Title: Apparatus for removing oil contamination on the surface of bodies of water
Inventor: DECKER WOLFGANG
IPC: E02B15/04
Filed: 1993-02-27
Abstract: The essential features of the invention consist in the fact that the top part of a tank is designed as a floating chamber, adjoining which at the bottom is a larger oil-collecting chamber which has flooding valves in the base and an oil-intake opening in a side wall directly beneath the floating chamber. During the suction of the flooded oil-collecting chamber, plunging into the body of water up to the oil-intake opening, via an intake line at the base of the oil-collecting chamber, oil contamination floating on the surface of the water is drawn by the developing suction into the oil-collecting chamber, in the course of which the oil-collecting chamber fills with oil from top to bottom. The advantages achieved with the invention essentially consist in the fact that the tank, preferably having the standardised dimensions of a container, can be easily and quickly transported to any site and can be easily and quickly used and that the apparatus according to the invention has a high suction capacity.

Filed: 1993-03-15
Abstract: Catalyst (I) for oxidn., hydrogenation or hardening of cpds., esp. hydrogenation of oils, fats, fatty acids and/or their derivs., contains at least 2 metal oxides, one of which may be CuO, and has at least 30 (wt.)% catalytic crystallites (II) with size varying between 20 and 300 A. (I) pref. has 50-90, pref. at least 70% (II), which have sizes from 100 to 200 A. (II) are mainly on the surface of (I) and embedded in a solid matrix. (II) consist of CuO and (mix) oxide(s) of Ti, Ni, Co, V, Mo, Fe, Sn, Ag, Cr, Si, Al, Y, Ba, La, Sr, Bi and/or Zn and/or metallic Pt, Pd and/or Re; esp. CuO or an oxide of Ni, Co and/or V and also TiO2, Cr2O3, SiO2, Al2O3 and/or ZnO. 40-100, pref. 80-90% of (II) consist of a chemical reaction prod. of the oxides, esp. of CuAl2O4 and/or Cu2Al2O5 or of CuTiO3. (I) is prepd. by treating a solid with the oxide starting amterials (pref. with a particle size of 30-300, esp. 60-120 microns), mixing and crushing mechanically for 1 s to 60 min., pref. 5-15 min. to particles finer than 10 microns, pref. finer than 4 microns, esp. 0.1-4 microns and partic. to a narrow particle size distribution d50 of 0.1-1 micron. The starting materials are heated, pref. to 30-400 deg.C during crushing, pref. in a reactor with an energy density of 0.5-500, esp. 10-200 kW/l reactor vol. Mixing and/or crushing are carried out in a liq. pref. water. The oxidic catalyst is reduced with H2. ADVANTAGE - The formation of coloured by-prods. during oxidn., hydrogenation and hardening is avoided and high yields are obtd., esp. in hydrogenation. In an example, stoichiometric amts. of CuO and TiO2 were ground for 7 min. to particles finer than 10 microns (spectrum 8-1 microns), using an energy density of 30 kW/l reactor vol. The resultant catalyst consisted mainly of CuTiO3 and also contained Cu2TiO3, Cu4TiO4 and small amts. of mix oxides, esp. CuOTiO2 and Cu2OTiO2. This catalyst (IA) had fine crystallites (70%) with a particle size range of 100-200 A on its surface, embedded in a solid matrix of the reactants. (IA) was used in the hydrogenation of methyl laurate (III) to lauryl alcohol (IV) (and MeOH) at 300 deg.C and 280 bar H2, using 3% (IA) w.r.t. (III). After 60 min., a 90% yield of colourless (IV) was obtd. Apart from MeOH and unreacted (III), only one unidentified by-prod. was formed. If a conventional Cu chromite catalyst was used under the same conditions, the (IV) yield was 85% and 2% by-prod. were formed, whilst the (IV) obtd. was intensely coloured by the formation of coloured Cu salts and required purificn. before use

Title: Measurement appts. for room surface reflectivity characteristic determn.
Inventor: BRAUN UWE PETER DIPL ING
IPC: G01N21/55
Filed: 1994-07-12
Abstract: The appts. (23) includes an artificial light, a mirror (4), a fluorescence collector (3), and a solar cell (11). Beams of artificial light from a reflector position (1,2) strike a selected surface through an opening (7). The light density reflection of the surface will be directed by the mirror into the fluorescence collector. There approximately 15% of the light, according to its colour, is deflected whereas the remainder zigzags between the three mirror frames of the fluorescence plate and is collected at the solar cell on the fourth side. This solar cell acts on an electronic switch and the light reflection becomes electrical energy. This signal is fed into an analogue meter, giving an immediate indication of the reflection percentage.
