Abstract: SPLINED CLUTCH DRUM MOUNTING  Abstract of the Disclosure An oil passage connection between a shaft and a clutch drum is sealed by intentionally providing an imbalance in the forces acting on splines mounting the clutch drum to the shaft.  The sides of at least some of the splines are angled, so that at least some part of any torque applied between the clutch drum and shaft is resolved into radial components.  By providing a differing number of splines, or an asymmetrical positioning of the splines, the net force can be designed to force the sides of the shaft and the clutch drum adjacent to the oil passage tightly together.  This is most easily accomplished by simply omitting one or more splines from the clutch drum on either side of the oil passage.  With such a structure, the same splines on the shaft can be used to mount gears and the like, which normally require symmetrical distribution of forces.

Abstract: The detection of bacterial growth or the performance of other interrogative processes in multiple sample vials is accomplished using a moving rack that selectively couples optical locations to an optical excitation/detection system. The apparatus includes a drive mechanism combining agitation of the culture vials with a sequential scanning of an array of optical fibers, preferably by a spectrophotometric excitation/detector system.      Selection of each culture vial provides, for example, optical detection of bacterial growth by fluorescence or other spectrophotometric measurements. A rack for holding vials is preferably the only moving assembly, and requires no mechanical or electrical interconnection with the excitation/detection system for its operation. In general, the present invention relates to the optically indexed presentation of the optical guides, e.g., the emission and excitation fibers, to many remote sample sites in the form of a geometric array at the interface between the moving culture vial rack assembly and the spectrophotometric excitation/detection system fixed to the body of the instrument. Methods of transmitting and receiving electromagnetic radiation to and from sample vials held in a movable rack include the steps of coupling the sample vials to an optical fiber and terminating the optical fiber at an optical coupling location. The rack is then moved to align at least one of the coupling locations with an excitation/detection system.

Title: An animal feed additive based on fermentation broth, a process for its production and its use
Inventor: BINDER WOLFRAM
IPC: C12P13/22
Filed: 1994-03-16
Granted: 2008-01-08
Abstract: Animal feed additives based on fermentation broth contain other fermentation broth ingredients in addition to the additive. After spray drying, such products generally have an inadequate apparent density and/or are tacky. Accordingly, auxiliaries such as for example, perlite or sawdust are added for pelletizing of the products. Alternatively, the products are freed from water by azeotropic distillation with paraffin oil to form pellets. The problem addressed by the invention was to provide a highly concentrated animal feed additive which, in particular, was to have an apparent density of at least 550 kg/m3 and a standardizable active-substance content. Stable pellets can be produced by pelletizing from a fermentation broth containing an animal feed additive when at least 33% by weight of the fermentation products are present. The pellets can be produced particularly effectively by pelletizing providing they are built up from at least 30% by weight of fine particles of which at least 70% by weight are smaller than 100 µsize. The biomass may be completely present, partly present or not present at all in the pellets. Animal feed additives, such as lysine, threonine or tryptophane, all containing fermentation broth products.
