Patent EP-0501835-A2 (EP)
Inventor: LENKE JAMES H
IPC: G01N23/223
Filed: 1992-03-02
Abstract: An instrument (10) and a method for the preparation of a sample for analysis provides a crucible holder (100,102,103) which improves the holding and control of a melting crucible (130) during operation of the device for agitating a powdered sample and flux while being heated. The crucible holder is coupled to an agitation assembly (200) which provides independently controlled operation on two different axes (X-Y) using separately adjustable variable frequency and amplitude motion along each of the two operating axes to provide an infinite number of agitation patterns for the crucible. The heating flame is controlled by controlling the supply of compressed air and a combustion gas. A pilot burner (502,504,506) is provided which both ignites the main burner (300,302,304) located under the crucible and preheats the casting dish (530) to a temperature which is substantially the same as the crucible. The pilot also can direct air only to the casting dish for controllably cooling the sample melt to form the sample bead. Invertible scoops (602,604,606) can deliver a non-wetting agent to the crucibles.

Title: Automated image calibration
Inventor: SOBOL ROBERT E
IPC: B41J5/30
Filed: 1992-05-28
Abstract: A document processing system (DPS) having a closed feedback loop (291) for improving the quality of the printed form (314) of images that have been scanned into the DPS by scanners (224). The DPS includes a print path. The closed feedback loop automatically calibrates the print path such that printed documents have a true representation of the scanned image. The closed feedback loop operates as follows. First, a calibration image for the print path is created (404). Then, the calibration image is processed in the DPS (408). Then, distortions in the calibration image, caused by the processing, are measured (412). Then, calibration coefficients for offsetting the distortions are calculated (412). Finally, the image of the original document is precompensated by modifying the image according to the calibration coefficients (416).

Abstract: To measure distance in accordance with the principle of pulse transit time, the received signal obtained after each transmission of the pulse is stored as echo profile and the useful echo is determined from the stored echo profile. To suppress repetitive interference signals, a fixed threshold profile matching the measuring environment is formed and used in each evaluation of a stored echo profile. To be able to take into consideration fluctuations in the characteristics of the received echo profile rapidly without having to change the fixed threshold profile for this purpose, a sliding threshold profile in the form of a monotonically falling curve is formed from a stored echo profile. The greater value in each case of the mutually corresponding values of the sliding threshold profile and of the fixed threshold profile is used for forming a resultant threshold profile which is used in each evaluation of stored echo profiles. <IMAGE>

Abstract: A chain organopolysiloxane is obtained by polymerizing a fluorine-containing cyclotrisiloxane of the general formula :
     (wherein R 1  is a monovalent hydrocarbon group, and Rf is a perfluoroalkyl group or perfluoroalkyl ether group)

Abstract: The present invention concerns methods of coating heat and oxidation resistant coating materials which, by being coated and sintered onto the surface of an object to be treated, such as a metal, a firebrick, etc., improves the resistance to heat, oxidation, wear, etc. of incinerators, boilers, heat exchangers, internal combustion engines, heat insulations for braking devices etc. which uses the abovementioned object treated. 
     By blending high melting point materials, such as zirconium dioxide, aluminum oxide, magnesium oxide, etc. with auxiliaries which serve a catalytic role, the high melting point materials and the surface of the object to be treated are caused to melt at temperatures no higher than the melting point of the object and a ceramic compound is formed on the surface of the object. Furthermore, by blending auxiliaries which provide the effects of making the coating material accommodate for the thermal expansion of the object and of restricting thermal oxidation, the coalescence with the object and the oxidation resistance of the object are increased. An aqueous solution of potassium silicate of a specific concentration is mixed with powder materials to put the ingredients of the coating material in a solution form. Since this is applied by coating onto the surface of the object and sintering at temperatures no higher than the melting point of the object, the degradation and thermal oxidation of firebricks, carbons, etc. may be restricted and a heat resistant coating which does not separate or crack may be formed on metal surfaces.
