Patent DE-4109740-A1 (DE)
Inventor: BLERSCH ARTHUR
IPC: F16D65/14
Filed: 1991-03-25
Abstract: The invention concerns an electromagnetically operated spring-pressure brake or coupling (1) which operates on the closed-circuit current principle. In the no-current state of a coil (8), a closing force is exerted on a disc armature (15).

Patent DE-4131296-A1 (DE)
Inventor: HALFTER GEORG DR
IPC: C05C3/00
Filed: 1991-09-20
Abstract: The invention concerns a method of processing animal excrement and liquid manure (fluid-solid materials) in order to utilize the ammonia in the material in non-volatile, chemically bound form as fertilizer, and the disposal by combustion of the polluting constituents of the material which are not easy to react chemically, or residues arising from the process, such as residual ammonia, methane gas or strong-smelling gaseous substances such as skatoles and mercaptans. The method is characterized in that the non-bonded and/or dissolved ammonia in the material is converted, by the addition of carbon dioxide and gypsum, into a non-volatile nitrogenous fertilizer which is readily absorbed by plants. Exhaust air from animal-husbandry facilities is preferably used as the source of carbon dioxide. Strong-smelling substances, residual ammonia and methane and other volatile substances from the exhaust air are removed from the material usually in a stripping procedure by passing oxygen, preferably in the form of air, and in particular exhaust air from animal-husbandry facilities, into the material. Such substances are combusted over a thermal catalyst, or in combustible gas, when they leave the installation.

Patent DE-4203099-A1 (DE)
Inventor: DENZ HELMUT DIPL ING
IPC: G01F23/18
Filed: 1992-02-04
Abstract: A device for detecting the fuel level in a motor vehicle tank is distinguished by the following functional groups: a tank seal checking device (24.1, 32); a gas detector (22, 23) to check whether the fuel in the tank is gassing; a pumping/cycle control device (10) to subject the tank to a change cycle; a gradient evaluation device (24.2, 31) to evaluate the value of a pressure change gradient from at least one pressure change and an appropriate period of time; and level indicator (34, 35) which receives the signals from the tank seal checking device, the gas detector and the gradient detection device in order to indicate the current level with the aid of a known relationship between the pressure change gradient and the level when the tank is properly sealed and the fuel gassing rate is sufficiently low. This device makes it possible to implement a process which is not dependent on the signal from a level sensor for detecting the level in the tank and in which said signal accordingly does not have to be taken via special lines to a control device and digitised therein. Rather, pressure signals are used in a form received by the control device for the direct performance of a reliable checking of the efficiency of a ventilation system working with the tank.
