Abstract: This invention relates to isolated polynucleotides encoding a wheat glutathione transferase subunit (GST) as well as host cells and plants transformed therewith. The invention also relates to methods of using the isolated polynucleotides to make herbicide resistant plant cells and plants, and to methods of selecting transformed plant cells in the presence of an herbicide.

Abstract: An under booth paint collection apparatus is positioned beneath a paint application booth that includes an air circulation system for painting a product with particulate paint. A plurality of discrete powder reclamation collectors are arranged in aligned rows beneath the booth. Continuously aligned air chambers are each positioned above one of the opposing rows of reclamation collectors. Each air chamber is defined by having opposed continuous side walls interconnecting said reclamation collectors. Each air chamber provides a continuous air plenum directing air and particulate paint not adhered to the product being painted from the application booth to the plurality of discrete reclamation chambers.

Abstract: An apparatus for chemically treating a metal part which includes an immersion tank containing a liquid chemical treatment solution, a conveyor conveying parts over the immersion tank, immersing and removing the part and at least one spray nozzle assembly located above the immersion tank which is supported on a track extending to a side wall of the tank and permitting maintenance of the spray nozzle assembly without draining the tank.

Abstract: A spray clean stage of a pretreatment system for treating a product surface having contaminants includes a tank for holding a cleaning solution to clean the product surface. A solution applicator is in fluid communication with the tank through an applicator inlet. The solution applicator is oriented to spray the solution onto the product surface thereby removing the contaminants from the product surface. A partition at least partially covers the tank and receives runoff of the solution from the product surface being sprayed with the solution. The partition is oriented to direct the runoff of solution from the product surface into the tank at a location spaced from the applicator inlet to distance the contaminants removed from the product surface from the applicator inlet.

Abstract: A discrete pod gas scrubber system for removing contaminants from the air of a work area, such as a paint spray booth. Each scrubber pod includes an inlet section having opposed converging planar walls and side walls, an intermediate section having opposed diverging walls and side walls communicating with the inlet section through a reduced diameter venturi, and an outlet section having a bottom wall perpendicular to the longitudinal axis of the scrubber pod, a diverging top wall and an end wall. The end wall includes an orifice opening and orifice plates for adjusting the orifice opening and the combined lengths of the aligned scrubber pods are between fifty and ninety percent of the total length of the scrubber system, more preferably between sixty percent and eighty five percent of the total length. The scrubber system of this invention significantly reduces the noise generated in the work area normally located above the gas scrubber system.

Abstract: A method of detecting the metastasis of primary breast cancer to a lymph node is provided, comprising detecting, in lymph node tissue, the presence of a nucleic acid of c-myc, PIP or keratin-19. The presence of any one of these nucleic acids in lymph node tissue is associated with metastatic breast cancer. The presence of one or more of these markers in lymph node tissue or other tissue indicates that cells from the primary tumor have migrated from the breast tissue to the lymph node or other tissue. Also provided is a method of predicting the histopathologic stage of a cancer in a patient without having to perform a histopathologic analysis, comprising detecting, in lymph node tissue from the patient, the presence of a nucleic acid of c-myc, the presence of a nucleic acid of c-myc being correlated with stage I cancer as determined by histopathology.

Abstract: An air supply plenum for a paint spray booth includes a housing with separating walls positioned between the ceiling and a filter support panel of the plenum housing. The air flow supplied to the paint spray booth area is divided by the walls into three distinct flows: (1) a central flow air, through which the article to be painted travels in the paint spray booth, (2) two outer greater flow areas where the operators and/or equipment for applying paint to the article to be painted are located. Filters are positioned in the supply plenum arrangement adjacent and above the filter support panel separating the plenum and paint spray booth. The filters run longitudinally along the length of the plenum and between the separating walls. The positioning of these filters in this manner minimizes the amount of turbulence of the flow provided to the spray paint booth.

Abstract: An improved gas scrubber system is disclosed in which air from a paint spray booth is mixed with a liquid to remove paint particles and other contaminants in the air. A wall is positioned immediately downstream of an outlet of the gas scrubber and a jet of intermixed water, entrained contaminants and air impinges off of that wall, to separate the majority of water and contaminants. The gas scrubber member has a unique structure such that the air and water are directed through a first portion generally aligned with an inlet and into a second portion which extends at a 90.degree. angle with respect to the first portion. A restriction is formed on the first portion to provide a noise barrier. The gas scrubber member is formed by planar walls to ensure that the water continues to adhere to them under surface tension, and in essentially laminar flow, while in the first portion. A top wall is spaced from a base wall to define the second portion.

Abstract: Tellurium and selenium dialkyls are prepared by reacting the corresponding tetrahalide with a Group I metal alkyl.

Abstract: A load sensor which has an elongate hollow body 11, preferably formed as a metal extrusion, and which forms a first capacitative plate 21. A second parallel capacitative plate 15 is formed on an insulating body which is held in place relative to the extrusion by a resilient support 16. Application of a load to the extrusion causes variation in the gap between the plates of the capacitor, thus affecting the capacitance in a manner which is measured and processed to provide an output signal which is directly proportional to the applied load.
