In a rectifying system comprising for each phase of the alternating current input a plurality of electrically parallel rectifiers and associated electrically parallel current conductors, all of the said conductors being physically parallel, a further conductor in the form of a closed rectangular loop electrically insulated from the said current conductors, having two sides parallel to and close to the two laterally outermost of the current conductors, the other two sides of the loop being perpendicular to the current conductors, is provided so that induced currents in the loop will cause the inductance of each current conductor to be modified in a manner tending to equalize the currents in the said parallel current conductors. In order to adjust the current balance or to vary the proportion of the current carried by each of the parallel conductors the loop 7 may include a resistor 10 (which may be variable), may be moved in relation to the conductors, or may be varied in size. Rectifying branches may be paralleled in groups of more than two, and more than one closed conductor loop 7 may be provided. In a modification, the closed loop 7 may be arranged inside the loop formed by the two parallel branches of a pair (Fig. 2, not shown), in order to balance the two branch currents.

Abstract: 738,302. Feeding articles to wrapping mechanism. ROSE BROS. (GAINSBOROUGH), Ltd. Nov. 12, 1953 [Nov. 18, 1952], No. 29097/52. Class 94 (1). [Also in Group XXX] A wrapping machine having article-receiving pockets, e.g. pockets in an intermittently-rotating wrapping wheel, comprises a conveyer for feeding the articles toward the pockets, means for transfering the articles in succession from the conveyer into the pockets, a vibratory device for feeding a continuous succession of articles to the conveyer, means associated with the conveyer for removing surplus articles fed thereto, and a device adapted to detect the absence of articles from the conveyer and upon such detection to render the wrapping machine inoperative. As shown, sweets 11 are fed from a vibrating feed device 12 down a shoot 13 to a belt conveyer 14 which carries them (normally in close single file) along a guide channel 16 to a discharge station where they move in succession into a channel 17 from which they are fed into the pockets of a wrapping wheel 18 by a reciprocating pusher 21 of known kind which is caused to dip during its return stroke. A pivoted feeler 22 which normally rests on the sweets passing along the channel, has an arm 23 which operates a micro-switch 24 to stop the machine temporarily if a gap occurs in the file of sweets. A rotary brush 26, driven by a motor 28, is arranged to sweep surplus sweets from the conveyer into a container 27. The device 12 is of the kind in which the sweets are fed upwardly from a circular container along a spiral path 29 leading to the shoot 13. An auxiliary vibrating feed device, having a discharge channel 32, is provided for supplying sweets to the container from a hopper 33 and is controlled by a micro-switch 36 operated by a feeler 34 in the container to maintain the sweets therein at a predetermined level.

Classes 123(2) and 123(3) A water-tube boiler fired with a byproduct gas such as blast-furnace or coke oven gas and with a richer fuel such as oil, the fuels being used singly or in combination, comprises a steam generating tube lined, vertical furnace 10 having a top outlet into a lateral gas pass 16 locating a double bank of generating tubes 23 extending between a water drum 20 and a steam and water drum 22. Positioned in the upper part of the furnace across the outlet to the pass 16 is a superheater 30, the tubes of which extend downwardly to the rear furnace wall 13 at a level below that of the drum 20. In the front wall 11, at levels below the lower ends of the tubes of the superheater 30, are disposed two rows of combination oil and gas burners 40, 41 and above these rows opposite the said lower ends is located a row of oil atomizing burners 52.
