Patent number: 5987709Abstract: A re-attachable safety connector may be a single unit or may have a number of components working together as one unit. In the embodiments that have multiple components, connection of the components together may be accomplished by use of a series of pins inserted into a plurality of through bores in the body of the components at the mid-portions, as illustrated herein. Depending on the materials used to manufacture each of the elements of a given embodiment, the pin series may be sheared in half in order to provide for a safety release, or the properties of molded plastic as flexible may be relied upon in order to accomplish a safety release. Second through fourth embodiments are capsule shaped and provide for re-attachment of the chain.Type: GrantFiled: September 30, 1997Date of Patent: November 23, 1999Inventor: Tser-Wen Chou

Patent number: 5988927Abstract: A breakaway system (10) for detachably connecting a tension transmitting belt (12) to a pin (20) includes a connector (24) having a pair of jaws (34a, 34b) that clamp against the sides of the pin to preload the connector to the pin thereby preventing relative motion between the jaws and the pin. When the tension load acting between the belt and pin exceeds a threshold level, the jaws of the connector spread sufficiently to allow the pin (20) to pass through an exit gap (42) at the ends of the jaws, which gap is of a nominal width that is smaller than the width of the pin.Type: GrantFiled: February 27, 1997Date of Patent: November 23, 1999Assignee: Designs Systems, Inc.Inventor: Craig E.

Patent number: 5964124Abstract: An overload protector is provided which is secured to a robot arm and a tool to protect the tool form being overloaded or forced into an abnormal position. A rocker assembly is located within the cavity in the protector and the cavity is pressurized in order to force a wall of the rocker assembly into a sealing relationship with a wall of the cavity. The rocker assembly has a peripheral wall in which a number of semi-conical detents are formed in the wall of the cavity. The detents are accommodated in the recesses when the rocker assembly is in a sealing relationship with the cavity wall. When the tool is overloaded or forced into an abnormal position the rocker assembly rocks in the cavity with resulting leakage of fluid from the cavity and a drop of pressure. A pressure switch detects that drop and signals the robot to stop.Type: GrantFiled: July 9, 1997Date of Patent: October 12, 1999Inventors: Fernando Manuel Rodrigues Nunes, Kaz M. Szmyr

Patent number: 5711629Abstract: The present invention is directed to a rod connector assembly for removably securing a control rod to a spider structure. The rod connector assembly includes a tubular boss fixedly secured to the spider structure and a mounting assembly which includes a receiving structure and a biasing structure. The assembly also includes a cap having a cavity formed therein, the biasing structure including a driver and disposed in the cavity such that the driver extends outwardly from the cavity and into the boss, and wherein the cap is secured to the boss. When the control rod is in a prescribed position with respect to the boss, the mounting assembly is operative to resist rotation of the control rod upon application to the control rod of an amount of torque less than a predetermined amount of torque.Type: GrantFiled: January 11, 1996Date of Patent: January 27, 1998Assignee: Framatome Cogema FuelsInventor: Douglas J.

Patent number: 5391016Abstract: The invention features a new and improved safety treatment for rails, such as a highway guardrail or barrier, which through compression of elongated segments of a telescoping terminal dissipates energy from vehicle impacts approaching from substantially upstream of the rail and reduce the hazard of "spearing." The impact energy is resisted by frictional and, in preferred embodiments, mechanical compression by a smaller segment of a filler disposed within a larger segment. In some embodiments, the invention further provides a nose piece to further reduce the spearing effect.Type: GrantFiled: August 11, 1992Date of Patent: February 21, 1995Assignee: The Texas A&M University SystemInventors: Don L. Ivey, Carl E. Buth, King K. Mak, Dean Sicking

Patent number: 5315064Abstract: An improved suspended line cable breakaway device includes a first body portion for connecting to a first end of a support cable and a second body portion for connecting to a second end of the support cable. The first body portion includes resilient fingers having nubs, which are releasably received by slots contained in a cavity wall of the second body portion. A biased spreader, slidably contained in a cavity in the second body portion, is displacable axially along the cavity by an external force along the support cable to urge the nubs outwardly such that the second body portion is disengaged from the first body portion, simultaneously disconnecting component lines of a first end of a suspended line from corresponding component lines of a second end of the suspended line. A shield protects the component line connections, which are spaced internal to the device, from the elements.Type: GrantFiled: November 8, 1991Date of Patent: May 24, 1994Assignee: William D.
