Title: Improvements in or relating to tobacco-manipulating machines
Inventor: MOLINS DESMOND WALTER
IPC: A24C5/34
Filed: 1959-06-03
Abstract: 961,731. Cigarette-making machines. MOLINS MACHINE CO. Ltd. June 3, 1960 [June 3, 1959; Sept. 25, 1959], Nos. 19062/59 and 32648/59. Addition to 929,338. Heading A2C. Variations in air-permeability of a tobacco filler operate devices to adjust trimmer blades and/or the tobacco feed. The filler is formed by suction on a perforated band 2 and air is drawn through the filler before and after trimming by suction chambers 6, 102, the variations in pressure in which indicate the amount of tobacco in the filler. The chamber 6 is connected directly by a pipe 8 to a capsule 9 and chamber 102 is connected through a restriction 103a to a capsule 104, whereby capsules 9, 104, are responsive respectively to short-term and long-term variations in the filler resistance. The capsules are connected to a lever 101 which controls the position of the trimmer blades 5 through a servomotor 11 as described in the parent Specification. If the pressure in chamber 6 increases, indicating a smaller amount of tobacco in the filler, capsule 9 expands to move trimmers 5 away from the band 2 so that less tobacco is trimmed off. Capsule 104 acts similarly in response to long-term variations in the filler resistance. The pressure variations in pipe 103 are also transmitted to capsule 109 whereby long-term variations in the filler resistance control, through capsule 109 and servomotor 111, a valve 114 in the hydraulic drive of a motor 117 driving the shaft 118 of the feed means of a tobacco hopper. A reduction in resistance of the filler, as shown by a rise in pressure in pipe 103, results in an increase in speed of the feed shaft to supply more tobacco to passage 1 to increase the amount of tobacco in the filler. In a modification the pipe 108 is connected to the pipe 8 and contains its own restriction and in another embodiment the tobacco feed control is omitted.

Title: Improvements in or relating to paper sheet feeding mechanism
IPC: B65H29/00
Filed: 1937-07-09
Abstract: 498,236. Sheet-feed tables. POLLAK, J. E. (Brehmer, Geb.) July 9, 1937, Nos. 19129 and 32533. [Class 100 (i)] In paper sheet-feeding mechanism comprising a linear guide having freely rotatable friction elements, such as balls, rollers, or brushes, in individual contact with a series of power-driven revolving elements, for changing the direction of travel of the sheets, for example in a folding- machine, provision is made for relative adjustment of the contacting elements, in friction gear fashion, for controlling the feed of the sheets along the guide. In one form, the driven members consist of a series of flat discs 4, Fig. 5, rotated by gearing 11, 12 and carried by brackets 10 adjustable in a direction perpendicular to the guide 5. Balls 6 are employed as rotary friction members and are mounted freely in a holder 7 secured to and adjustable longitudinally of the guide 5 by a bolt-and-slot connection. The guide 5 itself is slidable for adjustment purposes in a part 17 of the bracket. To vary the speed of the sheets along the guide 5, the holder 7 is adjusted relatively to the guide, and to vary the pressure of the sheets against the guide, the guide is adjusted in the bracket part 17. The disc 4 may be replaced by shallow conical discs, the shafts of which are slightly inclined to the vertical so that the discs can overlap and provide a substantially unbroken support for the sheet edge. In another arrangement, Fig. 13,. the driven members 10 are segments of spheres and are carried by shafts 11 driven by gearing 13 ... 23. The guide and balls 5 are relatively fixed, and the members 11 ... 16 are mounted on a bracket 12 adjustable about the shaft 18 of the gear 17, which together with the parts 19 ... 22a are carried by another bracket 25 adjustable about the shaft 24 of the main driving gear. Variation of sheet speed and sheet pressure are obtained by adjustments of the respective brackets 12 and 25. The members 10 may be adjusted altogether, or individually where it is desirable to vary the speed of sheets fed in close succession to separate them. Truncated cones 31, Fig. 18, arranged with their operative edges in a horizontal plane may be employed as driven members, each with its driving gear being mounted in a bracket 38 adjustable about a vertical axis 34 to vary the sheet pressure against the guide 3. The speed of the sheet along the guide is varied by adjusting the balls 5 along the cones. The travel of the sheets up to the side guide may be assisted by air blasts blown upwardly through gaps in the feed-table.

Abstract: 184,036. Ruymbeke, J. van. July 15, 1921. Alcohol, dehydrating.-In preparing alcohol of 98-99 per cent strength, alcohol vapours are brought into contact with glycerine which acts as e dehydrating-agent. The glycerine preferably flows down a rectifying-column up which alcohol vapours are passed. In a continuous apparatus, alcohol of 92-93 per cent strength passes from a tank a through a preheater b to a column cheated by steam injected through a pipe n. The vapours from the top of the column are partially condensed in a condenser d, the liquid condensate from which is returned by a pipe r to the column c. The uncondensed vapours pass by a pipe q to the base of a column e down which glycerine admitted by a pipe s passes. The vapours pass from the top of the column to condensers f, g. Glycerine passes from the base of the column e to a column h in which it is treated with steam to remove alcohol which is passed as vapour bv a pipe x to the column c. The glycerine is finally treated to separate water and used again.

Abstract: 335,277. Ellis, G. B., (Soc. des Usines Chimiques Rh¶ne-Poulenc). June 25, 1929. Vitamines.- Substances having intense antirachitic effect are obtained by separating unconverted ergosterol from the product obtained by irradiation of ergosterol by means of crystallization from organic solvents in which ergosterol is slightly soluble, e.g. alcohol, acetone and methyl acetate, the separation being continued until the soluble residue in alcoholic solution shows a dextro rotatory power greater than 25 degrees for the yellow line of mercury. The acetic product is isolated by distillation of the solvent, or it may be taken up in a non-volatile liquid such as a vegetable oil. The irradiation is preferably carried out in solution in a hot organic liquid, e.g. ethyl alcohol at 75‹ C., and in an inert gas which may be used to agitate the solution by bubbling. When solid ergosterol is treated the anti-rachitic product may be extracted from the unconverted residue by an organic solvent. The irradiation is preferably effected with light having few or no rays below 2750 Angstroms, and is stopped preferably before the maximum production of anti-rachitic vitamin has been reached.
