An adjustable counterweight for use on construction vehicles that includes a body having a first section, a central section adjacent to the first section and a second section adjacent to the central section, wherein the first section and the second section each define a cavity therein. At least one weight plate, preferably a plurality of weight plates, is mounted in a predetermined position within each of the cavities and secured to the body of the counterweight. Each weight plate is shaped to f...

The road-towed heavy-load ferry may be produced in larger or smaller versions using the same design. Its basic embodiment can transport afloat loads exceeding 16 metric tons (17.6 tons) including its tow vehicle. The ferry essentially comprises three longitudinal hulls. Outboard hulls (12) pivot outward and inward to rest atop central hull (10). Thereby, the ferry is reduced to a width suitable for towing on public roads. Equipment for road towing includes telescoping towing tongue (32), and pne...

A catalyst composition for the cracking of heavy oil, which has high cracking activity for heavy components in the heavy oil and features reduced deposition of coke. The catalyst composition is comprised of a zeolite, a mixed metal oxide, clay and a metal oxide, and the total acidity of a portion of the catalyst; the portion being composed of the catalyst components other than the zeolite, is from 0.02 to 0.08 mmol/g.

The cable puller uses a compound handle to create great leverage in order to generate a large pulling force with a minimal amount of force applied by the operator. The pulling force can be used for heavy lifting applications. The cable puller could be used to hoist motors, shafts, gears, automobile engines, construction material, machinery and other heavy objects. The cable puller could also be used in the demolition of building structures, the erection of buildings and towers, straightening col...

A slider and method of using the same is provided for facilitating the sliding of a load on a supporting surface. The slider includes a support platform having an upper surface for receiving the load thereon and a lower surface. A plurality of slider elements depend from the lower surface of the support platform. Each slider element has an outer surface engageable with the supporting surface. A lubricating pad extends from the support platform and is engageable with the supporting surface for lu...

A tool for dislodging lubrication-blocking debris from machinery elements. A housing includes a forward internal chamber. An adapter receives an explosive charge element and completes the chamber. The adapter includes an exteriorly-threaded portion for affixation of the tool to a lubrication access hole. A firing mechanism is positioned and spring loaded at a rear chamber of the housing. In use, the tool is inserted in place of a grease nipple and the explosive charge element detonated, for exam...

A method is provided for conversion of heavy alkylaromatic compounds, particularly those in the C.sub.8 -C.sub.12 range, into more valuable aromatics of benzene, toluene and xylene utilizing a toluene disproportionation unit containing a nickel, palladium or platinum-modified mordenite catalyst. The method allows large amounts of these heavy alkylaromatic compounds to be processed without adversely affecting catalyst activity or catalyst life. This is accomplished by introducing the heavy alkyla...

A heavy oil remover comprises d-limonene, dipropylene glycol mono n-butyl ether, a salt of an alkyl aromatic sulfonic acid, a carboxylated anionic detergent, an ethoxylated tallow amine, a branched alcohol ethoxylate, an ethoxylated alkyl mercaptan, and water.

A heavy duty display hook which supports point of purchase items or packages is insertable into a rectangular aperture of a panel, such as a cardboard panel provided with a number of spaced apertures for display hooks. The display hook includes a front plate which is substantially vertically disposed in use and which has an upper end and a lower end and an elongated support member which projects forwardly from and extends upwardly in slightly inclined fashion to the front plate. A pair of arms e...
