Title: Improvements in or relating to the production of naphthalenedisulphonyl chlorides
IPC: C07C309/86
Filed: 1955-02-07
Abstract: 1 : 5-Naphthalenedisulphonyl chloride is prepared by adding chlorosulphonic acid to a -naphthalene sulphonic acid, the amount of chlorosulphonic acid being in excess over the molar equivalent, allowing the reaction to proceed so as to form insoluble 1 : 5-naphthalenedisulphonyl chloride, and separating said chloride, which may have admixed therewith a minor proportion of 1 : 6-isomer, from the final reaction mixture.  The a -naphthalene sulphonic acid may be prepared in a first stage by reacting naphthalene with sulphuric acid, preferably of between about 90 and 96 per cent concentration.  The reaction with chlorosulphonic acid is preferably conducted at temperatures not in excess of 35 DEG  C.  Two methods of separation are specified.  Method A gives a higher yield than method B of a product which contains some 1 : 6-isomer.  Method B gives the substantially pure 1 : 5-isomer. These methods are illustrated in the examples.  Naphthalene (1 mol.) is reacted with sulphuric acid (2 mols.) to give a mixture containing a -naphthalene sulphonic acid to which chlorosulphonic acid (8 mols.) is slowly added and the mixture allowed to react further at 30 DEG  C.  The 1 : 5-naphthalenedisulphonyl chloride crystals are separated from the reaction mixture by (a) hydrolysing the reaction mixture with ice, washing the insoluble material with water, filtering and drying, or (b) filtering the reaction mixture, washing the residue on the filter with water and drying; chlorosulphonic acid being recovered by distillation from the filtrate.  Specification 802,655 is referred to.

Patent GB-955894-A (GB)
Title: Method for increasing the concentration of oxygen in air
IPC: B01D53/02
Filed: 1962-01-31
Abstract: A method of increasing the content of oxygen in air comprises selectively adsorbing nitrogen therefrom by periodically contacting air at constant pressure and at -30 to 40  DEG c. with a molecular sieve zeolite, the pores of which have a diameter of at least 4 ngstrom, and regenerating the zeolite at -30 to 40  DEG C. Zeolites used are preferably of sodium-calcium or sodiumstrontium aluminosilicates, for example "Linde 5A" (Registered Trade Mark), in which the negatively charged lattice zones of the aluminosilicate structure are about two-thirds saturated by calcium ions and about one-third by sodium ions.  Nitrogen adsorption may be effected at a pressure of between 1 and 5 atmospheres gauge, and regeneration is then effected by reducing the pressure to atmospheric; further regeneration may then be effected by pumping off adsorbed gases. Alternatively nitrogen adsorption may take place at normal pressure, whereupon regeneration is effected by pumping off adsorbed gases. Specifications 777,232 and 777,233 are referred to.

Title: Improvements in or relating to resinous condensation products and coating compositions
IPC: C08G8/28
Filed: 1932-02-11
Abstract: Resinous products are obtained by reacting together, in the presence of an alkaline catalyst, an oxidized drying oil, about an equal amount of a phenol or hydrogenated phenol, a natural resin, and an aldehyde, the molecular ratio of aldehyde to phenol or hydrogenated phenol lying between about 1 and 0.25.  As the phenolic component there may be used ordinary phenol, a cresol, cresylic acid, a naphthol, or cyclohexanol; the oxidized drying oil may be oxidized or blown tung oil, linseed oil, perilla oil, soya bean oil, or fish oil; the natural resin may be colophony or Manila copal; the aldehyde may be formaldehyde, acetaldehyde, or benzaldehyde; the catalyst may be ammonia or a caustic alkali or alkali metal carbonate.  In an example, oxidized linseed oil is dissolved in the warm in an equal amount of commercial phenol, and the solution is treated with commercial resin and formaldehyde solution (about 0.7 mol. calculated on the phenol), with addition of a little ammonia; the mixture is heated under reflux and the water then distilled off.  The products are soluble in hydrocarbon oils and drying oils, and are useful as varnish bases, preferably in association with plasticizers such as tricresyl phosphate or castor oil, and driers such as manganese dioxide or resinates. The Specification refers to prior methods, for making resins of similar properties, comprising (1) condensing phenol and formaldehyde in about equimolecular amounts in the presence of oxidized drying oils and an alkaline catalyst; (2) condensing a phenol with 0.5-1 mol. of an aldehyde in the presence of oxidized drying oils (other than tung oil) and an alkaline catalyst.

Title: A device for stacking or uniformly enmeshing coil or helical springs
IPC: B21F33/04
Filed: 1961-02-06
Abstract: 911,398. Orientating and stacking springs. SPUEHL A.G. Feb. 6, 1961 [Nov. 23, 1960], No. 4318/61. Class 78 (1). A plurality of springs 11 are stacked together (after manufacture) into assemblies by a mechanism which includes arm 12, slide 14 and plate 38. Thus a spring 11 is pushed into the position shown from the left by arm 12, and the arm then operates hook 13 to release the spring before the arm is then retracted. Slide 14, which is reciprocated along passage 1 by rocking arm 25, then moves to the right and engages the spring at 19 to move it one step to the right. As it does so, the knot of the spring is engaged by plate 38, the plate 38 being carried by arm 29 pivoted at 31, and being oscillated when roller 32 is engaged by cam 36 carried by slide 14, so that the engagement of 38 with the knot of the spring rotates the spring about its own axis to a predetermined angular position. Then arm 12 likewise delivers the next spring to the position shown and the sequence is repeated, the slide 14 forwarding the spring to the right while simultaneously plate 38 engages and rotates the spring so that the second spring assumes the same angular orientation as the first and is intermeshed therewith. Likewise the next springs are delivered by bar 12, pushed by slide 14, and then rotated by slide 38, so that a spring assembly is completed having all the springs orientated similarly to give a compact mass.
