [June 12, 1959], No. 20219/59. Class-83 (3). [Also in Group XXIX] An indexing mechanism for machine parts comprises a fluid-operated cylinder and piston arrangement, crank means operable thereby over 180 degrees through a dead-centre position for driving the part to be indexed, a directional valve arrangement for reversing the action of the cylinder and piston arrangement while the crank passes its dead-centre position and means for controlling the supply of pressure fluid to stop the crank at an indexing position. The part to be indexed is connected through a pinion 9, Fig. 1, on the indexing device and may be a rotary or reciprocating table. The pinion 9 is secured to a crank-shaft 7 which is rotated by a connecting rod 5 forming part of a double-acting piston 4 in an oscillating cylinder 6. The cylinder 6 is pivoted about trunnions 3 in bearings 4 in the indexing device. Spring-pressed relief valves 22 to relieve the pressure from either side of the piston to the other are embodied in the piston. One of the trunnions 3 is utilized as a directional valve and has passages 12, 13 communicating with the cylinder ends and with a peripheral groove 15, Fig. 4, in the trunnion. Communication between the passages 12, 13 is stopped off by two diametrically arranged plugs 20, 21 which slide around the groove 15. Supply and exhaust passages from a reversible control valve lead into the passage 15 from ports 16, 17 in the trunnion bearing. Operation. The indexed positions of the crank-shaft are at 180 degrees and at rightangles to the dead-centre position and the control valve is operated by solenoids controlled by switches on the indexed member. The piston is approximately at the mid-position when an indexed position is reached and moves away when the control valve is opened to rotate the crank. The directional valve reverses the flow of pressure liquid or air after the deadcentre position is reached and at this point the plugs 20, 21 do not completely cover the passages 16, 17 so that pressure and exhaust are connected as are the cylinder ends. A choke valve 24, Fig. 1, operated by a cam 24a may be employed to slow down the parts as an indexed position is approached. In a second embodiment, the piston-rod operating in the oscillating cylinder is provided with a central shoulder and two slidable sleeves, one each side of the shoulder, act as pistons (see Figs. 6 and 7, not shown). Specification 831,193 is referred to.

Abstract: 611,051. Pipe couplings. MILLER, A. W. Aug. 7, 1945, No. 20232. [Class 99 (i)] A pipe coupling employs a screw-threaded sleeve 15, a collar 18 composed of two or more separate segments each tapered on its external surface, and a screw-threaded clamping body 20 to engage the sleeve and embrace the collar such that screwing the clamping body on the sleeve moves the embracing portion longitudinally, thereby imposing radial pressure only on the collar segments, forcing them to contract and grip the pipe end 11 which is placed within the gripping surface of the collar. Fig. 1 shows the sleeve 15 as part of a coupling. member 10 which also has a coned end nipple 16 which fits into a correspondingly flared end 17 of the pipe 11. The segmented collar 18 is tapered on its outer surface to conform with the inner surface of the conical clamping body 20. A spring may be fitted inside the collar to force it open when the clamping body is unscrewed. The other end of the member 10 may be similarly formed or, as shown in Fig. 1, may be threaded at 12 to engage a standard fitting. Fig. 3 shows an arrangement for coupling two pipes, the adjacent ends of which are close together; 16<1> is a doubly coned nipple, 18<1> the segmented collar, and 20<1>, 20<11> the clamping nuts. When a rubber hose, or similar pipe, is to be coupled (Fig. 4), the nipple is not coned but formed as a hollow cylinder 34 with serrations on its external surface, the inner surface of the split collar 37 having corresponding serrations 36 so that the hose, when inserted, shall be firmly gripped on screwing the clamping nut 42. Fig. 6 shows the application to a pipe without a flared end, but having grooves 49 which are engaged by complementary annular teeth 62 on the segmented collar 60. There is no nipple in this case, the end of the pipe 11<1> abutting against the shoulder 54 inside the coupling member 50. The end 70 of the collar is forced into contact with the shoulder 69 and the teeth into the grooves in the pipe on tightening the nut 55. Pipes carrying low-pressure fluid may have plain ends as shown in Fig. 8, but the inner surface of the collar 181 is parallel to the pipe surface and a compressible gasket W provided to seal the joint; a spring band Z surrounds the gasket to improve sealing. A reinforcing nipple with an external annular flange may be fitted.

Abstract: 683,326. Moulder's cores. AKTIEBOLAGET AKERS STYCKEBRUK. Aug. 16, 1950, No. 20357/50. Class 83 (i). A core, adapted to collapse when the surrounding cast metal 15, Fig. 7, contracts, comprising a set of segments 1 spaced by inwardly flaring wedges 2, is characterized in that the parts pivot on an end ring 3, Fig. 3. The wedges and segments 1 are prevented from moving radially out, beyond the position shown, by end rings 3, 6, Fig. 3. The ring 3 also prevents the adjacent ends of the parts 1, 2 from moving in but allows them to hinge at said ring and turn inwardly when the casting contracts. This action is prevented, until contraction occurs, by spring- pressed pins 11 on the wedges engaging recesses in the ring 6 or, in modifications, by springs attached to the wedges urging them radially out. Other forms of ring 3 are also shown. The cores shown are for forming the socket end of centrifugally-cast pipes, and when casting iron may be preheated and coated with blacking.
