Abstract: By utilizing Corynebacterium sp. N according to the present invention, massive amounts of the waste fluid containing high concentration ethanolamines can effectively be treated without causing an environmental pollution. According to the present invention, it is possible to treat the waste fluid containing ethanolamines in a small-scale manner. The apparatus for treating the waste fluid according to the present invention can readily be installed, and the initial and running costs such as a maintenance of the apparatus are inexpensive.

Abstract: A hydraulically operated continuously variable transmission comprising a hydraulic motor of the variable displacement type having a motor cylinder coupled to an output shaft and including motor plungers slidably disposed respectively in a number of cylinder holes defined in an annular pattern surrounding the axis of rotation of the motor cylinder, and a hydraulic pump coupled to an input shaft. The hydraulic motor and hydraulic pump are interconnected by a closed hydraulic circuit in which the flow of working oil is controlled by a distribution ring which is relatively rotatably and slidably held against an end surface of the motor cylinder for successively switching the introduction of working oil into the cylinder bores and the discharge of working oil from the cylinder bores in response to rotation of the motor cylinder. The distribution ring has an asymmetrical hydraulic pressure bearing area in order to minimize forces tending to tilt the distribution ring relative to the motor cylinder end surface.
