Title: Electrode for quantitative measurement of dissolved gas concn. - with addn. to electrolyte of ions interfering cpd(s). in gas
Inventor: BOEHM HARALD DR PHIL
IPC: G01N27/30
Filed: 1975-06-21
Abstract: A thin electrolyte-permeable and hydrophilic catalyst layer is applied to a thin hydrophobic and gas-permeable layer with formulated ratio of the electrode structure to the electrode thickness, as in 25 10 738, ions of the interfering cpd(s). contained in the gas being added to the electrolyte. Used in cells for the determn. of SO2, H2S, Cl2, NO or hydrocarbons. Cross-sensitivity of interfering cpds. which would falsify the results, is reduced. For electrolytes contg. SO2 and HCl the current ratio is 1:5 x 10-2. On addn. of NaCl to the electrolyte, this ratio is reduced to 1:1.2 x 10-2 witn 4 wt. % NaCl, 1:8 x 10-3 with 8 wt. % NaCl and 1:6 x 10-3 with 10 wt. % CaCl.
Patent DE-2530631-A1 (DE)
Inventor: LINK KLAUS ING GRAD
IPC: H02M1/40
Filed: 1975-07-09
Abstract: In the case of the circuit arrangement for the regulated DC/DC voltage converter, a clock transmitter (P) predetermines the maximum control range at a constant operating frequency. Said control range is determined from the minimum input voltage and the maximum load. A transformer is provided for potential isolation. Switching means (R3, C2, G3), for example auxiliary converters (HU, D3) are provided which vary the maximum control range continuously as a function of the input voltage (UE). This avoids saturation of the power transformer in the event of a load change. <IMAGE>

Title: Recovery of bromine and platinum and other noble metals - and radioactive isotopes, from the ash of tropical fruits
Inventor: BUMBALEK ALOIS DIPL ING DIPL C
IPC: C22B61/00
Filed: 1977-01-22
Abstract: This is an addn. to 1540212 which described a process for winning Au, Pa, Re, Rh, the lanthanides, and natural radioactive isotopes e.g. U, Th, Ra, for the nuclear-, chemical-, and noble metal- industries, starting from the flesh and/or the peel of tropical fruits. The novelty in the present invention is that bromine and platinum are also recovered, where the flesh and/or peel of tropical fruits, esp. bananas, is crushed, and then roasted at 820-840 degrees C. in an oxidising atmos. without forming carbon, to form a mineral ash which is digested and treated in a conventional manner. In addn. to the winning of metals described in the main patent, Pt and Br can be recovered in an economic way. The recovery of both the Pt and the Br is less trouble and more economic than their winning from minerals, ores etc.
