    摘要： A throughput-adjustable fluid-displacement machine includes a stator and a rotor which is supported on the stator for rotation about an axis. The stator has two axially spaced circumferentially extending cam tracks and the rotor has two sets of passages therein, each of the passages having an open end which always faces a different one of the cam tracks for each of the sets of passages. A plurality of pistons is respectively accommodated in the above-mentioned passages, each of the pistons having a cam follower portion and being acted on by a spring which urges the cam follower portion into a constant contact with the respective cam track so that the piston reciprocates in dependence on the configuration of the respective cam track. Two control sleeves, one for each of the sets of passages, is interposed between and selectively communicates the working chambers of the respective passages with respective input and output conduits of the machine. An angularly displacing arrangement is provided which displaces the two control sleeves simultaneously but in opposite directions whereby the throughput of the machine is adjusted while maintaining a substantially pulsation-free flow through the conduits. Preferably, the two control sleeves are displaced at the same angles in the opposite directions.

    摘要： Contaminated inactive mercury(II)chloride/active carbon-catalysts are worked-up. To this end the invention provides for the active carbon to be burnt with the quantity of air or oxygen or mixtures thereof necessary to produce combustion gases containing metallic mercury in vapor form together with between 0.5 and 5% by volume of oxygen and between 2 and 15% by volume of carbon monoxide; for the combustion gases to be contacted in a condensation zone with water so as to effect separation of the mercury therein; for the gases issuing from the condensation zone to be conveyed through a scrubbing zone having an alkaline liquor therein; and for the gases leaving the scrubbing zone to be delivered to the atmosphere.The apparatus for carrying out the process, which is comprised of a shaft furnace being provided in its base portion with a grate and with an ignition flap opening thereinto, and of a scrubbing tower being positioned downstream, in the direction of flow, of the furnace and receiving an alkaline liquor, is characterized in that the shaft furnace is provided in its base portion with a catalyst-supplying downpipe opening thereinto above the ignition flap; in that a condensation zone receiving water and terminating with its lower end in an outlet valve for the removal of mercury therethrough, is positioned between the shaft furnace and the scrubbing tower; and in that the upper end of the scrubbing tower terminates in a conduit running to the suction side of a fan.

    摘要： A process and device to detect and count yarn defects in a yarn segment including a camera (5), a computer (8) and an image processing program. The yarn (30) is illuminated with an intensity dependent upon the thickness of the yarn (30) and is photographed by the camera (5). The photographed image is digitalized in the computer with the image processing program and low-contrast points are filtered out. The remaining points are gathered together into coherent areas the sizes of which are classified into predetermined size classes and are stored.
