Abstract: In an externally controlled electronic ballast, a driving circuit which requires a dedicated supply voltage is provided for the purpose of driving an inventor half bridge. The driving circuit is constructed such that the inventor half bridge blocks when the supply voltage V.sub.cc falls below a threshold value UVLO. Via a self-holding controllable electronic switch and a Z diode DZ2, a voltage monitoring circuit draws the supply voltage V.sub.cc below the threshold value UVLO when an excessively high lamp voltage is detected. The ballast is thereby inactive. A current sensing path which leads via at least one filament of the low-pressure gas discharge lamp serves to detect a change of lamp. The current sensing path controls a further electronic switch, which is likewise connected to the supply voltage V.sub.cc of the driving circuit and can, when it conducts, draw said voltage further to frame than the first switch.

Abstract: The invention suggests a novel medical use of pure bilobalide or Ginkgo biloba extract with an increased bilobalide content as an anxiolytic or antidepressant.

Abstract: An electronic ballast is provided for the operation of one or more gas discharge lamps. The electronic ballast has at least one inverter half bridge and a driving circuit that prescribes the inverter frequency. In the event of overvoltage across a gas discharge lamp, the driving circuit is brought into a locking state in which it blocks the inverter half bridge. This is performed via a circuit resembling a thyristor, which reduces the supply voltage of the driving circuit below a predetermined value. Provided for the purpose of unlocking and restarting the driving circuit is a detector circuit which detects the insertion of a new gas discharge lamp into its respective holder. This is accomplished by pinpoint detection of a steep pronounced voltage rise at a terminal of a gas discharge lamp which is connected to the intermediate circuit voltage via the filament of the gas discharge lamp.

Abstract: An easily assembled socket, particularly for elongated lamps such as fluorescent lamps for use with, or without associated starters, which can be wired by automatic wiring machinery. A socket housing (2) of insulating material has reception chambers (33, 48) for receiving the blade part (57) of an slit blade insulation piercing (SBIP) connector portion (53) of a contact spring (49). The connector portion (53) extends to a connecting element portion (52) which, in turn, terminates in a contact terminal end portion (51) for engagement with a projecting terminal pin of the electrical device. The contact spring (49) is a unitary element, which can be slipped into the reception chamber (33, 48) via a lateral opening (44). Wire positioning recesses (24, 25, 34, 35) are formed in the housing leading to and from the chambers (33, 48).

Abstract: An electrical clamping terminal arrangement with an IDC contact located in a housing of insulating material is formed, in particular for use in an automatic wiring, in such a way that the housing, on at least one side adjoining the introduction slit of the IDC contact, has a slitlike or groovelike indentation opening toward the introduction side for the conductor. The dimensions of this indentation are chosen such that a free end, located in the vicinity of the IDC contact, of a line contacted in the IDC contact is received in the indentation in a shock-hazard-proof manner.

Abstract: To permit easy connection, and further to provide an electrical connection between a conductor and an electrically conductive device, for example, a base plate of a large fixture, a housing (4) of insulating material which has a contact element therein, and a flat surface (9) adapted to be placed against the device (7), is further formed with a metallic strip (28) electrically connected to the contact element (5). The metallic strip is formed with a bend or crease line (34) separating the strip into a neck portion (31) and a hook portion (36). The neck portion and the hook portion, together with the insulated housing (4), form a lever (48) in which the hook portion, upon insertion thereof through an aperture (45) in the flat surface of the device passes beneath and becomes located under the flat surface, engaging thereagainst and being supported therefrom, to permit at least part of the neck portion (31) to be passed, by lever action, through the aperture (45).
