Abstract: 539,476. Emulsions. JOHNSON, G. W., (I. G. Farbenindustrie Akt.-Ges.). July 16, 1938, No. 21141. [Class 1 (i)] Aqueous dispersions of highly polymeric organic water-insoluble substances are made by dispersing solutions of these substances in waterinsoluble solvents in water in the presence of an emulsifying agent and small quantities of a water-soluble organic solvent. Substances treated may be polyisobutylene, natural or synthetic rubber, polyvinyl compounds such as acrylic and methacrylic acid esters and polyvinyl ethers and also cellulose derivatives such as benzyl cellulose. Suitable water-insoluble solvents are chlorbenzene, carbon tetrachloride, carbon bisulhide, methylene chloride, cyclohexane, benzine, benzene, toluene or xylene. Suitable watersoluble solvents are monohydric or polyhydric alcohols such as methyl and ethyl alcohol. glycols and glycerine. low molecular ketones such as acetone and methyl ethyl ketone and cyclic ethers such as dioxane. Protective colloids such as glue, casein, polyacrylic acid sodium or ammonium salt, polyvinyl alcohol or water-soluble or urea formaldehyde condensation products or water-soluble cellulose derivatives may be added. Other substances which may be added are fillers, dyestuffs and other dispersions such as emulsions of asphalt or bitumen, or rubber latex. Mixtures containing the latter may be vulcanized. The preferred sequence of steps is to treat the substance with the water-insoluble solvent and then with water and an emulsifying agent, a dispersion of the water-in-oil type being obtained by mechanical working in a colloid mill. homogenizer or turbo-mixer. The resulting thin to viscous paste is then treated with the watersoluble solvent with resultant inversion and the production of mobile paste. Both solvents may be removed by distillation end the dispersion thickened either by vacuum distillation or by creaming. To prevent undue concentration of the emulsifying agent and protective colloid fresh solution of the highly polymeric substance may be added during distillation. The products may be used for coatings and impregnations for textiles, painting compositions, adhesives, binding compositions and solid non-tacky films and foils. Examples relate to emulsions of polyisobutylenes having molecular weights from 15,000 to 200,000. polyvinyl isobutyl ether, butadiene rubber and benzyl cellulose. The emulsifying agents used are sodium or ammonium oleate, and butylalphanapthalene sulphonic acid sodium salt.

Abstract: 320,681. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). July 21, 1928. Loose-nailing.-In a fastener-inserting machine, tack-holding jaws are mounted in a tack block upon obliquely arranged pivots, so that they lie at an angle both to the driver path and to the face of the work into which the tack is to be driven. As shown applied to a step-by step last ing machine of the kind described in Specification 14453/97, [Class 17, Boots &c.], the tack block 2 has formed in its side faces inclined grooves 8. In each groove is mounted a tack-holding jaw 14 which can swing upon a pivot pin 24 arranged in the tack block at right angles to the grooves 8. Each pivot pin has, near one end, a groove 26 with which engages a locking pin 30. The locking pin is retained in the tack block by a pair of leaf spring 32 secured to the sides of the block by screws 36 and pins 38. The forward ends of the springs are inturned to press together the two jaws 14. The latter at the meeting faces, are cut away to form a conical tack-receiving recess 22. By the arrangement described, the tackholding jaws may be a part of the wiping surface 42 of the tack block without risk of injury to them by the wiping pressure, since they are supported against that pressure by the upper part of the tack block, Further, the oblique arrangement of the pivot pins minimises the vertical and transverse movements of the jaws as they are swung apart when the driver descends. The jaws are readily removable by releasing the springs 32 and driving out the locking pin 30 and pivot pins 24.

A wound bobbin collecting and empty bobbin delivery device is mounted on guide rails for movement into a operative position with respect to one, or to one of a plurality of, crosswinding machines, the device having its own drive and control means for carrying out the necessary travelling and wound package exchange functions.  Fig. 3 shows a completed cheese 2, the cheese 2 being one of many carried by cross-winding machines on a rotary table 3. On completion of the cheese 2 an associated lamp 4 lights up to indicate that the cheese requires to be doffed. The mobile cheese exchanger 7, mounted on three wheels 5 of which one is stearable, is then moved manually or automatically to the appropriate table 3 to await the instant at which the winding machine with the fully wound cheese shall pass by. The winding machine to be doffed carries a further signal lamp 1 that illuminates on completion of a package and when this shines on a photoelectric cell 11 of the exchanger 7 a pulse is generated via a light 12 on the exchanger 7 to a photoelectric cell 13 on the table 3 to stop rotation thereof.  Doffing. Whilst the table 3 is at a standstill a cam 14 rotates to actuate levers carried by the exchanger 7 such that a tongue 17 moves forwardly and under the cheese 2 and then lifts it to a position where, after the arms 19 have been moved apart, the completed cheese rolls down the inclined tongue and to a trough 23. Donning. The exchanger 7 carries empty tubes 26 in a magazine 27, Fig. 5 (not shown) and before the arms 19 can revert to their lower and closed position a gripper arm 29, Fig. 6 (not shown) takes an empty tube 26 from the magazine 27 and deposits it between the ends of the arms 19. the arrangement being such that the thread 54 from the cop 24 passes over the empty tube 26 to the doffed package 2. To cause the thread 54 to wind onto the empty tube 26 a presser roller 33, Fig. 7 (not shown), swings downwardly to a position between the empty tube 26 and a grooved traverse member 18 to bring the thread 54 to said position and a motor 34 then drives the presser roller 33 to feed thread between the empty tube 26 and the grooved traverse member 18. As the thread commences to wind onto the empty tube 26 scissors 37, Fig. 8 (not shown) cut the thread between the doffed package 2 and the presser roller 33. Finally the trough 23 tips the package 2 via spring loaded flaps 42 (or an endless conveyor) into the cheese container 43. Further rotation of the cam 14 then causes roller 33 and tongue 17 to revert to their former position, the empty tube to rest on the winding member 18, rotation of the winding member 18 and a further light signal by the light 12, said signal acting on the photoelectric cell 13 to cause the table 3 to recommence its turning motion. The exchanger 7 then awaits a call to another winding station.
