US Classification:

524392

Abstract:

Compositions comprising a poly(aryl ether ketone) having intimately dispersed therein, from about 0. 1 to 5% sulfur, by weight, based on the weight of poly(aryl ether ketone), the sulfur present as at least one member of the class consisting of elemental sulfur, aliphatic and aromatic dithiols, polysulfides of the formula --R--S--S-- where R is a bivalent aliphatic or aromatic radical, and inorganic sulphides are useful because of their high tensile modulus, high-temperature adhesive properties, and dimensional stability. In a further embodiment the composition further contains a reinforcing filler such as glass or carbon fibers. In further embodiments the composition may be made into fibers or used as adhesives.

Abstract:

Plate-and-frame membrane modules, assemblies and processes for separating components of a fluid mixture. The assemblies comprise of a pressure vessel filled with, and able to hold, pressurized fluid being processed. Lightweight membrane plate-and-frame modules are contained inside the vessel. Fluid directing conduits direct the fluid streams being processed into and out of the vessel and across the surface of the separating membrane. Because the modules are surrounded by high pressure fluid, the forces acting on the module are small. This means the modules can be made of lightweight, inexpensive materials, such as plastic. The design of the assemblies is such that it allows for modules to be easily replaced as needed. The assemblies are also designed for pressurized feed fluid separations and separation using a sweep fluid on the permeate side of the membrane. The pressure vessel can contain one or several membrane modules.
