Title: Electronic messaging system with multiple personal greetings
Inventor: FINK LAURENCE I
IPC: H04M3/533
Filed: 1991-01-17
Abstract: Abstract of the Disclosure An electronic messaging system allows a system subscriber to record a plurality of "customized" personal greetings which are played in response to incoming calls to the messaging system. Each of these greetings is placed in a message "pool" and a message system subscriber can specify the greeting that is to be played for each of a variety of call types. Each call type serves to differentiate between incoming communications based on one or more predetermined characteristics. Such call types, for example, may differentiate between incoming communications which are answered due to the called party not answering, or the called party being busy, or the call is received after normal working hours, or the call is an internal call, i.e., one that has originated on a local PBX or network of interconnected PBXs as compared to an "external" call which is of different origin. In addition, in a communications environment where an identification of the calling party is available, e.g., the telephone number of the communications device used by the calling party, each of a predetermined number of call types may be associated with one or more calling party identifications.

Title: Exponential function circuitry
Inventor: CHAN IVAN T
IPC: G06G7/24
Filed: 1991-01-30
Abstract: EXPONENTIAL FUNCTION CIRCUITRY                       Abstract of the Disclosure Circuitry and method for generating electrical currents representative of an exponential function of an input current.  The circuit includes an input diode chain and an output diode chain.  Each of the diodes in the input diode chain has an input current passing therethrough.  The input current is produced by an input current source connected in sources with the diode below the cathode of the diode.  A voltage driving circuit drives a voltage drop across the output diode chain that has a predetermined relationship to the voltage drop across the input diode chain.  The voltage drop across the output diode chain results in a current through the output diode chain.  The number of diodes in the output diode chain is preselected relative to the number of diodes in the input diode chain such that the current through the output diode chain is representative of an exponential function of the input current or currents.

Title: Flap opening mechanism and method
Inventor: BROWN MICHAEL A
IPC: B43M5/04
Filed: 1991-03-08
Abstract: ABSTRACT OF THE DISCLOSURE      An apparatus for producing items in selected configurations and a system and method for controlling the same.  More particularly, an apparatus for producing mail pieces and a system and method for controlling it to produce mail pieces in a variety of configurations are disclosed.  The apparatus includes a laser printer and folding sealing apparatus controlled by a data processor.  The folder sealer apparatus combines sheets printed by the laser printer with pre-printed sheets and envelope forms, which also may he printed by the laser printer or may be windowed envelopes, folds the sheets as necessary and folds and seals the envelope form about the folded sheets to produce a mail piece.  A user inputs a configuration for the mail piece which is translated by the data processor into a data structure and transmitted to the controller of the folder sealer apparatus.  The controller controls devices comprised in the laser printer and the folder sealer by executing state routines in accordance with the data structure to produce the mail piece in the defined configuration.  Concurrently the data processor transmits text from an output file to the laser printer for printing on printed sheets and envelope forms.  The data processor also controls the laser printer to print an address for the mail piece either on an envelope form or on a printed sheet in a position where it will be visible through the envelope.  Thus the apparatus is controlled to process an output file stored in the data processor into a mail run having a selected configuration.  A mechanism and method for opening the side flaps of an envelope form is also disclosed.

Filed: 1991-04-08
Abstract: 22 ABRÉGÉ DESCRIPTIF Étage amplificateur à tube hyperfréquence à large bande et faible dispersivité en fréquence Cet étage amplificateur comprend un tube hyperfréquence dans lequel un faisceau d'électrons (3) interagit avec une onde hyperfréquence de fréquence variable comprise dans une plage utile donnée, la vitesse des électrons du faisceau étant déterminée par une tension de cathode (Vk) appliquée au tube et l'onde hyperfréquence se propageant dans une structure à retard (4) lui imposant une vitesse de phase proche de la vitesse du faisceau d'électrons. Selon l'invention, la tension de cathode est une tension variable, régulée en fonction de ladite fréquence, cette tension variant avec la fréquence pour modifier la vitesse des électrons du faisceau de manière que, pour toute fréquence de ladite plage de fréquences utile, la vitesse correspondante de ces électrons reste essentiellement, mais non exactement, identique à la vitesse de phase de l'onde hyperfréquence. De la sorte, on compense la dispersivité en fréquence de la structure à retard et on maintient ainsi essentiellement constante la puissance délivrée en sortie par le tube. (Figure 1)

Abstract: ABSTRACT OF THE DISCLOSURE       An automatic molten substance bagging method and system which facilitates introduction and extrusion of molten substance into and from a fixed volume member and performs extrusion of molten substance rapidly by reduced driving force.  A carrying can in which a bag is received is first transported to a position below an injector, and vacuum attracting pads are moved toward and then away from each other on the opposite sides of the bag to attract by vacuum and open a mouth portion of the bag.  Then, the bag in the attracted condition is lifted by the vacuum attracting pads until a nozzle of the injector is inserted into the open mouth portion of the bag, and then the mouth portion of the bag is clamped by clamp members, whereafter the carrying can is lifted a little.  Then, molten substance is injected into the bag from the injector, and during such injection, the carrying can is lifted further.  After a predetermined amount of molten substance is filled into the bag, the bag is released from the clamp members, and then the carrying can is lowered to a vertical position at which the carrying can is subsequently transported away from the position below the injector.
