Title: Novel butyrolactones with antifungal activity
Inventor: PAULITZ TIMOTHY C
IPC: C07D307/60
Filed: 1998-09-30
Abstract: The bacterium Pseudomonas aureofaciens 63-28 is antagonistic to several plant pathogenic fungi, including Pythium spp. The bacterium produced at least four antifungal metabolites active against Pythium ultimum and Phytophthora cryptogea when tested in culture for antifungal activity. Three of these compounds were identified as the novel butyrolactones: 3-(1-hexenyl)-5-hydroxymethyl-2,5(H)furanone (alternate nomenclature: (Z)-4-hydroxymethyl-2-(1-hexenyl)-2-butenolide), 3-(1-hexenyl)-5-hydroxy-5-methyl-2,5(H)furanone (alternate nomenclature: (Z)-4-hydroxy-4-methyl-2-(1-hexenyl)-2-butenolide) and 3-(1-hexenyl)-5-methyl-2,5(H)furanone, respectively, by using NMR and GC-MS. All compounds were different from other antibiotics produced by Pseudomonas spp., including pyoluteorin, pyrrolnitrin, and 2,4-diacetylphloroglucinol, as determined by HPLC. This is the first report of butyrolactones with antifungal activity produced by a saprophytic Pseudomonas spp.

Abstract: Methods and systems for routing information in an integrated global communications network comprising a signalling system interconnecting a source router, a plurality of intermediate routers, a destination router and a routing processor for routing the multimedia information. The source router receives the information including the routing requirements associated with the information and transmits a routing query signal to the routing processor. The routing processor evaluates the routing requirements, determines which routers and communication paths are capable and available to route the information, evaluates the statistical availability of such routers and selects an optimal routing path comprising select ones of the available routers and communication paths.

Title: Flash tube reflector with arc guide
Inventor: THOMAS BRADLEY SCOTT
IPC: F21V7/00
Filed: 1999-02-26
Abstract: A combined reflector and arc guide for use with a xenon flash tube comprises a reflector structure having a reflecting surface that is adapted to be placed in a predetermined orientation with respect to the flash tube. An electrically conductive arc guide is carried by, and is preferably integral with, the reflector structure for controlling the arc in the flash tube. The arc guide comprises an elongated ridge that projects outwardly from the reflecting surface of the reflector structure, and extends in a direction substantially parallel to the longitudinal axis of the flash tube. An electrical terminal is carried by the reflector structure and has an electrical connection to the arc guide for allowing an electrical potential to be applied to the arc guide. The reflector structure is preferably made of an electrically conductive plastic material, thereby providing continuity between the electrical terminal and the arc guide without the need for a separate conductor. An area of modified reflectivity, preferably in the form of a plurality of grooves, may be provided in the reflective surface of the reflector structure to spread out the intensity peak of the flash tube. The disclosed reflector is simple and inexpensive to manufacture, and is suited for use in automated hematology systems in which a pulse of light from the flash tube causes dyed blood cell layers in a capillary tube to fluoresce so that a complete blood count can be obtained by optical imaging techniques while the blood sample is being rotated in a centrifuge.

Title: Modular mobile drilling system and method of use
Inventor: MOCHIZUKI DAVID A
IPC: E21B15/00
Filed: 1999-07-28
Abstract: A modular mobile drilling system and method of use supports land-based drilling operations on remote sites.      Plural support boxes fixedly deployed in first and second rows define a drilling zone. Plural platform support beams disposed from the first row to the second row support a platform for holding drilling equipment. An actuator associated with the platform and beams skids the support beams relative to the boxes to align the platform with predetermined positions in the drilling zone, allowing the drilling of multiple wells along the length of the support box rows. The drilling equipment can also skid laterally across the drilling platform to support drilling of multiple rows of wells in the drilling zone.      The drilling platform is supported by some but not all of the support boxes, enabling modular transportation by helicopter of support boxes to a new remote drilling site, disassembly of the drilling platform at the existing site, reassembly.of the drilling platform on the transported boxes at the new site, and then transportation of remaining boxes from the existing site to the new site to support new drilling operations. The box-on-box substructure and skiddable drilling platform enhance transportability by helicopter and assembly with minimal footprint and reduced assembly steps.

Title: Method for profiling and calibrating a digitally controllable printing machine having a permanent printing plate
Inventor: WEICHMANN ARMIN
IPC: B41C1/00
Filed: 1999-09-28
Abstract: A method for calibrating a digitally controllable printing machine having a permanent printing plate, for which image data has been created in machine-independent format in a pre-press stage. The image data is prepared for the printing process by a data processing device and is fed in adapted form to the printing machine 1. The data processing device uses a profile which corresponds precisely with the current machine condition, for the final data preparation for printing. The profile can be addressed using the correct color-space conversion for the printing machine (i.e., calibrated). For this purpose, at the time at which the data is prepared for image setting, a machine condition forecast for the time of printing is called up and, from this, together with the knowledge of the operating materials, the machine profile which most closely approaches that for the print job is determined. This profile is then used for the data preparation.
