Abstract: A pair of hair trimming shears has two pivotally connected blades with integral handles. Each blade carries a plurality of teeth which project upwardly from the surface of the blade; when the blades are closed upon one another, the tooth peaks on one blade engage the roots of the teeth on the other blade in meshing engagement. The teeth are of irregular triangular cross-sectional configuration, which produces a non-uniform, zig-zag cut line that disappears when combed. Thus, the shears permit shortening of hair length without creating undesirably defined cut lines.

Abstract: A centrifugal pump is quickly and easily fitted with a cartridge-type replacement seal where its impeller shaft emerges from its casing, even though the casing is badly corroded in the region at which the seal is to fit against it. To this end, the impeller shaft is removed from the casing and stripped of its bearings, it being replaced by an arbor that carries a grinding wheel. This arbor is installed in the bearings with the grinding wheel presented toward the corroded surface of the casing. The arbor is rotated and at the same time an axially directed force is applied to it to force the grinding wheel against the corroded casing surface. The grinding wheel removes the corrosion, leaving the casing with a flat ground surface surrounding the bore through which the shaft normally extends out of the housing. The same procedure is repeated at the other end of the housing, if necessary.
