Abstract: ABSTRACT     Apparatus, for positioning a Venetian blind ladder cord (or the like) and for guiding the slats of a Venetian blind between individual rungs of a multiple cord cross-rung, is described.  Specifically, this apparatus applies a force to a rung of a non-active cross-rung in a direction opposite to that in which the ladder cord advances and provides an abutment surface that engages with the bottom surface of an interlaced slat in order to support the slat form below.  This, in turn, holds the active cross-rung in a fixed position against the force urging the rung downward and thus advantageously maximizes the opening (target) between the individual rungs of the active cross-rung.  Furthermore, this abut-mint surface resiliently moves in a substantially perpendicular direction transverse to the direction in which the ladder cord advances so as to readily permit an assembled slat to advance, while advantageously reducing the likelihood that a heavy slat load will be dumped.

Abstract: Abstract A control device for hydrostatic power assisted steering, particu-larly for vehicles, comprises a measuring motor (10) and a valve arrangement (14) with an outer rotary slide  (16)  and an inner rotary slide (17). A cardan shaft connects the gear (12) of the measuring motor gear train to rotate with the outer slide (16). The axial length of the gear train (11, 12) is at least approxi-mately equal to the length of the cardan shaft (42). The one head (43) of the cardan shaft (42) is connected by way of a  first coupling (44) to a part of the outer slide (16) adjacent to the gear train (11, 12). For the purpose of increasing the depth (t) of at least part of the control grooves (28,  32,  34,  35),  the cross-sectional projection of the inner slide (17) overlaps the cross-section of this head  (43)  in the region of its  largest diameter (D). This permits the control device to pass larger flow quantities without an excessive rise in the pressure drop.

Abstract: INTEGRATED ELECTRICAL DESIGN SYSTEM WITH AUTOMATIC CONSTRAINT SATISFACTION               ABSTRACT OF THE DISCLOSURE An electrical design system is described which integrates many analysis and synthesis tools in an environment of top-down circuit layout.  The system allows electrical design in numerous technologies, including nNOS, CMOS, bipolar, printed circuit boards and others.  Technologies and analysis or synthesis tools may be added or deleted easily, and different technologies may be employed in a single design.  The system includes a database manager which maintains all information regarding the design of the circuit, and which is accessed by all of the analysis and synthesis tools to enable them to examine and modify the design.          The database itself is structured as a network of electrically connected and geometrically described components.  Each component in the database is considered a node, and connections among components are considered as arcs.  Changes are permitted only to nodes, and constraints are imposed only upon arcs. When components are changed, the effects of the changes are propagated to surrounding components by the arcs. In this manner the database manager insures that the circuit remains properly connected throughout the design process while allowing the propagation of changes up and down the hierarchy.
