Abstract: In a method for maintaining a production installation having a plurality of field devices F1, F2, F3 connected partly, or completely, over a data bus D with a control system L, the field devices F1, F2, F3 are registered in a manufacturer data base HG-DB with a manufacturer-specific identification and manufacturer-specific information relevant for maintenance, and in a customer database IB-DB with a customer-specific identification and customer-specific information. An electronic database query on the basis of maintenance criteria is performed in both of the databases HG-DB and IB-DB. In this way, both manufacturer information and customer information can be considered in the maintenance process.

Abstract: The invention relates to a method for maintaining and managing a manufacturing facility with a plurality of field devices (F) that are connected to a guide system (L) via a data bus (D). The inventive method is characterized in that information of at least the field devices that are required for the maintenance and management of the manufacturing facility are electronically acquired across the entire life cycle of the respective field device and are stored via intranet or internet access in a central data bank that is accessible for selected users. The user inquires the maintenance or management criteria via intranet or internet access to the central data bank (Z). In this manner, all information required for the maintenance and management of the manufacturing facility are made available to selected users in a simple way.

Abstract: A capacitance measuring circuit operating by the principle of switched capacitors includes a switchover device which alternately and periodically with a predetermined switchover frequency connects the measured capacitance for charging to a constant voltage and for discharging to a storage capacitor whose capacitance is large compared with the measured capacitance and whose terminal voltage is held substantially at a constant reference potential by a controlled discharge current. The magnitude of the discharge current is then proportional to the measured capacity and represents the measured value. A further switchover device applies a shield associated with the measured capacitance with the switchover frequency periodically and alternately to potentials which correspond substantially to the constant voltage and reference potential respectively. As a result, the potential of the shield is caused to follow the potential of the electrode to be shielded in accordance with the principle of "active shielding".

Abstract: A feeder for a bottle capping machine comprising a hopper to receive and direct the caps to a conveyor which transports the caps to a chute transversely disposed to the conveyor housing wherein the conveyor housing is adjustably secured to the capping machine whereby the housing can be angularly adjusted to cause bottle caps improperly oriented to fall to the bottom of the conveyor wherein the conveyor housing has an angular wiper bar to force properly oriented caps to be discharged into the chute and then feed to the capping machine, there being provided a display window and wherein the conveyor has adjustably spaced flite bars which are adapted to transport caps of various dimensions.

Abstract: A vortex flow meter for measuring the flow velocity of a fluid in a conduit includes a bluff body disposed in the flow passage of the conduit. The bluff body generates Karman vortices whose recurrence frequency is characteristic of the flow velocity to be measured. In the bluff body a cavity is formed which via passages communicates with the flow passage of the conduit and in the cavity a capacitive vortex sensor is disposed which converts the vortex pressure fluctuations originating from the Karman vortices to capacitance changes. The capacitive vortex sensor includes a first oscillating body in the form of a sensor sleeve which is deflectable by the vortex pressure fluctuations and an electrode holder which is disposed in the sensor sleeve and is formed as second oscillating body but is uncoupled from the vortex pressure fluctuations.
