Title: Static electrical converter arrangements with series-connected converters
IPC: H02J5/00
Filed: 1975-04-04
Abstract: 1493977 Controlling converters ASEA AB 4 April 1975 [5 April 1974] 13840/75 Heading H2F In a series arrangement of two converters 1, 2 each having a by-passing switch 7, 8 and each having a control system 9, 10 controlled from a regulator 11, a starting regulator 21 is provided for the reconnection of a by-passed converter and controlled in dependence on the effective difference between the current in the by-passed converter and the sytem current. The invention may be applicable to a series arrangement of converter bridges 1, 2 in a single station or to a HVDC system having series-connected stations. Electronic switch 22 is normally set to the right hand position so that regulator 11 controls the current in the D.C. side in dependence on the summation at 12 of the current order 13, current margin 14 and actual current derived from the circuit 18 in dependence on the largest signal from current transformer 19, 20 and transductor 16. After a converter 1, 2 has been by-passed by closing the appropriate switch or breaker 7, 8, a de-blocking signal may be applied to set electronic switch 22 to its left hand setting and to open switch 8 after a delay. Before the switch 8 is opened, the control angle of the by-passed converter 2 is set to approximately 90 degrees by comparing the station current at 16 with the current at 20 on the A.C. side of the by-passed converter 2. This minimises the current in the by-pass switch 8 and creates appreciable ripple in the by-pass circuit so that an AC breaker can be used. Control system 10 is initially controlled by a pulse from a monostable 25 triggered by the de-blocking signal. When the bypass switch 8 has been opened, the voltage across it is monitored at 24 and fed to the summation circuit 23 which is arranged to reclose the switch 8 if arcing does not cease within a predetermined time. Modifications.-The starting regulator may alternatively be controlled in dependence on the current in the switch 8, as measured by transductor 27 and the voltage as measured at 24.

Title: Resolution of alkali metal amalgams, and the extraction of refractory metals
Inventor: AVERY JULIAN MILES
IPC: C22C3/00
Filed: 1958-05-01
Abstract: 837,067. Concentrating amalgams; extracting refractory metals. ETHYL CORPORATION. May 1, 1958, No. 13911/58. Class 82(1) An alkali metal enriched amalgam, which may be used as a reducing agent for refractory metal halides, is continuously obtained from a dilute amalgam by feeding the dilute amalgam to a boiling alkali metal enriched amalgam which is partly heated by compressing the evolved mercury vapour and condensing it in a heat exchange coil immersed in the amalgam. Additional heat is supplied when required by an electric immersion heater, and the dilute amalgam is preheated by the hot, alkali metal enriched amalgam removed from the vaporization chamber. In a modified method mercury is vaporized from a thin film of amalgam which is arranged to flow over a weir and pass down the inside of a vertical tube the outside of which is heated by hot compressed mercury vapour. To produce a refractory metal, an amalgam, preferably containing from 3 to 10% by weight of sodium is reacted with a refractory metal halide at a temperature between the boiling point of the amalgam and 1500‹C. A particular embodiment, as shown, describes the production titanium by feeding the amalgam, at its boiling point through the inlet 52 into the reactor 50 heated to about 500‹C. where it reacts with titanium tetrachloride supplied through inlet 51. A mixture of mercury vapour, sodium chloride particles and titanium particles is withdrawn by the suction hood 54 to the cyclone 53 from which mercury vapour passes via the outlet 56 and from which sodium chloride and titanium particles pass via the pipe 55. The titanium and sodium chloride may be separated by vacuum distillation.

Title: Production of isomeric dichlorobutenes
IPC: C07C17/358
Filed: 1961-04-18
Abstract: Aluminium fluoride having crystallite size of at most 500 Angstrom units radius is prepared by the reaction of AlCl3 and HF.  U.S.A. Specification 2,673,139 is referred to.ALSO:Either of the isomers 1,4-dichlorobutene-2 and 3,4-dichlorobutene-1 is converted to the other by heating to at least 120 DEG C., in the presence of a substantially anhydrous aluminium fluoride catalyst, of crystallite size at most 500 Angstrom units radius, and separating the resulting mixture of dichlorobutenes, e.g. by fractional distillation.  The conversion may be effected in the liquid phase, preferably under reflux; when the lower-boiling isomer 3,4-dichlorobutene-1 is the desired product, it may be removed from the column as it is formed. Inert diluents may be present, e.g. CCl3CF2CCl2CClF2, CCl3CClFCCl3 and CCl2-FCClFCClFCCl2F.  The conversion may also be effected in the vapour phase, e.g. by passing an inert gas such as nitrogen through the boiling isomer, passing the vapour mixture through a heated tube (e.g. at 150-400 DEG C.), condensing the product and separating the isomers.

