Title: Improvements in tube spinning of viscose and the like
IPC: D01D5/06
Filed: 1957-11-08
Abstract: In wet-spinning apparatus of the type in which viscose is extruded from a spinneret submerged in a spinning bath to form a bundle of filaments which travel from the spinneret to a thread guide through a straight tube open at both ends, the centre of the spinneret face, the axis of the tube and the point of first contact of the filament bundle with the thread guide being in alignment, the straight spinning tube has a longitudinal slit extending from end-to-end thereof, the axis of this tube being at an angle not greater than 30 degrees, and preferably not greater than about 10 degrees, to the horizontal with the inlet end of the tube lowermost and wholly submerged in the coagulating liquid, the tube being disposed in the spinning bath so that the slit is positioned upwardly, the angle between the vertical longitudinal plane passing through the axis of the tube and the plane containing the axis of the tube and the slit not exceeding about 45 degrees, and preferably about 10 degrees, the tube being movably mounted in the spinning bath so that it may be placed in position after initiation of the spinning operation, and the filament bundle entering the tube sideways through the slit during positioning of the tube into its operating position.  The interior diameter of the tube is preferably about the same as, or slightly larger than, the diameter of the outer ring of orifices in the spinneret or of the cross-sectional area of the bundle of filaments.  The spinning tube may be 6-36 inches long, may be about 1/2 inch internal diameter, and may have a trumpet-shaped inlet.  The width of the slit may be 1/32 to 1/8 inch, preferably about 1/16 inch.  The exit end of the tube preferably protrudes slightly above the surface of the bath, the surface of the bath covering about 1/4 to 3/4 of the exit.  The slit tube facilitates the initial threading of the filaments through the spinning tube.

Title: Gravitational oil and water separator
IPC: B01D17/04
Filed: 1976-08-11
Abstract: 1521629 Liquid separator NATIONAL MARINE SERVICE INC 11 Aug 1976 [29 Aug 1975] 34834/77 Divided out of 1521628 Heading BID A gravity separator for separating oil and water, e.g. from a ship's bilge, comprises a closed tank 10 with an inlet 12, 14 directed towards the underside of a member 30, beneath which the oil accumulates while water passes downwards through duct 102, up through non-return valves 112 and outwards through concentric, oleophobic, woven or knitted coalescer sleeves 100, which coalesce residual oil so that it remains in the tank while the water leaves by outlet 16 to pump 18. Before use the tank is filled with clean water from inlet 28, so that the space above member 30 remains filled with water and accumulating oil beneath member 30 lifts the member against the action of weights (see Specification 1521628). Bilge water is subsequently drawn into tank 10 via non- return valve 15 and inlet 12, 14 by the suction created by water-discharge pump 18, valves 28 and 41 being closed. When enough oil has accumulated to lift member 30 sufficiently to actuate upper magnetic switch 88, this causes control unit 22 to stop pump 18, close valve 19 and open valve 28 so that clean water under pressure enters tank 10 at 16, cleaning sleeves 100 by reverse flow and passing up through non-return valves 114, carrying any oil retained by the sleeves with it. The valve 15 prevents flow back out of the inlet 12, 14, so the incoming water displaces the accumulated oil through outlet 36, 38 and non-return valve 41 to storage 40. As the member 30 is no longer maintained buoyant by the oil, it falls and actuates lower magnetic switch 86, which closes valve 28, opens valve 19 and starts pump 18 to begin the separating cycle again. A detector 120 actuates an alarm and shuts down the separator if it detects excess oil at a level half-way up the tank. Member 30 is shown as a free-floating inverted cup. Figs. 3, 4 (not shown) illustrate alternative members, namely a flat disc and a cup which are connected to the tank wall by impervious bellows. In Fig. 4 the space above the cup may be isolated from the lower part of the tank by a further bellows which transmits pressure variations but does not allow liquid flow. Reference has been directed by the comptroller to Specification 1469204.
Patent GB-490665-A (GB)
Title: Manufacture of tanning materials
IPC: C14C3/20
Filed: 1936-12-18
Abstract: Tanning-agents are obtained by combining (a) a synthetic tanning-agent of the sulphonic acid type, or (b) a tanning-agent comprising a phenol-aldehyde condensation product condensed or peptized with an aromatic sulphonic acid which itself has only a weak tanning action, with (c) a phenol-aldehyde condensation product prepared in the presence of a sulphite under conditions which yield a product of insufficient solubility for use as a tanning-agent per se. Suitable components of type (a) are obtained by sulphonating phenol, cresols, naphthalene, or alkyl- or aralkylnaphthalenes and condensing the products, if necessary, with formaldehyde.  A suitable component of type (b) is prepared by condensing naphthalene-sulphonic acid at about 80 DEG  C. with a water-insoluble phenol-formaldehyde condensation product. Suitable components of type (c) are obtained by condensing phenol, cresols, xylenols, naphthols, dihydroxydiphenylmethane or dihydroxydiphenylethane with formaldehyde or acetaldehyde and a sulphite under conditions which yield a product containing 5-6 per cent of sulphur.  In the examples: (1) a condensation product from sulphonated phenol and formaldehyde is mixed with a product, containing 5-6 per cent of sulphur, obtained from commercial cresol, formaldehyde and sodium sulphite; (2) a condensation product from b -naphthol, commercial cresol and formaldehyde, prepared in the presence of sodium carbonate, is heated with a sulphonation product of commercial cresol, and the product is mixed with a product obtained from commercial cresol, formaldehyde, and sodium sulphite.  Specification 171,729, [Class 2 (iii)], is referred to.

Title: Improvements in electric circuit breakers utilising an arc-extinguishing medium
IPC: H01H33/70
Filed: 1953-12-16
Abstract: 735,555. Oil-break switches; actuation of switches. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Dec. 16, 1953 [Dec. 31, 1952], No. 34990/53. Class 38 (5). The moving contact 2 of an oil-blast circuit-. breaker is actuated by a pull-rod formed partly of insulating material 8, and connected at its lower end to the rod of a piston 9 driven by compressed air at a speed which is regulated in accordance with the magnitude of the current to be interrupted. The rod passes through an insulator 10 filled with oil and on downward movement of the rod to open the breaker, a shoulder 6 on contact 2 engages the base of an arc-extinguishing piston 5 which is pulled downwards to cause a flow of oil through the outlet opening of the piston which extinguishes the arc. The means for regulating the speed of piston 9 comprises a valve 14, Fig. 2, in the air supply which is acted on by opposed bellows 15, 16. Bellows 15 is influenced in the closing direction of the valve by a spring 17 and bellows 16 is influenced by an electromagnet 18 fed from a current transformer 19 having its primary winding connected in the breaker circuit. If the current to be broken is weak, the valve opening is determined solely by spring 17 which gives a fixed minimum opening, whereas if the current is heavy, electromagnet 18 overcomes the spring 17 and produces a suitable valve opening.
