Abstract: 1,195,172. Anthraquinone dyes. UGINE KUHLMANN. 22 April, 1968 [21 April, 1967], No. 18854/68. Heading C4P. The invention comprises compounds of the formula where X is a hydrogen atom or a sulpho group in the 5, 6, 7 or 8 position, M is a monovalent cation and A is an alkylene radical with a straight or branched chain containing at least 3 carbon atoms, or is a group of the formula where B 1  and B 2  are direct bonds or alkylene groups and the cyclohexylene ring may be substituted by alkyl groups. The compounds are prepared by condensing together compounds of the formulµ in aqueous or aqueous-alcoholic medium in the presence of a copper-based catalyst. Compounds of Formula (IV) are prepared by react. ing compounds of Formula (III) with a diamine of the formula H 2 N-A-NH 2  so that a single amino group enters into the reaction. Alternatively, excess of the diamine may be reacted with a compound of Formula (III) to give compounds of Formula (I)

Abstract: 1498139 Ion-exchange resin regeneration CLARKE CHAPMAN Ltd 19 March 1976 [7 May 1975] 19077/75 Heading B1J In a method of ion-exchange using a mixed bed of anion- and cation-exchange resins, cleaning and/or regenerating the bed comprises separating the anion and cation resins into upper and lower layers respectively, causing a downward flow of water through the anion resin layer and a horizontal flow of water above a number of horizontal bars positioned at the interface between the anion resin layer and the cation resin layer, the bars being disposed transversely of said horizontal flow, to convey the anion resin from the bed, adding cleaned and/or regenerated anion resin to the bed, and mixing the anion resin with the cation resin. The horizontal flow may be across the vessel from one side to the opposite side, or inwards from a "ring-main" to an outlet at the centre of the vessel. The initial separation into two layers may be by an upwards flow of liquid and the cation exchange resin may be regenerated in situ after removal of the anion exchange resin for regeneration in another vessel.

Title: Improvements in or relating to methods of making sulphenamides
IPC: C07D277/80
Filed: 1947-07-17
Abstract: Sulphenamides are prepared by the oxidation in a wholly aqueous medium of a mixture of a free mercaptothiazole and at least three molecular proportions of a primary amine stronger than ammonia. The following amines are mentioned: benzylamine, ethylene diamine, n-butylamine, n-amylamine, ethylamine, propylamine, allylamine, and hexahydrobenzylamine.  Mercaptans such as 2-mercaptothiazoline, 2-mercapto-4-ethylthiazole, and 2-mercapto-4 : 5-dimethylthiazole may be used; particularly preferred are mercapto-arylthiazoles such as 2-mercaptobenzothiazole, 2-mercaptonaphthothiazole, 2-mercaptomethylbenzothiazole, and 2-mercaptochlorobenzothiazole. Hypochlorites, e.g. alkali metal salts, are the preferred oxidizing agents, although other compounds may be employed such as hydrogen peroxide, chlorine, potassium ferricyanide and potassium persulphate. In the examples, a suspension of mercaptobenzothiazole in water is oxidized with sodium hypochlorite solution in the presence of (1) cyclohexylamine to give cyclohexylaminothiobenzothiazole; (2) sec.-butylamine to give sec.-butylaminothiobenzothiazole; (3) monoethanolamine to give b -hydroxyethylaminothiobenzothiazole; (5) o-cyclohexylcyclohexylamine; and (6) methylamine; in (4) cyclohexylamine is oxidized under the same conditions with hydrogen peroxide.  The Specification as open to inspection under Sect. 91 comprises the statement that any organic mercaptan may be used in the reaction, which may be performed in an inert organic solvent. Specified mercaptans are thiophenol, thio - b  - naphthol, 2 - mercapto - 4 : 5 - dihydroglyoxaline, 2-mercaptobenzimidazole, and 2-mercaptobenzoxazole.  This subject-matter does not appear in the Specification as accepted.ALSO:Sulphenamides, made according to the process of the Group IV (b) Abridgment, and of formula R.S.NHR1 (where R is a thiazolyl radical, e.g. benzothiazolyl, and R1 is organic) are used as accelerators for the vulcanization of rubber; they may be employed alone or in conjunction with basic nitrogen-containing accelerators, e.g. di-o-tolylguanidine and diphenylguanidine phthalate.  In an example, pale crepe rubber mixed with zinc oxide and stearic acid is vulcanized in the presence of b -hydroxyethylaminothiobenzothiazole and diphenylguanidine.  The Specification as open to inspection under Sect. 91 comprises also the use of sulphenamides R.S.NHR1, where R is any organic group, e.g. phenyl, b -naphthyl, 2-benzimidazolyl, 2-benzoxazolyl and the radical derived from 4 : 5-dihydroglyoxaline.  This subject-matter does not appear in the Specification as accepted.

Title: Ac arc welding current control apparatus
IPC: B23K9/073
Filed: 1974-05-03
Abstract: 1427107 Tap-changing systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 3 May 1974 19585/74 Heading HIT [Also in Division H2] In an A.C. arc welding system, the welding current is determined by selecting tappings on an inductor 1 by means of a reversible electric motor 71 controlled by detecting means 72 responsive to two different levels or polarities of voltage or current in the inductor 1, respectively to determine the direction of rotation of the motor 71. In Fig. 1, the terminals A, B of inductor 1 are connected in series with the arc, the value of inductor 1 being determined by fine and coarse motor-driven switches driven by shafts 39 and 43. When it is desired to increase the welding current, a so-called welding pencil is positioned between the electrode and the workpiece, the pencil comprising resistance, with or without a rectifier and causes a current of a predetermined polarity or magnitude in the inductor 1. This is sensed by current transformer 72 which energizes relay A, contacts A1 of which energize the forward windings 77, 79 of motor 71 which is geared to a shaft 39, driving the fine tapping selector 5. An arm 62 on shaft 39 causes a disc 51 to rotate the coarse switch 6 by one step for each revolution of shaft 39. The first predetermined current is maintained until the correct combination of tappings is reached on inductor 1. The current is reduced by selecting a second predetermined direction or magnitude of current so that relay B is energized, energizing the reverse windings 78, 79 of motor 71. Limit switches 55a, 56a are provided. Reference is made to Specification 938,132 in which the welding current is so much greater than the control current that saturation of the current transformer 72 occurs, preventing control of the motor 71 by the welding current.

[Class 83 (iv).] Feeds for rolling-mandrel carriages.-In pilger rolling mills the rotation of 90‹ given to the work by the helically grooved spindle g working in the nut i can be kept constant throughout varying stroke length of operation for varying sizes of tubes and so avoiding changing the spindle g for another of different pitch, by mounting the nut i in a housing h so that on the working stroke it is slid up against the adjustable abutment n by jaws l frictionally gripping the spindle g, further movement causing the nut i to rotate until the stroke finishes when the nut i is clamped in position by the ratchet k. The abutment n is adjusted by a hand-wheel thus determining the amount of turn given to the nut. In Figs. 3 and 4 the housing h does not move longitudinally but rotates with thenut i through the clamp l bearing frictionally against the side of the housing. In rotating during. the working stroke it freely moves the dashpot piston p against the free exit of oil through the piston flap valve S the arm o coming against a fixed abutment q. On the return stroke the pawl u engages nut i which drags the housing h round with it against the heavy resistance of the dashpot until its arm o comes against an adjustable stop r, which determines the amount of turn given to the nut. Another adjustable modification is also described.
