Abstract: A method of controlling fungus is provided which comprises contacting said fungus with a fungicidally effective amount of a compound having the following structure: ##STR1## wherein R is a halogen atom, andR.sup.1 is selected from the group consisting of substituted or unsubstituted, straight or branched alkyl having from about 1 to 6 carbon atoms,alkoxy having from about 1 to 6 carbon atoms,halo, provided that when any R.sup.1 is chloro, n is 2 and at least one R.sup.1 is meta-chloro,substituted or unsubstituted sulfamoyl, andsubstituted or unsubstituted carbamoyl,where n is 1 or 2.

Abstract: A method of controlling plant growth comprising applying to the plants or to a habitat thereof a herbicidally effective amount of a compound having the structure: ##STR1## wherein: R is selected from carboxy, carboxylate salt, carboxylate ester, formyl, halomethyl or a substituted methyl group capable of ambient oxidation or hydrolysis to a carboxy group, wherein the substituent on the substituted methyl group consists of an aliphatic group having a heteroatom containing group. The invention is useful in providing an alternative to known herbicidal methods and compositions.

Abstract: Certain pyrazolines have been found to be useful as aphicides and fungicides.

Abstract: A pyrazoline having the formula: ##STR1## wherein: R.sup.1 and R.sup.2 are selected independently from a group consisting of hydrogen with the proviso that only one of R.sup.1 and R.sup.2 can be hydrogen, substituted or unsubstituted alkyl of from 1-20 carbon atoms and substituted or unsubstituted aryl of 6 to 20 carbons, or R.sup.1 and R.sup.2 can together comprise the atoms necessary to complete a heterocyclic group of 5 to 6 nuclear carbon and hetero atoms;R.sup.3 and R.sup.4 are selected independently from a group consisting of hydrogen, substituted or unsubstituted alkyl of from 1-20 carbon atoms, substituted or unsubstituted aryl of 6-20 carbon atoms, alkoxy, alkylthio, cycloalkyl or heterocyclyl of 5 to 6 nuclear carbon and hetero atoms, or R.sup.3 and R.sup.4 together are an alkylene group of 4 to 5 carbon atoms.R.sup.

Abstract: An air filter assembly (1) includes an outer casing (6) having end, rear and downstream portions which are generally planular and thus easily settable on the floor during installation, with the downstream portion being mountable flush to a furnace (3) or the like. An inner filter-holding drawer (7) is provided for easy insertion and removal from the open front casing portion. At least one end wall (10, 11) of the casing is provided with a springable latch (34) adjacent the casing front opening and which snappingly engages and holds a cover (9)in place when the drawer is within the casing. The drawer end walls (44, 45) include external grooves (52) which slide over rails (56) correspondingly mounted internally of the casing side walls. The tolerances are such that the grooves are wider than the rails.

Abstract: A damper assembly for solar heating systems and the like includes a damper blade pivotably mounted to a peripheral main frame. The damper blade is surrounded by a peripheral flexible sealing element which extends inwardly from the surrounding frame and which is inclined in a direction against the direction of closing damper blade movement. As the damper moves toward a closed position, its sides progressively engage the side portions of the sealing element, with the latter providing a seal with the peripheral face of the blade. The ends of the blade engage the sealing element prior to the blade finally reaching its ultimate closed position, with the sealing being complete at the moment of engagement and throughout the final range of blade movement. The peripheral sealing element is mounted to a subframe which is adjustable on the main frame to thereby sealingly accommodate a warped damper blade.
