IPC: B01F5/20
Filed: 1965-02-15
Abstract: Na sulphite and bisulphite spent liquors from the production of cellulose are regenerated by burning the concentrated liquors in a recovery furnace, atomizing the melt by projecting it into the apex of a cone formed of a pressurized gas, passing the atomized melt into a cooling gas at 20-150 DEG  C. to give a powder of Na2S, screening the powder into coarse and fine fractions, grinding the coarse fraction, oxidizing both fractions in a fluidized bed reactor with a gas containing O2 and steam at 50-400 DEG  C., and a p.p. of O2 of 40-150 mm. Hg, dissolving the product in water and saturating it with SO2, and passing the gases from the cooling zone and the oxidizing reactor into the furnace as combustion gases. The pressurized gas may be air or steam at 3-10 atm., and the cooling gas may be air. In atomizer 3 (Figs. 1-4, not shown), (see Division B2), the pressurized gas from feed pipe (27) is distributed in chamber (26) formed by two annular segments (23 and 24), and emerges through outlet slit (28) of adjustable size, inclined at 45-80 degrees to the plane of the circle, to form a partial conical casing of gas.  The atomizer is mounted 50-150 mm. from the end of the outlet channel 2 of furnace 1. The melt passes down channel 2 and through the central hole, and is thus forced into the apex of the cone and atomized.ALSO:Na sulphite and bisulphite spent liquors from the production of cellulose are regenerated by burning the concentrated liquors in a recovery furnace, atomising the melt by projecting it into the apex of a cone formed of a pressurised gas, passing the atomised melt into a cooling gas at 20-150 DEG C to give a powder of Na2S, screening the powder into coarse and fine fractions, grinding the coarse fraction, oxidising both fractions in a fluidised bed reactor with a gas containing O2 and steam at 50-400 DEG C, and a p.p. of O2 of 40-150 mm Hg, dissolving the product in water and saturating it with SO2, and passing the gases from the cooling zone and the oxidising reactor into the furnace as combustion gases.

Abstract: 941,434. Electric ovens. MIWAG MIKROWELLEN A.G. Feb. 25, 1960 [Feb. 25, 1959], No. 6621/60. Heading H5H. [Also in Division H1] An electric cooker includes a metallic oven enclosure provided with resistance heating elements and also fed by a source of u.h.f. power, such as a magnetron, via a waveguide which extends vertically up the centre line of one of the vertical walls of the enclosure, and one or more coupling slats in the vertical wall; a metal plate of smaller area than the latter wall is mounted inside the enclosure parallel to but spaced from the wall and with an annular gap between its edge and the other adjacent walls of the enclosure. A magnetron with cooling fins 5 is mounted between the legs (not shown) of a cooker, with a coupling probe extending into the waveguide 7, which is itself mounted against a rear vertical wall 1 of an oven, and is coupled to the latter by a slat 8 in the wall 1. The oven is also heated at the top by grill heater 3, and at the bottom by a further resistance element (not shown) mounted outside the oven, the magnetron cooling fan 10 impelling air through, successively, the cooling fins 5, the apertures 11 in the waveguide, the coupling slat 8, and the oven ventilation apertures, whereby, since the fan is wired to operate whenever either the resistance elements or the magnetron are switched on, the condensation of grease fromthe oven on the magnetron envelope is prevented. The food to be heated rests on a grid 13 of metal rods arranged parallel to the longitudinal axis of the slat 8 and mounted on one pair of a set of ridges 12 in the oven walls. Metal plate 9 is mounted in front of wall 1 to form a cavity coupling the waveguide to the oven working space, wall 1 and plate 9 being shaped as shown to reduce the sensitivity of the impedance matching to variations in the position of plate 9; the size and position of plate 9 is chosen such that the cavity resonates if no food is in the enclosure, thereby preventing damage to the magnetron by excessive reflected power. The magnetron power supply circuit disclosed in Specification 863,056 is employed.

Title: Production of salts of amino carboxylic acids
IPC: C07C/
Filed: 1965-02-16
Abstract: The partial sodium and potassium salts of nitrilotriacetic acid, ethylene diamine tetraacetic acid, diethylene triamine pentaacetic acid or variants of these acids in which there are two carboxyl groups, the remainder of the acetic acid moieties being replaced by b -hydroxyethyl groups, are made by adding to an aqueous solution of the full sodium or potassium salt of said acid, an amount of the corresponding free acid which is less than the amount calculated to give a solution of the desired salt but more than the amount calculated to give a solution of a salt in which one less acid residue is in the free acid form, boiling the resulting mixture to evaporate at least part of the water and separating off the crystals. It is preferred to add an amount of free acid sufficient to provide a greater mole percentage of the desired salt than of the salt in which one less acid residue is in the free acid form.  An example relates to the preparation of the disodium salt of ethylene diamine tetraacetic acid.

Title: Process for the production of the benzyl ester of mandelic acid
Inventor: KALGES AUGUST
IPC: C07C69/732
Filed: 1957-02-28
Abstract: Benzyl mandelate is prepared by treating an aqueous solution of alkali metal mandelates with a slight excess of hydrochloric acid, extracting the liberated mandelic acid with benzyl alcohol and heating the so obtained benzyl alcoholic solution of mandelic acid at elevated temperature.  The crude ester so obtained may be recrystallized from dilute acetic acid or methanol.  The process may be carried out by saponifying 1 mol. of dichloracetophenone with 4 mol. of caustic soda and the resulting alkaline solution acidified with hydrochloric acid until the pH is 1.  The acid solution may then be first extracted with about 5% by volume of benzene at 30-35 DEG C. using a counter current process with a suitable centrifuge, and then the mandelic acid quantitatively extracted from the solution with benzyl alcohol.  The so obtained benzyl alcoholic solution of mandelic acid is then esterified by heating at elevated temperature with azeotropic removal of the water or reaction.  Solutions prepared by the acid saponification of mandelonitrile may also be used as starting materials.  The benzyl alcohol dissolved in the aqueous phase may be recovered by treating the solution with 5% by volume of benzene and most of the benzene distilled off from the resulting mixture.  An example is given.
