Title: Improved means of lubricating the spindle of doubling and twisting machines
IPC: D01H7/20
Filed: 1930-04-03
Abstract: 358,422. Lubricating spindle bearings. CANALS, F. C. and OLIVERAS DE LA RIVA, V., La Gleva, Barcelona, Spain. April 3, 1930, No. 10640. Convention date, Oct. 29, 1929. [Class 12 (ii).] Spinning spindles of the kind in which the spindle is mounted in a sleeve and is independent from the driving pulley, to which it is connected bv a friction cone coupling, are lubricated by the circulation of oil from a reservoir by a spiral groove on the spindle to the upper end of the bearing surfaces, between which the oil passes and drains back to the reservoir. Lubricant passes from the reservoir through holes in the member 33 and is raised by the spiral groove 34 on the spindle 2 to the cavity 35, whence it spreads over the bearing surface of the loose wharve 18 on its supporting member 27 and passes via grooves 36 to the annular groove 37 in which the wharve 18 rests, and then returns to the reservoir through holes 38.

Title: Method and apparatus for separating tobacco
IPC: A24B5/10
Filed: 1961-03-23
Abstract: 976,903. Treating tobacco. K. KORBER. March 23, 1961 [April 16, 1960; Oct. 31, 1960; Feb. 22, 1961], No. 10675/61. Heading A2C. [Also in Division B2] Tobacco is pneumatically fed through pipes 9, 3 to an inclined separating chamber 10 within a casing 2, and the air flow causes the lighter leaf product to rise and be drawn through a duct 15 leading to a pneumatic extractor pipe 18, whereas the heavier rib product falls to a duct 4 and an outlet 7 via an extractor device 5 driven by a motor 6. Screen-like apertures 23, 24 are located in a wall 12, and a screen 25 is provided as shown so that air currents are drawn through the apertures 23, 24 into a chamber 30, and then pass through the screen 25 to the extractor pipe 18. Leaf material is thus deflected to a more vertical position towards the wall 12 and the rib material is deflected to a more vertical position downwardly. A secondary air inlet 19 adjustable by a valve 20 is located in the wall 11, and a similar valve adjusted port is positioned in the wall 16. The suction air flow through the apertures 23, 24 is controlled by a valve 28 which, in the closed position, cuts off the screen 25 from beneath. Adjustable V-shaped guides 32, 36 control the direction of inflow of the product. In a modification the lower wall of the pipe 18 is additionally in the form of a screen, and air flow through it is controlled by a valve; the apertures 23, 24 have adjustable covers to vary the airflow therethrough. Instead of the screen 25 of Fig. 1, that part may be replaced by a pivoted adjustable blade controlling flow from the chamber 30. In the embodiment of Fig. 7 the wall 12 is replaced by ducts 53, 54 and 55 extending to the pipe 18 and controlled by pivoted valves 73, 75 and 77.

Patent GB-473975-A (GB)
Title: Improvements in the manufacture of cellulose derivatives
IPC: C08B11/12
Filed: 1936-04-22
Abstract: Cellulose materials are impregnated with an aqueous solution of a base in concentration 10 to 16 per cent, subjected to the action of reduced pressure to remove water and increase the ratio of base to water, and etherified with an oxyalkylating or carboxyalkylating agent.  Evaporation of water from the materials preferably takes place at moderate temperatures, e.g. 35--45 DEG  C., until the concentration of the base is 25--35 per cent.  Suitable bases are potassium and sodium hydroxides, tetramethyl ammonium hydroxide and trimethyl benzyl ammonium hydroxide.  Etherification takes place immediately after concentration of the base if high viscosity products are required, or ripening may be effected before etherification if products of lower viscosity are required. As etherifying agents, alkylene oxides, epichlorhydrin, ethylene glycol monochlorhydrin, glycerol monochlorhydrin, cyclohexene oxide, or halogenated fatty acids or their salts may be used.  The products may be used as thickeners for printing pastes or as sizes.  According to the Provisional Specification, the process may be applied to the manufacture of other cellulose ethers, e.g. methyl and ethyl celluloses.  Specification 463,317 is referred to.

Abstract: 331,296. White, E. A., and Reeves, H. C. April 15, 1929. Delivery of articles stored in piles.-In a machine for delivering towels or like pliable articles, the towel is engaged by means so as to be bent or folded back on itself before being discharged into a shoot. As shown in Fig. 1, claws b<1> on a drum b engage the lowermost towel folding it back on itself towards the back of the casing a and dropping it into a curved shoot a<3>. The claws may be dispensed with by roughening the periphery of the drum. In a modified construction the towels are pressed upwards and the uppermost one is engaged by the drum. Coin action, mechanical-connection, multiple coin.-The coin, inserted in the slot e<1>, falls into a gap c<6>, Fig. 5, in a disc. c<4> fixed to the drum shaft c. On rotating the handle c<2>, a pin or the disc c<5> moving in the race d<1> of the fixed disc d impinges on the edge of the coin and causes the drum shaft c to rotate. The gap c<6> may be made of such a depth that two or more coins are required before the machine can be operated. Coin-discharging mechanism.-On the drum b being rotated the required amount the coin is discharged from the gap c‹ through an opening in the disc d' by a spring finger carried on the back of the disc c<5>, into a receptacle e<2>. The drum now returns to its initial position under the action of the spring c<1>. Coin-slit closing devices.-A cranked rod g is normally kept adjacent the side of the casing a against the action of a spring by a loose plate h resting on the towels. On extracting the last towel the plate releases the rod which then turns and, through an eccentric pin attached to its lower end, causes a slide g<1> to close the coin slot e'. Testing coins.-The disc d is provided with an aperture d<3> opposite the gap c<6> in the disc c<4>, having a diameter slightly smaller than that of the appropriate coin.
