    摘要： The method for forming rings of uniform thickness from an active brazing alloy by melt-spinning the liquid alloy has the following steps: The alloy is liquefied in a crucible having a lateral opening whose height is approximately equal to the width of the ring material; the liquid alloy is forced out of the crucible onto the side surface of a metal drum of high thermal conductivity at a radial distance from the drum center approximately equal to the ring diameter, said metal drum rotating at a high circumferential velocity at a distance from the crucible approximately equal to the ring thickness; after an,,,approximately quarter to three-quarter turn of the active brazing alloy solidified on the metal drum into ring material, the latter is lifted off the metal drum by a mechanical deflector or a gas stream blown onto it in a direction opposite to the direction of rotation of the metal drum, and guided past the crucible; the ring helix being formed is guided around a lateral, coaxial extension of the metal drum which is located on one side of the crucible, serves as a winding mandrel, and has an end flange and a diameter slightly smaller than the inner diameter of the rings, and from the ring helix, the rings are cut off.

    摘要： This active brazing preferably serves to braze (join) ((aluminum-)oxide-)ceramic parts or single crystals or metal parts or to braze (join) ((aluminum-)oxide-)ceramic parts to single crystals or ((aluminum-)oxide-)ceramic parts or single crystals to metal parts. In addition to the zirconium-nickel alloy, which is composed of 70 atom % to 85 atom % zirconium and 15 atom % to 30 atom % nickel, it contains titanium. In an apparatus for fabricating a foil (6) from this ternary active-brazing alloy by melt spinning which has a uniform thickness and two surfaces that are as smooth as possible, the alloy, after being melted by high-frequency heating in a cylindrical crucible (1) made completely of a high-temperature-resistant and highly thermally conductive nonmetallic material, particularly of high-density graphite or of boron nitride, is forced through an opening (3) in the bottom of the crucible onto a metal drum (5) of high thermal conductivity rotating at a high circumferential speed, on which the liquid alloy solidifies at a cooling rate on the order of 10.sup.3 .degree. to 10.sup.6 .degree. C./s. A product made using this ternary active brazing is a pressure sensor (10 ) having a substrate (12) and a diaphragm (11) of ceramic, particularly alumina ceramic, preferably with a purity of 96 wt. %, which are thermally joined around the periphery in a defined spaced relationship (d) and parallel to each other by means of the active brazing , e.g., by means of a preform (20) made therefrom, thus forming a chamber (13) .
