Patent CA-2294268-A1 (CA)
Inventor: CODATTO ANTONIO
IPC: B25J17/00
Filed: 1998-06-19
Abstract: A robot arm is supported by a pillar (14) rotatable about a vertical axis (A) and rotated by a reversible electric motor (88). The output shaft (90) of the motor (88) is connected to the pillar (14) by means of a mechanical reduction transmission which comprises a pair of planetary reduction units (62, 64). The driving members of both reduction units (62, 64) are fixed angularly to the output shaft (90) of the motor (88). The driven members (68, 70) of both reduction units (62, 64) are fixed angularly to the pillar (14). When the device is in operation, the peripheral rings (72, 74) of both reduction units (62, 64) are fixed to a structure (42) which supports the pillar (14). The angular position of at least one of the peripheral rings (72) is adjustable about the vertical axis (A) relative to the other ring (74) to enable the play in the internal gearings of the reduction units (62, 64) to be cancelled out.

Title: A continuous play gaming machine and a related method of gaming
Inventor: MCBRIDE SCOTT
IPC: G07F17/32
Filed: 2000-01-27
Abstract: A gaming machine accepts currency and indicates the number of credits available for use in wagering. As a convenience to the player, a continuous play feature is available, which when activated, automatically wagers and initiates play on behalf of the player. The time between automatic wagers may be adjusted by the player to suit the player's preference for a faster or slower game. A player becomes eligible to participate in certain larger shared prizes by making a sufficiently large qualifying wager. Once eligible, the player remains eligible for a predetermined grace period. According to a preferred embodiment, a countdown timer indicates the time remaining in the grace period. If the countdown timer reaches zero, the grace period has expired and the player is no longer eligible. A player can regain eligibility status by making a subsequent qualifying wager although this eligibility is not retroactive.

Abstract: A method and a system that allows verification of affiliation with any one or more of a set of affinity groups provides information about the conditions under which a benefit can inure to a supplicant who is found to be a member in good standing with a given group, or collection of groups. The system comprises a communication module that interacts with a party accessing the system and a processor that is coupled to information stores. The communication module is coupled to a processor that is also coupled to an information store. The information store is at least partly within the system. In some embodiments, parts of the information store are remote to the system. A party that is in the business of providing benefits connects to the system, identifies a supplicant, and specifies one or more affiliation groups. The processor searches the information store, determines whether the supplicant is a bona fide member of one of more of the specified groups, and is provided with information regarding the terms and conditions under which the supplicant might receive benefits from the party.

Title: Method for making low-density tissue with reduced energy input
Inventor: GUSKY ROBERT IRVING
IPC: D21F1/48
Filed: 1998-10-30
Abstract: A noncompressive dewatering device generates air streams that can be used to remove water from cellulosic webs in an energy efficient manner. Further, a wet-pressed machine can be modified to economically produce low-density tissue with an energy/capital efficiency greater than that of the throughdrying process. For instance, a cellulosic web can be non-compressively dewatered from a post forming consistency to a consistency from about 25 percent to the water retention consistency by passing air through the web with an Energy Efficiency at least 10 percent greater than that achievable using vacuum dewatering at the same speed. In particular embodiments, the web may be non-compressively dewatering to a consistency of at least 70 percent of the water retention consistency using about 13 or less horsepower per inch of sheet width, or to a consistency of at least 80 percent of the water retention consistency using about 30 or less horsepower per inch of sheet width, both at a speed of 2500 feet per minute or greater.

Abstract: A method and apparatus are provided for humidifying oxidant supplied to a fuel cell system, which can be a single fuel cell or a multiplicity of fuel cells. A  catalytic reactor is provided, which is supplied with a portion of the fuel and the oxidant. The oxidant is supplied in excess of the fuel to the reactor, so as to generate a stream of oxidant which is both heated and humidified. For an air breathing stack, this heated oxidant can simply be mixed with air flowing through the fuel cell stack. For a closed system, a heated and humidified oxidant flow, and optionally a fuel flow are mixed with additional flows of these gases supplied to the fuel cell.

Abstract: L'invention concerne un système d'extrusion à extrudeur simple (30) ou extrudeurs en tandem (102 et 103), et à mélangeur-refroidisseur (104), qui permet d'extruder un produit d'extrusion expansible à travers une filière (37) dans une enceinte close. Ledit produit, mis en forme et calibré à l'intérieur de la chambre (40), sort de cette chambre en continu pour venir au contact de l'atmosphère, via un orifice immergé dans un joint hydraulique d'immersion à chicane. Le joint considéré comprend l'orifice immergé et, en amont de cet orifice, un système de guidage en roue libre. Immédiatement avant le système de guidage, les paramètres du produit d'extrusion expansible sont détectés, de manière à pouvoir contrôler en permanence la configuration de l'orifice. Avant de pénétrer dans le joint hydraulique à chicane, ledit produit passe sur un rouleau fou flottant (65), dont la position contrôle un dispositif de tirage (par exemple, courroie sous vide), en queue de système, ce qui évite d'exercer une poussée sur l'extrudat.

Filed: 1998-04-01
Abstract: A modular articulated robot structure (fig. 4) composed of a series of independent modules (10, 100, 300) releasably connected to each other to form various configurations. The modules (10, 100, 300) may be of the rotary (10), linear (100), or wheeled (300) type. The rotary modules (10) are generally formed of first and second substantially U-shaped structural members (12, 14) pivotally attached to one another by means of a pair of axles or pivot pins (26) adapted to support a workload exerted on the module (10). A  motor (48) is mounted internally of the module (10) for pivoting the second structural member (14) relative to the first structural member (12). The motor (48) is connected to the second structural member (14) in such a way that it is not submitted to outside loads exerted on the module (10). Typically, the first and second structural members (12, 14) are provided with cooperating abutment surfaces (17, 19, 74, 76, 78, 80) for increasing the overall structural rigidity of the module (10) in certain positions thereof.

Un ensemble fond de puits comprend des éléments intérieur (60) et extérieur (84) mobiles l'un par rapport à l'autre et passant de positions fermée à ouverte et inversement afin, respectivement, d'assurer une étanchéité ou de compenser une pression différentielle dans une vanne unidirectionnelle (64) s'élevant lorsque la pompe est arrêtée. La pression sur la vanne unidirectionnelle peut être identique à la pression annulaire régnant entre le tube de production et l'ensemble fond de puits de l'installation hydraulique d'ascension artificielle. Des modes de réalisation de communication extérieure de la présente invention permettent la communication directe avec l'espace annulaire entre le tube de production et l'ensemble fond de puits de l'installation hydraulique hydraulique artificielle. Les modes de réalisation de communication intérieure de la présente invention permettent une communication à l'intérieur de l'élément extérieur par l'orifice de sortie de la pompe vers l'espace annulaire pour éviter les débris pouvant se trouver dans l'espace annulaire sous une lumière de refoulement de la pompe.
