Abstract: A water-base fluid for use in drilling wells and other drilling operation includes a shale which swells in the presence of water. The fluid preferably includes: an aqueous based continuous phase, and a shale hydration inhibition agent having the formula:
H2N—R—{OR′}x—Y
in which R and R′ are alkylene groups having 1 to 6 carbon atoms and x is a value from about 1 to about 25. The Y group should be an amine or alkoxy group, preferably a primary amine or a methoxy group. The shale hydration inhibition agent should be present in sufficient concentration to reduce the swelling of the shale. The fluid may be used for formulating drilling fluids such as invert emulsion drilling muds or clear brine drilling fluids. The fluid may also be used in the slurrification and disposal of drill cuttings that contain water swellable clays or shales.

Abstract: This invention relates to an isolated nucleic acid fragment encoding a protein involved in phenylpropanoid metabolism. The invention also relates to the construction of a chimeric gene encoding all or a portion of the protein involved in phenylpropanoid metabolism, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the protein involved in phenylpropanoid metabolism in a transformed host cell.
Abstract: A process for producing a polyester that comprises 1 to 90 wt. % poly(alkylene ether) glycol. The process comprises the step of copolymerizing (i) a preformed polyester polymer having an inherent viscosity of at least 0.4 dL/g, (ii) a poly(alkylene ether) glycol, and (iii) a dicarboxylic acid or anhydride, to obtain a polyester comprising 1 to 90 wt. % poly(alkylene ether glycol).
Abstract: A flexible ballistic resistant article is disclosed that includes a plurality of layers of fabric having an areal density of 2 to 10 kg/m2, wherein at least two of the layers of fabric are loosely woven. The loosely woven fabric layers include fabric woven with a fabric tightness factor of 0.3 to 0.6 and are made using continuous filament yarns with a linear density of at least 200 dtex, a tenacity of at least 10 grams per dtex and a tensile modulus of at least 150 grams per dtex. Adjacent loosely woven fabric layers are joined together by means for securing the layers to restrict the movement of the loosely woven fabric layers relative to one another.
Abstract: The invention relates to a single- or multilayer plastic sheeting for covering products, particularly ensiled agricultural products, or similar, like chopped silage. According to the invention, in order to prevent the fermentation of the ensiled material or to limit it to a lactic fermentation caused by anaerobic microorganisms, the cover sheeting or at least one layer of said sheet is made of an insulating plastic airtight material.

Abstract: A multi-tier, master-slave control network has a matrix architecture for facilitating monitoring, command and control of the mid- and lower-tiers of the control network. A supervisory network is connected to a hierarchical master-slave control network, and includes a set of supervisory nodes connected to various different buses of the main hierarchical master-slave control network. In one embodiment, the supervisory network comprises a multi-master data bus, and each of the supervisory nodes can control and communicate across the supervisory data bus in a manner similar to a local area networks such as an Ethernet. In another embodiment, the supervisory network is a master-slave network, with a supervisory master node controlling a set of supervisory slave nodes, each of which connects to one of the lower-tier buses. The matrix architecture created by the addition of the supervisory network allows convenient monitoring of the lower-tier buses by the first-tier master node.

Abstract: The present invention is related to a tap water temperature measuring device includes setting up a thermoscope IC board inside device tube. The thermoscope IC board is formed by circuit activation probe, which combines activation probe and temperature probe. While the water pass by the probes, it will activated the switch which creates circuit function thermoscope IC board. The temperature probe detects the water temperature from the tap and passes the reading to the device tube constantly. The LCD and the warning indicator lights are located on the side of the device tube for users convenience (the warning light enable one to tell the instant temperature). Therefore, knowing and controlling the water temperature from the tap at all time, which prevents congelatioin and ambustion, will protect the users.

Abstract: There is provided a vibrator which is integrally coupled to a rotating shaft of a motor. A groove portion in which the rotating shaft is fitted is formed in an eccentric load portion, and side walls extending from the eccentric load portion and forming both side edge portions of the groove portion are provided. A portion of a tip portion end surface of each side wall, except at an outer peripheral portion of the side wall and at a side of the groove portion, is caulked from an opening side of the groove portion toward a bottom side thereof, so that the vibrator is integrally coupled to the rotating shaft.
Abstract: The present invention provides for an etch and mar resistant low VOC clear coating composition most suitable for use as a top clear coat in multi-layered OEM or refinish automative coatings. The coating composition includes isocyanate, silane and melamine components. The isocyanate component includes an aliphatic polyisocyanate. The composition may be formulated as a two-pack or one-pack coating composition, wherein the isocyanante functionalities are blocked with a blocker such as a mono-alcohol.

Abstract: An aqueous-based inoculant composition in liquid form for leguminous seeds that produces an immediate nodule formation and an increased nitrogen fixation, containing microorganisms of the Rhizobium or Bradyrhizobium genus, a molybdenum compound selected from alkali metal molybdates and a compound that neutralizes the seed exudates, which are toxic for the bacteria, selected from polymers of compounds presenting an amide, amine or imine moiety. The inoculant composition remains stable at room temperature, keeping the number of viable bacteria over long periods of time and ready to be used.
Abstract: The global effect on genes under different environmental conditions can be determined by a comprehensive gene expression profile. The present invention provides a method to monitor the changes in comprehensive cellular gene expression levels at single length resolution by using a high-density microarray prepared with a comprehensive collection of ORFs of a genome. Under different environmental conditions, directly and indirectly affected genes can be detected as the gene expression levels are induced or repressed in comparison to the control.
