  • Method and apparatus for stressing a tendon and banding a structure
    Patent number: 4005828
    Abstract: A method and apparatus are disclosed for banding a vertical wall of a large vessel with a highly tensioned tendon payed out from a traveling carriage being driven about the vertical wall. The carriage is suspended from the structure and a circumferential restraining means constrains a primary set of traction wheels driven by a primary hydraulic system and a second set of wheels driven by regenerative hydraulic system into frictional engagement with the vessel wall. The preferred wheels comprise hydraulic motors having an outer rotatable portion or race to which is directly attached an encircling tire. A tendon tensioning mechanism is disclosed with restraining elements having outer frictional surfaces engaging the tendon without slipping and having other frictional surfaces for slipping relative to a force applying means when accommodating elongation of the tendon during tensioning.

  • Flaw detecting apparatus for railroad rails and the like
    Patent number: 4004455
    Abstract: Apparatus is disclosed for use in detecting flaws in the bolt hole area of railroad rails and the like, and is adapted to detect and record the location of an oversized hole indicating a crack or the like. The apparatus utilizes an ultrasonic transducer detector which is actuated by a free running pulse generator, and includes a counter and associated circuitry which compares the time required for the pulse to travel through the rail with a preset time and, if the rail has no flaw, causes an output to be produced that is used to reset the counter. The counter is also triggered by a speed related pulse generator that effectively measures the distance traveled by the car along the rail and thereby measures the size of the flaw. A flaw exceeding a predetermined size which is approximately the diameter of bolt holes, will trigger an alarm and cause a recorder to be activated.

  • Boat hull
    Patent number: 4004534
    Abstract: A boat hull comprising a generally elongated body portion and port and starboard elongated sponsons disposed along the opposite side margins of the body portion and defining elongated running surfaces, the sponsons terminating at respective locations forward of the transom means but aft of the transverse midplane of the hull. A central sponson depends from the body portion centrally of the port and starboard sponsons and defines a further elongated running surface that extends from a location forwardly of the aft terminal ends of the port and starboard sponsons to the approximate location of the transom means. The sponsons, in combination with the body of the hull, define tunnels on opposite sides of the central sponson. These tunnels are open at their respective forward and aft ends for the flow of fluid therealong.

  • Safety closure
    Patent number: 4002259
    Abstract: To prevent leakage of the container contents when a child attempts to turn a child-safe closure in the removal direction, the closure is formed with a series of closely spaced detent members at least one of which will abut a detent member on the container to limit turning of the closure in the removal direction to a degree insufficient to allow leakage. Preferably, a series of six closely adjacent radially extending tab like detent members extend outwardly from the skirt wall of the closure within a quadrant of the skirt wall to assure locking by at least the leading or trailing one of the detent members under the worst tolerance conditions. The intermediate detent members become effective for other tolerance conditions which result in the manufacture of the closure and container which are usually made of molded plastic.

  • Method and apparatus for stressing a tendon and banding a structure
    Patent number: 4002304
    Abstract: A method and apparatus are disclosed for circumferentially banding a circumferential wall of a large vessel with a highly tensioned tendon. The carriage is suspended from the top of the structure and constrained into contact with the wall to travel circumferentially about the vertical structural wall. The carriage is propelled forwardly during banding against the large restraining force, e.g., 30,000 lbs. or more, from the tendon which is connected to the wall by a belt drive means on the carriage which is in driving engagement with upper and lower belts looped about the vessel and extending through the carriage. The belt drive means comprises belt drive drums about which the belts travel after being lifted from the structural wall at the forward end of the carriage. The belts are returned to the structural wall at the rear end of the carriage.
