Abstract: In a data communication network which includes terminals interconnected via a central switch, a process for verifying the identity of a terminal user who is provided with secret data associated with his identity. In carrying out the verification process, the secret data is first encrypted at the terminal under a transfer-in key for transmission to an associated data processing system. When it is determined that the terminal user maintains an account at the associated data processing system, a first translate operation is performed to translate the data from encryption under the transfer-in key to encryption under an authentication key, both of which keys are protected under other keys which are different from each other, thereby providing an authentication parameter which may be used to verify the identity of the terminal user.

Abstract: An apparatus and method for the production of molding compositions for fiber-reinforced resin composites in which chopped fiber tow is fluidized, expanded and admixed with dry powdered resin is disclosed. Fluidized fibers are conveyed through a flow accelerating device and discharged into an enlarged mixing chamber wherein turbulent admixing with powdered resin injected therein occurs.

Abstract: An improved method for verifying the identity of a prospective terminal user presenting an identification card or a credit card and a memorized personal identification number. Only part of the information necessary to correlate an account number to a personal identification number is available at any accessible place in the operating system. Neither the credit card, the host computer, nor the transmission link will ever have sufficient information to completely correlate an account number to a personal identification number.
