Patent number: 9903243Abstract: An oil separator includes a case and introduces blow-by gas of an internal combustion engine into the case. The oil separator then separates oil from the blow-by gas and discharges the separated oil from the case. The case incorporates electrode plates, which are arranged at intervals and face each other. A filter is arranged between any adjacent two of the electrode plates. The filter is formed of fibers, which are made of an electrically insulating first material, or polyester. A potential difference is created between the electrode plates.Type: GrantFiled: November 19, 2015Date of Patent: February 27, 2018Assignee: TOYOTA BOSHOKU KABUSHIKI KAISHAInventors: Yoji Horiuchi, Aoi Takano

Patent number: 9682871Abstract: An algae and bacteria contamination preventing apparatus and subsystem including a conduit forming a flush-water flow path between a potable water supply and a connection to a feed water entry port of a watermaker system. A check-valve and flush-water connector is installed in the feed water entry conduit. The flush-water flow path includes a valve means for opening and closing the flow path, a filter/ion-generator component a controller for sensing flush-water flow in the flow path, and in response thereto, applying electrical power to an ion-generating element of the filter/ion-generator component. The filter/ion-generator component also includes a filter element which removes undesirable chemicals from the potable flush-water before the ion-generating element introduces copper and/or silver ions into the flush-water. The valve means may be manually operated or be controlled by a watermaker system shut down controller.Type: GrantFiled: March 14, 2013Date of Patent: June 20, 2017Assignee: KATADYN DESALINATION, LLC.Inventor: William J. Edinger

Patent number: 5785834Abstract: An electrostatic filter utilizes two separate filter cartridges in a parallel flow configuration with respect to incoming dielectric fluid containing particulates. Each cartridge is connected to opposite sides of a high voltage power supply, resulting in the electrodes contained in one of the cartridges having an opposite polarity than the electrodes contained in the other cartridge. This, in turn, results in having the fluid borne particulates exiting one cartridge being charged oppositely to those exiting the other. The fluid streams exiting the two cartridges are joined together, allowing the particulates to flocculate. These larger groupings of particulates may then be mechanically filtered in a third cartridge. The parallel flow configuration results in an electrostatic filter that is relatively insensitive to water contained in the dielectric fluid.Type: GrantFiled: March 6, 1997Date of Patent: July 28, 1998Assignee: Contamco CorporationInventor: Donald E.
