Patent GB-600722-A (GB)
Title: Improvements in and relating to the preparation of salts of organic acids
IPC: C07C51/41
Filed: 1944-09-25
Abstract: A process for the production of a metal salt of an organic acid comprises heating an organic acid in the fluid state with lead, copper, cadmium, zinc, iron, nickel, silver or tin contained in a vessel having a ratio of length to greatest cross-sectional dimension of at least 10 : 1 while passing an oxygen containing gas through the vessel substantially in the direction of its length.  The process may be carried out (a) by passing the oxygen containing gas and organic acid into a converter containing in fragmentary form the metal to be treated, or (b) by passing the gas into the converter charged with the metal particles and acid in fluid form.  During both processes a portion of the fluid material may be removed from the converter and with or without removal of water returned thereto at a point remote from where it was removed.  In a modification, the reaction is effected in a solvent for the acid and salt.  The process is executed at temperatures ranging from 50 DEG  to 200 DEG  C. and at normal or superatmospheric pressures.  The acids specified are: acetic, propionic, butyric, caproic, lauric, palmitic, stearic, rincinoleic, melissic, glycollic, lactic, tartaric, oxalic, glutaric, adipic, acrylic, methacrylic, oleic, benzoic and naphthenic acids, and the acids derived from coconut, corn, cottonseed, rapeseed and similar vegetable oils.

IPC: C04B24/26
Filed: 1964-05-01
Abstract: A gypsum plaster composition comprises an aqueous stabilized dispersion of a natural or synthetic elastomer and an accelerator or retarder for the plaster in an amount which controls the setting time to give minimum cracking.  The dispersion may contain 5-30% by weight dry elastomer which may be cispolyisoprene (natural or synthetic), a styrenebutadiene copolymer, or polychloroprene; a natural rubber latex in excess of 7% by weight of the plaster necessitates the use of 0.5-20% of sodium, potassium, aluminium or ammonium sulphates or 25-100% gypsum as an accelerator for the plaster (based on the weight of plaster), and a synthetic rubber latex constituting less than 5-7% by weight of the plaster requires 0.2-5% protein, e.g. casein, or borax, as retarder, the setting time being preferably adjusted to between 20 minutes and 10 hours.  Stabilizers for the latex may be a non-ionic compound such as a polyoxyethylene ether of a phenol or a long-chain aliphatic alcohol.  Thickeners such as methyl cellulose, sodium polyacrylate, or asbestos powder may be included.  It is mentioned that the plaster may be admixed with sand, lime, whiting, or vermiculite.

Title: Improvements in and relating to the production of building boards
Inventor: CAMBRAY PHILIP GEORGE
IPC: B28B11/00
Filed: 1956-06-15
Abstract: 827,611. Severing building boards. IMPERIAL CHEMICAL INDUSTRIES Ltd. June 14, 1957 [June 15, 1956], No. 18547/56. Class 87(2). Building boards, especially gypsum plaster boards, are subjected preferably while in a wet state to a treatment such as perforating or scoring which produces zones of weakness; fed in the dry state in the direction of their length to a driven band conveyer 1 comprising one inclined intermediate and two horizontal end lengths of band 1<SP>11</SP>,  1 1 and 1<SP>111</SP> respectively through a feed roll 7 cooperating with length 11 whereby the bottom layer and at least part of the core are severed under the combined effect of the feed roll and the inclined length 111 ; caused to move forward until the weight of the part extending beyond the inclined portion and/or contact with a downwardly moving surface effects severance of the upper layer and any unsevered portion of the core ; and the severed board allowed to fall on the second horizontal length 1<SP>111</SP> of the band which carries it away. The apparatus shown in Fig. 1 comprises three similar band conveyers 1 arranged in parallel on common head and tail shafts 2, 3, idler pulleys 5, 51, 511, 4, 5111, 5<SP>1111</SP> and 6<SP>1</SP> being arranged to provide the short run 111 which is inclined at about 20 to 30 degres to the horizontal. The pulley 4 is adjustable so that it can, when the board being made is unperforated and does not need to be severed, be fixed in a lower position 4<SP>1</SP>, such that the run 111 is then horizontal, the slack of the band being taken up by movement of the shaft 3 or by moving the adjustable roller 5<SP>1</SP> downwards. By adjusting the position of the feed roll 7 the machine can be adapted to permit feeding boards of different thickness and for severing different lengths of board. The downwardly moving surface mentioned above may be provided by an auxiliary band 8 carried on rollers 9, 91, roller 9<SP>1</SP> being driven, for example by the spur gearing 10 which also drives the head shaft 2. In a modified form of apparatus the three continuous unitary bands are each replaced by three separate bands in series, the intermediate one of which is inclined when the machine is being used for severing but can be lowered into a horizontal position when not being so used. This form of apparatus operates in a similar manner to the above.

