Title: Improvements in or relating to means for indicating the failure of an electric supply
IPC: H01H73/14
Filed: 1946-02-11
Abstract: 607,738. Indicating faults. GENERAL ELECTRIC CO., Ltd., and PYE, J. F. Feb. 11, 1946, No. 4183. [Class 37] [Also in Group XXXVII] A buzzer for indicating failure of an electric supply is energized from an auxiliary electric supply on failure of the main supply. Manually operable means are provided for rendering the buzzer inoperative and means operated in dependence upon return of the main supply render it operative again. A de-wirement indicator for indicating that the trolley of a trolley-bus has left the overhead line comprises two neon lamps 6, 7 in series across terminals 1, 2 connected to the trolleys through fuses 4, 5. A buzzer 8 is fed from a battery 9 through contacts 10 which are held open when the trolleys of the bus are energized. A relay 11, having its operating coil 12 in series with a resistance 13 across the terminals 1, 2 has a spring-biassed armature 14 to which is attached a rod 15 pivoted to the free end of a pivoted arm 16 which controls the contacts 10. On energization of the coil 12 the relay moves the arm 16 which opens the contacts through a pillar 17 so that when the trolleys are energized the contacts 10 are open and the buzzer 8 deenergized. On failure of the supply, the armature 14 is retracted by its spring and the contacts 10 close the buzzer circuit. In order to stop the buzzer 8 if the trolleys are pulled down for parking, a push-button 18 is provided, slidable in a cylinder 19 which houses the arm 16. A pin 23 on the push-button 18 engages an inclined surface 24 on the arm 16 as the button is pushed in and moves the arm 16 to open the contacts 10. The pin 23 latches in a notch 25 so that the contacts remain open. On energization of the relay 11 by replacement of the trolleys, the arm 16 is moved downwards sufficiently to release the push-button and maintain the contacts 10 open.

Title: Apparatus for use in bringing about movement of a nuclear reactor control member relative to the core of the nuclear reactor
IPC: G21C7/14
Filed: 1973-01-26
Abstract: 1387105 Controlling reactors INTERATOM INTERNATIONALE ATOMREAKTORBAU GmbH 26 Jan 1973 [29 Jan 1972] 4224/73 Heading G6C In nuclear reactor control apparatus, an absorber rod 12 is releasably held by a coupling device 9, 10 mounted on a drive-rod 5, 6 for movement therealong, the coupling device being positioned within a control sleeve 19 which is rotatable to release the absorber rod 12 from the coupling device, rotation of the control sleeve 19 being caused by axial movement of an armature 14 of an electromagnet 2. In the embodiment shown, the armature 14 includes projections 17 which slidably engage in inclined slots 18 in the control sleeve 19 in order to translate axial movement of the armature into rotary movement of the sleeve. The outer sleeve 10 of the coupling device is axially movable, but rotationally fixed, relative to the control sleeve 19 so that rotation of the latter brings about rotation of the sleeve 10 relative to the inner sleeve 9. Such relative rotation between the sleeves 9, 10 causes recesses in the sleeve 10 to become aligned with balls 11, mounted in the sleeve 9, so that the natural weight of the rod 12 urges the balls into the recesses thereby permitting the rod to fall to shut down the reactor. A spring may be provided to assist downward propulsion of the rod (Fig. 5, not shown). The armature 14 normally is held in a raised position by the electromagnet 2 but is urged by a spring 15 to its downward position so as to initiate rapid shutdown when the electromagnet is deenergized. The inner sleeve 9 of the coupling device is secured to a lead nut 8 and prevented from rotation by engagement with parts of a guide tube 21 which extend through apertures in the control sleeve (Fig. 3, not shown). The nut 8 is engaged upon a threaded part 6 of the drive-rod; the threaded part 6 is connected, by a plug connection 7, to the upper part 5 which is drivable from electric motor 3 via gearing 4. When the reactor cover 1 is removed, the motor 3, gearing 4, magnet 2, armature 14, spring 15 and its enclosing sleeve 16, and drive rod part 5, are removed with it, leaving the drive rod part 6 still in the reactor. In another embodiment (Fig. 4, not shown) the armature and control sleeve are connected by rack-and-pinion gearing.

[Class 38 (v)] In order to prevent access of contact-dust, produced by arcing at the horizontallyseparating contacts 4, 5, to the operating- magnet coil 13 and the space 15 between the core 14 and armature 12, the base 1 is provided with a forwardly-extending part 2 having a downturned extension 3. The armature and contact 5 are carried on a member 7 pivoted at 8. In Fig. 2, the base is in the form of an enclosing casing, the vertical front wall 16 of which is apertured. at 17 for admitting the contact - operating means 18. Modifications comprise the replacement of the front wall 16 by a removable member, Fig. 3 (not shown), which may have a tubular extension entering the casing and serving as former for the coil 13, Fig. 4 (not shown).

