Abstract: A cable sealing arrangement is provided for limiting the ingress of fluid into a location about a cable, such as a telephone wire enclosure, which generally includes a fitting, two sealing members, and two nuts. The sealing arrangement provides multiple redundant seals defined by the interfaces of tapered surfaces on the sealing members and the fitting, as well as, the interfaces of tapered surfaces on the sealing members and the nuts. By tightening the nuts onto the fitting, the nuts cause compression of the sealing members resulting in tight engagement of a cable.
Abstract: A highly efficient process for the production and recovery of pure succinic acid from a succinate salt that involves minimal use of additional reagents, and produces virtually no waste by-products, and permits internal recycle of the base and acid values, is provided. The method involves the formation of diammonium succinate, either by using an ammonium ion based material to maintain neutral8 pH in the fermenter or by substituting the ammonium cation for the cation of the succinate salt created in the fermenter. The diammonium succinate can then be reacted with a sulfate ion, such as by combining the diammonium succinate with ammonium bisulfate and/or sulfuric acid at sufficiently low pH to yield succinic acid and ammonium sulfate. The ammonium sulfate is advantageously cracked thermally into ammonia and ammonium bisulfate. The succinic acid can be purified with a methanol dissolution step. Various filtration, reflux and reutilization steps can also be employed.
