Abstract: Vectors are described that circumvent traditional DNA cloning and subcloning procedures, and that contain a unique DNA cartridge that permits both cloning of DNA directly into DNA sequences present within the cartridge, and in vivo removal and circularization of the cartridge thereby yielding an autonomously replicating structure. Because the DNA cartridge can include a wide variety of functional DNA sequences, the cloned DNA can be subjected to a plethora of molecular biological procedures without having to remove the cloned DNA from the cartridge thereby obviating the need to perform additional subcloning technqiues. A particularly useful example of the this type of vector is bacteriophage lambda containing the DNA cartridge.

Abstract: An immunoassay device comprising a support which has a substantially planar surface 14 on which is located an array of small, closely-spaced, discrete, antibody coated areas (spots) 17. A cover 16 is spaced from the support surface 14 and is positioned over the array of antibody coated spots 17. The cover is attached to the support surface to provide an enclosed chamber 30. In the cover there is at least one aperture communicating with the interior of the chamber 30 for introducing a liquid sample into the chamber. In addition, there is at least one additional aperture 34 in the cover, which also communicates with the interior of the chamber to allow air to escape upon introduction of the sample into the chamber. When a cell sample is introduced into the chamber it immediately fills the chamber and cells will settle uniformly over the matrix. The antibody-coated spots function as tiny immunoadsorbents for cells bearing antigens recognized by the antibody. The device can be used to determine the proportion of cells in a sample cell population.

Abstract: The toothed wheel or gear rotates synchronously with the camshaft and is formed with contiguous circumferentially extensive zones of equal arcuate extent.  Each zone has a respective tooth and a respective adjacent notch. Certain of the teeth are of lesser arcuate extent than the remaining teeth and the corresponding notches are of greater arcuate extent then the remaining notches.  The smaller teeth occupy half the arcuate extent of the respective zone and the larger teeth occupy four-fifths of the arcuate extent of the zone.  These proportions provide optimum discrimination during normal operation of the engine using a Hall effect sensor (24) and microrprocessor to detect the various zones as the wheel rotates.
