Title: Hypersensitive response induced resistance in plants by seed treatment
Inventor: BEER STEVEN V
IPC: A01N63/50
Filed: 1997-12-04
Abstract: The present invention relates to a method of imparting pathogen resistance to plants. This involves applying a hypersensitive response elicitor polypeptide or protein in a non-infectious form to a plant seed under conditions where the polypeptide or protein contacts cells of the plant seed. The present invention is also directed to a pathogen resistance imparting plant seed. Alternatively, transgenic plant seeds containing a DNA molecule encoding a hypersensitive response elicitor polypeptide or protein can be planted in soil and a plant can be propagated from the planted seed under conditions effective to impart pathogen resistance to the plant.

Title: Unplanar non-axisymmetric inserts
Inventor: SOUTHLAND STEPHEN G
IPC: E21B10/567
Filed: 1999-07-05
Abstract: Cutting elements for incorporation in a drill bit are provided having a body having an end face interfacing with an ultra hard material cutting layer. A main depression having a nonplanar surface is formed on the substrate and extending to the edge of the substrate subjected to the highest impact loads during drilling. This edge is immediately below the edge of the cutting layer which makes direct contact with the earth formations during drilling.  The main depression is formed by forming a plurality of secondary depressions or steps such that depth of the main depression decreases in a radial direction towards the edge of the cutting element. An ultra hard material layer is bonded to the end face of the cutting element body such that the cutting layer is the thickest over the main depression. Consequently, the cutting layer edge making contact with the earth formations during drilling has an increased thickness.

Title: Method for separating bi-213 from a solution of radionuclides
Inventor: BRAY LANE A
IPC: B01D15/04
Filed: 1998-01-28
Abstract: A method for separating 213Bi from a solution of radionuclides wherein the solution contains a concentration of the chloride ions and hydrogen ions adjusted to allow the formation of a chloride complex. The solution is then brought into contact with an anion exchange resin, whereupon 213Bi is absorbed from the solution and adhered onto the anion exchange resin in the chloride complex. Other non-absorbing radionuclides such as 225Ra, 225Ac, and 221Fr, along with HCl are removed from the anion exchange resin with a scrub solution. The 213Bi is removed from the anion exchange resin by washing the anion exchange resin with a stripping solution free of chloride ions and with a reduced hydrogen ion concentration which breaks the chloride anionic complex, releasing the 213Bi as a cation. In a preferred embodiment of the present invention, the anion exchange resin is provided as a thin membrane, allowing for extremely rapid adherence and stripping of the 213Bi. A preferred stripping solution for purification of 213Bi for use in medical applications includes sodium acetate, pH 5.5. A protein conjugated with bifunctional chelating agents in vivo with the Na0Ac, to receive the 213Bi as it is being released from the anion exchange resin.

Title: Leak detection system for liquid processing device
Inventor: LAUMAN BRIAN C
IPC: G01M3/18
Filed: 1998-02-27
Abstract: A leak sensor system for use in liquid processing equipment is disclosed. Liquid is detected by a sensing resistor whose impedance decreases dramatically in the presence of liquid. The effect of this impedance drop on the output voltage of the sensor indicates a wet or moist state which may indicate leakage from the liquid processing. A terminal resistor is in the circuit beyond the sensing resistor to provide a warning indicator when the sensing resistor is damaged or disconnected. The leak sensor system is particularly useful in centrifuge equipment, e.g., for the processing of blood.

Inventor: MCCAUGHAN DANIEL VINCENT
IPC: H04L12/70
Filed: 1998-04-17
Abstract: A connectionless communications network includes a number of low earth orbit (LEO) satellite nodes. Motion of the satellites constantly changes the topology of the network. A virtual model of the network having fixed virtual nodes, is maintained in a connection control system. This virtual model is used to control the route that traffic will take through the real network. As topology changes happen in the network then the virtual nodes of the model become embodied by different real nodes and communicate their virtual identity to connected nodes. Routing of the traffic is performed with reference to the virtual network so that routing follows the current embodiment of the virtual network.

Title: Nuclear magnetic resonance measurements in well logging using an optimized rephasing pulse sequence
Inventor: SLADE ROBERT ANDREW
IPC: G01V3/32
Filed: 2000-04-19
Abstract: A pulsed NMR tool has a magnet arrangement that is used to generate a static magnetic field having a substantially uniform field strength in a region of the formation surrounding the borehole. An RF coil is used to produce pulsed RF  fields substantially orthogonal to the static field in the region of examination. The nuclear spins in the formation align themselves along the externally applied static magnetic field. A pulsed RF field is applied to tip the spins into the transverse plane, resulting in a precession of the spins. The tipping pulse is followed by a series of refocusing pulses and the resulting series of pulse echoes is detected. The timing and duration of RF pulses are altered from conventional CPMG to maximize signal and minimize RF power consumption. An additional forced recovery pulse at the end of an echo train may be used to speed up the acquisition and/or provide a signal for cancelling the ringing artefact.

Title: System and method for maintaining timing synchronization in a digital video network
Inventor: LAWRENCE PETER H
IPC: H04H20/82
Filed: 1998-11-04
Abstract: A novel system and method for maintaining timing synchronization in a digital video network, in conjunction with a digital video and data delivery system, makes possible the delivery of digital video content, bi-directional data services, such as Internet data (14), and plain old telephone service (POTS) to an end user over a communications channel. The channel is typically the copper wire pair that extends between a telephone company central office (100) and a residential premises (1300), but may be any communication medium that supports the communication of compressed digital video, bi-directional data, such as Internet data, and POTS, and indeed, may be a wireless connection. The digital video and data delivery system capitalizes on a bus, or broadcast backplane, created by circuitry contained within the central office. The broadcast backplane enables a plurality of video program data to be available to each end user, and a1lows a plurality of end users access to a plurality of video programming content without the necessity of delivering the entire program content to each user. The digital video and data delivery system employs novel architecture to synchronize the timing of the digital video signal to ensure that the digital video program received is of high quality and that it also complies with the MPEG-2 standard.
