Abstract: A return roller assembly for the return flight of the continuous, driven belt of a bulk conveyor having a plurality of such return roller assemblies along its length. The return roller assembly comprises a central roller and a pair of end rollers. The central and end rollers are each rotatively mounted on its own shaft. Each roller shaft extends in a transverse direction with respect to the conveyor and the return flight of the conveyor belt. The central roller is mounted horizontally. The end rollers are mounted behind the central roller with their shafts in parallel spaced relationship to the central roller shaft transversely of the conveyor. Each of the end rollers has an inner end vertically aligned with an end of the central roller. Each end roller slopes downwardly and outwardly from its aligned inner end. The central and end rollers of the return roller assembly define a supporting shape for the return flight of the conveyor belt which accommodates the shallow, inverted, trough-shaped set of the return flight of the conveyor belt. The return roller assembly is mounted for slight pivotal movement about the vertical centerline of the assembly, so as to automatically maintain the return flight of the conveyor belt centered with respect to the conveyor.

Filed: 1994-09-26
Granted: 1999-05-11
Abstract: The invention is directed to biological processes and apparatus for determining the efficacy of a sterilization cycle based upon the recovery of activity of interactive enzyme systems comprising enzymes, coenzymes, catalysts, cofactors, substrates or any other necessary reagents. The invention provides a vital process for expediting sterility verification before utilization of the articles thought to be sterilized. The invention involves the rapid detection of any surviving interactive enzymatic activity which directly relates to the probability of any biological spores surviving in a test sample. An absence of a change indicates that the sterilization process had inactivated the enzyme system thereby preventing the interactive reaction from taking place which is a rapid equivalent to directly detecting the survivability of bacterial spores in a similar test. The methods and apparatus of the invention are useful in the health care industry such as in hospitals, laboratories, and research institutions, in food and environmental technology, and in all technologies which utilize sterilization in manufacturing, production or waste disposal.

Title: Differential expansion of fetal stem cells in the maternal circulation for use in prenatal genetic analysis
Inventor: ALTER BLANCHE P
IPC: G01N33/72
Filed: 1995-03-24
Granted: 2008-07-08
Abstract: The methods of the present in- vention use blood of pregnant females and fetal cell amplification to facilitate prenatal diagnosis without invading fe- tal space. This method is less invasive and simpler than amniocentesis or chori- onic villus sampling because it involves only drawing blood from the mother to obtain a fetal cell sample. If there is a specific disease with known molecu- lar mutations being sought, cells from the sample are a source of DNA en- riched for fetal material. If the disease is one involving red cells, this method provides fetal red cells for analysis. If the disease involves white cells, differ- ent cytokines can be used to selectively produce fetal leukocytes. When an ab- normal chromosome pattern without a specific diagnostic risk (e g., advanced maternal age) is being sought, then the culture method provides dividing cells of fetal origin.

Granted: 2007-01-09
Abstract: La présente invention concerne un circuit de balayage pour un ensemble de points de captage sensibles à la pression, et qui autorise l'ajustement de sa sensibilité. En particulier, on réalise un tel ajustement en contrôlant une tension d'essai et/ou de référence utilisée avec ce circuit, différentes sensibilités ou résolutions pouvant être obtenues pour différentes zones de l'ensemble. Ce circuit permet aussi une amélioration de l'isolement entre électrodes, ce qui permet d'utiliser une seule tension de contrôle pour balayer tous les points de captage sur une électrode d'entrée donnée. Ce circuit réduit davantage le temps nécessaire pour balayer l'ensemble en réduisant le temps de décharge de la capacité trace et en empêchant le traitement de points de captage qui ne sont pas concernés. La précision des pressions détectées est également améliorée grâce au réglage de la tension de contrôle visant à compenser les variations de charge.
