Title: Lockable rotary handle operator for circuit breaker
Inventor: GRUNERT KURT ALBERT
IPC: H01H73/02
Filed: 1992-07-10
Granted: 2004-04-20
Abstract: A rotary handle operator for a circuit breaker with a linearly movable handle has a housing which is mounted over the circuit breaker handle. A slide carrying a rack engages the circuit breaker handle and is slidable within a chamber in the housing. The rack engages a pinion gear sector mounted on a rotatable shaft which extends through a cover on the housing. A rotating handle mounted on the shaft is rotated to linearly operate the circuit breaker handle or is positioned thereby when the circuit breaker trips. The handle may be locked in the off position by inserting the shackle of a lock through an aperture in a lever arm on the rotating handle to urge a pin on a spring biased locking piece within the handle lever into an aperture in the housing cover, or the shackles of several locks may engage a slot in a shroud surrounding the rotating handle to interfere with rotation of the handle out of the off position. An interlock for the door of a cabinet in which then circuit breaker may be mounted is incorporated into the rotary door operator.

Granted: 1997-09-16
Abstract: A method and apparatus of the alternately displaying two separate data entry views of an electronic mail object. A  first  data  entry  view  graphically  displays  a  visual metaphor  of  at  least one  sheet  of  note paper partially overlying an envelope, with only a portion of the envelope visible  in the  display.   A  second  data  entry  view graphically  displays  a  visual  metaphor  of  an  envelope overlying a portion of at least one sheet of note paper, with only a portion of the sheet of note paper visible in the display.  In either view, the overlying displayed sheet of note paper or envelope is active for the entry of message text or destination  information,  respectively,  while  the partially displayed  envelope  or  sheet  of note  paper  is inactive to such data entry.  Instead, the selection with a pointing device of the partially obscured envelope or sheet of note paper causes that selected envelope or sheet of note paper to be fully displayed and rendered active for data entry while rendering inactive and partially obscuring the previously active field.

Granted: 1997-01-14
Abstract: The invention is an improvement in a gear assembly having a gear segment attached to a spider.  The improvement comprises a pair of spaced spider webs and a segment-attached mounting member received between the webs.  The mounting member has a pair of spaced plates, one plate against each web.  Each of a group of tube-like generally cylindrical segment coupling members extends between a particular web and its adjacent plate while each of another group of coupling members extends between the other web and its adjacent plate.  The coupling members of a group are in opposed relationship to corresponding coupling members of another group.  A bolt-like retaining member extends through each pair of opposed coupling members (with clearance therebetween) and prevents such members "working" out of position.

Filed: 1991-03-25
Granted: 2000-06-20
Abstract: A method for automatically placing objects on a surface in proximity to corresponding predetermined locations without collision with such locations or other objects by defining a distance dependent attractive force between each object and the corresponding location which increases with increasing distance between the object and the location, and defining distance dependent repulsive force between each object and its neighboring objects and locations, such repulsive force decreasing with increasing distance. The initial position for each object is established in proximity with the corresponding location in accordance with predetermined criteria.      Thereafter the motion of the objects under the influence of such forces and of a frictional retarding force are determined by marginally stable incremental integration of such motion. The objects are statically placed at a predetermined target distance from the corresponding location at the position around the location at which the sum of the absolute values of the magnitudes of the forces acting on the object is at a minimum.
