The use of dsRNA for the mfr. of a medicament to treat a dsRNA-deficient disease state, excluding HIV infection or cancer, is claimed. Also claimed is a method for diagnosing a dsRNA deficient disease state comprising assaying a sample from a patient for dsRNA and comparing results with a normal control. More specifically, the dsRNA is mismatched and has formula r1n.r(C11-14(n. The dsRNA deficienc...

The invention relates to a process for the discontinuous burning off of carbon deposited on the heat-resistant exhaust gas filter of an internal combustion engine, particularly a diesel internal combustion engine. At least one metal must be present during this process. The problem of ensuring the combustion of the carbon at the minimum temperature and of achieving a long filter life, is solved in ...

The invention relates to a method for manufacturing laminates from thermoplastic material having a multi-layered wall by co-extrusion, in which the material has admixed to it to form at least one of the layers of the laminate a substance which permits this layer to be identifiable on the laminate by the action of physical and/or chemical agents, as well as to a laminate produced by this method. Th...

A TV receiver having circuitry for precluding objectionable display patterns during channel switching includes a frame store for successively storing frames of video signal being displayed. A controlled switch, responsive to the switching signal and a synchronizing component of the displayed signal provides video signal from the currently selected channel to display circuitry except during channel...

By ensuring that the concentration of dissolved methane (11) and oxygen (13) and ammonium is constant throughout the whole of the fermentor (1), a considerable increase is achieved in both the production capacity of the biomass as well as its uniformity and purity. To this is added a lower production cost, in that the cell density in the fluid can be doubled, and also a reduction in the consumptio...

The invention relates to a weed-killing device, having a skimmer which is configured as an envelope 3 or band connected to an electric voltage source, which envelope or band contains fibrous material and liquid weed preparation containing an ionizing salt solution. The skimmer is drawn perpendicular to its longitudinal direction over the weed 11 to be treated and a current- conducting bar 10 conne...

A collapsible and vertically adjustable foot rest consists of two frame parts 1, 2 which are connected pivotably to each other about an axis X, and of which one part 2 supports a foot plate 3 tiltable about a pivot axis Y. The frame parts 1 and 2 are connected to each other by a connection member 4 which consists of two tubes which can be driven telescopically one within the other and can be locke...

The invention relates to a soft-edged edge frame element for a water bed and method for joining two elements of this type to each other to form a structure made up of two edge frames, which are half-parallelogram-shaped in cross section, and a nonwoven fabric, which connects the edge frames to each other, and which structure, with another matching structure, forms the frame of the water bed, which...

A kinematic system for supporting and actuating the front panel moving backward of a household apparatus, such as a cooker, an oven or a stove (whose supply may be gas, electric or mixed) or even a washing machine, a dish-washer, a drier or other household machine, which comprises at least one pair of rocker levers each having a shorter arm and a longer arm, which extend substantially in the longi...
