Filed: 1957-02-08
Abstract: 880,375. Measuring bridges. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 6, 1958 [Feb. 8, 1957], No. 4428/57. Class 37. [Also in Group XXXVIII] An anti-hunting arrangement for an automatically balanced bridge circuit comprises means for pulsing the balancing motor when the unbalance current is below a predetermined value. As shown (Fig. 1) unbalance between the sliders of potentiometers P4, P5 energizes centre stable relay CSR, followed by relay P01 or P02, depending on the direction of unbalance, thereby producing rotation of the balancing motor in the appropriate direction, and energization of slow-to-release relay P03 which opens its contacts to add resistors P1, R2 in the unbalance diagonal. When the unbalance is large, relay CSR continues energized, but when the unbalance is sufficiently small relay CSR falls, followed by P01, P02 and, after a delay, P03, so that resistors P1, R2 are again short-circuited by the contacts of relay P03. Relay CSR may then again be sufficiently energized to repeat the cycle, or the bridge balance is within the tolerance limits determined by rheostat P2.

Abstract: <PICT:1001499/C6-C7/1> A coating of superconductive niobium-tin alloy is produced on a chromium-nickel or tungsten wire the surface of which is oxidized or coated with glass, enamel, or ceramic.  As shown a vapour-coating apparatus comprises a niobium sphere 9 heated by electron gun 9 and a crucible containing tin which rests in resistance heater 10 which is also provided with a heat radiating screen, a vapour-stream director cylinder and a drip-trap (not shown).  Shutters 11 and 12 are provided to control the vapour sources and glow-discharge electrode 11 is provided for cleaning purposes.  The wire 4 is arranged on spools 5 and 6 the drive to which may be arranged so that wire 4 is rotated about its axis in addition to moving longitudinally. Wire 4 is first coated with niobium and then with tin, and further alternate layers may be deposited and the final layer of tin is sintered to produce a cohesive surface.  The wire may then be mechanically bundled and wound, for example, on to a former after which it is heated, by passing a current through it, to cause the vapour-coated layers to mutually diffuse and form a "hard" superconductive alloy.  Other methods of producing members at least partly covered with a superconductive alloy or compound are also described (see Division H1).

Abstract: 230,048. Blockx, (veuve Baichez), J. Feb. 28, 1924, [Conventon date]. Miniature and hand-power looms. - A device for making, ornamenting, repairing, &c. fabric articles, particularly hosiery articles, comprises a pair of hand-operated members 1, 2 pivoted together in the manner of a pair of scissors and carrying a set of needles 6 arranged alternately. A movable stop 8 is employed to define the position of the handles so that the needles lie in one plane. When the stop is moved aside the two sets of needles may be moved alternately to one side or the other of this plane. In using the instrument for darning purposes, a thread 9 is led between the separated needles and their position is then reversed, the process being repeated until the desired length of weft has been produced. The needles are then brought into one plane and inserted in the fabric to be darned as shown at 7 and the thread is led through the eyes by means of a threader 15. The lengths of thread between the needles are then engaged by hooks 16 supported in a handle 17 and the needles are withdrawn, thus leading threads through the weft to form a warp. The piece of fabric so formed is afterwards fixed at its other end by turning over the needle support. The sides of the patch so formed may be attached by an ordinary needle or by the multiple needle device. When used for patching worn fabric without holes the instrument is simply threaded into the fabric, the eyes threaded, the threads engaged by the hooks, and the needles withdrawn.

Abstract: 657,455. Machinery safety devices. METAL BOX CO. Ltd., PORTER, E. M. J., and CLARKE, C. S. Feb. 18, 1949, No. 4545. [Class 80(iv)] The starting handle 1 of a machine is locked in the " safe " position, against a stop 3, by a spring- loaded latch arm 11 of a bell-crank lever which is linked to the pivoted armature 7 of an electromagnet 4, the latch arm 11 cooperating with a pin 12 carried by the starting handle. The electromagnet 4 is energized upon the closing of one or more safety switch devices (which may be operated by guards, not shown), and, upon energization, the armature 7 moves the latch arm 11 and allows the handle 1 to be raised to start the machine. A second armature 15 carried by the pin 12 serves to retain the handle in its raised position, the electromagnet 4 being sufficiently powerful to hold both armatures 7 and 15 and prevent movement by normal means of the handle. When a safety switch is opened, or upon manual operation of a push button in the same circuit, the electromagnet 4 is de-energized and the handle 1 returned to the " safe " position under gravitational or spring action. Rapid de-energization of the electromagnet may be assisted by the provision of a small continuously - energized reverse winding, which may be connected in series with a resistor.

Title: Means for preventing the escape of gases from furnaces, especially in steam boilers
IPC: F23M11/02
Filed: 1925-02-24
Abstract: 230,061. Roucka, E. Feb. 25, 1924, [Convention date]. Air supply and draught, regulating.-To prevent leakage of gases through the brickwork of a furnace, interconnected means, operated by the pressures obtaining at the upper and lower parts of the furnace respectively, are provided for preventing the internal pressure from rising to an objectionable extent. The arrangement is such that under increasing load the flow of air or gases is controlled solely by the pressure-sensitive member in the lower part of the furnace while under diminishing load, when the pressure in the upper part of the furnace begins to approximate to the permissible maximum, the upper pressure-sensitive member acts to decrease the pressure. As shown, a damper 8 in the conduit supplying air to the ash-pit 4 is connected by a weighted rope 18 to the piston of a servo-motor 38, the valve gear 36 of which is operated by the vertioal movement of a bell 24, this movement being effected by variations in pressure, transmitted through a pipe 22, at the lower part 20 of the furnace. The normal position of the bell 24 and consequently the normal pressure to be maintained at the point 20 are adjusted by a spring 40 secured to the rocking-arm 28 and provided with means 42 for varying the tension; any increase in pressure raises the bell and causes the piston of the servomotor to descend, thus throttling the damper 8. Acting in conjunction with this regulator is a similar arrangement of servo-motor 48 and bell 52, the latter being operated by any increase in the normal pressure at the upper part 58 of the furnace to raise the piston 46 of the motor and so exert by tensioning the spring 44, an upward pull on the bell 24 to throttle the damper 8. A modification is described in which the pistons of the two motors 38, 48 are both connected directly, by means of a branched rope, to the damper 8. The regulators may be arranged to operate the flue damper 16 instead of the air supply damper 8.
