Publication number: 20130180900Abstract: An oil spill cleanup device is described. The device includes a container and at least one flexible hollow elongated member extending from the container. The device floats in water and can be used to collect and separate oil from the contaminated water. Water is collected by the elongated member, which has several exterior one-way valves that allow contaminated water to enter the member. The contaminated water is pushed towards and into the container by the wave motions of the surrounding water. The elongated member has internal one-way valves that help to direct the contaminated water towards the container. Once in the container, the contaminated water can separate into water and oil due to differences in specific gravity. Multiple devices can be connected together to form a barrier for containing the contaminated water within a limited area.Type: ApplicationFiled: January 13, 2012Publication date: July 18, 2013Applicant: Fluor Technologies CorporationInventor: Gary J.

Patent number: 8480882Abstract: The present invention is a water filter pitcher equipped with a removable, replaceable filter cartridge and means to count the number of times the pitcher is filled with water, and also means to notify the user when the pitcher has filtered enough water to exhaust the filtering capacity of the filter cartridge so that the user can replace the filter cartridge when necessary but does not have to remember to change the cartridge at a specific interval or count the number of gallons filtered manually, and instead can rely on the water filter pitcher to track the amount of water filtered and inform the user when to change the filter cartridge.Type: GrantFiled: June 1, 2010Date of Patent: July 9, 2013Assignee: Protect Plus LLCInventors: Glenn Cueman, Bob Beckmann

Publication number: 20130168302Abstract: A hot-water supply system includes a switching valve (35) which has a bypass circuit which bypasses the water softening device (30) by directly connecting the water supply pipe (P1) and the inlet pipe (P3) of a hot-water supply device to each other, and a control unit (50). The control unit (50) includes a switching valve drive circuit which switches the switching valve (35) to the mode in which water is supplied from the water supply pipe (P1) to the hot-water supply device (1) via the bypass circuit, based on the determination of the timing of salt replenishment, and a display drive circuit which displays intention, in which salt replenishment is needed, on a display portion (51) of a remote controller (RC).Type: ApplicationFiled: October 22, 2010Publication date: July 4, 2013Applicant: RINNAI CORPORATIONInventor: Fumio Ogai

Publication number: 20130161242Abstract: A seal is brought into contact with a filter media, a filter pump is operated to start filtration, and a signal from a pressure sensor is received. When a predetermined value is exceeded by the signal from the pressure sensor, the filter pump is stopped, the seal is separated from the filter media, and take-up of one section of the filter by a filter collection roll is started. In finishing filter supply from a filter supply roll, drive of a motor is stopped, and an alarm signal is transmitted. If the supply is not to be finished, one section of the filter is taken up by the filter collection roll, and the next stage of filtration is entered.Type: ApplicationFiled: September 13, 2012Publication date: June 27, 2013Applicant: FANUC CORPORATIONInventor: Hirotsugu KASAI

Publication number: 20130161265Abstract: Disclosed are systems and methods for monitoring and controlling a real-time oxidation-reduction potential in a hot water system to inhibit corrosion in the hot water system. The method includes defining one or more operational protective zones in the hot water system. One or more of the operational protective zones includes an oxidation-reduction potential probe that is operable to measure a real-time oxidation-reduction potential in the hot water system at operating temperature and pressure. The probe transmits the measured real-time potential to the controller, which assesses and interprets the transmitted potential to determine whether it conforms to an oxidation-reduction potential setting. If the measured potential does not conform the oxidation-reduction potential setting, the controller is operable to feed or remove one or more active chemical species into or from the hot water system and further operable to change at least one system parameter.Type: ApplicationFiled: February 21, 2013Publication date: June 27, 2013Applicant: NALCO COMPANYInventor: NALCO COMPANY
