  • Patent number: 6751885
    Abstract: Trays are provided with identical vertical spacers which enable the trays to be stacked on top of each other in a centered way, with a suitable or appropriate spacing between them, and enable the various adjacent stacks of trays to be raised and lowered in steps, by an elevating and lowering system which acts only on the bottom tray of each stack. The sides of the stacks of trays of the kiln are thus free and can be engaged by conveyors for the translation of the trays between the stacks, both in a normal operating cycle and in a short operating cycle. However, the lower translation conveyors, which transfer the trays from the stack with an unloading station to that with a loading station, are positioned in the conventional way, i.e., under the stacks of trays and transversely with respect to the trays.

  • Patent number: 5190201
    Abstract: A method and apparatus for reliably detecting the occurrence of a web break in a web processing system is disclosed employing a non-contacting, non-optical sensor to detect the presence of the web. Cushion pressure in a cushion pressure zone adjacent the web is sensed to determine a web break condition. A sensor block is mounted within an enclosure through which the web passes. The sensor block is configured to sense the cushion pressure in the region between an air bar and the web. The cushion pressure is communicated outside the enclosure to a transducer which compares the cushion pressure to either the internal ambient pressure of the enclosure or to atmospheric pressure. The resulting differential pressure is compared to a threshold differential; if the measured differential pressure drops below the predetermined threshold pressure, a web break is indicated and web processing is terminated.

  • Patent number: 5097606
    Abstract: A microprocessor controlled clothes dryer wherein the posture of a switch in the lint filter system is monitored and a signal to CHECK FILTER is displayed if the switch posture has not changed. The switched is a reed switch mounted stationary on the lint filter assembly and a magnet operator is attached to the removable filter screen. Movement of the filter screen into and out of filtering position in the lint filter assembly of the exhaust duct changes the posture of the magnet operated reed switch. Change of posture of the switch through its cycle impresses a change of voltage on the microprocessor. The microprocessor effects control over the CHECK FILTER signal that is visually illuminated on a VFD tube; such that, if the microprocessor sees the cycling of the switch the CHECK FILTER signal is extinguished.
