Inventor: BACHHAUSEN PETER
IPC: B09C1/10
Filed: 1990-01-04
Abstract: Méthode pour la décontamination microbiologique d'un sol, dans laquelle 1) le sol contaminé est extrait et traité, 2) le sol ainsi traité est entassé sur un sous-sol préparé sous forme de silos de régénération, 3) les silos sont traités avec de l'oxygène pendant la dégradation  microbiologique des contaminants. La méthode consiste à mélanger le sol contaminé avec, de préférence, des morceaux de béton et (ou) des gravats de construction, avant d'entasser le mélange sous forme de silos de régénération, le béton et les gravats ayant été réduits à une taille de ~ 10 mm, et préférablement ~ 6 mm, avant le mélange. Selon l'invention, il est possible de décontaminer rapidement même les sols à faible perméabilité à l'air et à l'eau, ainsi que les sols où la distribution des contaminants est très peu homogène ou contenant des concentrations de contaminants très élevées. Les résultats sont particulièrement bons lorsque les silos sont en plus aspergés avec de l'eau provenant de la propre station de traitement de l'installation.

Title: Safety circuit for the drive motor of a tractor
Inventor: FOX THOMAS R
IPC: A01D75/18
Filed: 1991-06-26
Abstract: SAFETY CIRCUIT FOR THE DRIVE MOTOR OF A TRACTOR            ABSTRACT OF THE DISCLOSURE               A  safety  circuit  for  a  tractor  and  implement combination includes a first switch responsive to movement of a lever actuating the implement to an inoperative position and a second switch responsive to movement of a lever actuating the drive  transmission  to  the  tractor  to  a neutral  position together with a seat switch responsive to the presence of the operator in the seat of the cab.  The safety circuit allows the operator to start the machine only when the transmission is in neutral and the implement is decoupled.   After the engine is started and running,  the  circuit prevents  the  operator  from leaving  the  seat  while  the  implement  is  engaged  or  the transmission is not in neutral.  A timer is coupled to the seat switch circuit to allow temporary movement of the operator from the seat.   A bypass switch on the implement drive allows the operator to leave the cab to observe the implement operating.

Inventor: HENKEL JOHN R
IPC: H01M50/50
Filed: 1991-06-28
Abstract: -i-ABSTRACT OF THE DISCLOSURE    A battery charging system has a effective pure DC power source charging at least one secondary charge acceptor utilizing an aqueous electrolyte.  The applied effective voltage is equal to or slightly greater than the full charge level of said acceptor cell.  An impedance/resistance is coupled between the charging means and the secondary charge acceptor cell.  The impedance/resistance is a value which reduces any AC component out of the secondary cell to no more than 5% of the total voltage out in order to reduce the counterelectromotive force responsive to the applied voltage.  The impedance/resistance is a value which is selected to set the capacitive reactance of the acceptor cell and the inductance reactance of the charging means at levels which reduce the counterelectromotive force of the acceptor cell throughout the full charge cycle in order to produce said cooling affect.

Patent CA-2055240-A1 (CA)
IPC: B05B1/26
Filed: 1991-11-13
Abstract: ABSTRACT           A nozzle assembly is interconnected with the delivery passageway or conduit from a hand pump sprayer.  The nozzle assembly has a first and second passageway, preferably conduits, which are connected to the delivery passageway or conduit and split the fluid exiting from the delivery passageway or conduit into two streams.  The cross sectional flow area of the first and second conduit means is smaller than the cross sectional flow area of the delivery conduit so that the velocity of the fluid increases upon entry into the first and second conduits located in the nozzle assembly.  Each conduit has a fluid outlet to the atmosphere.  The first and second conduits in combination with said fluid outlets define a discharge axis.  The first fluid conduit discharge axis intersects the second fluid discharge axis at an impingement angle of from 10° to 170° so that the fluid exiting each outlet intersects at a point exterior to the nozzle.  As a result the fluid exiting the first outlet collides with the fluid exiting from the second outlet to break the fluid into small droplets to form a wide angle mist.  The nozzle assembly is particularly useful for spraying viscous pan coatings containing vegetable oil.

Title: Method and instrument for nonlinear averaging compensated measurements
Inventor: DUKES JOHN R
IPC: G01N23/16
Filed: 1990-08-20
Abstract: Method and apparatus for measurement and control of an industrial process by detecting the average transmittance of a radiation beam which passes through the process material. A radiation source (28) having an intensity Io is positioned on one side of the material to be measured and a suitable radiation detector (32) is positioned on the other side. The transmitted radiation intensity, I, is measured by the sensor. An index Z commensurate with the degree of nonuniformity of the variable in the material is determined, and a process signal is generated from a quantitative relationship among I, Io, and the index Z. In a first embodiment implemented in a system for measurement and control of the basis weight of paper in a paper production process, the index Z is indicative of the nonuniformity of the material mass distribution in the sheet and is determined by measurements with a separate formation gauge operating on-line with, but independently of, the basis weight sensor. In a second embodiment of the invention implemented in such a paper making process, the index Z commensurate with the degree of nonuniformity for the mass in the material, is derived from the standard deviation of the detected radiation intensity signal, or the equivalent standard deviation of the basis weight output signal.

Abstract: L'invention se rapporte à un procédé amélioré d'initiation de processus de commutation entre les secteurs d'un canal vocal, de façon à réduire les interférences affectant les canaux vocaux divisés en secteurs. Les secteurs qui sont adjacents entre eux et qui sont adjacents à la partie arrière du secteur qui dessert l'unité mobile sont balayés pour permettre de déterminer la qualité du signal. Un message de demande de commutation est envoyé vers l'unité de commande de la cellule, lorsque la qualité du signal détecté par n'importe lequel des secteurs balayés est meilleure que la qualité du signal lu dans le secteur desservant l'unité mobile. Lorsque le message de demande de commutation est reçu par l'unité de commande de la cellule, un canal vocal est attribué à la cellule et au secteur qui sont associés au secteur balayé désigné comme comportant le meilleur signal. C'est alors que se produit l'initiation du processus de commutation entre le canal vocal qui est en train de desservir l'unité mobile et le canal vocal nouvellement attribué dans le secteur désigné.

IPC: C08B37/00
Filed: 1992-05-21
Abstract: A   method   for   continuously   purifying   a polysaccharide  comprises  the  steps  of  continuously  and simultaneously   feeding   an aqueous   solution   of   a polysaccharide  and  a  hydrophilic  organic  solvent  which does not solubilize the polysaccharide,  mixing these two kinds of liquids with a rotary turbine to precipitate the polysaccharide,  cutting  the  precipitated  polysaccharide with  an  interlocking  cutter  which  comprises  a  fixed cutter and a rotary cutter,  and continuously withdrawing a suspension of finely cut polysaccharide particles.  The resulting polysaccharide  is not  in the form of strings, but in the form of fine particles and thus it is never adhered  to  an  apparatus  for  purification  and  does  not cause any retention within the apparatus. The particulate polysaccharides   obtained   by   the   method   are   easily separated from the resulting suspension and dehydrated.
