    • The invention relates to a circuit arrangement for operation of a discharge lamp (EL) with an inverter (INV) which generates a high-frequency alternating current from an input voltage and with a tuned circuit provided with at least one choke (L) and at least one tuned capacitor (C3, C4), by means of which the lamp (EL) is supplied, whereby at least one tuned capacitor (C4) is connected in series with a switch element (T1) parallel to the lamp (EL). The resonance capacitance for control of the lamp can be varied by switching in or out the tuned capacitor. For example, the resonance capacitance can be increased for pre-heating and reduced on lamp operation.

    • The invention relates to a HF surgical instrument for treating, in particular, for cutting and coagulating biological tissue by means of a HF current. The HF surgical instrument comprises a HF generator for supplying a HF current to a cutting electrode and comprises at least one control device for interrupting a HF current circuit. The design of this HF surgical instrument is improved in that a cutting capacity is enhanced. In addition, the control device comprises a current monitoring device that detects the amplitude of the HF current and then generates a first switch-off signal when the HF current decreases over a defined period of time and/or the HF current falls below a threshold value characterizing a state of the treated tissue. The control device also comprises an electric arc monitoring device, which then generates a second switch-off signal when an electric arc occurs between the cutting electrode and the tissue. The control device is designed in such a manner that the HF current circuit is interrupted in response to the first switch-off signal or the second switch-off signal.
    • 本发明涉及一种HF手术器械,用于特别用于通过HF电流切割和凝结生物组织。 HF手术器械包括用于向切割电极提供HF电流的HF发生器,并且包括用于中断HF电流电路的至少一个控制装置。 改进了这种HF手术器械的设计,因为提高了切割能力。 此外,控制装置包括电流监视装置,其检测HF电流的幅度,然后当HF电流在限定的时间段内降低和/或HF电流低于阈值时产生第一关断信号 表征处理组织的状态。 控制装置还包括电弧监视装置,当电切割电极和组织之间发生电弧时,该电弧监测装置产生第二关断信号。 控制装置被设计成使得HF电流电路响应于第一关断信号或第二关断信号中断。

    • The invention concerns an electrosurgical instrument comprising two articulated branches, which can be actuated in the manner of a squeezing tool. The instrument further comprises electrode parts at the distal ends of the branches for grasping tissue and for conducting a coagulating current through the tissue in order to cause it to coagulate as well as current-supplying devices for supplying the coagulating current to the electrode parts from an HF generator. At least one device for preventing a short circuit is arranged and configured on the electrode parts in such a way that the electrode parts are unable to touch.

    • A cat litter box with a pivotable container housed on a frame, the tray floor of which forms a collection tray for cat litter and the like. A cleaning mechanism is arranged standing in the container and reaching to the floor of the tray, with which cleaning mechanism, when the container is pivoted in one direction to clean it, waste matter, particularly feces, can be separated from the cat litter. The container possesses a storage chamber for the separated waste matter which can be moved with the container, which chamber is formed by a bag, the entrance of which chamber is arranged above the cleaning mechanism in the position of use. The tray floor consists in accordance with the invention of a half shell which extends over a span area of less than 250° which with a first part shell section forms the floor of an essentially open collection tray and with the other part shell section forms the rear wall of an interim storage tray for litter, whereby the cleaning mechanism is arranged at the transition segment between the part shell sections, and the storage chamber is arranged in the position of use on the side of the cleaning mechanism facing the interim storage tray and whereby the pivoting of the container from the position of use is restricted to a pivot movement of 120–180° in the one direction.
