Abstract: 1. Circulatory process for concentrating and purifying sulphuric acid containing organic impurities, in which the sulphuric acid to be prepared is continuously fed to an evaporation process with the input of heat and brought to a higher concentration with continuous separation of the vapours, characterised in that the sulphuric acid to be prepared is fed to part of the acid leaving the evaporation process in concentrated form, at a distance from the point of separation of the vapours and gases from the liquid phase corresponding to the required heating path, forming a reaction line, and is led therewith to the said separation point, an oxidising agent being added in equidirectional flow to the acid to be prepared prior to its introduction into the liquid phase of the acid present in the vapourisation process.

Abstract: An apparatus for compensating the phase rotation in the feedback loop of a cartesian feedback power amplifier in a final transmitter stage for quadrature modulation of the complex difference signal between a complex input signal and the corresponding complex feedback signal with a complex modulation signal for forming a modulated real valued first signal and for quadrature modulation of the output signal from the power amplifier with a complex demodulation signal for forming the complex feedback signal. The phase shift between the first signal and the second signal and between the quadrature component of the first signal and the second signal is detected for determining the phase rotation of the feedback loop. Furthermore, the phase rotation of the complex modulation signal can be changed with a compensating phase rotation defined by the determined phase rotation.

Abstract: Blocking unit for blocking a Fallopian tube. In order to avoid local anaesthetic and difficulty when inserting such a blocking device into the Fallopian tube and, on the other hand, to ensure sufficient anchoring in the Fallopian tube, it is proposed, on the one hand, that the end of the blocking device should be widened and, on the other hand, that it should be such that said widening does not occur until after the insertion into the Fallopian tube. In other words, provision is made for retaining means, in which the widened end is accommodated in the reduced state, which retaining means are rendered inactive after insertion into the Fallopian tube. This can be achieved by, for exemple making these retaining means from a bioabsorbable material or an applicator.

Title: Process for the manufacture of alkaline-earth metal cyanamides
IPC: C01C3/16
Filed: 1951-01-15
Abstract: In the manufacture of an alkaline earth metal cyanamide, particularly calcium cyanamide from alkaline earth metal oxide or carbonate, ammonia, and solid carbon in the presence of an alkaline earth metal halide or sulphide as reaction accelerator, the amount of solid carbon present is such as is necessary stoichiometrically for the reactions MO + 2C + 2NH3 --> MCN2 + CO + H2 or MCO3 + 3C + 2NH3 --> MCN2 + 3CO + 3H2 where M is the alkaline earth metal. The carbon may be turf coke or low temperature coke, or may be produced in situ from brown or gas coal, or solid or liquid hydrocarbons.  The metal halide may be chloride or fluoride.  The ammonia may be diluted with hydrocarbons, nitrogen or hydrogen, and the reaction effected at 400 DEG -1200 DEG C.  The hydrogen from the reaction may be converted to ammonia and the carbon monoxide in the gas may be subjected to the water gas reaction to obtain further hydrogen for conversion to ammonia.  The cyanamide reaction and the ammonia synthesis may be carried out at the same pressure, e.g. 300-1,000 atm.  The reaction may also be carried out in conjunction with the conversion of calcium carbide to cyanamide by nitrogen, by passing a mixture of ammonia and nitrogen over a mixture of calcium oxide and carbide, so that the heat from the carbide reaction will supply that for the oxide reaction.

Abstract: 584.631. Snap-action switches; actuation of switches. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 11, 1945, No. 925. Convention date, Jan. 11, 1944. [Class 38 (v)] The operating mechanism of a snap-action limit switch, the contact structure and latching means of which may be similar to those disclosed in Specification 565,450, comprises a substantially cylindrical operating member 46 mounted within the switch casing and rotating with a shaft 47, an actuating member 40 pivoted at 42 for rotation between two limiting circuit-controlling positions, and a clutch arm 44 attached to the member 40 and extending into releasable clutching engagement with the member 46 so as to connect the members 40 and 46 over a predetermined range of rotation of the member 46 and to disconnect them in the case of overtravel. The member 40 actuates the latching means in the manner disclosed in the above-mentioned Specification. The arm 44 has a spring-pressed ball 45 engaging a groove 48 in the member 46, which has an integral radial arm held between the ends of a strong spring 52. A stop member 53 mounted on a partition within the casing, has two dogs 54 which are also held between the ends of the spring 52 and which hold one end of the spring when the member 46 is rotated, thereby stressing the spring. Contact 20, normally bridging contacts 18, is moved to bridge contacts 19 by counter-clockwise rotation of member 46, which movement causes member 40 to move counter - clockwise about pivot 42 through the clutching arrangement 44, 48. This movement of member 40 reverses the positions of the latch members 28, 29, 30, and causes the contacts 20 to engage contacts 19. Should the member 46 continue to rotate, the ball 45 rides out of groove 48 and the member 46 is stopped by the engagement of a shoulder 50 with the casing. Release of the handle 46 causes the parts to return to the normal position shown. This normal position may be changed by sliding stop member 53 downwards on the casing so that the member 46 is moved counter-clockwise and the position of the member 40 is reversed so that it engages the right-hand end of lever 28. The casing is ventilated through a vent in the cover.

Abstract: 523,810. Alloys. BERYLLIUM CORPORATION. Jan. 14, 1939, Nos. 1360 and 1361. Convention dates, Jan. 14, 1938, and Nov. 14, 1938. [Class 82 (i)] Alloys of beryllium, particularly with'copper, are obtained by reducing a mixture of beryllium oxide and carbon in the presence of copper, preferably finely divided, or of copper oxide with excess of carbon, in a furnace, which may be an arc or induction furnace, wherein a zone of maximum heat is produced towards the centre of the charge and is surrounded by zones of successively decreasing temperatures such that the outer portions of the charge are not above 1285‹ C., and preferably not above 850‹ C. Copper, which may be in the form of pieces, is added and melts through the charge so as to wash out the beryllium-copper alloy produced, and such copper and the reduction mixture may be charged alternately. Beryllium compounds such as hydroxide, basic carbonate, nitrate, or organic derivatives, may be used instead of the oxide, and the process may be applied to the production of alloys of beryllium with metals other than copper, which especially on reduction show a similar behaviour to copper.
