Abstract: A beehive for use in tropical environments is disclosed to be fabricated from plastic such as plastic foam and to have an elongated horizontal shape with a plurality of removable top cover/access plates and a bee entrance portal placed at a bottom corner of one of its elongated sides.

Abstract: Improved processes for polymerizing C.sub.3 -C.sub.12 olefins (e.g. propylene) comprising polymerizing olefins in the presence of a solid phosphoric acid catalyst and an alkanol. As well as catalyzing the polymerization, the catalyst also catalyzes the decomposition of the alkanol into water and olefin. The water in turn replaces water lost from the catalyst during the polymerization thus maintaining a more constant phosphoric acid strength catalyst without subjecting said catalyst to excess liquid water and substantially improving overall polymerization conversions and catalyst life.

Abstract: Sulfur cement-aggregate compositions such as sulfur cement concrete and mortars, comprising a sulfur cement and an aggregate and processes for preparing such products. The composition is characterized by the use of an expansive clay contaminated aggregate, which has been pretreated with a salt solution (e.g., KCl, CaCl.sub.2, etc.). The salt solution pretreatment substantially improves the water stability of the final sulfur cement and aggregate product.

Abstract: Sulfur cement-aggregate compositions comprising a sulfur cement and an aggregate containing an expansive clay and processes for preparing such adhesives. The processes, and resulting compositions, are characterized by adding a water soluble salt to the aggregate and then admixing said aggregate-salt mixture with molten sulfur cement. The resulting solidified composition has improved water stability.The compositions can be used as mortars or concretes depending on the particle sizes of the principal aggregate component.

Abstract: 1,2,4-Trisubstituted-1,2,4-triazolidin-3,5-dithiones are prepared by the reaction of a 1,2,4-trisubstituted 1,2,4-triazolidin-3-one-5-thione and phosphorous pentasulfide in the liquid phase. The triazolidin-dithione compounds are useful as herbicides and plant-growth regulators.

Abstract: An improved method and apparatus for bounce crimp texturizing thermoplastic yarn. The process and apparatus are characterized by a unique control system wherein either yarn thickness or a minute accumulation of the yarn discharged from the texturizer is sensed and the tension on the yarn controlled in response thereto so as to permit the yarn to issue from the texturizer in a loosely compacted tensionless state without significant intermediate yarn accumulation or piling prior to being continuously wound into packages.By eliminating substantial intermediate accumulation or piling of the yarn, the process and apparatus substantially reduce tangles, thereby reducing breakage and random crimpless lengths produced by the pulling on the yarn caused by these tangles.

Abstract: A method for increasing the rate of weight gain and feeding efficiency of a ruminating animal which comprises including captan, captafol, folpet, or mixtures of these compounds, in the animal's roughage feed allotment in a weight-gaining-effective amount between 1 and 200 parts per million, based on the daily roughage feed allotment for the animal. Preferably the compound is captan, and preferably the amount of captan included in the roughage feed is below 150 ppm.

Abstract: A novel process for making 3-(N-arylamino)-gamma-butyrothiolactones from their corresponding butyrolactone analogs is disclosed. The thiolactone products are useful intermediates for making fungicidal compounds.

Abstract: 3-(N-arylamino)-gamma-butyrolactones, butyrolactams and thiobutyrolactones are intermediates for compounds having fungicidal activity.

Abstract: An improved method and apparatus for texturizing thermoplastic yarn. The process and apparatus are characterized by a unique control system which facilitates accumulatorless operation and which allows two or more yarns to be texturized at the same time and wound on the same winder spindle. The control system is adapted to sense relative high and low yarn tension and to control tension to control wound yarn length to ensure that equal lengths of each yarn are collected (wound) on the winder spindle without over tensioning the yarn and without intermediate yarn accumulation.

Abstract: The growth of undesired vegetation is inhibited by applying to the locus where such growth is not desired an herbicidally effective amount of a compound of the formula ##STR1## wherein R.sup.1 is methyl or ethyl and R.sup.2 is phenyl; or phenyl substituted with 1 to 2 halogen atoms, 1 to 2 alkyl groups of 1 to 2 carbon atoms, or 1 to 2 alkoxy groups of 1 to 2 carbon atoms.

Abstract: A composition comprising 50 to 98 weight percent sulfur, 0.2 to 20 weight percent of an organic compound reactive with sulfur to plasticize sulfur, 1 to 40 weight percent mica, and 0.02 to 5 weight percent phosphorus sulfide. Preferably the organic compound used to plasticize the sulfur is dicyclopentadiene or a glycol. The composition is advantageously used to coat a concrete or metal surface and thereby obtain a coated surface which is resistant to acid attack and resistant to crazing on exposure to fluctuating temperatures.

Abstract: A method for killing wire worms and flea beetles which comprises applying to the soil habitat of the wire worms and flea beetles an insecticidally effective amount of a compound of the formula ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are alkyl of 1 to 4 carbon atoms; and X, Y, Z and V are sulfur or oxygen.
