Title: An improved method of and means for the purification and revivification of acid pickling liquors for iron and steel products
IPC: C23G1/36
Filed: 1946-05-09
Abstract: <PICT:0631525/III/1> Iron and steel pickling liquor is continuously purified and revivified by causing the hot liquor with suspended crystalline matter to pass up a barometric column 2 having a cooling jacket 13 at a velocity exceeding that of the descent of the ferrous sulphate crystals in the liquor, the overflow being further cooled by evaporation under high vacuum applied at 6.  The vapours evolved are condensed by sulphuric acid sprayed in at 7, the diluted acid from condenser 5 passing down leg 8 to the tank 1. The liquor in tank 1 may be at 50-70 DEG  C., and it may be necessary to cool it to 25 DEG C. on entering column 2.  Ferrous sulphate crystals entrained or formed on cooling in column 2 overflow with liquor into a conical separator 10 whence they descend the leg 17 to a conical sump 18.  An airlift 21 transfers the sludge to a separator, e.g. centrifuge 23. The cooling jacket 13 is supplied with acid overflowing from the separator 10, filtrate pumped at 26 from the separator 23 and cold water at 29.  A separate water-cooled jacket portion is, however, preferably fitted.  The column 2, the jacket 13 and the legs 8 and 17 have heights to correspond to the gravities of the liquids they hold. A degree of vacuum of 29 inches of mercury is employed.  A modification is shown wherein two columns 2 discharge into a common tank 10.

Abstract: 592,255. Sound locators. WESTERN ELECTRIC, CO., Inc. Sept. 3, 1943, No. 14456. Convention date, Feb. 19, 1942. [Class 118 (ii)] In a compressional wave radiator and receiver particularly for submarine detection systems, there is provided a number of similar electromechanical vibrator units 1a ... 14a, which may be piezo-electric crystals, magnetrostrictive or electromagnetic devices, arranged in regular formation and spaced so that the distances between the centres of adjacent units are less than one half of the shortest wavelength to be transmitted or received, in combination with a multi-section band-pass filter, comprising shunt arms 15 &c. and series arms 16 &c., having an impedance matched to that of one vibrator unit and across which the unit can be connected, the arrangement being such that the vibrator units can be driven with different phase relations for different frequencies within the pass-band of the filter so that the angular direction of effective radiation or reception of a particular frequency is dependent on that frequency, being different for each frequency within the band. In one example, each of the .fourteen units comprises nine sections 1a ... 1i, each section containing four crystals, particularly 45 degree Y-cut crystals, and the sections are backed with metal blocks. The crystals and the metal blocks are each one-quarter wavelength high so as to produce a node of motion about the mounting strip.

The effects of these arrangements are discussed with reference to various graphs. If a very wide range of frequencies is to be covered, the range is divided into a number of bands in which the difference between the lowest and highest frequencies of that band does not exceed approximately 28 per cent of its midfrequency, and a corresponding number of crystal radiators is then provided and operated in parallel.
