Title: Method for fracturing and propping a subterranean formation
Inventor: JONES LLOYD GARNER
IPC: E21B43/04
Filed: 1995-06-01
Abstract: A method for fracturing and propping a thick and/or homogeneous fracture interval (12) of a subterranean formation which is traversed by a wellbore (11). A workstring (20) is lowered into the wellbore (11) and a fracturing fluid is flowed into either or both ends of the fracture interval annulus (33a) (i.e. that portion of the well annulus which lies adjacent the fracture interval) to initiate a fracture (A). The flow of fracturing fluid is continued into one end of the annulus (33a) while a slurry containing proppants is flowed into the other end of the fracture interval annulus (33a). During flow of fracturing fluid and slurry into the annulus (33a), slurry and/or fracturing fluid is also delivered through alternative flowpaths (26) to different levels within said fracture interval (12). This is continued until all of the levels or zones of the fracture interval (12) have been fractured and propped.

IPC: H04Q11/04
Filed: 1996-11-05
Abstract: An unbundling apparatus to permit competitive access providers access to telephone lines connected to a remote terminal, and the ability to control and test such lines.  Such unbundling apparatus includes a switch fabric, a command module, and a testing module.  The switch fabric provides all voice channel connections between all switches and the remote terminal and grooms the control channels. Control messages are switched into the command module, which performs any protocol translations necessary.  All commands from switches are then multiplexed and sent back to the switch fabric, which routes them to the original command channel to the remote terminal. Control messages from the remote terminal are demultiplexed, translated (if necessary) and sent to the switch fabric for delivery to the appropriate switch. Testing of lines is also provided to all competitive service providers.

Title: Apparatus and method for ultrasonic spectroscopy testing of materials
Inventor: TUCKER JAMES R
IPC: G01N29/44
Filed: 1995-05-09
Abstract: An apparatus and method for performing ultrasonic spectroscopy provides for rapid evaluation of test materials with good amplitude, balanced response at all test frequencies. A swept frequency signal is generated which is applied to a transmit transducer (11) coupled to a test part (10). A receive transducer (12) provides a detected signal that is fully digitized for real-time or post signal processing. The created swept frequency signal can be equalized from data obtained from direct coupling between transmit and receive transducers. The resultant data is analyzed for amplitude and/or phase information as a function of frequency and can be used to analyze filter characteristics, identify resonances, characterize material signatures, and many other applications.

Title: Infusion pump with tube spike holder
Inventor: HERSKOWITZ GLENN
IPC: A61M5/155
Filed: 1995-10-16
Abstract: An infusion pump (10) for infusing solutions from IV bags through tubing to patients. The pump (10) comprises a compartmented housing which receives an IV bag (24) in a solution-dispensing position. The bag (24) is placed over a bladder (26) within the compartment (18, 20), and the bladder (26) is expanded by a pressurized fluid to apply a pushing force against the bag (24) which collapses to infuse solution through the tubing. A pump (28) in the housing pumps a fluid such as air into the bladder (26) under influence of a control circuit (34). A pressure sensor (36) indirectly senses pressure of fluid in the bladder through a push of pad (38) which contacts the bladder wall. A control circuit (34) generates a pressure signal responsive to movement of the pressure pad (38) for operating a valve (30) which directs fluid between the pump and bladder. A dispensing spike (68) is provided for interconnecting a dispensing port (64) of the bag in fluid communication with the tubing.

Abstract: Une méthode pour réaliser la revascularisation transmyocardique comprend les étapes suivantes : pratiquer une incision dans une partie externe du tissu cardiaque d'un patient et percer un canal dans le myocarde du patient à travers l'incision en faisant progresser un dispositif servant à percer un canal dans le myocarde au-delà de la profondeur de l'incision pour enlever du tissu myocardique sans enlever la totalité de la partie externe du tissu cardiaque coïncidant avec le canal. En conséquence, le tissu restant de la partie externe agit comme un bouchon pour réduire le saignement en provenance du canal après le retrait du dispositif servant à percer un canal. Le bouchon peut se présenter sous forme de lambeau annulaire de tissu myocardique/épicardique. Le dispositif servant à percer un canal utilisé pour pratiquer le canal accompagnant la méthode peut être soit un dispositif de carottage mécanique soit un dispositif au laser.
