    摘要: A needle safety guard device adapted to attach to a liquid container is provided. The device includes a disk-shaped shield having a medial opening connected with a radial opening between two radial edges. The device also includes a substantially U-shaped holder having two sidewalls coupled substantially perpendicular to the disk-shaped shield along the two radial edges, and a top cover connecting to the two sidewalls and extending from the shield above the radial opening. The U-shaped holder includes a wedged protrusion and a curved protrusion extending from each of the two sidewalls, the curved protrusion being between the top cover and the wedged protrusion for blocking a cap of the liquid container from moving toward the medial opening.

    摘要: A highly dynamic piezo-electric drive mechanism for use wherever stringent requirements are placed on resonant frequency, positioning time, actuation speed or acceleration, is provided and in which at least two piezo-electric double stack drives are rigidly mounted on their first base surfaces and act against a toggle lever on their second base surface on opposite sides of and equidistant from the pivot axis of the toggle lever, and a control applies a phased electrical voltage to the piezo-electric stacks in such manner that the double stack drives operate in a push-pull mode.

    摘要: A power supply arrangement which is intended, in particular, for intrinsically safe electro-hydraulic control systems for mining and comparable applications, in which several control units and loads controlled thereby are supplied as a group from a common constant voltage source. The voltage source has a current capacity which is smaller than the total current requirement of all the units and loads supplied by it. Each control unit has actual value current measuring device and two controllable current sources which are connected to a common potential line which can simultanously act as a data bus. The arrangement enables the respective effective dynamic current consumption and demands of the control units and loads to be ascertained to enable the available power of the constant voltage source to be determined at any time at the individual control units. The available power of the source can be utilised for an optionally time-staggered ordered control process according to predetermined priorities without overloading the voltage source.

    摘要: Production of tertiary methylphosphine oxides of the general formula ##STR1## in which R and R' each stand for identical or different, branched or unbranched, substituted or unsubstituted alkyl, cycloalkyl, aralkyl or aryl groups having from 1 to 18 carbon atoms. The compounds are produced by subjecting tertiary hydroxymethylphosphines of the general formula ##STR2## in which R and R' have the meanings given above, to a thermal rearrangement reaction at temperatures higher than about 90.degree. C or, in the presence of a catalyst, at temperatures within the range -10 and +250.degree. C.
