Abstract: A fuse for an alternating current power circuit in the medium voltage (3.3 kV to 38 kV) range. The fuse comprises a sealed chamber and a first electrode (41) is mounted within the chamber, the first electrode having a substantially circular periphery (42) and being electrically connected to a first terminal (3) to which a first conductor may be connected. A second electrode (35) is arranged with a conductive surface internally of the chamber, the conductive surface being spaced from the first electrode. A coil (10) is connected in an electrical path between the second electrode (35) and a second terminal (18) to which a second conductor may be connected. An additional electrical contact (44) is mounted within the chamber and in direct electrical connection with the second terminal, and a fusible element (43) directly electrically connects the first electrode (41) and the additional electrical contact (44). An electronegative halogenated medium fills free space within the chamber. The normal current path between the first and second terminals and through the fuse is by way of the first electrode (41), the fusible element (43) and the additional electrical contact (44). The arrangement is such that when the fusible element (43) breaks, the resulting fault current forms an arc between the first electrode (41) and the additional contact (44), one root of the arc subsequently commutates from the additional contact (44) to the second electrode (35), the fault current flows through the coil (10) and induces a magnetic field, the magnetic field causes the arc to rotate around the first electrode in the electronegative medium, and the arc is thereby extinguished, so interrupting the fault current.

Abstract: The audio signal is processed by analogue to digital conversion, windowing, i.e. sampling of 20 ms blocks, pre-processing fast Fourrier transform analysis of frequency spectrum, and encoding according to psycho-acoustic aspects, i.e. irrelevant frequency components are weighted accordingly or discarded by means of a computer. The signal then passes via the transmitter and a communication channel which can now be of a narrower band-width, to the receiver. It is then decoded and the time domain signal is restored from the frequency domain digital signal. The uniform, continuous digital signal is then restored and, finally, passes through a d-a converter.

Abstract: Process for the fermentation of media containing carbohydrate, aided by bacteria forming butanol, acetone, ethanol and/or isopropanol, carried out in at least two stages, the first consisting essentially of continuous cultivation of the bacteria, the second, carried out continuously or in batches, consisting essentially of product formation. In order to achieve long-duration stability of the process, as well as an increase in productivity and in sugar break-down, the bacteria are immobilized during the second stage on a carrier material. Medium can therefore be drawn off at the product formation stage and the formed product can be isolated, thus avoiding inhibition caused by too high a concentration of the product. The device for implementing said process consists of a bioreactor, preferably an agitation pan bioreactor (4), and a reactor provided with a bacteria-retentive material, preferably a fixed-bed reactor (7), disposed successively. An external loop may be attached to the fixed-bed reactor (7) for product isolation, preferably continuous.

Abstract: A trunked communication signalling method is provided by a unifying signalling protocol in which subscribers request communication channels using only their individual IDs encoded into a single ISWs. The central decodes the call request, extracts the requesting subscriber's individual ID, which is cross referenced to determine the subscriber's talk-group affiliation(s). If the requesting subscriber's affiliation(s) are not known, the central commands the subscriber to transmit its affiliation using dual ISW signalling. In another aspect of the present invention, each subscriber automatically informs the central of a change in talk-group affiliation, thereby providing continual affiliation updates. In this way, many thousand subscribers are afforded access to a single trunked system, and control channel traffic congestion is minimized.

Abstract: A conductive liquid is dosed with a vessel having an upper rim and with a dip tube having a lower end projecting down into the vessel below the rim thereof. The vessel is periodically overfilled with the liquid such that periodically the liquid overflows the rim. Immediately after each overfilling of the vessel, the liquid is aspirated from the vessel through the dip tube until the lower end of the dip tube is above the surface of the liquid in the vessel. The resistance between the dip tube and the liquid in the vessel is continuously monitored and an error signal is generated either when the detected resistance falls below a predetermined threshold corresponding generally to that of the liquid after the overfilling but before the aspirating or when the detected resistance is substantially above the threshold after the aspirating and before the next overfilling. The flow of liquid out of the vessel is impeded except over the rim and through the dip tube at least during the aspirating step.

Abstract: The invention relates to a supporting plate with retention pins for a denture model which makes it possible to repeatedly remove the denture model or individual jaw tooth segments from the supporting plate or to exactly put back the denture model or individual denture model segment on the supporting plate without wearing out by friction the material of the model. This is achieved by means of a supporting plate for a denture model in which the height of the outer side wall of the arc-shaped impression on the supporting plate is lower in height relative to the inner side wall, and where the outer side wall is vertical or diagonal. Furthermore, wall segments having different contours make it possible to easily and rapidly classify the removed denture model segments.

Abstract: The blockable bone plate consists of a plurality of plate members which are connected to each other via webs. A screw hole is provided in at least some plate members, preferably in each plate member. The screw hole is surrounded by a spherical countersink on the upper surface of the plate. Provided internally in the screw hole there is an engagement contour which consists of contour valleys and contour peaks partially running in a horizontal and radial peripheral direction on the wall of the screw hole. The engagement contour is preferably produced by milling and has for example a pointed, round, trapezoidal or serrated configuration. A blocking thread is provided under the screw head of the screw intended for blocking. As the screw is screwed in, the blocking thread engages in the engagement contour. The particular advantages lie in increased security against the screw coming loose and in the possibility of also inserting the screw through the plate at an inclination. Furthermore, a bone plate is proposed which has the shape of an arc of a circle in the longitudinal axis of the plate and which requires less bending, particularly on the human lower jaw, and adapts to the bone in a more ideal manner.
