Abstract: This invention relates to enzymatic detergent compositions containing a combination of anionic and cationic surface-active agents. In more detail, these compositions contain as essential ingredients enzymes, preferably proteases, in combination with an essentially binary active system comprising a cationic surface-active agent and an anionic surface-active agent whereby these detergent ingredients are to used in well-defined ratios. The performance advantages derivable from the use of these compositions principally reside in the improved cleaning, especially stain removal, performance. Additionally, some textile softening can be obtained from the compositions claimed as well. Obviously, the occurrennce of that latter advantage depends upon the nature of the cationic-active ingredients used and upon the ratio of cationic to anionic surface-active agents.

Abstract: Composite members comprising a substrate of fine grained istropic graphite having a density of at least about 1.75 gr/cc, a coefficient of thermal expansion of from about 7.5 to 8.3 inch per inch per .degree.C.times.10.sup.-.sup.6, in which the grains are of a maximum particle size of less than 0.001 inch, and characterized by a relatively uniform distribution of many interconnected fine pores of an average diameter of about 5 microns and less, the pores extending to the surface of the member, and a selected refractory meatal carbide coating firmly bonded to and conforming to the surface of the isotropic graphite member, the refractory metal carbide coating and the isotropic graphite having closely matching coefficients of thermal expansion. Such coated members are particularly well suited for use as anodes and other electrical members, particularly for use at elevated temperatures. Rotating anodes for X-ray tubes comprising such members are an application.

Abstract: Coating apparatus for applying a coating liquid to a moving roll. The apparatus has a trough-like pan, longer than the width of the roll surface to be coated, for holding a supply of the coating liquid. A pair of weirs is mounted on the pan which holds the coating liquid partially impounded therebetween. The weirs are spaced closer than the ends of the roll and the width of the roll surface to be coated. The weirs each are formed with a curved concave central portion having a radius the same or slightly larger than the radius of the roll, and with at least one overflow end portion to serve as a spillway. Coating liquid is supplied continuously to the central portion of the pan between the weirs and is drained continuously from the weir overflow end portions. The level of the coating liquid between the weirs is maintained at a higher level than coating liquid outside the weirs.
