Inventor: HRZAN E
IPC: H02J3/18
Filed: 1979-10-02
Abstract: A stability limit detecting circuit for a controlled synchronous compensator (condenser) comprises a sensor 1 operating as a phase discriminator to provide a signal U5 dependent on the reactive current supplied to the compensator, a sensor 2 providing a signal U6 dependent on the stator voltage supplied to the compensator, a circuit 4 for modifying said signal U6 to provide a modified stator voltage signal U7, and an output means (3) responsive differentially to the signals U5 and U7 and operating to produce a stability limit dependent output signal U8 whenever the signal U5 exceeds the signal U7, the signal U8 being linearly proportional to the difference (U5-U7). The output signal U8 may be used to control the field excitation of the synchronous compensator in a sense tending to reduce the output signal U8 and thereby to prevent unstable operation of the compensator. <IMAGE>

Abstract: The particle size range of a paper pulp suspension is determined by flowing the suspension up a measuring tube having a filter at the bottom thereof. When a plug of suspended material has formed, the inlet of the measuring tube is closed off. A liquid is then fed to a member which forms a gap in the plug of material and passes up through a measured portion of the suspension. The time taken for the liquid to pass through the plug to a given height is indicative of the mean particle size of the suspension.

Abstract: An ultrasonic flowmeter of the upstream/downstream sonic propagation type includes two transducers mounted externally on the same side of a flow conduit. The transducers are coupled to respective sonic probes which transmit and receive acoustic pulses between the transducers through the fluid by "bouncing" the pulses off the opposite pipe wall. Additionally the meter maintains a smooth bore in the measurement region so that the acoustic pulses are refracted at the probe/fluid interface and hence propagate along a sonic path that varies depending on the sonic velocities within the fluid and the probe. An acoustic path of known length is included within at least one of the probes along which a portion of the generated acoustic pulses propagates, thereby providing for a third sonic measurement which represents the transmit time in the probe. The three sonic propagation time measurements are necessary and sufficient to specify the flow velocity independent of sound velocity changes in the fluid and the probe and hence of changes in the path of propagation.

Abstract: A method and apparatus for coating both sides of a moving web, such as a paper web, with the same coating material on both sides by feeding the web downwardly between a rotating support roller and a coating blade directed against said roller. One side of the web is partially wrapped around said roller and a first excess of coating material intended for the web side facing said roller is applied to the roller before or at the point of contact between said web and the roller. A second excess of coating material is applied to the other side of the web by feeding the web through a dam of coating material arranged below said contact point-in the moving direction of the web-said dam being formed substantially between said coating blade and holder and the said other side of the web. The excess coating material is laterally expressed in said dam beneath the top level thereof.

Abstract: An apparatus for evacuating packages (1) with rotating evacuation chambers (10) is proposed. In order to prevent particles of filling material being sucked out when air is sucked out of the packages, the speed at which air is sucked out is to be kept within limits by control of the low pressure region. To achieve this, the control slots (27, 28, 29) of the low pressure region control device (20) are given adjustable widths. Each control slot is composed of a groove (21, 22, 23) of the same width and a strip (24, 25, 26) which is adjustable within the said groove (21, 22, 23). The strips can be adjusted from outside by means of cams (35) and back gearing (38, 39). <IMAGE>

Date Jul. 26, 1990.A fastening device in the form of a plug and a screw is adapted for installation in a blind bore of a thick wall or in a through hole in a thin wall. The plug is formed as an elongated body having a central longitudinal hole. The body has inner and outer end portions and two parallel slots extending longitudinally between the end portions to define four legs arranged circumferentially around the body. The legs diverge from the end portions to form an increasing diameter for the body which reaches a maximum at the center of the body. When the plug is inserted into a blind bore the legs are displaced inwardly to reduce the size of the central longitudinal hole so that when the screw is inserted into the plug, the screw will exert force on the legs to press the legs against the wall with strong radial forces. When the plug is inserted in a thin wall, threaded engagement between the screw and the inner end portion of the plug produces longitudinal displacement of the inner end portion and radial deformation of the legs to provide clamping pressure at the back of the wall at four distant locations.

Abstract: A binding for a cross-country ski shoe in which the shoe is mounted for pivotal movement about an axis transverse to the longitudinal axis of the ski. An elastic bumper exerts a return force on the shoe when the shoe is lifted from the upper surface of the ski. The elastic bumper is brought into a prestressed condition during the closing of the binding. The prestressing is achieved by either the displacement of the shoe with respect to the elastic bumper or displacement of the elastic bumper with respect to the shoe. This displacement may either be slidable or pivotal movement of a carriage.

Abstract: A method for extracting gaseous contaminants in the form of mercury and toxic, organic compounds, such as dioxins, furans and the like, from a gas. The method is characterized by first passing the gas through a first filter substance having selenium as an active ingredient, so as to take-up essentially all mercury. The essentially mercury-free gas is then passed through a second filter substance which is able to take-up toxic organic compounds and which can be destroyed or regenerated by combustion. The inventive filter arrangement includes a first filter substance having selenium as its active ingredient. This first filter substance is disposed upstream of a second filter substance which is capable of adsorbing or absorbing toxic, gaseous organic compounds, such as dioxins and furans. <IMAGE>
