Patent CA-2148192-A1 (CA)
Title: Soap foam generator
Inventor: LAWRENCE MICHAEL E S
IPC: B05B7/00
Filed: 1995-04-25
Abstract: A device  for mixing air, soap  and water and delivering the resultant  foamy soap mixture to  a spray  wand, comprises  a mixing  chamber able  to withstand  the  high  pressures  existent  when  a pressure  washer system  is in  the wash  or rinse mode;  a high-pressure  inlet line;  an air-supply line with a pressure regulator and a check  valve; a soap-supply  line with a regulator  valve; and a discharge line with a high pressure gauge; all  of which  are housed in a  container.    When a soap-applicator nozzle is  attached to the  end of  the spray wand,  the resultant system pressure drop to near zero causes  the pressure washer  soap syphon to  introduce   soap  into  the   pressure  washer discharge line.  The amount of soap thus  syphoned is regulated  by a valve   The soap/water mixture then  enters  the  mixing chamber,  where  air  is forced  into  the mixture.    The  air enters  the mixing chamber  through an  air-supply line and  a check valve.   The air pressure in  the air-supply line forces  open the check valve  when the system pressure is near zero.   The action of introducing air into the  soap/water mixture  creates a  thick foamy  mixture which  discharges  from the  mixing chamber to the supply hose  to the wash wand where it  is applied to the surface to be cleaned.  When the  soap-applicator  nozzle  is exchanged  for  a high-pressure wash nozzle, the resultant high pressure causes the pressure washer soap syphon to cease  operating and  the check  valve in  the air supply  line  closes.    Clear  water  under  high pressure now enters and exits the mixing  chamber, travels  to  the  spray  wand  and  is  discharged through the high-pressure nozzle in order to rinse the object surface clean.

Filed: 1994-01-07
Abstract: A process for improving the impact resistance of a coated plastic substrate, particularly those polymers having a high refractive index, comprising applying an aqueous polyurethane as a primer layer to at least one surface of the plastic substrate, at least partially curing the aqueous polyurethane dispersion by air drying at ambient temperature, applying a coating composition over the polyurethane primer layer, and curing the coating composition to form an abrasion resistant hard coat. Preferably, the aqueous polyurethane dispersion is air dried at ambient temperature for less than one hour before application of the abrasion resistant coating composition. The process provides an impact enhancing, abrasion resistant coating system having strong interfacial adhesion that is preferably transparent for application onto preferably transparent plastic articles, such as ophthalmic lenses and safety eye wear.

Title: Method and apparatus for flash correlation
Inventor: PROKOSKI FRANCINE J
IPC: G06T7/00
Filed: 1993-12-02
Abstract: Flash correlation instantaneously compares (52) two or more patterns (20, 50) to determine whether they are the same or essentially the same regardless of the complexity of the images, and in spite of the addition of noise, local changes, and variations in resolution and focus. Flash correlation artifacts (58) also provide cues to quantitative assessment of relative movement, stretching, blurring, and warping of one image with respect to the other. Presence of a flash correlation artifact between two stacks of patterns (58) is sufficient to identify the stacks as containing at least one pair of massively correlated patterns (62). Precise control of registration, image size and orientation is not required. An image may be combined with other images, either by overlays or concatenation, and still be identified. A flash correlation engine may utilize optical, analog or digital processing to provide rapid sorting, classification, and identification functions with minimal computational complexity.

Filed: 1993-12-06
Abstract: A plate heat-exchanger (12) has an assembly of plates (16) defining and separating alternate passages (14, 16) for the flow of a refrigerant and a heat-exchange fluid. Aligned holes (15) in the plates (16) provide inlets and outlets for the refrigerant and heat-exchange fluid to the respective passages (14, 16). A refrigerant distribution tube (26, 37) is located in the refrigerant inlet defined by holes (15). The tube (26, 37) has outlet apertures (27, 38) which direct refrigerant into the refrigerant passage (14). Blanking members (29, 39) blank off part of the opening into each refrigerant passage (14) to confine the refrigerant flow from the apertures (27, 38) to a predetermined path towards the plate centreline to ensure even refrigerant distribution.

Patent CA-2166169-A1 (CA)
Inventor: WATTS LESLIE M
IPC: B65D71/50
Filed: 1995-12-27
Abstract: A novel carrier for carrying a group of items, such as cans, bottles or the like which hold beverages, foods or the like, is made of a substantially transparent, plastic material having micro-embossed partial cube-corner type retro-reflector elements on a surface of the carrier.  Each item includes an individual machine readable bar code thereon which is at least partially covered by the reflector elements.  The package has a machine readable bar code thereon which is not covered by the reflector elements on the carrier.  The reflector elements prevent the individual bar codes on the items from being read by a typical bar code reader beam by reflecting the light emitted from the bar code reader so the light cannot penetrate the carrier and read the bar code underneath the reflector elements.  The bar code on the package, which when scanned by the bar code reader beam will retrieve package information, can be read by the reader since it is not covered by the reflector elements.

Abstract: An essentially solvent-free acrylic polymer is produced from acrylic monomers while removing the reaction solvent during the polymerization process. The polymer is foamed and crosslinked to provide a pressure-sensitive cellular material of a wide range of tack and adhesion, depending on the extent of the crosslinking reaction of that polymer. The foaming is achieved by a spontaneous release of gaseous substance from the desiccating agent in the formulation during the crosslinking process. The foamed product is used for desiccating sealed systems.

Title: Liquid separator and polishing filter therefor
Inventor: ROSE WILLIAM C
IPC: C02F1/58
Filed: 1996-04-29
Abstract: This invention relates to waste water treatment, more specifically this invention relates to transportable decontamination system for water which is pumped from manholes and equipment vaults.  The separation of water and contaminants is accomplished by a five module system.  The first module removes 98% of the solids from the waste stream by use of staggered baffles.  Module two reclamates the free oil present in the liquid flow with an coalescing water oil separator.  The third module removes solids still left in the stream which are greater than 20 microns by use of a size discriminating filter.  The fourth and fifth modules are bonding tanks used to encapsulate hydrocarbons and heavy metals respectively.  The sequence in which the contaminated flow enters each of the modules is essential to the effectiveness and efficiency of the filtration process. The polishing filter for the waste water treatment system has the capabilities for removing small solids and hydrocarbons present within a liquid flow is a filtration device to be used either in conjunction with processes already in existence or as a stand-alone unit.   The polishing filter can be used for marine,  commercial or industrial activities.  Small solids will be discriminated by size by a removable and replaceable bag filter.   Residing inside the bag filter is the polishing filter bonding media, a hydrocarbon encapsulation agent used to separate and bond emulsified and dissolved oils.  This bonding media is contained inside a porous membrane bag which is also removable and replaceable.  The addition of this device to already existing equipment utilized by ocean vessels and commercial and industrial activities will enhance the decontamination process and assist in compliance with local, national and international clean water laws for effluent from ships and shore-based activities.
