Abstract: A dry vacuum pump, comprising a pump housing, which forms a plurality of suction chambers, wherein rotor elements are arranged in the suction chambers, in order to convey a pump medium from a high-vacuum-side inlet to an outlet. At least one rotor element is arranged in each suction chamber. The rotor elements are connected to a rotor shaft. The rotor shaft is supported by bearings, wherein a high-vacuum-side bearing is arranged in a cut-out. A sealing device is arranged between the high-vacuum-side bearing and at least one suction chamber adjacent to the high-vacuum-side bearing. The cut-out is connected, by means of a first channel, to a region of the dry vacuum pump in which there is a higher pressure than in at least one suction chamber adjacent to the high-vacuum-side bearing.

Abstract: A condition of a flexible pipeline may be monitored by scanning a section of the flexible pipeline with an ultrasonic scanner and using the ultrasonic scanner to produce a first ultrasonic signal that penetrates the section of the flexible pipeline and is used to create a set of condition data indicative of a condition present near or within an annulus of the flexible pipeline, the condition comprising pressure on or within the flexible pipeline.

Abstract: A system of nodes may communicate a signal between nodes in a manner that prevents looping the same signal through the same node. When a node receives a signal, it may evaluate whether the signal itself includes an identifier of the receiving node, indicating whether or not the receiving node has previously broadcast the signal. The receiving node may have an internal memory with a record of previously broadcast signals, against which it may compare a received signal to determine if the received signal is one that has been previously broadcast. If the signal has previously been broadcast, then the receiving node may discard the signal. If the signal has not previously been broadcast, then the receiving node may add its own unique identifier to the signal and rebroadcast the signal. The internal memory of the receiving node may also be updated to reflect the broadcast.

Abstract: A Roots pump comprises a plurality of multi-toothed rotary pumps, each forming a pump stage, and connection channels connecting respective adjacent pump stages. The invention provides that the connection channels are arranged in partitioning walls separating the adjacent pump stages.

Abstract: A vacuum pump comprises pumping elements arranged in a pumping chamber. An electric motor drives the pumping element. A frequency inverter is provided for changing the rotational speed of the electric motor. The frequency inverter is arranged in a frequency inverter housing immediately connected to the pump housing. An air cooler and a liquid cooler are arranged in the frequency inverter housing to cool the frequency inverter.

Abstract: The present invention relates generally to the photovoltaic generation of electrical energy. The present invention relates more particularly to photovoltaic arrays for use in photovoltaically generating electrical energy. Aspects of the present invention provide a variety of photovoltaic roofing elements and systems that include, for example, interlocking geometries to provide for water handling and integration with conventional roofing materials; wire management features that can protect wiring and associated electrical components from physical and/or environmental damage; and wind clip and ledge features configured to prevent against wind uplift of the photovoltaic roofing elements when installed.
