A pipe support is provided that includes a frame capable of being placed around an existing pipe and a plurality of support members within the frame. The frame is a hollow cylinder that includes two connectable halves divided along the diameter of the hollow cylinder. The pipe support includes two bearing rings connected to the frame for supporting each of the plurality of members at a minimum of two contact points. Each of the two bearing rings include bearing points for each support member arranged in a cylindrical pattern concentric with the hollow cylinder frame. The pipe support includes means for rotating each of the support members at a first contact point with respect to a second contact point so that the support members engage a pipe placed within the pipe support. The support members are rods that provide vibration isolation to a pipe placed within the pipe support.

Universal support and vibration isolator

A structure that positions rotating shafts and allows continuing transmission of rotary motion between shafts or shaft segments that are not aligned with one another or that may from time to time become misaligned. The invention reduces the undesirable effect of torque or torsional transients on rotary positioning and continued transmission of rotary motion, as well as reducing vibration resulting from linear or other angular displacement on either side of the joint. The structure comprises opposing outer and inner plates, each engaging a corresponding shaft or shaft segment. The plates define a plurality of holes that support flexible members. The flexible members extend through the plates on adjacent shafts or shaft segments around the shaft ends. Torque may be transmitted from one shaft to another by the flexible members.

Variable stiffness flexible joint

A vibration isolator with an adjustable response. A vibration isolator for isolating a vibration source from a support structure include a base in engagement with the support structure and two supports connected to the base. At least one of the supports is slidably connected to the base. A flexible member having a generally elongate shape and an elongate length is supported by the two supports. The flexible member is attachable to the vibration source. Each support slidably engages the flexible member such that the flexible member can move relative to each support with the support that is slidably connected to the base being moveable along the elongate length of the flexible member.

Vibration isolator with adjustable response

A shock absorbing device having an axial friction brake for the minimization of dynamic motion while allowing motion, seen as especially useful as an alternative to, or in the replacement of, snubber devices. The shock absorbing device has a movable shaft which is attached to the object to be supported during dynamic motion at one end and a frictional surface which contacts a brake assembly at the other. The brake assembly is located within a housing, which is directly or indirectly attached to a nonmovable support, and is provided with one or more friction pads which contact the frictional surface. The brake assembly may be adjustable for varying load amplitude.

Impact energy absorbing pipe restraints are provided which include a laminated strap for surrounding at least a portion of the circumference of a high energy pipe to restrain the movement of the high energy pipe in at least one direction during rupture. The laminated strap is formed of a ductile material, i.e., one having the property of substantial elongation in the plastic state, to absorb the impact energy of the ruptured pipe. Advantageously, an elastic anchor means is affixed to the ends of the laminated strap to anchor the laminated strap about the high energy pipe and enable pivotal movement of the laminated strap relative to the high energy pipe to minimize any bending moment at the ends of the laminated strap, thereby minimizing any detraction in the allowable strain of the laminated strap. Another form of impact energy absorbing restraint device includes a pipe positioned adjacent the high energy pipe and arranged substantially transverse to the longitudinal axis thereof to restrain the movement of the high energy pipe in at least one direction by absorbing the impact energy of the high energy pipe during rupture by crushing of the restraining pipe therewith. Advantageously, crushing of the restraining pipe causes the ends of the restraining pipe to move upward so that in effect a well is formed by the restraining pipe which aids in the absorption of energy and restricts lateral movement of the ruptured high energy pipe.
