A composition for being sprayed on the foliage of a plant, which is suspended in water so as to apply to the foliage of the plant by using a paint sprayer or the like, which provides the effects that the photodecomposition of water on the surface of the foliage is advanced, and thereby carbon dioxide assimilation in the plant can be expedited, and an oxygen free radical as produced in a process of a photodecomposition reaction of water can be used for a lipid peroxidation reaction in a plant cel...

Blends of diaminoisopropylbenzene (DAIPB) and diaminoethylbenzene (DAEB) are provided for curing epoxy resins. The cured epoxy resins have increased tensile strength and slightly lower glass transistion temperatures as compared with resins cured with either diamine alone.

Novel substituted pyrazolo-rings fused to nitrogen containing heterocyclic rings having the following formula ##STR1## in which at least one of Y, Z or W is N or N-O and the remainder of Y, Z or W is C-R wherein the variables are as defined in the specification; and agriculturally acceptable salts thereof.

This invention relates to an improved method for curing polyepoxide resins at elevated temperature and particularly to a method for reducing the time required to effect cure of thermosetting resins at elevated temperature without sacrificing performance. In the basic process, an epoxide resin comprising a polyglycidyl ether of a polyhydric phenol is mixed with cycloaliphatic amine, e.g., di(4-aminocyclohexyl)methane, di(4-amino-3-methylcyclohexyl)methane, and isophoronediamine in an amount suffi...

A flow control structure which is primarily intended to be utilized as a pressure compensating emitter in agricultural watering or irrigation can be constructed utilizing a housing having a flow control member located therein. The housing employed has an internal cylinder connected by a passage leading to a valve seat. The flow control member extends from the cylinder to adjacent to the valve seat. The extremity of the flow control member within the cylinder is formed as a piston so that the flo...

The present invention relates to novel pyrazolyl-substituted heterocycles of the formula (I) ##STR00001## in which X, Y, Z and Het are as defined in the disclosure, to processes for their preparation, and to their use as pesticides, microbicides and herbicides.

A spray paint shield for manually protectively covering a portion of a wall or ceiling when the adjoining ceiling or wall portion, respectively, is being sprayed painted. The spray shield includes a generally flat, elongated sheet of thin, flexible material such as stainless steel or aluminum, having a straight distal or working edge and an elongated handle pivotally connected to, and extending from, the flat sheet at a mid point of the edge of the flat sheet opposite its distal edge. The handle...

The present invention relates to novel pyrazolyl-substituted heterocycles of the formula (I) ##STR00001## in which X, Y, Z and Het are as defined in the disclosure, to processes for their preparation, and to their use as pesticides, microbicides and herbicides.

Self cleaning mixtures that use photoactive agents with varying oxides, along with mixing the photoactive agents with carbon, noble metals and cobalt phosphide that inhibit the growth of algae are disclosed. The agents include concentrations of approximately at least 5% to approximately 50% TiO.sub.n1, WO.sub.n2, X--WO.sub.n2, or X--TiO.sub.n1, where 1.8.ltoreq.n1.ltoreq.2, and where 2.2.ltoreq.n2.ltoreq.3, and where X can be one of carbon, a noble metal, and cobalt phosphide. The agents can be ...

Epoxy resin compositions containing polyepoxides having at least two 1,2-epoxide groups are disclosed. The polyepoxides can be obtained by reacting (i) di- or polyepoxides or mixtures thereof with monoepoxides, (ii) one or more amines chosen from sterically hindered amines, disecondary diamines and diprimary diamines to form an epoxide-amine adduct, and (iii) subsequently reacting the epoxide-amine adduct with polyfunctional isocyanates. The composition also contains curing agents for the polyep...
