Granted: 2004-01-06
Abstract: Non-hazardous organic waste material is introduced through a line (7) into a slagging combustion chamber (11) where it is burned. The burning produces exhaust gases and a slag of molten, inorganic ash which is removed from the combustion chamber (11) by a line (12) connected to the bottom of the combustion chamber (11). The exhaust gases flowing out through line (13) are treated to remove most of the particulate matter contained in the gases. A portion of the treated gases is mixed with concentrated oxygen from air separation unit (38) in a proportion that results in mixed gases having an oxygen concentration of at least 30 % by volume. The mixed gases are then introduced into the combustion chamber (11) to support the burning of the waste material.

Abstract: This invention relates to elements such as birefringent crystals, which are used to separate a non-collimated input beam into two orthogonally polarized sub-beams or to combine two orthogonally polarized beams into a single beam. The optical device lessens or obviates the optical path length difference encountered in prior art devices and provides a polarization beam splitter / combiner that has substantially same optical path lengths for two split or combined beams propagating therethrough. Alternatively, the device is designed to provide a selected path length difference to compensate for polarization mode dispersion in other optical devices. The polarization beam splitter/combiner in accordance with the invention has a first uniaxial crystal having an o-ray path and an e-ray path and having the first port disposed at an end face thereof; a second uniaxial crystal having an o-ray path and an e-ray path, the e-ray path of the second uniaxial crystal being optically coupled with the o-ray path of the first uniaxial crystal and the o-ray path of the second uniaxial crystal being optically coupled with the e-ray path of the first uniaxial crystal. Alternatively, the axis of the second crystal is aligned in such a manner that the o-ray path is retarded by an extraordinary index of refraction of the crystal and the e-ray path is retarded by an ordinary index of refraction to equalize the optical path lengths.

Title: Implantable muscle stimulation device
Inventor: BUMM RUDOLF
IPC: A61N1/36
Filed: 2002-10-31
Granted: 2007-05-22
Abstract: A muscle stimulation device has a control unit (1) that determines frequency and/or intensity of electrical impulses in dependence upon the degree of stomach filling. The impulses function to stimulate lower esophageal sphincter (11) by means of stimulating electrodes (5a, 5b, 5c) disposed radially around the sphincter (11). A  computer program, executable by means of a microprocessor (10), is installed in the control unit, the program designed such that a higher stomach filling degree causes a stronger stimulation of the sphincter (11) or its substitute. The sphincter reacts to the stimulation by exerting a corresponding pressure onto a lower esophagus area (12). An increased risk of gastric reflux as a consequence of the patient's substantial food ingestion is countered by an increased stimulation of the sphincter, which in turn causes an elevated closing pressure at the lower esophagus (12). When the stomach is empty or nearly empty, the closing pressure is correspondingly reduced and the food ingestion is facilitated.
