Abstract:
Solid electrolyte capacitors are produced in such a way that a formed metallic anode body which has pores passing through it is arranged on a working electrode, and a conductive polymer is deposited in the pores of the anode body by electochemical polymerization of a monomer in the liquid phase, in the presence of a conducting salt. The polymer is provided with a contact point.
Abstract:
The invention discloses an apparatus for maximizing the uniformity of distribution of gasification medium in a rotary grid generator. To insure proper input, a distribution head is rotatably mounted within the interior of the rotary grid, and the distribution head is connected by means of elastic input conduits to either openings which are directly connected with the reactor chamber, or to distribution chambers in the individual segments of the rotary grid. Through use of the apparatus, the formation of canals through preferential gas flow in the solid beds of pressure gas generators is eliminated.

Abstract:
The apparatus for burning the contaminated soot particles in the exhaust gases of diesel motors of vehicles comprising in the exhaust gas line a housing with a burner operated with a fuel/air mixture for burning the contaminated particles in the exhaust gas flow. The housing comprises a rotatably supported hollow cylinder through which the exhaust gases flow. The housing and the hollow cylinder bound the combustion space of the burner, wherein the hollow cylinder comprises drive vanes and the exhaust gases of the diesel motor and/or the exhaust gases of the burner act upon the drive vanes and wherein the exhaust gases of the burner heat the hollow cylinder up to the combustion temperature of the soot particles. The arrangement can be also made in such a way, that the exhaust gases and/or the combustion gases of the burner flow through bores into the perforated hollow cylinder and exit through the one open end face of the perforated hollow cylinder.

Abstract:
A method for determining the concentration of sugar in the presence of interfering foreign substances, by means of a test electrode with a membrane placed in front of it, the electrode being contained in an electrocatalytic sugar sensor, whereby the test electrode is set potentiostatically to a reactivation potential and to a test potential and the current flowing during the set test period is evaluated as a test signal. The invention formulates a method such that with varying concentrations of urea a sensitive determination of sugar concentration which is reliable over a long term is achieved. The invention discloses the method which includes the step that after the reactivation potential and prior to the test potential a third potential that is more negative than the test potential is applied to the test electrode. The technique proposed in the invention is particularly appropriate for the determination of the concentration of glucose in body fluids.

Abstract:
The electrochemical determination of the oxygen concentration, particularly in biological matter, is possible by means of an oxygen sensor with a measuring electrode and a counter electrode over long periods of time, even if the sensor is implanted, by taking the following measures; two potentials are cyclically impressed on the measuring electrode, with one potential (measuring potential) in the range -1.4 V.ltoreq..rho.Ag/AgCl.ltoreq.-0.4 V, and the other potential (recovery potential) in the range -0.2 V.ltoreq..rho.Ag/AgCl.ltoreq.+0.2 V; the dwelling time at the measuring potential is small as compared to the duration of the cycle; and the current flowing during the measuring period is evaluated as the measuring signal.

Abstract:
Physiological frequency control of a heart pacemaker having a stimulating electrode is accomplished by providing an oxygen measuring electrode and placing it in the body tissue, loading the oxygen measuring electrode with stimulating pulses in parallel with the stimulating electrode, measuring the potential of the oxygen measuring electrode relative to another electrode between stimulating pulses, and controlling the frequency of the pacemaker as a function of the measured potential.
Abstract:
The rolling mill stand, for example a four-high rolling mill stand, for strip mills, with adjusting devices acting horizontally and/or vertically on the rolls for roll nip regulation is characterized by a dual bearing for the work rolls (1, 2) in respectively two inner and outer mounting members (5, 6), which latter, for attaining the same change in shape over the strip width, are horizontally adjustable by deflecting the rolls (1, 2) in the horizontal direction by adjusting devices (7, 8), as well as by a positional control of the inner and/or outer mounting members (5, 6). With the aid of the horizontal deflection device, a position-controlled horizontal adjustment of the work rolls (1, 2) can be performed for compensating for the horizontal forces and/or for a strip thickness regulation while maintaining the horizontal bending curve (13) of the work rolls required for planeness of the strip (14).
