摘要:
A process to coat a shear thickening fluid onto a material which comprises emulsifying dispersions of a shear thickening fluid (STF) dissolved in a miscible carrier fluid or a partially miscible carrier fluid to form an emulsion and applying said emulsion to the material. The invention also relates to a suspoemulsion containing a shear thickening fluid which has been emulsified in a volatile solvent. The invention further relates to a method coating a material. The invention further relates to a method of a coating a material with the suspoemulsion.

摘要:
An armor composite material has been invented which contains a fabric which has been impregnated with shear thickening fluid. This invention offers a ballistic resistant material that is more flexible and less bulky than comparable, conventional ballistic fabric. The material in the alternative can be puncture resistant. The invented material offers superior ballistic performance and/or puncture resistance compared to conventional ballistic fabric-based materials of equal thickness. The invented material can be applied to applications requiring armor that is compact and/or flexible, such as body armor, protective clothing and flexible protective devices and shields, and stab resistant clothing and devices.
摘要:
An improved process for the removal of malodorous sulfur compounds, for example H.sub.2 S and methyl mercaptan, from gas streams containing oxygen in which a bed of activated carbon treated with PbOAc, NaOH and moisture is used to remove said compounds. The treatment, which may also be combined with regeneration of the activated carbon, is effected, typically, by applying to the carbon one bed volume of dilute (4-6%) NaOH and PbOAc solution, draining and drying with 50-100% R.H. air.
摘要:
A glove or partial glove comprising a palmar portion and a dorsal portion comprising one or more finger/thumb extensions, the portions joined together at a sealed seam, the seam positioned such that the seam on each of the finger/thumb extensions is positioned adjacent the dorsal aspect of the user's finger/thumb with the palmar aspect extending over the fingertip in a hood-like configuration. The glove portions may comprise a shear-thickening-fluid (STF) treated textile base, including a multi-ply construction in which each ply comprises an STF-treated textile base. The glove may comprise an integral pathogen barrier, such as a coating that is impervious to blood and bloodborne pathogens, and may have one or more features that aids donning and/or provides an adjustable fit. The glove or partial glove may be a first glove in a glove system including at least a second, latex glove to be worn over the first glove.

摘要:
A process for concentrating and destroying the perchlorate and nitrate anions present in ground water and drinking water sources is disclosed. In the process, the perchlorate and nitrate anions present in feed water are concentrated into a much smaller effluent stream. A typical process configuration involves using a continuous contacter apparatus known as ISEP wherein the perchlorate present in feed water is adsorbed on to an ion-exchange resin resulting in a perchlorate-free treated water. The ISEP unit also incorporates a regeneration zone where the adsorbed perchlorate is effectively removed from the resin using relatively low volumes of concentrated brine solution as the regenerant. The waste from the ISEP unit is a concentrated brine solution containing perchlorate and other anions that may be present in the feed stream. This waste stream from the ISEP unit is treated by a combination of: i) bioreactor or a catalytic reactor that removes perchlorate and nitrate (if present) anions ii) sulfate removal (if needed) by nanofiltration or other established methods and iii) filters and a disinfectant system to render the brine stream re-usable. The resulting stream is recycled back into the process. The entire process results in a very small waste stream that needs disposal. The process can be applied to feed water streams containing either perchlorate alone or perchlorate and other anions such as nitrate, sulfate and bicarbonate.
