Abstract: An apparatus is disclosed for an adjustable movable unit for a spiral separator seed cleaning machine. The apparatus may take a variety of forms depending on the particular spiral separator it is to be mounted upon. The movable unit mounts on a rod and is movable about that rod. Attached to this unit are one or more fingers which act as seed dams upon the inner flights of the spiral separator. The number of fingers corresponds to the number of inner flights. A set of these units attached to a rod is fixed to each half of the spiral separator. On the normal double spiral separator in use in most soybean seed cleaning operations, two sets of adjustable units consisting of four units each are required.

Abstract: An electronic sound generating system is disclosed for use with a stringed musical instrument such as a guitar. An RF oscillator is connected with an electrically conductive string of the instrument and a pickup coil is positioned adjacent to the string so that RF signals of varying amplitude are induced in the coil due to vibration of the string resulting from playing of the instrument. The variable amplitude RF signals are detected and an audio signal produced therefrom that is coupled to a speaker, for example. A stereo output can be provided by placing dual pickup coils adjacent to the string with the pickup coils being positioned normal to one another. Each string of the musical instrument can be separately provided with an RF current of a common frequency or different frequencies.

Abstract: A method for analysis of hemoglobin variants by high speed liquid chromatography and, more particularly, by ion-exchange chromatography. Through the use of high flow rates and pressures, the hemoglobin variants can be rapidly forced through the separation column to thus enable rapid analysis. A bonded phase inorganic support column is utilized for separation of the hemoglobin variants with the profiles thereof then being obtained. The bonded phase support preferably includes ion-exchange groups bonded through a carbohydrate intermediate to controlled porosity glass. A pair of different columns may be utilized to separate the hemoglobin variants with one of the columns being an anion-exchanger, and more particularly, a diethylaminoethanol glycophase, controlled porosity glass column, with the other column being a cation-exchanger, and more particularly, a carboxymethyl glycophase, controlled porosity glass column.

Abstract: A process and system for recovering the materials from an aqueous solution is disclosed. Dissolved materials in the aqueous solution are solidified as the aqueous solution is caused to be changed from liquid to vapor state, and the solidified materials along with suspended materials, if any, are collected. The aqueous solution is caused to be changed from liquid to vapor state at a filter which passes the vapor but blocks passage of liquid, and the filter has a vacuum at the side opposite to that of the aqueous solution so that the vapor is withdrawn through the filter and the solid materials collected on the filter. The system includes a thin film filter that is releasably clamped against a container so that one side of the filter contacts aqueous solution such as water in the container with a vacuum pumping device exerting vacuum pressure on the other side of the filter of less than about 4 mm of Hg. The system is particularly useful for determining impurities in water.

Abstract: A folding gooseneck trailer is disclosed having a positioning system for positioning the main bed of the trailer relative to the ground as well as the loading bed, or hitch platform, relative to the main bed and the ground. The loading bed of the trailer is pivotally mounted on the front end of the trailer main bed by a pair of spaced connecting links so that the loading bed can be raised and lowered relative to the main bed. The main bed has wheels at the rear end and, in the raised position, the loading bed holds the front end of the main bed off of the ground when the loading bed is mounted on the fifth wheel of a tractor, as by a king pin. A power mechanism is connected between the loading bed and a clevis plate attached to an elongated sliding element the lower portion of which terminates in a ground engaging foot. The sliding element is received in a channel in the main bed so that the sliding element is constrained to vertical movement in opposite longitudinal directions.

Abstract: A Kentucky bluegrass plant that is highly apomictic, thus providing a more uniform turf when propagated from seeds. The plant has good resistance to most diseases such as stripe smut, Helminthosporium leafspot, dollarspot, and rust. The production of a high number of rhizomes presents a dense turf which keeps weed competition down. This low-growing cultivar has a medium-textured turf and maintains its medium-green color for a longer season than some other varieties of bluegrass. The new variety of Kentucky bluegrass plant was selected from a large number of other bluegrass plants released in 1969 by Rutgers University to FFR Cooperative for variety development. The new variety was the result of replicated tests in cultivated areas at West Lafayette, Indiana and Spokane, Washington as reported hereinafter and the variety subsequently has been named "Plush".

Abstract: A Kentucky bluegrass plant which exhibits strong rhizome spread and thus predominates over other adjacent bluegrasses. The plant is a medium to light green color and this contributes to more drouth tolerance than dark green bluegrasses characteristically have. The new variety has moderate leafspot and powdery mildew resistance and is ideally suited for roadside use where competition from weeds is intense. The density and wear resistance of the new variety also make it useful for athletic fields, playgrounds, parks, and other surfaces where a high wear factor is involved. The new variety of Kentucky bluegrass was developed from clones originally discovered during 1952 among a collection of 24 bluegrasses taken from fairways of the Chicago Golf Club of Wheaton, Ill., in a cultivated area. The new variety was the result of six generations as reported hereinafter, and the variety has been named "Wabash". The instant plant was asexually reproduced by cuttings through succeeding propagations.
