Patent number: 5115993Abstract: A motorized tape reel is carried on a mandrel shaft extending between a pair of brackets. At the first bracket, the mandrel shaft joins with a swivel ring which permits rotation and axial sliding of the mandrel shaft. The swivel ring swivels on vertical pins in order to swing the mandrel shaft out of its position between the brackets. A second shaft, journalled for rotation within the second bracket, has a power drive connection at its outer end and a separable coupling at its inner end for driving the mandrel shaft. A biasing spring at the first bracket urges the mandrel shaft towards the second bracket, thereby closing the coupling. To change tape reels, manual force is applied to the mandrel shaft to overcome the biasing spring and separate the coupling. The mandrel shaft is then swung out from between the brackets, and the old tape reel is removed. The reverse steps are followed to install a new tape reel.Type: GrantFiled: September 10, 1990Date of Patent: May 26, 1992Assignee: Cincinnati Milacron Inc.Inventors: Michael N. Grimshaw, Stephen J.

Patent number: 5089395Abstract: The present invention concerns a spectrometric technique to determine microorganism detection and identification by taking advantage of the inherent extracellular enzymes present in living organisms, as opposed to dead, non-enzyme producing organisms. These enzymes are harnessed in the in vivo reactions with a non-fluorescent dye containing a select organic functional group that is known to be cleaved or hydrolyzed by the certain enzyme. The dye is tailored such that one of the products fluoresces, so that by employing a conventional spectrofluorimeter, the rate of fluorescence can be determined. By subjecting a plurality of samples having different cellular concentrations of viable microorganisms to the same non-fluorescent dye, or by subjecting the same bacterial sample to a number of different non-fluorescent dyes, a pattern of fluorescent rates emerge.Type: GrantFiled: July 21, 1988Date of Patent: February 18, 1992Assignee: University of CincinnatiInventors: A.
