Patent GB-318662-A (GB)
Abstract: 318,662. Dreyfus, H. June 7, 1928. Aliphatic acid anhydrides, particularly acetic anhydride, are produced by heating the corresponding acids in presence of aliphatic acids substituted in the alkyl group by a halogen or sulphonic group or in the hydroxyl group by residues of phosphoric acids such as mono- or poly-chlor- or brom-acetic or propionic acids, and mono- or poly -sulphacetic or acetylphosphoric acids. The reaction may be effected at 250-1000‹ C. at reduced, ordinary, or increased pressure., such as 3-10 atmospheres, in tubes &c. made of or lined with copper, silica, earthenware, fireclay &c. which may contain balls of pumice kieselguhr, carborundum &c. or catalysts known to promote the formation of the anhydride. The mixed vapours may be passed through the tube &c, or the substituted aliphatic acid may be injected into the reaction zone in liquid or vapour form. In an example a mixture of vapours of acetic and chloracetic acids containing 5-7 per cent of chloracetic acid is passed through an earthenware tube containing pumice or kieselguhr at 430-600‹ C. The anhydride may be separated from the reaction vapours by passing through the columns maintained at temperatures between the boiling points of water and the anhydride, or by passing through a solvent insoluble in water at temperatures between the boiling-points of water and the anhydride, mention being made of chlorbenzene, p-dichlorbenzene, benzylether, tetrachlorethane, paraffin oil, triacetin, phentol, anisol, one or more cresols, and p-cresy acetate. Or the reaction vapours may be condensed while carrying away The water vapour by the vapour of an entraining liquid as described in Specification 303,772, the liquids mentioned therein or toluene, xylenes, or other liquids of boiling-points between those of water and the anhydride, being used; or they may be passed under the surface of an " extracting liquid " as described in Specification 298,667; or they may be passed over a water-binding substance as described in Specification 289,972; or they may be caused to impinge up the surface of a flowing stream of benzene &c. as described in Specification 310,863. When pressure is employed, it is preferred to release the pressure before the separation of the anhydride. The initial material may be in concentrated or dilute form. Specification 280,972 also is referred to.

Title: Improvements in or relating to conveyor systems
IPC: B65G51/46
Filed: 1930-10-28
Abstract: 372,271. Pneumatic dispatch apparatus; mechanical dispatch apparatus. TELEPHON-APPARAT-FABRIK E. ZWIETUSCH & CO., GES., 6, Salzufer, Charlottenburg, Berlin. Oct. 28, 1930, No. 32400. Convention date, Nov. 12, 1929. Void [Published under Sect. 91 of the Acts]. [Class 116.] In a conveyer system in which a plurality of sections feed a main track and in which the destination of a carrier is passed forward in an associated electrical signalling system, a carrier is prevented from entering the main track until its destination designation has been recorded in the signalling system, and it enters the track in the same relative position, as regards the other carriers, as its designation holds in the signalling system. As shown in the Figure, two dispatch stations S1, S2 enter a section A2 of a track A1, A2, A3. If a carrier is placed in S1 and its designation is set up on a key-set (not shown), the carrier passes into HV1 and its position of transmission in the train of carriers is determined. When the carrier in HV1 is due to be despatched, the release of further carriers from TV or TV2 is prevented and when the carrier travelling in the section TV-TV1 operates fk1 the carrier in HV1 is released. The relative key-set restores to normal to allow a further carrier to be inserted in S1 and its designation set up. When the carrier operates fk1, the next carrier held in TV is released and when the track contacts fk2 are closed, the next carrier in either TV1 or TV2 is despatched. Contact dk3 either controls the transfer of the carrier destination indication to the apparatus at the next station or operates the releasing magnet if the carrier is to be delivered at station II. Transfer of the designations from station to station is performed by a plurality of single motion wiper switches which are taken into use in turn. The switches have two wipers one of which finds the designation of a carrier as marked from the preceding station and the other passes the marking forward. Circuit diagrams indicating the operation of the system are fully described in the Specification.

Title: A process and apparatus for the treatment of beer wort and beer or other foaming liquids
IPC: C12H1/07
Filed: 1926-12-28
Abstract: 280,395. Hansena Akt.-Ges., and Nathan, L. Dec. 28, 1926. Adding pulverulent and fibrous materials prior to filtering.-In a method of filtering beer, wort or other foaming liquid a filtering-medium is mixed with a portion of the liquid under pressure and the medium is deposited on a support such as wire-netting by forcing the mixture repeatedly therethrough, the whole of the liquid being passed under constant pressure through the filter so formed. If several layers of different media are to be superposed, the preliminary operation is repeated with the different media. Wort containing sludgy matter may be passed successively through separate filters containing a coarse and a fine media or through a filter with coarse and fine layers. Apparatus may comprise a mixing-vessel a, filter b and pump c with connecting pipes. Liquid and filtering medium being supplied to the vessel a, the pump is operated to circulate the mixture through pipes e, f, d and valve k until the mixture is uniform, after which the valve k is closed and valves n, m opened and the mixture is passed repeatedly through the filter b so that a filtering-layer is deposited therein. To prevent foaming the vessels and pipes may be initially filled with water to drive out air, the water expelled by means of carbonic acid gas, and the liquid under treatment then admitted.

Patent GB-348094-A (GB)
Title: Process for making coloured artificial textile fibres
IPC: D06P1/44
Filed: 1929-10-31
Abstract: Artificial textile fibres coloured fast to light are obtained by preparing by dispersing means, a suspension of a pigment in a solution of a product capable of being spun, the grains of pigment being made sufficiently small to be embedded in the fibre to be obtained, and then subjecting the coloured solution to the spinning operation.  The dispersion is preferably obtained by means of a colloid-mill or super-crusher.  The quantity of pigment used may be less than 10 per cent of the weight of the substance of which the fibre is made.  Organic dyestuffs fast to light such as vat dyestuffs may be used instead of mineral pigments.  In an example, viscose and powdered cadmium sulphide are mixed in a colloid-mill until the majority of the grains have a diameter smaller than one micron.  The suspension is centrifuged to remove the larger particles and is then spun and the fibre is treated in the manner usual for viscose silk. In another example, a solution of acetyl cellulose is mixed with ultramarine in a colloid-mill in a similar way to that of the previous example, and the suspension containing only particles of a diameter less than one micron is spun and the fibre treated in the manner usual for acetate silk. Instead of centrifuging the suspension prior to spinning, processes of electro-osmosis or of sedimentation may be used.
