Filed: 1923-07-09
Abstract: 222,942. British Electrical & Allied Industries Research Association, Whitney, W B., and Wedmore, E. B. July 9, 1923. Sparking, preventing.-In order to minimize the injurious effect of sparking at the contacts of A.C. circuitbreakers, two or more pairs of break contacts in series are employed so adjusted as to separate in succession during, substantially, one cycle of the alternating current, when the circuit-breaker opens. The time-interval between the succession of breaks is adjusted to correspond, in the case of a single-pole circuit-breaker with a double break, to a half cycle of the alternating current. In the case of a three-phase circuit the circuit-breakers in the phases are timed in relation to one another also. As shown in Fig. 1, applied to a single-pole oil circuit-breaker with the usual main bridging contact 10 and auxiliary sparking contacts 12, the setting is such that the main contact 10 first leaves the fixed contacts 11 followed by the left-hand sparking contact succeeded by the right-hand sparking contact. In the arrangement shown in Fig. 4, a number of pairs of auxiliary contacts 12, 13 in series are adapted to separate in succession.

Title: Improvements in smelting of zinciferous ore
IPC: C22B19/00
Filed: 1951-07-27
Abstract: In a method of smelting zinciferous ore to produce zinc vapour capable of being condensed predominantly to massive zinc metal, a charge of the ore and solid carbonaceous reducing material is introduced into a furnace on to a body of slag which is heated to a temperature not greater than 1450 DEG C by an arc in contact with the slag and struck from an electrode terminating above the slag surface, the charge being composed of oxidized zinc ore containing (a) iron and at least one of the metals copper, silver and gold, (b) an amount of sulphur sufficient to form a matte with substantially all of the said metals and at least a portion of the iron, (c) an amount of carbonaceous reducing agent sufficient to reduce all the zinc oxide. The charge is delivered adjacent to the furnace side walls as a loose mass of discrete particles in such as way as to form a sloping bank terminating at the surface of the slag and out of direct contact with the electrode and arc. The heat necessary for smelting is imparted to the charge by radiation from the arc and through contact of the charge with the slag, the slag resulting from smelting being free from readily reducible oxides, except possibly for a proportion of iron oxide not sulphided by the sulphur constituent, before it comes into contact with the arc.  The sulphur content of the charge may be provided by residual sulphur in incompletely roasted sulphidic zinc ore or by addition of extraneous iron sulphide.  The amount of reducing agent used may be sufficient not only to reduce the zinc oxide but also to reduce to iron any non-sulphided iron oxide in the charge, whereby a body of molten iron is formed underlying the slag and matte.  The zinc vapour evolved together with any cadmium and lead is condensed to massive zinc metal.  The cadmium and lead may be separated from the zinc in a fractionating column.  Specifications 601,246, 601,247, 620,644, 648,529 and 657,205 are referred to.

Title: Improvements in or relating to apparatus for regulating forced-flow tubulous steam generators
IPC: F22B35/10
Filed: 1937-06-28
Abstract: 479,416. Forced - flow steam boilers. SIEMENS - SCHUCKERTWERKE AKT.- GES. June 28, 1937, No. 18013. Convention date, June 26, 1936. [Class 123 (ii)] In a forced - flow tubulous steam boiler at least one of a number of tubes through which the working medium flows in parallel from a common supply conduit 7 to a common outlet conduit 8 has an independent separator 11 in the length of the tube between the common conduits and a regulator 12 for independently controlling the supply to the tube. The supply of heat or of working medium to conduit 7 is controlled preferably automatically in accordance with the quantity of liquid in the separator so that with an increase, the heat is increased or the feed supply reduced and vice versa. By setting valve 12 to increase the throttling effect the flow through the remaining tubes is increased and the outlet temperature reduced ; also the ensuing fall of liquid level in the separator results in a reduced heat supply with a further reduction in temperature of the superheated steam.

Title: Improvements relating to electric meters

Abstract: 274,134. British Thomson-Houston Co., Ltd., (Assignees of Kinnard, I. F., and Pratt, W. H.). July 12, 1926, [Convention date]. Induction motor meters; resistances, measuring.-An integrating meter of the induction type is so arranged that the flux of one of the driving magnets constitutes the sole damping means. The flux cutting the armature disc 14 due to the potential winding 11 is increased, for example to five times its normal value, the flux due to the current winding 13 being reduced, for example to 15 per cent of its normal value, giving a driving torque of about 65‹ normal. Under such circumstances the braking due to the increased potential flux is sufficient without a separate brake magnet. In order to obtain this increased flux, the air gap A may be increased to about 0.125 in., the normal value being 0.046 in., and the air gap B in which the disc rotates may be decreased to about 0.170 in., the normal value being 0.218 in. An armature disc having a resistance somewhat lower than usual may be employed, for example a copper disc 0.035 in thick may be employed in place of an aluminium disc 0.022 in. thick, the extra weight counteracting the increased tendency to vibration due to the increased potential flux. The driving torque of such a meter at constant power factor is proportional to EI, where E is the pressure and I the current, and the braking torque is proportional to E<2>, the speed therefore being proportional to EI/E<o> = I/E. By connecting in series with the winding 13 a resistance varied by a mercury manometer in accordance with the difference in pressure between the two sides of a nozzle in a fluid flow meter, the instrument serves to integrate the I conductance -, which is proportional to the flow E to be measured. In place of the variable resistance, the mercury transformer arrangement described in Specification 214,632 may be employed The meter may be employed on a constant-pressure circuit as an energy or amperehour meter, or that portion of the potential flux: which produces damping may be maintained constant with ordinary variations of voltage by passing a portion of the flux through a saturated magnetic circuit.
