Title: Process for obtaining urea- and thiourea-derivatives of the aromatic and heterocyclic series
IPC: C07C335/04
Filed: 1930-10-23
Abstract: 1-Diethylaminoethoxy-3 : 4-diaminobenzene is prepared by treatment of 1-diethylaminoethoxy-3-nitro-4-aminobenzene with hydrogen in the presence of palladium.ALSO:Urea and thiourea derivatives containing an aminoalkyl residue are prepared by (1) converting an aromatic, hydroaromatic or heterocyclic amine having a side-chain containing an aminoalkyl residue with the corresponding urea or thiourea, or (2) introducing an aminoalkyl group into a urea or thiourea of the aromatic, hydroaromatic or heterocyclic series.  The products possess therapeutic properties.  According to the examples: (1) N-phenyl-N<1>-diethylaminoethoxyphenyl-urea is obtained by interaction of p-b -diethylaminoethoxyaniline with phenyl isocyanate; replacement of the phenyl isocyanate by phenyl mustard oil, phosgene, allyl mustard oil or potassium thiocyanate gives rise to N-phenyl-N<1>-diethylaminoethoxyphenyl-thiourea, bis-diethylaminoethoxyphenyl-urea, N-ally - N<1> - diethylaminoethoxyphenyl-thiourea and diethylaminoethoxyphenyl-thiourea respectively; (2) N-(a -pyridyl)-N<1>-(p-hydroxyphenyl)-thiourea, prepared by heating p-hydroxyphenyl mustard oil with a -aminopyridine, is treated with diethylaminochlorethane to form N-(a -pyridyl)-N<1>-(p-diethylaminoethoxyphenyl)-thiourea; (3) 1-diethylaminoethoxy-3-nitro-4-aminobenzene is reduced with hydrogen in the presence of palladium and the resulting diamine converted into 1 - diethylaminoethoxy-3 : 4 - thiobenzimidazole by treatment with potassium xanthate; (4) N-cyclohexyl-N<1>-p-hydroxyphenyl-thiourea, prepared from cyclohexylamine and p-hydroxyphenyl mustard oil, is reacted with diethylaminochlorethane to produce N-cyclohexyl-N<1>-p-diethylaminoethoxyphenylthiourea.  The process is also applicable to the preparation of ureas and thioureas containing a heterocyclic nucleus linked to nitrogen, e.g. benzimidazolylurea, and to cyclic derivatives of urea and thiourea of the type of benzimidazolone and thiobenzimidazoline.

Title: Improvements in or relating to methods of operating and lining electrolytic cells for electrolytic refining
IPC: C25C3/24
Filed: 1923-12-20
Abstract: 225,494. Aluminum Co. of America, (Assignees of Tilson, D. H.). Nov. 30, 1923, [Convention date]. Aluminium, obtaining. - A process of putting an electric cell in condition for refining a metal comprises establishing in the cell in suitable order upper and lower metallic layers 36, 34 of different densities and an intermediate layer of electrolyte 33 of intermediate density, and before the layer 36 is established freezing a crust from the electrolyte on to the sides of the cell to serve as part of a side lining 32 and after the layer 36 is established completing the formation of the lining. The cell comprises upper and lower steel shells 11, 10 insulated from one another and provided with water jackets 14, 13. The shell 10 has a carbon bottom 24 provided with a conductor 26 and resting on a layer of bauxite 23. When refining aluminium the electrodes 29 are lowered into contact with the carbon bottom and current is passed to raise the latter to red heat. The cell is then charged with an electrolyte consisting of sodium and aluminium fluorides with the addition of barium and/or strontium fluorides and current is passed therethrough. Sufficient anode alloy, consisting of aluminium, copper, and silicon is then added in a molten or solid form to raise the level of the electrolyte above the joint between the shells. The cooling action of the jackets causes the formation of a crust 32 on the sides of the cell and covering the joint. The cathode metal consisting of part aluminum is now added by pouring it slowly on the asbestos board inclined at an acute angle to the cell. The electrolyte creeps up the side of the cell by capillary attraction and solidifies thereon to complete the formation of the lining on the part surrounding the cathode.

Title: Improvements in or relating to aircraft pilot's control stick force producer and gust control

Filed: 1952-12-22
Abstract: 722,247. Controlling aircraft. NORTHROP AIRCRAFT, Inc. Dec. 22, 1952, No. 32419/52. Class 4. An aeroplane includes a control stick operating a surface by power relay, and an accelerometer responsive to acceleration in a direction normal to the surface, said accelerometer energizing a torque motor connected to the control stick in the sense to reduce excessive acceleration. As shown in Fig. 3, the output of the accelerometer 1, a variable resistance, capacity, or the like, is fed to an amplifier 2 controlling the output of a generator 3 driven by a separately excited motor 4. 'The generator 3 drives a torque motor 6 connected by a linkage 7 to the elevator-control stick 8. The control stick operates the elevator 12 through a conventional hydraulic servo-system, and is acted upon by centering springs 20. The invention supplies "feel", or, if the control stick is left free, imparts stability against gusts and the like. A rate amplifier 21 may also be connected between the accelerometer and amplifier 2, to give high stick force when the acceleration is rapidly changing, even though it be small. A trim control 23 is provided for amplifier 2, so that the torque motor may exert a permanent bias on the stick when the accelerometer gives no signal, which will displace the stick to a new neutral position determined by the strength of springs 20. The amplifier 2 may have non-linear characteristics so that the stick forces may become very large as 1.5 times the design load acceleration limit is approached.

Abstract: 521,281. Dissolved acetylene. DU PONT DE NEMOURS & CO., E. I., SCOTT, N. D., and HARRIS, C. H. Nov. 11, 1938, No. 32885. [Class 2 (i)] Solutions of acetylene are prepared by contacting acetylene or an acetylene containing gas with a liquid or dissolved organic compound having at least one carbonyl group and at least one dialkyl amino group. The preferred compound is dimethyl formamide. Other compounds mentioned include the dialkylacetamides tetralkyl ureas, tetralkyl oxamides, methyl and ethyl esters of dialkylcarbonic acids, methyl and ethyl esters of dialkyl glycine, methyl and ethyl esters of dialkyl oxamic acids, and acetonyl dialkylamines. In the case of compounds which are solid, there may be employed a solution of the coinpound in a liquid which may be either another member of the same class of compounds or a non-solvent for acetylene such as a hydrocarbon. For shipment and storage, containers are preferably filled with a porous material such as corn pith or balsa wood impregnated with the compounds of the present invention. The class of compounds used according to the present invention serve also as selective solvents for acetylene when it is present in admixture with elementary gases such as hydrogen or nitrogen. Polyacetylenes are particularly soluble in the compounds and this property may be used according to a further feature of the invention to separate a mixture of polyacetylenes, acetylene, and other hydrocarbon gases such as ethylene by first scrubbing the mixture with such a small amount of solvent that only the polyacetylehe is dissolved and then passing the scrubbed gas through a larger amount of the solvent. Acetylene is readily regenerated from solution of these solvents by heating, but polyacetylenes are regenerated by passing a current of inert gas accompanied by very moderate heating.
