  • Patent number: 5739222
    Abstract: A vinyl chloride polymer is prepared through suspension polymerization of a vinyl chloride monomer in the presence of a polymerization initiator in a reactor. The reactor is charged with up to 4/5 of the overall monomer charge to initiate polymerization. Polymerization is carried out under a certain saturated vapor pressure of P1 kgf/cm.sup.2 at a preset polymerization temperature. When the internal pressure of the reactor declines to P2 kgf/cm.sup.2, the remainder of the overall monomer charge is continuously fed to the reactor so as to maintain the internal pressure within the range of (P1-.DELTA.P) wherein .DELTA.P=P1-P2 ranges from 0.1 to 2.0 kgf/cm.sup.2. A vinyl chloride polymer having a high degree of polymerization is efficiently produced while alleviating the load of heat removal.

The finely ground mixture is heat-treated in a temperature range from 650.degree. C. to 900.degree. C. for partial or complete recrystallization. The resulting ultra-fine-grain Sm.sub.2 Fe.sub.17-x M.sub.x C.sub.y magnetic powder is compacted to produce magnet bodies by a hot pressing processing in a temperature range from 650.degree. C. to 900.degree. C. The process is applicable, for example, for the production of hard-magnetic parts based on interstitial Sm.sub.2 Fe.sub.17 C.sub.y compounds.

  • Patent number: 5728336
    Abstract: High-strength, high-modulus, polymeric implants are produced from highly oriented monofilaments and/or films by solvent welding technique. This avoids loss of orientation, as well as thermal and oxidative degradation, which is the common case with the state of art techniques, namely melt extrusion, injection molding and heat compression molding. The invention leads to uniform bonding of the separate structural units (monofilaments or films) into compound-filament or compound-laminate which protects the implant against delamination. Monofilaments of films are swollen at the surface with a suitable solvent which does not destroy the orientation in the core. A bundle, resp. a sandwich of the swollen monofilaments or films is pulled through an orifice generating compressive stresses between the filaments, resp. films. Solvent removal from the swollen compressed interfaces leads to a homogenous welding of the monofilaments or films.

  • Patent number: 5725260
    Abstract: A locking arrangement comprises a movable control member at the wing and a stationary counter-member at the frame. The control member is arranged at a connecting rod and is displaceable longitudinally along with the latter by means of a handle. In this way, the locking arrangement is displaced between a closing position and a releasing position. In order to achieve a trouble-free arrangement with a reliable closing position, at least one lever with a hook opening is provided in the counter-member which cooperates with the control member as a hook lever. This hook lever is swivelable transversely to the displacement direction of the control member. In the closing position, the hook lever is swiveled toward the control member until a hook opening receives the control member and its outer hook leg engages in front of the control member. In the releasing position, the hook lever is swiveled away from the control member and its outer hook leg is situated outside of the displacement direction of the control member.
