Title: Process for the removal of carbon dioxide from gases
IPC: B01D53/62
Filed: 1961-10-11
Abstract: Carbon dioxide is removed from a gas, or gas mixture, by washing with an aqueous solution of a basic alkali metal compound and a neutral amino-carboxylic or -sulphonic acid the atomic ratio of alkali metal to amino-acid nitrogen being from 1 : 1.5 to 1 : 2.5, preferably 1 : 2.  Neutral amino acids are those which contain an equal number of amino and acid groups in their molecules e.g. glycine, N,N-dimethylglycine and N-methyl taurine. Potassium compounds are preferred, the hydroxide and carbonate being specified. In the example a solution of N-methyl-a -alanine and potassium oxide, in a ratio of 2 : 1, is used to absorb carbon dioxide and the amount absorbed compared with those obtained by other solutions in which the ratios vary from 1 : 0.416 to 1 : 1. The carbon dioxide may be obtained from the solution by desorption with vapour. Graphs are given comparing the absoption-desorption processes corresponding to the ratios of the example.  Absorption may be effected under pressure.

Filed: 1974-08-20
Abstract: 1464420 Insulating dynamoelectric machine windings UNELEC 20 Aug 1974 [23 Aug 1973] 36642/74 Addition to 1225546 Heading H2A In a modification of the vacuum-moulding method of insulating a rotor winding claimed in claim 1 of Specification 1,225,546, a mould is employed in which one of the constituents is a removable annular member which is not a part of the rotor, and which forms a fluid tight seal with a binding member and with a lamination clamping plate at the end of the winding remote from a current collector. In the arrangement shown, an annular member 36 is located in contact with a binding member 4 of a rotor winding 1, and with a lamination clamping plate 10 at the end of the rotor remote from a current collector 3, and the thus-formed mould is positioned vertically with the collector 3 uppermost, and a thermo-hardenable synthetic resin is poured under vacuum into the mould by way of one or more openings 39. When the resin overflows at the upper open end of the mould adjacent the collector, the pouring operation is stopped and the resin is subsequently hardened, following which the member 36 is removed. The method can be applied to rotors having copper cooling fins (31, Fig. 4, not shown) at the rotor end at which member 36 is to be located, it then being necessary to temporarily bend such fins and to apply an anti-adhesion coating before the moulding operation, and to subsequently restraighten the fins after moulding.
