Title: Improvements in leads for sounding purposes
IPC: G01C13/00
Filed: 1928-05-19
Abstract: 291,444. Electroacustic Ges. June 2, 1927, [Convention date]. Determining distances acoustically.-A sinker for determining depths of the kind which has no line attached thereto but emits a sound or other signal when it strikes a surface, such as the bottom of the sea, comprises a paraboloidal cap 3 which has a length at least one-fifth of the total length of the sounding lead, its upper edge having a less diameter than the lower edge of the main body 1. The lead has its greatest cross-section located at a point in its lower portion between one-fifth and one-half of its total length. On striking the bottom, the cap 3 is telescoped against the pressure off a spring 5, making contact between members 8, 9 and so completing the circuit of an electric battery which has just previously been activated by the sea-water, and heating the ignition wire 14 of the detonator 10. The battery is formed by arranging porous layers of the salts of electrolytes between the main body 1, acting as one plate, and a coaxial sheet-metal cone 11, acting as the other plate. The water for activating the battery circular through holes 16, 17, 18. A safety detent 20 engaging a recess 21 in the contact members 8 presents relative movement of the cap and the main body on striking the water, and is only released when the lead has reached a depth sufficient to cause the diaphragms of an air-filled capsule 19 to yield and so remove the detent. In a modification the pressure-actuated capsule aperates a member to bridge a gap in the ignition circuit, instead of removing the detent.

Filed: 1950-06-20
Abstract: 698,805. Centrifugal compressors; gas turbine plant. BARRELL, J. June 18, 1951 [June 20, 1950], No. 15353/50. Classes 110(i) and 110(iii) A compressor comprises a rotating drum L, into which air or other gas and a liquid are simultaneously injected through a central aperture G, the air being initially compressed by impeller blades B (or coming from the final expansion stages of a closed circuit system); the mixture of liquid and air is pressurized by being flung outwardly into an annular chamber H, where separation occurs, the air flowing towards the centre by way of ducts I and part of the liquid being re-circulated through a duct J, the remainder passing through a duct K to be entrained again by air. After leaving the blades B, the air stream divides at D, and half of it is directed at E towards the central aperture G. The remainder is used to heat the compressed'air in a heat exchanger. Alternatively, it is used to entrain liquid from a container and deliver it into a conduit F. The compressed air is supplied to a gas turbine or other heat engine. In a closed circuit system, a fluorine compound as commonly used in mechanical refrigeration can be used in the gaseous phase as the working gas and in the liquid phase as the compressing liquid. Partial liquefaction may be effected in the turbine or other heat engine if the final stages are insulated by means of a vacuum jacket. Alternatively, in an open circuit system, atmospheric air is used as the working gas, with liquefied air as the compressing liquid.

Title: Improvements in the recovery of molybdenum, tungsten and vanadium from ores or the like
IPC: C22B1/08
Filed: 1931-05-26
Abstract: Molybdenum, tungsten, or vanadium are recovered from crude materials containing them as sulphides by admixture with carbonaceous materials and treatment at 250-400 DEG  C. with gases containing free oxygen, and chlorine or hydrogen chloride or both. Coal, charcoal, peat, lignite coke, pitch, tars, or heavy oils may be used as carbonaceous substances, but in the treatment of exhausted catalysts sufficient carbonaceous matter may be present. In one example, a catalyst used for destructive hydrogenation of tar, comprising sulphides of zinc, molybdenum, and magnesium and contaminated by large amounts of asphaltic and resinous substances is first subjected to low temperature carbonization and then treated in counter-current in a rotary furnace at 320 DEG  C. with chlorine containing oxygen, whereby molybdenum oxychloride is volatilized and recovered.  The residual gases are washed with water and recirculated.  In a second example, a mixture of vanadium and cobalt sulphides which has been used for the catalytic reduction of phenolic oils is mixed with an equal amount of wood carbon and treated as above described at 260 DEG C.  In a third example, waste catalysts containing sulphides of tungsten are mixed with carbonaceous substances and treated as above described at 350 DEG  C.  In a fourth example molybdenite is ground with its own weight of carbonaceous matter, and treated as abov described at 300 DEG  C.  In all cases the chlorides or oxychlorides obtained may be decomposed by water or steam to obtain the corresponding oxides.  According to the Provisional Specification oxidic materials may be treated by the process and the p chlorinating gas then be free from oxygen.

Filed: 1927-06-13
Abstract: 273,276. Wecker, E. June 23, 1926, [Convention date]. Fatty oils, purifying.-Fatty acids or mixtures containing fatty acids and fatty oils, are esterified by means of a deficiency of glycerin or other alcohol, so that all the alcohol is consumed, leaving an excess of fatty acid. The excess of fatty acid is removed from the neutral oil by means of the process of Specification 213,267, the reaction product being preferably caused to flow in a thin layer; for instance it may be heated to near the boiling point of the fatty acid, and treated with finely divided liquids such as water, toluene or alcohol at low pressure such as below 150 mm., or preferably 10-40 mm. together with superheated vapours or neutral gases. Examples describe the esterification with glycerin of a mixture of 93 per cent fatty acid and 7 per cent oil from peanuts, and of 95 per cent fatty acid of sesame oil with 5 per cent oil, the removal of the excess of fatty acid from the reaction product being effected in each case by superheated steam carrying water-mist. The process may be used in conjunction with the purification of fatty oils containing free fatty acid, the oils being first treated by a physical process such as the process described above for treating the reaction product, so as to obtain a neutral oil and a free fatty acid containing little or no fatty oil, and then treating the fatty acid product by the esterification process. The Specification as open to inspection under Sect. 91 (3) (a) includes the separation of the excess of fatty acid by a physical separation process such as treatment with a " temporarily expanding liquid mist " or by superheated vapours or gases, hydrogen being mentioned as a suitable neutral gas. This subject-matter does not appear in the Specification as accepted.
