Abstract: 477,621. Centrifugal dust-separators. BOVING, J. O., and REEVES, H. C. July 14, 1936, No. 19573. [Class 23] In a cyclone dust-separator a with a dustcollecting chamber f additional to the cyclone chamber, the axial region of the vortex in the cyclone chamber is connected by the pipe h to the top of the dust-collecting chamber. The pipe passes through the opening c in the conical lower part b of the separator The dust-laden gas enters by the tangential inlet d or past inclined guide vanes, and the passage of the separated dust through the opening c is assisted by the suction of the whirling gas on the pipe h which reduces the pressure in the dust-collecting chamber f. The effect of the suction can be adjusted by the valve i in pipe h. A discharge valve g is arranged at the bottom of the chamber f, and a sheet of wire gauze prevents dust from passing back to the separator through the pipe h. A tapper k is associated with the wire gauze j. In a modification, a conical partition l, Fig. 2, between the separating chamber a and the dust-collecting chamber f has a short suction pipe m in the axial region of the vortex. Its effect is varied by a hand operated valve cone n and the wire gauze partition is fitted across the base of the partition l and is provided with a tapper k.

Abstract: 934,056. Making universal joints. METALASTIK Ltd. April 13, 1961 [June 2, 1960], No. 19577/60. Class 83 (2). [Also in Groups XXIV and XXXII] In a method of manufacturing a ball point an inner ball-like part 13 is located in the required position within a sleeve 15, 16 which constitutes a housing but is larger than finally required, unvulcanised rubber 14 is forced into, to fill, the space between the sleeve part and the ball-like part and then cured so that it becomes bonded to the sleeve 15, 16 and the ball-like part 13 the sleeve 15, 16 being finally reduced in size, e.g. by swaging, to compress the rubber 14. As shown, a universal coupling comprises an annular disc 10 having two pairs of uniformly spaced ball joints on a common pitch circle each joint including a hollow rod 12 having a part-spherical protruberance 13. The disc 10 is formed of two annular metal discs secured together by swaging, bolting, riveting, or welding, the cup-like portions 15, 16 being formed as oversize pressings as shown in chain dotted lines. The swaging operation displaces inwardly only the non-spherical parts of the cups 15, 16. Alternatively the cup-like parts may be partspherical throughout but oversize in which case they are uniformly reduced in size. Only one of the cup-like portions of each pair may be oversize. In a modification the annular disc 10 is a one-piece die-casting, or forging, having integral sleeve parts which may be cylindrical, or shaped like a pair of cup-like portions in their initial form, and which extend at right angles from each side of the disc. After the moulding operation the sleeve parts are swaged to form spherical housings for the ball joints. Alternatively the complementary cup-like portions may be initially of cylindrical form. Where a sleeve part is in one piece one end may be cylindrical and the other cup-like which may be in its final form. The method described may also be used to manufacture tangential coupling links for universal couplings. Specification 931,860 is referred to.

Abstract: 314,543. Kohorn, Oscar. Freiherr von, (trading as Kohorn & Co., O.), and Schupp, H. June 30, 1928, [Convention date]. Right to Patent relinquished. Cellulose carboxylates, processes for making filaments from.-For the manufacture of hollow filaments by the dry spinning of solutions of cellulose acetate or other cellulose esters, there is added to the spinning solution a strongly-acting precipitant for the cellulose acetate &c. in quantity, usually not less than 30 per cent of the weight of the cellulose acetate &c., such that there is formed on the extruded filaments a firm skin, which is stretched during the escape from the still-fluid core of the enclosed solvent. The precipitant may be a single liquid or a mixture of liquids. The characteristics of the product may depend on the size of the internal cavities of the filaments; these can be varied by adjusting the proportion of the added substance, and by variation of the spinning conditions; with the large cavities, the product is dull and lustreless, while with decrease in the size of the cavities the lustre increases; it is possible to attain a product having half-matt lustre and the appearance and feel of wool. In examples, hollow cellulose acetate filaments are made by spinning solutions containing acetone, toluene, and water, or acetone, alcohol, and benzine. The Specification as open to inspection under Sect. 91 (3) (a) refers to the addition to the spinning solution of any substance, particularly a non-solvent for the cellulose ester, which is capable of producing a firm skin on the extended filaments. This subject-matter does not appear in the Specification as accepted.

Food for animals. - Cereal mill by-products such as bran, chaff, or any by-product of wheat, oats, or other grains not usually worked into flour, with grain screenings and alfalfa meal are ground very fine and mixed with approximately 5 per cent of cotton-seed meal. The mixture is then thoroughly saturated with molasses in a heated condition. The mixture is then fed into a machine from which it is forced in the form of strings. The strings are cut up and coated in a shaker machine with another 5 per cent of cottonseed meal, remaining in the shaker machine for from two to three minutes. The resulting coated pieces are again passed through a machine to form the material into strings, cut into short lengths and coated with cotton-seed meal in the shaker machine. The feed is then dried bv air for about ten minutes to form a hard casing about each of the particles and if necessary re-coated with cotton-seed meal. As a specific example the following percentages by weight of materials may be used: molasses. 25-55 per cent; cotton-seed meal, approximately, 12 per cent; mill by-products, approximately, 18 per cent; grain screenings, approximately, 5 per cent ; alfalfa meal. approximately, 10 per cent. In a modified method of producing the food the mixture with the molasses is allowed to stand for about twenty-four hours and is then forced through apertures to form strings. These are cut into short lengths and immediately rolled in a shaker machine with cotton-seed meal. They are then coated and dried slightly and in cold weather may be sacked and stored immediately. In hot weather the particles are dried at a temperature of 400‹ F. for approximately ten minutes and then if necessary re-coated with cotton-seed meal. To give a further heavy coating of the meal if desired the particles are dropped through a box in which a molasses spray is projected and then again rolled in the cotton-seed meal.
