Title: An improved apparatus for washing and after-treating artificial silk spun in the form of spun cakes
IPC: D01D10/04
Filed: 1931-04-07
Abstract: <PICT:0363257/IV/1> <PICT:0363257/IV/2> <PICT:0363257/IV/3> For washing and after-treating artificial silk cakes, a perforated tube divided longitudinally is provided and the cakes, preferably wrapped up in permeable wide-meshed fabric, are laid beside one another in the tube in a longitudinal direction.  The external diameter of the tube is adapted to the external diameter of the cakes.  Since the cakes are usually conical in shape, the tube may have internal conical gradations.  Ring-shaped discs inserted into grooves in the exterior perforated tube, may be provided for separating the cakes, or the discs may have distance-pieces which pass through the central openings of the cakes and so maintain the distances between the separating discs.  The height of the distance-pieces is such that no undesirable compression of the cakes may occur.  It may be slightly greater than that of the cakes so as to permit a limited degree of longitudinal swelling. When the tube has been filled with cakes, the two halves are locked together and liquid may be supplied at both ends, or only at one end, the other end being sealed by a closure plate.  In the drawings, a perforated tube consists of two halves 1, 2 which are hinged together and may be locked together by screw bolts.  The interior surface of the tube is constructed conically at intervals to conform to the shape of the cakes 7.  In Fig. 3, disc members 8 are situated between adjacent cakes.  The discs 8 are made integral with perforated distance-pieces 9 which project into the cakes.  In Fig. 4, the disc members 10 are held in p  grooves 11 in the wall of the tube, and distance-pieces are dispensed with. Washing, desulphurizing, or bleaching liquid is supplied to the interior of the tube, and is forced transversely through the cakes. The cakes may be wrapped in knitted or other permeable net-like material or may be bound with threads or strips.  Specification 355,645 is referred to.

Filed: 1917-07-24
Abstract: 114,554. Hoffmann, R. E. July 24, 1917. Aspirating apparatus, ejector; ejector-condensers; strainers.-Relates to means for preventing churning or vortex action in the pressure chamber surrounding the jets of water-operated ejector condensers, and water-operated extracting ejectors, and consists in a diffuser of one or more perforated or slotted plates superimposed upon the water jets and ensuring a breaking-up of the supply water into stream lines before entering the nozzles. Splashing near the connexion of the water-extraction pump is thus prevented in the case of jet condensers, and in the case of ejectors the passage through the combining and delivery cones is improved, blockage by foreign material is prevented, and the apparatus starts without special admission of steam. The diffuser preferably has a spherical surface formed about the centre point of the meeting of the jets, the area of the holes &c. being not less than twice that of the inlet pipe whereby a velocity between the diffuser and the nozzles of about 3ft. per second is stated to be obtained. The chamber bounded by the diffuser and the water-supply casting provides for the collection of solid substances &c., and has connexions enabling pressure readings to be taken to ascertain when the diffuser requires cleaning. The perforated plates may also be of conical, cylindrical, or flat form, with perforations or slots of any form, including those adapted to produce the effects due to apertures of vena contracta, venturi, and similar forms. Fig. 1 shows a water-supply head for a multi-jet ejector condenser or annular nozzle apparatus, having a side inlet S and a perforated curved diffuser plate A, fitted to a nozzle-shaped outlet T, and held in position by a removable cover R. The combining and delivery members are in the form of an annular series of nozzles N in a lower casting C. An annular space B forms a pocket for solids unable to pass the perforations. In a slightly modified form, the diffuser plate is an integral part of the water-supply head, or there may be a diffuser plate over each nozzle N. In another construction, a diffuser plate A, Fig. 4, for a single water ejector-condenser has a centre of curvature coincident with the apex of the cone of the water nozzle N, and is dished and fitted to the tapered outlet of the water-inlet casting H.
