Inventor: VATER JOACHIM
IPC: C07K7/06
Filed: 1997-08-11
Abstract: The invention relates to an extremly efficient inactivating process for lipid envelopped virus such as Herpes virus and retrovirus in - mainly pharmaceutical - biological or biotechnological products and in cell cultures, wherein a cyclical lipoleptide or a lipopeptide mixture or salts or esters thereof are added in certain concentrations. It appeared that lipopeptides have a surprisingly strong inactivating power on lipid envelopped virus and the additionnal advantage of very low vivo-toxicity, such that eliminating the inactivation agent in pharmaceutical products would no longer be necessary. The invention relates also to new antivirus lipopetides pertaining to the surfactine group.

IPC: F16K1/226
Filed: 1999-06-25
Abstract: A repair of a butterfly valve having metal seat includes de-watering of the valve, and movement of the disc to the open position. As in the prior art, the extant (usually brass) valve seat is machine in situ and capped with a stainless steel substitute seat having relatively low slope in the range of 10° to 20° with respect to the closing valve disc. The valve disc edge and valve disc edge caps are removed. A new valve flap seal clamp and relatively hard rubber seal (in the range of 70~5 shore) is inserted. The new valve seal edge clamp has a profile to completely capture the inserted rubber valve seal edge and assure that all elastic extrusion occurs only to and toward the refurbished valve seat.  This elastic extrusion necks down and decreases in cross-section toward the edge of the disc of the valve. When the clamp is compressed, the elastic section of the rubber valve seal is extruded to extend to and toward the valve seat. This extension by extrusion occurs along an axis, which axis is at an obtuse angle with respect to the refurbished seat on the high-pressure side of the valve disc.
