Abstract: Disclosed is a clothes dryer. The clothes dryer includes a drum; an air supply/exhaust unit for supplying/exhausting drying air to/from the drum; a burner for heating the drying air; a temperature sensor for detecting an exhaust temperature; and a heating control unit for performing a temperature adjustment process of stopping the burner when the exhaust temperature reaches an upper limit temperature and restarting the burner after a time point when the exhaust temperature decreases to a re-ignition temperature. The heating control unit has a delay time inserting portion, which inserts a delay time between the time when the exhaust temperature decreases to a lower limit temperature and the time when the burner is restarted. The delay time is increased every time the temperature adjustment process is repeated intermittently.

Abstract: A device for determining the conductance of laundry in a drier. The device comprises at least two electrodes and means for dissipating heat from at least one part of at least one of said electrodes. The invention further relates to a drier comprising at least one area for receiving laundry and at least two electrodes for measuring the conductance of the laundry, at least one of the electrodes at least partly bordering said receiving area. Means for cooling at least one part of at least one of the electrodes are also provided inside the drier. Also disclosed is a method for preventing the formation of layers on electrodes used for measuring conductance in a drier.

Abstract: A master generator that updates time data of remote devices comprises an acquisition module, a clock module, an encoding module, and a transmission module. The acquisition module acquires time data representing current time of day. The clock module receives and stores the time data from the acquisition module and periodically updates the time data. The encoding module encodes the time data from the clock module into time messages. The transmission module selectively superimposes the time messages onto a power signal.

Abstract: The disclosure provides an apparatus for controlling the rate of heat transfer from as-cast railroad wheels after their removal from the mold utilizing a plurality of vertically adjustable caps with a cap positioned over each wheel to control the rate of heat transfer therefrom as it is transported to a successive operation, each cap having a generally symmetrical shape to inhibit or reduce deflection of radiant energy from the wheel, and the disclosure also provides a method for controlling the rate of heat transfer including a control system to provide the requisite displacement of each cap from the associated wheel to control cooling of the wheel prior to its subsequent operation.

Abstract: A dryer is disclosed in a compact design for interstation use on printing presses, particularly lithographic presses. High velocity air is combined with intense infrared radiation to heat, evaporate and scrub vapor from freshly printed substrates. Air under pressure is provided through passages in a housing which is passed toward and by the infrared lamp in such a way as to cool the lamp and thereafter impact the substrate being dried. A pressure sensing control prevents operation of the lamp without the cooling air. The lamp power circuit is switched off if air pressure is lost. The dryer is mounted in an extractor housing provided with a negative pressure to extract the supplied air after it impacts upon the substrate.
