Filed: 1987-05-07
Abstract: A process enables production of ethanol, butyl alcohol, acetone, lactic acids and glycerine from substrates normally not fermentable during a single fermentation stage by the simultaneous addition of hydrolysing and immobilizing enzymes and flock-type bacteria in a tower reactor. For this purpose enzyme flocks are produced having similar physical properties to those of bacteria flocks, and they are introduced with the latter in the tower reactor. The reactor comprises a widened end piece and a cylinder inserted in the latter so that the product which overflows out of the cylinder is in a non-turbulent region. The enzymes thus remain in the reaction chamber and the bacteria become richer without the need for filters or membranes.

Title: Access to content addressable data over a network
Inventor: CARPENTIER PAUL R
IPC: G06F17/30
Filed: 1999-01-23
Granted: 2003-10-16
Abstract: Representing a number of assets on an originating computer begins with selecting the assets to be represented (102). Cryptographic hash asset identifiers are generated (104); each of the asset identifiers is computed using the contents of a particular asset. The asset identifier is a content-based or content-addressable asset name for the asset and is location independent. An asset list is generated that includes the asset identifiers computed from the assets (106). A cryptographic hash asset list identifier is generated that is computed from the asset list (108). The asset list identifier is stored for later retrieval. The assets selected are also stored for safekeeping either locally or on a computer network. In the event of loss of the files from the originating computer, the asset list identifier is retrieved (302). Using the asset list identifier, the original asset list is found and retrieved from its safe location (306). The asset identifiers from the retrieved asset list are used to find and retrieve the individual assets from their backup locations (314, 316). The assets are verified by recomputing the cryptographic hash asset identifier for each asset retrieved and comparing it to the asset identifier from the asset list (316). The MD5 algorithm is used for the cryptographic hash function. Assets are retrieved using a multicast protocol (402). A series of importer programs (702-710) searches for assets to retrieve in progressively more remote locations. Assets are retrieved whole or in segments (606).

Granted: 1994-11-22
Abstract: EFFICIENT CONNECTION ARRANGEMENTS        FOR MULTIHOP NETWORKS Abstract This invention is a Local Area Network (LAN) which comprises a plurality of NIU's, each arranged to transmit on a separate set of frequencies and to receive on a separate set of frequencies. During operation, a data packet is multihopped from a source NIU, through intermediate NIUs, until reaching an NIU which can transmit a frequency which the destination NIU is capable of receiving. The packet is then forwarded to the destination NIU. The source NIU may also send a control packet and cause the destination NIU to adjust its receive frequency so that subsequent packets may be transmitted directly to the receiving NIU. In an alternative embodiment, the multihopping may be accomplished using specialized headnode modems.

Title: Mail piece weight quality control system and method
Inventor: METELITS STANLEY E
IPC: G07B17/00
Filed: 1990-12-28
Granted: 2001-02-27
Abstract: This invention relates to a system for certifying the accuracy of postage payments based on the weights of mail pieces. The expected weight of each mail piece is determined and a mail processing unit receives data relative to the contents to be inserted into an envelope that together form the mail pieces. A high speed weighing scale is located downstream from the mail processing unit to receive the mail pieces after the mail processing unit has inserted selected materials into envelopes. A comparison is made between the expected weight of each mail piece and its measured weight. If the measured weight of a mail piece is found different than the actual weight beyond certain tolerances, it could be rejected. If a large number of mail pieces exhibit a divergence between the estimated weight and the actual weight, the mail processing unit will be disabled and an examination made to determine what caused the discrepancies in the weights. If there is correlation between the anticipated weights and the measured weights, the mail pieces are placed in trays or other suitable containers to be delivered to the Post Office. A history of mail runs and their accuracy with regard to weight is maintained for record purposes.

Title: Hub adn interface for isochronous token-ring
Inventor: BASSO CLAUDE
IPC: G06F13/00
Filed: 1993-03-12
Granted: 1999-02-16
Abstract: A hub featuring several ports for attachment of stations to a LAN comprises concentration logic for the handling of multiplexed incoming and outgoing Token-Ring and isochronous flows  from  and  to  the  stations.    The  concentration  logic comprises  a  clock  recovery  logic  from  incoming  Token-Ring packet data stream, for regeneration of Differential Manchester encoded data on output, and recovering of Token-Ring clock.  A cycle framing generator receives a 125 us synchronization clock (local or remote) from the hub backplane, and the Token-Ring clock, and generates control signals to each of the 10 ports. Each port is made up of a port transmit interface, and a port receive interface.   Data from a station hooked to the hub is input to port receive interface. Token-Ring packet Differential Manchester encoded data are output on to the next active port, and specifically  to its port transmit interface, along with a recovered strobe  clock,  while  isonchronous  (ISO)  data  are output to a switch.   The switch receives a hub local clock, which otherwise distributes on the whole concentration logic. Isochronous  traffic  interchange  with  the  hub  backplane  is ensured through leads 410 and 411; inbetween ports or between ports and the hub is ensured thru leads 407 and 409 replicated for each port.  Data to the station hooked to the hub is output from port transmit interface. Differential Manchester encoded data are received along with Token-Ring clock. Control signals are input.  Isochronous data are received.   Token-Ring packet Differential Manchester encoded data are finally output from the concentration logic.
