Title: Process for selectively preparing mono-and di-acyl derivatives of 1-ú­-nitrophenyl-2-amino-1, 3-propanediol
Filed: 1951-09-03
Abstract: N-Monoacyl- and N : O3 diacyl derivatives of 1 - p - nitrophenyl - 2 - amino - 1 : 3 - propanediols (in which the acryl groups are of the type R.CO-, where R is an alkyl or haloalkyl radical) are manufactured by treating a 1-p-nitrophenyl-2-amino-1 : 3-propanediol with the chloride of the appropriate carboxylic acid dissolved in the corresponding acid, saturated with hydrochloric acid, and bringing the resulting O : O-diacylated aminodiol hydrochloride to a pH above 7 to cause migration of an acyl group to the nitrogen atom with or without simultaneous saponification of the other o-acyl group. Alternatively a 1-p-nitrophenyl-2-amino - 1 : 3 - propanediol hydrochloride is employed as starting material, in which case the free hydrochloric acid may be omitted in the acylation step, which in either case is preferably effected at a temperature below 40 DEG  C. The adjustment of the pH is preferably effected by alkalization after addition of water, and may be carried to a point between 7 and 8, to produce the N : O3-diacyl derivative, or to above 8 at 0-30 DEG  C. after dilution of the aqueous mixture with an organic solvent miscible therewith, to yield the N-monoacyl derivative.  In examples (1) threo - 1 - p - nitrophenyl - 2 - amino - 1 : 3-propanediol is treated with acetyl chloride in glacial acetic acid saturated with hydrochloric acid, and ether is added to isolate threo-1-p-nitrophenyl - 1 : 3 - diacetoxy - 2 - aminopropane hydrochloride, which is dissolved in water and treated with sodium bicarbonate to form threo - 1 - p - nitrophenyl - 2 - acetylamino - 3-acetoxypropan - 1 - ol; (2) erythro - 1 - p-nitrophenyl - 2 - amino - 1 : 3 - propanediol hydrochloride is acetylated as in (1), and the erythro - 1 - p - nitrophenyl - 1 : 3 - diacetoxy-2-aminopropane hydrochloride which separates is dissolved in water and acetone and treated with caustic soda to give erythro-1-p-nitrophenyl - 2 - acetylamino - 1 : 3 - propanediol; (3) L - (+) - threo - 1 - p - nitrophenyl - 2-amino - 1 : 3 - propanediol is treated as in (1) (but omitting the addition of ether at the end of the acylation), producing L-(-)-threo-1-p-nitrophenyl - 2 - acetylamino - 3 - acetoxypropan - 1 - ol; (4) D - (-) - threo - 1 - p - nitrophenyl - 2 - amino - 1 : 3 - propanediol hydrochloride is treated with dichloroacetyl chloride in dichloroacetic acid, after which ice and acetone are added followed by caustic soda to produce chloramphenicol.

Patent GB-822000-A (GB)
Title: Improvements in or relating to spark gap apparatus
Inventor: BROOKS NORMAN COLSTON
IPC: H01T2/02
Filed: 1958-06-30
Abstract: 822,000. Spark apparatus. STANDARD TELEPHONES & CABLES Ltd. June 30, 1958, No. 20832/58. Class 39(1). Spark gap apparatus comprises spaced main electrodes having concentric opposed surfaces, a single stationary trigger electrode insulatingly disposed within one only of said main electrodes and having its tip standing in a central aperture in said main electrode, the trigger electrode being adapted to fire the main spark gap by causing a field distortion in said main spark gap, and a pot magnet concentric with said electrode array for creating a radial magnetic field in said main spark gap. In the arrangement shown the pot magnet has an outer annular pole 24 attached to a cylindrical insulator 25, and an inner annular pole 26 to which a main electrode 27 is attached. The electrode 27 is connected by a strap 28 to a terminal 29 which passes through an insulating bush 30 to an earth connection 31, so that during operation the discharge current is prevented from passing through the pole 26. The magnet is energized by a winding 32 having two d.c. connections, one of which is shown at 33. The trigger electrode 34 is carried by an insulating member 36 which is surrounded by a metal sleeve 37 forming an electrostatic screen. The form of the member 36 is such as to encourage local corona discharges which assist the trigger effect. The other main electrode 39 is carried by a rod 40 threaded into a metal end cap 41 carrying an H.T. terminal 42. Air under pressure from an inlet 44 enters the enclosure through a channel 45 in the vicinity of the trigger electrode 34 and is discharged through a restrictor valve 46. Owing to the shape of the electrodes 27 and 39, a discharge originating near the axis will move radially outwards very rapidly so as to flow across the shortest possible gap, and is then rotated by the magnetic field, thus reducing erosion of the electrodes. In a simplified arrangement, Fig. 3 (now shown), a permanent pot magnet is used and the electrodes are not enclosed.
Patent GB-701179-A (GB)
Title: An improved method of manufacturing 3-picoline
Filed: 1951-09-04
Abstract: 3-Picoline is separated from a mixture of pyridine bases contained in basic tar fractions boiling at 140-145 DEG C., by treating with cupric or cuprous chloride or with cupric chloride and a reducing agent such as sulphur dioxide or alkali metal sulphates whereupon the 3-picoline forms a crystalline precipitate of a copper complex from which the free base is obtained by steam distilling in the presence of an alkali such as sodium hydroxide. The cupric chloride may suitably be added as an aqueous solution. In a modification suitable for the purification of high percentage 3-picoline the crude base is added dropwise to solid cuprous chloride, the reaction mixture is heated until the cuprous chloride is dissolved and the crystalline precipitate produced by cooling is separated and decomposed.  In examples (1) a mixture of pyridine bases is treated with aqueous cupric chloride and boiled and the copper complex which separates on cooling is decomposed by steam-distilling with aqueous alkali to give 3-picoline; (2) pyridine bases are separated as in (1) using cupric chloride and sulphur dioxide and (3) 95 per cent. pure 3-picoline is added to solid cuprous chloride and heated to dissolve the cuprous chloride and the precipitate which separates on cooling is decomposed to give 3-picoline.
