Abstract: A dryer with an improved arrangement of heating coils is provided. The improved heater assembly includes a heater case partitioned into an upper passage and a lower passage, with independent first and second coil arrays crossing the plate between the upper and lower passages. The first and second coil arrays may be separately controlled to adjust an amount of drying capacity provided to the dryer while maintaining a uniform flow of drying air.

Abstract: A livestock cooling system creates an environment for protecting the health and productivity of animals, particularly dairy cows. One or more cooling fans are connected to programmable oscillation means, enabling the herds man to program fan oscillation according to the location of the livestock. Water is injected under high pressure into the air stream of the fans to create a fog. The system is also programmable according to various environmental conditions, including temperature, humidity, and wind velocity. The pressure and volume of the injected water are programmable and may be adjusted by the controller according to the observed environmental conditions. The disclosed system provides a cool and healthy environment for livestock, where the environment is programmed to track the animals according to the time of day, location of the animals and the location of shade.

Abstract: This invention is about portable mini clothes and hair dryer which is designed to collapse and fit into a standard suitcase. It possesses all the features of the standard clothes dryer but is approximately one tenth the size and weighs less than 25 pounds. The dryer will not operate in its collapsed state or if the lid is opened. It comprises a simple but reliable heater and motor assembly. The single flat motor drives both the blower fan and the rotating drum of the machine but the rotating drum can be disengaged when the unit is used for drying hair only. Clothes and other items can be packed in and around the dryer when traveling.

Abstract: A cabinet for clothes drying and dewrinkling which comprises a main enclosure that defines an inner area for housing clothes, a fan for supplying air to the inner area, a steam generator for supplying steam to the inner area, a controller for regulating the air supply and steam supply, and at least one airing duct. The airing duct can be opened and closed by the controller.

Abstract: A hand dryer timer having a switch in electrical communication with, and controlling the operation of a heater, a fan motor and a timer motor which are electrically connected to two nonneutral lines of a power source. A cam is mounted on a drive shaft of the timer motor such that the cam rotates with the drive shaft and also slides longitudinally over the drive shaft. The cam has a cam lobe adjacent an actuating arm of the switch. A biasing element is located between the timer motor and the cam and biases the cam to a first position aligning the cam lobe with the actuating arm of the switch. The switch includes two sets of switch contacts in a power circuit for the heater and fan motor, so that at the end of a drying cycle, the two sets of switch contacts are effective to electrically isolate the heater and fan motor from both non-neutral lines of the power source.

Abstract: A hybrid control for a clothes dryer which combines an electromechanical timer and a microprocessor. The electromechanical timer has a plurality of switches connected to a plurality of input ports of the microprocessor. The timer switches are driven by a plurality of cams such that the plurality of switches open and close in response to the cams at predetermined angular positions of the timer. In this manner, the switches provide control input to the electronic circuit for initiating the dry cycle and further provide control input to the electronic circuit during the dry cycle such that the electromechanical timer and the electronic circuit operate together to control the dryer operation. In addition, a sensor supplies a signal to the microprocessor corresponding to the moisture level of the clothes within the drum.
