摘要： Methods for reducing cavitation in impulse or drop on demand ink jetting devices are provided. Impulse ink jet compositions including antioxidant are also provided which are suitable for printing clear, well-defined alphanumeric text or low spread, narrow bar width bar codes on porous substrates such as Kraft paper or corrugated cardboard. The antioxidant additive lowers the dissolved oxygen level in the ink, thereby enhancing the jetting performance of the printhead.

摘要： Methods for reducing cavitation in impulse or drop on demand ink jetting devices are provided. Impulse ink jet compositions comprising antioxidant are also provided which are suitable for printing clear, well-defined alphanumeric text or low spread, narrow bar width bar codes on porous substrates such as Kraft paper or corrugated cardboard. The ink compositions preferably comprise from about 20 to 50 percent by weight of a carbon black dispersion, from about 10 to 20 percent by weight of a dispersion medium, from about 40 to 60 percent by weight of a plasticizer and less than 2% of an antioxidant additive. The antioxidant additive lowers the dissolve oxygen level in the ink, thereby enhancing the jetting perfomance of the printhead.

摘要： Disclosed are hydrophilic polyolefinic microporous materials and a method for the preparation thereof. Such materials are prepared by impregnating a normally hydrophobic polyolefinic microporous substrate material with a solution of a nonionic alkylphenoxy poly(ethyleneoxy) ethanol surfactant having an HLB of from about 10 to 15 in a solvent system comprising from about 55 to about 65 volume percent methanol or acetone and from about 35 to about 45 volume percent water. It has been discovered that polyolefinic microporous materials rendered hydrophilic by this technique not only wet rapidly, but in addition may be multiply re-wet with aqueous solutions, such as aqueous alkali solutions, with excellent retention of their hydrophilic properties. The hydrophilic polyolefinic microporous materials of this invention find particular application as battery separators and as membranes for use in various chemical, medical and biotechnical processes.

摘要： The present invention provides an improved process whereby the thermal stabilization of acrylic fibers is accelerated. The process comprises providing a zone of electron radiation and continuously passing a continuous length of acrylic fibrous material through the zone so as to provide an energy absorption of from about 5 to about 30 megarads. The residence time of the acrylic fibrous material in the zone of electron radiation is less than five seconds. The continuous length of acrylic fibrous material is subsequently continuously passed through a thermal stabilization zone wherein the acrylic fibrous material is heated in an oxygen-containing atmosphere provided at a temperature in the range of about 220.degree. C. to 310.degree. C. for about 10 to 30 minutes. The acrylic fibrous material formed thereby is thermally stabilized (i.e., black in appearance, retains its original fibrous configuration substantially intact, and is non-burning when subjected to an ordinary match flame). The electron radiation treatment has surprisingly been found to accelerate the desired thermal stabilization when compared to prior art processes which do not include the treatment of acrylic fibrous material by electron radiation.
摘要翻译：本发明提供了改进丙烯酸纤维的热稳定化加工方法。该方法包括提供电子辐射区域并连续地使连续长度的丙烯酸纤维材料通过该区域，以提供约5至约30兆拉德的能量吸收。丙烯酸纤维材料在电子辐射区域的停留时间少于5秒。丙烯酸纤维材料的连续长度随后连续通过热稳定区，其中将丙烯酸纤维材料在约220℃至310℃的温度范围内提供的含氧气氛中加热约10分钟至30分钟。由此形成的丙烯酸类纤维材料是热稳定的（即，外观为黑色，保持其原始的纤维状态基本上完整，并且在经受普通火焰时不燃）。与不包括通过电子辐射处理丙烯酸纤维材料的现有技术方法相比，发现电子辐射处理令人惊奇地加速了所需的热稳定性。
