Patent number: 7516905Abstract: A power control system for automatically and proportionately metering power to a heating device used to create a warm microenvironment conducive to the health and growth of an animal during a predetermined incubation period is herein disclosed. The power control system transmits proportionally more power to a heating device where an ambient room temperature measured outside of the microenvironment is nearer a predetermined lower limit, and proportionately less power when the ambient room temperature measured outside of the microenvironment is nearer a predetermined upper limit. A method of providing a heated microenvironment within a larger environment also is disclosed.Type: GrantFiled: September 27, 2005Date of Patent: April 14, 2009Assignee: Novonix CorporationInventors: Mark H. Jaeger, Thomas K. Hiniker, Michael W. Lundgreen

Patent number: 7021552Abstract: The invention relates to a method for controlling the temperature in a controlled-climate chamber, wherein: an organism, such as a plant or an animal, is placed in the controlled-climate chamber; the temperature in the controlled-climate chamber is kept essentially constant at a specific value (T1); at least one growth characteristic (G) of the organism, such as, for example, the CO2 production, is measured; the temperature in the controlled-climate chamber is raised or lowered by a specific value (?T); the magnitude of the growth characteristic is measured again; the variation in the measured value of the growth characteristic is determined (?G); and the temperature in the controlled-climate chamber is adjusted, depending on the variation in the measured value of the growth characteristic (?G) that has been determined.Type: GrantFiled: November 19, 2001Date of Patent: April 4, 2006Assignee: HatchTech Group B.V.Inventor: Tjitze Meter

Patent number: 5573179Abstract: A method for controlling environmental conditions or variables to which living organisms are exposed employs time integrated variables (TIVs) to assist in controlling the conditions. In one example, temperature in a poultry house is controlled, in part, according to a 24 hour time integrated average temperature value. Since it has been established that poultry is more sensitive to a 24 hour time integrated average temperature than to a particular instantaneous temperature, a temperature control strategy based upon the 24 hour time integrated average temperature can result in optimum performance of the poultry resulting in a substantial economic benefit. Further, in some instances the instantaneous temperature may be allowed to fluctuate over a wider range of temperatures, as long as the time integrated average temperature value is maintained within a desired range, and this can provide additional economic benefit from reduced operating expenses of the environmental control system.Type: GrantFiled: September 9, 1994Date of Patent: November 12, 1996Assignee: Cornell Research Foundation, Inc.Inventors: Michael B. Timmons, Richard S. Gates

Patent number: 4171770Abstract: A poultry raising system includes a house having one or more enclosed sections with at least one section provided with a plurality of hovers and all of the sections having peripheral heat assemblies. All hovers and heat assemblies are equipped with sealed heat radiating conduits supplied with a fluid heat transfer medium from a common heating apparatus. A supply and return line serving each section from the heating apparatus includes a thermostatically-controlled valve admitting the heat transfer medium to all of a section's hovers as well as other thermostatically controlled valves regulating the flow of heat transfer medium to each of a section's peripheral heat assemblies. Dampers in roof-top vents are automatically opened and closed in response to signals from a gas sensor in each section to evacuate obnoxious gasses from each section enclosure and the evacuated gas is replaced by fresh outside air admitted through automatic dampers adjacent the house side walls.Type: GrantFiled: July 17, 1978Date of Patent: October 23, 1979Inventor: John H. Mailander, Sr.

Patent number: 4164869Abstract: A receiver of thermal radiation of thin film deposit material of high temperature coefficient of electrical resistance having surface absorptive characteristics.Type: GrantFiled: September 12, 1977Date of Patent: August 21, 1979Inventor: Theodor H. Benzinger

Patent number: 3976243Abstract: A gas fuel supply control system for a plurality of poultry brooders arranged in a series and each having a gas fired main burner. The control system includes an electrically activated main gas regulating valve device electrically controlled by electrical signals from a thermostatic switch to open and close it at predetermined temperature levels, and regulate the gas fuel supply through a main burner manifold to all of the brooder main burners. A non-electrical self-operating hydraulic snap valve device having a temperature sensing fluid which directly effects valve opening and closing forms a bypass around the electrically activated regulating valve device and is set to operate at a slightly lower temperature to take over automatic control of the gas supply to the manifold during electrical power failure disabling the electrically activated valve.Type: GrantFiled: June 10, 1975Date of Patent: August 24, 1976Assignee: Shenandoah Manufacturing Co. Inc.Inventor: Reuben L. Christophel
