Title: Arrangement provided with a discharge flash tube
IPC: G03B7/16
Filed: 1970-05-29
Abstract: 1307244 Flash discharge circuit PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES LTD 29 May 1970 [3 June 1969] 25942/70 Heading G1A [Also in Division G2] The duration of the flashing of a discharge flash tube 1 is dependent upon the foot candle value of light reflected by the object (to be photographed) onto a photo-sensitive element 14 said photosensitive element controlling the operation of a pair of thyristors 8 and 11. When the flash tube is ignited it receives current from a supply capacitor 3 and the current flows through the windings of the transformer 2 thereby charging a capacitor 17. The speed in which the capactor 17 is discharged is dependent on the photo sensitive element 14 whose resistance varies with the value fire light intensity received. The instant that the thyristor 8 becomes conducting is similarly dependant. Once thyristor 8 conducts the resistances 9 and 7 are such that the further thyristor 11 also starts to conduct, and the thyristors thereby discharge capacitor 3 until the tube 1 is exinguished.

Abstract: 473,800. Making helical tubes. WILLIAMS, W. P. (American Rolling Mill Co.) Sept. 29, 1936, No. 26403. [Classes 83 (ii) and 83 (iv)] In forming a helical lock seam tube, a strip is corrugated longitudinally, wound into a helix with flanged edges interlocked and the seam is then flattened. The strip is fed between driven corrugating rolls which flange and bead the strip. It then passes between a mandrel and female helical sizing member mounted on a turntable and is formed into a helical tube with the flange and bead interlocked. Helically arranged rollers then flatten the seam. In the apparatus shown in Fig. 3, rolls 2 driven by an electromotor 4 progressively corrugate the strip from the centre and form the edge bead and flange. The strip then passes to a turntable 15 carrying a mandrel 13 and an internal helically corrugated die 17. The strip is bent into helical form between the die 17 and the mandrel with the seam interlocked. Lubricant from a pipe 21 is circulated through the die 17. Rollers 28, 29, Fig. 8 (not shown), are mounted on leaf springs adjustable by a screw 54, and rollers 34, 36 helically arranged co-operate with rollers 37 adjustable on the mandrel to bend over the seam. A roller engaging the edge of the strip, Fig. 28 (not shown), moves a pointer for indicating camber of the strip. Should excessive camber be indicated guides on the feed table are adjusted to effect compensation. The mandrel 13 and the die 17 may be smooth walled for forming non-corrugated tubes, side slip of the strip being prevented by guide 24 on the mandrel. Soldering.
