Title: Mixed alkali salts of boric acid and other oxy-acids - having carbonate, phosphate-perchlorate, sulphate and selenate anions, useful as redox catalysts
Inventor: HARTL KURT DIPL CHEM DR
IPC: C01B35/14
Filed: 1979-03-26
Abstract: New mixed alkali salts (I) of boric acid and other oxyacids have an alkali metal: B molar ratio of 1.01 to 1000 and contain carbonate, phosphate-perchlorate, sulphate and contain carbonate, phosphate-perchlorate, sulphate and selenate anions. They contain (a) small amts. of 4 times O-co-ordinated B and (b) small amts. of O in the 1-oxidn. state. They are (c) paramagnetic and (d) have electron spin resonace spectra with g-values close to 2. They have (e) 2 or more phases, (f) the phase(s) present in excess acting as stabilising matrix for the phase present in small amt., whilst (g) the phase which causes properties (a) to (d) requires a very small wt. fraction. The absorption spectum of (I) pref. has a max. between 700 and 750 nm. (I) can be produced simply be tempering or fusing the components. Matrix imparts almost unlimited stability. Metastable species impart catalytic activity, esp. for redox reactions, e.g. the decomspn. of NOx to N2 and O2, the reaction of NOx and CO to N2 and CO2, the oxidn. of CO to CO2 at 400-500 degrees C, redox reactions of organic substrates, e.g. hydrocarbons, redox reaction in melts, e.g. oxidn. of cyanides with air. (I) are useful for replacing heavy catalysts where these are harmful and can be used in conjunction with inert supports.

Title: Fluidised bed dryer control - with pressure drop sensors across bed adjusting gas feed valves and nuclei feeder motor
Inventor: BERGMANN HORST DIPL ING
IPC: F26B3/08
Filed: 1979-03-29
Abstract: The control system for a fluidised bed dryer of solutions or suspensions is based on measuring the pressure drop across the perforated bottom carrying the blood. The pressure drop fluctuations are used to control the valves of the main gas inlet, of the gas branch to the classifying discharge, and of the worm feeder for the solid nuclei. This compensates for any variation of the extraneous conditions, e.g. the solids content of the solution or suspension. The stable operation of the fluidised bed results in an improved product. Used eg. for treating albumin solns.

The probe may be placed in the upper part of a housing (10) connected to the chimney, in which case the suction pipe (8) end fits into the lower part of the housing (10).
Patent DE-3031883-A1 (DE)
Title: Temperature gradient zone melting - achieves better penetration by prior application of unsaturated solution
Inventor: CHANG MIKE FUSHING
IPC: C30B13/02
Filed: 1980-08-23
Abstract: Before a melt of a high-metal semiconductor material is moved through a solid of semiconductor material by a temperature gradient zone melting process, the application of a temperature gradient to the solid is preceded by producing an unsaturarated solution of the semiconductor material in a metal layer which is deposited on the surface in a preferential planar crystal orientation. This ensures a uniform penetration of the surface by the melt when the temperature gradient is applied. The unsaturated solution contains 3-10 Si and the rest is aluminium. This method resulted in the penetration of lines of under 0.05 width and of droplets of under 0.15 mm diameter through a solid.
