Patent number: 6715216Abstract: A clothes dryer is provided with a fire detection and suppression system which releases a fire suppressing substance into the dryer chamber upon detection of a fire condition. The fire detection and suppression system includes, a controller, at least one temperature detector which is in communication with the controller and sends a signal to the controller when a temperature set point has been reached and/or exceeded, a source of fire suppressing substance (preferably water) which is delivered to the chamber over a pathway; and a valve in the pathway controlled by the controller. The controller opens the valve when a fire condition is detected, and closes the valve after a time sufficient to introduce a predetermined volume of the fire suppressing substance has passed.Type: GrantFiled: July 11, 2003Date of Patent: April 6, 2004Assignee: Cissell Manufacturing CompanyInventors: Naom Salameh, Stanley T.

Patent number: 6619215Abstract: An incinerator includes a furnace, a heat-insulating shield, an air conduit, an air blower, and a dryer. The heat-insulating shield has a top wall, a vertically extending peripheral wall that extends downwardly from the top wall and that surrounds and that is spaced apart from the furnace by a gap, and an open bottom end. The peripheral wall of the heat-insulating shield has an air outlet that is disposed adjacent to the top wall and that is in fluid communication with the gap. Atmospheric air is introduced via the open bottom end through the gap and the air conduit and into the dryer.Type: GrantFiled: April 24, 2002Date of Patent: September 16, 2003Inventor: Dai-You Lin

Patent number: 6560897Abstract: Improved spray drying apparati, and methods of use thereof, have been developed. The spray drying equipment includes a primary drying chamber and a secondary drying apparatus which includes tubing having a length sufficient to increase the contact time between the drying gas and the droplets/particles to dry the particles to the extent desired, at a drying rate and temperature which would be too low to provide adequate drying without the secondary drying apparatus. The secondary drying apparatus increases the drying efficiency of the spray dryer system without increasing the drying rate, while minimizing loss in yield. Te secondary drying apparatus can include multiple secondary apparati, which are independently controlled for temperature and/or have different dimensions (cross-sectional areas and/or lengths), to allow for optimization of drying conditions.Type: GrantFiled: October 26, 2001Date of Patent: May 13, 2003Assignee: Acusphere, Inc.Inventors: Donald E.

Patent number: 6519871Abstract: A method and apparatus for operating an automatic cycle of a clothes dryer wherein after initiation of an automatic cycle, a CPU displays the expected time remaining during the current cycle. At various times during the cycle, the expected time remaining is updated by comparing the time required to reach certain moisture levels of the articles contained therein to reference times. The comparison also results in the expected times being updated for future uses of the clothes dryer. Finally, the invention includes a system for updating the amount of time required to reach a desired final temperature during a cooldown sequence.Type: GrantFiled: May 25, 2001Date of Patent: February 18, 2003Assignee: Maytag CorporationInventors: Douglas W.

Patent number: 5611935Abstract: A method for treating sludge by dewatering to form thick sludge and drying to form dry sludge includes the steps of mechanically predewatering thick sludge to produce predewatered thick sludge and mixing the predewatered thick sludge with non-cooled dry sludge to produce a sludge mixture. The temperature of the sludge mixture to be dried is measured and the dry substance contents of the dry sludge based on the measured temperature is determined. Fluctuations in the dry substance contents of the dry sludge are compensated by controlling the amount of recirculated dry sludge to be mixed with the predewatered thick sludge as a function of the temperature of the sludge mixture to be dried. The sludge mixture is dried to produce dry sludge and a portion of the dry sludge is recirculated to be mixed with the predewatered thick sludge.Type: GrantFiled: August 18, 1995Date of Patent: March 18, 1997Assignee: Steag AktiengesellschaftInventors: Heinz Thiemann, Helmut Brauweiler, Ivan Rupert, J org Bublies, Burkhard M oller

Patent number: 5410230Abstract: A system for conditioning air in a space by heating or cooling the air to change its temperature. A thermostat located within the space generates a two state temperature signal having a cyclic parameter which corresponds to the temperature of the air in the space as it rises and falls. A compressor supplies refrigerant to a heat exchanger by means of which changes are made in the temperature of the air. A variable speed motor drives the compressor in response to a motor control signal. A controller responds to the temperature signal and senses the cyclic parameter of the temperature signal. The controller generates the motor control signal as a function of the sensed cyclic parameter whereby the motor control signal is provided to the motor to control the torque or speed of the motor.Type: GrantFiled: March 2, 1993Date of Patent: April 25, 1995Assignee: General Electric CompanyInventors: Warren F. Bessler, John M. Hooker, Rajendra K. Shah
