Title: New imidazoline salts and a process for the production thereof
Filed: 1956-12-19
Abstract: The invention comprises 2-(3,4-dihydroxy-phenylamino) imidazoline hydrochloride and its preparation (together with that of other mineral acid salts) from a salt of an S-alkyl ether of ethylene isothiourea (2-mercapto-imidazoline) by reaction, optionally in the presence of a solvent, e.g. pyridine, at a temperature sufficient for splitting off a mercaptan (e.g. 100-150 DEG  C.) with a 4-aminopyrocatechol derivative having protected hydroxyl groups, which groups are subsequently liberated by treatment with a mineral acid.  Specified derivatives of 4-aminopyrocatechol are dialkyl ethers, bis-O-acylates and the acetone derivative.  In an example ethylene-S-methyl isothiourea hydroiodide and the acetonide of 4-aminopyrocatechol are refluxed in pyridine, when methyl mercaptan is evolved; the pyridine is removed in vacuo and residue in water added to concentrated NaOH when the acetonide of 2-(3,4-dihydroxyphenylamino) imidazoline separates; the acetonide is decomposed by standing in concentrated HCl giving the hydrochloride of 2-(3,4-dihydroxyphenyl-amino) imidazoline.

Abstract: 926,366. Preventing corrosion; generating combustion products under pressure. WESTINGHOUSE ELECTRIC CORPORATION. Nov. 14, 1960 [Jan. 12, 1960], No. 39007/60. Drawings to Specification. Class 51 (1). [Also in Group XXVI] Corrosion and incrustation of the blades of a gas turbine due to the use of vanadium-containing oil fuel is prevented by feeding a rod or tube comprising two materials into the combustion chamber at a rate controlled in accordance with the operation of the turbine. One of the materials, which may be magnesium, beryllium, calcium, barium, strontium or zinc or the oxide, sulphate, carbonate, chloride or hydroxide of one of these metals, prevents the formation of corrosive vanadates, while the other material, which may be aluminium, chromium, iron, manganese, silicon, boron, titanium, zirconium, molybdenum, or tungsten prevents the formation of an unduly thick coating on the turbine blades. The rod may comprise an alloy of the materials used, be formed as a bimetallic strip, or comprise comminuted materials bonded together by an agent such as a plastic resin. In another embodiment aluminium or other suitable metallic tubing is filled with comminuted magnesium oxide or another suitable substance. The rate of feed of the rod or tube is controlled in accordance with the temperature at the outlet of the combustion chamber and the pressure of the fuel feed by a variable speed drive motor, or the rate may be controlled in accordance with the speed of turbine shaft or air supply pressure.

Abstract: 1,039,274. Rolling. DAVY & UNITED ENGINEERING CO. Ltd. Oct. 5, 1964 [Oct. 3, 1963], No. 39009/63. Heading B3M. The work rolls 40 and 42 of a four-high mill are removable from the roll housings 10 as a unit, wheels 56 on the chocks 50 of the lower roll 42 supporting the two roll assemblies on vertically adjustable rails 57 during removal. The upper chocks 48 are situated within extensions 51 of the lower chocks, jacks 54 urging the upper roll 40 against its backing roll 18. For roll removal the backing roll 18 is raised by hydraulically actuated balance links 24 and the rails 57 are raised by jacks 60 in the lower backing roll chocks 34 until the rails cooperate with the wheels 56. The chocks 34 are themselves mounted using spacers 35 of appropriate thickness on a sled 37 which is slidable from the housings. The working roll assemblies are withdrawn from the mill on to the rails of a carriage 76, Fig. 4 (not shown), which are at the same height as the rails 57. The carriage 76 is mounted on a frame 66 which rolls on rails 70 by operating a cable 72, and is movable transversely to the rail 70 to align a replacement roll assembly with the mill. In an alternative form the rails 57 in the mill are raised by links which are attached to the balance links 24 so that raising of the backing roll 18 is automatically followed by raising of the rolls. The frame 66 and carriage 76 may be replaced by two sets of coextensive rails level with the mill rails 57 beneath which a small carriage moves to shift the roll assemblies. The roll set nearer the mill can be shifted parallel to the pass line on further rails to allow insertion of replacement roll assemblies (and is completely removable to allow the backing rolls to be replaced). A turntable may be employed in place of the movable roll set.

Abstract: 1,260,018. Continuous casting. A. ADAMEC, and R. LEDER. 5 Aug., 1969 [9 May, 1969], No. 39188/69. Heading B3F. Metals and alloys are continuously cast in a horizontal through-flow mould, withdrawal movements of the cast metal or alloy from the mould are periodically effected in a horizontal direction at a speed which is greater than the rate of solidification of the material in the mould, and relative horizontal oscillatory movements are imparted between the mould and the casting only during the periods between the above-defined withdrawal movements. The casting may also be withdrawn during the oscillations, but it must be withdrawn at a mean speed less than the mean withdrawal speed during the above-defined withdrawal movements. When casting pure metals the withdrawal speed at the beginning of each withdrawal movement is gradually increased but when casting alloys a sharp speed increase is preferable. The frequency of oscillation is 1 to 3 cycles/sec. and its maximum amplitude 2À5 mm.

Abstract: 1,107,139. Voltage tests. MAGYAR TUDOMANYOS AKADEMIA AUTOMATIZALASI KUTA#TO INT•ZET. Sept. 14, 1965, No. 39251/65. Heading G1U. A circuit arrangement for comparing the amplitudes of two voltages comprises input leads connected to a signal source 1 from which originates a first direct voltage signal which is to be measured, a pulse source 11 providing a reference signal, a transformer 2 having a primary winding 4 connected to pulse source 11 and a secondary winding 3 connected to the input leads for combining the signal to be measured with the reference signal. A second transformer 7 is coupled to transformer 2 and has a primary winding 8 for developing there-across a signal representing a combination of the two signals and a secondary winding 9 for obtaining a signal resultant from the combination and indicative of the comparative magnitudes of the two signals. When comparing the magnitudes of the two signals it is necessary to select the appropriate polarity of the pulse produced across winding 3 with respect to the polarity of the signal from source 1 so that the circuit will perform a subtracting function. Switches 5 and/or 6 are provided for preventing a signal being developed across the primary winding 8 until the reference signal is established in the circuit. The magnitudes of signals present in a plurality of isolated circuits connected to respective sources 1, Fig. 5 may be compared with the magnitude of one reference signal provided by a pulse source 11. The reference signal occurs simultaneously in the secondary windings 17, 18, 19 of a transformer 16 connected to the three isolated circuits. By sequential closing and opening of switch pairs 5 in the individual circuits, in synchronism with pulses from source 11, the individual comparisons are made and the results appear one after the other in a secondary winding 21 of a transformer 20 having a primary winding connected in each circuit. The switching means of the isolated circuits may be arranged to be sequentially switched by successive pulses or during the duration of one pulse from the pulse source 11.
