Title: Improvements relating to electric furnaces
IPC: F27D11/04
Filed: 1955-03-10
Abstract: <PICT:0765154/III/1> <PICT:0765154/III/2> A furnace, especially for the production of carbon disulphide for the reduction of ores, for the production of producer gas from, or of sodium sulphide from carbon and sodium sulphate, by the passage of current through the charge between electrodes in contact therewith, has at least two electrodes 6 of unlike polarity extending in helical form along the inner wall of a lower shaft-like portion of the furnace.  The electrodes 6 are of electrographite or are hollow metal tubes with a layer of graphite or of compressed electrode material, and the ends of the electrodes are bent to pass through the furnace wall for attachment of terminals and for supply of cooling liquid or gas to pass therethrough.  Preferably 3, 6 or 9 electrodes are used with 3 phase current, and the horizontal distance b is appreciably less than e.g. half the vertical distance a between them, so that the current passes mainly horizontally and centrally through the charge.  Each electrode extends preferably one third of a full pitch of the helix; and where 3 electrodes are used, the upper end of one electrode is vertically above the lower end of an adjacent electrode.  The electrodes may however extend over two full pitches of the helix. The electrodes may lie in recesses in the inner furnace wall and be covered with graphite, or may be spaced inwards from the furnace walls.  The electrodes are placed in the lower part, preferably the lower third of the furnace.  The horizontal distance between the electrodes is preferably constant through the zone, or may increase from the bottom upwards, the electrodes being closer where more heat is desired.  The furnace shaft may be of constant cross section or may be conical with its cross section increasing slightly downward. Liquid sulphur may be supplied at least partially through apertures 4 adjacent the top ends of the electrodes, and carbon disulphide vapour is led off through a pipe 3.  Wood charcoal, coke or briquettes are added at a charging device 2, and the furnace has near the base an aperture for drawing off slag.  The electrodes may be slightly adjustable horizontally and may be formed in pairs of like polarity so that if one part is damaged, it may be disconnected.

An insulated conductor is made by extruding about a wire or wires a paste containing a powdered heat-resistant insulant and water, covering the paste with a pervious covering, extruding a metal sheath over the covering with a small clearance, heating a coil of the sheathed conductor in an oven to dry the insulant and then drawing down the sheath to remove the clearance. The pervious covering may comprise a metal tape applied longitudinally or helically so that the adjacent edges of the tape provide between them a passage for the escape of steam. The paste may comprise talc with a small quantity of bentonite as a binder and about 18 per cent water. The cable may be subjected to further drawing down processes to further compress and consolidate the insulation and to obtain elongation of the cable. Specification 674,994 is referred to.

Title: Electronic switching system for switching an alternating current supply
IPC: H03K17/28
Filed: 1969-02-11
Abstract: 1,255,710. Control systems for X-ray apparatus. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 11 Feb., 1969 [13 Feb., 1968], No. 7312/69. Heading H2H. A switching system for use with X-ray apparatus comprises means whereby the firing of a thyristor included in the system is effected at the start of each cycle of an A.C. source from which the system is supplied. X-ray apparatus is supplied from an A.C. supply by way of a diode bridge G10-G13 and a thyristor B10, gating signals for the thyristor being derived from a transistor circuit which ensures that the thyristor is rendered conductive at the start of each half cycle of the A.C. supply. Capacitors C8, C9 are normally charged from a secondary winding T14 of a transformer having its primary winding T10 connected to the A.C. supply, the charging circuit including a rectifying bridge, filter circuit and a change-over contact 53A of a relay S3. A switching operation is initiated by energizing the relay S3 whereupon contact S3A changes to its lower position connecting capacitors C8, C9 to the base of a transistor B7 thus rendering the transistor conductive. Transistors B5, B6 form a bi-stable multivibrator circuit which changes state under the control of transistor B7. Thus, when transistor B7 is rendered conductive by the discharge of capacitors C8, C9, transistor B6 becomes conductive, transistor B5 cuts off and transistor B4 cuts off. The collector of transistor B4 then receives a constant potential, adjustable by a variable resistor R29 which voltage drives transistor B3 near to its operating point. To the base of transistor B3 is applied a further voltage obtained from a secondary winding T13 of transformer T10, this voltage being rectified by a bridge G7 and clipped by a Zener diode G6. Thus, at the collector of transistor B3 a series of pulse signals appear, corresponding to each zero point in the cycles of the A.C. supply. These pulses render transistor B1 conductive thereby producing firing signals for the switching thyristor B10 at the zero points of the cycles of the A.C. supply. Transistor B4 also renders a transistor B2 conductive to energize a relay S1. Closure of switch S1B starts a timing period set by R=f(t) and at the end of this period transistor B7 cuts off to release relay S1 to prevent further operation of thyristor B10. Manual operation may be effected by energization of a relay S2 by closing a push button switch. The diode bridge G10- G13 and thyristor B10 may be replaced by a pair of reverse-parallel connected thyristors in which case the output of transistor B1 is used to energize the primary winding of a transformer, the secondary windings of which supply the gating signals for the thyristors.

At the end of its work stroke cylinder 10 (10a, 1Ob actuates a switch 11 (11a, 11b which feeds a signal through rotary contact 12 on the shaft 8 to switch 16. Switch 16 then passes a pulse to diode D, and the sequence is repeated through another cam and valve for the subsequent operation of another work cylinder. At the end of each stroke of the indexing cylinder 2, lever 5 actuates switch 6 which resets valve 1, the cylinder 2, and the pawl 3 for the next operation. Air pressure is preferably used for actuating the cylinders and valves 9 but they may be electrically actuated.

Title: Improvements in or relating to Apparatus for Automatically Inserting Sliders of Sliding Clasp Fasteners into a Pre-Fabricated Fastener Chain Having Coupling Free Zones
Inventor: EDLER ERNST
IPC: A44B19/62
Filed: 1968-02-19
Abstract: 1,152,154. Machine for inserting sliders. KLEINMETALLWARENWERK HEILIGENSTADT VEB. 19 Feb., 1968, No. 7995/68. Heading E2S. A machine for inserting sliders of sliding clasp fasteners into the coupling-free zones of a continuous fastener chain comprises a support plate 1, a supply reel 4 and storage reel 10, a slider transfer member 19 mounted for intermittent rotation beneath the fastener chain 5, a singling station 17 for supplying said transfer member with sliders 11 from a sorting device 15, and a vertically reciprocable fastener chain holding down member 30 which on downward movement engages the fastener chain at a coupling free zone 8 and depresses it over a slider situated therebelow thereby effecting interengagement. The fastener chain is driven at a slower speed for the actual slider insertion step. A drive 22 generates rectilinear movement by pneumatic hydraulic, electromagnetic or mechanical means, and thereby operates both the singling device 17 and the holding down member 30. In the former case a pin 23 operates through a cam and catch to push the leading slider in the feed shoot 16 onto a holder (18) of the transfer member 19. The drive unit in Fig. 3 (not shown) is pneumatic or hydraulic and comprises pressure chambers (34), (35) each with pistons (36), (37), the latter serving as a stop means for a temporary upward stroke required for the slider insertion, see Figs. 6 and 8 (not shown). This insertion is facilitated by the base of the slider being wider than the top but if this is not the case a resilient template (47) Fig. 10 (not shown) is provided on the holding down member 30. The machine is provided with resilient stop means 46 which holds the assembled' fastener until the coupling elements have been engaged and the slider reaches end stops (6), (7) (Fig. 3) after which the slider is forced through.
