Title: Detergent compositions
IPC: C11D1/28
Filed: 1977-04-22
Abstract: The detergent composition contains a matrix of soap, synthetic non-soapy detergent and a solvent component and also, additionally to this matrix, a water component. If the soap component is free of potassium salts, the total soap component makes up 2 to 25% by weight of the matrix, but if potassium salts are contained in it, it makes up 4 to 50% by weight of the matrix. The non-soapy detergent component (B) amounts to 5 to 88% by weight of the matrix and the solvent component (C) 10 to 70% by weight of the matrix, at least 10% by weight of the solvent component having to be water-insoluble solvents. 1 to 35 parts by weight of the water component are present per 100 parts by weight of the matrix. This detergent composition can be present in the form of a water-soluble spreadable, dimensionally stable detergent moulded article, which has a very good cleaning power and is suitable for spot removal before an actual washing process.

Title: A process for the production of filaments and films, and apparatus for carrying out such process
IPC: D01D5/088
Filed: 1962-05-07
Abstract: 977,739. Spinning apparatus. AVISUN CORPORATION. May 7, 1962 [July 24, 1961], No. 17512/62. Heading B5B. Filaments and films are made by shaping a molten polymeric material, e.g. into one or more continuous filamentary streams, passing the shaped material through a gaseous atmosphere and quenching it in a liquid bath, the gaseous atmosphere and at least the surface of the liquid bath being kept in a quiescent condition. Preferably, the quiescent gaseous atmosphere is contained and maintained under pressure, e.g. about 140 g./sq. cm. to dampen movement of the surface of that portion of the liquid quenchbath, e.g. water, adjacent to the quiescent gaseous atmosphere, suitably by the use of a hood encircling the shaped material. The length of passage of the shaped material through the quiescent gaseous atmosphere, e.g. air, may be at least 10 cms. and preferably 10-30 ems. During its passage through the quiescent gaseous atmosphere the shaped material may be stretched to reduce its size and to effect partial orientation of the polymer molecules. The quenched shaped material may also be heated and stretched. Apparatus as shown comprises a gas-tight hood 23 encircling the spinneret 19 and extending into the liquid bath 25, means (e.g. valve 45) being provided for keeping the atmosphere in the hood under pressure. Means may also be provided for longitudinally stretching the shaped material during its passage through the quiescent atmosphere (spreader bar 29, godets 31) and for heating and stretching the shaped material after it has been quenched (godets 31, 37, and heating chamber 35). The hood may be at least partially transparent, and its walls may be downwardly divergent. The method is particularly applicable to the production of polypropylene monofilaments of comparatively fine denier, the quiescent gaseous atmosphere enhancing the uniformity of the filaments despite the use of relatively small spinneret to quench bath distances.
