Title: Process for the manufacture from cellulose esters of artificial products such as films, foils, plates, fibres and the like
IPC: C08B3/16
Filed: 1933-08-15
Abstract: Films, foils, plates, fibres, plastics, lacquers, and the like, are prepared from primary cellulose esters which contain both acetyl radicles and radicles derived from fatty acids containing from three to seven carbon atoms, the esters being characterized by the fact that the proportion of acid radicle other than acetyl amounts to at least 1 per cent and at most is such that the esters are not soluble in acetone, and further characterized in that they are prepared with the exclusion of catalysts such as sulphuric acid, bisulphate, and sulphuryl chloride which tend to remain behind in the cellulose molecule.  Preferably the primary ester is produced with maintenance of the fibrous structure, using catalysts such as a mixture of zinc chloride and a mineral acid, perchloric acid, a perchlorate, or methionic acid.  Examples of suitable esters are the acetobutyrate and the aceto-isovalerianate.  (1) Cotton linters are pretreated in acetic acid and esterified in a mixture of acetic anhydride, acetic acid, butyric acid, benzene, petroleum, zinc chloride, and hydrogen chloride.  The cellulose ester obtained is dissolved in methylene chloride and alcohol and used in the preparation of artificial threads or (after adding dibutyl phthalate) for casting films. (2) An ester of higher butyric acid content is obtained by increasing the amount of butyric acid and decreasing the amount of acetic acid used in the previous example.  The ester is dissolved in a mixture of methylene chloride, alcohol, and triphenylphosphate and cast into films.  (3) Cellulose aceto-isovalerianate is obtained by esterifying cotton by means of acetic anhydride and isovalerianic anhydride in the presence of benzene and one of the catalysts referred to above. The ester is dissolved in a mixture of methylene chloride and alcohol and formed into films.  A table is given contrasting various physical properties of films made according to the invention with those of films of cellulose triacetate and the commercial diacetate. Specifications 337,366, 363,700, [Class 2 (ii)], and 396,575 are referred to.  The Specification as open to inspection under Sect. 91 relates to the preparation of artificial products from cellulose esters, characterized by the use of primary mixed esters containing combined acetic acid and one or more fatty acids other than acetic acid, in which the amount of the acid components other than acetic acid amounts to at least 1 per cent of the combined acid, the upper limit of the amount of such other acids being characterized by the fact that the mixed ester is not soluble in acetone to a clear solution.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to fruit products and methods of producing the same
IPC: A23B7/026
Filed: 1933-08-17
Abstract: <PICT:0418041/III/1> A process for producing dried fruit and vegetables in powder form comprises subjecting the fruit or vegetables to an intensive crushing or disintegrating in order to reduce them to a semi-liquid pulp, passing the pulp, with added liquid if required, to a spraying apparatus of the rotary atomizer type which is arranged in the upper part of an evaporating chamber, introducing regulated amounts of heated air or gas into the upper part of the chamber, and allowing the air or gas to travel downwards with the spray through the chamber in order to evaporate the mixture from the sprayed particles.  Apparatus for carrying out the process comprises a mincing, crushing, or chopping device A from which the material passes into a pair of disintegrating mills B for reducing the semi-liquid pulp to the required state of division.  The pulp then passes into a tank C from which it is pumped by a pump D to the spraying device J through a control valve H. Water may be added if desired during or after the mincing or crushing operation, and the pump may be dispensed with, the pulp being fed to the sprayer J by gravity from a tank O.  The spraying device J, which is arranged in the upper part of the evaporating chamber L, is preferably of the type described in Specification 365,342, [Group XXIX], and it may be equipped with water-cooling means.  An air heater N, preferably heated by steam, is connected to the upper part of the chamber L by a conduit P.  The hot air entering the chamber encounters the sprayed pulp and travels with it downwards through the chamber, enabling a dried product to be collected in the lower part of the chamber whence it may be removed by a cyclone separator M or a dust bag collector. The heat generated by friction during the treatment in the crushing mills can be utilized, with additional heat from an external source if required, to obtain a pasteurized, sterilized, or cooked powder. The whole fruit or vegetable is dried, although stones, stalks, seeds, or other coarse portions may be removed before the material is introduced into the crusher A.
