Abstract: A dictation system having two or more recording units, each selectively operable as a dictation unit or a transcription unit, and including a selector for selecting a respective unit for recording or transcription. A unit selected for recording dictation is enabled if a record medium therein is ready, or initialized, for recording; otherwise the unit is enabled for transcription. While one unit operates to record dictation, the other may operate simultaneously to transcribe previously recorded dictation. In a system having at least three recording units, at least two are identified with respective, particular identities and the third is designated a spare recording unit. After a predetermined amount of dictation has been recorded on any one of the identified recording units, further dictation destined for that identified unit is recorded on the spare unit, and the identity of the spare unit is charged over to be equal to the identity of the recording unit for which dictation had been intended.

Abstract: A moistening apparatus for moistening a form sheet. The apparatus includes a body having a trough in its top portion and a reservoir in its lower portion. A capillary tube connects the trough with the reservoir and a roller co-extensive with the trough, is mounted so that its lower portion is substantially surrounding by the trough. The apparatus is connected to a source of fluid by a gravity feed. The fluid level in the source varies between a predetermined upper and predetermined lower level such that at the lower level, fluid is always maintained in the reservoir, while at the upper level the fluid does not rise substantially above the bottom of the trough. Thus, a meniscus of fluid is maintained in the trough only by capillary action. As a form sheet moves transversely across the roller, the roller rotates through the meniscus of fluid and a sheet of fluid is transferred to the form sheet to moisten a previously applied remoistenable glue on the form sheet.

Abstract: A method and apparatus for generating cryptographic keys for a postal manifest and for synchronizing cryptographic keys for transmitting postal data securely on a communication link is presented. The techniques for generating a key and for synchronizing keys use the same apparatus but use slightly different data to create a cryptographic key.The postal data center maintains a unique set of data for each server station. Using this set of data along with a manifest sequence number (or communication transaction number) and the date, a cryptographic key is created. Each server station stores a fixed master key, KO, a permutation table, Pt, and ID, and GMT date. Using the manifest sequence number (or the communication transaction number) a row of the permutation table is altered and the master key KO is scrambled with the permutation table top get a new key K2. With K2, the date, server ID, and manifest sequence number (our communication transaction number) are encrypted.

Abstract: A dictation transcription system having a recording/playback module and a display module which are detachably connectable to form an integral structure. The display module provides a visual display of the length, locations and types of messages by storing and utilizing display data. This display data is generated during a dictate operation and, when dictation is "finished", the display data is recorded on the record medium. Subsequently, and preferably, prior to transcription of the dictated messages, the record medium is scanned for the display data which then controls a transcriptionist's display module to reproduce the visual indication originally derived during dictation.
