Patent DE-3148846-A1 (DE)
Inventor: ZAUGG EDMOND
IPC: G01R31/36
Filed: 1981-12-10
Abstract: A process and apparatus for determining the state of discharge of an electric battery by measuring the voltage drop associated with changes in its internal resistance. According to the process, the battery is periodically connected to a reference load for a brief interval during which the voltage at the terminals of the load is measured. The measured analog voltage is converted to a digital signal which is compared to a number of pre-programmed digital levels to determine the state of change of the battery. The apparatus comprises a commutation component controlled by a logic signal, a reference load, a sampler-and-hold circuit, an analog-to-digital converter and a comparator which can be programmed at n levels. The apparatus compares digital signals corresponding to the voltage at the terminals of the reference load with the n programmed levels of the decoder and a signal is generated indicating the level of the electric battery with respect to the levels programmed into the comparator.

Title: Method and device for verifying the display values in digital displays composed of display elements having a plurality of display segments
Inventor: SCHNEIDER ELI-JOSEF ING GRAD
IPC: G09G3/00
Filed: 1981-12-23
Abstract: In a method for verifying the display values of digital displays having one or more display elements each of which has a plurality of display segments, in which method the display values occurring on the display segments of the various display elements are detected and compared with the input values, in order to output an error message in the event of deviations from the desired values, it is provided that the display values are detected on all the segments of the display device consecutively in a prescribed sequence and are compared with the associated input values. In this way, it is possible to use for this method a display device which has monitor units for detecting the display values occurring on the segments of the display elements, as well as comparison devices for comparing the detected values with the input values, as well as an error indicator, and in which display device a control device is provided which consecutively connects a single monitor unit to all the segments of the display elements.

Title: Process for producing a sealing and/or insulating part
Inventor: STOLL WERNER
IPC: B62D25/24
Filed: 1982-02-27
Abstract: In the case of a process for producing a sealing and/or insulating part (16), foam boards (13, 15) are laminated onto a rigid, impregnated paperboard (14), serving as a supporting part. From this arrangement of large surface area, the sealing and/or insulating parts (16) are punched out and subsequently encapsulated in an elastomeric skin (20). If the paperboard (14) and one of the foam boards (13 or 15) is to extend only over part of the surface area of the sealing and/or insulating part (16), the remaining part of the paperboard (14) and of the foam board (13 or 15) lying thereover is likewise punched off and, after splitting the paperboard (14) from the remaining, lower foam board (15 or 13), is drawn off. In order that the lower foam board (13 or 15) is not also punched through during this punching operation, the punching block (10) has at this point a groove (11), into which the punching cutter (18), which can be lowered as far as the punching block plane (12), pushes the foam of the lower foam board (15 or 13), so that severing of the latter is prevented. The sealing and/or insulating part (16) can be used universally; preferably, profiled sealing strips produced by this process are used for sealing off covers in bodywork construction. <IMAGE>

Title: Radio-frequency power amplifier
Inventor: DJAMSHIDPOUR MASSOUD DIPL ING
IPC: H03F3/193
Filed: 1982-05-05
Abstract: An RF power amplifier in push-pull class AB operation is to be specified in which no power preamplifier is needed and the RF to be amplified is supplied directly, that is to say without transformer, to the transistors of the push-pull amplifier stage. This is achieved by the fact that the push-pull control voltages (UHF1, UHF2) for two normally-off power field-effect transistors (T1, T2) are generated by means of an inverting amplifier (V1) and a non-inverting amplifier (V2), the inputs of which are connected in parallel. <IMAGE>

Title: Power controller for a vacuum cleaner, especially a floor vacuum cleaner
Inventor: BRETERNITZ BURKHARD DIPL ING
IPC: A47L9/28
Filed: 1982-11-26
Abstract: The invention relates to a power controller for a vacuum cleaner, especially for a high-power floor vacuum cleaner, which allows the user to set the respectively most favourable suction power for the material which is to be sucked up, by operating a key. The object of the invention is a cost-effective power controller which is easy to operate, is functionally reliable and manages without a specially constructed suction hose and without costly wireless remote-control means. The object is to permit and ensure control of the suction power by means of foot operation such that the vacuum cleaner starts at a preferred power and can be switched back to this power. This is achieved in that the power controller has an electronic speed actuator in whose control loop a plurality of fixed resistors, which can be switched on, are arranged for adjustment of the power, and the fixed resistors are switched on via relays which, for their part, are driven by a preferably electronic ring counter, and the ring counter is switched onwards by a sequence of control pulses which are produced by a foot-operated, large-area key. <IMAGE>
