Abstract: An industrial grade mower that has a cutting blade rotating in horizontal plane under an inverted dish like housing that has a cuttings discharge opening in a side wall of the housing, and a easily removable mulch plate held in a dual channel receiver mounting system to cover and uncover the discharge opening respectively to mulch and discharge the cuttings. The mower discharge door or mulch plate attachment system is easily retrofitable to older mowers of the above mentioned design as well as capable of being included in a new mower design. The mulch plate is fitted with a handle that is used to easily install or remove it. The design of the handle allows it to act as a positive placement device which secures it at the proper height on the discharge of the mower deck. The present invention also incorporates a curved mulch plate which helps to keep the grass in motion which aids in cutting it into fine pieces before it drops to the ground.

Abstract: The present invention relates to a carboxylic acid based antifreeze coolant formulation for heavy duty applications such as for diesel engines which may be used for inhibition and prevention erosion and corrosion of aluminum and the corrosion of other metals exposed to an aqueous liquid in automotive coolant systems. The formulation further inhibits mineral scale. It may be packaged as an ethylene glycol based additive for use in new engines or in a concentrated inhibition package as an additive as for reinhibition of used coolant. The combination of a mixture of ethylene or propylene glycol, a monobasic carboxylic organic acid, azoles, low levels of molybdates, a nitrite salt and/or nitrate salt and/or siloxane stabilized silicate, and combinations thereof, polyvinylpyrrolidone, provide a synergistic protective effect against the cavitation corrosion of aluminum in aqueous liquids reducing the corrosion rate and is effective at relatively low concentrations and varying pH ranges.

At least one end of the cross bar is detachably connected to the frame arm associated therewith by a means for connecting such as a snap fit.

Abstract: A water based spray wax composition containing a microemulsion of a cationic wax nanoparticles, a quaternary silicone compound and zinc oxide nanoparticles providing long lasting protection of paint, glass, and metal, plastic, rubber, or elastomeric trim surfaces. The use of microemulsions or nanometer sized particles in the primary ingredients provides a transparent spray wax composition, which provides excellent coverage due to a significantly larger surface area, due to the nanoparticles used in the formulation. It also enables the wax particles to penetrate and fill small cracks and crevices for improved appearance, and durability of the spray wax properties.

Abstract: A wax composition for application to a wet surfaces utilizing a polymeric emulsion with a cross-linked copolymer of acrylic acid and C10-30 alkyl acrylate whereby upon application to the surface to be waxed the hydrophilic portion of the polymer instantly collapses releasing the oil phase and providing immediate coverage of the application surface forming a film upon drying, and buffing the waxed surface with an absorbent material leaves a protective coating of wax of the surface which does not easily re-emulsify or wash off when further exposed to water.

Abstract: The present invention provides a liquid protectant composition composed of a cationic microemulsion of a natural wax (carnauba wax) nanometer sized particles and zinc oxide nanometer sized particles in combination with a quaternary siloxane compound. The protectant composition of the present invention cleans, protects preserves and enhances the appearances of leather or vinyl surfaces used for covering items in the home or in vehicles. The product is easy to apply to both smooth and textured surfaces and has a transparent appearance. The product dries quickly and does not leave an oily residue. Utilization of nano technology to select components having nano sized particles provides a uniform deposition of the product leaving a thin film having exceptional protection properties. Unlike conventional protectants, the invention of the instant composition dries quickly and leaves no oily residue behind.

Abstract: A fluid media such as oil or water, and a selected effective amount of carbon nanomaterials necessary to enhance the thermal conductivity of the fluid. One of the preferred carbon nanomaterials is a high thermal conductivity graphite, exceeding that of the neat fluid to be dispersed therein in thermal conductivity, and ground, milled, or naturally prepared with mean particle size less than 500 nm, and preferably less than 200 nm, and most preferably less than 100 nm. The graphite is dispersed in the fluid by one or more of various methods, including ultrasonication, milling, and chemical dispersion. Carbon nanotubes with graphitic structure is another preferred source of carbon nanomaterial, although other carbon nanomaterials are acceptable. To confer long term stability, the use of one or more chemical dispersants is preferred.

Abstract: This invention presents a process to produce bulk quantities of nanowires of a variety of semiconductor materials. Large liquid gallium drops are used as sinks for the gas phase solute, generated in-situ facilitated by microwave plasma. To grow silicon nanowires for example, a silicon substrate covered with gallium droplets is exposed to a microwave plasma containing atomic hydrogen. A range of process parameters such as microwave power, pressure, inlet gas phase composition, were used to synthesize silicon nanowires as small as 4 nm (nanometers) in diameter and several micrometers long. As opposed to the present technology, the instant technique does not require creation of quantum sized liquid metal droplets to synthesize nanowires. In addition, it offers advantages such as lower growth temperature, better control over size and size distribution, better control over the composition and purity of the nanowires.

Abstract: A device to facilitate manipulating a key by persons having restricted finger and/or hand use that includes a key holding unit with a socket in one end thereof and means to removably secure a key to such unit. The device also includes a hand tool that has a hand grippable body portion with a rounded outer surface in which there is located finger engageable indentations. The indentations are spaced apart from one another around an outer peripheral portion of the body to facilitate gripping and turning the same. A shaft projects outwardly from the body a terminating in a rounded bullet like free outer end that facilitates inserting the same into the socket in the key holding unit. The shaft has a portion proximate the rounded end that is non circular in outline cross sectional shape that is matingly insertable into the socket in the key holding unit. For those having limited hand movement there is provided a reversible ratchet between the hey holding unit and the hand tool.
