Abstract: 416,493. Knitting-machines. WILDMAN MFG. CO., Norristown, Pennsylvania, U.S.A.-(Assignees of Howie, K. ; Norristown, Pennsylvania, U.S.A.) March 13, 1933, No. 7632. Convention date, April 29, 1932. Addition to 411,517. [Class 74 (ii).] The machine described in the parent Specification is provided with auxiliary pattern mechanism controlling one or more of the yarnguide carrier selecting slides C for producing horizontal striped effects. The auxiliary pattern mechanism comprises pattern chains C<11>, one to each slide C to be controlled, and having high and low parts engaging levers 8, each of which is connected to a bellcrank lever 18 operable upon a slide C. The ratchet wheel 11 carrying the pattern chains is actuated by a pawl 12 and projections 70<x> on a cam drum P, and a mask 30 controlled by a cam 23 on the cam shaft b is provided for holding the pawl 12 inoperative. The wires 17 connecting the levers 8 to the bell-crank levers 18 are passed over pulleys 20 carried by a pivoted frame 21, and the frame 21 is rotated by the cam 23 simultaneously with the actuation of the mask 30 so that the wires 17 are slackened. The high and low parts of the chains C<11> are so arranged that at least one of the levers 18 is engaged by a high part so that at least one slide C is actuated while the auxiliary pattern mechanism is operative ; slackening of the wires 17 permits a lever 8 to be lifted without actuation of the corresponding slide C when the mask 30 is interposed between the pawl 12 and the ratchet wheel 11. The cam shaft b, with its slide actuating cams, is rotated once for each stocking in the manner described in the parent Specification by ratchet and pawl mechanism under control of the main pattern mechanism.

Title: Improvements in vacuum electric tube devices
IPC: H01J19/42
Filed: 1927-03-19
Abstract: 292,664. Robinson, E. Y., and Metropolitan-Vickers Electrical Co., Ltd. March 19, 1927. Vacuum tubes. - The electrodes of vacuum tubes such as thermionic valves and rectifiers are supported by wires or strips, &c. secured to the electrodes at one end and held in the pinch or seal and lateral movement of at least one electrode at its other end is restrained bv a framework or standard mainly or wholly of metal and independent of all the electrodes and their supports and leads, the framework permitting longitudinal movement of the electrodes due to expansion and being supported from the re-entrant tube carrying the pinch by mechanical means not involving fusion of glass. The electrodes can be assembled in jigs and the framework added subsequently, heavy leading-in wires and undue strain on these wires being avoided by the framework. The framework may restrain the electrodes at their ends, or at their centres of percussion, against all lateral movements or mainly against lateral movements at right-angles to the pinch. In a three-electrode tube, Fig. 1, the oval anode 1 and grid 2 are supported by wires 4, 7 in the pinch 5 and the W-shaped cathode 3 is supported by wires 10, 11 in the pinch 5 and by a wire 8 in a glass head 9 tying the electrodes together at the ends remote from the pinch, wires 12 being bent at 14 and welded in two places to the wires 4 to make the structure rigid in the plane parallel to the pinch. A framework of wires 15 secured to the re-entrant tube of the pinch 5 by bands 16 carries a disc 17 with an aperture loosely engaging the wire 8 to restrain the electrodes against lateral movements beyond the elastic .limits of the wires in the pinch 5. In a modification, a cross-wire between the wires 4 slides in a vertical loop in a cross-wire on the framework. In a full wave rectifier, two flat anodes side-by-side in the plane of the pinch are supported by wires extending between the pinch and a glass bead and each surrounds a hairpin cathode. The loops of the cathodes are supported by springs on a wire in the bead and movements of the electrodes at right angles to the pinch are prevented by the engagement of this wire with a loop or aperture in a cross-piece of the restraining framework. In a modified fullwave rectifier, Fig. 7, two anodes 38 of U- shaped cross-section are oppositely arranged at right angles to the plane of the pinch and each anode encloses an indirectly heated cathode 44 comprising an oxide-coated tube around an insulated hairpin heater..Supporting rods 39, 46 extend between glass beads 41, 45, which tie the electrodes together at both ends, the rods 39 extending into the pinch and the rods 46 lying within the open sides of the anodes and being connected to one end of the cathode heater and to the cathode tube to act as discharge shields. A framework 53 has a looped cross-piece 56 engaging the lead 48 to the cathodes to restrain movements of the electrodes at right angles to the pinch.