Abstract: 602,738. Resistance measurements. ENGLISH ELECTRIC CO., Ltd., DOUGHTY, E. H., and WARDLE, L. G. Feb. 22, 1945. No. No. 4510. [Class 37] In an arrangement for measuring a small current passing through a high resistance, e.g. the leakage current through an insulator R1, a selected known resistance R2 is connected in series with R1 across a high voltage source T1, T2. On depression of a push-button B, the voltage drop across resistance R2 is connected in series opposition with a measured source of voltage P2 across the grid resistance R4 of a " magic eye " tube V2 which is normally in a " partially-open '' condition. P2 is adjusted until the depression of button B causes no change in the condition of the tube V2 when the voltage across R2 is the same as that taken from potentiometer P2. Hence, the current through resistance R1 is known and its resistance may be calculated. A neon tube V1 is arranged to shunt R2 in case of the breakdown of the high resistance R1. Condensers C1, C2 are smoothing condensers used when the direct current sources are derived from rectifiers.

Title: Improvements in or relating to the production of low carbon alloys
IPC: C22C33/04
Filed: 1940-03-11
Abstract: 539,461. Low carbon alloys. RENNERFELT, I., and KALLING, B. M. S. March 11, 1940, No. 4540. Convention date, March 11, 1939. [Classes 72 and 82 (i)] Low-carbon alloys of iron and/or another metal similar to iron such as cobalt or nickel, containing up to 30 per cent. of an alloying metal having a greater affinity for oxygen than iron such as chromium or manganese are produced by reducing an ore having a high percentage of alloying metal with carbon and iron ore or iron or similar metal to produce a ferro or like alloy having a high carbon content and an amount of the alloying metal up to 30 per cent. and heating in finely divided state to 1000‹-1200‹C. in a suitable atmosphere, to remove the greater part of the carbon. The alloy may be granulated by crushing, or by cooling in water, to an average size of 1.0-1.5 mm. The decarbonizing may be effected in a tubular rotating furnace not above 1200‹C. to avoid sintering, or in a stationary retort at a higher temperature, or on a conveyer passing through a tunnel furnace, or in an electric furnace. The atmosphere may contain carbon dioxide and monoxide in the proportion of 25 per cent. and 75 per cent., whereby decarbonization of an alloy containing 20 per cent. Cr can be effected without substantial oxidation of the chromium. The de-carbonization may be effected at reduced pressure, or the gas may be diluted with hydrogen or nitrogen to reduce the carbon monoxide concentration. Hydrogen or steam may be added. This gas mixture may be burnt in the cooler zone to pre-heat the charge. An alloy containing 5 per cent. carbon may be de-carbonized down to 0.25 per cent. carbon in an oxidizing atmosphere, and then down to 0.05 per cent. carbon in a hydrogen atmosphere which reduces the metal oxide previously formed. De-carbonization may also be effected by solid and liquid oxidizing substances with the simultaneous supply of some gas such as hydrogen. The chromium alloy which is to be de-carbonized may be produced by direct reduction of chrome and iron ore with carbon in an electric furnace or a blast furnace. The de-carbonization of the granular alloy may be effected first in a gas atmosphere with stirring, and then in retorts at a higher temperature. A metal oxide may be added, and/or a de-carbonizing gas passed through the charge. The partly decarbonized alloy may be compressed into solid bodies, which are heated in a furnace, with solid or gaseous oxidizing matter to oxidize the remaining carbon.

A pulse generator particularly for railway track circuits comprises a transistor T in series with the primary of a transformer C feeding the load R across a voltage source B. Over-voltage and over-current protection is provided to protect the circuit from spurious voltages emanating from the track. As described, transistor T is periodically made conductive by pulses from a control unit 3 comprising a class C oscillator 11 coupled via a number of saturated stages to the base of transistor T. The oscillator 11 provides a trapezoidal waveform which is squared by transistor 18 and amplified by transistors 33, 36 and 39 before being used to control the current in transistor T. When the current in transistor T is cut off, a pulse of several hundred volts is induced in the secondary winding, decaying exponentially to zero. The amplitude of the output pulse may be adjusted by variable resistor r. The protective circuit comprises fuse 7, diodes 6, 9 and voltage-dependent resistor 8. Bias for transistor 33 is obtained by rectifying at 29 the output of a further oscillator 23.

[Class 87 (ii).] Boxes or other articles are made of pulp by perforated moulds of approximately the internal shape of the articles, the moulds being immersed in the pulp while a high partial vacuum is produced within the moulds, the articles formed on the moulds being removed after drying and stamped to final form. The perforated moulds 20, Fig. 1, may be clamped by bars 5 and locking members 7 over the open faces of a polygonal or circular drum 2, having longitudinal partitions 10 connected to a hollow shaft 9 which rotates intermittently or continuously about a fixed shaft 16. The shaft 16 has an internal cross partition midway along the drum so that the two ends of the shaft are isolated, one end communicating with means for producing a vacuum the other end being open to discharge. Funnels 12 on the shaft 9 communicate during certain periods with ports 17 in the vacuum end of the shaft 16 in order that pulp may be deposited on the moulds and air drawn through the deposited pulp to dry it partially. Thereafter, communication with the ports 17 is cut off and the water collected in the chambers 2 passes to discharge through the other end of the shaft 16. The moulds on their carriers are then placed in a frame 25, Fig. 3, the moulds at one end of the frame bearing against resilient buffers 34, while the moulds at the other end are struck by spring released, cam actuated hammers 27 thus loosening the articles on the moulds whereupon the moulded articles fall on to a delivery plate whose distance below the moulds may be adjusted.
