Abstract: Streptomycin is purified by treating an aqueous solution of streptomycin or a salt thereof with a non-acidic primary amine of general formula R-NH2 wherein R is an organic radical of 7 to 18 carbon atoms and is alkyl, substituted alkyl, aralkyl or substituted aralkyl to form an insoluble Schiff's base which is removed from the solution. The Schiff's base is hydrolysed with acid, the liberated amine removed by solvent extraction and the streptomycin, or a salt thereof, obtained from the aqueous residue. An organic solvent may be added to the aqueous solution of streptomycin to decrease the solubility of the Schiff's base or to increase the solubility of the amine in the reaction liquid. Specified solvents are methanol, ethanol, isopropanol, propanol and dioxane.  The reaction takes place at an alkaline pH especially pH 8 to 10.5 and at room temperature. Specified primary amines are lauryl, cetyl, stearyl, nonyl, 1,3-diphenylisopropyl, benzyl, dibenzylmethylamine, benzhydryl, p-chlorobenzylhydryl, betaphenethyl, p-nitrophenethyl, a -phenylpropyl, p-methylbenzyl, p-methoxybenzyl, p-methoxybenzhydryl, 3-nitro-4-methylbenzyl, beta-(naphthyl-1) ethyl and cinnamyl amines; 2-amino-1,2- diphenylethanol, N- (2-aminoethyl)- N-ethyl-m-toluidine and N-1-naphthylethylene diamine.

Abstract: 1,271,656. Fluid-pressure servomotor systems. JOSEPH LUCAS (INDUSTRIES) Ltd. June 20, 1969 [March 29, 1968], No.15171/68. Heading G3P. [Also in Division F1] In a system for controlling the fuel supply to a petrol injection piston engine, a servo-device 12 includes a piston 16 having a three-dimensional cam surface 30 thereon co-acting with a follower 31 for varying the stroke of a metering shuttle 32. The piston is angularly adjustable via arm 29, rod 26 and coupling 27, by the engine accelerator, and is axially adjustable by hydraulic pressure in accordance with engine speed. An engine-driven water-ring or centrifugal pump 11, which may supply fuel to the distributer (not shown), supplies pressurized fuel to the device 12 through a restrictor 14, the fuel thereafter passing through a variable nozzle 18 in a diaphragm 17 to an outlet 15 leading to the outlet side of a boost pump 10. Thus a change in fuel flow-rate through the nozzle 18 due to a change in engine speed, alters the pressure drop across the nozzle and thereby moves the diaphragm 17. This adjusts the degree of opening of a port 21, through which some of the fuel flows to a drain via a restrictor 23, and results in a pressure change within chamber 24 causing the piston to move to a new equilibrium position. If the pump 11 is of the water-ring type, the return line from outlet 15 may instead communicate with an intermediate pressure tapping thereof and the pump 10 may be switched off by a pressure-sensitive device when the engine speed is sufficient for the pump 11 to generate the required injection pressure.

[Class 38 (iv)] Condenser arrangements. -In a supply system in which an X-ray tube is supplied from a condenser, the tube is connected in series with an energy consumer whose resistance varies in consequence of variations in the condenser voltage, so that the voltage across the X-ray tube is maintained constant as long as the condenser voltage exceeds a predetermined value. Condensers 4, 5 charged through rectifiers 2, 3 from a transformer 1, supply an X-ray tube 6 in series with a grid-controlled valve 7 and protective inductance 10. During the discharge of the condenrers the voltage across the tube 6 is prevented from varying by supplying the grid of valve 7 from a potentiometer 11 connected across the tube 6, a bias voltage 15 and control switch 16 being provided in the grid circuit. When the condenser voltage drops below a value pre-set by the setting of the potentiometer 11, the control is no longer effective. A milliampere-second relay 19 may be arranged to operate the switch 16 so as to apply a negative blocking voltage on the grid of valve 7 to switch off the X-ray tube. If the X-ray tube current is sufficiently low, equilibrium conditions may be set up when the condenser voltage does not fall, such conditions may be used for long duration radioscopy or radiography. The rectifiers 2, 3 limit the charging current of the condensers which form a voltage doubling circuit. Specification 437,093, [Group XL], is referred to.
