    摘要: In an arrangement for generating electrical signals by means of two magnetic field-dependent resistors (i.e., field plates) each comprised of a semiconductor compound and each arranged on a ferromagnetic extension fastened on the same pole of a permanent magnet, a particularly configured control element comprised of magnetically soft material is provided for varying the resistance values of the resistors through flux displacement. More particularly, the control element is shaped in the form of a spiral and is arranged on a nonmagnetic rotatable control cam in such a manner that, when the control cam rotates, a part of the spiral control element permeated by the flux of the magnet shifts from the one field plate to the other field plate. Such rotation thus changes the resistance values of the plates, thereby providing a change of the output signal of the arrangement.

    摘要: According to the invention, the fuel is supplied to the reformed-gas generator in an amount at least approximately proportional to the instantaneous demand of the internal-combustion engine and is mixed there, in atomized or evaporated form, with so much air and/or fed-back exhaust gas drawn in through the reformed-gas generator that for the air component of the mixture, the air number for the reaction of the fuel in the converter is at least 0.05 but not more than 0.5 and the exhaust gas component does not fall below the exhaust gas quantity equivalent to the air number 0.05 and does not exceed the exhaust gas quantity equivalent to the air number 0.5. The fuel gas mixture produced in this manner, prior to being fed to the combustion chambers of the internal-combustion engine, is mixed with enough additional air sucked in by the internal-combustion engine such that the air number for the combustion in these combustion chambers is at least equal to 1.

    摘要: A magnetic suspension bearing for a rotating body having at least two magnet systems of coaxial permanent magnets arranged sequentially along the axis of rotation of the rotating body. Each magnet system is provided with two permanent magnets disposed on the rotating body and a stator, respectively. Each such permanent magnet is magnetized in a direction perpendicular to a major external surface, the adjacent surfaces of the magnets within a magnet system being of like polarity so as to repel one another. Each of the magnets is constructed so as to form a truncated cone, the axis of which coincides with an axis of rotation of the rotating body. In one embodiment, the apex of the cones are directed towards one another. The apex angle of the cones is advantageously preselected to provide desired axial and orthogonal components of force.

    摘要: The invention is a flow meter comprising a magnetic field-dependent resistor arrangement whose resistances are controlled by a particularly configured control member. More specifically, the position of the control member controls the degree of flux passing from the permanent magnet of the resistor arrangement through the two magnetic field dependent resistors of the arrangement. The resistance values of the resistors thus vary as a function of the position of a control member. According to the invention, the control member comprises a throttle plate having one end clamped elastically to the flow chamber of the meter and the other end within and free to move with the medium flowing in the chamber.In this manner, by varying the pressure head of the flowing medium, the amplitude of motion of the throttle plate, and, hence, the resistance values controlled thereby are varied. A sensitive flow meter having a simple construction is thus realized.
