Title: Improvements in and relating to regulating systems for thermionic devices
Inventor: KEARSLEY WILLIAM K
IPC: H05G1/16
Filed: 1928-03-14
Abstract: 287,557. British Thomson-Houston Co., Ltd., (Assignees of Kearsley, W. K.). March 24, 1927, [Convention date]. Regulation, automatic.-The space current in a R÷ntgen-ray or other thermionic tube 1 is maintained constant, on variations of the supply voltage or of the residual gas in the tube, by means of a thermionic control tube 21 with means such as a grid 24 for controlling the current from its cathode 22 to its anode 23, the potential of the grid 24 being controlled in accordance with the space current in the tube 1 and the current through the tube 21 controlling the heating current to the cathode 2 of the tube 1. The space current of the tube 1 is supplied from the mains 10 through a transformer 12 with secondary windings 16, 17 in series with a non-inductive resistance 18 shunted by a condenser 19. The grid 24 is connected to the cathode 22 through a biassing battery 35 and a part of the resistance 18, the current through the resistance 18 producing a potential on the grid 24 opposing the battery 35. When the space current in the tube 1 rises above a certain value in any half-wave impulse, the grid 24 becomes positive and a current then passes from the mains 10 through a non- inductive resistance 31 and through the tube 21. The increased potential drop in the resistance 31 due to increasing current through the tube 21 reduces the current supplied to the cathode 2 through a transformer 7, the electron emission from the cathode 2 decreasing to maintain the space current in the tube 1 constant. In a modification, the resistance 18 is replaced by an inductance and the battery 35 by a transformer connected to the mains 10. The tube 1 is operated at saturation current and may be of the kind described in Specification 14892/13, [Class 39 (1), Electric lamps, Arc &c.]. Specifications 210,743, and 223,921, [Class 39 (i), Electric lamps, Arc &c.], also are referred to. Vacuum tubes; low pressure metallic-vapour apparatus.-The thermionic control tube 21 operates with gas-ionization and, after being exhausted and freed from moisture, is filled with a vapour such as that of mercury or a gas such as argon at a pressure of 5.5 cms. The grid 24 may surround the anode 23. Reference has been directed by the Comptroller to Specifications 275,784 and 292,001.

Title: Improvements relating to hydraulic control of brakes
Inventor: RYE JOHN LEONARD
IPC: B66D1/08
Filed: 1957-03-12
Abstract: 877,165. Hoist drum brakes. KEELAVITE CO. Ltd. March 12, 1958 [March 12, 1957], No. 8117/57. Class 103 (1). A power transmission system incor-. porates a motor, a brake arranged to act on a member driven by the motor, control means operable to cause movement of the motor in either direction and capable of controlling power (the driving power) delivered through power delivery means to drive the motor, at least one anchoring member movable in two directions from a neutral position, each of which directions corresponds respectively with a direction of movement of the motor, into contact with an appropriate fixed part to transmit to that part the reaction upon the brake during braking, and brake control means arranged to receive from the power delivery means operating power to release the brake and automatically effective to allow release of the brake upon movement of the anchoring member from its neutral position only in that direction corresponding to the direction in which the motor is urged by the driving power applied to it. In the apparatus shown, a hoisting drum 1 around which is wound the normal hoisting cable 2 supporting a load 4, the drum 1 is arranged to be driven in either direction through transmission mechanism indicated at 5 by a reversible hydraulic motor 6 having fluid inlet and outlet passages 7 and 8 either of which can be connected by a piston-type control valve indicated at 9, to a source of fluid under pressure at 10. Freely mounted upon the shaft 18 of the drum 1 is a movable anchorage member 19, to which are pivoted at 20 a pair of brake shoes 21, 22, arranged to act upon a brake drum 23, rigid with the drum 1. The lower end of the member 19 is connected through rods 43 to a further piston-type slide valve having chambers in communication with passages 7 and 8 connected to the reversible hydraulic motor 6. A conduit 51 leads from the latter piston-type slide valve to an hydraulic cylinder 35, wherein fluid pressure may act upon a piston 36 to release the brake shoes against the pressure of spring 27. If the lifting torque exceeds any load applied to the drum 1, through cable 2, the drum and hence the movable anchorage member 19 will rock, so that the projection 37 engages the adjustable stop 39, as shown in Fig. 3. The valve 44 is therefore moved to admit fluid to the cylinder 35 to release the brake. This arrangement avoids the condition wherein, if a light load is being handled, it is necessary to use an hydraulic pressure much greater than that necessary to lift the load so that the hoisting operation starts with a jolt.

