Automatic Calibrating Electrically Controlled Diaphragm Valve Actuators And Methods For Their Calibration
US Patent:
5711507, Jan 27, 1998
Filed:
Oct 3, 1995
Appl. No.:
8/538785
Inventors:
Mark D. Berget - Onalaska WI
Dennis L. Manthei - West Salem WI
Dennis L. Manthei - West Salem WI
Assignee:
Gas Research Institute - Chicago IL
International Classification:
F16K 3104
US Classification:
25112904
Abstract:
An automatically-calibrating electrically-controlled diaphragm valve actuator has a stepper motor controlled by a controller mechanism for moving the actuator within a diaphragm valve. A reference position indicator is provided to signal the controller mechanism when the valve actuator is at a reference position within the actuator's linear stroke. A method for automatically calibrating an electrically controlled diaphragm valve actuator includes the following steps. The actuator is initially driven to a reference position. Second, the actuator is driven a first number of steps. Third, the actuator is returned to the reference position. Fourth, it is determined whether fall back has occurred. Fifth, a second number of steps is determined based upon whether fall back has occurred. Sixth, the actuator is driven the second number of steps in order to compensate for the fall back.

Concentration Control In An Absorption Chiller
US Patent:
5586447, Dec 24, 1996
Filed:
Jul 20, 1994
Appl. No.:
8/278539
Inventors:
Lee L. Sibik - Onalaska WI
Mark D. Berget - Onalaska WI
Mark D. Berget - Onalaska WI
Assignee:
Gas Research Institute - Chicago IL
International Classification:
F25B 1506
US Classification:
62141
Abstract:
A process for controlling an absorbent-refrigerant solution concentration in an absorption cooling system to prevent crystallization of the solution in which the crystallization temperature of the absorbent-refrigerant solution is calculated and the temperature of an absorbent-enriched solution, or strong solution, from the absorption unit heat exchanger is measured. Based upon the crystallization temperature and the measured absorbent-enriched solution temperature, the concentration of the absorbent is calculated using an iteration algorithm. Based upon the calculated concentration of absorbent in the absorbent-enriched solution, the concentration of the absorbent-enriched solution is adjusted by adjusting the heat input to the absorption system generator to prevent crystallization of the absorbent.
Crytallization Detection And Recovery For Two-Stage Absorption Refrigeration Machine
US Patent:
5813241, Sep 29, 1998
Filed:
Mar 24, 1997
Appl. No.:
8/823084
Inventors:
Lee Sibik - Onalaska WI
Mark Berget - Onalaska WI
Mark Berget - Onalaska WI
Assignee:
Gas Research Institute - Chicago IL
International Classification:
F25B 1500
US Classification:
62148
Abstract:
A crystallization detection and recovery method for a two-stage absorption refrigeration machine is provided. Crystallization in the low temperature heat exchanger is detected through temperature comparisons between certain absorbent solution flows. The recovery sequence includes steps to remove crystallization and to prevent subsequent occurrences.
