Title: Procede de chiffrement d'information et dispositif pour la mise en oeuvre du procede
Inventor: MISCHENKO VALENTIN ALEXANDROVI
IPC: H04L9/08
Filed: 1999-04-27
Abstract: L'invention concerne un système de protection d'information contre tout accès non autorisé par des moyens électroniques. Pour transformer l'information initiale, le dispositif comporte une unité de transformation (4), une unité de prise de décisions (3), une unité de stockage de communication reçue (6), un commutateur (8), et une unité de stockage d'information auxiliaire (7). Pour coder et transférer l'information, le destinataire est équipé préalablement d'une clé relative aux communications reçues, et il dispose d'un certain nombre d'informations sur les régularités correspondant aux valeurs de la communication qui lui est adressée: ainsi, des valeurs spécifiques de l'information initiale correspondent à l'ensemble des symboles de cette information. En l'occurrence, le destinataire est muni préalablement d'une série de fonctions de transformation Y1, Y2,, YN = Yi(X), où X = {x1, x2,xm} est une pluralité de symboles spécifiques de l'information transformée. Au cours du traitement de l'information chiffrée, l'entrée de l'unité de prise de décisions (3) introduit les données relatives au nombre (n) de cycles de transformation de la communication initiale. Avant le début du cycle de transformation courant, l'unité de prise de décisions (3) envoie un signal de commande au générateur de nombres aléatoires (5), ce qui a pour effet d'engendrer un nombre aléatoire (Ri) pour transmission à la base de données (2) puis à l'unité de transformation.

Title: Dispositifs antibasculement pouvant equiper des moyens de transport sur roues comme les fauteuils roulants, et procedes associes
Inventor: KIRBY RONALD LEE
IPC: A61G5/10
Filed: 2000-04-28
Abstract: On décrit un dispositif antibasculement (100) servant à régler l'angle de basculement autorisé d'un appareil, tel qu'un moyen de transport sur roues, notamment un fauteuil roulant (10), dans un sens avant, arrière ou latéral. Le dispositif antibasculement (100) comprend un boîtier (104) fixé à un châssis ou structure de support (15) de l'appareil et dans lequel un bras de support (102) est fixé rotatif. Le boîtier (104) est configuré de telle sorte que le bras de support (102) est placé soit en position de repos soit en position de service. La position de repos ccorrespond généralement à un état de non basculement de l'appareil, et dans la position de service, le boîtier entre en prise avec le bras de support. La prise du bras de support (102) sur le boîtier, ajoutée au fait que l'extrémité distale (103) est en contact avec la surface d'appui, bloque la rotation du bras de support (102) et empêche un basculement supplémentaire de l'appareil (10). Lorsque l'appareil (10) est basculé dans un sens avant, arrière ou latéral, le bras de support (102) tourne automatiquement à l'intérieur du boîtier (104) et se dégage de sa position de repos en réponse au basculement de l'appareil (10). Le boîtier (104) comprend en outre un mécanisme de réglage du basculement qui régle sélectivement la distance angulaire entre la position de repos et la position de service, et donc le degré de basculement. Dans une forme de réalisation spécifique, le mécanisme de réglage comprend une came (120) couplée rotative au boîtier (104), si bien qu'une surface de la came vient au contact d'une surface du bras de support (102) lorsque celui-ci est placé dans la position de service.

Inventor: TOMASZEWSKI KRIS
IPC: E05B65/12
Filed: 2003-08-20
Abstract: A power actuator ässembly for a latch includes first and second articulated levers (24, 30). The first lever includes cam follower surfaces (32A, 3213) and the second lever includes at least one stop member (28) which pivots between first and second positions as each lever (24, 30) travels between first and second positions. A motor-driven cam (16) having driving members (18A, 1813) and stop members (20A, 2013) drives the first (24) lever. More particularly, each driving member (18A, 1813) has a path of travel that engages one of the cam follower surfaces (32A, 3213) for a portion of the travel path to drive the first and second levers and is in disengaging alignment with the cam follower for another portion of travel. The cam stop members (20A, 2013) abut the stop member (28) of the second lever (30) when the cam driving members (18A, 1813) are in the non-aligned position, whereby the levers may be activated without driving the cam (16). The assembly can be employed, inter alia, in a lock application or a power release application so as to preclude the necessity of having to backdrive the power actuator.

Title: Snowmobile
Inventor: YOSHIOKA YOSIHARU
IPC: B62D55/00
Filed: 1989-11-15
Abstract: ABSTRACT     A snowmobile of the saddle-riding type utilizes essentially the same upper structure as a motorcycle but mounts a ski on the front fork for steering and an engine-driven endless belt track assembly for powering the device.  The endless belt track assembly is arranged for mounting on an articulated rear swing arm structure in order to maintain surface contact between the endless belt and the snow and thereby improve the operating efficiency of the vehicle.  An improved endless belt construction is described in which the belt is strengthened by core members and the driving cogs of particular configuration and disposed at prescribed locations with respect to the propelling lugs in order to maintain surface contact between the belt edge and the snow surface during cornering.  Also disclosed are various forms of cover structures for the track assembly that prevent the scattering of snow from the belt onto the rider or vehicle parts.          Grab rails attached to the rear swing arm elements facilitate manipulation of the vehicle in confined spaces.

Title: Process and system for recovering oil from oil bearing soil such as shale and tar sands and oil produced by such process
Inventor: THIRUMALACHAR M JEERSANNIDHI
IPC: E21B43/16
Filed: 1990-02-01
Abstract: ABSTRACT OF THE DISCLOSURE           In a first aspect, oil bearing soil, such as oil shale or tar sands, is contacted in a contacting zone with a liquid medium comprising water and a lipo-philic solvent which is miscible or soluble with water.          In a second aspect, the medium can include a yield improving agent comprising a water soluble acidic ionic salt or a water soluble ionic acid.  The contacting produces an emulsion which comprises the oil from the oil bearing soil and the liquid medium.  The inorganic portion of the soil is dispersed in the emulsion and it is separated from the emulsion by gravity or other suit-able means.  The emulsion is broken by an emulsion breaking agent into two phases.  The two phases are allowed to separate into two layers.  The first layer comprises the oil and minor amounts of the liquid medium. The second layer comprises the liquid medium and minor amounts of the oil.  The first layer is then recovered.          The medium from the second layer can be recycled into the contacting zone.         In a third aspect, tar sands are contacted first with a liquid medium comprising an intimately mixed phase emulsion of a immiscible solvent and an aqueous solution containing a surfactant and a non-caustic alkali compound.  The bitumen released is recovered and the remaining sand is contacted with a second liquid medium comprising an aqueous solution containing a surfactant and a non-caustic alkali com-pound.  The bitumen further released is recovered.          Additional contacting of the remaining sands with addi-tional volumes of the second liquid medium may provide further recoverable bitumen.
