Title: Rolling door with a flexible door leaf
Inventor: SIEWERT HOLGER
IPC: E06B9/58
Filed: 1998-09-02
Granted: 2006-08-08
Abstract: A rolling door with a flexible door leaf which can be wound is rotationally mounted above the door opening and driven by a winding shaft. A closing strip whose length is smaller than the clearance width between lateral profiles at the door opening is fastened on the lower end of the leaf. A cable to tighten the door leaf has fasteners at each end and extends above reversing rollers mounted in the floor area.  Carriage-like blocks move vertically guided by the lateral profiles. Holding means detachably connect the blocks to the closing strip ends and have openings for the cable extending from the reversing rollers on the floor to the closing strip. After a crash, holding means comprising catching devices release the closing strip upon exertion of lateral forces and re-engage therewith when the blocks are pressed down so the rolling door automatically and easily returns to operation.

Title: Implement hitch
Inventor: MOSDAL BRIAN THOMAS
IPC: B60D1/14
Filed: 2000-09-05
Granted: 2004-07-20
Abstract: A hitch link structure includes two hitch tubes angled with respect to each other and having forward ends connected by upper and lower hitch plates welded to the tubes.  The plates include weld cutouts designed so the same plates can be used with a variety of different hitch tube angles, depending on the width of the mainframe hitch mount-up.  Three apertures in the forward end of each of the plates receive bolts which connect the selected hitch link to the plates. The apertures also act as weld fixturing locators to speed hitch construction. The weld cutouts, in generally a half moon configuration, facilitate low cost fillet welds at easily accessible locations regardless of hitch tube angle and facilitate fillet weld connections in relatively lowly stressed areas. The lower plate is apertured to define an intermediate support hole for the safety chain, and the central bolt connecting the hitch link also attaches to the safety chain so the chain is accommodated without additional parts.

Abstract: A process and device for the laser treatment of the internal surfaces of hollow bodies such as engine blocks with cylinder bores which consist of the matrix alloys such as a light-metal or aluminum. wherein a wear-resistant coating is applied to the working surfaces of the pistons within the cylinder. A probe enters the cylinder and includes the laser beam which produces a beam spot on the internal surface of the cylinder and applies an alloying powder at the focus of the spot using a continuously conveying protective gas. The probe is displaced along the axis of the cylinder and simultaneously rotated while the alloying powder is melted in the spot of the laser beam to a depth sufficient to form a wear-resistant coating which will not break loose during the normal operation and life of the engine block. The engine block can be fixed in a stationary position while the probe or probes move simultaneously within the cylinders to apply the hardened surface coating.

Title: Method and apparatus for preventing scaling in electrodeionization units
Inventor: TESSIER DAVID FLORIAN
IPC: C02F1/469
Filed: 1999-09-24
Granted: 2010-05-25
Abstract: A method and apparatus is provided for inhibiting scaling in an electrodeionization system and, more particularly, for increasing tolerance to hardness in the feed water to an electrodeionization unit by inhibiting precipitation of scale-forming metallic cations contained in the feed water and thereby increasing efficiencies of the electrodeionization system. Water to be purified is passed through an electrodeionization unit in which the flow in the diluting compartment is countercurrent to the flow in the concentrating compartment. This is to impede the migration of scale-forming metallic cations from the diluting compartment, through the cation exchange membrane, into the concentrating compartment and towards the concentrating compartment side of the anion exchange membrane, thereby preventing scale formation on the anion exchange membrane. The electrodeionization unit may be further modified by dividing the concentrating compartments into first and second compartments by a porous diaphragm or ion-conducting membrane. The porous diaphragm or ion-conducting membrane effectively eliminates convective transport of scale-forming metallic cations from the cation exchange membrane side of the concentrating compartment to the anion exchange membrane side of the concentrating compartment, thereby inhibiting scale formation on the anion exchange membrane.

Abstract: An electronic document classification system for classifying electronic documents received through a network is provided. The classification system comprises a criteria table for storing predetermined criteria for items included in the electronic documents and a score counter provided corresponding to each of the electronic documents. For each of the items included in the electronic documents, the classification system compares the item with a corresponding criterion stored in the criteria table, obtains a score based on the comparison result, and adds the obtained score to the score counter. Therefore, the resultant value of the score counter indicates a sum of the scores obtained for the items included in the electronic document corresponding to the score counter.  The classification system assigns a priority to each of the electronic documents in accordance with the value of the score counter corresponding to the electronic document. Thus, the electronic document received through a network are prioritized.

Abstract: A highly scalable key management architecture for secure client-server systems used in IP telephony network, wherein cryptographic state needs to be saved only by the clients. This architecture takes advantage of existing key management protocols, Kerberos with the PKINIT (public key) extension, to provide an IP telephony system having a high degree of scalability. In the case of lost security associations, the architecture provides for lightweight rekeying operations that allow clients to quickly re-establish the lost association or switch to a different server. The key management architecture includes a method for establishing a secure channel between an IP telephony endpoint and Server in an IP telephony network. The endpoint is coupled to a user and the Server is coupled to the IP telephony network. The method comprises steps of transmitting from the endpoint to a key distribution center a request for a security ticket, receiving the security ticket from the key distribution center, transmitting from the endpoint to the Server a request for a sub-key, receiving the sub-key from the Server, and establishing a secure channel between the endpoint and the Server using the sub-key.
