The present invention relates to a heavy duty tire comprising a carcass comprising a carcass ply of cords extending between bead portions and turned up around a bead core in each bead portion from the inside to outside of the tire so as to form a pair of turnup portions and a main portion therebetween, and a bead reinforcing layer comprising at least one reinforcing ply of cords disposed of each said bead portion, wherein the turnup portion comprises a turnup main part extending an inner region ...

The heavy-duty garment hanger is a hanger of hollow stainless steel construction, which can hold heavy articles of clothing. The hanger is made from hollow filamentous tubing shaped into an upwardly projecting hook adapted to engage a structure allowing the hanger to hang and a body having shoulder portions extending generally outwardly from the hook and an elongated cross member interconnecting the shoulder portions. A second length of hollow filamentous stainless steel tubing may be inserted a...

In a process for converting C.sub.9+ aromatic hydrocarbons to lighter aromatic products a feed comprising C.sub.9+ aromatic hydrocarbons is contacted under transalkylation reaction conditions with a catalyst composition comprising (i) a first molecular sieve selected from the group consisting of ZSM-12, mordenite and a porous crystalline inorganic oxide material having an X-ray diffraction pattern including d-spacing maxima at 12.4.+-.0.25, 6.9.+-.0.15, 3.57.+-.0.07 and 3.42.+-.0.07; and (ii) a ...

A heavy duty tire comprises a carcass ply turned up around a bead core in each bead portion to form a pair of turnup portions and a main portion, and a bead reinforcing layer disposed in the bead portion and comprising an axially outer part and an axially inner part, wherein under a 50 kPa state of the tire in which the tire is mounted on a standard rim and inflated to 50 kpa: the turnup portion inclines towards the carcass ply main portion at an angle of less than 90 degrees; the distance La of...

A tire for heavy load use includes a carcass ply made of steel cords including ply turn-up portions that are turned up around bead cores from inside to outside in a tire axial direction. Each ply turn-up portion includes a turn-up sub-portion that is first turned up around the bead core and that extends in an inclined manner towards the ply main portion at an angle .theta., that is less than 90.degree., with respect to an outer surface of the bead core in the tire radial direction. The steel cor...

A heavy duty radial tire which is provided with traverse grooves extending between the tread edges and longitudinal grooves extending between the traverse grooves so as to form shoulder blocks arranged along each of the tread edges and inner blocks each disposed on the axially inside of one of the shoulder blocks. The longitudinal grooves between the shoulder blocks and the inner blocks have a depth Dga of 0.7 to 1.0 times the depth Dy of the traverse grooves, and the longitudinal grooves are ea...
