Title: Process for manufacture of building materials or the like, such as building stone, roofing tiles or slabs, wall covering plates, partition blocks and the like
IPC: C04B35/16
Filed: 1923-01-19
Abstract: 194,264. Gr÷nroos, H. March 6, 1922, [Convention date]. Stone, artificial.-Blocks, tiles, slabs, plates, &c. for building purposes are obtained by mixing. in a pulverized condition slag, glass refuse, clay, oxide of iron, saltpetre, and quartz, rendering the mixture plastic with water, moulding under pressure, and. firing at about 740‹ C. Suitable proportions of the ingredients for the manufacture of building-blocks are 400 parts by weight of slag, 100 parts of glass refuse, 100 parts of clay, 1 part of oxide of iron, 5 parts of saltpetre, and 2 parts of quartz. For paving-slabs the abovementioned proportions of slag and glass refuse are reversed. The Specification as open to inspection under Sect. 91 (3) (a) states that the slag may be replaced by other ferruginous materials, such as Java and iron ore. This subject-matter does not appear in the Specification as accepted.

Abstract: 365,781. Brakes. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London, and PICKERING, G. H., 155, London Road, Bedford. Jan. 20, 1931, No. 1896. [Class 103 (i).] Electric and magnetic; blocks and shoes acting on drums.-In a n electromechanical brake the magnetically generated thrust for separating the brake shoes and releasing the brake is taken by a loosely mounted ball 11 of steel or other durable material. The pivot point of a lever mounted on one brake shoe carrying element and coacting with the other brake shoe carrying element for separating the brake shoes, is approximately vertically above the centre of the brake drum. The brake shoe levers 3, 4 are pivoted on pins X, Y and a compression spring 6 forces the shoes 1, 2 into engagement with the drum. The lever 7 pivoted in a bifurcated part of the lever 4 carries an armature 8 of an electromagnet the field element 9 of which is mounted on the lever 4. The ball 11 is carried in a recess in the head of an adjustably screwed rod 10 carried by the lever 3 and is retained therein by a lip. The ball 11 engages a hard surface on the lever 7. When the electromagnet is energized the brake shoe levers are forced apart as far as stops 16, 17 allow and the brake is released. An adjustable stop 13 on the lever 4 engaging a lug on the lever 7 limits the movement apart of the parts 8, 9 of the electromagnet. The spring 6 is adjusted by a bolt 18. Two electromagnets may be used operating the lever 7 by means of an equalizer bar.

Abstract: Betaine and glutamic acid are obtained from molasses by the addition of one or more organic diluents, followed by or simultaneously with an acid whose salts with the cations present in the molasses are difficultly soluble or insoluble in the liquid medium, the precipitate is separated, the organic diluent evaporated, and the remaining liquid passed through one or more ion exchangers.  The first is anionic and glutamic and pyrrolidone-carboxylic acid are retained; the second is cationic and holds betaine.  Organic diluents are methyl and ethyl alcohol and acetone; whilst acids are sulphuric, sulphurous and phosphoric.  Specification 744,114 is referred to.ALSO:Molasses is diluted with one or more organic liquids miscible therewith, an acid is added, either separately or with the organic diluent, whose salts with the cations present in the molasses are difficultly soluble or insoluble in the liquid medium, the precipitate is separated, the organic diluent evaporated, and the remaining liquid passed through one or more ion exchangers.  The first exchanger is anionic and this holds the acids, whilst the second exchanger is cationic and this holds the betaine. Specified diluents are methyl alcohol, dilute ethyl alcohol and dilute acetone, whilst acids specified are sulphuric, sulphurous and phosphoric. Amounts added are-diluent, 0,6-2 kg. per kg. molasses; acid-to give a pH of 2-3,5.  The precipitate may be formed at elevated temperatures, or after formation, be heated to such temperatures e.g. 35 DEG -80 DEG C.  After precipitate removal sugar may first be recovered as described in Specification 744,114, but sugar may also be obtained from the syrup obtained from the liquid after its passage through the final exchanger.

Title: Improvements in the production of 1.3-propylene diamine
IPC: C07C209/48
Filed: 1958-01-22
Abstract: 1,3-Propylene diamine is prepared by intimately mixing acrylonitrile with 5 to 20 parts by weight of liquid ammonia for each part by weight of acrylonitrile and treating the liquid mixture with hydrogen at temperatures of from 20 DEG  to 200 DEG  C. and under a pressure of 15 to 500 atmospheres in the presence of a hydrogenation catalyst. Specified catalysts are the metals of the 5th to 8th groups and also copper and their compounds, e.g. the nitrates, carbonates, hydroxides, oxides or sulphides.  Metals mentioned are vanadium, niobium, tantalum, chromium, molybdenum, tungsten and manganese. They may be on carriers such as alumina, silicates, silica gel, zinc oxide, titanium oxide or magnesium oxide.  The catalysts are preferably pretreated with hydrogen at elevated temperature under pressure.  They may be in fixed or moving bed form or fluidized.  The mixture of liquid reactants is preferably heated to the reaction temperature or somewhat below, e.g. to 60-90 DEG  C., before passing over the catalyst.  One or both components may also be heated prior to mixing.  The hydrogen may also be preheated.  Quantities of hydrogen mentioned are 100 to 3000 litres or more per kg. of liquid initial mixture.  The process is preferably carried out continuously. The liquid reaction mixture leaving the reaction chamber is preferably immediately worked up by fractional distillation after a partial decompression during which the hydrogen together with the ammonia or a part thereof is separated from the reaction product while utilizing its heat content.  Di(o -aminopropyl)-amine is obtained as a byproduct.
