Title: Improvements in or relating to packet making or other machines comprising intermittently rotatable discs or turrets
IPC: B65B11/32
Filed: 1946-11-04
Abstract: 618,306. Paper bags; packeting. DEARSLEY, G., and MOLINS MACHINE CO., Ltd. Nov. 4, 1946, No. 32677. [Classes 94 (i) and 94 (ii)] A machine comprises an intermittently rotatable disc 1 having an odd number of mandrels 2 mounted concentrically, and means for intermittently rotating the disc so that at each movement it moves through an angle equal to twice the angular pitch of the mandrels so that the disc moves through at least two revolutions before a mandrel stops again at a given position. The machine may be used to make open packets, with or without a lining, or complete the filling of the packets, as by cigarettes. The disc 1 having twenty-five mandrels 2 projecting at right angles to its face is rotated by any kind of intermittent motion, such as a Geneva movement. Bare mandrels are shown in full lines, those shown dotted containing packets. A blank 4 is inserted at the feeding station BFS, receiving lines of adhesive, passes to the first folding station FFS where the blank is folded into a tube using guides 20 of known type. Folding blades 8, 9, move to and fro across the upper face of the mandrel. The tube seam 11 is pressed on by a gripper 10, which may be heated. At the next stop, the second folding station SFS, the narrow sides of the tube are tucked over the mandrel end by tuckers 12, the two broad flaps being then folded down on top by folders 14, 15. The folded end of the tube is pressed on at the first pressing station FPS by a plunger designed to give high localised pressure to the adhesive-covered flaps. This is described in Specification 617,462 and comprises a plunger, actuated by a crank, which moves down the hollow mandrel. A similar operation occurs at the second pressing station SPS and the packet is then carried around by the disc for more than one complete revolution while the adhesive is drying. The packet, in this case to be filled, then reaches a filling station FS where cigarettes are inserted and a device used such as is described in Specification 614,860. The packet is delivered at the ejecting station ES. Where a foil lining is required, a sheet of foil 28 is fed in at station TFS and passes between guides 28 to the blank-feeding station BFS. Grippers 5, 10, may be actuated by any suitable mechanism ; as shown, they are moved by cams 35, 36. One mechanism to move the disc intermittently comprises twenty-five studs 32, Fig. 5, which are engaged by a single thread worm 33 which engages with every second stud and moves the disc through an angle equal to twice the pitch angle of the studs at each movement. The worm has a part 34 of zero lead and while this part is passing between the studs, the disc is stationary.

Title: Process for the preparation of 4-(p-aminobenzenesulphonamido) pyrimidines
IPC: C07D239/69
Filed: 1953-11-27
Abstract: In a process for the production of 4-(p-aminobenzenesulphonamido) pyrimidines, wherein a benzene sulphonyl halide having a substituent convertible to an amino group in the p-position is reacted with a 4-aminopyrimidine and the substituent in the para position is then converted to an amino group, the condensation of the benzene sulphonyl halide with the 4-amino-pyrimidine is carried out in the presence of an amine of the general formula (CH3)2N.R, in which R is an alkyl group of 2-4 carbon atoms, as an acid-binding agent.  Any bis-(benzenesulphonyl)-aminopyrimidine formed in the condensation is converted to the required 4-(p-aminobenzenesulphonamido) pyrimidine by splitting off a benzene sulphonyl radical by hydrolysis, before, during or after the conversion of the para substituent to an amino group.  The specified acid-binding agents include dimethyl-ethylamine, -propylamine and -butylamine.  In an example 4-amino-2 : 6-dimethyl-pyrimidine and acetylsulphanilic acid chloride are heated with ethyldimethylamine in methylene dichloride, and the product is hydrolysed to give p-aminobenzenesulphonyl-4-amino - 2 : 6 - dimethylpyrimidine.  Specification 673,280 is referred to.

