  • Patent number: 6734287
    Abstract: Disclosed are binding proteins that specifically bind to an isolated and purified peptide comprising a leucine positioned two peptide bonds away from a tyrosine-arginine pair. Other binding proteins of the invention include those that specifically bind to an isolated and purified peptide with the sequence cysteine-blank-blank-proline-histidine-blank-blank-blank-cysteine (SEQ ID NO:6) or cysteine-blank-proline-histidine-blank-proline-blank-blank-cysteine (SEQ ID NO:9).

  • Patent number: 6537781
    Abstract: The present invention provides the nucleotide and amino acid sequences of canine IL-5. It also sets forth a recombinant DNA molecule, and conservative variants thereof, comprising the DNA sequence of canine IL-5, and recombinant vectors such as expression vectors, comprising a DNA sequence encoding canine IL-5. Further, the invention sets forth polypeptides produced using a recombinant expression vector containing a canine IL-5 sequence. Also disclosed are compositions comprising a nucleotide sequence that is antisense to a DNA sequence encoding a component of canine IL-5, wherein the component can be the full canine IL-5 protein.

  • Patent number: 5236228
    Abstract: An annular disk-shaped pipe adaptor permits a small water meter to be connected to a large diameter water pipe. The adaptor has a first side which is adapted to attach to the large flange of the large diameter pipe. The opposing side of the adaptor includes a plurality of outwardly extending threaded studs which are adapted for extending through holes provided in the flange of the inlet pipe of the water meter. A tapered central aperture gradually reduces the flow of water as it passes from the large diameter pipe to the water meter.

  • Patent number: 4030840
    Abstract: A waveform sampler, for cooperation with a conventional sampling oscilloscope, has, as part of a bridge circuit, two Gallium Arsenide photoconductors mounted on a 50 ohm stripline. One GaAs photoconductor, the sampling photoconductor, is illuminated. The other GaAs photoconductor remains dark and functions as a common mode compensating photoconductor. To sample an unknown electrical waveform traversing the stripline the electrical wave is optically strobed by illuminating the sampling GaAs photoconductor with pulses of light from a laser. To sample an unknown optical waveform the optical wave is focused on the sampling GaAs photoconductor and an electrical strobe signal is sent through the stripline. Outputs from each of the photoconductors are amplified in high input impedance FET amplifiers and after electrical compensation they are passed to a conventional difference amplifier. The difference output is further amplified and fed to a conventional sampling oscilloscope.
