Title: Data protection system
Inventor: WATANABE SHINICHIROU
IPC: G06F21/12
Filed: 1995-04-21
Abstract: A data-protection system which permits authorized users to use a target data through a simple operation but does not permit unauthorized users to use the program even though they may be able to copy it. A dataprotecting system in which a center prepares a special algorithm which is secretly held by the center only, the center prepares a secret algorithm exclusively for the data and for the user by applying the center algorithm to the data and the user identifier which are inherent to the data and the user, and are well-known to the public and are used without any change, and supplies the secret algorithm to the user and to the data supplier and then when it happens that the data supplier must supply a data to the user, the data supplier prepares the same and a specific encryption key between the data that is to be supplied and the user by inputting the user identifier to the secret algorithm of the data that is to be supplied, encrypts part or whole of the data that is to be supplied directly or indirectly based on the encryption key and supplies it to the user, and the user prepares the same encryption key between the data that is supplied and the user based upon the data identifier that is supplied and his own secret algorithm and decrypts the encrypted data directly or indirectly.

Patent CA-2165342-A1 (CA)
Inventor: BUTLER BRIAN K
IPC: H04B1/707
Filed: 1994-06-20
Abstract: Système de détermination du débit de données codées dans le récepteur (12) d'un système de communications à débit variable. Les données sont reçues sous forme de symboles regroupés dans des trames. Lorsque le débit de transmission des données est maximal, la trame est remplie de symboles. Lorsque le débit de transmission des données est inférieur au débit maximal, les symboles sont répétés dans la trame jusqu'à ce qu'elle soit remplie, ou bien les symboles sont espacés les uns des autres à l'intérieur d'une trame. Lorsque le débit de codage est égal au quart du débit maximal, par exemple, chacun des symboles compris dans la trame est répété quatre fois, ou bien la transmission des données est quatre fois plus rapide. Les trames en entrée sont décodées, par exemple par un décodeur (48), puis codées de nouveau, par exemple par un codeur (76), pour chaque débit de données possible. Un comparateur (par exemple 84) compare les symboles de nouveau codés avec les symboles reçus initialement, et un compteur (par exemple 100) compte le nombre d'erreurs de symbole. Chaque processus de décodage produit une indication de la qualité du processus de décodage, qui peut renfermer les résultats d'un contrôle de redondance cyclique (CRC) tel que le CRC (120), ou des mesures de qualité de Yamamoto. Le total des erreurs et l'indication de qualité comportent une mesure d'erreurs qui est transmise à un processeur, par exemple le microprocesseur (56). Le processeur analyse la mesure d'erreurs pour chaque débit de données et détermine le débit auquel les symboles en entrée ont le plus probablement été codés.

Inventor: CHAKRABARTY TAPANTOSH
IPC: B03B9/02
Filed: 1995-12-21
Abstract: A process for upgrading heavy oil and bitumen includes deasphalting the bitumen by de-watering the bitumen/water emulsion to a water concentration of from about 0 to about 20% by volume. A surfactant is added to the de-watered bitumen/water emulsion to form a stable asphaltene-in-water emulsion as a separate phase from the deasphalted bitumen. The surfactant is preferably non-ionic and, more preferably, an ethoxylated alkyl phenol. In accordance with the present invention, the viscosity of the bitumen is significantly reduced and the quality of the bitumen is improved. The asphaltene is recovered in a useable form which can be used as a source of fuel at the production site and which additionally can be used to enhance the recovery of the bitumen from the rock formation.

Inventor: SHAW THOMAS J
IPC: A61M5/31
Filed: 1994-09-07
Abstract: A nonreusable medical device has a needle (34) for injecting or collecting fluid which is retractable by depression of a plunger (54) slidingly mounted in the medical device. A front-mounted retraction mechanism (22) has a needle holder connected to the needle. The needle holder is supported along the axis of the device by means of a frictionally engaged retainer ring (102) member coupled to the needle holder along an axially aligned sliding interface, The needle holder and retainer ring are positioned in the front portion of a hollow body. The front of a movable member or plunger presses against the retainer member passing around the needle holder which cannot move forward, thereby separating die retainer member from the needle holder. The separation occurs by gradually inducing the extent of the sliding interface area until the retainer member pops loose from the needle holder whereupon the needle holder and needle are retracted into a cavity in the plunger in response to a retraction force applied to the needle holder by a previously compressed spring.

Title: Apparatus for transloading load units between railway vehicles and road vehicles and vice versa
Inventor: WIEDECK HANS-NORBERT
IPC: B65G67/02
Filed: 1996-04-15
Abstract: An apparatus for transloading of load units between rail vehicles and road vehicles utilizes a railway roadway and a road vehicle roadway which are parallel to one another and a transport stretch in the form of a conveyor on which the load units can travel as well as parallel to the two roadways.  A transloading unit, for example, a portal load handling unit can also travel along a path parallel to these roadways so that the load unit can be picked up from the railroad vehicle while the latter and the transloading unit are moving together, i.e. at zero relative speed and can set down the load on the transport stretch where the load continues to move with the transloading unit.  Conversely, a load traveling along the transport stretch can be picked up by the transfer unit which is likewise traveling along that stretch and deposit it upon a railway vehicle without bringing the latter to standstill and again at zero relative speed.
