Abstract: The present invention relates to a distribution network comprising electric wires (5) for distribution of electric current, a plurality of tap-off facilities (6) with at least one socket means (9) for tapping off electric current to optional power-consuming units (1), and a central computer unit (10) communicating with the individual tap-off facilities. At least some tap-off facilities (6) in the network comprise a switch (13) and a regulating device (11) with a microprocessor (21), a user connecting a power-consuming unit (1) to one of said tap-off facilities being identifiable to the central computer unit (10) or to the regulating device (11) via a microprocessor in the power-consuming unit, and the regulating device, in case of accepted identification, keeping the switch (13) closed and permitting tap-off of electric current from the socket means (9), whereas, in case of non-accepted identification, the regulating device keeps the switch open and prevents tap-off of electric current from the socket means (9). The invention also relates to a device and a method for respectively permitting and preventing current supply from the network.

Granted: 2006-03-21
Abstract: Cette invention concerne un puits de forage (1), lequel est partiellement obstrué à l'aide d'une cloison ou d'un élément d'obstruction (5). Une boue fluide faite d'un mélange d'agrégats de matière particulaire est pompée dans le puits de forage à proximité de la cloison ou de l'élément d'obstruction. Ce mélange d'agrégats de matière particulaire contient au moins un composant de matière particulaire, chacun de ces composants de matière particulaire ayant une taille de particules moyenne et discrète différente de celle des autres composants de matière particulaire. Une pression de fluide est ensuite appliquée au matériau agrégé tandis que le fluide est drainé depuis ce dernier dans la cloison ou dans l'élément d'obstruction par l'intermédiaire d'un conduit de drainage de fluide. La pression du fluide et le drainage de ce dernier depuis le mélange d'agrégats sont combinés de sorte que le mélange d'agrégat soit compacté et transformé en un élément bouchon (11) sensiblement solide, capable de supporter des charges et de transférer des forces, et sensiblement imperméable au fluide. Cet élément bouchon permet de fermer hermétiquement une première zone du puits de forage et d'empêcher la communication de fluide entre celle-ci et une seconde zone de ce même puits de forage. On peut enlever facilement l'élément bouchon du puits de forage en lui envoyant un flux de fluide à haute pression, ce qui a pour effet de dissoudre ou de désintégrer ledit élément bouchon en une boue fluide pouvant être évacuée ou aspirée hors du puits de forage.

Title: Compositions for the detection of proteases in biological samples and methods of use thereof
Inventor: KOMORIYA AKIRA
IPC: A61K38/00
Filed: 1995-10-27
Granted: 2010-04-27
Abstract: The present invention provides for novel reagents whose fluorescence in-creases in the presence of specific proteases. The reagents comprise a characteris-tically folded peptide backbone each end of which is conjugated to a fluorophore.  When the folded peptide is cleaved, as by digestion with a protease, the fluo-rophores provide a high intensity fluorescent signal at a visible wavelength. These protease indicators are particularly well suited for detection of protease activity in biological samples, in particular in frozen tissue sections, because of their high fluorescence signal in the visible wavelengths. Figure 1 shows an HPLC  analysis of the D-NorFES-A protease indicator comprising 5'-carboxytetramethylrhodamine (C2211) as a donor fluorophore and rhodamine X acetamide (R492) as an acceptor fluorophore so that Figure 1 (A) illustrates HPLC of the intact indicator molecule before the addition of elastase; Figure 1 (B) illustrates HPLC where both fluo-rophores absorb after the addition of elastase and Figure 1(C) illustrates HPLC  after the addition of elastase where rhodamine X acetamide (R492) absorbs max-imally. This invention also provides for methods of detecting protease activity in situ in frozen sections.

Abstract: A load detection device for monitoring the engagement force between a tool and a workpiece, comprises means having a free end for transmitting a force, the force being transmitted at the free end.  A load cell has one face juxtaposed that free end of the means for transmitting a force, for monitoring the force of that force-transmitting means.  Biasing means is mounted between the free end and that one face of the load cell, the biasing means providing a biasing force to urge the load cell monitoring the force away from that free end.  A piston rod adapter is provided, having a blind bore at one end and an open end opposite that one end; the opposite end being slidably mounted to the free end of the means for transmitting a force.  The biasing means and the load cell are mounted in the blind bore of the piston rod adapter, and are interposed between the free end and the bottom of the blind bore.  Means for limiting the movement of the means for transmitting a force relative to the piston rod adapter are included; the limiting means being mounted to the means for transmitting a force such that the force transmitted at the free end of the means for transmitting a force is counteracted by the biasing means, and the net effect of the force is monitored by the load cell to determine the engagement force between the tool and the workpiece.

Then the background color and the foreground color of each block of the smaller grids are determined iteratively, using biasing information from each block's corresponding block, until the background and foreground colors of all of the blocks of all of the grids have been determined.          Finally, the foreground and background images are formed from the determined background color and foreground color of each block of the smallest grid.

Abstract: Glass containers are transferred from the dead plates of a forming machine of the I.S. type to an adjacent machine conveyor by 90° sweepouts, each of which is powered by an a.c. servo motor. The machine conveyor, which is also powered by an a.c. servo motor, conveys containers to a cross-conveyor, which extends perpendicularly to the machine conveyor and conveys the containers to positions adjacent the inlet of an annealing lehr.  The transfer of containers from the machine conveyor to the cross-conveyor is effected by a chain transfer device, and the cross-conveyor and the chain transfer device are each powered by an a.c. servo motor. Groups of containers are transferred in unison from the cross-conveyor to a moving conveyor of the annealing lehr by the reciprocating pusher bar of a lehr loader, and the operation of the lehr loader pusher bar which reciprocates along three (3) axes, powered by three (3) a.c. servo motors. The operation of each of the a.c. servo motors for the 90° sweepouts, the machine conveyor, the cross-conveyor, chain transfer device and the lehr loader pusher bar, and the operation of the annealing lehr, which is powered by an a.c. motor, conveyor is simultaneously measured and controlled to process containers at all times from the forming machine dead plates to the annealing lehr conveyor at predetermined controlled rates.

Abstract: A linear beam amplification device includes an axially centered electron emitting cathode and an anode spaced therefrom. The cathode provides an electron beam in response to a relatively high voltage potential defined between the cathode and the anode. A control grid is spaced between the cathode and anode for modulating the electron beam in accordance with an input signal. A signal input assembly of the linear beam amplification device comprises an axial input cavity into which the input signal is inductively coupled. The grid-cathode region is electrically connected to the input cavity.  A low impedance grid-anode cavity is disposed coaxially with the input cavity and is in electrical communication with an interaction region defined between the grid and the anode. The low impedance of the grid-anode cavity is provided by constructing the cavity of a material having a relatively high surface resistivity, such as iron. The high surface resistivity tends to reduce the Q (quality factor) of the grid-anode cavity, which also reduces the impedance of the grid-anode cavity. Alternatively, the grid-anode cavity may be tuned to define a transmission line having an electrical length approximately equal to n.lambda./4, where .lambda. is the wavelength of the input RF signal, and n is an even integer.
