Granted: 1993-08-17
Abstract: ABSTRACT      An apparatus and a method are disclosed for composing an imposition in terms of an arrangement of printing plates on selected of the image positions on selected units of a printing press to print a given edition, by first assigning each section of this edition to one of the press areas.   Thereafter, each printing unit  is  examined to determine  an utilization value thereof in terms of the placement of the printing plates on the image positions and the relative number of image positions to which printing plates are assigned with respect to the total number of  image positions.   Thereafter,  a lift of the image positions for each of the section and its area, is constructed by examining one printing unit at a time in an order according to the placement of that printing unit in the array and examining its utilization value to determine whether or not to include a particular image position of that printing unit in the list.  As a result,  a list of the image positions is constructed in a sequence corresponding to numerical order of the pages in the section under consideration.   Finally, that list of the image positions  and the corresponding  section and page numbers  is displayed in a suitable fashion to inform a user of how to place the printing plates in the desired arrangement onto the printing

Title: After-firing safety device in a projectile with percussion fuze
Inventor: BREDE UWE
IPC: F42C15/23
Filed: 1988-11-17
Granted: 1993-07-13
Abstract: ABSTRACT OF THE DISCLOSURE:        An after-firing safety device in a projectile with  percussion fuze includes a spiral spring set having at least three springs wound up in series with respectively opposite directions.  The spring set,  maintained under tension by a cage, starts to uncoil as soon as the cage slides off the spiral spring set on account of the acceleration of the projectile during firing.  The time elapsing until a central aperture has been entirely vacated depends on the number of springs, the spring lengh, the spring tension, and the friction characteristic.  The after-firing safety device is equally well suited for spinning projectiles as well as nonspinning projectiles.

Abstract: INVENTOR:  WOLFGANG KLINKEL            INVENTION: APPARATUS FOR FORMING, FILLING AND SEALING            BAG-TYPE PACKAGES     ABSTRACT OF THE DISCLOSURE     The invention relates to an apparatus for forming, filling and sealing bag-type packages.  For certain filling products it is advantageous to "strip" or flatten the bag-type package prior to sealing, i.e. to ensure that the bag is volumetrically displaced.  As a result all bag-type packages are tightly filled despite varying specific weight of the filling product.  This object of the invention is achieved by return conveyance or feed of the bag hose or tube and passage of the latter through a constrictive location.       An advantage of the apparatus resides in the possibility of achieving high production speeds by virtue of small moved masses.

IPC: F02D41/20
Filed: 1989-08-31
Granted: 1992-05-05
Abstract: Abstract of the Disclosure Method and Apparatus for Controlling a Solenoid Operated Fuel Injector A solenoid control circuit provides energy to selected solenoids to control actuation of a control valve of a fuel injector and, hence, the timing and duration of fuel delivered to each cylinder of an internal combustion engine.  The current provided to each solenoid is also controlled to provide a three tier current waveform having a pull-in current level, a hold-in current level, and an intermediate current level.  Energizing the solenoid at the pull-in current level starts movement of the control valve.  After the control valve starts to move, the current level is reduced to the intermediate level, which is lass than the pull-in current level, but great enough to continue movement of the control valve.  Further reduction of the current level to the hold-in level, which is less than either of the other current levels but sufficient to hold the control valve at the moved position.  The solenoid is then de-energized and the control valve returned to its initial position to stop the flow of fuel to the engine.  The foregoing is repeated for each of the other control valves of the fuel injectors to save energy and reduce the heat to be dissipated.
