Patent WO-03103837-A1 (WO)
Title: Verfahren und vorrichtung zur dosierung von fluiden
Inventor: STEUDEL UWE
IPC: G01N11/10
Filed: 2003-06-02
Abstract: Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Durchführung
des Verfahrens zur Dosierung von mit Überdruck beaufschlagten Fluiden
mittels eines bistabilen, elektromagnetisch schaltenden Dosierventils mit
integriertem Sensor zur Ermittlung der rheologischen Fluideigenschaften.
Durch Abschwächung und Verstärkung entgegengesetzt gepolter Permanentmagnetfelder,
die zwei stabile Lagen innerhalb der Dosierkammer definieren, werden durch
eine elektronisch angesteuerte stromdurchflossene Spule diskrete Schaltzustände
für einen axial in einer Dosierkammer beweglichen magnetisierbaren Schaltkörper
erzeugt und bei der Bewegung des Schaltkörpers in eine stabile Lage die
Magnetfeldänderung mit einem Sensor erfasst wird. Die Auswertung der
vom Schaltkörper hervorgerufenen Magnetfeldänderung unter Beachtung
der Schaltzeiten ermöglicht Rückschlüsse auf die aktuelle
Viskosität des Fluides und damit die Möglichkeit einer genauen Dosierung
von Fluidmengen.

Title: Detector for oils in sand - using changes in electrical conductivity
Inventor: GAEUMANN ANDREAS DR PHIL
IPC: G01M3/16
Filed: 1972-07-12
Abstract: The device utilises the change in electrical conductivity of a special component which arises through swelling caused by the oils concerned.

Title: D.C. motor supply change over switch - is actuated by monostable relay through transiently increased supply voltage
Inventor: ADE WILLY
IPC: H02P7/03
Filed: 1973-07-07
Abstract: A rectifier provides the d.c. power supply for motor and controls, and a monostable relay is sensitive to voltage. At normal supply voltage this relay is not energised, and the motor supply is closed up, the direction of rotation depending on the position of a bistable relay. A sudden jump in supply voltage, by selecting reverse on the controller, energised the monostable relay. A contact changes position opening the motor circuit and connecting the thyristors in series with the mutually opposing windings of the d.c. supply. The appropriate one fires changing the position of relay contact. When the voltage drops back to normal the monostable relay drops out and its contact returns to its normal state closing the motor circuit whereupon the motor runs up in the opposite direction.