Title: Apparatus for successively depositing articles
IPC: B65B5/10
Filed: 1965-04-02
Abstract: 1,098,506. Unloading endless conveyers. AVIOLANDA MAATSCHAPPIJ VOOR VLIEGTUIGBOUW N.V. April 2, 1965 [April 3, 1964], No.14146/65. Heading B8A. An installation for loading and unloading a number of bottom unloading holders 1 mounted on an endless chain conveyer 2 comprises a holder loading station 6 and a station 7 at which articles are unloaded into compartments 9 of a box 8 carried on an intermittently driven transverse conveyer 10. The holders 1 are each formed of two relatively pivotable parts 18, 19 and 23, 24 which are held in an unloaded position IF, a loaded closed position le or a loaded open position 1b in which the article is unloaded. The upper end 19 of the downstream pivoted part of each holder 1 has a shaft which rides in a slot in the upper end 24 of the upstream pivoted part, and mounts a nylon or steel roller 21. At the start of the loading/unloading run of the conveyer the rollers 21 engage a guide 65 which pivots the holder parts into the unloaded position 1F. If a holder is loaded at 6, the weight of the article in the holder pivots the parts into the loaded closed position where the roller 21 engages a guide 26. At the unloading station 7 the holders not carrying an article have their rollers 21 pass straight through a track 29, the pivoted parts being maintained in the IF position by a counterweight on the downstream part 18, 19, a tacky grease in the pivot bearings, or by spring or magnetic means. The rollers 21 of the loaded holders however move along a guide 32 comprising pivotable regulation elements 34, one for each row A, B, C, D, E of box compartments 9. As a roller 21 engages a downstream fixed regulation element 34A it is deflected down into a track 31 where the holder parts move into the open position to deposit the article in compartments 9A. In passing down into track 31, the roller 21 deflects downwardly a control element 38 which is coupled to or integral with the next upstream regulation element 34 which is therefore caused to rise to deflect the following roller into the unloading positions for compartment 9B of box 8. Each regulation and control element pair is returned to its inoperative position as the rollers 21 move along the track 31. An extension on the most upstream of the regulation elements, i.e. associated with box compartment 9E, causes energization of the motor circuit for the transverse conveyer 10 when said elements are returned to their respective inoperative positions.

Abstract: 647,370. Securing stop-rings on shafts. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 26, 1948, No. 14257. [Class 80(ii)] [Also in Group XL(c)] In a preselector device for setting a shaft, e.g. the tuning shaft, wave-change switch, or other circuit selector of a radio receiver, a drum geared to the settable shaft carries a plurality of stop rings each co-operating through an actuating member to control a switch in the circuit of the driving motor to stop the shaft in a preselected position; the rings are rotatably mounted on the drum and normally locked thereto, means being provided for unlocking each ring independently for adjustment of the setting postion thereof. The tuning shaft, not shown, is geared at 6 with a 1 to 1 ratio to a shaft 5, Fig. 2, carrying rigid therewith a drum 4 on which are rotatably mounted individual stop rings 8 separated by circlips 7. The drum 4 carries a number of spring biassed rods 14, one for each stop ring, axially slidable therein. In the outer position of each rod 14 a cam portion 16 on the rod forces a ball 20 through a radial hole in the drum to lock the associated ring to the drum. Depression of any rod against the action of its biassing spring 18 releases the associated stop ring for adjustment purposes by permitting the corresponding ball 20 to move radially inwards. The actuating heads 17 of the rods 14 co-operate with a disc 21 capable of limited angular play on the drum shaft and biassed by a spring 22, so that depression of any rod first releases any previously depressed rod by slightly rotating the disc, and then, as its head 17 passes through the disc, locks itself in the depressed position as the disc returns to its off-centre position under the action of spring 22. Any depressed rod may also be released by slight manual rotation of the disc. Riding on the periphery of each stop ring 8, Fig. 3, is an insulated rocking riser 11 held in a slot in a cantilever spring strip 27 carrying two switch contacts 29 co-operating with contacts 30 carried on the bifurcated ends of an associated spring strip 31, the strip pairs 27, 31 for each ring being suitably insulated. In a tuning operation a preselector switch (not shown), is set to the desired position whereby the driving motor is energized in series with the corresponding switch 29, 30 and drives the tuning shaft and the drum until the riser 11 of the operative switch falls into the notch 9 of the associated stopring to open the switch and break the motor circuit. The inoperative risers are shaped as shown so that they fall into and are rocked out of their associated stop ring notches as the drum rotates.

Title: Improvements in or relating to electric meters and to selective remote control systems employing such meters
IPC: H04Q9/00
Filed: 1928-05-16
Abstract: 317,422. Reyrolle & Co., Ltd., A., and Leeson, B. H. May 16, 1928. Indicating; particula,r readings; maximum movements.- An electric measuring-instrument particularly for obtaining an indication at a control station of the condition of a selected remote circuit, has a pointer which is clamped in its deflected position when the meter is de-energized, means being provided for indicating whether the meter is energized or not. The pointer B, Fig. 1. is mounted on a shaft C and is moved from its zero position against the action of a spring or gravity under the influence of a coil D which is energized through a contact E<1> of a selector drum E and pilot wires F, F<1> from the remote source. Mounted on the shaft C and fixed to the pointer B is a disc G, against the edge of which a brake block H is normally pressed by a spring (not shown). The brake block H is attached to an arm J pivoted at J<1> and carrying an armature L<1> which is attracted by an electromagnet L when this is energized from a local battery M through a contact E<2> of the selector E. The contacts E<1>, E<2> are so arranged that the circuit of the electromagnet L is completed at the contact E<2> when, or shortly before, the circuit of the operating coil D is completed at the contact E', thereby lifting the brakeblock H and releasing the. pointer B. A lamp N, or other device, is arranged to have its circuit completed at a contact J<2> when the lever J is in its raised position, so as to indicate when the instrument is operating. In a modification the pointer B carries a pin which drives a second pointer, which is freely mounted, on the shaft C and fixed to the disc. G. On de-energization of the meter, this second pointer is clamped by the brake-block H, the pointer B being free to return to zero. Alternatively, the second pointer may carry a ratchet-wheel and pawl so as to indicate the maximum reading of the pointer B during the period of energization. The pawl is momentarily released by the electromagnet L on energization of the meter. A modification is described in which the brake-block H is applied to the face of the disc G, or two blocks H may be applied to opposite edges of the disc.
