  • Publication number: 20040069100
    Abstract: The present invention provides a method and article involving a one-piece, unibody spindle liner having a tubular shape with an outside diameter and inside diameter that may be sized to fit virtually any spindle of a turning machine and to readily allow for the feeding therethrough of any size or shape of bar or tube stock. This invention provides that the axial centerline of the workpiece is maintained in concentric axial alignment with the working centerline of the turning machine to reduce wobble or “whip” of the stock during the machining process. The liner's inner bore and diameter is molded to match and allow for feeding of virtually any size and shape stock being turned, including but not limited to round, hex, square, and extruded. The inner bore is molded into the spindle liner along its entire length providing absolute support of the workpiece. The spindle liner also has a flanged mounting end to allow for the proper orientation and attachment to the spindle.

  • Patent number: 6223070
    Abstract: An indwelling catheter having an extremely low profile proximal section. The indwelling catheter of the present invention solves the problems associated with the prior art feeding catheters by providing an extremely low profile proximal section which is situated external to the patient's body when the catheter is in place. The external portion is preferably in the form of a “trap door”, including a flat base portion that lies against the patient's skin and a flat, hinged cover which is operative to seal the proximal opening of the catheter when not in use. In order to retain the catheter and prevent it from being accidentally dislodged, the catheter includes a series of helical coils which are unformed during catheter insertion and then automatically reform in order to hold the catheter in place internally. The catheter is self-adjusting in that fewer or greater loops will automatically reform depending upon the thickness of the patient's abdominal wall.

  • Patent number: 6047581
    Abstract: A vertical rack-type spline-forming machine based on a novel slide base arrangement comprising a pair of vertical slide bases structurally joined by a symmetrically arranged set of tie bars. The structurally-joined vertical slide bases can be rested in an upright position on a non-structural space frame which provides improved access and lift capabilities to the vertical machine. The machine also includes a novel drive system using independent electric motors, one motor associated with each vertical slide base to drive the rack on that base through a roller screw shaft mechanism. The racks are further electronically synchronized through position signals communicated between the motor drives, and the rack home positions are calibrated with electronic "datums" programmed into the motor drives and capable of being re-calibrated in programmable fashion if one of the racks loses synchronicity.

  • Patent number: 4852375
    Abstract: An apparatus (10) and die assembly (26, 30) for forming a splined power transmission member from a thin-walled blank. The apparatus (10) comprises a pair of die assemblies (26, 30), each including a supporting frame (28), first (42) and second (44) die bodies independently mounted on the supporting frame (28) in end-to-end coaxial relationship with each other, with rough (46) and finish (48) spline-forming surfaces formed on the first (42) and second (44) die bodies, respectively. The pair of die assemblies (26, 30) are supported with the spline-forming surfaces of the respective die bodies (42, 44) in spaced, oppoosed, parallel relationship to each other. A power drive mechanism sequentially moves the pair of die assemblies (26, 30) in opposed directions. The power drive means effectuates a rough spline-forming stroke and then returns the die assemblies (26, 30) to the neutral position.

  • Patent number: 4848344
    Abstract: A balloon guide is disclosed which includes a single lumen useful alternately for fluid communication through the distal tip or for inflation of a balloon when the distal end is closed. The guide includes a body formed from coiled wire having a proximal portion in which the coils are held together and a distal portion in which the coils are separable. The balloon is located about the separable coils. A restriction adjacent the distal tip of the guide body is closable by a plug mandril extending through the central lumen of the guide. With the distal tip open, fluid communication is available through the central lumen for pressure measurements, fluid infusion or the like. In an alternate condition, a plug is positioned to close off the distal opening of the guide and also to stretch the coiled wire to separate the coils in the region underlying the balloon, preventing fluid communication through the distal tip, but permitting inflation or deflation of the balloon through the separated wire coils.

  • Patent number: 4829800
    Abstract: An apparatus (12) for cold sizing a round workpiece (14) having round surfaces of cylindrical shapes that are coaxial about a central axis A of the workpiece and have different diameters. A support (54,55) rotatably mounts the workpiece (14) about its central axis A between a pair of die assemblies (24a, 24b) which are spaced from each other. Each die assembly (24a,24b) includes a plurality of dies (56,58,60,62) that are respectively aligned with the round surfaces (46,48,50,52) of the workpiece (14). Movement of the die assemblies in opposite directions as each other engages sizing surfaces (66,68,70,72) of the dies with the aligned round surfaces of the workpiece to pressure size the workpiece surfaces. In one embodiment of the sizing apparatus (12), the die assemblies (24a, 24b) have elongated shapes and are moved rectilinearly in a parallel relationship to each other to perform the sizing.

  • Patent number: 4779476
    Abstract: A power transmission member (42), as well as apparatus (10,110,210) and method for forming the power transmission member (42) from a thin-walled blank. The apparatus (10,110,210) comprises a pair of opposed toothed dies (26,30;112,114;138,140). A toothed mandrel (40) is rotatably supported between the dies and received within the sleeve portion (46), flatly engaging an annular end wall (44) of the member. The dies (26,30;112,114;138,140) and mandrel (40) have chamfered surfaces (68,70), respectively, for forming a chamfered flange (66) on the power transmission member (42) as the toothed surfaces of the dies are relatively moved during the splining operation. A loading notch (122) is formed intermediately along the toothed work surfaces of each die member (112,114;138,140) for receiving a blank to be splined when the notches (122) are vertically aligned with one another in a neutral or loading position on opposite sides of the mandrel.
