Patent DE-3816081-A1 (DE)
Inventor: KNOTH JOACHIM
IPC: G01N23/223
Filed: 1988-05-11
Abstract: Said process is used for analyzing layers of said material situated near the surface by means of a total-reflection X-ray fluoro-chemical analysis process. The angle of incidence of the X-ray beam is first regulated with sufficient precision for the total-reflection condition to be fulfilled and the resulting fluorescence counting-rate relative to the angle variations to be determined through measurements. Then the angle of incidence is varied and the resulting modifications in the fluorescence counting-rate are measured by a model calculation. Thereafter, a theoretical fluorescence counting-rate varying with the different angles of incidence of the X-ray beam is established. Finally the fluorescence counting-rates for the different angles of incidence, established through measurements according to said process, are compared with the fluorescence counting-rate function calculated and established theoretically, whereby the fluorescence counting-rate established through measurements corresponding to a given effective angle of incidence of the primary radiation can be established by comparison in the total-reflection limiting area. In a second step, the optimal angle of primary radiation incidence for the desired analysis of a sample of material, corresponding to the difference from an auxiliary angle established in this manner, is regulated.

Title: Process and apparatus for obtaining fats and oils, on the one hand, and coarse meal directly suitable as animal feed, on the other hand, from soya beans
Inventor: SCHUMACHER HEINZ O
IPC: B01J8/28
Filed: 1988-08-26
Abstract: Process for obtaining vegetable oils and fats, in particular from soya beans, by extraction with organic solvents to produce an oil-containing solvent phase (MIC) and a virtually oil-free extraction residue (coarse meal; R). The coarse meal is freed of solvent, toasted and dried. The toasting is carried out before the extraction and before the so-called flocculation on smooth rollers, in combination with the thermal conditioning and adjustment of the water content of the beans, which have been only roughly broken, in particular merely halved, continuously in a system (according to P 3815726.8) which has a plurality "n" of bed units which are arranged vertically above one another and each of which is terminated at the bottom by gas-permeable plates. At the top, the raw material is heated by an air/steam mixture in conjunction with indirect floor heating to temperatures between about 60 and 90@C. The material is then brought with hot air to a temperature of about 100-120@C, and is finally dried and/or cooled in a third number of bed units with virtually dry air or an excess of air as reaction medium containing treatment gas. The material is kept in a fluidised state throughout the course of the reaction, i.e. from entry into the system until leaving it. <IMAGE>

Title: Process for starting up a device for the continuous generation of biogas
Inventor: KLEIN MICHAEL
IPC: C05F15/00
Filed: 1989-02-20
Abstract: To generate biogas, organic waste in the form of a liquid or pasty mass is rotted anaerobically with exclusion of air by the action of a mixture of bacteria from fermentative, acetogenic and methanogenic strains. Particularly during the start-up phase, not inconsiderable amounts of additives are necessary to avoid overacidification of the mixture of organic waste used and to adjust the required pH. According to the invention, to start up devices, which are sterile per se, to carry out the rotting process in a first stage a mixture of approximately four parts of aerobically rotted compost and one part of organic waste is used, the compost preventing, by temporary uptake of acids which are initially generated in excess, a reduction in the effective pH below 6.5, after methane generation has started, in a second stage the content of compost in the mixture is gradually reduced and the content of organic waste is correspondingly gradually increased to 100 % and only then is a mixture of exclusively organic waste of any desired type introduced.
