Abstract: 1299877 Making pipes CIBA-GEIGY AG 3 Nov 1969 32908/72 Divided out of 1299873 Heading F2P [Also in Division B8] In a continuous pipe-making process for fibre-reinforced plastics pipe, an air impervious former T is continuously produced on an axially stationary rotatable mandrel Figs. (4), 4A, 4B, (4C and 4D) and may remain as an integral liner of the completed pipe. The leading end of the pipe P is sealed with a plug C and compressed air is introduced into the pipe through the end 50 of the mandrel which is sealed at B relatively to the advancing pipe, so that fluid pressure, which is exerted between the mandrel and plug seal C, drives the pipe forwardly through the winding heads I 1 , I 2  and I 3  and resin applicators J, J 1 , J 2  and J 3 . The fibre and resin build-up is applied at these locations as described in Specification 1,299,878. As shown, the former T is produced by applying epoxy resin from head 208 to strips d of tissue paper and spreading the resin evenly across the strip by means of a moving, flexible endless steel doctor blade 188. Heater 310 (Fig. 2) causes the resin to soak through the strip d before winding. The strips d are wound on flexible endless non-stick belts 104 and 106 (Figs. 4A and 4B) forming a moving sleeve carried along, in sliding contact with sleeve 102, by the advancing pipe. Each band of strips d is partially cured by heaters 312, before leaving the belts 104 and 106. Before the fibre and resin build-up is applied, the former passes through a cooling device 316 (Fig. 1A). In another form (Figs. 29-31, not shown), a strippable tube, lining the former T, is made of gummed paper tape, as described in the parent Specification 1,299,873. The use of a non- strippable tape of resin-impregnated glass fibre is additionally disclosed. A thick resin liner may be put under compression by winding on a glass tape at a waisted portion of the mandrel. The former (T<SP>1</SP>) may be removable from the completed pipe.

Title: Improvements relating to the catalytic desulphurisation of petroleum hydrocarbons
IPC: C10G45/28
Filed: 1949-12-29
Abstract: Petroleum hydrocarbons are hydro-catalytically desulphurized by contacting the hydrocarbons in vapour form in admixture with hydrogen with a finely divided fluid dehydrogenation-hydrogenation catalyst, at a temperature and pressure such that the dehydrogenation of naphthenes is effected to an extent not substantially in excess of that required to provide sufficient hydrogen to convert organically combined sulphur contained in the hydrocarbons into hydrogen sulphide and to maintain the necessary pressure in the reaction zone.  The treated hydrocarbons are continuously removed from the reaction zone, hydrogen sulphide and a hydrogen-rich gas, which is recycled, are separated, and spent catalyst is continuously removed from the reaction zone and passed to a regeneration zone from which it is recycled to the reaction zone.  The catalyst may be a mixture of oxides of cobalt and molybdenum, or chemical compounds of cobalt, molybdenum and oxygen, or mixtures of both types; cobalt molybdate or alumina is specified.  The process may be carried out at a temperature of 750-800 DEG F. and at a pressure of 50-200 p.s.i.  The treatment of wax distillates, gas oil, aromatic extracts and other feedstocks boiling below 350 DEG C. is described. Specification 669,551, is referred to.

Title: Improvements in or relating to machines for forming tubes of paper or the like
IPC: B31C1/00
Filed: 1920-11-26
Abstract: 180,707. Wade, H., (National Paper Can Co.). Nov. 26, 1920. Paper tubes.-A machine for winding paper sheets under tension on to a rotating mandrel, to form open-ended tubes for making cartons, comprises a free-running endless chain band 3, Fig. 6, between which and the driven mandrel 2 the paper sheet 6 is wound under tension and pressure. The paper may be, sprayed with hot paraffin wax by jets 120, 121 as it is fed to the mandrel. The winding-head 11 of the machine is shown in longitudinal section, on a smaller scale, in Fig. 3. The chain band 3 passes around fixed rollers 35 and two movable tensioning-rollers 36, 37, which are also yieldingly supported by springs 53, 63 to enable the band to accommodate itself to the increasing diameter of the tube during winding. Cam-plates 60, one at each end of the mandrel, are automatically rocked at appropriate moments to adjust the rollers 36, 37 and tension or relax the band 3. The mandrel 2, which is replaceable by others of different sizes for winding tubes of different diamet-srs, is driven by the main driving-wheel 20 through a pinion 22 and mandrel spindle 14. The mandrel in the machine described makes twelve revolutions to one by the wheel 20. The first four revolutions wind the paper strip on to the mandrel; during the next four, the layers of paper are consolidated by the band pressure and drag, and the surplus wax is expressed. The tension of the band is then released by a tappet device on the wheel 20 causing displacement of the cam-discs 60 so that during the last four revolutions a stripper cylinder 4 may be forced automatically between the band and the mandrel to remove the tube. The links 41 of the band are curved so that. they conform to the curvature of ',he mandrel; the tops and bottoms of the links nay have different curvatures, as shown in Fig. 8<a>, to enable one band to be used for two different mandrels. The link pins 42 have conical ends 85, Fig. 8, to facilitate the entrance of the stripper cylinder between the band and the mandrel. The paper strip 6 is fed under tension by the feed-roller device described in Specification 180,972, and is guided between a. rocking plate 125 and a spring- pressed plate 117. At the time that the end of the strip 6 passes from the pension rollers, a tappet device on the drive-wheel 20 causes the longitudinal shaft 135 to be rocked and moves the plate 125 towards the plate 117 so that the paper strip is seized between the two plates, and maintained in tension during the final part of the feed.

Heading D1C A hosiery knitting machine controls the size of the stitches by first drawing loops between sinkers, without knitting, to form constant length loops, partly withdrawing sinkers to slacken the loops and then further operating the needles to knit. In operation, every other needle 31 knits normally a selvedge course, a second course is knitted normally, transfer nibs 43 and then extended to form welt transfer loops during the third course and normal knitting continues for the welt with an adjustable stitch cam 33 as in Fig.9. Stitch control then starts. A pattern drum raises segments 34, 35 of the cam 33 so that the needles 31 are lowered sufficiently to draw by not to knit (Fig. 17) and simultaneously the pattern drum releases a latch 63 (Fig. 21) so that the needles carry round a sinker cap 17 so that the sinkers 32 are fully inserted and the yarn 12 is laid across the top surfaces 46 (Figs. 4, 8, 14). As rotation continues the cap 17 partly withdraws the sinkers to slacken the loops, the cam segment 42 knits the loops and knitting continues. At the heel portion the cam segments 34, 35 are lowered for normal knitting and the first reversal of rotation causes the needles to carry round the sinker cap 17 to be engaged by the latch 63 so that normal knitting is resumed for the reciprocatory knitted heel portion. The pattern drum then resumes special knitting for the foot portion and then normal knitting for the toe portion.
