Granted: 1994-07-12
Abstract: A b s t r a c t : (in conjunction with fig. 1) 1. Foil pack for paper tissues.   2.1.   Packs  for  stacks  of  folded paper tissues (10) are made of very thin plastic foil or film.  For  easier  usage, these  packs  have lately been provided with tear-open aids, especially in the  region of  a  front  wall  (11) of  the cuboidal  pack.  In  order  to  open and reclose the pack, a tear-open flap (22) is defined  by  perforation  lines  (23, 24, 25)  in  the region of the front wall (11), which can be opened and reclosed with the  aid  of  a  covering  adhesive flap (37).   2.2.   In  order  to increase the function value of the foil pack, the tear-open flap (22) limited by  side  perforations (23, 24)  is  narrower  than the front wall (11), especially such that a recess (32) of sufficient size for extracting  a paper  tissue  (10)  is formed. Adjoined to the perforations of the tear-open flap (22) is a transverse perforation  (28, 29)  in  the region of a front edge (26), which is opened by way of lifting the end wall of the pack.  Herewith,  an  ex-trartion  opening  (21)  extending across the whole width is formed.   2.3.   With this embodiment of the tear-open aid  it  is  of advantage  to design the pack such that folding flaps of the end wall 16 are separated by means of  punch  cuts  (43, 44) and can thus be folded in rectangular shape.

IPC: H03C3/06
Filed: 1990-07-17
Granted: 1999-07-13
Abstract: A frequency modulator is formed in a monolithic integrated circuit as a whole.  A direct current signal from a center frequency control circuit and an alternating current signal from a voltage controlled amplifier (VCA) which receives a modulation signal and outputs the alternating current signal are applied to a control input of a voltage controlled oscillator (VCO).          A center frequency (Fo) of the VCO is determined by the direct current signal from the center frequency control circuit and a frequency deviation amount (.DELTA. f) of the VCO is determined by the alternating current signal from the VCA, and therefore, a frequency-modulated signal of Fo +          .DELTA. f can be outputted from the VCO.  The direct current signal from the center frequency control circuit is also applied to a control input of the VCA, and therefore, the center frequency of the VCO as well as an amplitude of the alternating current signal, that is, the frequency deviation amount can be controlled by only the direct current signal.

Granted: 1995-04-11
Abstract: An  inter-panel  process  flow  control  method  and system for enabling an uninhibited change of scope from the active panel to another panel visible on a display screen.    The   process   relies   on   object-oriented programming  constructs,  particularly  the  inheritance property,  and the control methods associated with the panel class.  A hierarchical internal program logic is implemented wherein each child panel inherits the control method of its parent panel.   An Action Router control method determines if a change of scope request can be handled locally by the currently active panel.  The child panels of the currently active panel are queried in a controlled sequence using this inherited control method until a child panel is found that can handle the change of scope request.

Title: Microcomputer based electronic trip system for circuit breakers
Inventor: DURIVAGE LEON WILLIAM III
IPC: H02H3/33
Filed: 1990-08-24
Granted: 1999-07-20
Abstract: A processor-based tripping system uses a precise three phase current detection circuit using a minimal number of components. A set of current sensors is situated adjacent the current path to sense respective phases of current therein. The current sensors provide respective current signals therefrom which are fed to a ground fault transformer. The ground fault transformer includes input inductors connected to respective ones of the current sensors such that current flowing through each respective current sensor also flows through one of the input inductors. An output inductor in the ground fault transformer is coupled with the input inductors for adding the current signals from the current sensors and for producing an output current signal in the presence of a ground fault. The output current signal is then rectified to provide a rectified signal corresponding to the output current. The processor receives the rectified signal to detect the ground fault in the three phase current path and provides a trip signal to a solenoid to break the current path. The ground fault transformer also includes a test input inductor for receiving an external AC signal to stimulate a ground fault.
