Abstract: 1,008,057. Double twist spindle. PALITEX PROJECT CO. G.m.b.H. Aug. 7, 1964 [Aug. 9, 1963], No. 32154/64. Heading D1D. A double twist spindle has a tubular guide portion 15 (Fig. 6) or 25 (Fig. 12) extending above the package 2 and pivotable in any direction, within the surface of an inverted cone, about a point on the spindle axis. In Fig. 6 tube 15 has a ball joint connection with a tube 21 slidably mounted in the top of the spindle. Ring magnets 17, 18 are mounted with opposed poles on the tube 15 and top of the spindle respectively so that tube 15 tends to a vertical position and tube 21 tends to rise out of the spindle. In other forms tube 21 is a stationary extension of the spindle (Figs. 2, 3, 4, 5, 8 not shown) while tube 15 may be curved (Fig. 4 not shown) or be formed with a mushroom-shaped upper flange (Fig. 5 not shown). In Fig. 12 a flange 23 is formed on tube 21 to carry a ring magnet 24 and an additional tube 35, flexibly supported by a leaf spring 36 is pivoted on the vertical tube 25 to receive the the upwardly moving yarn, alternatively tube 25 is replaced by a shorter tube with a ball joint at its upper end carrying a short auxiliary tube. Instead of magnets the tubes 15, 25 may be urged towards a vertical position by spring means or it may have a bell-shaped flange at its lower end such that it centre of gravity lies below the pivot point of the ball joint (Fig. 2 not shown). In a further form (Fig. 9 not shown) tube 15 is attached to a tubular extension of the spindle by a flexible collar; alternatively the tube itself is flexible and is formed as a spirally wound tube (Fig. 10 not shown) or as a series of flexible joints (Fig. 11 not shown). Various combinations of the different embodiments are also described.

Title: Process for the treatment of natural calcium carbonates, and the products obtained by this process
IPC: C01F11/18
Filed: 1952-12-19
Abstract: Natural calcium carbonate is ground in the presence of one or more fatty acids having at least 12 carbon atoms in the molecule at a temperature at least equal to that at which carbonic acid is displaced from the carbonate by said acid or acids, thereby forming an adherant coating of the calcium salt or salts of the acid or acids on the carbonate particles.  The acids are preferably those found in glycerides of animal or vegetable origin, and the proportion of acid may be from 0.1-10 per cent. by weight of the carbonate.  Several varieties of chalk are referred to, as well as calcium carbonates of "saccharoid structure" and of marble type.  The minimum temperature as a rule would be at least 80 DEG  C.  The heat may be supplied by preheated carbonate. The acid may be added as a fine rain or mist, or in the case of an acid solid at the temperature concerned, as a fine powder which is mixed with the carbonate before entry into the mill. The product is suitable as a filler for plastics and paints.ALSO:Natural calcium carbonate is ground in the presence of one or more fatty acids having at least twelve carbon atoms in the molecule at a temperature at least equal to that at which carbonic acid is displaced from the carbonate by said acid or acids to produce a free-flowing product.  The acids, which are preferably those found in glycerides of animal or vegetable origin, may be used in the proportion of 0.1-10 per cent by weight of the carbonate.  The minimum temperature normally would be at least 80 DEG C., heat being, if desired, supplied by preheating the carbonate.  The acid may be supplied as a fine rain or mist before, during orid shortly after the entry of the carbonate into the mill, or as a fine powder before or during said entry.

Title: Improvements in or relating to the treatment of hydrocarbon mixtures derived from coal
Inventor: MURRAY JAMES VINCENT
IPC: C10G1/04
Filed: 1959-09-22
Abstract: Hydrocarbon mixtures obtained from coal are treated with 2-20 mols of hydrogen per mol of feed at 525-700 DEG C. and 1,000-3,500 p.s.i.g. for less than 15 minutes in the absence of a catalyst to obtain mixtures which are more readily separable.  The principal reactions are stated to be dealkylation of alkyl aromatics, aromatisation, and cracking to gases of aliphatic compounds.  The materials to be processed may be coal distillates or fractions resulting from the destructive hydrogenation of coal.  Light oil fractions (boiling range 75-270 DEG C.) yield benzene, toluene, xylenes, ethylbenzene and naphthalene; the phenolic fraction which may be processed separately yields phenol and cresols.  Middle oils (boiling range 270-330 DEG C.) yields benzene, toluene, xylenes, ethylbenzene, naphthalene, methylnaphthalene, fluorene and phenanthrene.  Heavy oils (boiling above 330 DEG C. but excluding pitch) yields phenanthrene, carbazole, methylphenanthrene, fluoranthrene and pyrene.  Pitch can also be treated to obtain high boiling condensed ring aromatics.  The fractions may be treated separately or together with or without removal of phenols and nitrogen bases.  Continuous processes are preferred using tubular reactors, e.g. immersed in lead baths.

Title: Improvements in straight bar knitting machines of the cotton type
IPC: D04B11/00
Filed: 1948-12-18
Abstract: 673,947. Knitting. COLTON, L. N. (Thiede, W.). Dec. 18, 1948, No. 32784/48. Class 74 (ii). A straight-bar knitting-machine has driving means for the thread-laying and loop working mechanisms which enables the ratio between the time periods of operation per course of the thread laying or coulier mechanism and the loop working mechanism to be reduced for shorter courses of knitting. A motor 1 drives an intermediate shaft 2 from which the slurcock bar 17 and main cam-shaft 9 are driven alternately. The bar 17 is driven to right or left through one or other of bevel pinions 3, 4, secured to shaft 2 by whichever is appropriate of clutches 10, 11, a bevel gear 6, draw-cam 7, a rod 15, and a draw-lever 16. The cam-shaft 9 is driven through a clutch 12, and gears 5, 8. When one of bell-crank levers 26, 27 is on a low part of a slidable cam-bar 21, the associated clutch 10 or 11 will be engaged and the slurcock bar 17 will be traversed in one direction. Just before the slurcocks reach the edge of the knitted fabric, stops 19, 20 on the bar 21 will be adjusted by the narrowing mechanism and an abutment 18 traversed with the bar 17 will engage the appropriate one of these stops, to move the bar 21 into such a position that both clutches 10, 11 are disengaged and clutch 12 is engaged. The cam-shaft 9 now rotates but, as it completes the degree of rotation necessary for a loop drawing operation, a drum cam 25 on it moves the bar 21 to disengage the clutch 12 and engage the other of clutches 10, 11, so promoting the reverse traverse of bar 17. In a modification, Fig. 4, the slurcock bar 38 and cam-shaft 47 are driven by motors 29, 44 which are put into and out of operation singly and alternately by a switch 49 operated by a cam 48 on the shaft 47 and by a switch 43 operated by a slidable rod 42 carrying stops 40, 41 adjustable therealong by the narrowing mechanism and engageable by a projection 39 on the slurcock-bar 38. The slurcock f is advanced to the operative position by a cam 60 on a reciprocatable rod 61 and, when the rod is moved to the left, is retracted by springs 59 to allow the catch-bar to come back. The rod 61 is reciprocated by the slurcock bar 17 (or 38) but, in order to reduce the amplitude of reciprocation to that necessary, the slurcock bar is coupled to the bar 61 through a sleeve 64 slidably keyed to a shaft 63 and a helical ring 67 which engages a notch in a plate 68 on the rod 61. The shaft 63 is rotated, at the required intervals, from a cam on the main cam-shaft of the machine.
