    • Steel and plastic drums are utilized in many industries for transporting and storing various liquids which may be utilized as fuels, lubricants, ingredients, process fluids, or the like. Often the liquids transported and stored in such drums are highly caustic and/or hazardous and absolute containment during storage, transport, and handling are essential. For example in the semiconductor industry, caustic chemicals such as hydrofluoric acid are commonplace. Some liquids develop significant internal gas pressures when contained during storage. Such pressures must be periodically vented. Even when drums with such hazardous and caustic liquids are on site and ready for use, great care must be taken in accessing the liquids so as not to expose personnel or the environment to such chemicals.
    • 钢和塑料桶在许多行业中用于运输和存储可用作燃料,润滑剂,成分,工艺流体等的各种液体。 通常,运输和储存在这种桶中的液体是高度腐蚀性和/或危险的,并且在储存,运输和处理过程中绝对安全储存是必不可少的。 例如在半导体工业中,诸如氢氟酸的苛性化学品是常见的。 一些液体在储存期间容纳时会产生显着的内部气体压力。 这种压力必须定期排放。 即使具有这种有害和苛性液体的桶在现场并准备使用,在使用液体时必须格外小心,以免将人员或环境暴露于这些化学品。

    • The RF communications system of the present invention wirelessly communicates data without encountering undue interference problems with other devices and complies with rules governing unlicensed, spectrum-sharing devices. In an example embodiment, a transmitter device includes a digital subsystem powered by a power supply that processes data from another device and a radio frequency (RF) sub-system that transmits the processed data using a frequency hopping scheme. The RF sub-system includes a microprocessor arrangement that ON-OFF keys a voltage controlled oscillator (VCO) and provides a frequency-hopping scheme. The VCO is coupled to a signal frequency spreading arrangement that spreads the signal to a predetermined transmission bandwidth, wherein the frequency spreading occurs during an ON state of the ON-OFF keying and the transmission bandwidth exceeds a reception bandwidth at which the signal will be decoded.

    • A sealing system, sealing system components, and methods of manufacture and use for a vessel that holds corrosive liquid, with the sealing system having a port on the vessel, an insert, and a sealing element. The sealing element is corrosion-resistant, essentially impermeable to corrosive and critical fluids, essentially free of leachable impurities and is made with a material having a Shore A hardness between about 70 and about 95. A preferred material for the sealing ring is the class of materials known as polyolefins. The insert is operably engageable with the port and the sealing element to create a seal between the sealing element and the first and second sealing surfaces to prevent fluid flow through the port.
