  • Patent number: 4213658
    Abstract: A tool guide bushing mounting assembly comprised of a bushing liner which has a threaded sleeve for a locking screw secured to it with an adhesive. The locking screw sleeve is secured to the liner with a metal carbide epoxy securely positioning the sleeve relative to the bushing liner. The bushing mounting assembly may then be cast into a tool guide sometimes called a jig with the liner flush with the top and bottom surfaces of the jig, assuring proper positioning of the locking screw with respect to the bushing. The universal bushing mounting assembly may be used with either slip renewable, slip/fixed renewable or fixed renewable bushings.

  • Patent number: 4051186
    Abstract: Biologically active substances having labile aryl groups can be converted to the corresponding aryl amine derivatives. The biologically active substances are reacted with a diazonium compound which optionally can be linked to a solid, inorganic carrier such as porous glass beads for ease of purification. The diazo reaction product is then reductively cleaved with a chemical reducing agent such as with hydrosulfite to yield the desired amine derivative. A preferred class of biologically active substances used herein is the catecholamines.
