Abstract: 1,149,567. Transformers and reactors. GENERAL ELECTRIC & ENGLISH CO'S Ltd. 21 Sept., 1967 [24 June, 1966], No. 28519/66. Heading H1T. Cooling ducts 10, 11 disposed through the winding assemblies 7 of transformers, chokes and the like are so positioned that in any plane perpendicular to the major axis of the casing 1, and including the windings, the contour extending round the outer peripheries of the windings is of substantially the same shape as the casing as seen in transverse section. Thus, as shown, in a three-phase transformer two sets of four tubes 10 of, e.g. synthetic-resin-bonded paper, are disposed in each winding assembly 7 on opposite sides of a C-shaped core limb 6, the axes of the tubes in each set being parallel to define two planes mutually at 155 degrees, further tubes 11 of smaller diameter than the tubes 10 being disposed one on each side of the three outer tubes 10 in each set, to define planes at 12 degrees to the planes of the tubes 10. Thus the contour embracing the outer peripheries of the windings in a plane perpendicular to the major axis of the casing, is substantially circular, the same as the transverse-sectional shape of the casing (Fig. 2, not shown). The three C-shaped core limbs 6 are symmetrically disposed about the major axis of the casing, and the axes of the ducts run parallel to this axis. The casing is filled to just above the level of the tops of the windings with a cooling liquid, e.g. a fluoro-chemical liquid, the rest of the space being filled with an inert gas, e.g. SF 8  or nitrogen, at atmospheric pressure. Cooling liquid circulates through the ducts by convection during operation of the device. The volume of cooling liquid required is reduced by the use of shaped filler members 16, 17, 19 of, e.g. aluminium-loaded epoxy resin. The casing comprises a cup-shaped portion 2, between the hollow walls of which cooling water is circulated, and a lid 4 secured thereto. The core structure is supported from the lid by steel bands 14, and is clamped between supports 12 by longitudinally-extending rods 13. In a modification the ducts 10, 11 may be replaced by liquid-absorbent wicks.

Agglomerating processes.-Metallurgical slimes such as those resulting from leaching processes in which fine ores are to be sintered are added to the hot returns of the sintering-apparatus so as simultaneously to dry the slimes and quench the returns. For example, in a plant for treating iron pyrites, ore from the burners is classified into sands and fines. The sands are leached and treated in sintering-apparatus, which may be of the Dwight-Lloyd type, and the hot product is passed over a grizzly from which the oversize is conveyed away for subsequent smelting, while the undersize which may be partially quenched with water, is dumped into a bin. The fines from :the classifier are passed through thickeners, diluted with water, and sprayed on to the undersize sintered material. The product with the adhering dried slime is again passed through the sintering-apparatus.
Patent GB-293905-A (GB)
Abstract: 293,905. Comley, C. W. A. Jan. 14, 1927. Divided on 293,883. Ticket punches. - A ticket punch is adapted to issue a ticket from a supply roll punched according to the fare, the stage and the class of ticket, and counters add the number of tickets at each fare, class or stage. A spring-returned pivoted lever 84, Fig. 1, when forced towards a fixed hand grip 86 on the frame lowers a plate 74 controlled by a full stroke pawl 89 and carries a pawl 70 pivoted at 700 into engagement with one of four pins on a pinion 66, Fig. 1, so as to rotate a shaft 63 and cams 64 so as to depress and raise a frame consisting of two side plates 33 with L-shaped cross-bars 35, 36 which actuate the puncher. Thereafter a pawl 79 on the plate 74 engaging one of three pins 81 on a disc fast to a three-toothed disc 21 turns the latter to feed another length of strip into position for a fresh ticket. Long overhangs on the pawls 70, 79 lock against the corresponding pins and prevent undesired movement of the parts. The supply of strip on a spool 18 fits on a hub 17 with two internal diameters which afford a shoulder to lock a headed split pin 96 on the cover 93 of the supply roll casing 91, which latter has a flared side 92 dovetailing in a fixed guide 90 on the frame plate 16. The ticket has three fields 115, Fig. 6, for fare values, 116 for stages, and 117 for class of ticket. Twelve fare value punches 30 work in a guide plate 113 and the base plate 13 and have heads formed to engage positively each in a rocker 46 pivoted on a crossbar 45 and having pivoted to it a tumbler 47, thrown, each by its spring 49, outwardly to thrust the manual end 26 of its key lever through an aperture in the casing. The key levers are pivoted on a pair of parallel bars 24, 25 and alternate above and below, and are adapted, when depressed, to throw their tumblers 47 into engagement with the cross-bar 35, in which position they are held for actuations by a spring-controlled yoke 39, 40 pivoted on studs in the casing, one of the arms having an extension to wipe against a fixed stop to prevent disengagement of tumbler and cross-bar during operation. The tail of the tumblers engage extension fingers on slides 112, the upper ends of which are prolonged to coact with one-way actuators 111 for appropriate counters 110. The second cross-bar 36 on the reciprocating frame engages the grooved head of a punch 50 for the " stage " which works in a carriage 51 which can be positioned by means of a screwed spindle 52 and an external crank 53. A set of five classification punches 60 are connected one at a time by a coupling piece 61 to a grooved cross-bar 59 on the reciprocating frame; selection being made by a hand lever 612, the inner forked end of which engages a stud 610 on the coupler 61. A tray 105 has receptacles 106 for the currency punchings and 107 for the classification group, and the " stop " punchings are collected in a receptacle 107 attached to the carriage 51. Instead of punches, impression type heads may be fitted to the various plungers.

Abstract: 1478965 Radio receiving systems COMMUNICATIONS PATENTS Ltd 13 June 1974 [21 June 1973] 29522/73 Heading H4L A television receiver is provided with rejector means for attenuating either unwanted signals lying between the principal modulation components of a wanted television signal comprising those components grouped around multiples of the line scanning frequency either side of the carrier wave frequency, see Fig. 2 (not shown), or the wanted signals, to produce a signal which, when combined with a delayed version of the received signal, provides a signal in which unwanted components are minimized, the rejector means operating at i.f. As shown, television signals from IF amplifier 3 are divided at 5 and supplied via a delay 9 to a combiner 8 and via rejector means 6, which provides an output consisting of signal components which lie between the principal modulation components of the wanted signal, to the combiner 8. Delay devices 9 and 10 provide a phase adjustment whereby the unwanted signals are reduced at combiner 8. The rejection means 6 comprises means for establishing two signal paths, means for delaying the signals through one path with respect to those through the other by approximately one scanning line and means for combining the signals from the two paths so that the wanted components are minimized, forming what is effectively a comb filter. In the rejector means of Fig. 2 (not shown) for the case where the interfering and the wanted signals have the same line scanning standard, the IF signal is supplied to a splitter and then supplied via a delay of approximately one scanning line to a combining device and by the other path through an incremental delay to the combining device. Alternatively, the incremental delay may be connected in series with the one line delay. The incremental delay corresponds to the spacing of the modulation components of the wanted signal, and those of the unwanted co-channel signal.
