  • Patent number: 9518912
    Abstract: Apparatus and methods determine a permeation characteristic of a challenge chemical for a chemical protective material. A processor retrieves barrier characteristics of the chemical protective material for which the permeation characteristic is to be determined from a computer memory. Information regarding the challenge chemical is obtained. A temperature is received of the chemical protective material for which the permeation characteristic is to be determined. The permeation characteristic is determined from the temperature, the barrier characteristics, and the information regarding the challenge chemical.

  • Patent number: 8806772
    Abstract: A grain drying system includes a master control unit external to the grain storage bin which is preprogrammed with a desirable grain moisture content or EMC. Condition sensor assemblies mounted within the grain bin determine the relative humidity and the temperature of the grain within the grain bin. Also, sensors mounted in the bin's plenum determine temperature, relative humidity and air pressure. A weather station mounted externally of the grain bin determines the outside air temperature and relative humidity. Depending on the conditions determined by the sensor assemblies and the weather station, the master control unit selectively activates the grain bin's drying fan when needed and when it is efficient and effective to do so. A radio or cellular modem allows for communication of the grain's condition. The internal sensor assemblies are preferably secured to flexible cables hung within the grain bin. The cable and rigid rod-like members support the sensors.

  • Publication number: 20110023317
    Abstract: A dryer felt tension indicator apparatus is disclosed for indicating a value which is proportional to a tension applied between a frame and a stretcher roll for guiding a dryer felt. The value is proportional to a tension of the dryer felt. The apparatus includes a carriage for rotatably supporting the stretcher roll. A wheel is rotatably secured to the carriage and a tensioner having a first and a second extremity cooperates with and extends around the wheel such that the wheel is disposed between the first and the second extremity of the tensioner. A tension indicator has a first and a second end. The first end of the tension indicator is anchored to the frame.

  • Publication number: 20100299954
    Abstract: A device for refreshing fabrics by reducing malodors and/or wrinkles without requiring that the fabrics to be put through an entire standard laundry process. The device comprises an extractable drawer which is pulled out of the device to allow for loading of a fabric into a receiving region. The extractable drawer can then be closed transporting the fabric into the interior of the device. A fabric treatment composition is sprayed or otherwise dispensed onto the fabrics when the device is operated. The device comprises an air flow path and a heating element which allows for the fabrics to be treated during use. The extractable drawer of the present invention can be positioned to extract laterally or vertically out of the shell of the device.

  • Publication number: 20100236091
    Abstract: In a sensor system for a domestic laundry dryer in which a canister-shaped condensate container 5 is mounted in a receiving chamber 15, at least one sensor S2 is used to monitor the insertion of the condensate container 5. Another sensor S1 takes over the detection of a limiting filling level 12 of the condensate in the condensate container 5. When this level is reached, emptying of the condensate container 5 is requested by switching an audible and/or visual attention signal. This container can be removed from the inside of the loading door 6. At least one sensor S2 is a non-contact switch. The sensor system contains a circuit arrangement which can be influenced by the sensor or sensors S for controlling the drying program of the laundry dryer. The sensor or sensors preferably S contain magnetically influencable switches. They form a switching system comprising a magnetically influencable switching contact 1 and a magnet 2.
