Novel powders useful in the slush molding process are produced by reacting an emulsion of either an isocyanate or an isocyanate reactive material with either an isocyanate reactive material or an isocyanate, depending upon the nature of the component used to make the emulsion in the presence of an at least partially blocked isocyanate and an organic carrier. The final reaction product is subsequen...

A means for ascertaining the health, or basic operational status, of a system unit. A "health check" provides an indication of either "yes", the system unit is operational, or "no", the system unit is either inoperative or there is a question as to whether the system is operational. The test is performed by requesting that the system unit perform a high priority "short" operation and noting the re...

A multi-processor system wherein two processors are connected through a dual port memory which receives from one of the processors an interruption request signal together with the data to be transmitted to the other processor. The dual port memory then generates an interrupt signal for the other processor so that the other processor can fetch the data from the dual port memory using an interrupt p...

A method of growing high purity diamond crystallite structures at relatively high growth rates on a temperature resistant substrate, comprising (a) flowing diamond producing feed gases at low pressure through a reaction chamber containing the substrate, the feed gases being comprised of hydrocarbon devoid of methyl group gases, i.e., acetylene or ethylene, diluted by hydrogen, and (b) while concur...

The present invention relates to method and apparatus for treating waste water, particularly metal-containing waste water. The process includes separating and removing metals and other impurities from the waste water by the sequential addition of a base, a polyelectrolyte and an acrylamide-containing copolymer dispersion. The purified water is recycled for continuous reuse while the small quantiti...

A hydrophilic microporous membrane, is provided comprising a hydrophobic membrane substrate exemplified by a polyolefin or partially fluorinated polyolefin membrane. A process is also provided for preparing a hydrophilic membrane by grafting a water soluble polymer to the hydrophobic membrane substrate surface by irradiation means, e.g., ultraviolet irradiation. The invention further concerns a me...

Normally hydrophobic fluoropolymer porous membranes having continuous pores are rendered hydrophilic by coating the pore interior with a mixture of at least one fluoroaliphatic surfactant and at least one hydrophilic but substantially water-insoluble polyurethane.

A method of forming synthetic diamond on a substrate is disclosed. The method involves providing a substrate surface covered with a fullerene or diamond coating, positioning a fullerene in an ionization source, creating a fullerene vapor, ionizing fullerene molecules, accelerating the fullerene ions to energies above 250 eV to form a fullerene ion beam, impinging the fullerene ion beam on the subs...

Crosslinked plasticized or unplasticized PVC products having gradient crosslinking density, with a high crosslinking density on the outer surface and a low or none crosslinking density at the bulk of the product, are prepared by immersing the PVC product in a hot water solution of a crosslinking material and a phase transfer catalyst. The products obtained provide controlled release of substances ...

The present invention relates to crosslinkable microfine ethylene copolymer powders which are substantially spherical in shape and range in size from about 10 up to about 500 microns and to the process of crosslinking the powders to reduce their melt flow rate. The powders are crosslinked by contacting with water in the presence of a silanol condensation catalyst at temperatures from ambient up to...
