Abstract: A method for the simultaneous modernisation of a plant for ammonia synthesis and a plant for urea synthesis, provides -inter alia - the arrangement of a carbamate synthesis section and a carbamate decomposition section, in order to obtain a predetermined amount of carbamate in aqueous solution and of hydrogen and nitrogen in gaseous phase which are fed to the existing sections for urea synthesis, respectively ammonia synthesis. Thanks to this method of modernisation it is possible to remarkably increase the production capacity and at the same time to reduce the energy consumption of the urea and ammonia plants without being forced to replace or anyway overload the existing sections of decarbonation, methanation and compression, in general.

Abstract: On contrôle la performance de systèmes d'administration d'agents bénéfiques à un animal de façon à établir la vitesse d'administration de l'agent bénéfique et à s'assurer du bon fonctionnement du dispositif d'administration de l'agent bénéfique. Pour ce faire, il est possible de contrôler la configuration physique du dispositif d'administration osmotique implanté depuis l'extérieur du corps de façon à déterminer la quantité d'agent bénéfique administrée et/ou la vitesse d'administration de l'agent bénéfique. Ce contrôle de la configuration physique peut être mis en oeuvre de différentes manières, par exemple par contrôle fluoroscopique ou aux rayons X de la structure implantée ou par détermination magnétique du positionnement d'un piston situé à l'intérieur du dispositif implanté. Il est également possible de contrôler la performance du système au moyen d'un marqueur intégré à l'agent bénéfique qui génère une réponse susceptible de faire l'objet d'une détection spécifique et pouvant être mesurée de manière non invasive dans des fluides corporels ou des produits dérivés.

Granted: 2005-02-08
Abstract: The present invention is directed to a method and apparatus which utilizes a software-based digital signal processing circuit to generate a signal which is representative of the status of a movable component. A preferred embodiment of the apparatus of the present invention includes a synchro which is connected to a movable component. An analog reference excitation may be applied to the synchro, and the synchro generates analog synchro signals which bear a relationship to the status of the movable component. The analog synchro signals are converted to digital synchro signals by a plurality of analog-to-digital converters. A digital reference signal and the digital synchro signals are provided to a software-based digital signal processing circuit which preferably corrects constant and time-varying errors in the digital synchro signals and generates a status signal which is representative of the status of the movable component. For instance, the status signal may represent the angular position of the movable component.  A different embodiment of the status signal may represent the angular velocity of the movable component.

Title: Minimally invasive medical retrieval device
Inventor: BAGLEY DEMETRIUS H
IPC: A61B17/22
Filed: 1999-03-19
Granted: 2007-05-22
Abstract: A minimally invasive medical retrieval device (10) useful for the removal of objects such as stones, calculi, concretions, foreign bodies and the like from the urinary, biliary, vascular or other systems includes a sheath (12) containing at least three wires (14) adjacently disposed in the sheath (12). At least one of the wires (14), and preferably all of them, can be moved longitudinally with respect to the sheath (12). The wires (14) have distal portions (16) which are formed so as to allow the engaging and removal of the object or objects. The distal portions (16) of the wires (14) preferably form a helical basket (22 or 40) particularly adapted for engaging urinary stones, calculi and concretions. Other grasping and manipulating shapes are useful as well. The wires (14) are substantially wedge-shaped in cross-section and substantially fill the entire cross-sectional area of the interior (26) of the sheath (12). The wedge-shaped wires (14) can be partly contained within a stainless steel cannula (28) positioned in the sheath (12). The sheath (12) can be of very small diameter, significantly smaller than the diameters of existing retrieval or extraction devices, preferably from about 0.5 to about 6.0 French. Unexpectedly, despite these small diameters, the baskets, graspers and the like into which the wedge-shaped wires (14) are formed simultaneously exhibit good resistance to twisting and bending, while being capable of being formed into shapes (such as helical baskets) not normally achieved with flat wires.

Abstract: A waved disk (3) for use in a friction engaging apparatus has toothed portions (3a) along an outer or inner edge thereof, and is bent or undulated in a direction of the plate thickness with the circumferential direction as the direction of a wave length. In manufacturing the waved disk (3), there is used a press with a stationary die (100) and a movable die (200). The stationary die (100) has a plurality of radially elongated pressing portions (101) raised from the surface of the stationary die (100) so as to correspond to highest portions (3b) of mountains of the wave. The movable die (200) has a plurality of radially elongated pressing portions (201) raised from the surface of the movable die (200) so as to correspond to lowest portions (3c) of valleys of the wave. A disk blank (3') made up of an annular flat plate having a toothed portion (3a) along an outer or inner edge thereof is pressed between the stationary and movable dies (100, 200) for being pressed in the direction of the plate thickness. By means of guide members (102) provided in the stationary die (100) for phase-positioning, the disk blank (3') is fixed in phase so as to be positioned circumferentially away from each of the pressing portions (101, 201) of the stationary and movable dies (100, 200), respectively. Press forming is performed in this state. Deviations in wave height and in load characteristics are thus prevented.

Title: Adjustable-backset latch system for locksets, and method
Inventor: WINARDI MICHAEL
IPC: E05B55/00
Filed: 2000-08-11
Granted: 2010-04-06
Abstract: An adjustable-backset latch system for a lockset includes three main subsystems; a bolt retraction system (12), a backset-adjustment system (14), and a deadlatching system (16). By virtue of thesimplicity of the design of the backset adjustment subsystem, theuser can change the backset from 2-3/8" to 2-3/4", and vice-versawith one hand. A pin (76) is simply moved through a "U"-shaped slot (68) formed in a housing (34) and the housing and bolt actuation components are extended simultaneously by the desired backset increment. The bolt retraction system of the present invention uses a cam (40) in which the distance from a point (42) about whichthe cam rotates and the end of the cam, and the distance to a smaller cam pin (46), are selected to multiply the relatively small angular distance transversed during a half-round rotation of the knob or handle into the desired retraction distance of a main bolt. The deadlatching system uses two springs (52, 54), one of which not only biases an auxiliary bolt (20) to its extended position, but also biases a deadlocking dog (118) so as to pivot into a blocking position preventing the main bolt from being retracted completely, in the event an intruder attempts to move the bolt.

Abstract: The invention is a method for simulating one or more characteristics of a multi-component, hydrocarbon-bearing formation into which a displacement fluid having at least one component is injected to displace formation hydrocarbons (Fig. 1, item 5). The first step of the method is to equate at least part of the formation to a multiplicity of gridcells (Fig. 2, item 10). Each gridcell is then divided into two regions, a first region representing a portion of each gridcell swept by the displacement fluid (Fig. 3, item 16) and a second region representing a portion of each gridcell essentially unswept by the displacement fluid (item 17). The distribution of components in each region is assumed to be essentially uniform. A model is constructed that is representative of fluid properties within each region, fluid flow between gridcells using principles of percolation theory, and component transport between the regions. The model is then used in a simulator to simulate one or more characteristics of the formation.
