Inventor: PAULENCO MARY
IPC: A45C11/04
Filed: 2000-03-15
Abstract: The invention relates to a panel within an eyeglass case that serves a dual purpose namely: to accommodate a storage pocket for storing various eyeglass accessories such as a lens cleaning cloth, lens cleaning kits of wet towelettes, cleaning fluid, monocles, magnifying loupes, folding readers, folding sunglass clip-ons, chains, cords, and eyeglass repair kits; and also to separate the temple arms from the lens frame of the folded eyeglasses thus preventing abrasive damage. The panel with storage pocket can be included in any standard eyeglass case configuration. A conventional eyeglass case protectively encloses a pair of eyeglasses in a folded position where two hinged temple arms are rearwardly folded in overlapping relation on a lens frame. The eyeglass case has a first wall and a second wall, each wall being joined together along at least one wall edge defining an eyeglass enclosing compartment. The panel of the invention projects from at least one wall into the compartment a distance sufficient to separate the lens frame from the folded temple arms. The panel has a storage pocket with an access opening either outside the case or from inside the compartment.

Abstract: La présente invention concerne un procédé et un appareil permettant de déterminer le prochain routeur auquel un paquet de données est transmis, sur son trajet, à un hôte destinataire en traversant une table d'acheminement à l'aide d'un moteur de recherche matériel et un arbre de recherche unique. La traversée de chaque noeud de l'arbre de recherche prend seulement un cycle de mémoire, ce qui divise en deux le temps qu'il faut pour chercher une table d'acheminement et donc les paquets de données sur un système de réseaux d'ordinateurs. Ceci s'effectue en stockant le bit de décision de chaque noeud dans un noeud parent plutôt que dans le noeud lui-même. Cet appareil peut utiliser un moteur de recherche matériel pour rechercher la table d'acheminement.

Title: Process and device for manufacturing forms of packaging
Inventor: LOHWASSER WOLFGANG
IPC: B29C51/08
Filed: 2000-04-25
Abstract: A process for manufacturing packaging (12) with good barrier properties against passage of water vapour and gases is such that recesses are shape-formed in a film-shaped material (22) to act as containers (26) to accommodate contents. After cutting the shape-formed film into individual units of packaging (12), these are coated in vacuum with materials exhibiting the desired barrier properties. A device for carrying out the process comprises a shaping station (14) for shape-forming the containers (26) from the film-shaped material (22), a cutting station (16) for cutting the packaging (12) out of the shape-formed, film--shaped material (22), and a vacuum-coating station (18) for coating the packaging (12).  The process and the device make it possible to manufacture e.g. light-transparent blister packs within a packaging line, whereby the good barrier properties against passage of water vapour and gases can be achieved using relatively cost-favourable starting materials.

Title: Purification and microsequencing of hyaluronidase isozymes
Inventor: STERN ROBERT
IPC: G01N33/573
Filed: 1998-11-12
Abstract: The present invention is based on the purification and sequencing of isozymes of plasma hyaluronidase (pHAse) found in urine. Specifically, urine contains two hyaluronidases (HAses): 1) a 57 kDa HAse that is apparently the same as the 57 kDa HAse found in plasma; and 2) a 45 kDa HAse, which is found in urine but not plasma. The smaller urine isozyme is composed of two disulfide-linked polypeptides produced by endoproteolytic cleavage of the 57 kDa isoform. The present invention thus features a urinary hyaluronidase (uHAse) polypeptide and nucleotide sequences encoding a Chain A polypeptide and a Chain B  polypeptide, the two polypeptides of which uHAse is composed. In a particular aspect, the uHAse is a human uHAse (huHAse), preferably a huHAse composed of the Chain A and B polypeptides having SEQ ID NOS:2 and 4, respectively. In related aspects the invention features polynucleotide sequence encoding Chain A and Chain B polypeptides, preferably having the sequences of SEQ ID NOS:1 and 3, respectively. In addition, the invention features polynucleotide sequences that hybridize under stringent conditions to SEQ ID NOS:1 and 3. In related aspects the invention features expression vectors and host cells comprising polynucleotides that encode uHAse polypeptide Chains A and B. The present invention also features antibodies that bind specifically to uHAse, and methods for producing uHAse.

Abstract: An area weapons effect simulation system and method that determine the extent of simulated injuries and damage sustained by players (105) such as soldiers and vehicles as a consequence of simulated mines, projectiles, air defenses, and toxic or nuclear clouds in near real time. The system uses a distributed architecture that simulates the effect that area weapons would have on each player in real time or near real time, thus allowing players to determine the consequences of their tactics and actions as a part of a combat training exercise. Player Units are pre-loaded with information which allows them to determine the probability of damage or injury, depending on the type of player, defensive measures taken on the part of the player, and the type of weapon being simulated. Alternatively, such information may be down-loaded to each Player Unit as necessary.
