Abstract: 315,152. Hargreaves, H. Oct. 10, 1928. Tension-arrangements; clearing-apparatus.-In a machine for winding yarns or threads the yarn x, Figs. 1 and 2,.is tensioned by passing through a ring 19 slidably mounted on a rod 8, the rod being adjustable in a slot 7 so as to be set parallel to or at an angle to the winding spindle 17 according as cylindrical or conical packages are being wound. An arcuate drag-plate 20 adjustably hinged at 21 may be provided above the rod 8 and a fixed drag-plate 14 having a rounded edge 15 between the rod and the traverse guide 16, the yarn passing successively over or through the members 20, 19, 14, 16 to the package 23. During winding the ring 19 is traversed on the rod 8 and the yarn tensioned thereby the reversal at the end of each reciprocation of the guide 16 resulting in increased tension and a firm ended package 23. The ring 19 also effects a clearing of the yarn. In winding conical packages the rod 8 is set at an angle to the spindle 17, Fig. 4, whereby the drag over the edge 15 of the plate 14 is greatest when the ring 19 approaches the nose of the cone. To assist in forming the nose dished inwardly a bent plate 27 mav be secured to the plate 14 to arrest the ring 19 in its travel towards the nose. The ring 19 may be an annular member or may be formed as an eye 28, Fig. 5, when winding doubled yarns.

Patent GB-952499-A (GB)
Title: Preparation of thorium oxalate
IPC: C07C51/41
Filed: 1961-08-14
Abstract: Thorium oxide of high packed bulk density is made by calcining thorium oxalate in either the dihydrate or hexahydrate form, which is prepared by the process of the invention (see Division C2), and which has a packed bulk density of at least 1.0 gms. per c.c.  The preferred temperature for calcining the dihydrate is 600 DEG  C.  In an example the oxide produced has a packed bulk density of 3.2 gms. per c.c. and, in a series of experiments expressed in tabular form, the oxides obtained have packed bulk densities varying from 2.0 to 3.3 gms. per c.c.ALSO:Thorium oxalate, of relatively high bulk density, is made by feeding an aqueous solution of a thorium salt, with a pH of below 4, into an oxalic acid solution to form a reaction mixture which is maintained at 40 DEG C. and upwards and adding thereto, whilst thorium oxalate is precipitated, a monovalent cation in an amount directly proportional to that of the thorium within the range of 0.5 to 15 moles of cation per mole of thorium added to the acid solution. A dense thorium oxalate has a packed bulk density of at least 1.0 gms. per c.c. Preferably the thorium solution contains at least 0.05% by weight of thorium as Th+4 and not more than 2-5 moles of cation per litre of aqueous solution and 4 to 6.5 moles of cation per mole of thorium are present.  Preferably solutions containing about 10% by weight of oxalic acid are used.  The cation may be added as a constituent of the aqueous thorium solution.  If the hydrogen ion concentration of the thorium solution is above 10N it is partially neutralized e.g. with sodium hydroxide.  Sodium, potassium, lithium and ammonium cations, and mixtures thereof, are specified. Thorium sulphate, chloride and nitrate are specified thorium salts.  If the cation is added as an oxalate the cation containing, and thorium containing, solutions should be added simultaneously at a rate such that the cation to thorium ratio remains substantially constant within the above range. In an example an aqueous solution of thorium and sodium sulphate is added, at 80 DEG C., with agitation, to an oxalic acid solution, the thorium hexahydrate being filtered off and dried to form the dihydrate with a packed bulk density of 1.37 gms. per c.c.  The oxalate may be calcinied to the oxide with a packed bulk density of 3.2 gms. per c.c. (see Division C1). Other salts used are sodium chloride and nitrate, ammonium chloride and sulphate, and potassium and lithium sulphate. The results of a number of experiments illustrating various changes in the reaction conditions, and salts used, are shown in tabular form, the packed bulk derivatives of the oxalates obtained varying from 1.0 to 1.37 gms. per c.c.

Title: Improved process for the manufacture of phenol formaldehyde condensation products
IPC: C08G8/28
Filed: 1927-11-03
Abstract: 290,963. Kunstharzfabrik Dr. F. Pollak Ges. May 21, 1927, [Convention date]. Phenol-aldehyde condensation products.-Colloidal solutions of phenol-aldehyde resins obtained according to Specification 267,901 are freed from water by distillation, with or without the addition of solvents such as glycerine or glycol, so that the final hardened products are transparent and opalescent. Glass-clear products may be obtained by suitable choice of acid for neutralizing the alkaline condensing agent. Most acids may be used when organic bases are employed for condensing. When strong inorganic bases are used as condensing agents, organic acids having a dissociation constant of 10<-2>-10<-5> whose alkali salts are water-soluble, and particularly such acids which, in addition to a carboxyl group, contain another salt-forming group are used. Di-, poly-, oxy-, or sulphocarboxylic acids or alcohol acids such as mandelic acid are suitable in this connection. In examples, when piperidine is used as a condensing agent, hydrochloric acid is used to neutralize it, and when potassium hydroxide is used as the condensing agent, lactic or phthalic acids are used as neutralizing agents. Salts which react with the phenol to form phenolates such as carbonates of alkalis or of organic bases may also be used as condensing agents. The condensation may be initially effected in acid phase, provided the alkaline phase is introduced before the distillation and neutralization. Solvents or diluents such as glycerine or alcohol may be introduced into the mixture, to produce more workable products or to aid the water extraction process. Instead of phenol and formaldehyde, other phenols and aldehydes and their polymers may be used, Examples of the process and its modifications are given. The Specification as open to inspection under Sect. 91 (3) (a) describes also distillation under vacuum or with a greatly increased surface of the condensation solution. This subject-matter does not appear in the Specification as accepted.
