Title: Improvements in or relating to the production of alkylol-substituted alkyl or alkaryl guanidines
IPC: C07C277/08
Filed: 1947-10-15
Abstract: Alkylol substituted alkyl or alkaryl guanidines are obtained by reacting an alkylene oxide, e.g. ethylene oxide with an alkyl or alkaryl guanidine.  Suitable guanidines are ethyl, propyl, isopropyl, n-butyl, isobutyl, amyl and higher guanidines such as dodecyl, tetradecyl, hexadecyl and octadecyl, N,N-diethyl, dipropyl, dibutyl, dihexyl or dioctyl guanidines, N - dodecyl - N1 - octadecylguanidine and N - dodecyl - N1 - methylguanidine, p - butylphenylguanidine, p - amylphenylguanidine, 2 : 4 - dibutylphenylguanidine, 2 : 4 - diamylphenylguanidine and 2 : 4-diamylphenoxyethylguanidine. Preferably the reaction is carried out in the presence of an organic solvent at a temperature between 50 DEG  and 150 DEG  C.  Detailed examples are given.  Specification 604,351 is referred to. Monosubstituted guanidines containing an alkyl chain of 8-18 carbon atoms, are obtained by reacting the corresponding primary amine with an aqueous solution of cyanamide in the presence of acidic material, e.g. acetic or hydrochloric acid.ALSO:Alkylol substituted alkyl or alkaryl guanidines which are cation-active wetting agents are obtained by reacting an alkyline oxide, e.g. ethylene oxide with an alkyl or alkaryl guanidine.

Abstract: 938,390. Feeding sheets. TELEFUNKEN PATENTVERWALTUNGS-G.m.b.H. July 3, 1961 [July 30, 1960], No. 27709/61. Class 100 (1). [Also in Group XXX] In a suction belt apparatus for separating sheets or sheet-like objects from a stack, or for feeding them from a collecting position to a delivery position, and wherein the belt is apertured and travels over an apertured plate 6 of a suction chamber, the plate 6 has suction apertures 5 extending from the collecting to the delivery position but which have a larger area at the collecting position than at any corresponding portion of the rest of the transport path of the sheets. As shown, the apertures 5 at the position where a sheet is picked up have a width b, as opposed to a narrow slot of width c along the rest of the length of the plate. Thus, a greater suctional force is applied at the pickup position of a sheet; and if a sheet is not picked up, the intake of air into the suction chamber is greatly reduced as the apertures in the belt move over the narrow slots c. The three apertures 5 need not be of the same size. The suction chamber behind the plate 6 may be subdivided into sections which are each connected to a common suction plant.

[Classes 23 and 82 (ii)] [Also in Group I] To separate heavier matter from a liquid, such as a suspension of paper pulp or china clay the liquid is introduced under pressure from a pipe 11 through a tapered nozzle into a spiral channel 12 surrounding an outlet tube 13 in a receptacle 15, so that it is caused to flow down spirally in the outer portion of the vessel and the heavier matter is separated centrifugally. From the lower end of the receptacle the suspension of the lighter matter rises, still moving spirally, as a central core and passes away through the tube 13. The spirally-flowing columns are contracted at the centre by means of. disc 17 with a central aperture 18.

Abstract: 206,849. Fabrik Elektrischer Apparate F. Sauter Akt.-Ges. Nov. 10, 1922, [Convention date]. Switches, quick-action; electric motor actuation.-Operation of a switch 33 by hand or by clockwork from one position to the other causes a switch 12 to be driven bv an electric motor rapidly on or off. Operation of the switch 33 completes the circuit to a motor 1 which rotates a shaft 2 connected by a spiral spring 5, a rod 23 and a disc 20 to a shaft 9 carrying the switch arms 12. Rotation of the shaft 9 is prevented by one of two diametrically opposed inclined lugs engaging a pin 28 on a rocking-member 24 pivoted at 25, until the upper end of the pin 28 is lifted by one of two diametrically opposed inclined lugs 7 on a disc 6 on the shaft 2. The shaft 9 then rotates through 90‹ till the lug 21 engages a pin 29 on the member 24. This rotation breaks both the main circuit 14 and the motor circuit 16, 17. The motor circuit may be closed again by movement of the switch 33 to its other position, when the switch arms 12 will be moved through another 90‹.

Title: Improvements in processes for sulphonating higher aliphatic carboxylic acids and their esters
IPC: C11C3/00
Filed: 1935-10-17
Abstract: In the sulphonation of higher aliphatic carboxylic acids and their esters, three or more sulphonating agents of different strengths are employed successively in three or more stages, beginning with the weakest in small quantity and continuing with a stronger agent, increasing the quantity of the latter if necessary.  Simultaneously, with the sulphonation, the carboxylic acids may be condensed with alcohols or aromatic hydrocarbons.  In examples: (1) castor oil is treated successively with monohydrate, 10 per cent oleum and 30 per cent oleum at temperatures rising from 20--35 DEG  C.; (2) a mixture of coconut oil, palm oil fatty acid and naphthalene is treated with 96 per cent sulphuric acid, 10 per cent oleum and 20 per cent oleum; the product is then added gradually to 20 per cent oleum and worked up in the usual manner; (3) a mixture of coconut oil and glycerine is treated with monohydrate, 10 per cent oleum, 20 per cent oleum and 30 per cent oleum.  The Specification as open to inspection under Sect. 91 comprises also further examples: (1) coconut oil and hydrogenated train oil are sulphonated by treatment with 96 per cent sulphuric acid, monohydrate and oleum of 10 per cent and 20 per cent strength; (2) a mixture of tallow-like waste fat and glycerine is treated with 96 per cent sulphuric acid and with monohydrate and is then subjected to two treatments with oleum.

Title: An improved process for dressing artificial silk
IPC: D06M13/368
Filed: 1933-10-18
Abstract: In treating artificial silk with drying oils for the purpose of producing film-like coatings water-soluble non-volatile organic bases such as mono-, di- or tri-ethanolamine are incorporated with the artificial silk prior to treatment with the dressing agent in order to counteract the detrimental effect of products formed from the drying oils.  The silk is treated with a water solution of the base, e.g. tri-ethanolamine hydro extracted and dried, and then with a solution of linseed oil in benzene.  Oils or waxes may be added to the drying oils, e.g. castor oil, lanoline &c. for softening purposes, and in order to avoid too rapid drying anti-oxidants, e.g. naphthols, hydroquinone &c.  The drying may also be accelerated by treatment with oxygen, or ozone.

Abstract: 1,268,531. Measuring surface roughness. CENTRE NATIONAL DE RECHERCHES METALLURGIQUES. June 9, 1969 [June 7, 1968], No.29042/69. Heading G1A. Surface roughness # of a sheet material is measured by projecting a beam of radiation on to the sheet at a small angle to the normal to the sheet and detecting the reflected radiation in a direction making another small angle to the sheet. The surface roughness # is defined by the expression #1/L y<SP>2</SP>dx where L is the length of a line over   which the integral is evaluated and y is distance of departure from smoothness of the surface. The apparatus is calibrated on a specimen of perfect smoothness and the relation between the value # and the reflected light determined experimentally. Preferably the angle of the incident light and the angle of the reflected radiation detected are equal. Alternatively two detectors may be arranged to detect light reflected at different angles to the normal in which case the ratio of the detected intensities is a function of surface roughness, the function being experimentally determined. If the plane of the sheet is liable to move e.g. due to impacts or vibrations, the light emitter-detector assembly is arranged to rotate relative the point of impact of the incident light beam and the maximum value of output signal determined.
