Title: Improvements in or relating to evacuating arrangements for mercury arc rectifiers
IPC: H01J13/28
Filed: 1933-03-13
Abstract: 418,205. Evacuating vapour arc converters. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and GALLIZIA, E., c/o General Electric Co., Witton, Birmingham. March 13, 1933, No. 7568. [Class 8 (i).] High vacuum pumps (not shown) are individually connected with vapour arc converters 1 and discharge into a common chamber such as an interstage reservoir or bus pipe 7 evacuated alternately by backing pumps 11. The connections between the converters and the rough pumping means are made through insulating pipe sections 8 which comprise bored blocks 18, Fig. 2, of ebonite &c. to the ends of which the pipes are secured by packed flanges on the pipes. The bus pipe 7 is partitioned by valves 14. The backing pumps are driven by motors 28 fed from three-phase bus-bars 31, 32, 33 through contactors 34, through the windings 37, 38 of overload relays latched either in closed or open position ; in the open position they contact at points 49, 50. The contacts 34 are closed by windings 55 connected through a common lead 58 connected through one of three contacts 59 to a line 62 connected to the bus-bar 33. The contacts 59 are associated with the main oil switches (not shown) connecting the rectifiers to the bus-bar 33. The winding 55 is energized on completion of a circuit from bus 32 over line 62, one of the contacts 59, line 58, line 63, overload contacts 43, 44, contacts 64 of a time switch also making contacts 65, 66, and fuse 67, to the bus 31. The time switch makes contacts 64, 65, 66 in succession; these contacts may overlap. On occurrence of overload, the contacts 49, 50 are made, and the switch 65 short-circuited over lines 70, 71. Across the time switch contacts 64 are connected contacts of no-volt contactors having contacts 76 and hold-up windings 79 connected in parallel between bus 31 and line 62 and having current-limiting resistances 82 in series with them. The motors and pumps each operate in turn; if any motor is overloaded the overload relays bring the next pump into use, and this is also effected if a no-volt relay falls closed owing to failure of the associated contactor and blowing of the fuse 67. Alternatively the bringing of a new pump into operation may be effected by rise in the pressure due to faulty working, a warning signal being given. Means may be provided whereby a particular pump and motor are started together. Hand-operated control switches enable any rectifier to be reformed on site, the section of bus pipe being cut off and evacuated by its own pump.

Abstract: 441,519. Vacuum tins and cans. RUSSELL, A. S., 6, Cambridge Park, Redland, Bristol. March 12, 1935, No. 7642. Addition to 428,684. [Class 125 (iii)] The parent Specification disclosed a vacuum tin &c. having a cavity in the body or lid covered by a thin membrane which was ruptured by depressing it and the vacuum in the tin &c. was thus destroyed.

[Class 37.] Magnetic - induction testing - apparatus for determining the physical properties of materials, such as the presence or absence of non- metallic parts, cracks, or other flaws, or for determining the crystal structure of iron, or the identity of alloy constituents, has the turns of its primary inducing coil arranged so that when energised its flux density values vary from the centre of the coil along its longitudinal axis and at the same rate in both directions. The apparatus comprises a primary coil and three coaxial secondaries. In order to effect the desired flux distribution, the secondary coils 11-13, Fig. 2, are connected in turn by switches 100-102 to oscillographs 15-17 the disposition of the coils with respect to the primary 10 being modified by altering the number of winding turns as required. The length of the secondary 12 may be altered without altering the number of turns, or it may be rewound with a different number of turns. Balance between the secondaries 11, 13 and primary 10 may be effected by redistributing the turns of the primary, the secondaries being balanced with respect to each other as regards their output. All of the corrections are determined by the phase coincidence of the primary and secondary currents. Fig. 5 shows a coil construction comprising the primary winding 10 and secondaries 11-13, a displacement of some of the windings being shown at W. The coil together with voltmeter, ammeter, switches and rheostats, is built into a testing unit adapted for effecting the known differential, null and direct testing operations.

The grid is preferably flared at one end and may have a collar attached which may be joined to a flange on a sheet-metal cone 12 which may be integral with the ring 13. The ring 13 may have one or more annular bosses 14 to stiffen the support and yet allow radial expansion to relieve strains on the glass. The anode preferably extends beyond the seal between the retaining sleeve 15 and the bulb to protect it from electron bombardment. In manufacture the assembly except for the electrodes themselves may be mounted on a jig, Fig. 2 (not shown), whilst the two bulb portions and the ring 13 are being sealed together. The cathode is then attached to its lead wires, the grid to the cone 12, and the anode is put inside its retaining sleeve; the brazing rings 16 are heated to seal the anode to the sleeve.

Classes 68(i) and 85 [Also in Group XXX] When a dirt band occurs in a mineral seam and it is desired to mine said dirt and 'stow it directly in a goaf without taking it to the surface, the dirt band is cut out by a machine, such as an endlesschain cutting machine, the cutters of which are so disposed as to draw the dirt out clear of the face and deposit it on a rotating plate 21 positioned coaxially with and beneath the cutter chain drive sprocket to which it is connected. The dirt is retained on said plate by a guard 46 until a point at which it is desired that it should be ejected into a stowing machine rigidly connected to the mining-machine, the ejection being due to a plate 45 projecting over the periphery of said plate. The stowing machine comprises a high speed conveyer 33, the upper run of which is adjustably concaved downwards so that when the material leaves said conveyer it is flung upwardly and outwardly of the face. The drive for the conveyer is taken by a pinion from a worm wheel associated with said rotating plate, the pinion shaft being coupled to the drive sprocket shafts of the conveyer. The drives for the rotary plate and conveyer may be by separate motors. In the Provisional Specification there is described the use of a plurality of jibs which may be formed in one or two planes.
