A power-assisted heavy lift chair comprises a base assembly. A chair frame is supported on the base assembly. A lift mechanism communicates with the base assembly and the chair frame, and is operable to actuate the chair frame between first and second positions. A transformer provides electrical power to an electric motor. The electric motor provides rotational power to the lift mechanism at a first rate to lift and/or lower the chair frame. The electric motor draws current from the transformer ...

An improved suitcase base and an improved pulling handle for use in a soft-sided suitcase and a hard-sided suitcase, giving the luggage, easy pulling characteristics. The base is nearly symmetrical in shape, with a V-shaped bottom wall forming an obtuse angle, which creates good ground clearance for the suitcase bottom under all conditions of towing over flat or uneven surfaces. Provision is made for securely latching the pulling handle while stored, and for quick, easy release from storage for ...

The invention provides methods and compositions for heavy metal phytoremediation, including plants which are genetically engineered to overexpress glutamylcysteine synthetase (ECS) and thereby provide enhanced heavy metal accumulation. In various embodiments, the plants comprise a gene encoding ECS operably linked to a heterologous promoter, the plant is a member of the Brassicaceae family. In general, the methods comprise the steps of growing such plants in a medium such as soil or water compri...

A device to move heavy items made up of a substantially flat rectangular body used to carry heavy items, a handle assembly with two handles perpendicularly attached to an H-shaped handle stand that is perpendicularly attached to the proximal end of the substantially flat rectangular body. A sling is provided on each handle of the handle assembly to hold long and awkward items extending from the substantially flat rectangular body. A wheel positioned at the distal end and center of the substantia...

A magazine loader comprises a magazine compartment (30), an elongated slideway (14) having a bullet and a case grooves (18, 22), respectively, along its length profiled to receive and retain the distal ends of rounds (50) between them, and a slider (40) slidable in slideway (14). A magazine (60) is positioned in compartment (30) such that its open end is perpendicular and in continuation to slide-way (14), and is leveled to receive rounds (50) slidable in slideway (14). Slider (40) is moved away...

A cart lifter is disclosed for lifting and inverting a refuse collection cart. The preferred cart lifter comprises a base and preferably has a lift member pivotally mounted with respect to the base for engaging the upper engagement surface of a refuse cart and a hook for capturing the lower engagement surface on the cart. An actuator is mounted to the base and is operatively attached to the lift member and hook for moving them between a lower and a raised and inverted positions. An actuator arm ...

This invention provides a heavy duty pinch valve for use in industrial applications, such as railroad tank cars that is constructed with a sealed housing that is sufficiently sturdy to operate in tough environments and large material flows. The valve includes a welded one-piece framework for sturdy support of pinch elements and the spool. The framework includes a tank car-connecting flange with two pairs of upright supports welded thereto. One pair of supports includes apertures for rotatably su...

A tire includes a radial carcass reinforcement radially surmounted by a crown reinforcement composed of at least two working crown plies formed of metallic reinforcement elements crossed from one ply to the next and forming with the circumferential direction angles of between 10 and 35.degree.. Also provided is at least one additional reinforcement, formed of at least two circumferentially oriented layers of metallic elements of a compacted diameter at most equal to 0.6 mm.

A low-viscosity, high-softening point heavy hydrocarbon material having a viscosity-reducing amount of at least one biodiesel material dissolved in a heavy hydrocarbon, and a method for producing such low-viscosity, high-softening point heavy hydrocarbon material are disclosed.

A water-insoluble polymeric oxidizing medium is contemplated that has a plurality of polymerized N-pyridinium vinylbenzyl triiodide or tribromide moieties whose pyridinium rings bear two substituents, R.sup.1 and R.sup.2, that are independently a hydrido or a C.sub.1-C.sub.4 alkyl group, and correspond in structure to the formula ##STR00001## A process for preparing aseptic water and an apparatus useful for carrying out that process, both of which utilize a contemplated polymeric oxidizing mediu...
