Title: Improvements in machines for making tubes by helical winding
IPC: D05B13/00
Filed: 1948-09-14
Abstract: 697,001. Making fabric tubes. SPIRAL BAGGING MACHINE CORPORATION. Sept. 14, 1948 [Oct. 2, 1947]. No. 24134/48. Class 99 (ii). In a machine for making fabric tubes in which a sheet of material is wound helically on a stationary mandrel A, the helical seams being stitched at a sewing point 14, and the mandrel comprises parallel fixed bars 10, 11 and one or more movable rods 36, at least one of which is on the side of the machine opposite the feed table 13, for small adjustments of the size of tube, larger adjustments are made by the provision of one or more detachably mounted rods 37. The rods 36 are supported by links 29, Fig. 3, connected to the frame 28 and links 30 connected to a bar 31 actuated by the handle 35 of a screwed spindle 32. The rods 37 are carried by arms 38 detachably secured to the bar 10, the length of the arms used being selected to suit the size of tube required. The tube is flattened on leaving the mandrel by a spreading device comprising adjustable links 15, 18, and stored on a winding device C. Since the axis of the mandrel may vary in position according to which rods 36, 37 are used, the winder is laterally adjustable on rails 27, and the spreader may be secured in selected positions on a cross-bar 25. Specification 571,397, [Group VII], is referred to.

Abstract: 261,882. Waldowski, E. Oct. 1, 1925. Cigarettes and cheroots ; tobacco.- A continuous strip of material for the wrappers of cigarettes, cigarillos, and the like is made by cutting tobacco leaves into strips, pressing them to give a paper-like character, and joining them by means of adhesive preferably contained in a moistening bath through which the leaves are passed. In the apparatus shown, the cut-up leaves are placed at d on an endless belt b and are carried between the belts a, b through baths h, i of liquid, which may contain an adhesive. On leaving the belts a, b, they pass between belts l, v and pressing rollers p - - u and over heated rollers u, n, and the resulting web is wound on a spindle z. The belts i, v are of metal, the belt v passing between fluted rollers w and the resulting corrugations being pressed out by the rollers p, q, this operation exerting a stretching action on the fibres of the leaves. The corrugations may be transverse, longitudinal, crossed, or zig-zag, and the band l may be similarly corrugated when thick leaves are employed.

Title: Preparation of carbon black
IPC: C09C1/54
Filed: 1958-07-30
Abstract: Carbon black is produced by reacting one or more hydrocarbons with carbon dioxide at a temperature of 900-1200 DEG C. for a period of 0.001-0.20 sec., preferably 0.001-0.1 sec., and then cooling the reaction mixture to below 800 DEG C. within a period of 0.001-0.01 sec.  The hydrocarbon reactant may be natural gas or a residual gas from a FischerTropsch or methanol synthesis, or a mineral oil refining plant.  The reactants may be heated before and/or after mixing.  A nickel or cobalt catalyst may be present to produce a gaseous product containing methane ethane, and ethylene.  All or a portion of the gaseous reaction product may be recycled, converted to carbon dioxide and then recycled, or burnt to heat the reactants before and/or after mixing.  Unreacted hydrocarbon gas may be added to the product gas to raise its heating power.

Patent GB-1291668-A (GB)
Title: Web feeding device
IPC: G03B1/56
Filed: 1971-04-19
Abstract: 1291668 Film threading; optical projection apparatus RICOH K K 19 April 1971 [8 April 1970] 24638/71 Headings G2A and G2E [Also in Division G5] A film feed device (also applicable to other web handling apparatus e.g. magnetic tape equipment) includes devices for driving both a reel and the film stored thereon so as to strip off the film and direct it to further film handling apparatus. As shown a microfilm reader accepting strip film 4 has a supply reel 13 housed in cartridge 12 having an aperture 12f. The film stripping device includes an arm 18 pivotable about shaft 25 and carries rollers 15, 16 for engaging the rim 13a of the reel 13 and the film 4 on the reel 13 respectively. When the shaft 25 is rotated anticlockwise (as viewed in Fig. 1) the spring 31 Fig. 3 urges friction disc 28 to grip pulley 24 mounted on the shaft 25 and the arm 18 pivots into the cartridge 12 through aperture 12f and until the rollers 15, 16 contact the reel and film respectively. The pulley 24 then rotates relative to the disc 28 and drives the rollers 15, 16 through belt 23. The different diameters of the rollers 15, 16 gives the film 4 a higher circumferential velocity and so strips it from the reel 13 and supplies it to capstan roller 5 and pinch roller 6, idler roller 10 and to take up reel 41 in casing 42. The film 4 on entering the casing 42 is prevented from being wound on to the reel 41 in the wrong direction by the surface 45a of arm 45 and the film 4 is directed around the reel 41 until passed between the wheel 44 on the arm 45 and the hub 41a. The sequence of operations is controlled by the switches S M , S 1 , S 2  which when closed power a clutch MC and transmit the drive of motor M to the shaft 25. To start the switch S M  is closed, S 1  and S 2  being already closed and the shaft 25 powered. When the film passes between the rollers 5, 6, the latter is forced downwards and so rocks the arm 39 and permits the switch S 1  to spring open. The film stripping device therefore stops and is retracted under the action of spring 35. As the amount of film on the reel increases switch S 2  is permitted to open because the arm 47 is connected to the arm 45 via shaft 46. The film advance is terminated by providing a slot in the film 4 near its end so that the pinch roller 6 can pass therethrough and contact the capstan roller 5 so preventing undesired tensions being placed on a film end attached to the supply reel 13. The optical system of the projection includes a film gate 7, 8, lens 9 and a light source (not shown) on the opposite side of the gate 7, 8. The projection path may include a reflector.
