Patent CA-2058807-A1 (CA)
Title: Shaft seal arrangement
Inventor: CORDTS DETLEF
IPC: F16J15/54
Filed: 1992-01-06
Abstract: ABSTRACT  A shaft seal arrangement for the removal of liquid from a cavity that surrounds a rotatable shaft, the liquid having leaked into the cavity from a seal gap.  The cavity and/or the machine elements which define the cavity are provided with a heat source for the evaporation of the leaked liquid.  The heat source ensures that the leaked liquid is evaporated even if a machine rotating the shaft is only operated for a short period of time, in which case the heat generated by operation of the machine itself would not be sufficient to evaporate liquid leaked into the cavity.
Patent CA-2059246-A1 (CA)
Inventor: ANDERSON ROGER W
IPC: C23C18/16
Filed: 1992-01-13
Abstract: A process for removing, from spent electroless metal plating bath solutions, accumulated byproducts and counter-ions that have deleterious effects on plating.  The solution, or a portion thereof, is passed through a selected cation exchange resin bed in hydrogen form, the resin selected from strong acid cation exchangers and combinations of intermediate acid cation exchanges with strong acid cation exchanges. Sodium and nickel ions are sorbed in the selected cation exchanger, with little removal of other constituents.  The remaining  solution is subjected to sulfate removal through precipitation of calcium sulfate hemihydrate using, sequentially, CaO and then CaCO3.  Phosphite removal from the solution is accomplished by the addition of MgO to form magnesium phosphite trihydrate.  The washed precipitates of these steps can be safely discarded in nontoxic land fills, or used in various chemical industries.  Finally, any remaining solution can be concentrated, adjusted for pH, and be ready for reuse.  The plating metal can be removed from the exchanger with sulfuric acid or with the filtrate from the magnesium phosphite precipitation forming a sulfate of the plating metal for reuse.  The process is illustrated as applied to processing electroless nickel plating baths.

Filed: 1992-02-13
Abstract: LINE LEAK DETECTOR AND METHOD     Abstract of the Disclosure An apparatus and method for employing the apparatus in testing underground fluid containing lines for leaks.  The apparatus comprises (a) a differential pressure transducer mounted to a reservoir for indicating volumetric change in the reservoir; (b) a temperature transducer mounted in the reservoir for monitoring temperature fluctuation in the reservoir; (c) a gauge pressure transducer mounted in the reservoir;  (d)  a remote temperature sensor and a data acquisition   and   processing  system.   The method for employing  the  apparatus  comprises  of  connecting the apparatus to the  line under test and entering certain parameters of a line under test and product temperature into the test computer.   The test system then monitors volumetric change in the reservoir as well as pressure and temperature fluctuations  in the  line under test at 30 second intervals.   At the end of the predetermined test period, the system calculates the leak rate during each five minute interval of the test as well as a cumulative leak rate.   The trends in the leak rate data during the test are then analyzed to determine whether the calculated cumulative leak rate is accurate.

IPC: E05C1/12
Filed: 1992-02-18
Abstract: Ce dispositif d'embrayage mécanique à validation électrique oblige une opération manuelle supplémentaire afin de permettre à la partie électrique de fonctionner sous un très faible courant. Ce système, utilisé dans une serrure, comprend un boîtier dans lequel se retrouvent la serrure, les piles, le circuit électronique et le mécanisme d'embrayage ci-haut nommé. Ce dernier est formé d'un cylindre fixé au boîtier dans lequel une tige cylindrique peut tourner librement mais qui peut agir en translation de façon limitée, d'une part par une buté fixe et d'autre part par une buté mobile agissant comme premier mécanisme de blocage. Cette dernière recule lorsque la tige est tirée et elle peut être bloquée dans cette position par une dent, appartenant à un levier qui pivote sur un axe et qui cherche à s'approcher de la buté mobile lorsque cette dernière recule, constituant ainsi le deuxième mécanisme de blocage. Mais le levier peut être empêché d'avancer par la plaque mobile d'un petit relais si le système n'est pas validé. Si validé, la dent empêche la buté mobile de bouger, permettant ensuite à la tige d'avancer pour faire la jonction avec le reste du dispositif à embrayer. Un bouton supplémen-taire permet l'embrayage manuel lorsque désiré pour, par exemple, barrer la porte en sortant, sans avoir à actionner le système électrique.

Title: Apparatus for reversing airflow within a duct
Inventor: BERNER ERLING
IPC: F24F7/06
Filed: 1993-03-26
Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus is provided for reversing airflow within a duct utilizing a single, stationary fan.  The apparatus includes a valve system which through the utilization of a cam or solenoid provides for movement of the valves to reverse the airflow.  The apparatus includes a duct having a first end and a second end, which are open, and a stationary fan placed therebetween.  The fan has an intake side and an outlet side; at all times while the fan blades are rotating, air is flowing from the intake side to the outlet side.  In one embodiment, valves are hingedly attached to the sides of the duct such that their movement by a solenoid and linkage can open and close ports in the ends of the duct.    In another embodiment, flexible valves are located adjacent the fan at opposite ends of an axis perpendicular to the axis of rotation of the fan blades and close one half of the openings at the first and second end.  The valves are rotated in such a manner to close the other half of the openings at each end to thus reverse the air flow through the duct. At all times, air flow across the fan maintains the same direction.    In another embodiment, rigid arcuate valves surround the fan and have ports opposite one another.  The valves are rotated by a solenoid or cam system in such a manner that the air flow through the duct is reversed.
