Abstract: A method for locating a defect in an electric link includes measuring at least one part of components of an electromagnetic field in a vicinity of an estimated location of the defect at plural places along the link; deducing, via a processor, from the measuring an estimation of variation of at least the part of the components of the electromagnetic field along the electric link in a vicinity of the estimated location of the defect; and estimating, via the processor, a new location of the defect as a function of the estimated variation of at least the part of the components of the electromagnetic field.

Abstract: A method for detecting a defect in an electric link, which transmits, at a first moment, an electric signal having a predetermined propagation speed from an end of the electric link, and detects, at a second moment, reception of an echo of the electric signal. The method further establishes a model of the variation of the electric signal propagation speed in the electric link on the basis of the length of the link through which the signal flows, and estimates a first location of the defect based on the difference between the first and second moments, on the predetermined propagation speed at the start, and on the speed variation model in the link.

Abstract: The invention relates to a device (10) for producing and/or processing plastic material mixtures comprising a mixing head (11) which has one or several inlets (15) for the mixture constituents and in which a mixer (17) provided for mixing the constituents is rotationally driven. An outlet (22) is provided in the mixing head for ejecting the finished mixture. Said outlet can be closed or opened by the head of the mixer in the manner of a nozzle needle. To this end, the mixer is arranged in the housing (12) of the device such that it can be axially displaced. In order to prevent an abrupt opening or closing of the outlet, which can thus lead to losses in quality when using sensitive plastic materials, the invention provides that the raising and lowering of the mixer in the mixing head is effected via a mechanical cam drive (40) comprising at least one actuating cam (42) which interacts with a lifting element (60) that acts upon the mixer (17) or the shaft thereof (24).

Abstract: This invention relates to a measuring apparatus for measuring the gas loading of a liquid, comprising a measuring device which substantially consists of a piston pump, by means of which a sample quantity of the liquid is subjected to a reduced pressure in a measuring cylinder chamber and the dissolved amount of gas is thereby desorbed and can be determined via the gas law by changing the conditions of pressure and/or temperature in the cylinder chamber. The measuring apparatus is of particularly compact construction and for this purpose is provided with a servomotor as an actuating drive for the piston pump, which servomotor not only enables the reduced pressure to be generated in the measuring chamber but also ensures the return of the measured test sample from the measuring cylinder chamber after the measuring operation.

Abstract: A self-contained device for self-service delivery of electrical energy, comprising a plurality of terminals, each capable of being connected to an electrical appliance, and a central management unit, operable independently of the terminals. The central management unit serves to: (1) manage distribution of electricity from an electrical supply grid to each of the terminals, (2) manage interaction between a prepayment instrument and users of the terminals, and (3) manage connection of the terminals to the electrical supply grid for transmission of electricity therebetween for either a period of time or a quality of electricity, as determined in response to a signal from the prepayment instrument indicating prepayment by a user.
