Publication number: 20220250089Abstract: A sensor system for a sparger having a housing with an inlet configured to receive a flow of compressed gas for injection of bubbles into a flotation system. The sensor system comprises a flow measurement device in line with the inlet and a movable rod assembly within the housing. A sensor and a target that move relative to each other, wherein one of the sensor and the target is located in the housing the other is located on or attached to the movable rod assembly. The sensor for measuring parameters of motion, position, and vibration, relative to the target based on the movement of the movable rod assembly. The sensor system for determining operating parameters of the sparger based on analysis of the measured motion, position, and vibration of the sensor relative to the target and flow measurements from the flow measurement device.Type: ApplicationFiled: April 27, 2022Publication date: August 11, 2022Applicant: Eriez Manufacturing Co.Inventors: Michael J.

Patent number: 6644837Abstract: A surgical lighthead includes a reflector, a lens coupled to the reflector, and a handle located adjacent the lens. The handle defines an air passage to facilitate installation of a shield over the handle. A lamp assembly includes a support and at least one bulb located on the support between the reflector and the lens. Tubes are mounted in an interior region of the lighthead between the reflector and the lens, and rods are configured to engage the support. Each rod extends through the support and into a corresponding tube. The rods include at least one threaded portion configured to secure the lamp assembly within the interior region. The rods are slidable relative to the tubes upon disengagement of the threaded portions of the rods to permit the lamp assembly to move out of the interior region of the lighthead. The rods include stops to prevent separation of the lamp assembly from the lighthead. A controller turns the bulb on and off and adjusts the intensity level of light emitted from the bulb.Type: GrantFiled: March 11, 2002Date of Patent: November 11, 2003Assignee: Hill-Rom Services, Inc.Inventors: Richard L. Borders, Dennis C. Coon, Ronald P. Krahe, John M. Bulko

Patent number: 4687635Abstract: A steam sterilization cycle having a conditioning stage, a sterilizing stage, a drying stage and an air admission stage which provides maximum removal of entrapped air from full or partial porous loads. The conditioning stage includes a plurality of pressure/vacuum pulses. The final vacuum pulses are deeper than the initial pulses. The sterilizing stage includes a diffusion dwell come-up which gradually increases the temperature and pressure of the chamber to the predetermined sterilization temperature by a sequence of pressure rises followed by pressure plateaus which permit substantially complete steam penetration of the load and substantial equalization of the actual load temperature and the temperature sensed by the sterilizer controls and substantially eliminates superheating the chamber. The cycle may also include a step for detecting and reacting to unacceptable levels of noncondensable gas present in the chamber during the sterilization stage.Type: GrantFiled: October 5, 1984Date of Patent: August 18, 1987Assignee: American Sterilizer CompanyInventors: Kristine M. Kaehler, Ronald P. Krahe, Peter T. Miraldi, Richard A. McBride
