摘要:
A multilayer silver halide color photographic element comprising a support bearing a light-sensitive silver halide emulsion layer and a non-diffusible yellow-colored magenta dye-forming masking coupler wherein the masking coupler is a 2'-hydroxy-5'-substituted-4-phenylazo-5-pyrazolone. The masking coupler has good coupling activity and desirable hues, and can be obtained in good yields by simple syntheses.

A method for the non-destructive evaluation of the integrity of wooden members, in situ, for example, embedded in the soil, employing the reflection of an acoustic wave off of the embedded end of the wooden member. The reflection is caused by the discontinuity in acoustic properties between wood and the supporting medium. The method allows the measurement, at one end of the member, of substantially the entire length of the wooden member without its removal. The acoustic wave is monitored in time and amplitude to provide indications of sound speed and attenuation, measurements which apparently are not unduly affected by coupling losses between the wooden member and its supporting matrix. These measured values may be empirically linked in an equation providing the integrity of the wooden member.

This game is designed for entertainment fun and consists of a game board, a multiple number of playing pieces shaped like musicians and their instruments, a multiple number of discs that receive flags with music note symbols, tokens, cards, and a die. The game board consists of two separate paths, one representing the life of a rock musician and the other representing the position of a record on the charts. The winner of the game is the first player to advance their disc to the number 1 space. The disc may be advanced by completing a circuit of the outer path with the token or by collecting a specified number of flags which are placed in the disk.

A check processing module (CPM) is provided for a self-service check depositing terminal. The CPM comprises a substantially U-shaped plastic guide including (i) first and second leg portions forming the substantially U-shape, (ii) a surface which forms an opening in the first leg portion, and (ii) a releasing member which is disposed on the second leg portion. The CPM further comprises a shaft assembly including (i) a plastic shaft having opposite end portions and a central portion between the opposite end portions, (ii) a number of drive rollers disposed on the central portion, (iii) a first plastic race bearing attached to one end portion of the plastic shaft and disposed in the opening of the plastic guide, and (iv) a second plastic race bearing attached to the other end portion of the plastic shaft and secured by the releasing member to the plastic guide. The releasing member is operable to secure the shaft assembly to the plastic guide during operation of the CPM, and is operable to release the shaft assembly from the plastic guide during disassembly of parts of the CPM.

A document deskewing module is provided for a self-service bunch document depositing terminal. The document deskewing module comprises a set of sensors arranged to detect when a document transported along a document transport path from a mixed bunch of documents including documents of a first type and documents of a second type which is different from the first type is deskewed, a first set of drive rollers in the form of hard drive rollers disposed along the document transport path, a first set of idler rollers moveable towards and away from the hard drive rollers, a second set of drive rollers in the form of soft drive rollers disposed along the document transport path, a second set of idler rollers moveable towards and away from the soft drive rollers, and a controller arranged to control operation of the first and second sets of idler rollers in response to a number of signals from the set of sensors such that either only the first set of idlers are interacting with the hard drive rollers or only the second set of idlers is interacting with the soft drive rollers at any one time to deskew either a document of the first type or a document of the second type which is different from the first type.

A method and apparatus for measuring the quality of live, standing timber employs deep-set spike probes angled to create a longitudinal compression wave. Alignment tools and isolation of the probes provide an improved signal, automated detection of probe separation and amplitude-independent pulse discrimination process ensure higher reliability and repeatability of the measurements, and wireless operation provides operational efficiencies.
摘要:
A method for the preparation of a succinimide copolymer by the catalytic co-polymerization of aspartic acid with a selected polyfunctional monomer in the presence of a cyclic carbonate solvent. Succinimide copolymers of relatively high weight average molecular weight and high purity can be produced in relatively high yields while employing a relatively low catalyst loading.

The present invention is directed to a method for the production of D,L-aspartic acid. The method comprises reacting an unsaturated dicarboxylic acid or anhydride, such as, maleic acid, fumaric acid, maleic anhydride, or mixtures thereof, with excess aqueous ammonia at an elevated temperature and pressure for a time sufficient to produce diammonium D,L-aspartate. The produced diammonium D,L-aspartate is then neutralized to D,L-aspartic acid. Excess unreacted ammonia and various by-products may be recycled and re-used in the method, thereby minimizing waste and reducing cost. The produced D,L-aspartic acid may be subsequently used to make polyaspartic acid.
摘要:
A localized fiber reinforcement places strong tensile strength fibers across a hypothetical split line near notches in beams to curtail split propagation caused by cross-grain tension that may otherwise significantly reduce the strength of a beam used as a spanning member. An adhesive coated patch may be applied after a notch is cut in the beam or fibers may be attached to a beam at a factory near the location of an anticipated notching.

Disclosed are methods of producing high molecular weight, soluble, crosslinked polyaspartates from crosslinked polysuccinimide. In one preferred method aspect, polysuccinimide is first reacted with an organic crosslinking agent, preferably an organic base containing at least two primary amine groups to form a crosslinked polysuccinimide. The crosslinked polysuccinimide is then hydrolyzed to crosslinked polyaspartate which is soluble in polar solvents, preferably water, alcohol and mixtures thereof. Alternative method aspects are disclosed in which soluble crosslinked polyaspartates are produced in a single reaction vessel by sequentially crosslinking polysuccinimide with the organic crosslinking agent in an aqueous reaction mixture and hydrolyzing the product to crosslinked polyaspartate.
