  • Patent number: 4775635
    Abstract: A system and method is disclosed for the rapid detection and (or) purification of analytes in a sample. The system makes use of a fluid receptacle containing a capture reagent and a manifold having two ports. A sample containing an analyte disposed within the fluid receptacle is subjected to a capture reagent and processed by inserting the open end of the receptacle in one port. Vacuum, gas, reagents, and wash fluids are then applied to the second port to effect rapid interaction between the capture reagent and analyte, efficient washing of the capture reagent and detection and/or collection of the analyte.The system and method provide a rapid safe, uncomplicated means of automating processes based on affinity complexation principles. Encompassed within this category of processes are immunoassays, nucleic acid hybridization tests and affinity separations.

  • Patent number: 4772074
    Abstract: A dual wheel mount assembly is disclosed which is particularly suited for heavy implements such as agricultural combines or earth moving equipment. Inner and outer wheels of the assembly are interchangeable and formed with circumferentially spaced mounting holes which are alternately of a smaller diameter and a larger diameter. Retaining nuts are threaded only on the mounting bolts in the smaller diameter holes in the inner wheel to operationally secure the same. The outer wheel is mounted so that the larger diameter holes therein fit over the retaining nuts for the inner wheel. Outer retaining nuts are operationally threaded on all of the bolts, including those securing the inner wheel. Removal of the outer wheel thus may be accomplished without affecting the securement of the inner wheel.

  • Patent number: 4771851
    Abstract: The present invention is a steering system for an articulated vehicle which has at least one axle mounted for wagon-wheel steering with respect to the vehicle, a hydraulic actuator for pivoting the axle with respect to the vehicle and a pair of hydraulic actuators for causing articulation of the vehicle. The improved steering system includes sensors for providing signals dependent on the degree of axle pivot relative to the vehicle, the degree of articulation of the vehicle and the desired direction of the vehicle travel. These signals are detected by a controller which in turn controls actuation of the axle and articulation hydraulic actuators. The actuators are operated in a sequential manner so that small directional changes of the vehicle are achieved solely through pivoting of the axle.
