Title: Method and control arrangement for controlling the output voltages of two dc supply devices
IPC: H02M3/137
Filed: 1989-09-18
Granted: 1992-08-19
Abstract: The output voltages (Ud1, Ud2) of two D.C. choppers (7, 9, 72, 92) connected in series on the input side are to be controlled. For this purpose, the sum voltage (U SIGMA  = Ud1 + Ud2) and the error voltage (U DELTA  = Ud1 - Ud2) of the output voltages (Ud1, Ud2) of the D.C. choppers are formed as secondary controlled variables. The sum voltage (U SIGMA ) is compared to a desired value of the sum voltage (U SIGMA Soll), and fed to a sum-voltage controller (10). The error voltage (U DELTA ) is compared to a desired value and fed to an error-voltage controller (11). The output signals of the two controllers (10, 11) are added or subtracted from one another and used in this way to form the pulse duty factors (a1, a2 and a11, a12, a21, a22 or a1H, a1T, a2H, a2T) for controlling the D.C. choppers. <IMAGE>

Abstract: A system for controlling x, y and z directional movement of a point adjacent to the free end of an arm composed of a plurality of interconnected articulated arm segments mounted for movement relative to at least three axes and providing for individual, independent control of movement of the point in any selected one of the x, y or z directions by controllably relatively adjusting the relationships between the segments. The system is particularly suitable for use in equipment when the arm incorporates a boom and stick such as backhoes or the like.

Abstract: To reduce the power consumption and cut down the heat generated, the inverters (IV) of the master stage (MA) and slave stage (SL) have in each case drain terminals (D) and source terminals (S) which are isolated from the substrate (SU), the source terminal (S) of the inverter transistor of the one channel type (P) and the source terminal (S) of the inverter transistor of the other channel type (N) in each case being connected in an own stage clock (master clock (CVM) or slave clock (CVS)) to the associated CMOS operating potential source (VDD, VSS) and to each other in phase opposition in a respective stage clock (CVM, CVS). By means of a case capicitance (CP, L), acting between two register stages, given at least approximately random distribution of the digital signal levels "1" and "0", the stage-internal voltage excursion in the master-slave registers is reduced. <IMAGE>

Abstract: A valve has a housing forming a compartment traversed by an axis and having a radially opening outlet port and an axially open inlet port, a valve plate fixed in the housing and formed relative to the flow direction with a flat upstream face and with an axially throughgoing valve orifice opening at the face, and a control plate in the housing formed relative to a flow direction through the valve with a flat downstream face riding on the valve-plate face, an axially throughgoing control orifice opening at the face, and an axially open and radially elongated socket on the face adjacent the respective orifice. The control plate is pivotal on the valve plate about the axis for alignment of the orifices and flow through the valve from the inlet port to the outlet port and for misalignment of the orifices for restricted flow from the inlet port to the outlet port. A valve stem rotatable in the housing about the axis projects through the valve-plate orifice and is formed with a foot projecting radially from the axis, fitting in the socket, and rotationally coupling the stem and the control plate.

Abstract: A blank book attachment having a mark and sweep leaf with a fold out feature is provided. The leaf is pivotably retained along one edge on a frame, and the frame is pivotably retained at the binding spine of the host blank book. Pulling outward on the leaf causes the leaf to extend out and beyond the pages of the book allowing the pages to turn freely. When the leaf is placed within the host book, with the book open or closed, the leaf can be turned as a page, in which case it also acts as a mark to identify a specific position in the host book. Alternatively, the leaf may be pivoted on the frame to allow the host book pages to be turned past it in either direction.

Le corps unitaire (24) possède une partie supérieure concave vers le haut (24) s'ouvrant sur la charge propulsive (13) et une partie de base généralement cylindrique (30). La partie supérieure (28) peut subir une déflexion. Ces parties (28, 30) et la paroi tubulaire (14) définissent entre elles une cavité annulaire (42) à l'arrière de la charge propulsive (13). Cette cavité (42) est déformée et s'affaisse lors de l'allumage de la charge propulsive (13) par déflexion de la partie supérieure (28), ce qui réduit le recul ressenti par le tireur, sans pour autant ajouter un poids parasite à la charge du projectile. La partie supérieure (28) de la bourre de base (12) présente de préférence une forme en cône creux tronqué et inversé. Un canal annulaire ouvert vers le haut (52) dans la surface extrême supérieure (36) de la portion de base (30) de la bourre de base (12) augmente la force d'étanchéité entre la partie de base (30) de la bourre (12) et la paroi tubulaire (14) de la douille (10) de la cartouche.

The process provides a quick plant-efficient process for the production of stable dilute lower aliphatic peracid solutions for industrial disinfection purposes or for personal or domestic hygiene use.
