There is provided a heavy duty tire made by using as a tread rubber a rubber composition obtained by compounding 100 parts by mass of a rubber component consisting of 90-30% by mass of (a) natural rubber and 10-70% by mass of (b) a solution-polymerized styrene-butadiene copolymer rubber containing tin in at least one of a middle of a polymer molecular chain and a terminal of the molecular chain and having a bound styrene content of 28-45% by mass and a vinyl bond content in a butadiene portion o...

A heavy duty tire including bead portions each with a bead core, and a carcass ply containing a main portion extending between bead portions and a pair of edge portions wound around the bead cores, the wound edge portion including a turnback part extending axially inwardly from a position on the axially outside of the bead core and an auxiliary cord layer disposed on the radially outside of the turnback part, whereby the end of the turnback part is positioned at a distance of from 2.0 to 8.0 mm ...

Disclosed is a process for the upgrading and demetallizing of heavy oils and bitumens. A crude heavy oil and/or bitumen feed is supplied to a solvent extraction process 104 wherein DAO and asphaltenes are separated. The DAO is supplied to an FCC unit 106 having a low conversion activity catalyst for the removal of metals contained therein. The demetallized distillate fraction is supplied to a hydrotreater 110 for upgrading and collected as a synthetic crude product stream. The asphaltene fractio...

In an over the highway vehicle, a frame including a pair of elongate frame rails and a plurality of cross members is disclosed. One of the rails includes an integrally formed bracket projecting laterally. The bracket is adjacent a rail aperture formed by cutting the one rail to define the bracket and after such cutting bending the bracket out of a plane of the one rail.

A heavy fishing line useful in fishing to reduce the environmental impact on marine birds has a high specific gravity and a high sink rate in water. The composite line has a central core of heavy metal and metal salt particles surrounded by a polymeric monofilament for use in long line fishing as well as fish nets.

A heavy equipment (such as a tractor loader backhoe) transporter is disclosed. The transporter apparatus includes a tongue assembly and a rear axle assembly. The tongue assembly is adapted to connect to the front of the heavy equipment and the rear axle assembly is adapted to connect to the rear of the heavy equipment. When the assemblies are connected to the heavy equipment, a new unitary trailer is formed.

The present invention provides a process whereby a high viscosity hydrocarbonaceous material is fed to a gasifier for conversion to synthesis gas. The feedstock, steam, oxygen, and recycled gasification system water are all fed into the gasifier through a four stream feed injector. The feedstock in this design is sandwiched between two oxygen streams so as to provide better conversion for the exceptionally heavy feed. The fourth stream down the central bayonet of the feed injector provides the f...

A stapler comprising a base defining a horizontal plane, a cartridge assembly coupled to the base at a cartridge attachment point, the cartridge assembly including a ram, and a lever arm pivotally coupled to the base at a lever pivot axis. The lever arm includes a grip for receiving a manual input from a user, and the lever arm is coupled to the ram at a ram input in order to provide a drive force. The stapler includes an inherent force factor, calculated as the horizontal distance from the leve...

A multi-pin electrical connector including a first connector portion and a second connector portion. Seal retaining rings snapped into the connector portions seal and retain cavity terminal blocks located within each respective connector portion. A locking collar employs a ramped locking feature to snap and secure the first and second connector portions in an interlocked, assembled state. The multi-pin electrical connector can be composed entirely of non-metallic components.

A heavy duty sawhorse brace comprising an elongated top horizontal channel, two elongated side leg channels and a brace plate. The channels are U-shaped and configured to receive the members used to construct the sawhorse. The channels further include at least one aperture configured to receive at least one fastener for removably attaching the sawhorse members to the brace. The brace plate extends from the top horizontal channel to each side leg channel, providing increased stability. The side l...
