Patent DE-3735296-A1 (DE)
Inventor: FILTHUTH HEINZ PROF DR
IPC: G01T1/29
Filed: 1987-10-17
Abstract: A two-dimensional proportional counter for position sensitive measurement of ionizing radiation in one plane comprises a counting chamber, in which a wire anode grid and at least one wire cathode grid are fastened spaced apart from one another and orthogonal to one another. The wires of these grids are connected directly to the windings of a continuous delay line to which the signals are fed for evaluation. The delay line has a continuous capacitor strip on its top. The dimensioning of the capacitor strip and of the other characteristic parameters of the delay line are slected such that the spacing of the grids from one another can be decreased to values below 2 mm, thus attaining a substantial increase in positional resolution, withou substantial impairment by the delay line of the form and amplitude of the pulses produced. Particularly simple and rapid measurement is attainable if a counting chamber of this design is combined with an automatic feed device for specimen plates, which in turn may also be coupled with a magazine, so that a certain number of specimen plates can be fed to the counting chamber completely automatically.

Title: Knife with constant cutting sharpness
Inventor: HORN KURT
IPC: B26D1/00
Filed: 1987-12-17
Abstract: The invention relates to a knife, especially for cutting devices used in agriculture. When the cutting edges are worn, according to the current state of the art     a) the cutting edges are resharpened or   b) the knife blades are replaced by new ones or c) the knife blades are provided peripherally with a plurality of cutting edges which come into use as previous cutting edges are worn out using the indexable insert principle.   The object of the invention is to design a corresponding knife in such a way that serviceable lives are increased without grinding or regrinding the cutting edges. This object is achieved according to the invention in that, by means of a constant knife blade thickness, which at the same time corresponds to the cutting edge thickness, the cutting edge thickness remains the same even when worn. The drawing shows the structure of the knife blade (1) and the way in which it is fastened by means of connecting elements (2) and supporting elements (3) to the basic body (4) of the knife. The basic body of the knife can be made of a relatively cost- effective flat material, as it is subjected to a smaller specific load than the knife blades. The serviceable life is derived from the amount by which the cutting edges project in relation to the front edges of the basic body of the knife. <IMAGE>

Patent DE-3901404-A1 (DE)
Title: Process for the anaerobic fermentation of organic waste products
Inventor: NEUMANN WILLI PROF DR SC TECHN
IPC: C02F3/28
Filed: 1989-01-19
Abstract: The invention relates to a process for anaerobic microbiological waste product utilisation which is suitable for converting to so-called biogas and high-grade natural fertilisers undiluted ammonia-containing aqueous dispersions and solutions containing biodegradable organic substances like waste products of agriculture such as slurries, like waste products of the food industry such as slaughtering wastes and waste products of the chemical industry. The object is achieved by the fact that after the known substrate degradation together with carboxylic acids, a self-alkalisation of the digested sludge by the anaerobic fermentation can be surprisingly exploited in order to remove ammonia from a part of the reaction medium taken out of the circulation, alone or in a mixture with substrate. The mixture can be fermented without addition of diluents so that biogas and high-grade fertilisers are formed.
