IPC: C07D407/12
Filed: 2000-02-14
Granted: 2006-10-10
Abstract: Disclosed are baccatin derivatives of the formulas (I) and (III)   (wherein R1 and R2 are an OH-protecting group, R3 is aryl or alkyl, R5 is H or alkyl, n is 1-5, Bz is benzoyl and Ac is acetyl) as well as processes for producing the baccatin derivatives by reacting a baccatin of the formula (II)   with a (.beta.-ketoester in the absence of a catalyst or in the presence of a tin compound or an amine base, preferably under reduced pressure. The baccatin derivatives are useful for producing anti-cancer toxoid compounds.

Title: Timer
Inventor: AMONETT DANIEL KEITH
IPC: H01H43/10
Filed: 2000-07-28
Granted: 2006-05-23
Abstract: A cam-operated timer for a household appliance has a variety of improvements. An audible and tactile feedback member engages a textured surface on the cam wheel, to produce desired audible and tactile feedback when the timer is manually set.      When the timer is manually set, the cam-actuated switches are moved away from the cam surfaces, and a clutch is opened to permit bi-directional slip between the cam wheel and motor, so that the sole source of audible and tactile feedback is the audible and tactile feedback member. The timer also features lanced switch arm contacts, that provide a sharp contact edge to permit the switch arms to make good contact with adjacent switch arms. The switch arms are mounted in a stack of wafers, where each wafer may have switch arms of differing thickness or metal, allowing high current and low current switches to be mixed.      Features in the housing are used to receive and locate the wafers to prevent inaccuracies in wafer thickness from accumulating through the stack of wafers. Also, the motor and geartrain are reduced in size. The motor comprises a stator plate and a rotor mounted for rotation in the stator plate. The geartrain comprises meshing gears positioned on both opposite sides of the stator plate and mounted directly to the stator, for providing a gear reduction of the rotation of the motor.

Title: Preformed wire guide
Inventor: MORRIS EDWARD J
IPC: A61B5/00
Filed: 1999-08-19
Granted: 2008-11-18
Abstract: A preformed anchoring wire guide (10) for medical procedures such as renal angioplasty. The wire guide (10) includes a preformed bend (14) having an angle (15) with respect to the longitudinal axis (28) that corresponds with the takeoff angle of the renal artery (23) relative to the aorta (33). This preformed bend (14) allows easier access to the ostium (22) of the renal artery (23) and allows the distal portion (27) of the wire guide to anchor within the artery (23), thereby improving trackability of a balloon angioplasty catheter (21), reducing the need for a guiding catheter, and reducing the likelihood of vessel damage or thrombus shear due to forces that are normally exerted against the wall of the vessel (33) by a standard wire guide. The wire guide is comprised of a lubricious polymer-coated (19) superelastic memory alloy mandril (11), such as a nickel-titanium alloy, having a tapered distal portion (20) over which a flexible tip portion (12) comprising spring coil wire is attached to provide radiopacity and safety to the vasculature. The distal portion (27) of the wire guide is further made atraumatic by the addition of a hook-shaped or "J" tip (29). Additionally, the nickel-titanium alloy mandril is cold-worked in its austenitic by overstressing the wire in a fixture, thereby shifting a t least part of the crystalline structure to martensite within the region of the preformed bend (14). The cold-worked nitinol wire guide has improved resistance to dislodgement and deformation by an advancing catheter while still retaining its desirable superelastic properties.

Abstract: - Méthode pour modéliser des écoulements dans un milieu fracturé traversé par un réseau d'objets conducteurs de fluides de géométrie définie mais non homogénéisables à l'échelle de chaque maille du modèle (des grandes fractures, des failles sub- sismiques par exemple, cles couches sédimentaires très perméables, etc.). - La méthode permet de simuler des écoulements de fluides dans un milieu géologique poreux fissuré de structure connue que l'on discrétise par un maillage et que l'on modélise en considérant que chaque volume élémentaire du milieu géologique fissuré est constitué d'un milieu fissure et d'un milieu matrice équivalents à l'échelle de chaque maille entre lesquels on détermine les échanges de fluides. La méthode comporte une détermination des échanges intervenant entre le milieu matrice et le milieu fissure, et une modélisation des transmissivités des différentes mailles traversées par chaque objet conducteur, de façon que la transmissivité résultante corresponde à la transmissivité directe le long de cet objet conducteur. On évite ainsi d'avoir à faire une modélisation explicite de ces objets qui s'avère prohibitive à l'échelle d'un champ du fait du nombre très élevé de mailles impliquées et des contraintes numériques. - Applications à l'évaluation de réservoirs d'hydrocarbures.

Title: Improved cdma soft hand-off
Inventor: CORBETT EDDIE
IPC: H04W36/32
Filed: 1999-12-14
Granted: 2009-10-13
Abstract: A system and method for improving soft hand-off in a CDMA system uses mobile station location and velocity information to maintain soft hand-off legs with those cells in which the mobile station is more likely to be located. The system and method of the present invention estimates the weighted probability of the mobile station arriving in neighboring cells and produces "bias" values for those cells that the mobile station is more likely to be entering or to be located in.  These bias values are used for modifying signal quality values for those cells, and for determinig whether the current cell or neighbor cells are to be placed in an active set so as to establish, or maintain, soft hand-off legs. The system and method of the present invention thus chooses those cells which are more likely to be retained as soft hand-off legs and therefore reduces the overall number of soft hand-offs.

Abstract: A test system (10) is coupled to a control system (20) in a manner which allows the test system to communicate with and drive the control system by sending and receiving signals via both the controller-I/O communication channel (160) and the field I/O connectors (225). The test system (10) is used to both simulate a plant to be controlled and t o monitor, validate, and/or modify the internal state of the control system controller and possibly the control system I/O interface (220). Plant simulation is accomplished by simulating the I/O devices to which the control system (20) is coupled (and hence the plant processes) whe n installed in the operational environment. In addition to the simulation of I/O devices, the test system (10) takes advantage of the fact that many commonly used controller and I/O interfaces are capable of communication with other devices by using such communications ability to provide instructions to or obtain information from a control system's controller(s) and I/O interface(s).

Abstract: An aftermarket retrofit kit is used to prepare control arm bosses of automotive suspension systems to receive new, replacement ball joints. The kit includes a special cutting tool for forming obtuse threads in the apertures of aluminum suspension system mounting bosses for replacement of spent or used steel ball joints originally pressed-fit into forged aluminum control and steering arms. Since unthreaded apertures of bosses of control and steering ann joints in which the original pressed fitted equipment ball joints may be threaded to receive the new joints, avoidance of having to replace expensive original control and steering arms is made possible by the reuse of such arm parts normally discarded. A separate alignment block is included to assure accurate piloting of the cutting tool. Threading of the control aim bosses can be done on or off of the vehicle, and separate kits are provided for upper and lower control arms.
