Filed: 1998-07-03
Granted: 2005-12-20
Abstract: Disclosed is an improved assay for the determination of total protein in an aqueous test fluid such as urine. The assay involves combining the test fluid with a molybdate or tungstate salt and a dye which forms a complex with molybdate or tungstate ion at a pH of 1.0 to 3.0 to shift the absorption band of the complex in the presence of protein. There is introduced into the assay a substituted phenolsulfonephthalein dye having a pKa which enables it to operate at a pH of from about 1.0 to 3.0 and whose affinity for protein is such that it will provide a detectable response only in the presence of greater than 50 mg/dL of protein to increase the scope of the assay.

Abstract: A fireplace has a glass window and a mesh screen. The fireplace has a viewing opening into a firebox generally surrounded by an enclosure except about the viewing opening. The glass window encloses the opening of the firebox. The mesh screen extends over the glass window opposite the firebox. The mesh window is constructed of a woven wire mesh. The woven wire mesh reduces the amount of incident light to the glass window from outside the firebox, thus reducing the amount of glare perceived from the viewing area. The mesh screen also provides a relatively cool protective barrier in front of the glass window which has the potential of becoming too hot to touch. Various shapes of the mesh window are possible including a bay window-like shape. The screen assembly may be used with various types of fireplaces including direct vent and room air vented gas fireplaces.

Abstract: An image is reproduced and transferred onto a substrate by (a) providing a positive electrode having a continuous passivated surface moving at substantially constant speed along a predetermined path, said passivated surface defining a positive electrode active surface; (b) forming on the positive electrode active surface a plurality of dots of colored, coagulated colloid representative of a desired image, by electrocoagulation of an electrolytically coagulable colloid present in an electrocoagulation printing ink containing a coloring agent; and (c) bringing a substrate into contact with the dots of colored, coagulated colloid to cause transfer of the colored, coagulated colloid from the positive electrode active surface onto the substrate and thereby imprint the substrate with the image. Step (b) is carried out by (i) providing a series of negative electrodes each having a surface covered with a passive oxide film, the negative electrodes being electrically insulated from one another and arranged in rectilinear alignment so that the surfaces thereof define a plurality of corresponding negative electrode active surfaces disposed in a plane spaced from the positive electrode active surface by a constant predetermined gap, the negative electrodes being spaced from one another by a distance smaller than the electrode gap; (ii) coating the positive electrode active surface with an olefinic substance to form on the surface micro-droplets of olefinic substance; (iii) filling the electrode gaps with the electrocoagulation printing ink; (iv) applying to the negative electrodes a bias voltage ranging from -1.5 to -2.5 volts; (v) applying to selected ones of the negative electrodes a trigger voltage sufficient to energize same and cause point-by-point selective coagulation and adherence of the colloid onto the olefin-coated positive electrode active surface opposite the electrode active surfaces of the energized electrodes while the positive electrode active surface is moving, thereby forming the dots of colored coagulated colloid; and (vi) removing any remaining non-coagulated colloid from the positive electrode active surface. The invention enables one to obtain an image resolution as high as 400 lines per inch, or more.
