Patent CA-2257584-A1 (CA)
Title: Acoustic transducer system
Inventor: FLOEGEL KARL
IPC: G10K13/00
Filed: 1998-12-29
Abstract: The acoustic transducer system includes a flexural vibrating plate  coupled  to  an  electromechanical  transducer  and  so configured that  it  is  stimulated to higher order  flexural vibrations at the system operating frequency, at which nodal lines  form on  the  flexural  vibrating  plate  between which first  and  second  antinodal  zones  are  located  oscillating alternatingly opposite in phase.  For influencing the sound radiation, in the second antinodal zones oscillating in phase with respect to each other and opposite in phase in relation to the first antinodal zones one mass ring each is arranged on the rear side of the flexural vibrating plate facing away from   the   transmission   medium   concentrically   to   the centerpoint  of  the  flexural  vibrating plate.  Due  to  the increased mass  the  second  antinodal  zones  oscillate  at  a substantially  smaller  amplitude  than  the  first  antinodal zones so that the sound waves opposite in phase generated by the  first  and  second antinodal  zones  are  unable  to  fully cancel  each other out,  as  a  result  of  which  a  radiation pattern materializes having a pronounced directivity in the direction perpendicular to the flexural vibrating plate.

Patent CA-2293223-A1 (CA)
Inventor: BOURBONNAIS ROBERT ERNEST
IPC: G01N27/26
Filed: 1999-12-23
Abstract: This invention describes a new method to measure kappa number or lignin content of kraft pulps based on the voltammetric measurement of catalytic reactions involving lignin and redox mediators. This method comprises measuring the rate of regeneration of a lignin redox catalyst in the presence of pulp following its oxidation at a voltammetric electrode.     The intensity of the catalytic current generated at the electrode surface is shown to be proportional to the amount of lignin present in a pulp. Within pulp types (softwood, hardwood or oxygen delignified) linear relationships can be obtained between the intensities of the generated current and a range of kappa numbers. The redox characteristics and concentration of the mediator, and the voltage sweep rate of the voltammetric procedure, are among parameters that can be tuned to obtained linear relationships with kappa number of various pulps. Automation of this method can lead to development of a novel on-line electro-kappa analyzer to be used for either pulping or bleaching process control.

IPC: B60P1/64
Filed: 2000-02-15
Abstract: A carriage with a front end and a rear end can be stowed in a truck box or truck platform, and deployed to a position on the ground outside of the truck by providing a transfer arm having one end pivoted to the truck and the other end pivoted to the front end of the carriage. Roller guides are mounted on the truck, and the carriage has tracks which run in the roller guides for at least a portion of its movement between the two positions. The carriage has wheels adjacent the rear end, and a powered mechanism, typically hydraulic, is adapted to move the transfer arm between its two extreme positions. As the transfer arm begins to move away from the position in which the carriage is stowed in the truck, the front end of the carriage lifts upwardly while the carriage moves rearwardly, supported and guided by the roller guide means, until the wheels at the rear end of the carriage contact the surface on which the truck is standing. This causes the carriage to disengage from the roller guide means and eventually the carriage comes to a stop resting on the surface.
