Patent GB-388848-A (GB)
Abstract: 388,848. Calculating-apparatus. MARCHANT CALCULATING MACHINE CO., Oakland, California, U.S.A.-(Assignees of Talamini, L. ; 375c, Hawthorne Avenue, Oakland, California, U.S.A.) Oct. 12, 1931, No. 28328. Convention date, Oct. 13, 1930. [Class 106 (i).] Transfer - mechanism.-In calculating-machines having successively acting rotary transfer actuating members the peripheral displacement of the successive orders is diminished so as to increase the capacity of the machine. For this purpose the laterally movable transfer tooth is so shaped that the gear-operating phase begins before the completion of the positioning phase. As shown applied to machines with reversible rotary actuators as described in Specifications 305,540 and 318,256, [both in [Class 106 (i), Calculating &c.], the transfer actuating members 12, Figs. 1 and 2, are arranged in pairs on the rotary actuators in two converging spirals. Each numeral wheel of the totalizer carries a cam 9 which at transfer effects the setting of a transfer lever 10 so as to position its cam surface 11 into the path of the member or tooth 12 of the next higher denomination. The projecting part of each tooth 12 is formed with a bevelled surface 15, Fig. 4, to co-operate with a complementary cam face 17, Fig. 7, of the cam lever 10 permitting a closer peripheral spacing of the teeth 12. Specifications 13700/90, [Class 106, Registering &c.], and 185,852, [Class 106 (i), Calculating &c.], are referred to.

Abstract: 1,243,650. Knitted fabrics. KARL MEYER TEXTIL MASCHINENFABRIK G.m.b.H. 14 Aug., 1968 [17 Aug., 1967], No. 38922/68. Heading D1K. Warp knit pile fabric is produced by forming the pile yarn into loops on empty needles and passing it across one or more wales of the ground fabric between loops and engaging the pile yarn in the yarn extending between the wales. The fabric may be a three-bar fabric comprising on bars 3 and 1 a 1-0/0-1 chain and a 1-0/2-3 chain respectively while the pile yarn on bar 2 makes loops on empty needles, e.g. 5, 6 and between loops crosses wale 7. In a four-bar fabric comprising a 1-0/0-1 chain and 1-0/2-3 and 2-3/1-0 chains the pile yarn again makes loops on empty needles and crosses a wale in between. In other examples the pile yarn may be incorporated in a ground fabric comprising chains and laid in wefts or may cross two wales forming loops on either side of and between the wales.

Solenoid (6) is again actuated and support (25) is retracted, the first screw drops to the position of Fig. 3 (not shown), where it rests on the bottom (80) of slide (12). The second screw slides down the shoot and rests against the side of slide (12), and as the latter moves downwardly, Fig. 1 (not shown), the first screw drops from the bottom (80) into delivery tube (4), and is impelled by air escaping through a passage (29), into an adapter (5) fixed to screw driver (2). Screw driver (2) comprises a housing (43) containing an air turbine which drives a shank and bit (44), (45), Figs. 13, 14 and 15 (not shown), through a clutch engageable by work pressure against bit (45). Adapter (5) comprises a barrel (49) which is slidable on body( 46) of the driver, against a spring (54), a member (58) pivoted at (59) for gating the screws, and screw engaging jaws (62), Fig. 3 (not shown). A switch (66), Fig. 13, is used for manual control of the screw driver, and switches (67), Fig. 27, and (75), Fig. 33 (not shown), controlled by the sliding movement of adapter (5) and by pivoting movement of jaws (62) respectively are provided for automatic control.

Title: Improvements in or relating to tobacco web material
IPC: A24B15/12
Filed: 1959-11-20
Abstract: After the extraction of water-soluble constituents therefrom, natural tobacco is chemically digested to form a fibrous pulp from which a web is made, the web being thereafter impregnated with at least a portion of the extract.  The extraction is effected by hot water in a closed tank, followed by draining, pressing and/or centrifuging.  If the extract or insoluble portion are not to be immediately further treated they may be refrigerated or the latter formed into a dry pulp lap. Chemical digestion of the insoluble portion is effected by a caustic under pressure or by nitric acid, the digestion liquor being then removed by draining and pressing.  Caustic digestion is controlled to leave the resultant pulp neutral, but nitric acid digestion leaves an acid pulp which is waterrinsed, neutralized with sodium hydroxide or carbonate, and again rinsed.  The pulp is then formed into a water slurry and refined in a paper-making beater having a roll which effects a brushing action, fillers such as titanium dioxide, clay, calcium carbonate or activated alumina being added, after which the slurry is further refined in a Jordan machine, disc refiner or both, and is made into a web on a Foudrinier machine or other paper-making machine such as that of U.S.A. Specification 2,045,095, to the headbox of which an aqueous solution of cationic starch is fed simultaneously with the slurry, which may also have added thereto in the headbox a minor proportion of a slurry of manila hemp fibres of 5 ... 8 mm. fibre length.  The formed and dried web is saturated by spraying or bathing with a solution of aldehyde and a protein or polymeric alcohol cross-linking agent and, optionally, humectant, ethyl or isopropyl alcohol and phosphoric acid, and is again dried.  The polymeric alcohol may be polyvinyl alcohol and the protein may be soybean protein, casein or gelatin, and the aldehyde may be formaldehyde, acetaldehyde or glyoxal.  Some or all of the aqueous component of the solution may be neutralized extract as described below.  The water-soluble constituent extract is concentrated by evaporation and then acidified by a mixture of phosphoric and citric acids, the resulting protein precipitate being separated off if desired.  The extract is then neutralized by potassium carbonate, and humectant, vegetable dye and, optionally, polyvinyl alcohol are added.  The humectant may be glycerol, sorbitol or propylene glycol.  The extract is added to the web by spraying or bathing, and the web is then dried and impregnated by running it through an emulsion of water and a vegetable wax or polyvinyl alcohol.  Finally, the web is calendered and/or embossed to simulate tobacco leaf.  The extract and insoluble portion may be bleached with hydrogen peroxide immediately after separation, even sufficiently to give a white final web for use as cigarette wrappers.  The final web may also be used for cigarette fillers and cigar wrappers and binders.  Quantitative process examples are given.
