A method for processing a curved plastic panel is to first form a hard coating layer, an optical function layer, and a printing layer on a flat plastic substrate, and then cut it into a predetermined shape, and then use a hot pressing and curving device to perform a hot pressing and curving process to the flat plastic substrate in order to make it becoming a curved plastic substrate. The hot pressing and curving device can simultaneously perform hot pressing during the heating process, and has the functions of real-time monitoring of the local temperature and the local curvature forming state, and then feedback to the local heating and curvature forming mechanism for adjustments. The monitoring of temperature and curvature can be divided into multiple stages, which can be monitored stage by stage and adjusted for heating or curvature forming to improve production yield.

A paving tile is made of a first rubber material and a second rubber material that is dissimilar from the first rubber material. The first rubber material may be a recycled rubber material, such as crumb rubber granules from scrap vehicle tires. The second rubber material may be a nitrile rubber material, such as nitrile butadiene rubber (NBR). The crumb rubber material is disposed within a mold and leveled. A relatively thin layer of the NBR material is positioned onto the crumb rubber material and the crumb rubber material and the NBR material are chemically bonded without an adhesive using a compression molding process including at least one of a preselected pressure, a preselected temperature and a preselected period of time. The recycled rubber material may have a first color and the nitrile rubber material may have a second color that is different than the first color.

An acetabular cup prosthesis features conical pegs. The edge of each peg has an outer portion facing away from the edge of the other peg, and the outer portions of the pegs are parallel to or converging toward each other such that, when in use, the prosthesis can be securely inserted into a prepared bone cavity.

This invention related to a method of forming a polymer component and comprises blending polymer particles with antioxidant to form a mixture in which the antioxidant coats the polymer particles, irradiating the polymer particles to cross-link the polymer particles therein and forming the irradiated mixture into a consolidated component. The invention also relates to a method of forming an articular surface for a prosthesis and a prosthesis having a polymer articular bearing surface wherein at least one predetermined portion of the bearing surface is provided with cross-linked polymer bonds.

A method of making a multilayer article includes providing a mold defining a first cavity with a removable element therein; placing a first particulate component in the cavity; compressing the component along a first axis in a first compression step to form a first layer of the article; removing the element from the cavity after formation of the first layer; placing one or more additional particulate components in the mold; compressing the one or more additional particulate components along the first axis in one or more additional compression steps after removal of the element to form one or more additional layers of the article, wherein the first layer meets one of the one or more additional layers along a first interface substantially parallel to the first axis and the first layer meets one of the one or more additional layers along a second interface substantially perpendicular to the first axis.

An article is molded from first and second thermosetting elastomer compositions each comprising free-radically curable elastomer and free radical initiator but different from one another. The first thermosetting elastomer composition is molded to fill a first area of a mold cavity at a first temperature at which the first free radical initiator has a half-lifeabout 10 minutes or at which the first thermosetting elastomer composition has an increase in torque less than 10% of a total increase in torque at full cure. The second thermosetting elastomer composition is then inserted into the mold cavity, and the mold is heated to fully cure the article, for example a temperature at which each free radical initiator has a half-lifeabout 1 minute, with the second composition filling a second area of the mold cavity before or during heating and curing.

A graft compression system for compressing soft tissue grafts used in connection with reconstructive surgery. The graft compression system includes an upper press body and lower press body, pivotally couple to one another, each having inner sides having a plurality of parallel semi-circular shaped channels formed thereon. The plurality of parallel semi-circular shaped channels have sequentially decreasing channel widths. The upper press body and said lower press body of the graft compression system are configured to pivot about a pivot pin such that the inner sides abut one another, and such that the two sets of semi-circular shaped channels are substantially aligned with one another so as to receive a graft for compression. A screw press barrel is attached to the lower press body, on a side opposite the pivot pin, and is configured to compress the upper press body and lower press body.
