Patent DE-4117969-A1 (DE)
Inventor: SCHERTLER ROMAN
IPC: C23C14/56
Filed: 1991-05-31
Abstract: The invention proceeds from a vacuum process apparatus for an article which is processed or treated, resp. at two stations, whereby each station has a charging and/or removing opening for the article. A transporting device is supported for rotation and includes a supporting portion which is successively moved onto the openings of the stations. The process plant is designed in such a manner that the surface normals determined by the surfaces of the openings and the space axis defined by the axis of rotation of the transport device do not run parallel and rather enclose together an angle of 90° or 45°. By such an arrangement it is possible to design extremely compact vacuum vapor deposition apparatuses having a plurality of individual stations, whereby additionally short transporting distances are obtainable and the volumes to be conditioned can be minimized.

Title: Throttle control for vehicle IC engine with two parallel throttle valves - has servo-drive on secondary throttle valve to control idling speed and take=up pedal travel slack
Inventor: SCHNEIDER ERWIN
IPC: B60K26/04
Filed: 1991-08-09
Abstract: The main throttle valve (5) is operated directly from the throttle pedal linkage (3) between min. and max. stops. A coupling to the secondary throttle valve (13) operates with a controlled gearing (12) to cover the increasing throttle settings. An electrically driven servo (17) provides additional control for the throttle i.e. to adjust the torque to regulate the idling speed. The servo drive operates in conjunction with position monitors (6) on the main throttle valve drive, and position monitors (20) on the servo drive. The control operates the servo to take up any slack in the drive linkage and provide a positive throttle control. ADVANTAGE - Engine power control for two throttles using throttle pedal, and motorised idling control.

Patent DE-4204589-A1 (DE)
Inventor: LECHNER KARL
IPC: G01N3/04
Filed: 1992-02-15
Abstract: A material-testing apparatus for applying a compressive or tensile force to a test piece is capable of automatically compensating for undesired bending moments in the test piece. To this end the two specimen holders 6, 7 are each provided with three piezo-electric linear adjusting elements 8 whose direction of movement extends parallel to the testing force direction P. These adjusting elements 8 are arranged at the corners of an equilateral triangle perpendicular to the force direction and a force-sensing device 9 is allocated to each of them. Measurement by the sensors 9 of the individual forces at the corners of the triangle are fed to a controller which in turn controls the adjusting elements 8 until all the sensors exhibit the same compressive or tensile force, whereupon the clamping of the test piece is substantially free of bending stress. The test specimen 3 (e.g. a ceramic material) may be heated during testing by a surrounding heater (15) (Fig 2) which is spaced from the elements 8 and sensors 9 sufficiently to protect them. <IMAGE>

Title: Contactless power and data transmission device - uses vector orientated phase modulation for both one and two coil system operation
Inventor: MACKENTHUN HOLGER
IPC: H02J5/00
Filed: 1992-11-30
Abstract: The device has a fixed micro-station (M4) with an oscillator or externally supplied clock signal for contact free power and data transmission. The device uses a pair of coils (S1, S2) in a moveable micro-unit (M1) with one or two coils. In the micro-station (M4), two synchronous 90 deg. phase-shifted oscillations of the same frequency are produced. These are converted in a phase modulator (P1) in dependence on the data signals (D1) to be transmitted. The oscillations (Q1, Q2) control amplifiers (T1, T2) and transmission coils (S1, S2) to provide magnetic energy fields with phase information. The micro-unit (M1), independent of its spatial location relative to the micro-station (M4), must receive energy and send data. Thus it receives data even while data is being transmitted from it to the micro-station. Reception takes place independently of the electric load on the circuit so amplitude variations due to path changes or temperature, etc., have no effect on the signal transmission. USE/ADVANTAGE - Contactless chip-cards, electronic keys and other data carriers. Allows power and data transmission from read/write station to e.g. chip card using same method for different cards with either one coil, one big coil or two small coils.
Patent DE-4241362-A1 (DE)
Inventor: BARTELS STEFAN DR
IPC: H04B1/10
Filed: 1992-12-09
Abstract: In a broadcast receiver with an input circuit to which receive signals can be fed, with a mixer to extract an IF signal and with an IF filter whose passband corresponds to a useful frequency range of the receive signal, the receive signals are amplitude-modulated with an auxiliary signal in order to identify intermodulation, sidebands lying outside the useful frequency range occurring therein. The amplitudes of at least one sideband produced by the modulation with the auxiliary signal and of the received carrier are compared in the IF signal. In the event of variances in a relationship determined by the modulation factor in the modulation with the auxiliary signal, a signal indicating the presence of intermodulation is extracted. <IMAGE>
