Inventor: KOENIG THEO DR
IPC: C23C4/12
Filed: 1992-05-04
Abstract: Fine-grain metallic and/or ceramic powders are produced by the gaseous phase reaction (CVR) of metallic cpds. and other reactants, whereby: the metallic cpd(s). and other reactants are introduced into the reactor and react in the gaseous state, with the condition that the metallic cpd(s). and reactants are not introduced unless they are at least at the reaction temp.; the product is homogeneously condensed directly from the gaseous phase, with all side reactions suppressed; and the product is removed from the reaction system. The reactor of choice is a tubular reactor, with coaxial, laminar introduction of metallic cpds. and other reactants to the reactor and laminar flow of the metallic cpds., other reactants and product particles through the reactor. Incoming streams of metallic cpds. and reactants are mixed in a specific way by means of Karman's vortex path, and the walls of the reactor are protected from the reaction system by a layer of inert gas. The metallic or ceramic powders produced are removed from the reactor at temps. above the b.pt. or sublimation pt. of the metallic cpds., reactants and any intermediate products formed during reaction, and purified by alternating evacuation and flooding with gases e.g. N2, Ar and Kr, esp. pref. SF6. Surface modification of the metallic or ceramic powder is achieved by treatment with a gas/steam mixture. ADVANTAGE - Highly pure metallic or ceramic powders are produced with good reproducibility and within a narrow, predetermined size range.

Title: Determining chromium or zirconium content of leather - by measuring X=ray emission and back-scattered intensities, and calibration for the effect of sample density
Inventor: ESCHE HANS-JUERGEN DR ING
IPC: G01N23/22
Filed: 1992-06-04
Abstract: The Cr or Zr content of leather is determined by exciting the characteristic X-rays of the metal and measuring the intensities both of this radiation (Ip) and of backscattered exciting radiation (Ir), the measurement being made on a sample of backscattering saturating thickness. The metal content is calculated using a calibration (done once only) based on samples of known density and known metal content, and from determn. of the dependence of the parallel shift of the curves log Ir vs. metal content on the sample density. USE/ADVANTAGE - The Cr (or Zr) content is an essential criterion for the quality of tanned leather. All Cr-in-leather analyses can now be done for a single calibration. The method is based on the fact that Ip is directly proportional to Cr content while Ir is inversely proportional, so that a plot of Ir vs. Cr content varies only according to sample density.

The deformation heat is supplemented with heat from outside to carry out a follow-up heat treatment of the wire. The appts. includes program controlled roll sets for production of wire with the section modulus varying according to a given pattern along its length. USE/ADVANTAGE - In the mfr. of helical compression springs for the motor industry, for example.
