  • Publication number: 20100021765
    Abstract: This invention relates to a thermoplastic polymer composition that exhibits excellent characteristics for being thermoformed into a wide variety of packaging trays for electronics, including the disk drive and semiconductor industries. More specifically, these trays are applicable as packaging material for head suspension assembly and offer conductivities in the range of antistatic to electrostatic dissipation (ESD). For instance, the thermoplastic polymer composition of this invention offers improved stiffness, improved chemical resistance, the capable of enduring more washing cycles, the capability of being dried at higher temperatures, improved cleanliness, and better electrical conductivity that conventional PETG/IDP polymer blends.

  • Patent number: 5183646
    Abstract: A device for oxidizing gaseous materials, comprising a combustion chamber, wherein the device and the combustion chamber both have a top and a bottom, the device further having a gas outlet and being adapted to operate in conjunction with means applying negative pressure to the outlet, means for introducing process gas and a source of fuel into the top of the combustion chamber, means for effecting heat exchange between oxygen-containing gas and the combustion chamber to preheat the oxygen-containing gas, means for introducing the preheated gas into the top of the combustion chamber, means for mixing the preheated gas with the process gas and fuel so that the mixture can burn in the combustion chamber to form an exhaust gas, means for permitting the gas to exit from the bottom of the combustion chamber, means for diluting the exhaust with air to form a flue gas, and means for directing the flue gas from the bottom of the combustion chamber out of the outlet of the device.

  • Patent number: 4966611
    Abstract: An apparatus and process for adsorbing volatile organic compounds, or VOCs, and efficiently regenerating adsorbent material in an emission control system. Flue gas, emitted from a combustion unit burning an outside fuel and desorbed VOCs, is humidified and cooled with a set of water injectors. The resultant humidified flue gas is directed through the adsorbent material, which is rapidly superheated without pressurization. A method for controlling the regeneration cycle of the emission control system includes at least three sensor configurations including a breakthrough sensor, a desorbed gas sensor and a flue gas temperature sensor.
