Title: Improvements in and relating to web splicing devices
IPC: B65B41/16
Filed: 1966-01-28
Abstract: 1,140,401. Feeding webs. SCHWEIZERISCHE INDUSTRIE - GESELLSCHAFT. 28 Jan., 1966 [29 Jan., 1965], No. 3852/66. Heading B6B. A web splicing device for connecting the trailing and leading ends of two webs, 2a, 2b being fed successively to a machine (e.g. a packing machine 1), while maintaining predetermined spacing between centring marks, 3, on the webs, comprises a pair of rollers 13, 18, at least one 13 of which is displaceable by magnet 20 to press on the other, 18, for connecting the end (2a<SP>1</SP>) of web 2a to the leading end (2b<SP>1</SP>) of web 2b held in readiness at the mouth of the rollers. A sensing member 22a is adapted to give out a signal indicative of the passage of the trailing end of web 2a which signal causes energization of a magnet 35 to move one pin, e.g. 31, of movable pins 31-34 mounted in continuously driven disc 30, into a position where it actuates switch 37 to activate magnet 20 and thus join the webs. Disc 30 is driven synchronously with the passage of centring marks, 3, on the web 2a. A moved pin e.g. 31 first actuates switch 37 and then switch 38 to de-energize magnet 20. Return member 39 moves the pin back into an inoperative position as the disc 30 rotates, The two rollers 13 and 18 are directly connected by a driving belt 21. A table 12a, 12b may be arranged upstream of each roller 13, 18 to permit preparation of the leading end of the new web for joining, e.g. by an adhesive strip (24, Fig. 2). A tensioning device 7, 8, 9, 10 and 11 may be provided. Adjustment of displaceable roller 16 changes the size of the loop in web 2a and thus adapts it to the spacing between centring marks 3. A brake 23a prevents web 2a from running backwards.

Title: Improvements relating to methods of and apparatus for controlling the course of metallurgical processes
IPC: G01N21/72
Filed: 1954-02-12
Abstract: 778,407. Electric indicating systems. MACPLANCK - INSTITUT FUR EISENFORSCHUNG, E. V. Feb. 12, 1954 [Feb. 13, 1953; Feb. 16, 1953], No. 4223/54. Class 40 (1). [Also in Groups II and XL (b)] In supervising metallurgical processes in which flame is evolved, e.g. the dephosphorization of steel in a converter, a continuous measurement is made of the ratio of two characteristic spectral ranges of the flame spectrum. This process makes use of the change of spectral composition of the flame as dephosphorization progresses to determine the point in the dephosphorizing period at which a sudden change in the ratio takes place. A separate measurement of bath temperature is also made at this point and from a series of curves determined empirically and relating phosphorous content to bath temperature for various further blasting periods the further blasting period to be used is determined. Fig. 1 shows a pair of prism monochromators I, II, each of which is set to transmit a narrow band of radiation of a different wavelength. 4020 Š and 7200 Š are suggested. The intensities of the radiation from the two slits are compared by means of photo-multiplier tubes SEV1 and SEV2 connected in a differential circuit as shown. An optical wedge is provided in the right-hand radiation beam and this wedge may be adjusted so that meter I reads zero when the position of the wedge, as indicated on the scale Z gives the ratio of the two intensities. A nicol prism may be used instead of an optical wedge. A pyrometer is described for determining bath temperature. As shown (Fig. 5), a radiation sensitive device such as a photo-electric cell or thermocouple 8 is situated at the end of a tube 14 through which radiation enters. A filter 15 is provided in front of it. A blast of compressed air or other suitable gas is supplied to the outside of tube 11 which it enters through aperture 13 to prevent heated matter entering the pyrometer. Cooling water is circulated through the double jacket 18 of the pyrometer.
