Making tickets.-Apparatus for making tickets, each consisting of superposed layers gummed together to form a pocket enclosing a separate slip, comprises means for feeding a strip of cardboard to elements which print, punch, gum, fold, trim, and sever the strip: alternatively, three separate strips may be fed to the machine. As shown in Fig. 1, which shows a machine in which the strip is cut longitudinally to form two rows of tickets, the strip is fed from a roll 12 to printing rolls 15, 15<1>, 16, 16<1>, which print the parts 28, Fig. 3, forming the separate slips, and the edges of the parts forming the pocket. The strip then passes punching rolls 18, 19 which make holes 27, 27<1> and score round the edges of the parts 28. The strip then passes drying elements 21 to a scoring device 22 which scares the strip at 22<a>. Gum is applied on the margins 25 by a gumming device 24, after which the strip is cut down the centre by a cutter 29. The separated strips are then passed to the folding station 31 where first the outer portion with the parts 28 is folded on the central part, the other outer part being then superposed. The folded strips then pass to pressure rolls 34, edge trimming knives 35 the action of which severs the slips 28, and cutters 37 which cut the strips transversely along the ling 39. Fig. 4 shows the completed ticket with the inserted slip. In another form, the punching unit consists of reciprocating dies. and the blank is allowed to accumulate before and after passing through this unit. The blank is fed intermittently by reciprocating grippers 107, 114. Fig. 7b, the upper gripper 114 being raised and lowered by cam-operated levers 113. To ensure correct register during punching, the punching head is provided with fingers 119, Fig. 7<a>, mounted on a bar 118 which is adjustable by hand longitudinally of the blank to enable the fingers to engage perforations previously made. The apparatus for severing the tickets is synchronized in relation to the perforations by means of a differential device, shown in Fig. 8, in which a rotary knife 134 co-operating with a fixed knife 135 is driven from the shaft 122 through a differential gear, the planet carrier 136 being rotatable from a hand-wheel 140 to vary the phase of the cut.

Title: Improvements relating to metal soaps
IPC: C07C51/41
Filed: 1948-02-03
Abstract: Polyvalent metal soaps are prepared by reacting an alkali metal soap prepared from hydrogenated castor oil or the mixture of fatty acids derived therefrom or an alkali metal soap of 12-hydroxystearic acid with a water-soluble salt of aluminium, lead, calcium or zinc.  The hydrogenated castor oil may have an iodine value between about 1 and 15.  The alkali metal soap may be prepared by saponifying hydrogenated castor oil or the fatty acids derived therefrom with, e.g., sodium hydroxide.  In an example, hydrogenated castor oil is saponified by means of 50 per cent aqueous caustic soda, the sodium soap thus obtained is dissolved in water, the temperature of the solution raised to about 80 DEG  C. and sufficient aluminium sulphate solution added to react completely with the soap; the precipitated aluminium soap is washed, dried and ground to a powder.  According to further examples, lead and calcium soaps of hydrogenated castor oil are prepared similarly using lead acetate and calcium chloride in place of aluminium sulphate.  The polyvalent metal soaps are used in water-proofing compositions (see Group VIII).  The Specification as open to inspection under Sect. 91 relates to the production of the soaps of any suitable polyvalent metal by the above process.  This subject-matter does not appear in the Specification as accepted.
