  • Patent number: 6440270
    Abstract: In controlling the dryer section of a paper machine, the basis weight and moisture of the paper web, the energy fed into the drying cylinders of the dryer section and the machine speed are measured, and then the surface temperature of the drying cylinders is predicted on the basis of the measured values. At the same time, the actual surface temperature of the dryer cylinders is also measured, and if the measured value deviates from the predicted value, any defects in the drying apparatus can be detected quickly. In another aspect, a determination is made of the normal correlation between the power consumption of the drive motors of the cylinders in the drying apparatus and the machine speed. These variables are also measured, and if the correlation of the variables is deviant, it can be concluded that there is a failure in the drying apparatus. In that case it is possible to identify the dryer cylinder where the failure is by measuring the temperature of the cylinders.

    Abstract: Liquid is removed from batches of substrates by apparatus and methods for drying substrates that have been wet in an elongated liquid bath. The substrates are moved relative to the bath and an elongated gas-filled volume at rates of movement selected according to the location of the batches of substrates in the bath or the volume. As an example, the substrates and the bath are separated at a controlled rate to form a thin layer of liquid on each substrate as each substrate enters the gas-filled volume. The gas-filled volume is defined by an elongated hot chamber and hot gas directed into the volume and across the substrates and out of the volume continuously transfers thermal energy to the substrates. The flow rate of the gas into the volume is related to introduction of the substrates into the bath to avoid disturbing the liquid in the bath.

  • Patent number: 6216362
    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.

  • Patent number: 6154978
    Abstract: A method and apparatus for confirming the initial conditions of a clothes dryer prior to the start of the drying cycle is provided. The clothes dryer comprises a drying chamber with air inlet and outlet ports. A blower powered by a first motor is arranged in the outlet port to draw air into the drying chamber through the inlet port. A burner for heating the air before it enters the drying chamber is arranged in the inlet port. Also arranged at the inlet port is an air proving device for measuring the air flow through the drying chamber. A second motor is provided for the drive system which creates the tumbling action in the drying chamber. The air flow proving device must be enabled before the second motor is started.

  • Patent number: 5873182
    Abstract: A real-time process and apparatus for controlling conditions in a lumber drying kiln include measuring the shrinkage of a sample of the lumber across the longitudinal axis of the lumber and over time. A slope of the curve is analyzed and can be used to determine when a stress peak and stress reversal occurs in the lumber sample. The detection of the stress peak indicates that the drying schedule of the kiln should be incremented to the next drying step. According to the invention, the schedule is incremented in the fastest possible way without degrading the quality of the lumber.

  • Patent number: 5852881
    Abstract: The inventive clothes dryer is provided with a system for preventing the overheating of the clothes in the drum caused by the abnormality in the V-belt, such as the break or derailment thereof. By the system, the power supply to the motor is halted temporarily while the motor is rotated at a predetermined speed, whereafter the motor keeps rotating due to its inertia. During the inertial rotation of a predetermined period of time, the number of rotations of the motor is counted. When the V-belt is in the normal state, the motor is loaded appropriately, so that the speed of the motor falls rapidly during the inertial rotation, and the number of rotations is accordingly small. When, on the other hand, the V-belt is in an abnormal state, the number of rotations is large. Therefore, the state of the V-belt is checked by comparing the number of rotations to a predetermined value, and when the number is smaller than the predetermined value, the drying operation is stopped.

  • Patent number: 5842288
    Abstract: A solid state alarm for a clothes dryer receives a line voltage signal prior to termination of the tumbling cycle to provide a series of pulses with decaying amplitudes driving a piezoelectric-type transducer. A timer terminating the series of pulses communicates with a pulse generating oscillator so as to eliminate partial pulsing at the conclusion of the alarm signal.

  • Patent number: 5782012
    Abstract: In a wrinkle release arrangement for a dryer, a heater heats articles to be wrinkle released, and a timer times the heating of the articles. The timer establishes a wrinkle out cycle. A temperature sensor senses a temperature related to a temperature of the articles. A control circuit substantially alternately energizes the heater and the timer in response to the temperature sensor in order to provide automatic wrinkle release responsive to load.

  • Patent number: 5743023
    Abstract: Control of temperature of the shelves in a freeze dryer compartment is achieved by circulating a cooled heat transfer fluid from a heat exchanger through a vacuum condenser independently of circulating the cooled heat transfer fluid either directly through the passageway chambers in the freeze dryer shelves, for cooling the shelves, or through a heater for heating the shelves. These circulations are effected by the selective control of electrically operated valves in fluid conduits automatically by a programmed computer.

  • Patent number: 5592754
    Abstract: An electronically controlled compressed air system (10) includes an air dryer (16) which dries compressed air before the compressed air is communicated to a reservoir (26). The air dryer (16) includes a desiccant (18) which is purged by using air stored in the reservoir (26). A pressure transducer (13) is installed on the reservoir (26) and transits an electrical signal, indicative of the pressure in the reservoir (26) to an electric controller (11). Electric controller (11) transmits signals at various selected pressure levels to solenoid value (28) to control loading and unloading of the compressor (12), to solenoid valve (36) to control purging of the air dryer (16), and to the warning light (40) to alert an operator of a low air pressure condition.

  • Patent number: 5570517
    Abstract: An improved slurry dryer of the type having a plurality of beater blades carried on a rotating shaft in a cylindrical housing, the improvement in combination therewith of a plurality of scraper blades mounted on at least one disk carried by the rotating shaft at the inlet end of the dryer for scraping the cylindrical side wall and the end wall to prevent the material entering the dryer from adhering and remaining on the side and end wall of the cylindrical housing. The scraper blades are replaceable and adjustable with respect to the side and end walls of the housing by slotted mounting to accommodate wear of the scraper blades. An air dam in the form of a radially extending disk is provided downstream of the scraper blade disks to direct drying air radially outward to impinge on the slurry material to be dried.
