Abstract: A device for supporting a patient is used with a computer-tomography (CT) device. The patient to be examined is to be introduced into an opening in a gantry of the CT device. The patient supporting device has a height-adjustable device disposed laterally with respect to the gantry opening and permits the height of a support for a patient to be adjusted. A support arm extends from the height-adjustable device to a fixture for supporting a stretcher and is rotatable with respect to the height adjustable device.

Abstract: Methods and apparatus are provided for positioning a plurality of cylindrical spirally wound membrane filtration elements in a body of aqueous feedstock employing manifold conduits that support vertically aligned filtration elements via short lengths of pipe. Efficient and effective connections are made between the ends of such support pipes and the adjacent end of each filtration element by bayonet-type fittings, which allow straightforward, detachable interconnection by axially moving the cylindrical element into place and then rotating the element a quarter turn. Support in this manner provides full access to the open lower ends of the element through which, during operation, streams of rising gas bubbles are caused to pass, fed from underlying bubblers or the like. The manifold conduits may be located either above or below the preferably vertically oriented filtration elements.

Abstract: High flow, low-pressure ultrafiltration or microfiltration spiral wound membrane cartridges are used in filtration of liquid feedstocks having high suspended solids. Applications may utilize either vacuum or pumping for transmembrane drive pressure (TMP), and gas may optionally be bubbled up through the cartridges with certain feedstocks. Water permeate flux rates as high as 90 gallons per square foot per day (gfd) can be obtained at TMPs below 5 pounds per square inch. By locating each spiral wound cartridge in its own casing and supplying liquid feedstock to an open lower end of the casing, as opposed to submerging such cartridges in a tank filled with feedstock, overall low pressure performance is greatly improved. High permeate flow can be maintained for long periods of time between shutdowns for intensive cleaning.

Abstract: An above table transillumination device has an X ray radiator that can be rotated around the horizontal axis of the radiator stand and that has a swivel lock having a manually actuatable unlocking lever. The unlocking lever is arranged at the front side of the radiator carrier facing away from the radiator stand and is connected to the lever of the swivel lock via a transmission device.
