Patent CA-2196587-A1 (CA)
Inventor: GENTA GERALD
IPC: G04B19/08
Filed: 1997-01-31
Abstract: The control mechanism of means for displaying hours and minutes includes a tilting member (15) biasing against, under the effect of a return spring and via a pawl (18), a spirally shaped cam (12) located at the center of the movement, and which makes a full rotation in one hour. The tilting member (15) is lifted progressively by the action of the cam (12) to fall back instantly, once each hour. During this instantaneous falling back motion of the tilting member (15), a toothed sector (23) carried by the same drives, via a train of gears (24, 25, 26), a central pinion (27) carrying the minute hand. Thus, once at each hour, the minute hand is instantly reset to its initial position. The tilting member (15) carries a pawl (30) cooperating, at each of the instant falling back motions of the tilting member, with a star wheel with twelve branches, which rotates at the center of the movement and which carries a disk indicating hours, of which the display it thus of the so-called "incremental" type .
Patent CA-2196615-A1 (CA)
Inventor: KENNEDY FRANCIS ALAN
IPC: A62B23/00
Filed: 1997-02-03
Abstract: A filtering device to be used in conjunction with an air tight face mask shell (4) to separate and trap air borne solid particles and water soluble gaseous contaminants from inhaled air. The filtering process is accomplished by the passage of inhaled and exhaled air through a series of ducts (5) formed by a matrix of plates (2) contained within the cell body (1). The entire cell is fabricated of thermally conductive non-corrosive metal. The exhaust flow of warm, moist exhaled air through the ducts (5) deposits a film of condensed water on the internal surfaces of the ducts. The changes in direction, pressure, density and velocity which are imposed on the flow of incoming air by the convoluted shape of the cell ducts causes air borne solid particles and water soluble gaseous contaminants to be forced into contact with the moisture laden internal surfaces by the action of centrifugal force, laminar flow and turbulence. The contaminants are trapped and held by the film of moisture in much the same manner as they would be held in the respiratory tract. The outward and downward flow of exhaled air combined with gravitational force serves to prevent the condensed water and contaminants from reaching the upper end of the cell and entering the mask.

Title: Recovery process in a pulp mill
Inventor: PUDAS ROLAND
IPC: D21C11/00
Filed: 1997-12-29
Abstract: A substantial and increasing problem with the pulping chemical recovery system, is the presence of chloride and potassium in the spent liquor entering the recovery boiler. Chloride and potassium increase the stickiness of carryover deposits and dust particles to the recovery boiler tubes, which accelerate fouling and plugging in the upper part of the recovery boiler. The present invention relates to a process by which the content of potassium ions in a recovery system for pulping chemicals can be reduced. The process comprises bringing spent liquor to a recovery boiler, burning said spent liquor, collecting precipitator dust formed, forming a solution by dissolving the precipitator dust in a liquid, where the solution of precipitator dust is subjected to a treatment with an inorganic ion exchange material in order to remove at least a part of the potassium therein.
