Title: Process for the manufacture of water-soluble diazoimino compounds
IPC: C07D209/08
Filed: 1933-10-31
Abstract: Water soluble diazoamino compounds are made by causing a diazotized aromatic amine free from groups inducing solubility in water to react in the presence of an acid-binding agent on a secondary amine not capable of azo dyestuff formation in which the NH-group forms part of a ring system and which cyclic imine contains at least one sulphonic acid and/or carboxylic acid group with the exception of the compounds specified in Specification 407,840.  They are useful in the manufacture of azodyestuffs and in dyeing or printing.  In examples diazoimino compounds from the following are described: (1) diazotized 2 - chloro - 4 - benzoylamino - 5 - methoxyaniline and 2 : 2 : 4 : 6 - tetramethyl - 1 : 2 : 3 :-4-tetrahydroquinoline sulphonic acid; (2) diazotized m-chloraniline and 2-methyl-2 : 3-dihydroindole sulphonic acid; (3) diazotized 4-chlor-2-anisidine and carbazole-2-sulphonic acid; (4) diazotized 4-chloro-2-toluidine and hexahydrocarbazole sulphonic acid.  2-2 : 4 : 6 - Tetramethyl - 1 : 2 : 3 : 4 - tetrahydroquinoline sulphonic acid is made by dihydrogenating 2 : 2 : 4 : 6 - tetramethyl - 1 - 2-dihydroquinoline with tin and alcoholic hydrochloric acid and sulphonating.  2 - Methyl - 2 : 3 - dihydroindole sulphonic acid and hexahydrocarbazole sulphonic acid are obtained by sulphonation of the corresponding base. p   The Specification as open to inspection under Sect. 91 comprises the following examples: (1) The diazoimino compound from diazotized m-chloraniline and 2-methyl-2 : 3-dihydroindole sulphonic acid is made into a printing paste with the o-toluidide of 2 : 3-oxynaphthoic acid and cotton printed therewith is steamed and the colour developed in an acetic acid, formic acid and Glauber's salt bath; (2) the diazoimino compound from diazotized 4-chloro-2-toluidine and hexahydro-carbazole sulphonic acid and diacetoacetyl - o - toluidine are used as above; (3) dry mixtures comprising the above components are described; (4) a solution of the o-toluidide of 2 : 3-oxynaphthoic acid and the diazoimino compound from diazotized 4-chloro-2-toluidine and hexahydrocarbazole sulphonic acid is treated with acetic acid to precipitate the dyestuff; (5) cotton is impregnated with the o-toluidide of 2 : 3-oxynaphthoic acid and treated with a solution obtained by adding acetic acid to the diazoimino compound from diazotized m-chloraniline and a -methyldihydroindole sulphonic acid.  Diazoimino compounds from 6-substituted tetrahydroquinoline-8-sulphonic acid are specified.  It is also stated that tetrahydroquinoline-8-sulphonic acid couples in the 6-position with diazo compounds to form azo dyes.  This subject-matter does not appear in the Specification as accepted.

Title: Gaseous reduction of pelletized iron ores
IPC: C21B13/02
Filed: 1965-07-16
Abstract: Pelletized iron ores, particularly taconite ore beneficiated by magnetic separation, are reduced with a gaseous mixture of CO and H2 in a reduction zone of a shaft furnace whereby CO2 and H2O are produced in the gaseous mixture which is regenerated by withdrawing the top gases and cooling them to abstract water while allowing CO2 to remain, enriching them with CH4, passing the enriched gases through a heating zone, e.g. selectively through a plurality of stoves, at 2000-3000 DEG F. to produce CO and H2, moderating the temperature of the gases to between 1300 and 1800 DEG F. e.g. by mixing therewith a portion of cooled top gases and returning the gases to the reduction zone. The reduced pellets are preferably passed from the reduction zone into an adjacent cooling zone into which cooled top gases are introduced together with a portion of CH4.

Filed: 1932-10-28
Abstract: 409,739. Rotary pumps. SCHREIBER, F. E. E. G., 24, Lowndes Square, Belgrave Square, London. Oct. 28, 1932, No. 30336. [Class 110 (ii).] The compressor comprises outer and inner rotors D, Z, coupled together as by external gearing v<1>-v<4>, in which blades B extend axially from a disc A and co-operate with recesses z to form pumping chambers. Pressure behind an abutment block K and in recess w is equalized through the inter-connection of ports m, n. A throttle device T may be provided in this byepass. The casing D is recessed at the top to permit close co-operation with the seal Z over the arc x, y. A second driving means for the seal comprises rollers on pins which are supported at each end in the disc A and in blades B. These rollers engage with grooves in the recesses z and in a groove on the outside of abutment K. The rollers may be mounted on flexible supports. In a modification, the disc A acts as a partition between two pumping chambers displaced axially. Gearing may be incorporated between the impeller shaft and a power shaft. A number of compressors may be arranged axially in alignment. A further arrangement is shown in Figs. 11, 12 in which the block K has an extension P.

Title: Improvements in or relating to projectile fuzes
IPC: F42C1/00
Filed: 1938-10-20
Abstract: 524,860. Ammunition fuzes. SKODA WORKS, PLZEN, and PANTOFLICEK, B. Oct. 20, 1938, No. 30385. Convention date, Oct. 20, 1937. [Class 9 (i)] A projectile fuze in which communication between the priming and delay charges is opened by a valve member tc ignite the delay charge upon impact with the target, is characterized in that the gases from the delay charge escape through or past the valve member so long as the projectile is subjected to retardation, the communication being closed as soon as the retardation ceases, such closure of communication causing a sudden increase of pressure of the combustion gases to disrupt the delay charge and thus ignite the detonator. The valve member may be in the form of a freely-mounted or spring- loaded ball, cylinder, or plate member. Fig. 1 shows a construction in which a ball 4 seated on a ring 5 and loaded by a spring 6 is provided between the primer and the delay charge 3. Upon impact of the projectile, the ball 4 moves forward against the spring 6 into contact with short ribs 17, thus allowing the gases from the primer to ignite the delay charge 3. When retardation ceases, the ball 4 is returned to its seating by the spring 6 and the gases from the delay charge, and the gas pressure due to the latter then increases in the space between the delay charge and ball, until the delay charge is disrupted and the detonator ignited. In a modification, the spring 6 may be omitted and the ball 4 may be pressed against the ribs 17 by a layer of compressed powder which is ignited by the priming charge to free the ball. In other modifications, the ball 4 is replaced by a cylindrical member or a perforated circular plate. Fig. 14 shows a fuze in which 50 is the priming charge, 33 the valve member, 3 the delay charge, 41, 42 the detonator and 32 a layer of lightly compressed powder which initially holds the valve 33 away from its seat 27.
