A field device for monitoring an operating state of an electrical engineering installation, in particular a transformer substation or a switching substation, having an evaluation device, which evaluates input signals, which are present on the input side and relate to the electrical engineering installation, on the basis of predetermined criteria and, on the output side, generates an output signal, which characterizes the respective evaluation result. An identification can be input to the evaluat...

An article bearing a flow field such as a distribution plate for use in a fuel cell is provided. The active portion of the article, i.e., the portion of the article bearing the flow field, comprises at least two subsections; a first central subsection and a second peripheral subsection; wherein channels within the first subsection have a cross-sectional profile that differs from that of channels within the second subsection. Typically, channels of the first subsection have lesser depth, greater ...

A portable, foldable camp or field seat, which may be folded to a size which can fit into a standard rear pocket. A base plate, having a footprint resistant to sinking in loose soil has, pivotally affixed, spaced apart wire frame seat supports which rise at an outward angle to support a cloth seat. The cloth seat is attached around the upper ends of the two foldable wire frame supports, forming the front and rear of the seat. The seat is used like a small saddle, sitting in a fore and aft direct...

A field marker for easily and compactly folding to and from an implement with relatively few moving components. The inventive device includes an inner arm pivotally attached to a bracket structure attachable to a side of an implement, an outer arm pivotally attached to the inner arm, a marking disc journaled to a distal end of the outer arm, a first hydraulic cylinder attached between the bracket structure and the inner arm, a second hydraulic cylinder attached between the inner arm and the oute...

A field memory having a distributed architecture is disclosed and in particular a memory arranged in block, wherein each block stores a bit or bits of said word, said bits having a predetermined position within said word. The distributed architecture improves the transfer of data between the input/output buffers and the internal registers of the memory. A data cache and an improved input erasable realisation are also disclosed.

A field anchor consisting of an anchor post, a horizontal tow bar attached to the post midway between its ends and a diagonally positioned compression brace extends between the uppermost end of the anchor post and the tow bar whereby movement imparted the horizontal tow bar will pull the anchor post into the ground in a field or the like to provide an anchor such as useful in attaching a cable and winch to pull a vehicle toward the anchor.

There is provided a field emitter capable of efficiently maintaining the temperature of an emission point at a constant temperature. Electrons are supplied to the emission point for emitting electrons, through both two routes which are composed of a first cathode in contact with a first cathode base conductor, and a second cathode, respectively. The first cathode and the second cathode are contacted at the emission point. The first cathode and the second cathode are insulated from each other by ...

The method of forming a field joint around the bare joint of two joined insulation covered pipes includes providing a first angular cut back in the coating to expose the end of a pipe and providing a second cut back in the coating to provide an annular band of the coating of a lesser diameter than the coating on the pipe. A thin coating of polyurethane may then be applied over the first and second cut backs and a recess provided in the band of coating. A mould may then be secured around the less...

Methods and devices for producing inhomogeneous electrical fields are disclosed.

Chemical compounds of the formula ##STR1## as well as pharmaceutical compositions containing them and methods for their use in the treatment of disorders and diseases responsive to modulation of the GABA.sub.A receptor complex of the central nervous system, such disorders and diseases including anxiety, sleep disorders, anesthesia, memory disorders, and epilepsy and other convulsive disorders.
