  • Patent number: 10752526
    Abstract: A method of decreasing the concentration of certain contaminants in liquids by the chemical reduction of the contaminant using a hydride. A suitable reactor is charged with the contaminated liquid. An amount of catalyst and then an amount of hydride are added to the reactor. The hydride reacts with the contaminant in the liquid, chemically reducing and thus destroying a portion of the contaminant and thereby reducing the concentration of the contaminant in the liquid. Additional hydride can be added to further reduce the concentration to meet a desired level.

  • Patent number: 6939408
    Abstract: A method for preparing a workpiece surface utilizing two more fluids of differing density and miscibility which create one or more fluid interfaces wherein the fluids are chosen such that the solubility or affinity of one of the fluids is high for a material to be removed from the workpiece surface while the other fluid has a low solubility or affinity for the material to be removed. The workpiece surface is treated by passing the workpiece through the fluid interface. The two or more fluids are preferably dispensed into an apparatus and allowed to settle into two or more predominant layers separated by an interface. Surface preparation techniques which may benefit from the present invention include etching, cleaning or drying processes and the like.

  • Patent number: 6907890
    Abstract: An apparatus and method for drying substrates. The inventive apparatus comprises: an object support member for supporting at least one substrate in a process tank having one or more support sections comprising capillary material. The inventive method is a method of removing liquid from a wet substrate in a process tank comprising contacting the wet substrate with capillary material. In another aspect, the invention is a method of drying at least one substrate having a surface in a process tank comprising: submerging the substrate in a liquid having a liquid level; supporting the submerged substrates in the process tank; supplying a drying vapor above the liquid level; lowering the liquid level or raising the substrate so that the liquid level is below the substrate, thereby removing a major portion of liquid from the substrate surface; and removing remaining liquid from the substrate surface with capillary material.

  • Patent number: 6904919
    Abstract: A method for separating a substance such as a hydrocarbon from a particulate material such as soil is provided. An aqueous slurry is formed and a shear force is applied to the slurry, such as in a reversible helical screw conveyor, while the slurry is vibrated. The substance thus separated can then be removed from the particulate material.

  • Patent number: 6905551
    Abstract: In a method and apparatus for cleaning the front surface of a mounted lens a web is moved to a lowered position against the lens. A first segment of the web is then slackened. The first segment of web is then rubbed against the lens. Following the rubbing the web is pulled taut while the web is still in the lowered position. A second segment of web can be wiped against the lens while the web is held taut. The first segment can be wet and the second segment dry.

  • Patent number: 6652665
    Abstract: A method of removing cured silicone polymer deposits from electronic components. The components are immersed in a preheated solution of a quaternary ammonium fluoride in a hydrophobic non-hydroxylic aprotic solvent with agitation. The components are then immersed in a preheated solvent consisting essentially of a hydrophobic aprotic solvent with agitation. This is followed by a rinse and spray of the components with a hydrophilic, essentially water soluble solvent, with agitation. The components are then immersed in a water bath and then rinsed with a pressurized spray of water and then dried with a N2 blow dry.

  • Patent number: 6638363
    Abstract: A cleaning apparatus for cleaning solder paste off the bottom side of a printed circuit board stencil includes a container of cleaning solution therein and a blade holder that is movable between a wiping position and the container of cleaning solution. A wiping blade is mounted in the blade holder. The blade holder, with the blade mounted thereon, is reciprocated back and forth when in communication with a stencil to be cleaned. The blade is moved from the wiping position in communication with the stencil into the cleaning solution in the container. A pneumatic piston and rotary actuator provides controlled movement of the wiping blade. The wiping blade may be vibrated during wiping to improve removal of solder paste from the stencil and the cleaning solution may be ultrasonically vibrated to improve removal of solder paste from the wiping blade. The wiping blade may also be pulsed into a sponge to remove excess cleaning solution prior to the next cleaning cycle.
