Title: Circuitry for mixed-rate optical communication networks
Inventor: WOOD STANLEY E
IPC: H04J3/16
Filed: 2001-07-24
Abstract: Circuitry for a node of an optical communication network has a mux and/or a demux. In one embodiment, the circuitry has a mux and a demux implemented on a single circuit board, where (1) the mux is configured to combine up to eight different incoming OC3/OC12-rate electrical signals into a single outgoing OC48-rate electrical signal for conversion into two copies of an outgoing OC48 optical signal and (2) the demux is configured to split a working incoming OC48-rate electrical signal (selected from two incoming OC48-rate electrical signals converted from two incoming OC48 optical signals) into up to eight different outgoing OC3/OC12-rate electrical signals. The node is configured to perform automatic signal provisioning, which may be (a) the addition of a new OC3/OC12 signal; (b) the deletion of an existing OC3/OC12 signal; (c) the rate-upgrading of an existing OC3 signal to an OC12 signal; or (d) the rate-downgrading of an existing OC12 signal to an OC3 signal. When adding a new OC12 signal or rate-upgrading an existing OC3 signal, the node automatically determines how to move existing OC3/OC 12 signals within the OC48 frame in order to accommodate the new OC12 signal. The node automatically communicates with the other node corresponding to the provisioned signal to automatically initiate corresponding signal provisioning at the other node.

Title: Activator for cyanacrylate adhesives
Inventor: SCHEFFLER INGOLF
IPC: C09J4/00
Filed: 1999-12-14
Abstract: Organic compounds containing the structural element -N=C-S-S- are suitable in dilute solution as activators for the accelerated hardening of cyanoacrylate adhesives. As compared with the known accelerators, they have the following advantage: good accelerating action, but they nevertheless permit a long waiting time between application of the activator and application of the adhesive. In addition, they avoid spontaneous, merely superficial hardening.

Title: Encrypted file retrieval method and device and computer-readable recording medium
Inventor: HAMADA TOMOHIRO
IPC: G06F17/30
Filed: 2001-09-21
Abstract: An encrypted file is constituted by an assemblage of records having a plurality of items, and at least key items among the plurality of items that are keys in a retrieval are encrypted. The expansion means of a retrieval device decrypts at least key items of each record of the encrypted file, attaches identifiers that indicate which records the key items belong to, and expands the decrypted key items and identifiers in a work area of a main memory. A retrieval means retrieves from the work area key items that satisfy retrieval conditions that are applied by the user, reads the appropriate original records from the encrypted file if retrieval succeeds, decrypts the records, and presents them to the user.
Patent CA-2365287-A1 (CA)
Title: Unscrambling and aligning conveyor
Inventor: PELKA RONALD EDWARD
IPC: B65G47/08
Filed: 2000-02-22
Abstract: An unscrambling and aligning conveyor (10) comprises a plurality of tapered rollers (50) attached to a pair of side supports (20, 30). The tapered rollers (50) are driven at a single speed and tapered to a minimum diameter (54) to define an alignment region (42). The tapered rollers (50) create a lateral speed decrease toward the alignment region (42) of the conveyor (10), causing separation and rotation of the articles (A, B, C), and thereby enabling the articles to be singulated in the alignment region (42). The tapered rollers (50) are supported by the side supports such that center axis of each roller (50) is horizontal to thereby defining a downwardly sloping article transport surface (40) which increases movement of the articles (A, B, C) towards the alignment region (42). The unscrambling and aligning conveyor (10) is driven at a speed greater than the input conveyor (14) located adjacently upstream thereof to provide articles with a gap therebetween so that articles (A, B, C) moving along the unscrambling and aligning conveyor (10) are properly singulated.

Title: A novel angiogenesis inhibitor
Inventor: PARK EUN JEONG
IPC: A61K38/00
Filed: 1999-09-15
Abstract: The present invention provides a novel angiogenesis inhibitor, LK68 whose amino acid sequence is identical with the human apolipoprotein (a) kringle domains IV36, IV37 and V38, a cDNA  sequence encoding the LK68, a recombinant expression vector comprising the cDNA, a recombinant microorganism transformed with the recombinant expression vector and a novel use of the LK68 as an anticancer agent and a method for treating angiogenesis-mediated disease. LK68, LK6, LK7 and LK8 exhibit inhibitory activities on the cultured endothelial cell proliferation as well as on the endothelial cell migration. LK68 and its single kringles also inhibit the normal development of capillaries in the chick embryo chorioallantoic membrane (CAM). It was also showed that systemic administration of LK68 causes the inhibition of primary tumor growth, which is correlated with a suppression of tumor-induced angiogenesis. Accordingly, LK68 protein, its single kringles or their functional equivalents may be applied for the development of a potent anti-cancer agent, which is highly effective for angiogenesis-mediated diseases covering cancer, rheumatoid arthritis, psoriasis, ocular angiogenic disease, etc.

Title: Threaded fastener nut with anti-cross threading radiused features
Inventor: NILSEN MARTIN J
IPC: F16B37/06
Filed: 2002-09-06
Abstract: A nut fastener is formed with anti-cross threading features that include a rounded or chamfered edge at the entry end to the nut, followed by an unthreaded cylindrical counterbore that extends axially from the entry end to the threaded section of the bore. The rounded or chamfered entry end prevents cross threading and the unthreaded section is of sufficient length to ensure substantially collinear alignment between the threaded fastener and the correspondingly threaded nut before threaded engagement occurs. An optional radiused portion is formed between the unthreaded and threaded sections of the nut to further prevent cross threading. In a preferred embodiment, the anti-cross threading nut is a weld nut formed with weld protrusions which enable the nut to be welded to a large structural member before mating engagement with a threaded fastener occurs.

Abstract: In a centrifugal flow blood pump, usable in left ventricular assist applications, blood is pumped from an inlet (16) to an outlet (22) by a primary impeller (18). A portion of the blood that enters the pump follows a  secondary channel (24) where a secondary impeller (70) routes the blood to lubricate a bearing between an impeller assembly (14) and a post formed by a  component of the pump housing. The unique shape of the secondary impeller (7 0) prevents blood stagnation and provides for a well-washed fluid bearing.</SDO AB>
