Abstract: MAILING SYSTEM FOR MIXED WEIGHT MAIL                 Abstract of the Disclosure A mailing system for metering batches of mixed weight mail.  The system includes a demand feed for singulating mailpieces, a weighing module for weighing the singulated mailpieces and determining the appropriate postage amount and a postage meter responsive to the weighing module for metering each singulated mailpiece with the appropriate postage amount.  A transport system sequentially transports singulated mailpieces from the feeder to the weighing module when the postage meter is set then stops during the weighing period.  The postage meter is set for the next sequential mailpiece only after weighing and metering are both completed.  In another embodiment a mechanical buffer is provided between the weighing module and the meter to allow overlapping of weighing time with meter setting time.  In still another embodiment the weighing time is reduced by a modified weighing algorithm which uses a reduced number of samples to determine the weight of a singulated mailpiece when the initial indication of weight is not close to a breakpoint in the postal rates.  In another embodiment of the invention the postage meter is modified to initiate common preliminary meter setting functions in response to the presence of a mailpiece on the weighing module and before the appropriate postage amount is determined.

Title: Message fifo buffer controller
Inventor: LEFEBVRE MARTIN C

Granted: 1991-07-16
Abstract: MESSAGE FIFO BUFFER CONTROLLER Abstract of the Disclosure A FIFO (first in first out)  control circuit for providing address  information to a FIFO memory.   Two up counters are used; one to provide the write address and one to provide the read address.   A multiplexer selects which addresses (read or write) are used.   Two storage registers are used to temporarily "hold" the output from the counters. This enables the counters to be re-loaded with their original "count" to enable either a re-reading or a re-writing of a message stored in the FIFO memory.  Logic circuitry is used to provide two status output signals, namely full (or not) and empty (or not).

Title: Process for simultaneous production of sulfur from h_s-containing gases and so -containing gases
Inventor: LELL RAINER
IPC: C01B17/04
Filed: 1987-12-16
Granted: 1994-01-11
Abstract: ABSTRACT     The invention relates to a continuous production process in which elementary sulphur is obtained simultaneously from H2S-gases as well as from SO2-gases in various quantity ratios.  In the presence of considerable quantities of the SO2-gas, all of the H2S-gas is partially being oxidized with a O2-gas in a 1st reaction zone at 800 - 1400°C, whereas the balance of the SO2-gas is partially being reduced in a 2nd zone at 1000 - 1500°C in the presence of a reducing gas.  Subsequently the mixture from both zones, which has now an almost stoichiometric H2S:SO2 ratio, is being converted to sulphur in a 3rd zone at 800 -1300°C without any additional, direct heat supply.  The sulphur is separated by way of condensation and the remaining gas mixture is further processed in a conventional Claus installation.

Abstract: Abstract A calligraphic writing system of the type including an x-y plotter, a writing pen and a digital computer that controls the movement of the pen relative to the writing bed of the plotter.          The system self-aligns the writing pen and items on the bed being written, and permits a number of items to be correctly positioned on the writing bed and to be written during a single cycle.  The pen draws positioning marks on the writing bed, thereby insuring that the item(s) to be written on and the pen are properly aligned relative to each other.  In embodiments in which a plurality of items (all of which may or may not be the same) may be written in one cycle, the computer determines how many sets can be placed on the writing bed at once, and draws positioning marks for each item of each complete set that will so fit.

Abstract: METHOD AND APPARATUS FOR CONTROLLING ACCESS          TO A COMMUNICATION SYSTEM     Abstract All subscribers operating within a communication system initially generate and transmit a random password and their ID code to the operation control) center of a communication system. Thereafter, in a first embodiment, subscribers are commanded to modify (in a predetermined manner) and re-transmit their password and ID code either periodically or upon requesting access to the communication system. The modified password is retained as the current (authorized) password by both the subscriber and the system; In a second embodiment, subscribers are commanded to generate and transmit a new random password and their ID code to the system, which maintains a history of each subscriber's current and previous passwords. According to the invention, some of the subscribers having an unauthorized (duplicated) ID code may be inactive (off) when the subscriber is commanded to modify or generate a password. In this way, one of the subscribers having an unauthorized (duplicated) ID code will become out-of-sync with the system, and eventually transmit an unauthorized password. When the system receives an incorrect password for an out-of-sync subscriber, access to the communication system may be denied, and the subscribers that duplicate (or permit others to duplicate) ID codes may be identified.
