Title: Av synchronous cardiac pacing system delivering multi-site ventricular pacing triggered by a ventricular sense event during the av delay
Inventor: JURAN CARLEEN J
IPC: A61N1/362
Filed: 2000-10-27
Abstract: A pacing system for selectively sensing spontaneous ventricular cardiac depolarizations at first and second spaced apart ventricular sites during the time-out of an AV delay and delivering pace pulses to the spaced apart ventricular sites in a triggered pacing mode. The first and second ventricular sites are preferably right ventricular (RV) and left ventricular (LV) pace/sense electrode sites, and RV event and LV event signals are sensed at the RV and LV pace/sense electrodes A V-A pacing escape interval and a ventricular refractory period, a trigger pace window, an upper rate interval and further post-event time periods are started upon a RV or LV sense event or a first ventricular pace pulse delivered upon time-out of the AV delay. A  triggered ventricular pace pulse or pulses is delivered to one or both of the RV and LV pace/sense electrode sites upon detecting an RV sense event or LV  sense event during the AV delay. In one triggered pacing mode, a RV or LV pace pulse is delivered upon a RV or LV sense event during the AV delay to one of the RV or LV pace/sense electrode sites. In another triggered pacing mode, a triggered pace pulse is delivered to the other one of the RV or LV pace/sense electrode sites after a triggered pacing delay timed from a non-refractory RV  or LV sense event occurring during the AV delay. In still another triggered pacing mode, a first pace pulse is delivered upon a RV or LV sense event, the triggered pacing delay is timed out, and a second pace pulse is delivered to the other one of the RV or LV pace/sense electrode sites after time-out of the triggered pacing delay. Triggered ventricular pacing is disabled during the V-A escape interval. Such a system could be employed in pacemakers that are part of a cardio defibrillator system if desired.

Title: Process for the production of furfural from lignosulphonate waste liquor
Inventor: ZEITSCH KARL J
IPC: C07D307/48
Filed: 2000-04-14
Abstract: A process for the production of furfural from lignosulphonate waste liquor which contains pentose is described, the process essentially comprising the maintenance of a boiling condition of the liquor at predetermined pressures for a sufficient time to convert the pentose to furfural and for the furfural produced to be removed without reacting with pentose, lignosulphonate or itself. Hot air or some other gas under pressure or hot mercury may be used to maintain the boiling of the liquor to ensure that the furfural produced transfers from the liquid to the gas phase and is transported from the reactor in the gas stream. Apparatus for carrying out the process includes a columnar reactor (4) with means (8) to control the pressure, an inlet for preheated liquor, an inlet for hot air under pressure at a low level, an outlet for spent liquor and an outlet for the gaseous phase, from which the furfural is recovered.

Filed: 2000-07-17
Abstract: An expandable stent prosthesis is disclosed in which the apices of the bends located at at least one end of the stent are individually twisted at an angle to the circumference of the stent to form a fan blade-like arrangement when viewed from that end. The fan blade-like arrangement allows the stent to expand from the compressed condition during deployment such that likelihood of a strut or bend of the stent become entangled with a barb or adjacent strut or bend, is reduced. In one embodiment of the invention, the fan blade-like arrangement results from plastically deforming the individual apices, while in another embodiment, the apices are twisted into the fan blade-like arrangement during the loading process, such as by use of a suture thread to pull the apices into alignment.

Title: Void forming and anchor positioning apparatus and method for concrete structures
Inventor: KELLY DAVID L
IPC: E04G15/04
Filed: 2002-06-25
Abstract: A void former for positioning an anchor within a concrete structure is comprised of a hollow polymeric body having first and second sections hinged together for movement between a closed condition engageable around the anchor received therebetween and an open condition in which the sections are separated at the lower portions thereof to release the anchor received therebetween. The void former is monolithically formed by injection molding and includes integrally formed latch elements on the respective sections for mutual engagement to secure the sections in the closed condition and a bridge between the sections to provide a hinged connection therebetween. In the injection molding process the sections are formed so as to be positioned in the open condition. Upon removal from the injection mold, the sections are hinged relative to one another by bending the bridge therebetween, before the polymer is fully cured. Such bending aligns the molecules of the polymeric material within the bridge to enable the bridge to serve as a hinge and sustain repeated bending.

Title: Apparatus and method for inspecting non-round containers
Inventor: NICKEY GEORGE A
IPC: B65G47/86
Filed: 2002-07-23
Abstract: An apparatus for inspecting non-round containers includes a pair of carriages coupled to associated motors for rotation independently of each other on a common axis. Each carriage carries a corresponding plurality of semi-circular gripping fingers, which may be moved toward and away from each other by controlled rotation of the carriages. The fingers are widely separated from each other to accept non-round containers at an in-feed station, and to permit removal of the containers at out feed and reject stations. For transporting the containers between stations, the fingers are brought closely together to grip the containers for indexing, and springs on one of the carriages resiliently urge the associated fingers toward the fingers on the opposing carriage for accommodating size variations among the containers. At inspection stations, the fingers are moved slightly away from each other, but remain together so as to define a circular perimeter for capturing the non routed body and confining the body of the container during rotation. The container may be rotated by a drive roller engaged with the cylindrical container finish. The container finish can be inspected, as can portions of the sidewall, base and heel.

IPC: C12P21/04
Filed: 2001-01-17
Abstract: Mammalian progenitor or stem cells are expanded in vitro by increasing the levels of .beta.-catenin in the cell. The expanded cells substantially maintain their original phenotype including the ability to give rise to multiple types of differentiated cells. The intracellular levels of .beta.-catenin may be manipulated by providing exogenous .beta.-catenin protein to the cell, or by introduction into the cell of a genetic construct encoding .beta.-catenin. The .beta.-catenin may be a wild-type or stabilized mutant form of the protein. Preferably the long term cell culture medium substantially lacks stromal cells and cytokines.
