Abstract: An RF interferometer (10) is provided comprising a power source (12) connected via first and second directional couplers (16, 30) to a load or device under test (34). The second coupler (30) is connected to a second detector (38) sampling power incident on the load (34). The first coupler (16) is connected to a first detector (18) arranged to detect power arising from vector combinations of source voltage and load-reflected voltage. The first coupler - (16) is also connected to a three position switch (20) disposed to present any one of three reflecting arrangements (44A to 60) to coupled source power. The reflecting arrangements (44A to 60) consist of a short-circuited first waveguide (44A, 46A), an open circuited second waveguide (448, 46B) and a directional coupler (50) having two ports (52, 54) remote from the switch (20) connected together by a third waveguide (56). Operation of the switch (20) furnishes three different vector combinations of source and load-reflected voltage for measurement by the first detector (18). This is equivalent to the result achieved by a six-port reflectometer, but with reduced dependence on the frequency stability of components.

Abstract: The layered body has a parent body made of ceramic material and the coating of a metallic material, the parent body preferably consisting of a highly wear-resistant ceramic material, preferably silicon carbide and the coating of nickel. Hitherto, the combination of the good material properties of ceramic material, in particular of silicone carbide, and the good machinability and processability of metallic materials has been a problem. The invention provides for the coating to have a thickness of about 1-15 mm. Ceramic materials can advantageously be exposed in this way to increased working pressures (for example, around 20 bar) with longer service lives. The coating expediently consists of nickel because in this case it is possible to resort to a known technique. Furthermore, the coating may take place only in a subregion of the parent body. For example, the layered body can be constructed as a pump rotor (10), the coating (12) in the region of the rotor mounting being used to receive the threaded bore (11). The external coating of pump housings is also envisaged. <IMAGE>

Abstract: An immunoassay process for quantitative analysis of an analyte antigen (or analyte antibody) in an aqueous liquid sample containing an unknown quantity of the analyte antigen (or analyte antibody). In the first step, the analyte antigen (or analyte antibody) is allowed to react with an antibody (or antigen) in competive with a known quantity of a labelled antigen (or labelled antibody) labelled with a marker in an aqueous solution, the antibody (or antigen) being carried by water-insoluble microparticles in the immobilized state. In the second step, the reaction mixture after the completion of the competive antigen-antibody reaction is spotted on a top porous layer of an integral multi-layered analysis element which includes, in addition to the top porous layer, an intermediate detection or coloring reagent layer and a bottom water-impermeable and transparent support. The top porous layer permeates aqueous solution and has pores sufficiently small to trap all of the microparticles on which carried in the immobilized state are the antibodies (or antigens) bound to the analyte antigen (or analyte antibody) and bound to the labelled antigen (or labelled antibody). Thus, the free labelled antigen unbound to the immobilized antibody (or immobilized antigen) is allowed to pass through the top porous layer to migrate to the detection or coloring reagent layer. In the third step, the   quantity of the marker labelling to the labelled antigen (or labelled antibody) which has not been bound to the immobilized antibody (immobilized antigen) and has migrated to the detection or coloring reagent layer is determined by optical measurement means.

Abstract: An airfoil-shaped body (30) has a relatively thin trailing edge with a series of alternating, adjoining, downstream extending troughs (32) and ridges (34) in its suction surface (36) which form wave-like surface undula­tions terminating at the trailing edge. The ridges (34) in the suction surface (36) form corresponding troughs (38) in the pressure surface (42) near the trailing edge; and the troughs (32) in the suction surface (36) form corres­ponding ridges (40)near the trailing edge of the pressure surface (42). The resulting airfoil-shaped body (30) has a trailing edge with a wave-like shape. The trough and ridge construction delays or prevents two-dimensional boundary layer separation without creating an undesirable drag penalty.

Abstract: A hot-water tank or boiler is described, with an insertion opening on the underside for an internally arranged heating element and with connections for cold water supply and hot water outlet, the hot-water tank consisting of a cylindrical container in the manner of a small tank or of at least two compression-proof cylindrical containers, arranged next to one another in the vertical direction, in the manner of a flat tank, which are interconnected via upper and lower pipe connections. In such hot-water tanks, there is the problem of achieving a better degree of efficiency and greater operational reliability and of being able to manufacture the hot-water tank inexpensively in a constructionally simple manner, the intention being moreover to produce in particular flat tanks which can be extended as required in a simple manner as far as the container content is concerned. To this end it is envisaged that the cylindrical containers consist, in the manner of a modular system which can be extended as required, of assemblable single parts made of plastic with subsequent adhesive bonding, in which connection, in the manner of a small tank, either dome-shaped cover pieces are themselves assembled or dome-shaped cover pieces are attached, overlapping, to a tubular central piece, an insertion opening, which narrows conically outwards, for the heating element being designed in each case on a lower cover piece, or, for two-pipe or three-pipe compression-proof flat tanks or hanging tanks, cylindrical containers are arranged next to one another with pipe connections of the adjacent containers in each case at the vertex of the cover pieces in highest and lowest position. As a result, single-pipe compression-proof hot-water tanks or multi-pipe compression-proof flat tanks or hanging tanks are produced in a constructionally simple manner, which, as far as the container content is concerned, can be extended as required by different assembly or arrangement next to one another, and which in association with the construction make possible the circulation of the water particularly satisfactorily, as a result of which greater operational reliability and a better degree of efficiency are achieved overall. <IMAGE>
