Segmented polyolefins, which are produced by the reaction of mixtures of powdery polyolefins and polyolefin granulates with unsaturated monomers in the presence of thermally decomposing free radical-forming agents in continuous mixers in two consecutive reaction steps in the solid phase, a reaction step in a solid phase/melt transition phase and a melt homogenizing step, have a high strength and tenacity. The segmented polyolefins, as well as mixtures with conventional polyolefins, are suitable ...

A sprocket has a hub with a wide, carefully-machined, convex, outer surface, has a number of circumferentially-spaced, radially-directed, threaded sockets opening to that outer surface, and has a plurality of arcuate segments. Each of those arcuate segments has a wide, concave, carefully-machined, inner surface which is complementary to a portion of the outer surface of the hub, has a convex outer periphery with a plurality of sprocket teeth thereon, has a plurality of radially-directed, shoulde...

A segmented aperture lens having multiple lens segments having predetermined patterns. Each lens segment may be a fresnel lens. The lens segments may be arranged in a two-dimensional array or a one-dimensional array.

A sectional gasket 11 includes corner junction members 12, straight junction members 13, and extension members 14. The junction members 12 and 13 each include a recess 19, and the recesses 19 each include axially extending laterally inwardly facing sealing surfaces 20 and 21. The extension members 14 each have a uniform lateral cross-sectional configuration along their entire axial extent. Each extension member 14 includes axially extending, parallel, laterally outwardly facing sealing surfaces ...

A mirror comprises a myriad of reflecting surfaces so aligned as to produce a virtual image which may be plain or focused. The surfaces may be irregular in outline to minimize or prevent glint patterns.

A vehicle track comprising continuous belts formed of moulded elastomeric segments joined in end-to-end relationship. The segments are generally flat with enlarged sections at each end to provide transverse ribs. The segments are connected together by connections each of which includes inner and outer plates having concave cross-sections overlying the ribs of adjacent segments, the inner and outer plates being secured together by bolts. The inner and outer plates may be formed by transverse grou...

An improved marker buoy having a body made of nesting segments wherein each segment has a cup-shaped lower portion filled with buoyant material and a hollow cylindrical upper portion with a cup-shaped cavity for nesting with the lower portion of a similar segment. The segments nest one within the other such that the outer wall of each cup-shaped portion reinforces the walls of the segment below it and the nesting segments are held together by a shaft passed longitudinally through the nesting seg...

A method of fabricating a large area, multi-element contactor. A segmented contactor is provided for testing semiconductor devices on a wafer that comprises a plurality of contactor units mounted to a substrate. The contactor units are formed, tested, and assembled to a backing substrate. The contactor units may include leads extending laterally for connection to an external instrument such as a burn-in board. The contactor units include conductive areas such as pads that are placed into contact...

The invention concerns a method of making a segmented mirror, the mirror comprising, in combination (a) a myriad of surfaces carried by a support, certain of said surfaces dimensionally offset from one another in a common direction generally parallel to the general direction of incident radiation to reflected, said surfaces being radiation reflecting sufaces each oriented in such a way that as a group they collectively reflect radiation essentially as they were a continuous reflecting surface, (...

The segmented cigarette includes combustible inside and outside tubular walls that are spaced from each other by ridges extending therebetween. The inside wall holds a plurality of elongated segments of tobacco aligned end to end. Different tobaccos may be utilized in each segment. The upstream, axial end of each segment is sealed by paper. The inside wall includes a plurality of gas passages therethrough near the axial end seal such that gas from the burning end of the cigarette passes through ...
