Title: Furniture hinge
Inventor: LAUTENSCHLAEGER KARL
IPC: E05D5/02
Filed: 1985-06-19
Abstract: In a furniture hinge, of which the supporting-wall fastening part designed as a supporting arm (10) can be pushed onto a mounting plate (20) premounted on the supporting wall of the furniture body and is held by a fastening screw (26) which is screwed into the mounting plate in the end region located inside the cupboard and which passes through a slot (24) located in the supporting arm (10) and opening out at its end directed into the cupboard, there is provided a catch device which, when the supporting arm (10) is pushed onto the mounting plate (20), secures the supporting arm (10) against an unintentional pull-back when the fastening screw (26) is loosened only slightly, but allows such a pull-back when the fastening screw (26) is unscrewed to a greater extent. The threaded shank (50) of the fastening screw (26) is longer than the threaded bore (48) receiving it and opening out at a distance above the bearing surface of the mounting plate (20) in the hollow interior of the latter, and the free end of the threaded shank (50) is enlarged in diameter relative to the threaded bore (48), in such a way that the fastening screw (26) can be unscrewed from the mounting plate only until the threaded-shank end (66) of enlarged diameter bears against the mouth of the threaded bore (48). <IMAGE>

Title: Driver circuit for a two-phase, permanent-magnet stepping motor
Inventor: KUCHENBECKER MANFRED DR ING
IPC: H02P8/32
Filed: 1985-07-15
Abstract: The invention relates to a driver circuit for a two-phase, permanent-magnet stepping motor whose aim is to make it possible to control coil currents with a high dynamic range. A two-phase, permanent-magnet stepping motor is used which has centre-tapped windings for both phases, which are connected via a resistor in order to set the desired attenuation ratio and whose four winding ends are connected to four push-pull circuits which can be selected by the commutation signals. The two push-pull circuits selected in each case are driven by the commutation signals and the variable voltage control signal such that the polarity of the voltage applied to the corresponding windings is determined by the control voltage and, in consequence, it is made possible to control the current on the phase-winding halves, which are in each case switched on continously, as a function of the control voltage, between a positive and a negative maximum value. In consequence, proportional adjustment of the torque of the motor is also achieved. Adjustment of the voltage over the coils instead of varying the coil current is achieved by the use of rotation e.m.f. for damping oscillations of the system. <IMAGE>

Inventor: SCHMIDT PETER
IPC: E01C9/04
Filed: 1987-03-06
Abstract: Elastic plates for level railroad crossings have rail-adjacent edges which are profiled in their vertical cross sections to provide the required interlock. The plates have a first pair of grooves in the top and the bottom of the plate running parallel to the rail and have a second pair of upper and lower parallel grooves in the top and the bottom of the plate running transverse to the rail. In each pair of grooves, the groove in the top of the plate is laterally offset with respect to a parallel groove in the bottom of the plate, and each pair of grooves forms an expansion and contraction crease therebetween. Pairs of grooves in the top and the bottom of the plate are spaced, so that the distances between individual expansion creases, or between expansion creases formed by groups of creases, are large relative to the distance between the grooves which constitute the expansion creases. The first and second pairs of grooves intersect one another and in order to prevent an aperture or opening from being formed in the plate at the points of intersection, an integral layer of material is provided at each intersection to seal between the upper and lower sides of the plates.
