A depth stop on the drive spindle is adjustable relative to the stop sleeve.  An actuating sleeve accessible on the exterior of the screw driving device affords the adjust-ment of the stop sleeve and the depth stop.  A connecting element is secured to the actuating sleeve and is in engagement with the depth stop so that the actuating sleeve and depth stop can be rotated as a unit.  The connecting element is selectively engageable with the stop sleeve so that the actuating sleeve and stop sleeve can be rotated as a unit for adjusting the torque-limiting coupling.

Abstract: GnRH ANTAGONISTS IX                 ABSTRACT OF THE DISCLOSURE          Peptides which inhibit the secretion of gonadotropins by the pituitary gland and inhibit the release of steroids by the gonads.  Administration of an effective amount of such GnRH antagonists prevents ovulation of female mammalian eggs and/or the release of steroids by the gonads.  These peptides may be used to treat steroid-dependent tumors, such as prostatic and mammary tumors.  The peptides are cyclic analogs of the decapeptide GnRH wherein there is a covalent bond between the residue in the 4-position and the residue in the 10-position.  Examples of such bonds include the disulfide linkage between Cys residues, an amide linkage between a side chain amino group and a side chain carboxyl group, a dicarba linkage between side-chain alkyl groups, and a carba linkage between a side-chain alkyl group and a side-chain sulfhydryl group.  An amide linkage with the 4-position residue having the carboxyl group side chain is preferred, with Asp and daP being most preferred.

Title: Corrosion and wear resistant steel
Inventor: SRIDHAR NARASHI
IPC: B23K35/30
Filed: 1987-06-30
Granted: 1992-03-10
Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed  is  a  "duplex"  stainless  steel especially suited for use in conditions requiring a high degree of wear and corrosion resistance;   for example structural fasteners,  such as nuts and bolts as used in chemical processing.   The alloy typically contains,  in weight percent, 12 cobalt, 20 chromium, 11 nickel, 5 silicon, 1.5 molybdenum, 2 copper, up to .2 nitrogen and up  to  .01  carbon.    The  "duplex" structure preferably consists of about 30% ferrite and the balance essentially austenite.
