Patent CA-2301844-A1 (CA)
Title: Enhancement of light activation effect by immune augmentation
Inventor: CHEN JAMES C
IPC: A61N5/06
Filed: 1998-08-27
Abstract: The efficacy of a plurality of PDT treatments following at least an initial PDT treatment is enhanced by increasing the neutrophil count of the patient substantially above a normal level. The increase in the neutrophil count leads to a more rapid removal of dead abnormal cells and stroma that have been destroyed, thereby enabling light administered in subsequent PDT treatments to more effectively reach and destroy still living abnormal cells on the surface of the tumor. The accelerated removal of dead tumor cells also enables a more accurate assessment of the treatment progress, since the actual tumor size should be more evident in image of the site. By enabling a tumor to be more rapidly destroyed by multiple PDT treatments, the risk of metastatic spread of abnormal cells away from the treatment site is also reduced.

Title: Tracked vehicle steering system with steering pump monitoring
Inventor: TOPPIN SCOTT ALLEN
IPC: B62D11/10
Filed: 2000-03-30
Abstract: A control system is provided for a tracked vehicle drive/steering system having an engine driven hydraulic steering pump which drives a hydraulic steering motor.  The steering pump is responsive to steering control signals representing a status of an operator manipulated steering wheel. The steering motor provides an input to a differential track drive mechanism which responds to manipulation of the steering wheel and drives left and right tracks to turn the vehicle. The control system includes a control unit which receives signals from an engine speed sensor, a steering motor rotation speed and direction sensor, and the steering control signals. The control unit calculates a motor speed threshold value as a function of sensed engine speed and steering control signals, and generates a fault signal as a function of a relationship between the steering motor speed signal and a motor speed threshold value. The control unit generates an overspeed fault signal when the steering motor speed signal is greater than the motor speed threshold value or less than a negative motor speed threshold value, and generates a data conflict fault signal when the steering motor speed signal is less than a negative minimum motor speed threshold value or greater than a minimum motor speed threshold value. The control unit, when the vehicle is not being commanded to turn by the steering control signals, generates a minimum threshold value, and generates an overspeed fault signal when the motor speed signal is greater than the minimum threshold value or is less than a negative minimum threshold value.

Title: System for extracting soluble heavy metals from liquid solutions
Inventor: ROSENBERG EDWARD
IPC: B01J39/08
Filed: 1997-11-03
Abstract: A process for removing ions of dissolved heavy metals and complex heavy metals comprises providing a treatment zone in which is contained an extraction material having an activated surface that has an affinity for heavy metal ions and complex heavy metal ions. The activated surface is the reaction product of a polyamine with a covalently anchored trifunctional hydrocarbylsilyl that yields non-crosslinked amino groups to which functional chelator groups can be covalently attached.  The activated surface of the extraction material is formed by first hydrating the extraction material surface and then silanizing the hydrated surface with a short chain trifunctional silane having a hydrocarbon substituent containing 1-6 carbon atoms and a terminal leaving group, and then reacting a polyamine with the hydrocarbylsilyl from the silanization of the hydrated surface so as to form an aminohydrocarbyl polymer covalently bound to the extraction material surface.
