Inventor: HELLBERG RICHARD
IPC: H03F1/02
Filed: 2002-07-03
Abstract: A composite power amplifier includes a first and a second power amplifier connected to an input signal over an input network and to a load over an output network. The output network includes phase shifting elements for generating different phase shifts from each power amplifier output to the common load. The input network includes means for driving both power amplifiers to produce first output current components having an amplitude that increases linearly with increasing output signal amplitude below a transition point (T.P) and decreases motonically with increasing output signal amplitude above said point, and second output current components having an amplitude that increases linearly with increasing output signal amplitude both below and above the transition point.

Abstract: Vehicle heating unit comprising an air intake connection and an exhaust connection, which connections are communicable with corresponding inlet and outlet ducts through the vehicle bottom. In order to perform, in such a vehicle heater, the disassembly of the heating unit, even after several years of operation and consequently corroded coupling clamps for the exhaust manifold and the air connection pipe, a coupling unit attachable to the vehicle bottom is provided. The coupling unit comprises plug couplings or contact pressure couplings, equipped with gaskets for receiving the connections, and, associated therewith, coupling pipe sections oriented toward the outside. The exhaust manifold and the air intake manifold can be attached in the usual way to these coupling pipe sections. However, these manifolds need no longer be detached for the dismounting of the heating device. The coupling unit can be mounted within or externally of the vehicle.

Abstract: A method for nitriding materials using a glow discharge in an atmosphere of nitrogen or gas mixture at a pressure between 1 . . . 100 mtorr (0.13 . . . 13.3 Pa). Nitriding treatment can be combined with a plasma aided coating process and the temperature control during both processes can be achieved with the aid of separate filament. Nitriding unit can be a separate rig or a part of the coating unit. The method can be used to increase the wear resistance of a work piece by increasing the hardness of its surface. Because of the low pressure used in the nitriding process the same equipment can be used to produce a separate hard and wear resistant compound or alloy coating on the nitrided surface to further increase the hardness of the uppermost surface. The main field of the method is in increasing the wear and corrosion resistance of machine parts and tools.

Abstract: A holder 1, for a rear view mirror 10, comprises a housing 5 accommodating a pivot shaft provided with a coupling pin 22 which is loaded by a pressure spring 25 and side engages in grooves in a base piece 23 which can be rotated by an electric motor 3 (Fig. 1) through a worm 13 and wheel 17. When the rear view mirror or the like 10 collides with an object, the coupling part or pin 22 is lifted out of the grooves 24 against the pressure of the spring 25 and when the impact of the collision has subsided, the coupling part or pin 22 will slide down into the nearest groove 24. The motor 3 is then brought into operation, by a push button control, in one or the other of two directions until the mirror has returned to its original position. The motor 3 may also be used for readjustment of the mirror. <IMAGE>

This signal together with the actual force signal, is connected to a further comparison circuit (8) in order to provide a control signal which activates the feed and evacuation of lifting gas. In the gas volume is fitted a second pressure gauge to emit a secondary pressure signal. The pressure together with the force signals, are inputted to a weighing circuit to produce a weighed signal of variable dimension or on the one hand the force signals, and on the other hand a linear combination of the two pressure signals. The weighed signal and that for theoretical force are coupled to the input of the second comparison circuit. (Provisional basic advised week 86/31)

Abstract: Protective coatings are applied to substrate metals by coating the metal surface, e.g. by dipping the substrate metal (10) in a molten alloy of the coating metals, and then exposing the coating at an elevated temperature to an atmosphere containing a reactive gaseous species which forms an oxide, a nitride, a carbide, a boride or a silicide (13). The coating material is a mixture of the metals M1 and M2 of which M1 forms a stable oxide, nitride, carbide, boride or silicide (13) under the prevailing conditions and of which M2 (12) does not form a stable oxide, nitride, carbide, a boride or silicide. M2 (12) serves to bond the oxide, etc. of M1 (13) to the substrate metal (10). Mixtures of M1 and/or M2 metals may be employed. This method is much easier to carry out than prior methods.

Abstract: A method and apparatus for optimizing resource allocations is disclosed which proceeds in the interior of the solution space polytope instead of on the surface (as does the simplex method), and instead of exterior to the polytope (as does the ellipsoid method). Each successive approximation of the solution point, and the polytope, are normalized such that the solution point is at the center of the normalized polytope. The objective function is then projected into the normalized space and the next step is taken in the interior of the polytope, in the direction of steepest-descent of the objective function gradient and of such a magnitude as to remain within the interior of the polytope. The process is repeated until the optimum solution is closely approximated. The optimization method is sufficiently fast to be useful in real time control systems requiring more or less continual allocation optimization in a changing environment, and in allocation systems heretofore too large for practical implementation by linear programming methods.

Abstract: A magnetoelastic force transducer which is compensated for sensitivity drift is provided with a measuring transducer and a reference transducer (1) of the same material. In its simplest form the reference transducer may consist of a toroid. The two transducers are arranged in good thermal contact with one another. The reference transducer is arranged with a winding (2) for excitation with a current which at each moment is proportional to the supply current of the measuring transducer, and with a winding (3) for delivering a reference signal (Ur) proportional to its magnetic flux. The output signal of the reference transducer is rectified in a phase-sensitive rectifier, the output signal of which is compared with a constant reference voltage. The deviation controls the phase position of the control voltage of the rectifier in such a way that the output signal of the rectifier is caused to correspond to the reference voltage. The output signal of the measuring transducer is rectrified in a phase-sensitive rectifier, which is controlled by said control voltage and the output signal of which constitutes the temperature-compensated measured signal.

Abstract: An apparatus for displacing material includes a transport thread composed of a central thread spiral and an outer thread. The outer thread spiral is fixed to one of the radially directed defining surfaces of the central thread spiral. The central thread spiral is dimensioned so as, without permanent deformation, to absorb at least the major portion of the mechanical forces occurring in the axial and radial direction of the transport thread. The outer thread spiral has an outer surface which faces away from the geometric centre axis of the transport thread and is of shorter extent in the axial direction of the transport thread and is located more distally from the center axis than the outer surface of the central thread spiral. By regulating the extent in the axial direction of the transport thread of the surface of the outer thread spiral turned to face the substrate, the abutment pressure of the transport thread will be adapted to the substrate in relation to the properties of the material being displaced.
