Silver halide 2. PATENT EXPIRED DUE TO NONPAYMENT OF MAINTENANCE FEES UNDER 37 CFR 1.362. (a) a commentary on a particular subject. To The results are shown in the Table below. Electrostatic copies should be stored at moderate temperature and relative humidity. The process has been used since the 1920's. Facsimiles should be used whenever possible, and paper artifacts should not be displayed permanently. For the color, see Silver (color). Assigned to STERLING DIAGNOSTIC IMAGING, INC. Currently the standard photographic printing process is the gelatin silver process.

Photostat prints were often poorly processed, however, so a more conservative approach to display may be required (5,000 ft-c hours [50,000 lux hours] per year with a 3-year rest between displays). Fundamentally, there is no upper concentration limit; for practical reasons (foam formation, costs), 10 g/L should not be exceeded. A silver iodobromide emulsion with crystals of 0.4 Î¼m3 average grain volume and 2 mole percent iodide content was coated on both sides of a polyethylene terephthalate support. AGFA-GEVAERT, N.V., BELGIUM, Free format text: This is a continuation of application Ser. Inkjet is also fairly common as a modern printing process for architectural layouts rendered on with computer software (e.g. Vesicular films became popular not only because of the ability to reverse the image but also because it can be handled in daylight and process using a dry thermal process. Library is the storehouse of information. ASSIGNMENT OF ASSIGNORS INTEREST;ASSIGNOR:E. I. Carbon copy text will lack the embossed quality of the directly typewritten top copy. Copybook copies contain dye- or iron-based inks which are highly light sensitive. Absorption of a few photons results in the reductive formation of one or more clusters of silver or gold atoms on the surface. Which of the following can be used to measure the research output of an individual? Image and/or text will be slightly waxy or greasy; it will appear to float on the paper surface when viewed under low magnification. Use, Smithsonian They should not be exposed to more than 5,000 ft-c hours (50,000 lux hours) per year, and they should have a 3-year rest between displays. EXAMPLE "Smith, John". These are generally more easily soluble in weakly alkaline developer solution than cationic or nonionic wetting agents. If the sheet bears more than one ink color and is opaque, it is likely the original top copy and thus not technically a carbon copy. ISO. Rhodes, B.J. 2. English-German reprography dictionary. These layouts are large-scale line vector graphics that are often printed on paper but can sometimes be printed on either polyester film or vellum paper. 3,754,924 discloses the preparation of photographic silver halide recording elements by coating flexible supports with light-sensitive silver halide emulsions and outer coatings containing nonionic fluorinated surfactants. (b) Have clear indicator of effect i.e. Nadeau, L. (1994). Electrophotographic. Inkjet images are composed of very tiny cyan, magenta, yellow, and black dots in any number of patterns. Contact with polyvinyl chloride plastic can cause softening and transfer to adjacent surfaces because of plasticizer migration from the plastic. Before photocopying: The art and history of mechanical copying, 1780-1938. Process for developing silver halide recording materials, Application filed by EI Du Pont de Nemours and Co, Assigned to TEXAS COMMERCE BANK NATIONAL ASSOCIATION. Because it is essentially a thin tissue paper, carbon copy paper wrinkles easily but is actually quite strong. (d) an exclusive pre-paid publishing tool and non-instructional and non-illustrative resource for the scribes. The following example illustrates but does not limit the invention. narrow your search results put Last Name first inside quotation marks. Silver-halide print films are of two types: Polarity reversing and direct-duplicating. If color photocopies are displayed, they should be exposed to no more than 5,000 ft-c hours (50,000 lux hours) per year with a 3-year rest between displays. A protective gelatin layer was applied at a coating weight of 1.3 g/m2 on the emulsion layer on both sides. In accordance with this invention there is provided a process for the development of a photographic silver halide recording element comprising a support bearing at least one layer of a silver halide emulsion, the element containing a nonionic, fluorinated surfactant, the silver halide recording element being developed by treating with a developer containing at least 15 g/L of a dihydroxy benzene compound, at least 0.15 mole/L of an alkali metal sulfite, and a wetting agent in a concentration of at least 0.1 g/L at a pH no greater than 11.5. The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative It is not sensitive enough to be used as a camera negative film. Carbon copies may be typewritten or handwritten. Do not use in strong sunlight. Silver halide recording elements that can be developed are those particularly useful in medical diagnostics with X-rays and in reprography. Thermal prints of any kind should not be displayed. Silber Halogen Verfahren n.; Halogensilber Verfahren n. English-German reprography dictionary. Experience has shown that the binder resins in xerographic copies are vulnerable to blocking to adjacent surfaces with heat or pressure. Wax- or oil-based carbon black or color ink (w/ aniline dye), Oil-based carbon black or color ink (w/ aniline dye), Wax- or oil-based carbon black or color ink (will contain aniline dyes), Paper treated w/ gelatin or alum/rosin sizing, Silver sulfide, silver halide, elemental silver, Paper (uncoated) or polyester transparency, Black toner (carbon black pigment in resin), Aniline, iron gall, or carbon black pigment ink, Paper (with or without resin-coated layers). 2009. Encyclopedia of printing, photographic, and photomechanical processes: Containing invaluable information on over 1500 processes. The concentration of the wetting agent in the developer solution generally decreases more or less rapidly during use because of developer replenishment and because some is removed by occlusion on the silver halide elements being processed. Abstract. A preferred pH range is between 9 and 11.5. 07/606,086 filed Oct. 30, 1990, now abandoned. See Inkjet Print for additional information about inkjet inks and papers. Best film type for census records. SECURITY INTEREST;ASSIGNOR:STERLING DIAGNOSTIC IMAGING, INC.;REEL/FRAME:007919/0405, Owner name: If the print appears well-processed and stable, it may be displayed for up to 30,000+ ft-c hours (300,000 lux hours) per year with a 1-year rest between displays. Silver-halide film should not be stored with other kinds of film. Diazo is a polarity maintaining copy.
