| 94 | Pre-pressurized polyurethane skate wheel | US975809 | 1997-07-10 | US06085815A | 2000-07-11 | Neal Piper; Tom Peterson |
| The present invention is a pre-pressurized in-line skate wheel which is capable of being pressurized at low levels and which further includes an integral bladder device having an annular tube and three bladder rods which are in fluid communication with respect to each other. The wheel is configured with a rigid polyurethane hub formed with a drop center and further having a pair of radially extending flanges with three pairs of axial openings. The hub is further formed with three radially projecting spokes. The tire body surrounds the bladder device and is constructed of a generally more resilient polyurethane which bonds to the hub, flanges and bladder. The method of manufacture utilizes blow molding techniques for the bladder device which includes a post vulcanization chlorine bath. The tire body is formed using liquid thermoset polyurethane poured into an open cast mold. The resulting wheel ensures the rider of a long lasting, light weight tire with exceptional shock absorption properties to therefore provide a smooth and comfortable ride. | ||||||

| 97 | Honeycomb non-pneumatic tire with a single web on one side | US364344 | 1989-06-09 | US4945962A | 1990-08-07 | Scott R. Pajtas |
| A side web non-pneumatic tire ("SWNPT") is integrally molded from a stiff, resilient elastomeric material with particular specifications, to form a unitary honeycomb structure bounded by integrally molded outer and inner cylindrical coaxial and coextensive members ("hoops"), and, a single side web member. The outer hoop is supported and cushioned by the honeycomb which comprises a plurality of circumferentially spaced apart, angularly oppositely directed planar rib members (ribs) bounded by the side web on one side only. The side web, preferably on the outboard edge of the hoops, connects the hoops near their outboard edges. The opposite side surfaces of the side web lie at an angle .theta. in the range from 0.degree. to 30.degree. on either side of vertical to the rotational axis of the SWNPT. The ribs extend axially along the inner and outer hoops, connecting them, and the outboard edges of all the ribs lie upon the inboard face of the web. The ribs on each side are angled at opposite angles in the range from 15.degree. to 75.degree. to radial planes which intersect them at their radially inner ends. A rubber tread is secured to the outer surface of the structural elements of the SWNPT provide a load-supporting outer hoop. The coaction of the structure which, in operation, is subjected to continuous compression and tensile forces as it travels over the ground. Deformation and buckling characteristics of the SWNPT are derived from the honeycomb structure of an elastomer which provides the SWNPT with "ride" and "handling" comparable to those of a conventional pneumatic tire. The outer hoop has a vulcanized rubber tread secured to the hoop's outer surface to withstand travel over a road surface. The unribbed face of the single side web may be faced with an elastomeric sidewall to resemble the sidewall of a conventional pneumatic tire. | ||||||

| 100 | CONTROLLING THE FORMATION OF IMPERFECTIONS DUE TO POLYMERIC SHRINKAGE DURING MOLDING OPERATIONS | US15540482 | 2014-12-31 | US20170341277A1 | 2017-11-30 | Brian WILSON; Jim ENDICOTT; Chad LANE; Clay BOHN |
| Particular embodiments of the invention include apparatus and methods for compensating for shrinkage of a polymeric material in a mold during curing operations. Embodiments of the method include providing a mold comprising a molding cavity defining an interior mold volume separated from an exterior environment and introducing a volume of polymeric material into the molding cavity. Such methods further include impeding the development of a void in the volume of polymeric material by, either: isolating the volume of polymeric material within the molding cavity from the exterior environment, or reducing the interior mold volume of the molding cavity to at least substantially consume a volume of polymeric material shrinkage. Such methods further include curing the polymeric material to form a molded polymeric form. | ||||||
