  • Patent number: 6390625
    Abstract: A focusing mechanism for an optical instrument includes an eyepiece having at least one lens element retained within an eyepiece housing, a stationary carrier for retaining the eyepiece, and a rotatable thumb wheel. A pair of levers operatively connect the eyepiece housing with the rotatable thumb wheel, the thumb wheel including corresponding pairs of cam channels on either side for receiving one end of a corresponding lever, the remaining end of each lever engaging the eyepiece housing, wherein rotational movement of the thumb wheel produces axial movement of the eyepiece relative to said carrier.

  • Patent number: 6370405
    Abstract: A multifilamentary superconductor composite having a high fill factor is formed from a plurality of stacked monofilament precursor elements, each of which includes a low density superconductor precursor monofilament. The precursor elements all have substantially the same dimensions and characteristics, and are stacked in a rectilinear configuration and consolidated to provide a multifilamentary precursor composite. The composite is thereafter thermomechanically processed to provide a superconductor composite in which each monofilament is less than about 50 microns thick.

  • Patent number: 6340756
    Abstract: wherein Z1 is hydrogen or an amino-protecting group selected from the group consisting of acyl of the formula R—C(O)—, wherein R is alkyl of 1-6 carbon atoms; trityl, optionally substituted with methoxy; and N-(9-fluorenylmethoxycarbonyl); Y1 is halo, aralkyloxy or acyloxy, wherein acyl is as defined above; and Y2 is aralkyloxy. These intermediates are useful in a novel process for preparing the mono-L-valine ester of 2-(2-amino-1,6-dihydro-6-oxo-purin-9-yl) methoxy-1,3-propanediol (ganciclovir). The mono-L-valine ester of ganciclovir and its pharmaceutically acceptable salts are of value as antiviral agents with improved absorption.

  • Publication number: 20020004460
    Abstract: The invention features high performing composite superconducting oxide articles that can be produced from OPIT precursors substantially without poisoning the superconductor. In general, the superconducting oxide is substantially surrounded by a matrix material. The matrix material contains a first constraining material including a noble metal and a second metal. The second metal is a relatively reducing metal which lowers the overall oxygen activity of the matrix material and the article at a precursor process point prior to oxidation of the second metal. The second metal is substantially converted to a metal oxide dispersed in the matrix during or prior to a first phase conversion heat treatment but after formation of the composite, creating an ODS matrix.

  • Patent number: 6331113
    Abstract: A patient's dental prosthesis (e.g., a prosthesis tooth, crown, veneer, or bridge) is made by acquiring an image of the patient's teeth that contains black and white normalization references. These references are black and white porcelain, for example, that allow software of the invention to determine absolute black and absolute white within the color image. The acquired color image is then normalized in accordance with the normalization references, which corrects the image for variations in lighting conditions and image source. The normalized image is then standardized by matching the pixels of the normalized image to selected shade standards. The dental prosthesis can then be manufactured by a lab technician by referring to the standardized image. The tooth shade analysis and matching system is also applicable to direct restorations of natural teeth, such as repair of chipped or broken teeth. Methods of whitening teeth are also disclosed.

  • Patent number: 6321472
    Abstract: An iron includes a soleplate and a water tank connected to the soleplate for supplying steam to the soleplate. The water tank includes a cavity for holding water, a fill opening for filling the cavity with water, and a guide arrangement associated with the fill opening. A handle is connected with the water tank. A rear cover is connected to a rear end of the water tank, the rear cover having a rear plate in covering relation to a rear portion of the iron, and the rear plate including an arrangement for stabilizing the iron in an upright position on a soft surface. The arrangement includes a recess in an outer surface of the rear plate, and at least one non-slip foot extending from the outer surface of the rear plate. A fill door is slidably mounted on the guide arrangement between a closed position in covering relation to the fill opening and an open position to permit filling of the cavity with water through the fill opening.

  • Patent number: 6319494
    Abstract: Chimeric proteins and DNA encoding chimeric proteins are provided, where the chimeric proteins are characterized by an extracellular domain capable of binding to a ligand in a non-MHC restricted manner, a transmembrane domain and a cytoplasmic domain capable of activating a signaling pathway. The extracellular domain and cytoplasmic domain are not naturally found together. Binding of ligand to the extracellular domain results in transduction of a signal and activation of a signaling pathway in the cell, whereby the cell may be induced to carry out various functions relating to the signalling pathway. A wide variety of extracellular domains may be employed as receptors, where such domains may be naturally occurring or synthetic. The chimeric DNA may be used to modify lymphocytes as well as hematopoietic stem cells as precursors to a number of important cell types.
