摘要:
Coloring compositions comprising peptide-based dispersants and/or binders are provided. The compositions are particularly useful for the coloring or dyeing of substrates such as paper and textile fabrics. The peptide-based dispersant and/or binder compositions are distinguished by the presence of at least one positively charged terminal amino acid on the peptide portion of the composition which enhances binding to the substrate.

Apparatus and method for mixing a fluid dispersion disposed in a container having either a cylindrical or a square shape. The apparatus includes a holding structure having a retaining structure connected to a base. The retaining structure prevents lateral movement of the container both when the container has a cylindrical shape and when the container has a generally square shape with a width substantially equal to the diameter of the cylindrical shape. The apparatus rotates the container about at least one axis.

An assured flow conduit has an inner conduit having an inner diameter sized to accommodate a flow of warm fluid and an outer diameter. The inner conduit is formed from a material having a low hydrogen content. An outer conduit encloses the inner conduit and has an inner diameter larger than the outer diameter of the inner conduit and defines a space there between. An insulating sleeve is interposed between the inner conduit and the outer conduit and within the space, wherein the sleeve is formed from an aerogel.

Percussive signal transmission tubes, of contrasting color, are joined along adjacent longitudinally extending portions by an adhesive bead of polymeric material. The tubes can be separated in the field and are provided on spools without any sheath. A small diameter (0.10 inch) tube can be used to reduce the size of the spool, or increase the length of tubing wound on the spool. An apparatus for assembling the product is also disclosed.

A system for providing purified drinking water for populations and persons having minimal access to modern water purification systems and therefore rely on water sources which contain microorganisms known to cause illness and death to large segments of such populations. Membranes are known which are pervious to water and impervious to the contaminants in such drinking water. The invention provides for gravity flow passage of water from the dirty (contaminated) water containment area to a clean (purified) water containment area and a filter including such a membrane whereby the flow of water has to penetrate through the membrane and in the process filters out the illness-producing microorganisms. The invention enables the use of commonly available jugs or jars requiring only a gravity flow passage between the jugs or jars and the filter contained in the passage.

A system and method is provided for vectorizing misaligned references in compiled code for SIMD architectures that support only aligned loads and stores. In the framework presented herein, a loop is first simdized as if the memory unit imposes no alignment constraints. The compiler then inserts data reorganization operations to satisfy the actual alignment requirement of the hardware. Finally, the code generation algorithm generates SIMD codes based on the data reorganization graph, addressing realistic issues such as runtime alignments, unknown loop bounds, residue iteration counts, and multiple statements with arbitrary alignment combinations. Beyond generating a valid simdization, a preferred embodiment further improves the quality of the generated codes. Four stream-shift placement policies are disclosed, which minimize the number of data reorganization generated by the alignment handling.

Peptides have been identified that bind with high affinity to body surfaces, such as, hair, skin, nails, teeth, gums, corneal tissue, and oral cavity surfaces. Peptide-based body surface reagents formed by coupling a body surface binding peptide to a benefit agent are described. The peptide-based body surface reagents include peptide-based hair conditioners, hair colorants, skin conditioners, skin colorants, nail colorants, and oral care reagents. The peptide-based hair conditioners and hair colorants are comprised of a hair-binding peptide coupled to a hair conditioning agent or a coloring agent, respectively. The peptide-based skin conditioners and skin colorants are comprised of a skin-binding peptide coupled to a skin conditioning agent or a colorant, respectively. The peptide-based nail colorants are comprised of a nail-binding peptide coupled to a coloring agent. The peptide-based oral care reagents are comprised of an oral cavity surface-binding peptide coupled to an oral care benefit agent. In all these compositions, the peptide may be directly coupled to the active agent or the coupling may be via a spacer. Personal care compositions containing these peptide-based body surface reagents are also described.

A lens is formed out of semiconductor material. The semiconductor produces light which is coupled to the lens. The lens focuses the light and also minimizes refractive reflection. The lens is formed by a graded aluminum alloy, which is oxidized in a lateral direction. The oxidation changes the effective shape of the device according to the grading.
