perchlorate, potassium dichromate, cesium nitrate or potassium nitrate, and a second reactant serving as a reduction agent. When the reactants are activated they react to create solid particulate products having a diameter of about one micron or less which creates a smoke.
5588600 PROCESS AND APPARATUS FOR MAKING CRUMB RUBBER FROM VEHICLE TIRES Perfido Kenneth F; Cialone Anthony M Mount Sinai, NY, UNITED STATES
5588498
A process for recovering crumb rubber from used vehicle tires wherein the tires are comminuted in three cornminuting operations, the second and third of which are prefaced by contact with a liquid cryogenic. The cryogenic liquid which is gassified upon contact with the tire particles,is reliquefied and recycled.
ELECTRIC HYBRID VEHICLE Kitada Shinichiro Motor Co-Ltd
Tokyo, JAPAN assigned to Nissan
An electric hybrid vehicle has an engine for driving a generator to supply electric power to a vehicle driving motor. The engine with a catalytic converter is operated when a charged condition of a battery for mainly supplying electric power to the motor is low. The engine is controlled to suppress the amount of intake air by controlling an air control valve for a predetermined time after starting of the engine. The amount of the intake air is then gradually increased until the engine generates a rating output. Therefore, the emission characteristics of the catalytic converter is largely improved.
5588978 PROCESS AND APPARATUS FOR COLORING GLASS Argent Ronald; Bolin James A Green County, PA, UNITED STATES assigned to IMTEC A method and apparatus for the production of colored glass includes the steps of diverting a stream of clear molten glass from at least one glass melting furnace through one or more transport channels to a color treatment chamber. Recycled cullet and color additive are added to a charging end of the treatment chamber. The treatment chamber is heated to melt the cullet and further heat the remaining feedstock to form a molten bath of colored glass which is thermally and chemically homogenized in the treatment chamber. Refractory rotary paddle wheels positioned in the transport channels regulate the flow rate and level of the molten glass and provide for selective shut off of individual glass streams. A glass level sensor is located in an outlet channel of the treatment chamber and is electrically coupled to a programmable controller to selectively regulate the rotational speed of the paddle wheels responsive to glass level fluctuations to maintain a controlled gob weight of colored glass supplied to the glass forming machine.
5588599 METHOD OF MANUFACTURE OF POLYESTER-CHIP PRODUCTS FOR CASTING ARTIFICIAL-STONE ARTICLES Novak James P Tucson, UNITED STATES A method for preparing resin chips for use as an intermediate product in the manufacture of artificial-granite and artificial-stone articles. The process consists of mixing a thermoplastic polyester-resin material with an alumina t&hydrate (ATH) filler and with a pigment, if desired, in a heated extruder to produce a continuous stream of thermoplastic agglomerate. This product is allowed to cool, then it is cut, ground and screened to a predetermined size, as required to meet the size characteristics of the desired resin-chip product. The undersize fines produced by the grinding operation are recycled as thermoplastic feedstock to the extruder. The resin-chip material so produced may be further mixed with a filler, as required for a particular application, and packaged for sale to commercial users. 176

5589337 METHODS AIVDDIAGNUSTIC KITS FOR DETERMINING TOXICITY UTILIZING BACTERIAL STRESS PROMOTERS FUSED TO REPORTER GENES Farr Spencer B Longmont, CO, UNITED STATES assigned to The President and Fellows of Harvard College PCT No. PCDUS93/06537 Sec. 371 Date Jan. 6,1995 Sec. 102(e) Date Jan. 6, 1995 PCT Filed Jul. 6, 1993 PCT Pub. No. WO94/01584 PCT Pub. Date Jan. 20, 1994. This invention provides methods and diagnostic kits for determining the toxicity of a compound. The methods and diagnostic kits of this invention employ a plurality of bacterial hosts, each of which harbors a DNA sequence encoding a different stress promoter fused to a gene which encodes an assayable product. Each of these stress promoters is induced by exposure to a different type of cellular stress. The stress promoters utilized in this invention, in toto, comprise those promoters which respond to redox stress, DNA stress, protein stress, energy stress and pH stress. The methods and diagnostic kits of this invention may be employed to characterize and quantify the toxicity of a compound, as well as to identify the cellular mechanism of its toxic action. Moreover, the methods of this invention yield information concerning the action of a compound on a subcellular level. This information may be utilized to design antitoxins to compounds found to be toxic and in active drug design.
Sivakumar Ananthasubramania; Collins John H; Ramesh Mania Naperville, IL, UNITED STATES assigned to Nalco Chemical Company The invention is a process for removing color from a paper mill waste effluent containing color bodies which comprises: treating the waste effluent containing color bodies with an effective color-removing amount of a water-soluble silicon-containing copolymer coagulant prepared from diallyldimethylammonium halide and a vinyltrialkoxysilane; coagulating tbe color bodies present in the waste effluent; and then removing the coagulated color bodies from the waste effluent. The invention is also a waste water containing method for clarifying turbidity-causing compone& which comprises: adding to said water an effective turbidity-reducing amount of a water-soluble silicon-containing copolymer coagulant prepared from diallyldimethylammonium halide and a vinyhrialkoxysilane; mixing said copolymer and said water with a mechanical stirring device for sufficient time to allow flocculation of the turbidity-causing components; and then separating the flocculated turbidity-causing components from the waste water to obtain clarified water. Useful polymers for the practice of this invention are copolymers of diallyldimethylammonium halide and vinyltrialkoxysilane.
5592831 PROCESS FOR RECOVERING A PURE CARBON MONOXIDE FRACTION Bauer Heinz;Fabian Rainer Ebenhausen, GERMANY assigned to Linde Aktiengesellschaft In the recovery of a pure CO fraction from a charge containing hydrogen, carbon monoxide and methane from which water and carbon dioxide have optionally been removed, the charge is cooled and partially condensed; and the carbon monoxide is scrubbed out with supercooled liquid methane. The resultant hydrogen is stripped out, and the recovered CO/CH4-rich fraction is separated by rectification to obtain a pure CO fraction and a CH4-rich fraction. The supercooled liquid methane used as the scrubbing agent contains at least 2 to 15 mol % carbon monoxide, preferably 7 to 10 mol 96 carbon monoxide. Also, the hydrogen stripper and methane scrubbing column can be combined in a single column. J. Cleaner
