Abstract: Procédé et appareil destinés à réduire les attaques des constituants nuisibles de suspensions de particules solides sur des surfaces de transfert thermique dans des chambres de transfert thermique se trouvant dans des réacteurs à lit fluidisé. Selon l'invention, on prévoit une chambre de dilution (16) contenant un lit de particules solides (16') circulant dans le système. La chambre de dilution est disposée dans l'écoulement de particules en amont de la chambre de transfert thermique (18) afin d'inactiver les impuretés nuisibles par rapport aux surfaces de transfert thermique (46) dans ledit écoulement de particules et/ou pour séparer les impuretés de ce dernier. Les particules solides sont déchargées de la chambre de réaction dans la chambre de transfert thermique en passant par la chambre de dilution, de sorte que l'écoulement de particules solides soit nettoyé de ses constituants nuisibles.

Title: Method of locating hydrophones
Inventor: GIKAS VASSILIS NICHOLAS
IPC: G01V1/20
Filed: 1998-12-23
Granted: 2007-09-25
Abstract: A method of computing the location of air guns and hydrophones within a seismic spread utilizes a navigation network having a plurality of stations. The network provides a plurality of navigation observations. A number of the observations consist of magnetic bearings which are used to derive the hydrophone locations. The method includes the steps of: a) obtaining a set of observations from the network, each observation being obtained by using navigation devices whose origin system moves independent of the navigation reference point; and b) forming a design matrix wherein the magnetic bearings are modeled based on the equation (I). (see formula I)
Patent CA-2260773-C (CA)
Inventor: DUYAR AHMET
IPC: G01M99/00
Filed: 1997-06-20
Granted: 2002-09-10
Abstract: the present invention relates to a model-based fault detection system and method for monitoring and predicting maintenance requirements of electric motors. Since the method and system of the present invention is software based and utilizes data obtained from non-intrusive measurements, implementation costs are significantly less than prior art maintenance methods. The system comprises computer means coupled to sensors which provide continuous real-time information of the input voltage and current and motor speed. The system and method utilize a multivariable experimental modeling algorithm to obtain a mathematical description of the motor. The algorithm compares the modeled result with a measured result and quantifies the comparison in terms of a residual which is generated by subtracting the respective signals. A  diagnostic observer analyzes the residual and determines if the motor is fault free or operating in a manner other than fault free. Upon detection of the impending fault, the diagnostic observer evaluates the measured variables of the motor, determines the deviation from the reference value and develops a diagnosis of the likely failed or failing component. Another embodiment of the present invention is particularly useful in the manufacture of fractional horsepower electric motors and especially in the performance of quality control testing.

Abstract: A nosepiece for directing a charge into a crucible of a furnace. The nosepiece comprises a completely enclosed sleeve which more accurately directs the charge into the crucible. The sleeve has a distal portion that deflects the charge toward a center area of the crucible, thereby minimizing impact of the charge on the top edge of the crucible and its refractory finer. In addition, the nosepiece is split so that the distal portion is movable, thereby to provide access to an interior of the nosepiece.  As a result, any bridging in the charge may be addressed by moving the distal portion to an open position.

Abstract: In a working method for the separate packaging of different types of food in a single package, food is placed on a tray (3) with different compartments (5, 7, 9) open on one side, with one type of food being placed in each compartment. Subsequently a film structure film (11) is placed above the open sides of the compartments, with a part (21, 23, 25) of the film structure being placed above each compartment. Then the film structure (11) is fastened to the tray (3) around the openings of the compartments.  To optimize the conditions in which the food is packaged for each type of food, the film structure (11) is comprised and/or processed such that the characteristics of the specified parts (21, 23, 25) of the film structure are different from each other. These circumstances can be improved even more by first determining, before comprising and/or processing the film structure (11), the characteristics of the food and then executing the composition and/or processing of the film structure (11) depending on the characteristics of the food.

Abstract: A molecular motor in which multiple concentric cylinders (or nested cones) rotate around a common longitudinal axis. Opposing complementary surfaces of the cylinders or cones are coated with complementary motor protein pairs (such as actin and myosin). The actin and myosin interact with one another in the presence of ATP to rotate the cylinders or cones relative to one another, and this rotational energy is harnessed to produce work. The concentration of ATP  and the number of nested cylinders or cones can be used to control the rotational speed of the motor. The length of the cylinders can also be used to control the power generated by the motor.
