Patent CA-2077126-A1 (CA)
Inventor: SMELCER JIM C
IPC: F23L17/04
Filed: 1992-08-28
Abstract: A high efficiency fuel-fired induced draft condensing furnace is provided with a horizontal vent termination assembly installed in an exterior wall of a building served by the furnace.  The vent termination assembly, constructed entirely from PVC plastic pipe and fittings, includes a combustion gas vent pipe connected to the furnace's draft inducer fan outlet, horizontally extending through an opening in the wall, and having an open discharge end positioned outwardly beyond the wall.  A larger diameter combustion air inlet pipe circumscribes the vent pipe within the wall opening and forms around the vent pipe an annular combustion air flow passage that is communicated with the furnace combustion air inlet.  A coupling member connected to the  outer  end of the  inlet  pipe has a diametrically enlarged end portion  positioned on the  outside surface of the wall, axially inwardly of the outer vent pipe, and forming an annular inlet to the flow passage between the two pipes.          The outer end of the vent pipe is left uncovered so as to permit direct, unimpeded axially outward discharge therefrom of furnace combustion gases.  In a similar fashion, the enlarged end portion of the coupling member is left uncovered so as to permit direct, unimpeded axially inward entry therethrough of outside combustion air.  Because the open outer ends of the concentric coupling and vent face in the same axial direction, the operating pressure differential across the furnace heat exchanger is substantially unaffected by changes in outside wind velocity and direction.

Title: Confocal microscope
Inventor: HARRIS MARTIN RUSSELL
IPC: G02B21/08
Filed: 1991-04-05
Abstract: A tandem scanning confocal epi-illumination microscope com-prising a light source (1), which may be a laser, for supplying a light beam (2) to a light condenser (18) which. may be a lens. Condenser (18) focuses the light onto object (20) to be examined so as to illumi-nate a point observational field on or within the object. Reflected, flu-orescent or scattered light from the illuminated point field is collected by condenser (18) and transmitted to a returning light receiver (36) which may be in the form of a camera (37) carrying photographic film (38). The outgoing light passing from light source (I) to condenser (18) and the returning light are transmitted via optical fibres and a light se-parator (5) to divert the returning light to receiver (36). The outgoing illuminating light is subjected to scanning movements to scan the ob-ject and the returning light is subjected to similar or tandem scanning movements to scan the photographic film (38). In one embodiment the scanning movements of the illuminating and returning light are pro-vided by two sets of scanning mirrors (16; 17 and 34, 35). In other ar-rangements, tandem scanning may be achieved by a pin hole or slit in a light screen located at an intermediate focal plane.

Title: Improved salt basket for crystallizer and method of use in zero liquid discharge industrial facilities
Inventor: SOLOMON ROBERT L
IPC: C02F1/00
Filed: 1993-04-21
Abstract: An improved salt basket for dewatering solids. The salt basket is ideally configured for use with a crystallizer or evaporator producing salts from industrial wastewaters. The salt basket system includes a pressurizable vessel having a screen floor situated above a bottom liquid collection head, an inlet for the brine/solids slurry from which solids are to be separated and dried, an inlet for air, an inlet for steam (the latter two inlets may be combined, where convenient), a feed brine inlet and a drain outlet (these two may by combined where convenient into a combination feed/drain connection), an automated system for introducing feed brine, and an automated system for removing the solids product, the latter system including an automated door with a fail safe clamp system design.      The vessel shape preferably includes sidewalls of substantially circular cross section with downwardly and outwardly sloping walls (either conical or flaring somewhat at the bottom) which are free from protuberances which would tend to prevent salt crystals from falling downwardly. A pivotally attached lower door has a hydraulic failsafe closure mechanism and looking safety latches to prevent the door from inadvertently opening. The process control design minimizes exposure of the salt basket interior to supersaturated solutions with precipitating solids therein, thus reducing coaling of the salt basket, by introducing feed brine rather than magma (crystal/concentrated liquor slurry) to the salt basket between crystal harvest cycles.

Title: Fluid control valve
Inventor: DEMAREST SCOTT W
IPC: B05B7/12
Filed: 1991-12-17
Abstract: A fluid control valve (10) which has a deformable valve member (12) which has a first portion (14A) with a fluid passageway (18) therethrough, a second portion (14B) which serves to add resiliency to the valve and, on the valve base portion (16) of the valve, an air inlet channel (56). The fluid passageway (18) is closed by a pressure-exerting member (34). Initial actuation of the valve by pressure on an actuator assembly (32) compresses a spring (46) which moves the pressure-exerting member (34) away from the deformable valve member (10), thus allowing the fluid passageway (18) to open. In a second embodiment of the invention, the fluid passageway deformable valve member remains open until pressed closed by actuation.

Title: Adjustable dampers using electrorheological fluids
Inventor: PETEK NICHOLAS
IPC: B60G17/015
Filed: 1993-07-09
Abstract: ABSTRACT OF THE DISCLOSURE Adjustable dampers using electrorheological (ER) fluids comprise one or more annular ER fluid transfer ducts in fluid communication with fluid chambers on opposite sides of the damper pistons. Each duct has one or more contoured surfaces or bands along a portion of the length of one or both walls of the ducts providing one or more annular constricted working areas through which the ER fluid is forced when displaced by movement of the pistons. By selectively applying a voltage/electric field across the primary working areas, the flow resistance of the ER fluid passing through the primary working area is increased which increases the damping force of the dampers.

Title: High wicking liquid absorbent composite
Inventor: JACKSON DAVID M
IPC: A61L15/60
Filed: 1993-08-03
Abstract: ABSTRACT OF THE DISCLOSURE      Disclosed herein is a high wicking liquid absorbent composite suitable for a wide number of uses including personal care products and the process for making the same. The composite is made from a relatively uniform mixture of from about 5 to about 20 percent fine wettable fiber, from about 3 to about 30 percent pulp fibers, from about 50 to about 90 percent superabsorbent and from 0 to about 10 percent binder,  the percentages being on a dry weight basis.  The mixture is compressed into a composite having a density of from about 0.1 to about 0.5 grams per cubic centimeter and a vertical wicking height of at least about 10 centimeters in one hour.  The process involves forming a sheet comprising 50 to 90 percent fine wettable fiber and 10 to 50 percent pulp fiber on a dry weight basis.   The sheet is then fiberized into a plurality of individual fibers within an air stream.   A superabsorbent is then mixed with the fibers from the fiberized sheet in the air stream to form a uniform mixture and the uniform mixture is deposited onto a forming surface to form a composite. After forming the composite, it is compressed to a desired density.

Title: Method of producing sodium hydroxide from white liquor
Inventor: KURITTU HANNU
IPC: C01D1/38
Filed: 1994-10-19
Abstract: The present invention relates to a method at processing white liquor obtained from the causticization stage of a pulp mill. According to the method, the white liquor, which principally contains sodium hydroxide (6) and sodium sulfide, is oxidized into polysulfide liquor (3), whereby the sodium sulfide is oxidized most advantageously with the help of a catalyst and an oxidizer such as air substantially into sodium poly-sulfide (7) and sodium thiosulfate. The method according to the invention is characterized in that the sodium hydroxide (6) contained in the white liquor is separated from the white liquor prior to the oxidizing step or from the polysulfide liquor (3) after the oxidizing step either entirely or partly by means of a diffusion dialysis process (4). The invention is further characterized in that the sodium hydroxide (6) separated from the white liquor is returned to the chemical circulation of the pulp mill.
