摘要:
A double barrel sprayer for applying a diluted product such as a diluted cleaning solution to a surface for cleaning thereof and rinsing the diluted product from the surface by spraying a water-only rinse onto the surface. The sprayer can include a force-fitted orifice plate with a plurality of holes for adjusting the water/product mixing ratio. To provide different spray patterns for the water-rinse or diluted product, the sprayer can include a shroud having suitably shaped exit holes. The sprayer includes separate flow paths for the water-only rinse and the diluted product. The flow path for the diluted product includes a mixing chamber in which concentrated product is siphoned from a container and mixed with water supplied by a garden hose. Prior to mixing with the water, the concentrated product passes through an orifice plate having a plurality of holes to provide a substantially constant water/product ratio over a wide range of water pressures. The sprayer includes a removable cover which includes a pair of outlets suitably sized and shaped to obtain desirable spray patterns for the water-only rinse and the diluted product sprayed from the sprayer. A rotatable valve allows selective application of water or diluted product.

A system and method are provided for synchronizing threads in a divergent region of code within a multi-threaded parallel processing system. The method includes, prior to any thread entering a divergent region, generating a count that represents a number of threads that will enter the divergent region. The method also includes using the count within the divergent region to synchronize the threads in the divergent region.

A metallization on a semiconductor substrate is disclosed in the form of a laminate comprising a plurality of layers of a “conducting” metallization for providing electrical conductivity, interspersed with a plurality of layers of another metallization. By providing many layers the thickness of each individual layer can be reduced. Reduction in thickness of each layer leads to a reduction in grain size and a consequent reduction in creep over the lifetime of a device.

The present invention is directed to a novel organic peanut butter formulation and method for production. The peanut butter includes an organic palm oil stabilizing agent that reduces or prevents separation of oils from the peanut butter during storage. Peanut butter incorporating the palm oil, methods for manufacturing the peanut butter, and foods incorporating the peanut butter are also disclosed.

The present invention is based, at least in part, on the generation of cells, cell lines and non-human mammals that contain a synthetic conditional allele of the Dicer1 gene. Many of the constructs, methods, animals and cells of the invention feature recombinase recognition sites (in certain embodiments, loxP sites) positioned on either flank of a sequence that comprises exons 14, 15 and 16 of the Dicer1 gene (in certain embodiments, the mouse Dicer1 gene). Through readily manipulable introduction, administration, or expression of a recombinase (in certain aspects of the invention, the Cre recombinase of bacteriophage P1), exons 14 through 16 of Dicer1 may be directedly excised, producing a functional knockout of Dicer1 in cells containing these recombinase-induced alleles of the invention.
摘要:
Aspects of this invention include a downhole tool and method for making a physical caliper measurement of a subterranean borehole. The tool is configured to make the physical borehole caliper measurement only when the measured pressure in each of three or more outwardly extendable blades is greater than a predetermined threshold pressure. Blade positions are measured and the borehole caliper calculated only when the pressure in each of the blades exceeds the threshold. Exemplary embodiments of the invention enable physical caliper measurements to be made with increased accuracy with each of the blades making firm contact with the borehole wall. Methods in accordance with the invention are especially well suited for use in directional drilling applications in that they tend to enable accurate caliper measurements to be made without repositioning the steering tool in the borehole.

Aspects of this invention include a steering tool having a controller configured to provide closed-loop control of hydraulic fluid pressure. In one exemplary embodiment, closed-loop control of a system (reservoir) pressure may be provided. In another embodiment, closed-loop control of a blade pressure may be provided while the blade remains substantially locked at a predetermined position. Other exemplary embodiments may incorporate rule-based-intelligence such that pressure control thresholds may be determined based on various measured and/or predetermined downhole parameters. The invention tends to reduce the friction (drag) between the blades and the borehole wall and thereby also tends to improve drilling rates. Moreover, the invention also tends to improve the service life and reliability of downhole steering tools.
