  • One-piece collet and process for making same
    Patent number: 4249748
    Abstract: A one-piece collet for use in machine tools, which collet comprises a rear portion which is cold worked to provide a bore of smaller diameter than the bore of the central portion of the collet, which reduced bore is threaded. The cold working of the rear portion produces a transitional area between the different sized bores of the rear and central portions which is characterized by a smooth, uniform grain flow, with unbroken flow lines, resulting in increased tensile strength and longer fatigue life of the collet. The front portion of the collet may also be cold worked to provide a similar transitional area between the central portion of the collet and the reduced bore of the front portion of the collet.

  • Photographic support
    Patent number: 4238280
    Abstract: A photographic support is produced by heat consolidating paper made wholly of thermoplastic synthetic fibres. The consolidation is carried out in such a way as to produce a homogeneous surface film having a desired surface finish for receiving a photographic coating, a fully bonded but still fibrous layer adjacent the film, and a lightly bonded fibrous layer adjacent the fully bonded fibrous layer. The homogeneous surface film is produced in such a manner that its surface is substantially free of pits. This may be achieved by consolidating the web by heating it on one surface while cooling it on the other surface.
