Title: Marking ribbon
IPC: G08B5/00
Filed: 1966-08-05
Abstract: 1,142,570. Ornamenting. FABRIQUE DE SOIERIES ANDRE & SERGE FERRARI. 5 Aug., 1966 [8 Oct., 1965], No. 35176/66. Heading B6G. [Also in Division G5] A marking ribbon comprises a fabric material of which each of the two faces has a pattern consisting of colour zones of a colour different from the colour of the material, the colour zones of the two faces being arranged so that they do not coincide, so that when the ribbon is stretched between two fixed points and is acted upon by wind and air currents the two faces become visible alternately and produce a flickering effect. A method of manufacturing such a ribbon includes the steps of colouring opposite faces of a flexible material with oblique spaced apart parallel coloured bands the inclinations of which, to a longitudinal axis of the material, are in opposite directions on the two faces, and then cutting out strips across the individual bands by cutting in the longitudinal direction of the material, each strip forming a ribbon. In this way the colour zones of one face can be made to overlap zones of the other face in the longitudinal direction of the ribbon and each colour zone has an elongated parallelogram shape. The coloured bands can be produced by coating or printing the material, preferably with fluorescent material, on an untreated or preferably phosphorescent white background.

Title: A process of preparing improved wetting agents and detergents, and products thereof
IPC: C07C303/00
Filed: 1934-12-20
Abstract: In the production of wetting and detergent agents from products obtained by cracking paraffin wax or petrolatum and containing more than six carbon atoms by treatment with sulphating agents, the latter are used in continuous excess.  In examples: (1) 10 vols. of an olefinic fraction obtained by the destructive distillation of paraffin wax are passed in a continuous stream into a mixing chamber provided with a propeller and baffles where they meet 1 vol. of 20 per cent oleum; the time of contact of the components is 75 seconds and the resulting mixture is passed directly into aqueous caustic soda; the product is worked up into a dry soap, using isopropyl alcohol to separate inorganic salts; (2) a stream of cracked wax is brought continuously into contact with excess of oleum in a mixing chamber and after a contact of 120 seconds is passed into a second chamber where it is mixed with sufficient water to reduce the sulphuric acid to a concentration of 60 per cent; after excess acid is removed isopropylalcohol is added and the product neutralized.  By using excess of the sulphating agents, the formation of dialkylsulphates which are unstable and give rise to acid products is avoided.  Reducing the time of contact of the components and rapidly lowering the concentration of the acid after the main reaction reduces undesirable side reactions and polymerization.  The Specification as open to inspection under Sect. 91 comprises also the subject-matter of the parent Specification as open to inspection under Sect. 91.  This subject-matter does not appear in the Specification as accepted.
