Title: Circuit arrangement for frequency adjustment of a DC voltage intermediate-circuit converter with a constant output voltage
Inventor: NIESEL NORBERT ING GRAD
IPC: H02M5/45
Filed: 1985-07-31
Abstract: In the case of a circuit arrangement for frequency adjustment in the field-weakening range of a three-phase machine (5) which is supplied via a DC voltage intermediate-circuit converter, it is intended to achieve the effect that the three-phase machine always maintains its rotation speed, that is to say even when the amplitude of the output voltage is reduced as a result of mains-voltage reductions. Provided for this purpose is a field-weakening controller (21) to which the control deviation of a control variable (xUD) (which is proportional to the intermediate-circuit voltage) is provided in advance from a reference variable which is emitted by an additional required-value transmitter (14) and is proportional to the magnitude of the mains voltage (UMAINS), and whose output signal is added to the control variable (xUD) (which is proportional to the intermediate-circuit voltage) as an additional variable. The control variable (xUD) (which is proportional to the intermediate-circuit voltage), together with the additional variable, is used on the one hand as a control variable for a frequency controller (13) for which a reference variable (WUD) (which is proportional to the motor rotation speed) is provided in advance and whose output signal controls the mains converter (1) of the DC voltage intermediate-circuit converter, via a subordinate current regulator. On the other hand, the sum of the control variable (xUD) (which is proportional to the intermediate-circuit voltage) and the output signal of the field-weakening controller (21) is supplied to a voltage/frequency converter (25) whose output signal defines the frequency of the machine converter (4) of the DC voltage intermediate-circuit converter. <IMAGE>

Title: Clockwork mechanism for clocks with a striking mechanism
Inventor: KIENZLER AUGUST
IPC: G04B21/10
Filed: 1986-07-15
Abstract: A clockwork mechanism for clocks has a wheel-work mechanism and striking mechanism which are arranged between two bottom plates. The striking mechanism is triggered via a release device which is in operative connection via an intermediate element with a control element coupled to the wheel-work mechanism. A switching element is provided which has a coupling part which lies in the path of movement of the control element in order to cancel the interruption to striking of the striking mechanism. The switching element has a second coupling part which lies in the path of movement of the intermediate element in order to switch off the striking mechanism. In order to move either the control element or the intermediate element out of its respective normal operating position, only the switching element needs to be actuated. As a result, the existing interruption to striking at night can be cancelled in a simple manner and in the day an interruption to striking is made possible by stopping the striking mechanism.

Title: Supply circuit arrangement for lighting means in road traffic signal transmitters
Inventor: ZELLER RICHARD
IPC: G08G1/097
Filed: 1986-10-24
Abstract: A supply circuit arrangement for road traffic signal transmitters, whose lighting means, such as low-voltage indicator lamps, must be matched via additional switching means, such as transformers or converters, to the output voltage of the road traffic signalling system controllers. In order to prevent effects which endanger those in the traffic resulting from a no-load current (caused by the switching means for voltage matching in the event of the lighting means being interrupted) in the signal transmitter circuit on the signal protection devices, a supply circuit arrangement is provided having passive components, such as diodes. In this case, the lighting means is connected via an arrangement of diodes, on the one hand, in a parallel circuit to the output side of the switching means for voltage matching and, on the other hand, in a series circuit to the input side of the switching means for voltage matching and to the signal transmitter voltage outputs of the road traffic signalling system controller. In the event of an interruption in the lighting means, in addition to the interruption in the circuit on the output side, this also results at the same time in the signal transmitter circuit on the input side being interrupted and, in consequence, a no-load current caused by the switching means for voltage matching being prevented from being able to act in the signal protection devices.
Patent DE-3702236-A1 (DE)
Title: Reflector lamp for the indirect lighting of a room
IPC: F21V7/09
Filed: 1987-01-27
Abstract: An indirect reflector lamp (10) has a halogen metal-vapour high-pressure discharge lamp (12) with an elongate-cylindrical outer bulb, which is arranged inside the housing (16) of the reflector lamp and of a reflector (31) forming its inner lining in such a way that it cannot be seen in the position of use of the reflector lamp. The light-emitting window (24) of the reflector lamp runs horizontally in the position of use. The reflector (31) has the same cross-sectional contour over its entire length. It comprises three sector-shaped regions, of which the first two lie close to the discharge lamp (12) and are oriented such that radiation reflected at them does not impinge again on the bulb of the discharge lamp (12) but, if anything, grazes past the latter. The orientation of the reflecting surfaces of the third sector is arranged such that the angles at which reflected light can emerge with respect to the plane of the emitting window are, at most, 90@. With a reflector lamp (10) of such a design, better utilisation of the luminous flux emitted overall by the discharge lamp (12) for room lighting is possible than in the case of previous reflector lamps. <IMAGE>

Title: Self-locking lock
Inventor: DAVIDOVIC MIODRAG
IPC: E05B17/00
Filed: 1987-06-09
Abstract: In order to forestall the carelessness of an individual person passing through, a self-locking lock, in which the lock bolt and the door catch have an equidirectional fall-in slope, is employed for use in doors, through which several persons usually pass, but which, at a specific time of the day, are to be opened only by means of a key and closed again after they have passed through. The orifice for the lock bolt in the door frame can be alternately closed and opened by means of a movable insert piece. Since now the lock bolt too like the door catch, can engage automatically counter to the force of the individual spring, only a brief actuation of the cylinder lock is necessary in order to open the door. In this operation, the bolt and the catch are simultaneously brought into the lock. When the movable barrier is "SHUT", the bolt remains in the lock and the door catch functions in the customary way.

Title: Waveguide junction
Inventor: HOLPP WOLFGANG DR
IPC: H01P1/10
Filed: 1988-02-16
Abstract: In the case of a waveguide junction having one input waveguide and two output waveguides, the three waveguides are connected to one another by waveguide sections having the electrically effective length (2n + 1) .  lambda H/2 ( lambda H = wavelength in the waveguide at the operating frequency). A switchable short-circuiting switch, by means of which the respective output waveguide can be blocked, is arranged in one of the two output waveguides at a distance of a quarter of one wavelength in the waveguide from the junction. If one output waveguide is blocked, all the power which is fed in via the input waveguide is transferred to the respectively other output waveguide which is matched such that it is reflection-free. The waveguide junction can be produced in a favourable manner using a simple technique of milling from a solid block.