Abstract: 720,829. Furnace hearths. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. March 20, 1953, No. 7727/53. Class 51 (2). In a furnace hearth constructed from an assembly of interlocking rectangular plates, each plate has two meeting edges provided respectively with a junction member 7 formed with a vertical groove 2, Fig. 5, and a junction member 8 formed with a vertical groove 6, Fig. 6, and with a further groove 4 of partly circular cross-section extending partly under the upper surface of the plate. The member 7 has a lip 5 on the under surface of the plate, extending a short distance inwardly at right angles to the edge. Along the edge opposite to that having the junction member 8, there is provided a projecting lip 3 parallel with the groove'4, and having a partly circular crosssection. The fourth edge of the plate is formed with a downwardly projecting lip 1, Fig. 5, parallel with the groove 2. The hearth is assembled by first laying a row of plates from left to right with the lip 1 of one plate engaging the groove 2 of the previous plate, then starting on the left again by placing the lip 3 of a plate in the grooves 4 of two adjacent first plates Fig. 3, and lowering it into position with its lip 5 engaging the groove 6 of a plate in the previously laid row. The next is similarly laid and its lip 1 enters the groove 2 of the previous plate. In this way the plates are interlocked to form a hearth free from cracks and thus preventing the direct passage of oxide flakes, &c., onto electric or other heating elements disposed below the hearth.

Abstract: 1,237,595. Terminals. NORTHERN ELECTRIC CO. Ltd. 13 Feb., 1969 [16 Feb., 1968], No. 7780/69. Heading H2E. A connector 10 comprises a pair of legs 12, 14 extending from an integral base section 16, the legs adjacent the base section being separated by a slot 22, and the legs adjacent the free end having edges 48, 50 which penetrate and slice the insulation of a conductor 42 inserted therebetween via an entry slot 24 and centering region 26. The width of the conductor-gripping portion 28 is less than the normal diameter of the conductive part of the insulated conductor, so as to achieve both good electrical and good mechanical connection. The legs 12, 14 are initially spread apart by a tapered punch or wedge (52, Fig. 2, not shown) in the slot 22, the elastic limit being exceeded by a predetermined amount .to produce a residuel deformation, which further ensures that the legs will tightly grip a conductor. For optimum cutting effect, the included angle-formed by the faces 34, 36 is between 90 and 120 degrees inclusive. The connector is made from a flat sheet of conductive material, e.g. steel, and may be one of several joined together at their base portions. To prevent wear and corrosion, a layer of, for example, tin on copper, may be applied. A connector having three legs, with two conductor receiving portions, is disclosed (Fig. 4 not shown) as is a slotted hand tool to facilitate insertion of the conductor (Fig. 3, not shown). Reference has been directed by the Comptroller to Specification 1,030,235.

Title: Improvements in and relating to protective systems for metal vapour rectifiers
IPC: H02H7/12
Filed: 1926-03-23
Abstract: 250,216. Akt.-Ges. Brown, Boveri, et Cie. April 6, 1925, [Convention date]. Cut-out arrangements. - A vapour rectifier is protected against internal faults, particularly back-ignition, by a relay R1 with two oppositelywound windings U, V carrying currents shunted from the input and output currents respectively and having their turns so proportioned that, normally, the windings balance one another. In the event of an internal fault the balance is disturbed and the relay closed to connect the tripping coil L of the circuit-breaker S to an auxiliary supply. A subsidiary overload trip M energized from a series transformer W and provided with a time-lag action may be added. The system shown is designed to overcome faulty operation arising from the existence of harmonics of different frequency in the input and output sides. The windings U, V are inductively related so that by their connection to the current shunts S1, S2 each winding acts as a substantially short-circuited secondary to the other and carries a compensating current induced in it by the harmonic in the other.
