Patent CA-2317273-A1 (CA)
Inventor: WILLIAMS RANDALL DALE
IPC: B42F13/24
Filed: 2000-08-30
Abstract: A lock for the rings of photo albums and other binders includes a lock and a security component to prevent opening of the album in a retail store and to prevent pilferage of the contents or the improper insertion of refill pages. Once a consumer has made an album selection, the security component is removed.      Once removed, the lock is moveable between a first position in which opening of the album rings is permitted and a second position in which opening of the rings is prevented. The initial release of the security component preferably requires a tool. In the most preferred embodiment, the lock slides in a slot in a binder body and includes a lower ridge which aligns with an opening in a pair of spring plates to permit ring opening. When the ridge is moved away from the opening and into the cavity of the binder body, the rings cannot be opened.

Inventor: MIZIKOVSKY SEMYON B
IPC: H04L9/08
Filed: 2001-01-12
Abstract: A system for updating a communications keys) performs an authentication(s) of the unit and/or of the communications system using an update key. By using the update key to perform the authentication(s), the key update system can reduce communications between a home communications system and a visiting communications system by sending the update key to the visiting communications system while maintaining the communications key at the home communication system. For example, in performing a key update, the home communications system generates a communications key, such as a new authentication key SSD-A-NEW, using a sequence RANDSSD generated at the home communications system and a secret key A-KEY maintained at the home communications system and at the unit. The home communications system generates the update key SSD-KEY also using the sequence RANDSSD and the secret key A-KEY. The home communications system sends the update key SSD-KEY and the sequence RANDSSD to the visiting communications system, and the visiting communications system sends the sequence RANDSSD to the unit. The unit generates the new communications key, such as the new authentication key SSD-A-NEW, and the update key SSD-KEY in the same manner as the home communications system. Because the visiting communications system has the update key SSD-KEY, the visiting authentication system can generate the signature value(s) AUTHSSD and/or AUTHBS using the update key at the visiting communications system to authenticate the unit and/or the communications system.

IPC: C12C13/10
Filed: 2000-02-19
Abstract: Cuve de brassage qui a été mise au point pour offrir sur le marché un appareil de brassage à une seule cuve, doté de deux unités filtre extérieures et d'un dispositif de chauffe extérieur. Selon la présente invention, une partie médiane (1) sans fond est reliée aux deux couvercles creux (2, 3) par l'intermédiaire de joints d'étanchéité (4) à fermetures de serrage annulaire (5). Du fait qu'aucun élément filtre placé au fond n'arrête l'apport de chaleur, ladite cuve de brassage peut être chauffée depuis l'extérieur par l'intermédiaire des couvercles creux (2, 3). A la fin d'un processus partiel de brassage, un disque de filtrage est monté dans les ressorts tendeurs (6) du couvercle creux supérieur, puis il est poussé avec la matière à filtrer jusqu'au couvercle inférieur et introduit dans les ressorts tendeurs (6). Le couvercle creux rempli est alors amené vers le haut par rotation de la cuve de brassage. Après démontage et nettoyage, ladite cuve peut être équipée d'un dispositif mélangeur et de dispositifs de mesure en vue de la deuxième partie du processus de brassage. Grâce à sa conception et à sa simplicité d'utilisation, ladite cuve de brassage est tout à fait adaptée pour l'amateur souhaitant brasser lui-même sa bière du fait que l'appareil selon la présente invention offert sur le marché est peu onéreux.

Title: Polyamine treatment of neurological disorders
Inventor: MURPHY MICHAEL A
IPC: A61P25/28
Filed: 1998-08-21
Abstract: 2,3,2 Tetramine (3,7-diazanonane-1,9-diamine) is propounded for the treatment of Parkinson's Disease and demential characterized by mitochondrial damage in view of this compound's ability to completely neutralize the dopamine-depriving effect of MPTP in laboratory animals up to 12 hours post MPTP injection, and to retain partial protection at suboptimal tissue levels for up to 36 hours. The effect of injecting combinations of MPTP and/or reducing agents and/or xenobiotics and/or depigmenting agents on Dopamine, Norepinephrine, Serotonin and Epinephrine levels demonstrated that MPTP and MPP+ act as reducing agents that mobilize copper and calcium, and sequester iron, and that the vulnerability of dopaming to these types of neurotoxins and to xenobiotics and metals can be corrected by administration of 2,3,2 tetramine that appears to redistribute metals between diverse storage pools and free metals in cytosol and regulate receptor mediated events, among other antidotal effects analogous to those of some of the endogenous polyamines.

Title: An agile network protocol for secure communications with assured system availability
Inventor: SCHMIDT DOUGLAS CHARLES
IPC: H04L47/43
Filed: 1999-10-29
Abstract: A plurality of computer nodes communicates using seemingly random IP source and destination addresses and (optionally) a seemingly random discriminator field. Data packets matching criteria defined by a moving window of valid addresses are accepted for further processing, while those that do not meet the criteria are rejected. In addition to "hopping" of IP addresses and discriminator fields, hardware addresses such as Media Access Control addresses can be hopped. The hopped addresses are generated by random number generators having non-repeating sequence lengths that are easily determined a-priori, which can quickly jump ahead in sequence by an arbitrary number of random steps and which have the property that future random numbers are difficult to guess without knowing the random number generator's parameters.  Synchronization techniques can be used to re-establish synchronization between sending and receiving nodes. These techniques include a self-synchronization technique in which a sync field is transmitted as part of each packet, and a "checkpoint" scheme by which transmitting and receiving nodes can advance to a known point in their hopping schemes. A fast-packet reject technique based on the use of presence vectors is also described. A distributed transmission path embodiment incorporates randomly selected physical transmission paths.
