Title: Valve apparatus
Inventor: UPTON MARK E
IPC: F16K25/00
Filed: 2001-12-05
Granted: 2009-02-03
Abstract: A valve apparatus that has a longitudinal axis therethrough comprises a valve seat member, a valve closure member, a fluid flow path, and a screening member. The valve seat member comprises a hollow bore and a first frustoconical contact surface. The valve closure member comprises a body and a second frustoconical contact surface that is adapted to seal against the first frustoconical contact surface. The valve closure member is movable along the longitudinal axis of the valve apparatus. The fluid flow path extends through the bore of the valve seat member and between the valve seat member and the valve closure member. This fluid flow path is closed when the second frustoconical contact surface is sealed against the first frustoconical contact surface. The screening member is attached to at least one of the valve closure member or the valve seat member, and screens particles from fluid passing through the fluid flow path when the valve closure member approaches the valve seat member.

Title: Apparatus and method for ejecting sample well trays
Inventor: BORDENKIRCHER GARY L
IPC: B01L3/00
Filed: 2001-02-01
Granted: 2005-12-27
Abstract: The invention includes a heating apparatus for biological samples. The heating apparatus of the present invention includes a cover, a sample block having a plurality of openings in a top portion thereof for receiving a sample well tray having a plurality of sample wells, and an urging mechanism. The urging mechanism is positionable between the sample block and the sample well tray to urge the sample well tray away from the sample block when the cover is moved from a closed position toward an open position. The cover imparts a downward force on the top of the sample well tray to press the sample wells into the openings of the sample block when the heated cover is moved toward a closed position.   The urging mechanism imparts an upward force on the sample well tray.      The downward force imparted by the heated cover is sufficient to retain the sample well tray against the sample block when the cover is in the closed position.

Abstract: The current differential relay operates without adjustable settings, and includes a phase current differential element with a predetermined threshold, responsive to local phase current values and remote phase current values, to detect three- phase faults and producing a first output signal if the threshold value is exceeded. Either a negative sequence current differential element or two phase current differential elements, also having predetermined threshold values and responsive to the local and remote phase currents, detect phase-to-phase faults and phase-to- phase-to-ground faults and produces a second output signal if the predetermined threshold is exceeded. A negative sequence or zero sequence current differential current element, with a predetermined threshold value is responsive to the local and remote phase currents to detect phase-to-ground faults and to produce a third output signal if the threshold is exceeded. If any one of the first, second and third output signals occurs, a trip signal is generated and directed to the associated circuit breaker. The thresholds are selected to permit use of the relay in a wide range of possible applications.

Title: Electrochemical cell with gas diffusion electrodes
Inventor: FAITA GIUSEPPE
IPC: C25B9/23
Filed: 2002-11-12
Granted: 2011-07-12
Abstract: A membrane electrolysis cell comprising an anodic compartment and a cathodic compartment is described, wherein at least one of the two compartments contains an electrode fed with gas and a porous planar element is interposed between the membrane and the gas-fed electrode. A flow of chemically aggressive electrolyte crosses the porous planar element downwards under the effect of the gravity force. The planar element consists in a plastic element withstanding the aggressive operative conditions: The use of perfluorinated plastics such as ECTFE, PTEFE, FEP, PFA is preferred, even though they are strongly hydrophobic. When the gas-fed electrode is a cathode and the gas contains oxygen, the gas crosses the cathodic compartment upwardly so as to minimise the risk of hydrogen build up. The cell equipped with the oxygen cathode is particularly advantageous for the sodium chloride electrolysis.
