Title: Renegotiated Bit-Rate Service System and Method
Inventor: GROSSGLAUSER MATTHIAS
IPC: H04L12/56
Filed: 1996-03-21
Abstract: A data transmission system and method employing either a renegotiated variable bit-rate ("RVBR") network or a renegotiated constant bit-rate ("RCBR") network. Within these networks, data transmission rates between a sender and a recipient are rapidly renegotiated as a function of previously stored data transmission rate information and system buffer levels. Such a system and method can be readily implemented within existing CBR and/or VBR network architectures. The RCBR and RVBR networks allow for the implementation of an intelligent data traffic management systems that are responsive to the rate at which new calls or requests for connections enter and leave the network, the frequency and duration of extended peak rate data bursts, as well as the occurrence of short duration data transmission peaks.

Title: Arrangement for impregnating webs of porous material
Inventor: DUERR WOLFRAM
IPC: D21H23/32
Filed: 1995-07-31
Abstract: In known pressure impregnating devices there is a chamber, which continuously narrows in the transport direction, between a cylinder around which the web to be impregnated loops, and the inner wall of a trough containing the impregnating agent. The impregnating agent is supplied to the chamber under high pressure, which is further increased in the chamber by dynamic effects.      Sealing problems arise at the inlet and outlet slits as well as at the front faces because of the high pressure. Disruptions in the operation can be created by fluff coming loose from the paper web as well as by impregnating agent penetrating between the sliding faces. The invention is intended to remedy these disadvantages.      With the novel device the seals have alternating narrow gaps and wide grooves (12, 23, 24) in the form of a labyrinth seal. The grooves (12, 23,,24) are provided with drain openings (14, 25, 26) for the impregnating agent flowing through (Fig. 1).

Abstract: A method and apparatus for securing an area and gaining access to the secured area includes a secure locking unit and a remote key unit. An unlocking sequence is initiated and a random coded signal is generated in the locking unit.          The random coded signal is transmitted to the key unit and simultaneously encoded with a predetermined encryption code in the locking unit to produce a master encrypted signal.          The transmitted random coded signal is received in the key unit and encoded with the predetermined encryption code to produce a slave encrypted signal. The slave encrypted signal is transmitted to the locking unit and compared to the master encrypted signal. When the master and slave signals compare, a signal is generated to unlock the area.

Title: Grain bin lid opener
Inventor: PHILLIPS KENNETH D
IPC: B65D90/10
Filed: 1996-10-04
Abstract: A grain bin lid opener designed to selectively open and close the lid from ground level. A single cable originates from the ground level on one side of the grain bin, proceeds over the grain bin and through the top part of a galvanized pipe and then extends down the other side. The cable is secured at the top part of the galvanized pipe which is welded to the grain bin lid. To close the lid, the cable is looped over a closing lever arm, located near ground level, which is then lowered therefore closing the lid. To secure the lid the lever arm is locked in a bracket. To open the lid the lever arm is released from the bracket and the cable is pulled from the other side of the grain bin. The grain bin lid opener allows the lid to be actuated from the ground level, thus preventing possible injury to a worker who would otherwise have to climb a tall grain bin to open the lid.

Title: Randomly ordered data block envelope tape format
Inventor: KAPLAN LAWRENCE
IPC: G11B5/008
Filed: 1997-01-10
Abstract: A method of writing data onto a magnetic tape storage medium in the form of data blocks and error correction code blocks. Data is received from a data source and formatted into data and error correction code blocks. Data entities are created from the data and error correction code blocks. Data envelopes are defined to include one or more such data entities. The data enve-lopes are sequentially written onto the magnetic tape medium. The data and error correction blocks within the data envelopes may be arranged in any order without regard to the physical channel or positional placement. Blocks containing user data and those containing internally generated error recovery information are freely intermixed with random duplications allowed. Block placement topology heuristics can be freely applied within envelopes, and are typically driven by error handling considerations. Block write errors are repeated and migrated into other data channels as necessary. Blocks within data envelopes are reordered when read from the magnetic tape storage medium and missing blocks are recovered according to conventional error recovery schemes. Data envelopes are well ordered thus providing data checkpointing, logical data append functionality, and overall synchronization.
