Abstract: An apparatus and process is provided for continuously depositing solid carbon at atmospheric pressure onto the surfaces and in the porosity of a thin substrate material.

Abstract: A filter media structure, which is capable of operating in the micro- and nanofiltration regime, offers: low cost, durability, high temperature and chemical resistance, high permeability, high flow rate, low pressure drop across the filter media, high mechanical strength, separation efficiency, and biocompatibility. The filter media structure is comprised of mixture of carbon or ceramic fibers and inorganic fiber whiskers generally having a diameter of from about 0.03 to about 5 microns. The present invention further provides a method of preparing a filter media structure comprising mixing together a) inorganic fibers; b) inorganic fiber whiskers; c) a water soluble binder, and optionally depositing a thin layer of pyrolytic carbon on the surface of the inorganic fibers and inorganic fiber whiskers comprising the filter media structure. The filter media structure is selected from the group consisting of a paper, felt and fabric.

Abstract: The frictional properties test mechanism (10) comprises a shaft dynamometer (12) connected with a wheel element (14) that is coupled with a braking mechanism (16) for the wheel element (14). The braking mechanism comprises a single rotor (25)/double stator (27) disc brake whose torque tube (29) is attached to a piston housing (40) and torque load cell (54). The piston housing (40), torque armature end plate (41), and torque load cell (54) are mounted by way of bearings (95) within a stationary framework (100), and connected with an oscillatory motion mechanism (18). Located adjacent the stationary framework (100) and connected by arms (24) to the end plate (41) and torque load cell (54) is a pair of spring mechanisms (20) and a pair of hydraulic cylinders (22), which are part of the oscillatory motion mechanism (18). A control and display console (121) operates the dynamometer (12) in order to effect rotary motion of the wheel element (14) and operation of the braking mechanism (16).
