A process for controlling temperature of a battery pack includes operating a fan to change a battery temperature to an optimal range of temperature (T.sub.opt) when a condition is satisfied that the battery temperature is equal to or greater than a maximum acceptable temperature (T.sub.max) or when the battery temperature is equal to or less than a minimum acceptable temperature (T.sub.min) and, at the same time, when the difference between a battery temperature (T.sub.bat) and an air temperatur...

A protective cover for covering vehicles or other objects comprises a rectangular sheet having both an elasticized perimeter and other elasticized portions which enable the cover to fit a wide range of vehicle or object sizes with which the cover is used to protect against paint or other environmental damage.

A polymer composition and articles fabricated therefrom is disclosed wherein the polymer composition comprises a low density polyethylene resin containing very small amounts of erucamide and oleamide. The composition is useful for forming article carriers and particularly useful for forming carriers for groups of metal cans which cans are subject to rotation in the carrier during use without significant injury to the carrier.

A plastic band is provided for encircling and combining into a single package, two multi-package assemblies of cans. The plastic band of the present invention encircles the outside of the array of cans comprising the combination of two multi-packages and further provides a central stabilizing strap which provides firm resilient engagement with at least all of the corner cans of each individual multi-package.

Coated articles, methods for making such articles, and waterproofing systems incorporating these. An exemplary coated article comprises a body with surface coating of inorganic particles reactive with hydroxide generated from hydration of concrete or mortar to form hydration products. The articles are designed to be used with cast concrete or masonry. The inorganic particles comprise at least one of (a) aluminum oxide trihydrate; (b) silica dioxide; (c) fly ash; (d) blast furnace slag, (e) silic...

A spacer for reinforcements has a body made of polymer concrete, with the polymer concrete consisting of a cured plastic material into which aggregates in the form of grains are integrated. The surface is post-treated in such a way that grains project from the surface of said cured plastic material, making possible an intimate chemical and physical bound with a cement paste of a concrete mass in which the spacer is to be embedded.

A supportive wrapping for a surgical support or orthopedic cast is produced by providing a bandage material which is impregnated or coated with a molten polyurethane polymer that is crystallizable in a predetermined, delayed time period at room temperatures or at temperatures tolerable to human skin and permitting the polyurethane polymer to crystallize on the bandage material to form a strong, supportive, self adhered wrapping while standing at or cooling to room temperature.

Disclosed are absorbent foam materials suitable for use as or in the absorbent cores of absorbent articles, such as diapers which absorb and retain aqueous body fluids. Such foam materials comprise hydrophilic, flexible open-celled structures which are preferably prepared by polymerizing high internal phase (HIPE) water-in-oil emulsions. Such foam materials have a pore volume of from about 12 to 100 mL/g, and a capillary suction specific surface area of from about 0.5 to 5.0 m.sup.2 /g. These ma...

Carrier stock formed from a single sheet of resilient polymeric material, such as low density polyethylene, and severable into individual carriers with integral handles. For each carrier, integrally joined band segments define container-receiving apertures. Moreover, an integral handle is joined at its ends respectively to middle portions of two outer segments, which are joined to one cross segment at a node. Stresses are distributed from each end of the handle, through the outer segment having ...

Carrier stock formed from a single sheet of resilient polymeric material, such as low density polyethylene, and severable into individual carriers with integral handles along lateral edges. Integrally joined band segments define container-receiving apertures. Perforate lines, along which such stock is severable, divide certain cross segments into half segments. Each half segment has an aperture-defining edge configured with a nub countering tendencies of such half segment to neck down or to brea...
