Patent GB-746327-A (GB)
Title: Processes of preparing substituted glycinamides
IPC: C07C237/00
Filed: 1954-04-08
Abstract: The invention comprises substituted glycine amides of the general formula <FORM:0746327/IV(a)/1> (wherein R1, R11 and R111 each represent an alkyl radical of not more than 3 carbon atoms, and R represents hydrogen or a hydroxy group), and their non-toxic acid-addition salts (e.g. hydrochlorides, sulphates and acetates), and the preparation thereof by heating a chloracetamide of the general formula <FORM:0746327/IV(a)/2> with a secondary amine R1R11NH, preferably in approximately equimolecular proportions in a solvent for the reactants (e.g. alcohols having 4-7 carbon atoms in the molecule, dioxan or hydrocarbon solvents) and in the presence of an acid acceptor (e.g. alkali or alkaline-earth metal carbonates, sodium bicarbonate or alkali metal alcoholates).  The products are useful therapeutically on account of their vasoconstrictor and spasmolytic action.  In examples (1) chloro-N - methyl - N - (2 - hydroxy - 1 - methyl - 2 - methyl - 2 - phenethyl) - acetamide is refluxed with diethylamine in butanol in the presence of sodium carbonate; (2) chloracetyldesoxyephedrine is similarly reacted with di-isopropylamine.  Chloracetamides of the second general formula above are obtainable by reacting together chloracetyl chloride and a secondary amine R111NH-CH(CH3)-CH(R)C6H6 (preferably in a molar ratio of 1:2) in benzene or ether as solvent, with or without heating.  It is also stated that the starting material of example (2) may be prepared from chloracetyl chloride, desoxyephedrine and pyridine.

Title: Device for producing a high intensity arc discharge
IPC: H05H1/22
Filed: 1959-03-26
Abstract: 858,734. Discharge apparatus. UNITED STATES ATOMIC ENERGY COMMISSION. March 26, 1959 [May 27, 1958], No. 10540/59. Class 39(1). A device for establishing a high-intensity direct-current carbon arc comprises a vacuum enclosure containing spaced carbon anode and cathode electrodes, means for establishing a magnetic field parallel to the axis of the discharge, means for temporarily assisting in the initiation of an arc discharge directly between said electrodes, and a variable voltage source connected between said electrodes for also assisting in the initiation and for varying the intensity of said arc discharge. Arc currents of 100 to 5000 amps may be obtained in magnetic fields of the order of 3000 gauss with a vacuum of the order of 2X10<SP>-7</SP> mm. of mercury. In the arrangement shown a cathode 1 and anode 4 of carbon are supported in brackets 2 and 5 supplied with cooling water through conduits 24 and 25 and are provided with insulated shields 6, 7 and 8. Argon is supplied to a hole in the cathode 1 through a pipe 23. Magnets 26 and 27 provide a field H axially of the vacuum chamber 9. An r.f. voltage source 13 and a variable D.C. source 15 are connected between the cathode and anode by switches 12 and 14 respectively. On closing the switches an r.f. arc appears first, followed by the main discharge. After the arc is struck the gas feed and r.f. voltage are discontinued. Vaporized carbon from both the cathode and anode absorb gas and thus produce a high pumping capacity for neutral particles. The arc will also act as an ion pump if suitable baffles are used. A further arrangement is described, Fig. 2 (not shown), in which a beam of molecular deuterium ions is passed through the arc to produce atomic ions by dissociation. The atomic ions may then be trapped to form a plasma in a thermonuclear device by the method described in Specification 853,916.

Abstract: 567,923. Automatic regulation. PARTINGTON, W., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. June 29, 1943, No. 10569. [Class 38 (iv)] The voltage on an A.C. load circuit is maintanied constant by connecting in series across the load circuit terminals 11, 12 a saturable reactor 1 and an unsaturated reactor 20, the supply source 9, 10 being connected to both circuits through a reactance 13. The saturating windings 7, 8 of the reactor 1 are connected across the reactor 20 through a rectifier 17, preferably with a swamping resistance 18, for reducing the effect of temperature changes. The purpose of the reactor 20 is the reduction or elimination of voltage changes due to variations of source frequency. A resistor having a non-linear current voltage characteristic may be included in circuit with the saturating windings 7, 8 to increase the variation of saturating current with changes in the current in the main windings 5, 6 of the reactor 1 ; this resistor may be in shunt to a part of the resistance 18 lying between the rectifier and the windings 7, 8. A damping winding 19 may be employed. A system of this character may be applied to the load circuit of an alternator, Fig. 4 (not shown), having an exciting winding fed through a rectifier from the load circuit terminals and, in parallel, through another rectifier from a current transformer in series with the load. Specification 561,289 is referred to.

Abstract: 640,748. Sheathing cables by extrusion. COMPAGNIE GENERALE D'ELECTRICITE. April 22, 1948, No. 11126. Convention date, April 23, 1947. [Class 87 (ii)] The bare cable 12 descends vertically through the sheathing head 16, and the sheathed cable continues its vertically-descending path, which is then succeeded by a curve 19 and then a vertically-ascending path to a take-up roller 20. The speed of the cable and the length of the coated cable between the sheathing head and the roller 20 is such that the sheath cools to such an extent that by the time it reaches the roller 20 it is not deformable. The path of the cable may be controlled by shifting the roller 20 horizontally, e.g. from A to B, by means of a screw device 23 operated by a chain 24. As shown, the sheathed cable descends into a well containing a cooling coil 26. The cable is pulled along by two synchronized devices 15, 27. The Specification refers to a known procedure (Fig. 1, not shown) wherein a horizontally-travelling coated cable is cooled by water sprays.

A T-spring 10 secured to the inside of the reel casing engages a square cut peripheral groove 8 in the spindle to hold the spindle against lengthwise movement in the position corresponding to retraction of the pickup. On rotating the hand crank a pin on the crown wheel pushes the T-spring out of the groove 8 and the compression spring 13 pushes the spindle rearwardly to project the pickup from the metal disc 4 to engage the line. Means may be provided for reciprocating the spool.
