Abstract: A multiphase pump includes a housing having a flow inlet and a flow outlet which are fluidly connected to each other via a flowpath, a rotor arranged in the flow path which propels a fluid from the flow inlet to the flow outlet via the flow path, the rotor has a longitudinal axis which extends for a length of the rotor and a multiphase impeller arrangement, at least one leak path which permits a reverse flow of the fluid from the flow outlet to the flow inlet, and at least one channel which is arranged within the housing, the at least one channel directs a liquid from a liquid source to one of the at least one leak path in the multiphase pump.

Abstract: In one aspect, an apparatus includes a ready circuit to output a ready indicator when a supply voltage provided to the ready circuit and a voltage regulator is sufficient to operate the voltage regulator. In turn, the voltage regulator is to receive the supply voltage and output a regulated voltage, receive a first current from the ready circuit and control the regulated voltage based on the first current when the ready indicator is inactive. The apparatus further includes a bias circuit to receive the regulated voltage and generate one or more bias currents, which may be provided to an output circuit to output one or more bias outputs to one or more client circuits therefrom.

Abstract: A formwork includes a plurality of interconnectable disposable formwork elements for the casting of, for instance, foundations, sustaining walls, etc. in concrete and which is cheaper and wherein the formwork operation is rapidly effected, and at the same time it may be done by a person not skilled in the trade. Each formwork element (1) consists of an elongated, thin-walled, cylinder-shaped element, which is provided with coupling members on the neighbor element(s) for the interconnection of adjacent cylinder-shaped formwork elements so that, upon filling of concrete into the interconnected cylinder-shaped formwork elements, a row of fused concrete columns is formed constituting a wall on which the formwork elements may form the external surface(s) or from which the external portions of the formwork elements may be removed.
