Liquid Purification Or Separation > With Alarm, Indicator, Register, Recorder, Signal Or Inspection Means > Fluid Pressure Responsive Fluid Pressure ResponsiveFluid Pressure Responsive patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.01/24/08 - 20080017558 - Methods and devices for improved aeration from vertically-orientated submerged membranes Submerged gas diffuser assemblies configured to aerate liquid suspensions in reservoirs or deep shafts with enhanced aeration contact patterns and adjustable aeration rates. Aeration contact patterns and rates are varied by the adjusting the spatial configuration of gas permeable membranes, altering the fluid flow patterns around the membranes, manipulating trans-membrane ... 11/08/07 - 20070256963 - Plugged filter detection system A plugged filter detection system includes a valve housed within a cavity defining an initial inlet for receiving fluid at an inlet pressure before fluid enters a filter, a final inlet for receiving fluid at an outlet pressure after the fluid exits the filter, and a switch port for directing ... 10/25/07 - 20070246405 - Flushing agent conditioning device for a hard material-tipped cutting machine A flushing agent conditioning device (1) for a hard material-tipped cutting machine (2) includes a flushing agent circulation circuit that can be closed at least partially with respect to a hard material-tipped tool (4) which is to be flushed and that has a discharge trough (8) and flushing agent pump ... 10/18/07 - 20070241036 - Filter for filtering fuel A liquid filter (1) for filtering fuel or another liquid, including a filter element (9) disposed in a housing (2) and having at least one end cap (3, 4) formed by a section of the housing (2). The filter element (9) is embedded in the end cap (3, 4) or ... 08/23/07 - 20070193929 - Housing for environmentally friendly filter cartridge A filter system in which a housing and an environmentally friendly filter cartridge are coordinated to provide ease of change of the filter cartridge and reliable operation. The cartridge contains no metal parts and is readily incinerateable. The housing is provided with a number of “universality” features including a changeable ... 06/28/07 - 20070144949 - Method and apparatus for testing membrane integrity A portable or handheld testing apparatus for testing the integrity of membranes in a water treatment unit includes a pressurized gas supply element for pressurizing one side of membranes of a water treatment unit; a pressure sensor in communication with the gas on said one side of the membranes for ... 03/29/07 - 20070068855 - Liquid visual display A display provides indicates the remaining useful life of a filter element by providing a visible level of fluid in the display corresponding to the remaining useful life. The fluid level is adjusted by a valve responsive to a pressure differential across the filter element. An increasing pressure differential produces ... 03/15/07 - 20070056888 - Filter change indicator A filter change indicator includes two indicators visible through a window. The first indicator is disposed in the viewing window in a fixed position. The second indicator covers the first indicator in a first position and is moveable relative to the first indicator to a second position revealing the first ... 02/15/07 - 20070034555 - Fluid filter with pressure relief valve A fluid filter assembly having a relief valve for visually indicating when a filter element may be replaced. The fluid filter assembly of the present invention provides a vertical, transparent housing having a fluid inlet for communicating a fluid into the housing and a fluid outlet for communicating fluid downstream ... 07/13/06 - 20060151363 - Modular disc filter with integrated and automated self-flushing operator A filter module for a filter battery includes an outer wall that surrounds a chamber having inflow and outflow ends. An inner wall divides the chamber into a plurality of compartments including an inflow compartment, outflow compartment, bi-directional compartment and drain compartment. Each compartment extends from the inflow end to ... 04/20/06 - 20060081518 - Contaminated liquids filtering apparatus A filtering apparatus comprising an elongate container body, an inlet, an inlet reservoir, an outlet, an outlet reservoir, and at least two filter elements, wherein each filter units contains two or more space-apart and co-axially stacked filter elements encased in a cylindrical-shaped filter cartridge. Contaminated fluid flows from the inlet, ... 02/23/06 - 20060037894 - Particle filter for fuel cell coolant A particle filter for a fuel cell coolant is disclosed. The particle filter includes a filter housing having an upstream end for receiving the coolant and a downstream end for discharging the coolant. A filter element is provided in the filter housing. A pressure gauge is operably connected to the ... 07/28/05 - 20050161376 - Brine container with filter system Brine container, at which a suction filter (24) is disposed, in which the brine container has a circulating filter system (28), which has a filter (34) and a pump (30), with which the brine (22) can be pumped through the circulating filter system (28), the filter (34) having an exchangeable ... 06/09/05 - 20050121373 - Arrangement for filtering hydraulic fluid An arrangement for filtering a hydraulic fluid having a bypass line connecting the feed channel to the discharge channel where the bypass line is opened by a pressure switching valve when a pressure change is caused by the contamination of the filter element. ... ### FreshPatents.com Support - Terms & Conditions |
