Title: Improvements in or relating to the preparation of piperazine mono carboxamides
IPC: C07D295/215
Filed: 1947-04-02
Abstract: Piperazine mono carboxamides of the general formula <FORM:0631685/IV (b)/1> where R is hydrogen or an alkyl radical and R1 and R11 are hydrogen or alkyl radicals or may with the nitrogen atom form a heterocyclic ring, are prepared by mixing piperazine or an N-alkyl piperazine with a carbamyl chloride preferably at 0 DEG -40 DEG  C. in a solvent such as chloroform, carbon tetrachloride, ethyl acetate or water.  When an organic solvent is used the product may be recovered by saturating the reaction mixture with hydrogen chloride to precipitate any unreacted piperazine as the hydrochloride and concentrating the reaction mixture to recover the product.  When the reaction is carried out in water, in the presence of alkali, the reaction mixture may be saturated with potassium carbonate or ammonium sulphate, extracted with ether or chloroform, dried and distilled to give the product.  Compounds obtained according to the invention include those in which R is hydrogen, methyl, ethyl or isopropyl and R1 and R11 are hydrogen, methyl, ethyl, propyl, isopropyl, butyl, t.-butyl, amyl, hexyl, or NR1R11 is a morpholine, piperazine or piperidine ring.  The products are used in the treatment of filiarisis or the treatment of ascrids in dogs.  In examples, the preparation according to the invention is described of: (1), (2) and (5), 1-methyl-4-piperazine-N : N-diethyl carboxamide hydrochloride; (3) 1-methyl-4-piperazine-N : N-dimethyl carboxamide hydrochloride; (4) 1-methyl-4-piperazine-N : N-diisopropyl carboxamide hydrochloride; (6) 1-methyl-4-piperazine-N-ethyl carboxamide hydrochloride; (7) 1-isopropyl-4-piperazine-N : N-diethyl carboxamide hydrochloride; (8) 4-(1-methyl-4-piperazyl carbox) - 1 - methylpiperazide; (9) 1 - piperazine - N : N-diethyl carboxamide; and (10) 1-piperazine-N : N-dimethyl carboxamide.  Where the examples result in the formation of hydrochloride salts the free base may be formed by treatment with mild alkali.  Diisopropyl carbamyl chloride is prepared by the reaction of phosgene with diisopropyl amine. 1-Isopropyl piperazine is prepared by reacting 1-carbethoxy piperazine with isopropanol, heating with concentrated hydrochloric acid to give 1-isopropyl piperazine and reacting with alkali to form the free base.  The Specification as open to inspection under Sect. 91 comprises also the preparation of piperazine monocarboxamides in which the groups R1 and R11 may be aromatic radicals.  This subject-matter does not appear in the Specification as accepted.

Abstract: 538,154. Acetylene. BRITISH THOMSONHOUSTON CO., Ltd. May 22, 1940, No. 9083. Convention date, May 23, 1939. [Class 2 (i)] [Also in Groups XI and XII] Hydrocarbon gases such as acetylene, or hydrogen or carbon monoxide are produced by means of transient electric arcs in a liquid such as mineral oil, benzol, turpentine, oleic acid, water or sugar solution. The arcs are produced between particles 4 of coke, coal, amorphous carbon, graphite, carbides or metals, placed between graphite electrodes 2, 3, and the liquid is introduced through ducts 5 in the lower electrode. The container 1 is of iron with a lining 6 of phenolic resin and a lining 7 of alundum. The electrode stem 9 is insulated by a bush 11 of phenolic resin. The liquid passes out through strainer 13 to pump 15 and settling tank 16, and is returned through conduit 12. Carbon black may be deposited in the tank 16. Gas which is generated passes out through the pipe 20. As the current falls due to consumption of the material 4, solenoid 21 allows switch 22 to close, so that motor 25 is actuated and screw 27 feeds more material from container 28. If the liquid level falls, float 30 closes switch 33 and pump 15 is actuated to supply more liquid. The gas pressure within the container 1 may actuate a bellows 39 to open switch 38 whereby the supply circuit 18, 19 is opened. When mineral oil is used, the gases evolved consist of hydrogen and acetylene. When water is used, the gases consist of hydrogen and carbon monoxide. The voltage employed may amount to several hundred, and the current to about one ampere. Specification 454,342, [Group XXXVII], is referred to.

Filed: 1955-03-30
Abstract: 820,161. Velocity modulated tubes. ELECTRIC & MUSICAL INDUSTRIES Ltd. March 12, 1956 [March 30, 1955], No. 9214/55. Class 39(1). [Also in Group XL(b)] The cavity resonator of a klystron oscillator, amplifier or similar discharge tube is tuned by a plurality of conductive plates or vanes disposed circumferentially about the resonator which can be adjusted to different angular positions. The theory of the tuning action depends on the use of the Eo mode the circular magnetic lines of force inducing a counter magnetic field in the vanes so that the magnetic and consequently the electric fields vanish in the annular region containing the vanes. The effect is as if the resonator were smaller, i.e. without the latter annular region, so that the resonant frequency is increased and is a maximum when the vanes are radial. The magnetic lines of force are as shown at 12 when the vanes are in the latter position. The plates or vanes 7 are mounted on spindles 8 at one corner thereof so that they can be individually adjusted, e.g. by a spanner acting on the square or hexagonal heads of the spindles, each spindle passing through a ceramic bush and being locked in position by a lock nut ; alternatively they may be simultaneously adjusted by providing each spindle with gear teeth 14, Fig. 3 engaged by a toothed ring operated by a worm 16. In the latter case one vane can be adjusted independently of ring 15 for fine tuning. One of the vanes can be omitted to leave space for an input or output coupling loop. The top and bottom plates of the resonator are respectively bolted and brazed to the cylindrical part. The vanes of which there may be 16 do not contact one another or the wall of the resonator. Focusing coils (not shown) surround the resonator.
