Abstract: 247,966. British Thomson-Houston Co., Ltd., (Assignees of Ennis, F. B.). Feb. 18, 1925, [Convention date]. Pneumatic conveyers.-In a conveyer in which a current of air under pressure is used for conveying light fragile articles, such as thin walled metal objects through a pipe, damage to the articles is prevented by reducing their speed by releasing a considerable volume of air just before they reach a bend or receiver. The air is released before the bend 20 through perforations 19 formed in a slightly conical part of the pipe. The outer side 16 of the bend is made of rubber, e.g. of the kind used for the inner tubes of pneumatic tyres, and the inner side 15 of metal. The articles are directed into a vertical pipe leading to one of the receivers 21 - - 23 by raising the appropriate pivoted member 25 by means of a cord 27. The bottom of each pipe opens into a chamber 30 having an inclined rubber bottom 33 and sides 31 of fine mesh wire netting through which the air escapes. The articles fall against and open a hinged door 34 closing the front of the chamber and pass on to a spiral shoot 35 in the receiver. 'When a receiver is full, one or more of the articles bridges a pair of normally separated contacts and completes the circuit of a telltale lamp. The articles are removed from the receiver through a shoot 36 controlled by a gate 37. The vertical pipe 32 leading to the last receiver has a chamber 38 at the top having sides 40 of wire netting and a front 39 of rubber which acts as a buffer for the articles. A baffle 12, Fig. 7, is provided ta prevent the air from passing up through the pipe 13 leading to the feeding hopper 11.

Patent GB-449043-A (GB)
Title: Manufacture of substances having capillary activity
Filed: 1935-02-13
Abstract: Sulphuric esters useful as wetting, levelling, washing and emulsifying agents are obtained by treating with aliphatic acylating agents which introduce carboxylic acid residues containing more than three carbon atoms, aromatic amines which contain at least one sulphonic oxyalkylamide group or sulphonic oxyalkylarylamide group or a corresponding group in which the hydroxy group is esterified with sulphuric acid.  Products which contain hydroxy groups are treated with sulphonating agents.  The aromatic amines may be prepared by causing an arylsulphonic acid amide or arylide containing a nitro group to react with an alkylenechlorhydrin, or by causing a nitrated arylsulphonic chloride to react with an oxyalkylamine or an aryloxyalkylamine and reducing the nitro group.  The products may be used in dyeing with vat and acid dyestuffs, in dyeing cellulose acetate silk, in softening artificial silk and for pasting insoluble dyestuffs. For the acylation, the esters, e.g. the glycerides, the halides and anhydrides may be used as well as the acids.  In examples: (1) 1-nitrobenzene-3-sulphonic acid anilide is treated with ethylenechlorhydrin and converted into the sulphuric ester; after reduction, the sodium salt of the amino sulphuric ester is condensed with oleic, lauric and stearic chlorides; (2) 1-nitrobenzene-3-sulphonic chloride is condensed with ethanolamine and the 1-nitro-3-benzenesulphonicoxyethylamide p  sulphonated; after reduction the product is condensed with oleic or lauric chloride; (3) 1-chlor-4-nitro-2-benzenesulphonic oxyethylamide is sulphonated, reduced and condensed with oleic chloride.  Butyric, valerianic, caproic, caprylic, capric, palmitic and ricinoleic acids are mentioned as acylating agents.ALSO:Sulphuric esters useful as emulsifying agents are obtained by treating with aliphatic acylating agents which introduce carboxylic acid residues containing more than three carbon atoms, aromatic amines which contain at least one sulphonic oxyalkylamide group or sulphonic oxyalkylarylamide group or a corresponding group in which the hydroxy group is esterified with sulphuric acid.
