Title: Conjugate artificial monofilaments
IPC: D01F1/10
Filed: 1960-09-21
Abstract: 968,328. Ion-exchange resin-containing artificial monofilaments. FMC CORPORATION. Sept. 21, 1960 [Oct. 30, 1959], No. 32464/60. Drawings to Specification. Heading B5B. Conjugate artificial monofilaments comprising at least two components, one component being exposed and having a major proportion of a finely divided ion-exchange resin intimately distributed throughout the cross-section thereof are made by extruding through a common orifice into a setting atmosphere or into a coagulating bath two melts or two spinning solutions, e.g. viscose, one of which contains an ionexchange resin dispersed in it and the other of which is resin free in side-by-side relationship or sheath-core relationship. The extruded products are passed through the setting atmosphere or the coagulating bath in parallel and joined at their peripheries along their entire length by intermingled portions of the products to convert them into a single conjugate monofilament having a portion of the resin-containing component exposed along the full length of the monofilament. The monofilament is then withdrawn from the setting atmosphere or coagulating bath and collected. The monofilament produced may contain over 40% by weight of the ion-exchange resin based on the total weight of monofilament. The resin-containing component may be extruded annularly around the resin-free component. The two filament-forming materials being extruded may be two viscoses, one containing the ion-exchange resin dispersed in it and the other being resin free. Both viscoses are extruded into a cellulose regenerating bath to form a conjugate monofilament in which one component is regenerated cellulose having the resin uniformly dispersed in it and the other component is resin-free regenerated cellulose. The resin-free component of the conjugate artificial monofilament serves as a structural reinforcement for the resin-containing component. When using cation-type ion-exchange resins in conjunction with viscose, the resins are converted into the sodium form before being incorporated in the viscose. When using aniontype ion-exchange resins they are converted into the hydroxyl form before being incorporated in viscose. Specification 579,081 is referred to.

Title: Process and apparatus for treating materials in grains, such as minerals, coals and the like, containing particles of comparatively small sizes
IPC: B03B5/68
Filed: 1937-11-26
Abstract: 494,998. Washing granular materials. HOYOIS, L. Nov. 26, 1937, No. 32667. [Class 82 (ii)] In treating a mass of granular materials such as coals, minerals, &c. containing particles of comparatively small sizes, the mass is carried along a trough or the like adapted to form a fixed bed of the materials with a movable bed running over the fixed bed, and when the movable bed is graded the lower portion only thereof is caused to pass into the fixed bed, e.g. by removing a portion of the fixed bed, in order to eliminate fine dense particles from the movable bed. The remaining grades of the movable bed may then be classified, e.g. by mechanical division or upward currents. In the form shown the materials fed at 1 into the trough A are carried by water from an inlet 7 along the bottom 9 of the washing compartment 2, which is bounded by a weir 22 so that a fixed bed of materials surmounted by a movable bed is formed. At a point where grading of the movable bed has been effected an adjustable opening 10 is formed in the bottom 9, the position and size of the opening being controlled by slides 28, 29. Material passing through the opening falls into a compartment 4 and is carried by a flow of liquid from 13 into a compartment 3 and ultimately to an adjustable discharge 18. As a result of the falling in of the fixed bed the lower layer of the movable bed sinks into the fixed bed and the material passing over the weir is free from fine dense particles. This material is classified by means of a dividing plane 24 with an adjustable slide 25, the heavier material passing into a compartment 5 formed by adjustable partitions 20, 23, where it is further classified by an upward current from the liquid inlet 16. The lighter particles raised by the upward current are collected together with those passing over the dividing plane 24, and the particles sinking through the current together with or separately from those passing through the opening 10. Two or more of the apparatus may be used in series. Specification 456,895 is referred to.
