Title: Process and apparatus for dry spinning and for reducing the lustre of artificial silk
IPC: D01F2/30
Filed: 1930-10-01
Abstract: <PICT:0359385/IV/1> <PICT:0359385/IV/2> Artificial silk of reduced lustre is obtained by extruding a solution of a cellulose ester such as the acetate in a volatile solvent into a spinning cell in which a current of air or gas is set up by mechanical means located inside the spinning cell and directed in the vicinity of the spinning nozzle at right-angles or obliquely to the issuing filaments so that the latter are exposed to unequal lateral pressures.  The disturbances in the evaporation of the solvent result in solidified filaments the outer surfaces of which display two or more re-entrant surfaces. Such filaments are less lustrous than those with a dumbbell shaped cross section which are produced when evaporation of solvent proceeds uniformly.  As shown in Fig. 1, a spinning chamber a is heated by air or other medium circulated through a jacket b and is traversed by a current of air or other gas entering at c and issuing at d.  A fan h, located laterally of the spinning nozzle f within the spinning cell sets up a current of air at right-angles or obliquely to the filaments issuing from the nozzle.  As shown in Fig. 8, the filaments obtained have outer surfaces with two or more re-entrant surfaces. They have a lustre similar to that of natural silk.

Waste heat, utilizing.-The cooled waste combustion gases from a carbonizing plant are passed to a drying apparatus for the coal &c. before it is charged into the retorts. Coal from a crusher a passes through a drier b to the coke ovens d. A steam boiler f, provided with short flues, is heated by burning the semi-coke and distillation gases produced in the ovens d and it supplies steam to a turbo-dynamo k while the combustion products, reduced in temperature, are passed to the coke-oven d and thence travel to a steam superheater i, feed-heater l, the drier b, and stack c. Exhaust steam from the turbine also heats the drier, passing into a chamber which may be kept under vacuum, and condensate is pumped to the feed-heater l. In a modification, part of the distillation gases of coke ovens is utilized in a gas engine, part is burnt in the drier, and another part burnt in the oven. To increase the temperature of the waste gases if too low for use in the drier, they may be mixed with products of combustion coming direct from burners supplied with gas from the retorts. In the Specification as open to inspection under Sect. 91 (3) (a), any hot gases, the temperature of which exceeds that desired for processes in which they are to be used, are reduced in temperature to the desired degree by utilization in any useful apparatus. This subject-matter does not appear in the Specification as accepted.

[Class 103 (i)] A device 9 for the adjustment of the shoe clearance in a hydraulically operated brake is pivoted at one end on a bracket 20 and at the other end to a bracket 23 secured to the shoe, and comprises a cylinder 17 within which is a spring-loaded resilient plug 15 having passing through it a rod 11 with an enlarged head 12 at one end, and which is screwed into an eye 10 at the other end and connected by a pin 8 to the bracket 23. When the shoes 4, 4<SP>1</SP> are moved into engagement with the drum 3, the normal clearance 2 is permitted without movement of the plug 15 by its distortion in combination with the play in the connection 22, 23. If due to shoe lining wear the normal clearance is exceeded, the force exerted on the shoes by the actuator 7 is sufficient to move the plug 15 relatively to the cylinder 17. When, however, the brakes are released, the force of the retraction spring 6 is insufficient to move back the plug 15 so that the shoes are re-set at their original clearance. In a modification the plug 15 has a conical central aperture and the rod has a correspondingly conical external surface, the compression spring being located inwardly of the plug.
