In order to assure the geometric uniformity of a tire molded with a segment mold when the sculpturing of said tire includes blocks 11 surrounded by recesses formed by grooves 15 and incisions 16, the said grooves 15 are thinned at the level of the joint planes 550 between segments. Furthermore, wear indicators 17 are arranged at the level of the joint planes 550 between segments.

In a tire mold (22) having a pair of mold parts separable about cooperating surfaces (62,64) of the respective mold parts which define a parting line region, each of the mold parts includes a surface defining at least a portion of a cavity for shaping a tire. The tire mold further includes a plurality of pockets (108,122) for defining a respective plurality of circumferentially arranged tread elem...

A method of treating a rubber expandable tire cure bladder by forming a base release coat thereon followed by application of a lubricant topcoat. The base release coat is derived by applying a composite of an hydroxyl terminated polyorganosiloxane and an aminoorganosilane to an expanded bladder and thereafter applying a lubricant topcoat derived from selected polyorganosiloxane components. The inv...

A method for braking and/or stopping a vehicle travelling along a track, e.g. a railway track, by means of an apparatus that includes stationary equipment (1) attached to the track and provided with a magnetic field generating unit (A), as well as mobile equipment (3) including at least one antenna (5) preferably mounted on the underside of the vehicle for interaction with the generating unit (A)....

In the present invention, a force to separate the mold portions for both sides of tire, created by the pressure of a heating/pressurizing medium introduced into a tire during the vulcanization of tire, is offset via an upper disk (114), a segment (110) having protrusions at both ends, and a lower disk (103). A force in the radial direction to move a tread mold (109) outward is offset via the segme...

The present invention is a process of making strap using both post consumer and non-post consumer PET of wide distribution intrinsic viscosity (IV) through direct solid state polymerization in a non-peletized state to produce PET with an increased, heterogenous IV suitable for high performance strap extrusion. The process increases the IV of post-consumer resins, consisting principally of polyethy...

A phase shift mask, having a vernier or box-in-box pattern in an area corresponding to the scribe line of a wafer, allowing the degree of overlap between the light screen pattern and the phase shift film pattern to be accurately examined during wafer processing, whereby the product yield and the reliability can be much improved.

The present invention relates to a phase shift mask for modifying blackout patterns at the peripheral sites of the mask, thereby capable of compensating the differences in the light intensity at the peripheral sites of the mask where the light intensity is relatively reduced after light has passed through the mask. The present invention enables the uniformity of critical dimension of the patterns ...
