Patent number: 7971422Abstract: A device for fastening emergency equipment to a vessel includes a hydrostatic release mechanism, a tether, and a float-free link. The tether is attached to the hydrostatic release mechanism and provides an attachment point for lashing the emergency equipment to the vessel. The tether may also be threaded through openings in the curved partially tubular body of the float-free link. A breakable bridge is integrally coupled to the body of the float-free link to form a closed loop. The breakable bridge is designed to be the break point when the emergency equipment needs to be freed from a vessel that has sunk below a predetermined depth. When the vessel sinks below the predetermined depth, the hydrostatic release mechanism severs the tether thus freeing the emergency equipment from one point of attachment to the vessel. The bridge is designed to break when the strain on the fastening line, e.g., the painter line, is between a predetermined minimum force and maximum force.Type: GrantFiled: June 25, 2010Date of Patent: July 5, 2011Assignee: General Pneumatics Corp.Inventors: Taila Shnayder, Mark S.

Patent number: 5399042Abstract: A swivel utilizing multiple angular contact bearings arranged in such a manner as to provide preloading for two-directional axial and radial thrust stability. This bearing arrangement of angular contact ball bearings applied to swivels adds capabilities of compression and side loading. The boring operations for which the present invention is primarily intended commonly take place in a pressurized environment of liquid and dirt slurry, thereby making sealing of the bearing cavity critical to the exclusion of foreign material which would damage the bearings. The rigidity of the assembly provided by the preloaded bearings creates critical stability in the seal area. The swivel provides the capability for bi-directional axial load support, radial load support, and a sealed inner bearing structure for both passive swivel and power driven swivel products. A particular load capacity is obtained through application of counterpoised arrangements of particular sizes of angular contact ball bearings.Type: GrantFiled: June 7, 1993Date of Patent: March 21, 1995Inventor: Leonard L. Ivel

Patent number: 4467598Abstract: An energy absorbing chain which can be used as a "one shot" safety chain to absorb sudden impacts or short term tensional forces is disclosed. According to the invention, the safety chain is made of a metal having high ductility such that the chain will tend to deform, stretch, and/or deflect rather than break. According to a preferred embodiment, the chain may include links such as links (36), (38), (40) and (42) each of which includes a twist of 90.degree. to increase the amount of available deformation. In the preferred embodiment, link (36) and (40) include a twist in a first direction such as a clockwise direction whereas links (38) and (42) which alternate with links (36) and (40) include a 90.degree. twist in the opposite or counterclockwise direction. Thus upon receiving or being subjected to such tensional forces, the links can deform as shown by links (58), (60) and (62) as they absorb energy for a short period of time.Type: GrantFiled: April 28, 1981Date of Patent: August 28, 1984Inventor: William M.
