Patent GB-728437-A (GB)
Title: Choline salts of ª-methyl-mercapto-ª-acyl-aminobutyric acids
Filed: 1951-07-04
Abstract: The invention comprises as new compounds the choline salts of g -methyl-mercapto-a -acylamino butyric acids (N-acylmethionines) wherein acyl is the radical of a carboxylic acid.  The compounds may be obtained by reacting a g -methyl-mercapto-a -acylamino butyric acid with equimolar quantities of choline or by reacting a metal salt of g -methyl-mercapto-a -acylaminobutyric acid with equimolar quantities of a mineral acid choline salt in the presence of a suitable solvent or diluent.  Instead of a metal salt there may be used substances forming such salt, e.g. N-acyl-methionine and alkali metal hydroxide or alkali metal alcoholate.  In an example, alcoholic sodium ethylate is introduced into a solution of choline chloride in absolute alcohol with cooling, the precipitated sodium chloride is separated out and the alcoholic solution of choline base is added to a solution of N-acetyl methionine in water to give a solution of neutral reaction which is evaporated in vacuum to remove the water and alcohol and leave the choline salt of N-acetyl methionine. Aqueous solutions of the salts may be used for injection purposes (see Group VI).ALSO:Aqueous solutions of choline salts of N-acylmethionines in which acyl is the group of a carboxylic acid (see Group IV (b)), are stated to react neutrally and may be used for injection purposes.  An example describes the preparation of the choline salt of N-acetyl-methionine, the salt being obtained in the form of a neutral solution in aqueous alcohol from which it is recovered as a syrupy mass.

Title: Improvements in and relating to electric current converting arrangements, particularly for high voltage rectification
IPC: H02M7/40
Filed: 1934-05-28
Abstract: 442,280. Converting. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. May 28, 1934, No. 15884. Convention date, May 27, 1933. [Class 38 (ii)] In a polyphase converter comprising electric discharge devices A, B in association with a synchronously operated switch S arranged to relieve the discharge paths of reverse voltage during their nonconducting periods, means are provided to advance the moment at which commutation is completed in order to reduce the amount of reverse voltage present at the discharge path from which current is being transferred prior to opening of the switch contacts associated with that discharge path. In one arrangement, a condenser 4 is inductively coupled through a winding 20 with windings 11 ... 16 in series with the discharge paths in order to expedite commutation by neutralizing the leakage reactance of the main transformer 3. Alternatively, condensers may be connected directly in series with the discharge paths. In another arrangement, Fig. 2 (not shown), commutating voltages are introduced through a transformer connected between the neutrals of the two groups of main transformer windings, these voltages causing the voltage on the discharge path from which current is being transferred to fall more steeply, or the voltage on the discharge path to which current is being transferred to rise more steeply. The discharge devices may have a mercury vapour or other gaseous filling or they may be air spark gaps. The Specification as open to inspection under Sect. 91 comprises also arrangements in which discharge devices having suppressor grids are employed, and arrangements in which a number of discharge devices are connected in parallel to shorten the commutation period for a given load current. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to drifting valves for locomotives
IPC: F01B25/00
Filed: 1926-06-25
Abstract: 257,577. Hanlon, J. H.. and Hanlon, W. J. Aug. 28, 1925, [Convention date]. Anti-vacuum apparatus, and apparatus for running without steam.-Comprises a fluid-pressure operated drifting valve for admitting saturated steam to the locomotive cylinders either for running without steam or for warming, up when starting. Saturated steam is supplied from the boiler through a pipe 16 to the drifting. valve 24, and, when the valve is open, passes through a pipe 17 to the cylinder valve chests 12. The valve is closed by the boiler pressure, and is opened by means of a plunger 29 actuated through a lever 37 by a piston 39 working in an air cylinder 21. Air is supplied from the air. brake pipe. 14 through a hand-controlled valve 43 and a pipe 44 to the cylinder 21 to act on the piston 39 and so open the drifting valve. An auxiliary valve 31 extends through the stem of the drifting valve and its lower end is acted upon by the plunger 29 so that this valve is first opened and the main valve is then easier to open. When the air supply to the cylinder 21 is cut off .a, spring 34 withdraws the plunger 29 and the drifting valve seats itself. At the same time a valve 32 on the plunger 29 closes the lower part of the valve casing 20 and protects the gland 28 from superheated steam coming from the cylinders through the pipe 17. A whistle 45 situated between the air valves 43 and the cylinder 21 reminds the engine driver that there is pressure in the cylinder 21 and that the drifting valve is open, and when the air valve is closed the whistle allows the air to escape from the cylinder 21 so that the valve 24 closes. Both faces of the piston 39 and the corresponding cylinder ends are ground to make air-tight joints and avoid the necessity for packing. An air passage 48 is formed in the stem 40 of the piston to put the lower end of the cylinder into communication with the atmosphere, after the piston has moved a certain distance.
