A bearing unit for holding a shaft, the bearing unit having a housing and integral lands extending inwardly from the inner surface of the housing for tangentially engaging the rotating shaft, the bearing unit being made from a slippery polymer alloy comprising a heterogeneous composition of a thermoplastic in a continuous phase, a thermoplastic rubber compound dispersed in the thermoplastic and a lubricant dispersed in the thermoplastic.

Integral bearing unit made from a slippery/polymer alloy

A bearing stave for use in a water-lubricated bearing having a discontinuous surface with a plurality of discrete, separated contact locations for contacting the shaft, the discontinuous surface being made of slippery polymer alloy.

Stave bearing assembly and stave for a bearing assembly

A bearing stave for use in a water lubricated bearing having a discontinuous surface with a plurality of discrete, separated contact locations for contacting the shaft, the discontinuous surface being made of slippery polymer alloy.

A fender protective structure having an inner layer of resilient plastic/elastomer alloy having a delayed elastic response, having voids to reduce weight and allow the inner layer to expand upon impact. A relatively hard top layer is also provided.

Fender protective structure

A bearing assembly for supporting a water-lubricated drive shaft includes a plurality of load-bearing staves made from a composite material known as Slippery Polymer Alloy (SPA and a plurality of rubber staves. The composite staves are spaced circumferentially around the bearing housing on the inner wall. The rubber staves are also spaced circumferentially around the bearing housing, the rubber staves being located between adjoining composite staves and having compression force on their end portions to lock the composite staves in place.

SPA super demountable bearing

A bearing assembly for supporting a drive shaft of a ship wherein the shaft if generally to be supported by such bearing assembly in a horizontally extending position. The bearing assembly has a housing with a cylindrical shell mounted therein having a central bore with a longitudinally extending central axis. The shell has a plurality of circumferentially spaced staves provided therein which project into the central bore to support the drive shaft. The staves have transverse grooves provided therein.

Grooved staved bearing assembly

A bearing assembly for supporting a drive shaft includes a cylindrical housing, and a plurality of elastomeric bearing sections disposed within the housing. The bearing sections are bonded to the housing by first applying a pattern of alternating parallel lines of adhesive to the inner diameter of the housing, installing the bearing sections, and inflating an airbag within the housing to thereby apply a uniform radial pressure to the inside of the housing while the adhesive cures.

A fender protective structure includes a top layer of ultra high molecular weight polyethylene on a resilient layer comprised of a rubber and plastic alloy. Bore holes are provided in the resilient layer for permitting bulging to facilitate energy absorption when the fender protective structure is impacted by a moving object.

A bearing assembly for supporting a drive shaft of a ship wherein the shaft is generally to be supported by such bearing assembly in a horizontally extending position. The bearing assembly has a housing with a cylindrical shell mounted therein having a central bore with a longitudinally extending central axis. The shell has a set of circumferentially spaced staves to support the drive shaft. All of the staves are comprised of a slippery polymer alloy and project into the central bore of the shell. The staves are held in place by gripping members comprised of an elastomeric member compressed by a rigid plate.

Bearing assembly

A bearing assembly for supporting a drive shaft as of a ship wherein the shaft is generally to be supported by such bearing assembly in a horizontally extending position. The bearing assembly has a housing with a cylindrical shell mounted therein having a central bore with a longitudinally extending central axis. The shell may either have a first set of circumferentially spaced staves that are not evenly spaced circumferentially to support the drive shaft, or have a first set and a second set of staves that are circumferentially spaced such that the first set contact the drive shaft while the second set do not contact the drive shaft under normal conditions of load. All of the staves have resilient elastomeric strips that project into the central bore of the shell.

Impact resistant and flame retardant polymer composition, slab-like rectangular solid made of said composition, and composite laminate article having at least one layer of said composition. The polymer composition comprises a maximum of 86 volume percent of ultra high molecular weight polyethylene (UHMWPE), a minimum of 4.40 volume percent of a flame retardant additive or mixture thereof, and a minimum of 6 volume percent of chopped reinforcing fibers, all volumes referring to the densified (molded) state. In addition the bulk volume of the chopped reinforcing fibers, as measured by a tapped density test, must be a minimum of 27 percent of the final molded volume of the composition. The maximum volume % loading of the additives is limited by the requirement that the notched Izod impact strength is a minimum of 7 ft.-lb per inch width. The preferred flame retardant additive is essentially a water insoluble form of ammonium polyphosphate having a water solubility not exceeding 1 gram per 100 grams of water, and the preferred reinforcing fibers are chopped glass fibers about 1/8 to 1/4' inch in length.

Compression molded flame retardant and high impact strength ultra high

A suspension system for a vehicle having a torsion spring interconnecting the wheels and axle to spaced portions of the frame via suspension arms wherein each suspension arm has one end secured to one element of the torsion spring and its other end connected to one end portion of a torsion type shackle. The other end of the shackle has its outer shell connected to the vehicle frame via replaceable shims that adjust the height of the vehicle frame relative to the axle and the ground.