Filed: 1923-07-19
Abstract: 222,986. Norton, H. H., and Hobbs, E. E. July 19, 1923. Spray burners.-Liquid fuel sprayed by a pressure atomizer 23 in a burner casing 12 is mixed with swirling air supplied by a fan 18 arranged adjacent to the point of atomization and, in the apparatus shown in Fig. 1, then passes through a diffuser 35 consisting of concentric vanes 35<a> - - 35<e> into the furnace. A number of vanes 40 secured to the casing 12 correct the swirling movement of the outer portions of the air column. The diffuser is carried by a spider 21 on a sleeve 20 on the fuel pipe 22 and its vanes 35<a> - - 35e are stepped and inclined forwardly and outwardly, those near the atomizer being at a greater angle than those farther away. The passages between the vanes are preferably of convergent-divergent cross-section and the ribs 41 connecting the vanes are thicker at their rear ends. The fan 18 is mounted on a hollow shaft 17 rotated bv a steam-driven turbine rotor 16 arranged in a casing 13 which is secured by bolts 14 to the casing 12. The fuel pipe 22 and sleeve 20 pass through the hollow shaft 17 and are supported by a cross-head 28 secured by set screws 29 to bolts 27 on the end plate 19 of the casing 13. The sleeve 20 is adjustably secured to the fuel pipe 22 by a screw 24. Gauges 43, 44 indicate the pressure in the casing 12 and fuel pipe 22 respectively. A flexible pipe 26 leading from a pressure fuel supply is connected to the pipe 22 by a coupling 25 secured by means of a yoke 30 and a screw 32. In a modification shown in Fig. 9 the air from the fan is directed by vanes 41<a>, 41<b> on the casing 12, the vanes 41<b> imparting a whirl velocity which diminishes as the radial distance from the atomizer increases. The fuel pipe 22<a> in this construction is supported at one end by the end-plate 19 of the turbine casing and at the other end by a bearing 22b carried by bolts 22<c> to the casing 12. A clearance space between the fuel pipe and the shaft 17 is thereby afforded. Fig. 7 shows a suitable atomizer comprising a chambered block 23b and an outer member 23<a> threaded on the fuel pipe formed with a discharge orifice 34. The fuel passes to the chamber 33<c> in the block 23b through passages 33. an annular groove 33<a>, and tangential slots 33<b>.

Title: Process for the production of dl- or l-iso-propyl-aminomethyl-(3,4-dihydroxyphenyl)-carbinol and salts thereof
Filed: 1956-06-19
Abstract: DL- or L-isopropylaminomethyl-(3 : 4-dihydroxyphenyl) carbinol and salts thereof are prepared by treating DL- or L-aminomethyl-(3 : 4-dihydroxyphenyl)-carbinol with acetone and a reducing agent, e.g. hydrogen in the presence of a palladium catalyst, and if desired, isolating the resulting carbinol in the form of a salt. In place of the aminomethyl-(3 : 4-dihydroxyphenyl)-carbinol starting material there may be used corresponding compounds in which the hydroxy groups are protected by residues which may be split off by hydrogenation or hydrolysis.  Residues which can be split off by hydrolysis, for example acyl residues or methoxy groups, may be converted into hydroxy groups after the reaction, by treatment with saponifying agents.  Residues which can be split off by hydrogenolysis such as benzyl groups may undergo hydrogenolysis concurrently with the isopropylation reaction, or by suitable choice of catalysts, the two reactions may be effected separately.  The aminomethyl-(3 : 4 - dihydroxyphenyl) carbinol starting material may also be replaced by a compound such as 3 : 4-dihydroxy-o -aminoacetophenone or the corresponding 3 : 4-dimethoxy or 3 : 4-dibenzyloxy compounds which undergo reduction and isopropylation when hydrogenated in the presence of acetone and in the case of the latter compounds also can undergo subsequent removal of the methyl groups by hydrolysis or simultaneous removal of the benzyl groups by hydrogenolysis. Alternatively o -nitro-acetopyrocatechol may be hydrogenated in the presence of acetone.  The compounds may be isolated in the form of their salts with organic or inorganic acids and, in particular, the DL-compound may be treated with D-tartaric acid to precipitate the D-isopropylamino-methyl-(3 : 4 - dihydroxyphenyl) carbinol - D - bitartrate leaving the tartrate of the L-base to be crystallized from the filtrate.  In examples: (1) DL - aminomethyl - (3 : 4 - dihydroxyphenyl)-carbinol is hydrogenated in acetone on and the product is resolved by D-tartaric acid to give the D-tartrates of D- and L-isopropylaminomethyl - (3 : 4 - dihydroxyphenyl)-carbinol; (2) L-noradrenaline-bitartrate is hydrogenated in acetone to give its isopropyl derivative; (3) noradrenalone bitartrate is treated as in (2) to give simultaneous reduction and isopropylation; and (4) DL-aminomethyl-(3 : 4 - dibenzyloxyphenyl) - carbinol is hydrogenated in acetone to give simultaneous isopropylation and debenzylation.

Abstract: A process for the preparation of a monomeric phosphorous acid-alkanolamine derivative believed to have the tautomeric structures <FORM:0940697/C2/1> <FORM:0940697/C2/2> and/or the tautomeric structures <FORM:0940697/C2/3> <FORM:0940697/C2/4> where R and R1 each represents hydrogen or methyl, comprises: (1) heating a monoalkanolamine HO-CHR1-CHR-NH2 with a phosphorus compound being phosphorous acid, a phosphite ester or a salt of either of these formed from a volatile base or with a mixture of such phosphorus compounds, the reaction being carried out under such conditions that by-products liberated during the reaction are removed from the reaction phase; and (2) separating the formed monomeric phosphorous acid-alkanolamine derivative as a crystalline solid from any polyamidoalkyl phosphites produced therewith by the use of a partitioning solvent.  The amount of polyamidoalkyl phosphites produced may be minimised by reacting the alkanolamine with the phosphorus compound or compounds in substantially equimolecular proportions calculated on the total phosphorus content of said compounds in the presence of at least sufficient water and/or phosphorous acid to convert any secondary or tertiary phosphite esters to the corresponding primary phosphite esters.  When this is done, the portioning step may reduce to a simple recrystallisation. Preferred portioning solvents are the lower water-soluble primary alcohols and aqueous solutions thereof; water may also be used.  The by-products may be removed by distillation or entrainment.
