Abstract: A method and apparatus for fracturing and propping a fracture interval in which a workstring is lowered into the wellbore and a fracturing slurry comprised of a fracturing fluid and proppants is flowed down the workstring to a downhole slurry splitter which separates a portion of the fracturing fluid from the slurry and delivers it to the bottom of the fracture interval to initiate and propagate a fracture in the interval. The remaining slurry including the proppants is at the same time delivered to the top of the interval to prop the fracture as it is being formed. Alternate flowpath(s) deliver fracturing fluid and/or slurry to different levels within the interval to by-pass any sand bridges which may be formed during the fracturing operation.

Title: System and method for regulating delivered radiation in a radiation-emitting device
Inventor: HUGHES JOHN H
IPC: A61N5/10
Filed: 1996-07-18
Granted: 2007-04-10
Abstract: In a radiation emitting device, particularly in a radiation treatment device, the actual radiation delivered to an object via a radiation beam is adjusted dependent on the dimensions of an opening in a plate arrangement provided between a radiation source and an object so that the radiation output has a constant output factor over an irradiation field, regardless of the size of the opening. The output factor is defined as the ratio of the radiation output in air with a scatterer (such as shielding plates) in the beam path to the radiation output without the scatterer for a reference field.

Abstract: A cooling bed plate transfer grid insert which is height adjustable independently of its mounting to the grid. The insert has an outer frame which is clampable to the grid and an inner frame supporting a roller'and which is clampable to the outer frame and height adjustable'relative to the outer frame so that the mounting of the outer frame to the grid need not be disturbed when adjusting the height of the roller or when replacing the inner frame and roller assembly.for repair of the insert. The inner frame is thus easily and inexpensively replaceable without the necessity of replacing the outer frame. The replaceable inner frame includes stationary bearings for the rotating roller shaft to provide improvement in wear life of perhaps about 200 per cent. Springs are provided to.allow the roller to flexibly move downwardly under load of plates being moved thereover so that each of the rollers underlying a plate bears its share of the load, but the rollers are biased to the desired unloaded height. A ramp is provided on the inner frame for deflecting the plates being transferred onto the roller and thereby eliminating or reducing "catch points" which may cause thin plates to bend. The end portions of the inserts have mating tongues and grooves allowing successive end-to-end placement of the inserts.

Abstract: A plurality of embodiments for a flexible probe used to provide photodynamic therapy (PDT) and to effect other medical procedures at an internal treatment site inside a patient's body. Each of the embodiments of the flexible probe (100, 108, 130, 158, 182, 190, 220, 280, 370, 390, 440, 460, 520) includes a flexible substrate (102, 184, 196, 222, 250, 282, 412, 462, 482, 502, 522) on which are disposed conductive traces (414, 466, 468, 488, 490, 504, 506, 524, 526) electrically connected to leads through which electrical current and signals are conveyed. A plurality of light sources (104, 192, 256, 286, 418, 436, 470, 492, 508, 542) or other micro-electronic circuits are connected to the conductive traces and mounted on the flexible substrate. Each of the embodiments of the flexible probes is enclosed within a transparent, biocompatible polymer envelope (106, 110, 464, 522). Due to the characteristic elastic properties of the flexible substrate, the flexible probe can readily be bent, folded or rolled while being disposed at the internal treatment site.  Thus, for example, a curved surgical needle (650) can be used to implant a flexible probe at the treatment site by drawing the flexible probe through tissue along a curved path to a desired position; one or more disk-shaped buttons (660, 670) that are attached to the ends of the flexible probe can be used to secure the flexible probe so that it does not move from the desired position.
