Abstract: ABSTRACT OF THE DISCLOSURE      An apparatus and control system 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 be 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 system for processing mail pieces having a non-standard configurations is also disclosed.

Abstract: Carbonate polymers (PC) such as randomly branched carbonate polymers and blends thereof with linear carbonate polymers are blended with ABS polymers and MBS polymers which enhance the melt strength of polymer composition. The ABS polymers have less than 40 weight percent rubber and greater than 18 percent by weight acrylonitrile. The MBS polymers have greater than 40 weight percent rubber and an outer polymer shell made from alkyl(meth)acrylates. This locates the MBS rubber modifier in the PC phase and in the PC/ABS interface so that higher melt elasticity is achieved and the compositions are therefore useful in blow molding and thermoforming applications.

Title: Escalator handrail reentry guard
Inventor: MOLDENHAUER DETLEV B
IPC: B66B29/04
Filed: 1992-02-10
Abstract: Abstract Escalator Handrail Reentry Guard The reentry port where an escalator handrail passes out of view at the exit newel of the escalator is provided with an elastomeric reentry guard in the form of a collar surrounding the handrail.  The collar has an elastomeric bumper part which is accessible from the exterior of the assembly, and which is mounted on a holder assembly which is contained inside of the escalator skirt housing.  The holder and bumper are mounted for limited lateral movement concurrently with the handrail, and such movement is controlled by rollers mounted on the holder assembly, which rollers contact the sides of the handrail.  The result is that lateral movements of the handrail as it moves past the reentry guard cause like lateral movements of the housing assembly and bumper.  The handrail thus will not rub on the bumper, thereby providing a safer and longer lasting reentry guard.
