Patent EP-0392046-A1 (EP)
Inventor: MALKMUS HANS DR
IPC: E06B11/04
Filed: 1989-04-12
Abstract: A gate with a gate member which can be slid into a closed or open position, in particular a side sliding gate, is provided on the front and rear of the gate member with a respective lighting strip. The lighting strip has a serial arrangement of electric lamps which are held in an enclosure by a cover plate. The individual lamps or small groups of adjacent lamps are connected to switches, which connect the lamps to the voltage source, or separate them therefrom, as a function of the direction of movement of the gate member upon reaching or leaving the gate opening which can be closed by the door member. As a result of the design, a lighting strip which lengthens or shortens with the movement of the gate member is provided, which draws greater attention to itself and thereby reduces the risk of accidents when the gate is closed or opened.

Abstract: An apparatus for coupling an induction generator to ac power mains comprises semiconductor switching elements for connecting the induction generator to the ac power mains, a firing circuit for providing firing pulses to the semiconductor switching elements and an enabling means which provides an enabling signal to the firing circuit preferably at a predetermined rotational speed of the shaft of the induction generator below the synchronous speed. The firing circuit comprises means for forming a single firing pulse for each semiconductor switching element for each half cycle of the mains voltage, wherein the duration of each firing pulse increases from a phase angle of 180° of the corresponding phase voltage to a predetermined smaller phase angle of this phase voltage. Further an adjusting element is provided for setting the predetermined smaller phase angle where each firing pulse starts, and a current detection circuit is provided for comparing the firing pulse duration with the period during which a current flows through the corresponding semiconductor switching element. Said means includes a compensating circuit for increasing the firing pulse duration to half the cycle time of the mains voltage.

Abstract: The microprocessor of the sewing machine can be changed over from a normal operating state for controlling sewing operations to a diagnostic state for controlling diagnostic programs. The diagnostic programs are activated by operating selector switches of the sewing machine which are present in any case, and the diagnostic results are displayed by means of indicator members of the sewing machine which are present in any case. To make the diagnosis easier, there is a mask (10) which can be laid on the operating and indicator zone of the sewing machine and which contains instructions as regards the activation of particular programs and the reading-off of the results. At least in one case, there are means (32, 33, 36) of also entering and storing collecting commands according to the result of the diagnosis. This affords the possibility of simple and versatile diagnosis and even the possibility of intervening in the electronics of the sewing machine.

Abstract: A transducer (26) is directly associated with a fluid-type damper (18) having a cover member (36) and a cylinder member (28) that undergo telescopic movement relative to each other in response to relative movement between vehicle components (12,14) interconnected by the damper (26). In the preferred embodiments, both a passive electrical coil (40) and a magnet (44) are mounted upon the cover member (36), in fixed relationship to each other. Relative axial telescoping movement between the cover member (36) and the cylinder member (28) of the damper (26) changes the flux field of the magnet (44) and induces in the coil (40) a voltage which is proportional to the relative velocity between the damper members (36,28) and thus between the vehicle components (12,14) interconnected by the damper (26). In an alternative embodiment, the magnet (44′c) is mounted upon an end portion of the damper cylinder member (28c).
