  • Patent number: 9914989
    Abstract: A process by which molten solder is purified in-situ, making the soldering process more efficient and yielding better results, particularly for lead-free soldering. Lead-free solder becomes practical for use since the temperature for reliable soldering is reduced. A layer of active additive is maintained on the surface of molten solder for scavenging metal oxide from the solder and assimilating metal oxide into a liquid layer. The active additive is an organic liquid having nucleophilic and/or electrophilic groups. As an example, a layer of dimer acid maintained on a wave soldering apparatus scavenges metal oxide from the bath, and assimilates dross that may form on the surface.

  • Patent number: 9439537
    Abstract: An apparatus and process of continuous, filtration of cooking oil during food processing to reduce and control free-fatty-acids and undesirable coloration in the cooking oil, including the movement of oil from a vessel to a flat-bed pressure chamber, where the oil is filtered through a stainless steel mesh screen under pressure. Differential pressure in the chamber causes the system to run the oil to a sister filter chamber which takes over the filter function while the first chamber cleans its filter. The filters are cleaned by inducing a high pressure inert gas into the filter chamber that dries the sediment, and then a mechanical sweep removes the sediment to a waste container. The resulting alternating process of filtering and filter cleaning between two chambers is fully automated and provides filtering that considerably extends oil life.

  • Publication number: 20150122748
    Abstract: A coolant for a machine is filtered by passing some of the coolant into a discharge tube having an opening, the discharge tube supporting a filter bag. Coolant flowing into the discharge tube flows out of the tube through the opening, and then through the bag, and the filtered fluid is recirculated. An end piece, pivotably mounted to the discharge tube, prevents the bag from falling off while in operation, but can be pivoted to a position which facilitates insertion and removal of the bag. When filled, the bag can therefore easily be removed and replaced with a new bag. The invention greatly simplifies the process of filtering a coolant fluid.

  • Patent number: 9023210
    Abstract: An osmotic power generation system and method for generating osmotic power includes a membrane chamber having a semi-permeable membrane therein defining a first portion and a second portion therein. The system also includes a first pump communicating a first fluid to the first portion and a second pump communicating a second fluid to the second portion. The second fluid has higher total dissolved solids than the first fluid. A second portion energy recovery device is in fluid communication with the second portion. A power generator is in communication with the second portion energy recovery device generating electrical power in response to the second portion energy recovery device and the pressure in the second portion.

  • Publication number: 20150108072
    Abstract: The invention relates to a method for sealing a filter chamber of a filter device, comprising a sequence of steps, including moving the recess plate close to the adjacent recess plate for building the pack, and securing the recess plate to the adjacent recess plate, piping a suspension into the filter chamber on a cake side of a filter cloth, letting a solid content of the suspension settle on the filter cloth as a filter cake, and a liquid fraction of the suspension permeate the filter cloth to a filtrate side thereof, and discharging the filtrate out of the filter chamber. The invention further relates to a recess plate for use in a filter device, the recess plate comprising a recess, and a groove encircling the recess, the groove being adapted to receive a sealing ring for sealing a filter chamber.

  • Publication number: 20150101994
    Abstract: Systems and methods for processing a fluid including a suspension of biological cellular components are disclosed including a single-use kit comprising a container for the fluid; a separation device for retaining selected biological cellular components and allowing other biological cellular components of said fluid to pass therethrough; a flow path connecting the container to the separation device, the container being configured, when in use, to be positioned so that gravity tends to flow fluid through the flow path. The flow path has a segment in close proximity to the container with a configuration including a positive slope, so that biological cellular components moving through the segment are subjected to a gravitational force tending to impede movement through the flow path segment. The flow path segment preferably has a generally circular configuration, and a diameter of approximately 1.5 inches. Alternatively, the flow path segment may have a generally S-shaped configuration.
