Filed: 1929-09-11
Abstract: 332,124. McNeil, P. E. Oct. 1, 1928, [Convention date]. Screw propellers; propeller shafts, arrangement of; propeller guards.-Two screw propellers are arranged coaxially so that the second propeller is rotated in the same direction as by utilizing the rotational or angular component of the pressure exerted by the blades of the primary screw element, and produces a thrust supplementary to that produced directly by the primary screw element. The screw propeller e is keyed on a shaft, and is of greater pitch and smaller diameter than a normal propeller designed for working under the same conditions. Arranged to rotate freely upon the extended boss i of propeller e is another propeller f of large diameter. The propeller f is designed, up to a radius approximately equal to that of propeller e, on a rotor principle and is rotated as described by the propeller c, the stream being directed aft after leaving the rotor blades. The remaining portions of the blades of propeller f are designed as driving propeller blades and the thrust is transmitted to the propeller shaft through the thrust bearing o. In a modification the propeller e is mounted on a hollow shaft and the propeller f upon an internal solid shaft, the thrust bearing being arranged within the ship.

Title: Improvements in the manufacture of acetyl cellulose
IPC: C08B3/06
Filed: 1937-10-12
Abstract: Concentrated solutions of stable, partially saponified cellulose acetates of high viscosity are prepared by commencing acetylation of cellulose by means of acetic anhydride at low temperature in the presence of a small quantity of acetic acid or other solvent and concentrated sulphuric acid, continuing at a similar temperature in the presence of an acid sulphate, completing at a raised temperature after addition of an acid such as nitric, phosphoric, or hydrochloric acid, or acetyl chloride and subjecting the triacetate at a raised temperature to the usual partial saponification by means of water, there being added for stabilizing the product a salt which reacts with sulphuric acid to form a sulphate which is insoluble in concentrated acetic acid but soluble in water or dilute acetic acid. In an example, cellulose is added to a small quantity of acetic acid and 0,5 per cent of its weight of sulphuric acid.  The second stage of the reaction is carried out at 25-30 DEG  C. with the addition of sodium bisulphate, and the third stage at 40 DEG  C. after addition of nitric acid. Partial saponification and stabilization are conducted by heating with aqueous acetic acid and magnesium acetate. In a second example, the second stage of the acetylation is carried out in the presence of ammonium bisulphate, and the acetylation is completed after adding phosphoric acid.  Saponification and stabilization proceed as in the first example.  In a further example, acetylation is commenced in the presence of a small amount of sulphuric acid, the second stage is carried out in the presence of zinc bisulphate, and acetylation completed after adding acetyl chloride.  The saponification and stabilization are effected by heating with aqueous acetic acid containing sodium acetate.  In another example, magnesium bisulphate is added in the second stage and gaseous hydrogen chloride is introduced during the third stage.

Patent GB-464050-A (GB)
Title: Improvements in the manufacture of artificial filaments, yarns, ribbons and like materials
IPC: D01F2/28
Filed: 1935-10-11
Abstract: The extensibility of artificial filaments, threads, yarns, and like materials having a basis of an organic derivative of cellulose is improved by treating them with a medium comprising a latent solvent dissolved in an inert diluent and having a small shrinking power, and then increasing the concentration of the latent solvent on the materials by removing at least part of the diluent, these operations being effected in the absence of tension sufficient to stretch the materials.  Shrinkage may be allowed to take place.  The diluent may be removed by preferential evaporation if it is more volatile than the latent solvent, or the materials carrying the relatively dilute solution of latent solvent may be treated with a bath which is a solvent for the diluent.  Methylene and ethylene dichlorides may be used as latent solvents.  As diluents, amylene, pentane, isopentane, tetramethyl methane, ethyl chloride, isopropyl chloride, diethyl ether, and methyl ethyl ether, may be used.  Treatment may occur at low temperature if desired.  The materials may be treated in hank, bobbin, or other package form, or while travelling, e.g. from dry or wet spinning apparatus to winding or twisting devices, or while in parallel formation.  The process may be applied to materials which have been stretched.  In an example, cellulose acetate yarns are led in warp formation through a bath of methylene chloride in ethyl chloride at 8 DEG  C.  The issuing yarns are led through a warm chamber in which the concentration of methylene chloride on the materials is increased by evaporation of ethyl chloride, and the materials are allowed to shrink.  They are subsequently washed. Benzene or other hydrocarbon may be used as washing liquid.  In another example, bobbins of loosely wound cellulose acetate yarn are immersed in a solution of methylene chloride in methyl ethyl ether. Warm air is blown through the bobbins to increase the concentration of the methylene chloride.  The bobbins are washed with benzene. Materials of other cellulose esters or ethers may be similarly treated.  Specification 389,823 is referred to.

Title: Improvements in or relating to machines for cutting teeth and grooves
IPC: B23F1/04
Filed: 1921-10-24
Abstract: 170,599. Schaerer, O. Oct. 22, 1920, [Convention date]. Gear-cutting; broaching; tools.-In a machine for cutting grooves and particularly for roughing cut the teeth of straight or helical spur gears, all the teeth are cut simultaneously by a number of tools radially arranged in a tool head and fed towards the blank at each working stroke until the full tooth depth is attained, whereupon the tool-head is automatically opened and the machine stopped. The blank is carried on a mandrel 6 on a shaft 5 sliding in a bush 4 provided with an oil tray and a threaded spindle 21, angularly adjustable from a short shaft 24, is carried in a bearing on a vertical slide 18. The driving pulley 10 when coupled to a friction member 9 by the displacement of a collar 11 drives a shaft 12 carrying a cam 14 operating the vertical slide and also a cam 16 actuating a lever 28 pivoted on a shaft 25. A slide 33, Fig. 9, is provided with' a short shaft carrying a ratchet wheel 43 and cam 42 actuating a spring-pressed sliding member 57 connected by levers 62, 63 to the tool-head 2. The latter comprises a series of radially arranged tools 70 secured by teeth 72, groove and spring 71, and screw 73 to holders 69, each of which has a pin 74 engaging a curved slot in a ring 68 which is rotated to feed the tools. Alternatively, the tool-holders may be pivotally mounted as shown in Fig. 7. For producing internal teeth, the cutters and the curved slots in the ring 68 are oppositely arranged. In operation the blank is vertically reciprocated by the quick-return cam 14, and at the end of the cutting stroke the cam 16 lifts the lever 28, which through further lever mechanism 39, 37 operates the slide 33 to shift the lever 63 and open the tool-head. At the end of the return of the blank the lever 28 is released by its cam and the slide 33 is returned by a spring against a stop 41, while simultaneously the ratchet 43 operates the slide 57 to impart cutting feed to the tools. When the required tooth depth is attained the cam 42 releases the slide 57, which is returned by a spring to open the tool-head, and simultaneously a pin 51 coacts with a latch 49 to release a spring- pressed bar 52 to disengage the friction clutch 9 and stop the machine. For cutting straight teeth the blank is held against rotation by an arm sliding in a guide 65 on the frame, while for helical teeth a toothed segment secured to thespindle 5 engages a rack on the frame having teeth at the required angle so that a combined axial and rotary movement is imparted to theblank.
