  • Patent number: 5167915
    Abstract: A process for producing a rare earth-iron-boron magnet, which includes the steps of: (1) charging a melt spun powder of a rare earth-iron-boron magnet into at least one cavity, which is confined by a pair of electrodes inserted into a hole of an electrically non-conductive ceramic die; (2) subjecting the melt spun powder to a non-equilibrium plasma treatment, under a reduced atmosphere of 10.sup.-1 to 10.sup.-3 Torr, while applying a uniaxial pressure of 200 to 500 kgf/cm.sup.2 to the melt spun powder in the direction connecting the electrodes interposed between a pair of thermally insulating members, thereby fusing the melt spun powder; and (3) heating the fused melt spun powder to a temperature higher than or equal to its crystallization temperature by transferring a Joule's heat generated in the thermally insulating members by passing a current through the members to the melt spun powder thereby causing the plastic deformation of the melt spun powder to form a rare earth-iron-boron magnet.

  • Patent number: 5156792
    Abstract: A catheter is provided which deters the backflow of blood between the insertion needle and the catheter cannula by forming the distal end of the catheter hub so as to restrict the inner diameter of the catheter cannula to a wiping fit with the engaged insertion needle. In a first embodiment the distal end of the catheter hub is pre-formed to its desired final inner dimension. The distal end of the hub is stretched to an oversize condition, the catheter cannula is attached to the hub, and the distal end of the catheter hub is heated, causing a stress relief of the previously stretched hub. The distal end of the catheter hub returns to its pre-formed dimension which will mechanically restrict the diameter of the catheter cannula at that point to form the wiping fit with the engaged needle.

  • Patent number: 5156859
    Abstract: An apparatus for bending a laminated thermoplastic sheet without displacing the lamina relative to one another includes a clamp which functions to hold the sheet during the bending procedure. A support is disposed adjacent the clamp and has a curved surface for forming a bend in the sheet and a flat surface which constitutes an abutment for the part of the sheet being bent. The support is adjustable to vary the angle of bending. A bending device for the sheet comprises a carriage having a bending roller, and a ram whose size approximates that of the flat abutment surface. The sheet is clamped with a portion thereof projecting freely above the flat abutment surface and heated. The bending roller thereupon forces the sheet against the curved surface to bend the sheet and then moves across the projecting portion of the sheet to urge such portion into engagement with the flat abutment surface.

  • Patent number: 5126090
    Abstract: An over-the-needle catheter assembly in which a restriction of the inner diameter of the catheter tube is formed in the proximity of the needle hub. The restriction is formed by heating a portion of the catheter tube to the softening point of the catheter material, stretching the catheter tube to cause the heated portion of the catheter tube to tighten about an inner needle or mandrel, then releasing the stretching force to allow the stretched portion to relax, leaving a small gap between the inner wall of the catheter tube and the outer diameter of the insertion needle. The small gap is preferably sized to be on the order of the size of the diameter of blood cells to restrict the flow of liquids past the restriction and into the catheter hub.

  • Patent number: 5126086
    Abstract: A method for producing a container having an inside bag for the accommodation of a filling material w which is applied by a propellant between the container and the inside bag from a valve or the like, wherein after production of the container, for example by pressing, deep drawing or the like, its interior is provided with an inside protective lacquer and subsequently primed. Thereupon, plastic for the inside bag is injected into the container and the container having the inside bag is subsequently subjected to heat to remove superfluous solvent from the plastic. Then a bottom hole is shaped out for the later introduction of the propellant. After injection of the plastic, the container is placed in an oven and rotated therein for a lengthy period.

  • Patent number: 5116563
    Abstract: An improved process for forming a mechanical fastening prong and the prongs produced thereby. The prongs are produced by deposition of a heated, thermally sensitive material onto a substrate, which is transported at a differential velocity relative to the heated material being deposited to form the prongs. Also, the transported substrate may be drawn away from the point of deposition at an angle. By varying the velocity differential between the substrate and the heated, thermally sensitive material as it is deposited and by varying the angle between the substrate and the point of deposition of the heated thermally sensitive material, the fastening characteristics, particularly the shear strength, of the fastening system formed of these prongs may be advantageously modified.

  • Patent number: 5115552
    Abstract: To seal against liquid leaking out around a rod which is slidably movable lengthwise axially within a chamber containing the liquid through an opening in the rear wall of the chamber, a ring of thermoplastic material is placed in the chamber around the rod and pressed against the rear wall of the chamber while applying heat to cause the thermoplastic material to flow into the opening around the rod and onto the outside of the wall so that when the heat is removed the material sets and latches itself onto the rear wall to seal off the space around the rod while still allowing the rod to slide easily.
