Title: Animal waste processing - by collecting methane gas from manure container as fuel and manure is spun and drying while steam is condensed and returned to water supply
Inventor: SCHUETZE HORST
IPC: C02F11/12
Filed: 1991-05-06
Abstract: To prepare animal waste prods. by sepn of the fluid components, the manure is held in a closed vessel (1) and forms (CH4) gas.

Title: Paper material detector - comprises opto-electrical system with control to maintain constant difference signal from subtraction unit for reliable operation even when soiled
Inventor: PAULY JUERGEN DIPL ING
IPC: G01S17/04
Filed: 1991-08-12
Abstract: The electro-optical system to detect the presence of an object against a background, with a light transmitter and receiver and light reception reference unit with a subtraction evaluation system, has an additional control unit (8). The control unit (8) acts on the signal from the light reception reference unit (3) so that the subtraction unit (4) sends a constant signal as the difference between the signals from the light receiver (3) and the reference (3) units. Pref. the control system (8) has a comparator to compare the difference signal from the subtraction unit (4) against a given value. If the difference signal falls short of the given value, it triggers a pulsed current supply to regulate the light impact on the light reception reference unit (3). A limiter at the control (8) prevents the output signal from the subtraction unit (4) being shifted so far that it can no longer register the difference between the presence or absence of the material, and activates an indicator on reaching a min. output signal. The limiter supplies a min. voltage if the output voltage from the subtraction unit (4) drops below a min. value. USE/ADVANTAGE - The system can be used in applications such as in the various drying gps. of a papermaking machine, to stop the machine if no paper is present through a web break and the like, where the wet paper/oulp mass and dry paper has to be detected against the drying components as a background. The mechanism gives a reliable detection of the presence of the material, even when the optical system becomes soiled in use.

Inventor: MAYER KLAUS-MICHAEL DR
IPC: G02B6/30
Filed: 1992-04-10
Abstract: The proposal is for a process for producing passive and/or active optical polymer components with integrated fibre chip coupling by moulding.
