Publication number: 20240396154Abstract: A venting unit for a battery pack includes: a housing having a valve opening and a sealing lip around the valve opening; a first valve part; a stem, one end connected to the first valve part, an opposing end connected to a second valve part; and a spring between the housing and the second valve part. The first valve part has an opening portion with a planar part and a sloped part connected between the planar part and the stem. A gradient of the sloped part increases from the planar part toward the stem. In a closed state, the planar part of the opening portion and the sealing lip of the housing together seal a gap between the opening portion and the housing, and in an open state, the opening portion is spaced apart from the sealing lip against the spring.Type: ApplicationFiled: May 6, 2024Publication date: November 28, 2024Inventor: Paul KRAUS

Publication number: 20090150086Abstract: A use composition monitor determines the concentration of peracid and/or peroxide in a use composition using a kinetic assay procedure. A sample mixture containing a sample of the use composition, a diluent and at least one reagent is prepared and analyzed using, for example, an optical detector. Response data obtained by the detector is indicative of the optical absorbance of the sample mixture as a function of time. A processor analyzes the response data to determine a corresponding best fit linear relationship. Depending upon an expected concentration range, the initial absorbance and/or the slope of the best fit equation are used to calculate the concentrations of the peracid and peroxide in the use composition.Type: ApplicationFiled: February 12, 2009Publication date: June 11, 2009Applicant: ECOLAB INC.Inventors: Eugene Tokhtuev, Christopher Owen, Paul Kraus, Joseph Erickson, Paul Schilling, Daniel Kamben, William Christensen, Viktor Slobodyan

Publication number: 20080030712Abstract: An ultraviolet (UV) fluorometric sensor measures a chemical concentration in a sample based on the measured fluorescence of the sample. The sensor includes a controller, at least one UV light source, and at least one UV detector. The sensor emits UV light in a wavelength range of 245-265 nm from the light source through the sample in an analytical area. The UV detector measures the fluorescence emission from the sample.

Patent number: 7147095Abstract: A gearshift mechanism for a motor vehicle with hydraulically actuated multiple clutch, particularly a twin clutch, has a first gear input shaft to drive a first group of gears and a second gear input shaft to drive a second group of gears. The two gear input shafts are each assigned a clutch unit being coaxial to one another. A stationary housing accommodates the two clutch units. At its end face, the housing can be closed off by a housing cover that has a central opening through which a drive hub of a clutch cage is guided. The housing cover is provided with a bearing flange around the central opening, on the outside of which the clutch cage is supported. This advantageously supports the clutch on the housing and makes it possible to achieve a support effect for a dual mass flywheel or the crankshaft end of the internal combustion engine.Type: GrantFiled: March 26, 2003Date of Patent: December 12, 2006Assignees: Dr. Ing. h.c.F.
