Publication number: 20240094233Abstract: The present invention relates to methods, devices and systems for associating consumable data with an assay consumable used in a biological assay. Provided are assay systems and associated consumables, wherein the assay system adjusts one or more steps of an assay protocol based on consumable data specific for that consumable. Various types of consumable data are described, as well as methods of using such data in the conduct of an assay by an assay system. The present invention also relates to consumables (e.g., kits and reagent containers), software, data deployable bundles, computer-readable media, loading carts, instruments, systems, and methods, for performing automated biological assays.Type: ApplicationFiled: July 18, 2023Publication date: March 21, 2024Inventors: Jacob N.

Patent number: 8057192Abstract: A condensate pump includes a condensate reservoir, a liquid level float sensor operable to sense a liquid level within the condensate reservoir, and a pressure/vent valve including a pressure source, a pressure vent, and a primary piston slidably supported in a primary cylinder and sliding in the primary cylinder responsive to the liquid level sensor. A secondary piston is slidably supported in a secondary cylinder and moves responsive to a movement of the primary piston between a first secondary-piston position wherein the pressure source is in communication with a gas space of the condensate reservoir and the pressure vent is isolated from the gas space, and a second secondary-piston position wherein the pressure source is isolated from the gas space and the pressure vent is in communication with the gas space. An aperture in the primary piston and passages may also be provided to prevent build-up of gas pressures and maintain pressures in preselected regions within the pump at atmospheric pressures.Type: GrantFiled: January 30, 2009Date of Patent: November 15, 2011Assignee: Spence Engineering Company, Inc.Inventors: George W. Page, Jr., Dan Walter Cole

Patent number: 6220519Abstract: A thermostatic steam trap for use in sanitary environments has a steam trap body defining a steam trap cavity and consisting of an inlet body portion defining an inlet port in communication with an inlet cavity portion and an outlet body portion defining an outlet port in communication with an outlet cavity portion. The inlet and outlet cavity portions are disposed in communication to define the steam trap cavity. A centering member is disposed generally between the inlet and outlet body portions. A thermostatic bellows/plug assembly mounted to the centering member moves within the steam trap cavity between a first position in engagement with a seat defined by the steam trap body, thereby to resist flow of fluid between the steam trap cavity and the outlet port, and a second position spaced from engagement with the seat, thereby to permit flow of fluid between the steam trap cavity and the outlet port.Type: GrantFiled: November 1, 1999Date of Patent: April 24, 2001Assignee: Watts Investment CompanyInventors: George W.

Patent number: 5315819Abstract: A power management system for turbine engines includes a plurality of switches, each allowing for engine speed and engine torque to be controlled together. The switches correspond to various modes of operation of the turbine engine. When a switch is selected, a mode signal is supplied to a FADEC which, in response, issues speed and torque commands to an associated engine. The FADEC includes function generators that issue the torque commands as a function of outside ambient conditions. The torque commands are continuously updated for changing ambient conditions. Further, takeoff torque can be corrected for heating conditions. The power management system can also provide torque commands as a linear function of power lever angle.Type: GrantFiled: September 17, 1991Date of Patent: May 31, 1994Assignee: Allied-Signal Inc.Inventors: George W.

Patent number: 5299417Abstract: An aircraft is maintained at a constant glide slope and air speed by trimming delta torque commands provided by an autopilot. Delta torque commands that change by more than twenty percent are trimmed automatically to maintain the constant glide angle and to assist the pilot in maintaining air speed within .+-.5 knots on the approach glide slope.Type: GrantFiled: September 18, 1991Date of Patent: April 5, 1994Assignee: Allied-Signal Inc.Inventors: George W.

Patent number: 5165240Abstract: Disclosed herein is a method of matching engine torques in a power management system having a digital engine control for each of multiple turbine engines. Input data is selected from one source such that each digital engine control utilizes the same set of input data to generate torque commands. As a result, engine torques can be matched to within one percent.Type: GrantFiled: September 18, 1991Date of Patent: November 24, 1992Assignee: Allied-Signal Inc.Inventors: George W. Page, Glen T. High, Larry C. Prevallet, Joseph W. Free