Title: Secondary cooling of continuous steel castings
IPC: B22D45/00
Filed: 1975-02-26
Abstract: 1500810 Continuous casting CONCAST AG 26 Feb 1975 [28 Feb 1974] 8121/75 Heading B3F  If the cross-section of a continuously cast steel strand 1 or the steel analysis or both is (are) changed, the secondary cooling is adjusted by changing the distance from the strand surface of coolant spray nozzles 3-8, and the consequential changes in surface area sprayed and included angle of the spray fan (and therefore of the cooling effect) are compensated for by varying the inter-nozzle spacing 19 of two or more nozzles located side-by-side across the casting. The coolant pressure may be kept constant and adjustment of the nozzles 3-8 is effected so that the ratios of strand width to nozzle distance 18 and to inter-nozzle spacing 19 remain constant if the width is changed. The spray nozzles, 3-8 as shown are each mounted on a nozzle pipe 9 between adjacent guide rollers 11 or adjacent rollers 12 on one or other wide side of a casting 1, there being four such banks 3-5 or 6-8 of nozzles to each side of a guide apron segment of four pairs of rollers 11, 12, Fig. 1 (not shown). In a bank, two nozzles 3, 5 or 6, 8 are adjustable by a linkage, e.g. for nozzles 3, 5, a linkage 22. As shown for the nozzles 3, 5, the pipes 9 are mounted on guide rods 29, 30 so that the two nozzles can be moved to positions along respective paths 15, 16, the end positions 44, 45 being those for a wide casting (2), Fig. 3 (not shown). At the same time the middle nozzle 4 is moved up or down by the linkage 22 in the line of the side nozzles 3, 5, parallel to the casting wide side 41. For wider castings there may be four or five nozzles, instead of three, to each bank. If the change of strand cross-section is not symmetrical about the casting axis as indicated in ghost lines, the adjustment positions of nozzles 3, 5 will not lie in lines 15, 16 between the point of intersection of a median-perpendicular 40 with the strand surface 41 and the extreme nozzle positions 44, 45. If one narrow side of each cross-section, for example, is always in the same plane, the adjustment positions for each nozzle 3, 4 and 5 would lie on lines extending from the near edge of the narrow side to the extreme positions of the nozzles. The positions of the nozzles 3-5 are changed by a drive 34 rotating a shaft 31 which turns a lead screw 25 to raise and lower the nozzle 4 by way of its nozzle pipe 9 and, because of the linkage 22, the nozzles 3 and 5 also. In the later, lower region of the secondary cooling zone only part of the slab width may be sprayed.

Abstract: 400,238. Heat treating magnetic material. SMITH, W. S., Benchams, Newton Poppleford, Devon, GARNETT, H. J., Lymne, Solefields, Sevenoaks, Kent, and RANDALL, W. F., Stretton, Queensmead Avenue, Ewell, Surrey. March 18, 1932, No. 8157. [Class 72.] In the heattreatment of magnetic material in coil form in an annealing-box, within which the material is cooled in air, the charge is arranged in the annealing- box so that the inner coils of the material are cooled more rapidly than the outer coils. The coil D is arranged in an annular annealing-box so that the inner part of the coil is nearer the inner wall B of the box than the outer part of the coil is to the outer wall A of the box, and refractory material E is packed round the coil D. The box is provided with a lid C. After the box has been placed in the annealing furnace where the coil is heated to the required temperature, the box is removed from the furnace and placed on fire bricks or rests on feet or legs F and is allowed to cool in air. The cooling may be accelerated by placing a vessel filled with water in the central hole in the box. In a modification, the charge may be arranged in the same manner in an ordinary annealing box and a smaller cylindrical box of an external diameter slightly less than the inner diameter of the coil is placed inside the core. For cooling the smaller vessel may be filled with water or a third box filled with water or other cooling medium may be placed inside the inner box.
