Abstract: 246,209. Parsons, Sir C. A., and Rosen, J. Oct. 21, 1924. Transformers.-In cooling dynamos, transformers, &c. by passing air in a closed circuit through the dynamo and over a cooler a portion of the cooler is cooled to a lower temperature than the remainder, below the dew-point, so that condensation of water-vapour is localised in that portion, which is provided with means for removing the condensate. In the arrangement shown air is circulated by a fan b through a dynamo a and trunks d, e, in one of which are arranged main coolers f which cool the air nearly to dewpoint. and an auxiliary cooler i which is maintained below dew-point, condensates escaping through a trap k. Only a small portion of the air passes over the cooler i. In a modification the cooler i is formed as part of the main cooler, through some of the tubes of which passes cooling liquid at a lower temperature than that passing through the remainder.

Title: Process for the resistance welding of a corrugated strip to a base strip, sheet or tube
IPC: B23K11/00

Abstract: 998,071. Making heat exchangers; welding by pressure. H. KRESS. July 14, 1961, No. 25642/61. Headings B3A and B3R. In resistance welding a corrugated strip to a tube, strip or sheet, an electrode having radially arranged contact tips and the wall are moved so that the tips in turn engage the bases of the corrugations and spot-weld them to the wall. A strip 2<SP>1</SP>, Fig. 1, is corrugated by toothed wheels 3, 4 and fed through a guide 10 on to a tube 1 supported on an electrode 5. A base 7 is spot-welded to the tube by tip 6<SP>1</SP> of a rotatable star electrode 6, the tube and electrode are then rotated to a position so that tip 6<SP>1</SP> clears the corrugated strip and then the tube is held stationary. The next corrugation is compressed by the tip 6<SP>2</SP>, the tube is rotated backwardly until the correct base width is obtained and the base is spotwelded. The backward rotation may be eliminated if the electrode is lifted off the corrugated strip or by positioning the electrode so that the radius thereof passing through the weld point is offset in the direction of rotation of the electrode from the axis of the tube. In a modification also employing the offset weld position the strip 2<SP>1</SP>, Fig. 4, is corrugated by a lever 17 having an axially movable pin 19. In another embodiment corrugated strips are provided on a flat wall 20, Fig. 5, a pre-corrugated strip being fed and then welded by tip 23<SP>1</SP> of electrode 23, the electrode is then moved axially out of engagement with the strip, is rotated to bring the tip 23<SP>1</SP> into position 23<SP>11</SP> and is then moved axially into engagement with the strip. On further rotation the next tip 23<SP>21</SP> presses the next loop into the welding position above a roller electrode 22. The corrugated strip may be welded to a flat strip bent around a roller electrode which may rotate about an axis parallelto or at right angles to the axis of the upper electrode wheel.

Abstract: 619,890. Addressing &c. machines; cutting and delivery apparatus. LAMSON PARAGON SUPPLY CO., Ltd., and GARWOOD, V. W. Aug. 30, 1946, No. 26155. [Classes 100(i) and 100(ii)] In addressing or like machines wherein printing plates are fed in succession to printing position, a paper web is fed intermittently past the printing position and is printed while it is stationary and the printed web is cut into sheets when the web is stationary, two separate driving-mechanisms are provided each being driven from a printing-arm which reciprocates a printing-head in a vertical plane, one mechanism operating the web-feed and the other a guillotine cutter. Feeding forms &c. - A stationery pack is fed during the non-printing stroke of a rocking aim 5 carrying a printing-head, by pins on a sprocket carried by a chain driven by a gear 26 fixed to a shaft 21 rotated intermittently by a pawl 24 and ratchet 25 actuated by a rod 7 pivoted to a bracket 7c detachably connected to the arm 5. A detent roller 34 engaging a notched wheel 32 on the shaft 21 prevents movement of the feed mechanism during the printing stroke. The chain is adjustable bodily to suit the width of the stationery. A brake 90 prevents overrun of the chain drive. Sheet guides.-Printed stationery passes between guides comprising spring blades 10a fixed to a bracket 13, and co-operating blades 10b carrying screws 15 at one end such that on turning grooved nuts 14 engaging a bar 12, the blades 10b may be adjusted vertically. Cutting.-A guillotine cutter comprises a fixed blade 35 and a blade mounted in a carrier 43 actuated by an arm 53 rocked from a rod 7 acting through a ratchet and detent mechanism like that for the paper feed. The carrier 43 is slotted to engage a pivot pin 45 and a guide pin 49, whereby the blade has a draw-cut action. The whole of the cutting - mechanism is mounted on screwed spindles 39, 40 rotatable by turning a shaft 42 to adjust the mechanism to vary the length cut off. The web is prevented from moving during cutting, by spring-pressed pins 72 depressed by a bar 73 having spring plungers 75 engaging the pins. The bar 73 is carried by parallel links 74 and is raised by the arm 53 and pressed towards the paper by springs 74a. Delivering sheets.-Conveyer bands 83 pass over a roller and over pulleys 81a on a shaft 81 driven from a shaft 29; preferably, the bands travel slower than the paper so that the cut sheets overlap. The conveyer mechanism is adjustable with the cutting-mechanism and may be formed as an attachment carried by a base-plate 8. The Provisional Specification describes an upper, spring-loaded cutting-blade periodically released by a cam.
