Title: Method of operating a drive system and device for carrying out the method
Inventor: FURRER FRANZ
IPC: G05B19/425
Filed: 1997-06-03
Abstract: A drive system and a method of operating such a system are specified. The drive system comprises at least two drive groups having a plurality of drive controllers of controlled drives. The drive controllers of a drive group are synchronized via a drive bus by means of a local synchronization clock, and the local synchronization clocks are made equal to a global synchronization clock via a drive data network connecting the drive control means. The plant-wide synchronization of the drives via a global signal enables a drive system to be equipped with a virtually arbitrary number of drives. As a result of the fact that the desired values are preferably likewise transmitted synchronously, based on the global synchronization clock, between the drive control means via the drive data network, it is also the case that no time errors occur during the desired value transmission. The invention is preferably used for rotary printing machines.

Title: Method for verifying the expected postage security device and its status
Inventor: RYAN FREDERICK W JR
IPC: G07B17/00
Filed: 1997-11-20
Abstract: A secure and reliable method for verifying in the host system that the expected PSD is coupled to the host system includes generating a random number in the host system and encrypting the random number with a PSD state identification number. The encrypted random number is then sent to the PSD. The PSD decrypts the encrypted random number received using the PSD state identification number and sends the decrypted random number to the host system. The host system compares the decrypted random number received from the PSO to the random number generated in the host system. If they are the same, the host system has verified the expected PSD and has also verified that the PSD has not completed any transactions apart from the host system. A method for verifying that the expected host is coupled to the PSD mirrors the method for verifying the expected PSD.

Title: Multi-step digital signature method and system
Inventor: HUANG STUART T F
IPC: G06Q20/00
Filed: 1996-04-19
Abstract: A multi-step signing system and method uses multiple signing devices (11, 13, 15, 17, 19) to affix a single signature which can be verified using a single public verification key. Each signing device possesses a share of the signature key and affixes a partial signature in response to authorization from a plurality of authorizing agents (23, 25, 27, 29, 31). In a serial embodiment, after a first partial signature has been affixed, a second signing device exponentiates the first partial signature. In a parallel embodiment, each signing device affixes a partial signature, and the plurality of partial signatures are multiplied together to form the final signature. Security of the system is enhanced by distributing capability to affix signatures among a plurality of signing devices and by distributing authority to affix a partial signature among a plurality of authorizing agents.

Title: Gasification process and plant for direct reduction reactors
Inventor: JAHNKE FREDERICK C
IPC: C22B5/12
Filed: 1998-04-16
Abstract: The present invention is an integrated process and apparatus for supplying at least a portion of the reducing gas feedstock to a reduction reactor, such as a reactor for the direct reduction of iron, wherein the reducing gas contacts a feed material at a mean operating gas pressure and effects reduction of the feed material to provide a reduced product.          The integrated process includes gasifying a hydrocarbonaceous feedstock in a partial oxidation reaction to produce a synthesis gas which comprises hydrogen, and carbon monoxide at a pressure substantially greater than the mean operating gas pressure in the reduction reactor. The synthesis gas is expanded to lower its pressure to substantially the mean operating gas pressure in the DRI reduction reactor to thereby form the reducing gas feedstock at the pressure conditions used for the DRI reaction. The lower pressure reducing gas mixture generated by the expansion is introduced into the DRI reactor as part or all of the reducing gas requirement for the direct reduction of iron.