Patent GB-1031075-A (GB)
Title: Novel acetylenic compounds and a process for the manufacture and conversion thereof
IPC: C07C45/67
Filed: 1963-08-21
Abstract: The invention comprises acetylenic compounds of the general formula <FORM:1031075/C2/1> in which R1 and R2 each represent a hydrogen atom or the acyl residue of a carboxylic acid, and also 3,7-dimethylocten-(1)-diol-3,7.  The novel acetylamic compounds are produced by treating the compound <FORM:1031075/C2/2> with an aqueous mineral acid and, if desired, converting the product into a carboxylic diester.  The preferred mineral acid is sulphuric acid but other acids, e.g. phosphonic, nitric or a hydrohalic acid may be used.  The compound in which both R1 and R2 represent hydrogen may be converted to 3,7-dimethyl-7-hydroxyoctanal-(1) (hydroxy-citronellal) as follows: (a) it is partially hydrogenated in the presence of a hydrogenation catalyst to produce 3,7-dimethylocten-(1)-diol, 3,7; this diol is then oxidized to 3,7-dimethyl-7-hydroxy-octen-(2)-al-(1) either directly, e.g. by chromic acid or in two stages by first treating the dol with a halogenating agent to give 1-halo-3,7-dimethyl-7-hydroxy-octene-(2) and oxidizing this with nitromic acid; the a ,b -unsaturated hydroxyaldehyde is then hydrogenated, e.g. using palladium on charcoal as catalyst, to give hydroxy-citronellal.  An acetylenic diester is converted to hydroxy-citronellal as follows: (a) it is first converted to the corresponding 3,7 - dimethyl - 7 - acyloxy - octen - (2) - al-(1) by re-arranging it, in the presence of a rearrangement catalyst (e.g. silver carbonate, silver acetate, silver trifluoroacetate, silver nitrate, silver fluoroborate, silver perchlorate, copper powder or copper acetate), to the allenic diester 3,7-dimethyl-1,7-diacyloxy-octadiene-(1,2) which is partially saponified; (b) the a ,b -unsaturated monoacyloxy-aldehyde so obtained is catalytically hydrogenated, e.g. in methanoline solution using a palladium on charcoal catalyst to give a mixture of a 3,7-dimethyl - 7 - acyloxy - octanal - (1) and its dimethyl acetal; and (c) completing the acetal conversion and hydrolysing the product first in alkaline medium to give 1,1-dimethoxy-3,7-dimethyl-7-hydroxy-octane and then in acidic medium to give hydroxy-citronellal.

Title: Improvements in or relating to the production of synthetic fibres from polymers and copolymers of acrylonitrile
IPC: D01D5/06
Filed: 1949-12-28
Abstract: <PICT:0695448/IV (a)/1> <PICT:0695448/IV (a)/2> The process of the parent specification is modified in that the stretched polyacrylonitrile filaments are treated with a liquid composition containing an antistatic agent, then dried while travelling under tension in a helical path, and then passed in a continuous manner, while relaxed and free to contract linearly, through a heated zone maintained at a temperature within the range of 100-500 DEG  C. at a rate such that the time of exposure of any point of the filaments is within the range of 0.01-5.0 seconds. The treated filaments have little or no residual shrinkage, and they have improved extensibility, rendering them suitable for weaving, knitting, and other textile operations.  As shown in Fig. 1, polyacrylonitrile filaments are obtained by extruding a solution of the polymer through a heated spinning head and nozzle 14 into a cooled aqueous coagulating liquid 22 in the bath 24. The coagulating liquid may be water and it may be maintained at a temperature below 10 DEG  C. by continuous circulation and cooling, or by adding ice or a freezing mixture to the water in the bath.  The filaments are given an extended travel in the bath by passing them to and from submerged rollers 34, 36.  The filaments pass from the bath to a stretching device.  They are stretched by passing round roller 38, then in a straight line through a trough 42 containing hot water and then round roller 44 which has a greater peripheral speed than roller 38.  They are collected on a bobbin 50.  The wound bobbin 50 is placed in a trough 64, Fig. 2, containing an anti-static finishing composition, and filaments from the bobbin pass in helical turns round a pair of mutually inclined drying cylinders 70, 72.  The dried filaments pass through a heating zone provided by a groove in a metal block 82, which is heated electrically, and thence to a godet 76, which has a lower peripheral speed than rollers 70, 72, so as to allow the filaments to contract during the heat treatment.  Slippage of the filaments over godet 76 is prevented by means of the weighted pinch-roll 92. The filaments pass under tension from godet 76 to a ring-twister 86.  If desired, the filaments may be passed continuously from the stretching device to the devices for applying the anti-static composition, to the drying, heat-treatment, and relaxing devices, and finally to a winding and twisting device.  The apparatus described in Specification 695,536 may be used. Specifications 594,999, 672,775, 689,742 and 689,744 also are referred to.
