Title: Purification of penicillin
Inventor: HASTINGS JOHN JAMES HUNTER
IPC: C07D499/00
Filed: 1953-03-07
Abstract: Penicillin is purified by treating penicillin with dibenzylethylene diamine (or a salt of penicillin with a salt of dibenzylethylene diamine) in solution in a solvent in which dibenzyl-ethylene diamine penicillin is substantially insoluble, separating the precipitated dibenzylethylene diamine penicillin and suspending it in a mixture of water and a substantially water-immiscible organic solvent, and then hydrolysing the dibenzylethylene diamine penicillin (a) under acid conditions, the liberated penicillin being recovered from the organic solvent phase, or (b) under alkaline conditions at a temperature below room temperature, the formed salt of penicillin being recovered from the aqueous phase.  It is preferred that 5 to 50 mil. water and 5 to 50 mil. organic solvent be used per gram of dibenzylethylene diamine penicillin, the water and solvent being in equal proportions. Water-immiscible organic solvents are aliphatic alcohols such as butanol and amyl alcohol; carboxylic acid esters such as butyl acetate and amyl acetate; ketones such as methyl isobutyl ketone; chlorinated aliphatic hydrocarbons such as chloroform; and ethers such as diethyl and diisopropyl ether.  Acid hydrolysis is by any mineral or organic acid at a pH of 0.5 to 1.5, and preferably 1.0. The penicillin is recovered from the organic solvent phase after a preliminary treatment with active carbon by treatment with (a) an alkaline compound of an alkali or alkali earth metal or (b) an organic base, the penicillin salt of which is insoluble in the solvent, e.g. oxycaine, procaine and dibenzylethylene diamine. Alkaline hydrolysis is preferably by means of dilute aqueous alkali such as sodium hydroxide.  Specification 716,556 is referred to.

Title: Device for producing mechanical motion by means of an electrostatic relay
IPC: H01H59/00
Filed: 1936-03-03
Abstract: 463,897. Protective cut-out arrangements ; electrically-released switches. URBANEK, O., and POGANY, T. March 3, 1936, No. 6395. [Class 38 (v)] [Also in Group X] A device for producing mechanical motion by means of an electrostatic relay comprises a movable member d normally retained from movement by a trip device h releasable by a trip lever l, which is mechanically associated with the moving electrode n of the relay so as to be actuated to release the trip device h and free the movable member d when the relay is operated by an electrical influence. When the member n is attracted about its pivot o to the fixed plate p, the weighted trip lever l, pivoted at s in a small casing g, falls and engages the tail k of the trip catch h, which disengages a pin i and allows a spring f to depress the guided rod d. The rod d may, in moving, act on a switch arm or, as shown, eject aplug y from sockets u, v, which sockets at the same time are bridged by a conducting plate e on the rod d. Restoration of the plug y lifts the rod d and by means of a wire q engaging a pin r on the lever l, raises the latter until it re-engages behind the part m on the plate n. At this point a fixed abutment t engages the wire q to deflect it and enable a subsequent operation of l to occur, when released. When applied to the protection of a wireless set against thunderstorms, con. ductor 2 may serve as the aerial and the aerial and earth terminals of the set are connected to leads 10, 11. Conductor 2 is connected at 3 to plate n and, if charged by lightning, the plate n is attracted to plate p which, with socket u, is earthed at 8. The tripping of the device ejects the plug y, Fig. 1, bridges sockets u, v, and establishes a circuit to earth from the aerial 2 over conductor 3 and members z, g, d, e, and conductor 9. When the parts are restored to the Figure 1 position, the aerial is coupled to the set by condenser 4, 5 and a switch 7, the latter being movable to a terminal 13 when an independent aerial 12 is used and conductor 2 serves merely as a lightning conductor. The rod d may in its descent alternatively close a window on the advent of a thunderstorm.

Abstract: 1,093,811. Correcting distortion in playback systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. Feb. 15, 1965 [Feb. 15, 1964], No. 6405/64. Heading G5R. Distortion produced by variations in speed of a record, e.g. a magnetic tape, is reduced by forming a signal approximately representative of the time derivative of the information signal, controlling the amplitude of this signal in accordance with the time modulation of a reference signal on the record, and adding it to the original information signal. In Fig. 1 an audio signal and an ultrasonic signal recorded on the same or on an adjacent track are separated by filters 12 and 13. The audio signal passes to a delay unit 4 and to units 2 and 3 which derive the sum and the difference of the audio signal and the delayed signal. It is shown that the difference signal is approximately equal to the time derivative of the audio signal multiplied by the delay of unit 4. The reference signal passes to a phase discriminator 17 the output of which controls the gain of an amplifier or multiplier 7 acting on the difference signal, the output of unit 7 being added to the sum output from 2 to give the final output. In a modification, Fig. 2 (not shown), the sum circuit 2 is omitted and one input of the output summing circuit 8 is taken direct from filter 12. In a further modification, Fig. 3 (not shown), the difference circuit and delay circuit 4 are replaced by a differentiating circuit 9 acting on the output of filter 12.

Abstract: 1302065 Casting composite ingots INLAND STEEL CO 11 Feb 1970 [27 Feb 1969] 6521/70 Heading B3F [Also in Division C7] Surface checking during hot rolling of machineable and extrudable steels containing Te and/or Se is reduced by filling at least most of an ingot mould with the steel free from Te and Se, allowing a skin to form at least on the sides of the ingot mould while maintaining the core molten, introducing the Te and/or Se from the top into the molten core and dispersing it therein and then allowing the core to solidify to a totally solid ingot with a skin devoid of substantial amounts of Te or Se around a core containing machinability enhancing amounts of Te and/or Se; and then hot rolling the ingot. Rimming steels are cast into an ingot mould at 1580-1593‹ C. and allowed to rim to form a solid skin. Te may be added in shot pellet or bar form downwardly into the molten core of the cast ingot, the rimming action stirring the Te into the steel. After extraction from the mould the ingot is reheated to 1100-1150‹ C. and conventionally hot-rolled to form billets. Non- rimming steels are cast into an ingot mould until the mould is 85-90% full and the cast ingot allowed to cool until a solid skin has been formed. Te is added by completing pouring with a steel jet into which is introduced Te. Alternatively, the ingot mould is completely filled with steel, allowed to cool to form an ingot skin and Te mechanically propelled into the ingot core and the ingot core stirred, by introducing gas into the ingot or mechanically.
