Abstract: An alternating pressure mattress has two sets (A, B) of cells, which are inflated and deflated cyclically and in sequence, to provide alternating support for a patient. Each set (A, B) has central transverse cells (11a, 11b) and side forming cells (14a, 14b). The central cells (11a, 11b) provide a central region for the patient. The side forming cells (14a, 14b) protrude, when inflated, higher than the central cells, to act as side barriers preventing rolling of the patient off the mattress. At each side of the mattress a plurality of the side forming cells (14a, 14b) of both sets (A, B) is present, these cells inflating and deflating with the respective central cells (11a, 11b), so that the side barrier effect is provided by the two sets (A, B) cells alternatingly.

Abstract: The present invention relates, in general, to attenuated negative-strand RNA viruses having an impaired ability to antagonize the cellular interferon (IFN) response, and the use of such attenuated viruses in vaccine and pharmaceutical formulations. The invention also relates to the development and use of IFN-deficient systems for selection of such attenuated viruses. In particular, the invention relates to attenuated influenza viruses having modifications to the NS1 gene that diminish or eliminate the ability of the NS1 gene product to antagonize the cellular IFN response. The mutant viruses replicate in vivo but demonstrate reduced pathogenicity, and therefore are well suited for live virus vaccines, and pharmaceutical formulations.

Abstract: The actuating device has a vertically displaceable trigger (9) which is mounted on a hood-shaped housing part (6a) of the drain valve (3). A lever (2), whose horizontal axis of rotation (5) is mounted on a float housing (6b), is pivoted with the trigger (9) in one or the other direction of rotation. To induce flushing, the trigger (9) is moved in the downward direction with a release knob (1) against the restoring force of a spring (24). The trigger (9) now engages a pivotable arm (9b), and the lever (2) is pivoted such that a valve tube (4) connected to the lever (2) is raised, and the valve opening (11i) is thus opened. If the release knob (1) is moved once again in the downward direction after a partial flushing, the trigger (9) will engage another pivot arm (2a), and the lever (2) will again be pivoted into the starting position, in which the outlet opening (11i) is closed.

Abstract: Nails are driven into hard receiving materials such as concrete, rock, metal and the like by explosive powder charge operated setting tools. To achieve the high mechanical strength required for such nails, the nails are formed of two parts, one a shank and the other a head fitted onto the shank. While the head is formed of a deformable corrosion resistant steel, the shank is formed of an austenitic steel alloyed with nitrogen having a very high mechanical strength. The steel forming the shank can only be shaped to a very limited extent, whereby a narrow flange is provided on the rear end of the shank. A disk fitted on the shank serves as a guide for the nails during the driving operation.
