Articulated ball connector for use with pipeline

Abstract: An improved articulated ball connector for use with pipelines as disclosed. In the illustrated embodiment, a sphere is attached to the end of a pipeline. A collar is fitted about the sphere. The collar has a surface contoured to match the surface of the sphere and its rotates or deflects through a designated angle. The collar has an encircling outer groove. A cup shaped receptacle receives the curved surface of the ball. The collar is abutted against a transverse shoulder on the cup shaped receptacle. The ball is pivoted relative to the cup shaped receptacle and the collar. A ring having a cross section which is U-shaped latches about the cup shaped receptacle and the collar. The U-shaped cross section includes upper and lower shoulders which protrude inwardly and engage the cup shaped receptacle and the groove in the collar. The ring is squeezed radially inwardly to clamp the cup shaped receptacle and the collar together. The ring is held at the radially inwardly directed position by means of a tapered wedge which fully encircles it and jams it inwardly. The tapered wedge is in the form of a hydraulically moved ring within a cylindrical housing.

Endoscopic suture cinch system

Abstract: A two-part suture cinch includes a collar and a plug. A cinch applicator is also provided, and includes an elongate tubular member, a plunger engaged within the distal end of the tubular member, a flexible shaft extending through the tubular member and plunger, and a proximal handle for moving the shaft longitudinally relative to the tubular member. The plunger includes a distal housing for the collar of the cinch, and the plug is coupled to the distal end of the flexible shaft. The suture is thread through the collar and a portion of the applicator. Operation of the applicator draws the plug into the collar and clamps the suture between the plug and collar. In addition, once the plug is coupled in to the collar, the plunger is displaced proximally to release the two-part cinch form the applicator. A method for applying the cinch is also provided.

Posterior spinal implant

Abstract: A spinal screw or hook has a slotted head to receive a support rod. A two-piece rod retainer is provided with an outer ring-like collar locked into the interior of the slotted head and a fastener extending through the collar to contact a support rod in the bottom of the slot.

Adjustable length tap and method for drilling and tapping a bore in bone

Abstract: The present invention is directed to an adjustable self drilling tap assembly and method for drilling and tapping bores in bone for use in orthopedic procedures to treat bone. The adjustable length tap assembly includes a shaft having cutting threads for drilling holes in bone, a stop collar configured and dimensioned to be translatable along the longitudinal axis of the shaft, and a locking collar comprising a member configured and dimensioned to be received over at least a portion of the stop collar. The locking collar preferably is configured and dimensioned to engage with the stop collar to adjustably set the effective length for the cutting threads and to prevent movement of the stop collar along the longitudinal axis of the shaft.

Delinquency as the failure of personal and social controls.

Abstract: white collar group is over-represented at Indiana University. 3. The farming, semi-skilled and unskilled groups are strongly attracted by the teaching profession. 4. Students from the farming and blue collar groups stand a better chance of having their college education postponed or interrupted by a work experience than students coming from the white collar group. 5. Students from the white collar group stand a better chance of becoming members of social fraternities at Indiana University than students coming from the farming and blue collar groups. 6. The G. I. Bill of Rights has increased the proportion of students from the blue collar group at Indiana University from 90 to 113 per cent.
