Abstract: !     GEROTOR VACUUM PUMP                         David E. Hanson ABSTRACT OF THE DISCLOSURE            A unique gerotor-type pump is disclosed for pumping gases.  The pump has an inner gear-type rotor mounted within and rotating off-center with respect to an outer gear-type rotor ring, about a parallel axis.  Surfaces of the teeth of the inner rotor are in continuous contact with the outer rotor to define at least one pumping chamber which alternately expands and contracts as the inner and outer rotors turn.  An elongated inlet port is positioned to communicate with the pumping chamber during a substantial portion of the cycle when the pumping chamber is expanding, (the intake cycle) and an outlet port is positioned to communicate with the pumping chamber only just prior to and at the end of the contraction or exhaust cycle.  Oil for sealing and lubricating between moving parts of the pump is provided by employing differential pressure created by the pump's own opera-tion to draw oil through passageways which communicate between an oil reservoir and the pumping chamber.     !          !

Abstract: ABSTRACT OF THE DISCLOSURE             An apparatus and method for managing a livestock feedlot by early separation of poorly performing animals. Incoming animals are marked with an identifying number, then are weighed and the number and weight are recorded. At a selected later date the animals are indivi-dually directed through a walk-through scale. As the weight is obtained, it is immediately compared to the initial weight. If weight gain is below a selected standard, an indicator light is displayed and a gate into a "cull" pen is automatically opened. If weight gain is above the standard, another indicator light is displayed and a gate into a "retain" pen is auto-matically opened. Some livestock, no different from others in appearance or other characteristics, do not gain weight rapidly enough to be profitably fed in a feedlot operation. The above reweighing after a short feeding period has been found to be effective in eliminating poorly performing animals.          While the above method may be performed manually, greater speed, accu-racy and efficiency can be obtained where the different variables are sensed and entered into a computer system which can rapidly make the necessary calculations and comparisons to separate the animals on a continuous, rapid basis.

Abstract: EUKARYOTIC AUTONOMOUSLY REPLICATING SEGMENT                 ABSTRACT OF THE DISCLOSURE           Method, compositions and microorganisms involving host eukaryotic chromosomal DNA providing autonomous repli-cating segments (ars) joined to at least one gene capable of expression and replication in a eukaryotic host not naturally joined to the ars.  A eukaryotic chromosome is segmented and the segments joined to a gene capable of expression in a yeast and having a phenotypic marker allowing for selection to provide a hybrid DNA molecule. Yeast are transformed with the hybrid DNA molecule and cultured under conditions select-ing for the transformants, whereby the hybrid DNA molecules may be isolated providing a source of the autonomous repli-cating segment. The autonomous replicating segment may then be used in conjunction with one or more genes to transform the host or other eukaryotes to provide for multiple copies of a host gene, an exogenous gene, or for integration or recombination with the host chromosome, as well as expression of the gene(s).          This invention was developed under grants from the National Science Foudation, National Instiute of Health and the United States Public Health Service.

Abstract: B. Shelby - W. Moore 4-5 LATCH MECHANISM FOR LUMINAIRE                         ABSTRACT A latch mechanism for use in a street and roadway lighting luminaire. The latch mechanism operates generally in the same fashion as prior latch mechanisms to release the engagement between the upper and lower housings responsive to manual actuation of a pawl of the latch mechanism against the bias of a torsion spring. The present mechanism may be readily detached and replaced without the need for elaborate spring depressors. Two torsion springs are employed, one fitted to each side of the latch pawl to hold and bias the pawl. The springs can be released individually to enable removal of the pawl. On replacement, the pawl is slipped into the cast-in nesting arrangement with the two springs loosely fitted on the pawl. The springs are then depressed to their pawl-biasing condition to mount and affix the pawl to the lower housing. In this manner, the pawl can be replaced, if desired, without the need for tools of any kind, especially since the mounting of the latch in its housing is performed without screws or bolts.

Abstract: ABSTRACT      A homogeneous light-emitting hybridization assay is disclosed wherein light-labeled first and second single-stranded reagent segments are hybridized with a complimentary target single-stranded polynucleotide from a physiological sample such that non-radiative energy transfer occurs between the light labels of the two reagent segments.  At least one of the light labels is of the absorber/emitter type such that energy absorbed from the other light label is re-emitted as a different wavelength.  Such secondary emissions can only occur if hybridization has taken place and hence the presence of the target polynucleotide is related to the amount of secondary light emitted.

Abstract: ABSTRACT OF THE DISCLOSURE       A stereo receiver is described which is capable of receiving any two or more of the five currently proposed AM stereo system broadcast signals.  The multisystem receiver includes circuitry which is used in various configurations to demodulate the stereo signal components from broadcast signals of any one of two or more of the proposed systems.  Selection of appropriate elements of the receiver's circuitry for demodulating any one of the received signals is performed automatically in response to the detection of the presence of a corresponding pilot signal which is unique for each of the five different AM stereo systems that have been proposed.  The receiver includes apparatus which detects the presence of such pilot signals and controls the automatic switching of such receiver circuitry.  Also described is the application of such apparatus for reliably detecting the presence of the desired pilot signal in a single system stereo receiver.
