Abstract: A unique method for detecting and sampling flying insect populations is disclosed. An agricultural area is baited with a specific sex pheromone of a specific flying insect. When the flying insect is lured into range of the bait, a low-frequency sound is transmitted into contact with the insect. The sound is received in a counting means and the detection of the insect stored. Accumulated detections over a period of time form a population sampling of the insect studied.

Abstract: There is disclosed a process for esterifying resin acids and rosins by reacting quaternary ammonium salts thereof with an alkyl or alkenyl polyhalide for about 2 to 6 hours at temperatures between about 20.degree. C. and 90.degree. C. There is also disclosed novel di-esters produced by the process and the use of the process to reduce the acid number of incompletely esterified carboxylic acid components of rosins and resin acids.

Abstract: An automatic vegetable buncher for use in combination with a mechanical harvester of leafy green vegetables conveys the greens to a packing station where a pair of packer fingers driven by a novel rectangular motion generator incrementally feeds the greens into one of a plurality of pockets mounted on a rotatable wheel. When a predetermined bunch size is accrued, the wheel rotates to position an empty pocket at the packing station and to advance the vegetable bunch to a device which ties it into a marketable bundle.

Abstract: Alginate gel beads containing bioactive materials dispersed therein are the product and the process of this invention. These beads can be made to either float or sink in aqueous environments, and are capable of providing the controlled release of their bioactive materials when applied to terrestrial or aqueous environments.

Abstract: An apparatus and method for installing an extending plate earth anchor using extension plates, a hydraulic jack which works against the side of the wall, and techniques for load stress distribution are shown and described.

Abstract: A distributing device for solid particles of material, such as gravel, seeds, or similar material in the form of small solids to be delivered to containers. The device consists of a four-legged rectangular frame beneath which a rack carrying the containers may be positioned. The frame carries a rectangular bin in which an apertured fixed bottom plate and a similarly apertured top plate are fitted, the apertures of the bottom plate being longitudinally offset relative to the corresponding apertures of the top plate, with a slidable apertured middle plate disposed therebetween, operated by a manual lever arranged to move the middle plate from a receiving position with its apertures registering with those of the top plate to a discharge position with its apertures registering with those of the bottom plate. The rack holds the containers in a configuration such that the containers can be placed in vertical registry with the apertures of the bottom plate.

Abstract: A new apparatus for the application of liquid chemicals to soil is disclosed. A hand tool opens a slit in the soil by means of an injector blade and places a chemical-laden filament in the slit. The chemical-laden filament is dispensed from a floating spool in a fluid reservoir, through a conduit and to the soil. A handle provides both support for the reservoir and the injector knife as well as a working means for opening the soil.

Abstract: A high-pyruvate xanthan gum, substantially free of insolubles and undesirable coloration, is produced by fermentation of Xanthomonas campestris on a carbohydrate-containing nutrient medium having (NH.sub.4).sub.2 HPO.sub.4 at a level of at least 0.15% as the primary nitrogen source, and having a total phosphate level of at least about 0.25%.

Abstract: A ready-to-assemble kit for a solar air heater is provided including a heating chamber composed of a set of side-by-side elongated, hollow, straight ducts having openings at opposite ends thereof; wherein a manifold is placed at each end of the set, wherein each manifold is composed of an open-topped compartment and overlying lid, wherein the open-topped compartment includes a protruding lip adjacent the top, wherein the lip and overlying lid define an opening therebetween through which the set of ducts horizontally extend into the manifold. In the assembled kit, the heater and manifolds are disposed below a framed-in glazing which transmits solar energy to the heater.

Abstract: A method of producing reconstituted wood boards in a conventional press by introducing saturated steam through apertured press platens into a partially-compressed mat, composed of lignocellulosic material and a thermosetting resin binder, under specified conditions of mat density. Use of saturated steam in this manner allows production of a reconstituted wood board with shorter total press time than usual and with a more efficient use of energy. In addition total press time can be further reduced by injecting a gaseous catalyst into the mat to speed the cure of the thermosetting resin binder.

Abstract: An apparatus for sampling staple fibers containing foreign matter is disclosed. A clamping device is provided comprising upper and lower jaws pivoted with respect to each other. The upper jaw is segmented on one end to allow for localized deflection of the individual segments when foreign material is present. On the other end a spring assembly is provided to insure proper clamping pressure during and after the taking of a sample.

Abstract: Novel dibutylorthobenzylmethoxybenzenes having the structure ##STR1## wherein R is hydrogen, lower alkyl or lower alkoxy and novel dibutylorthocinnamylmethoxybenzenes are disclosed as growth inhibitors for mosquito larvae.

Alternaria cassiae is on deposit with the USDA-SEA-AR Southern Weed Science Laboratory in Stoneville, Mississippi; the Mycological Services, Botany Department, University of Massachusetts, Amherst; and with the Agricultural Research Culture Collection (NRRC), Peoria, Illinois and assigned the #12553.

Abstract: A method for UV (ultraviolet) fluorescence counting of selected biological masses, such as egg masses, on foliage samples comprising the steps of: exposing a foliage sample having attached egg masses to UV radiation by a scanning beam; discriminating between the fluoresced light due to the masses and the fluoresced light due to other biological or foliage components; and counting the egg masses based upon the fluoresced light emitted by the egg masses. Also, an apparatus for UV fluorescence counting of egg masses on foliage samples is provided comprising a sample feed means having a test chamber; combined electro-optical sample scanner, fluorescent light divider, and detector; and an electronic signal discriminator and counter for selecting the divided fluorescent light signals emitted by egg masses from the emitted light of other foliage components, to thereby provide a count of the egg masses.
