Abstract: A circuit arrangement for reducing the decay and build-up transient times of an intermittently operating oscillating circuit increases the data transmission rate of a transmission unit using such an oscillating circuit. A control unit is connected to the oscillating circuit including a capacitor, a coil, and a resistor. A switch element controlled by the control unit selectively connects a voltage source to the capacitor, or selectively connects a current source to the coil. In the former case, another switch element selectively disconnects the capacitor from the coil and the resistor. In this circuit arrangement the current and/or the voltage are maintained when the excitation voltage for the oscillating circuit is interrupted. This eliminates the decay of the oscillating circuit amplitudes. When the excitation voltage is switched on again, the oscillating circuit continues oscillating without delay.

Abstract: A process for reducing the decay and build-up transient times of an intermittently operating oscillating circuit increases the data transmission rate of a transmission unit using such an oscillating circuit. In this process, the current and/or the voltage are held at their maximum values when the excitation voltage for the oscillating circuit is interrupted. This eliminates the decay of the oscillating circuit amplitudes. When the excitation voltage is switched on again, the oscillating circuit continues oscillating at its maximum amplitude without delay. The data transmission rate is increased because the decay or starting times are eliminated.

Abstract: Integrated circuit layout for LF signal acquisition in the case of contactless data transmission Known circuit layouts for LF signal acquisition only provide for a very short communication distance between transponder and base unit, and consist of several ICs that need to be assembled. Using bipolar or MOS circuit layouts where the LF signal acquisition for the AM demodulator is effected on at least one of the two H bridge circuit branches. This increases system sensitivity and thus the communication distance between transponder and base unit. Due to the reduced voltage strength requirements with regard to the AM demodulator, it will become easy to integrate this circuit component jointly with the H bridge into an IC.

Abstract: In the previously known processes, the oscillating circuit amplitude decays exponentially after the excitation voltage has been interrupted. Upon switching the excitation voltage on again, the oscillation first has to be built up. This reduces the data transmission rate of transmission plants which are operated by intermittently working oscillating circuits.

Abstract: The invention relates to a charging method for storage batteries, in particular for NiCd and NiMH cells. According to the invention, the rise in the charging voltage during each of a number of consecutive charging cycles of a specified duration is measured in the form of a unit corresponding to a certain voltage. The number of these units is transmitted in the form of a counting pulse to two up-down counters during the period of the charging cycle, whereby one counter functions in the down mode and is set at the beginning of a charging cycle to a number corresponding to the number of units established in the preceding charging cycle. In the following charging cycle, the roles of the two counters are reversed, so that the up-counter is now set to the down mode and the other counter to the up mode, whereby the latter is set to a Certain starting counting status.

Abstract: A charging method for storage batteries, in particular for NiCd and NiH cells. In accordance with the invention, the charging operation is cyclically interrupted for the purpose of measuring the charging voltage. During these measurement intervals, the charging voltage is cyclically compared with a reference value. If the value of the actual charging voltage is greater than this reference value, the latter is increased by a certain amount to match it to the actual value of the charging voltage and then stored. By contrast, the number of measurement cycles is counted in which the value of the measured charging voltage is consecutively equal to or less than the maximum stored reference value. Finally, the charging current source is switched off or the charging current is reduced at a preset counter reading. As a result, maximum utilization of the available effective capacity together with extensive protection against overcharging is achieved.

Abstract: A windshield wiper assembly in addition to carrying the wiper blade, also carries an additional cleaning device which may be a brush, an ice scraper, or an additional blade through which washer fluid may be sprayed. The additional device is coupled with the wiper arm-and-blade assembly by means of a coupling which may be operated by an adjusting element. The additional part is only used, when it is really necessary and, in addition, serves to reduce pressure on the wiper arm-and-blade assembly in the parking position.

Abstract: A cooking station for gas ranges whose burner works with super-stoichiometric combustion air premixing. The burner head arranged in a burner tray is connected with a mixing pipe via a ceramic insulating ring. Between the burner head bottom and the burner head lid with the flat topside, we have two perforated flame opening rings which are arranged concentrically with respect to the burner axis, which are resistant to heat and which are resistant to oxidizing and reducing atmospheres. The perforation of the inner flame-opening ring is so dimensioned that the flames cannot backfire. Below the burner tray there is arranged a reflector. The cooking station can be covered with a glass ceramics plate. The invention achieves stable flame performance, perfect combustion, and waste gas poor in harmful substances at nominal load and at small adjustment heat load within a vast utilization field of gases with differing Wobbe indexes as well as a start-up cooking efficiency improvement compared to known burners.

Abstract: Windshield wiper assemblies include apparatus to compensate for lifting forces exerted on a wiper arm and blade when a vehicle travels at high speeds. The wiper assemblies include a wiper arm spring connected to a wiper rod which carries the wiper blade. One end of the spring is connected to a pin mounted on a lever. The lever is pivotally movable so that the spring force on the wiper rod may be increased to compensate for lifting forces.

Abstract: A wiper assembly for cleaning the rear window of an automotive vehicle includes a closed housing in which the electromotor and the transmission for the swinging drive of the wiper shaft are located. The wiper shaft projects from a self-supporting housing portion at a predetermined distance from the fastening means. The unit can be mounted outside of the body of an automotive vehicle in a way that the wiper shaft points to the window to be cleaned and thereby a wiping angle of 180.degree. can be attained.

Abstract: A device for indicating the loading of a seat, particularly an automobile passenger seat, comprises a seat having a spring suspension with a pull switch mounted on a rigid plate held to the underside of the suspension. The pull switch includes an actuating member which is biased in a first switch position by a resilient element which is secured to a laterally remote part of the spring suspension and it operates on the actuating element to move it to a second switch position when the seat is loaded and the switch is moved with the spring suspension as it is flexed on the load.
