Title: Illumination system for variable direction of view instruments
Inventor: HOEG HANS DAVID
IPC: A61B1/06
Filed: 2006-01-25
Granted: 2010-04-13
Abstract: A illumination system for variable direction of view instruments is disclosed generally comprising an endoscope having a longitudinal axis and a variable view vector that pivots about a pivot axis angularly offset from the longitudinal axis. The view vector has an attendant viewing field that travels along a path as the view vector pivots, defining a viewing range. A source of illumination is arranged in a plane offset from the plane in which the view vector pivots and provides an annular, solid angle of illumination that covers the viewing range. In certain embodiments, the pivot axis is perpendicular to the longitudinal axis and the illumination plane is parallel to the pivot plane. In some embodiments, the source of illumination is a plurality of light emitting diodes arranged around the pivot axis.

Abstract: A process for preparing penicillin G procaine comprises the steps of introducing inactive ingredients into a first mixing tank and sterilising the mixture of inactive ingredients in the first mixing tank. A procaine hydrochloride is dissolved in a second mixing tank, and the contents of the second mixing tank are added to the first mixing tank through a sterile filter. A solution of penicillin G potassium is introduced to the first mixing tank through a sterile filter, and the contents of the first mixing tank are mixed so that the procaine hydrochloride reacts with the penicillin G  potassium forming penicillin G procaine. The resulting suspension is transferred through a homogeniser to a holding tank and penicillin G procaine is filled into a container.

Abstract: A method of recovering hydrocarbon or synthetic base oils from used oil-based drilling mud utilizes acid to deactivate emulsifiers in the drilling mud for altering the emulsion stability and permitting removal of the solids contained in the drilling mud using conventional separation such as centrifugation. A surfactant is typically added to prevent water-wetting as a result of the addition of the acid. The recovered base oil contains substantially all of the deactivated emulsifiers, which can be reactivated through the addition of lime, allowing new drilling fluids to be prepared without the need to add significant amounts of emulsifier to the recycled base oil.
