Granted: 2003-11-18
Abstract: There is disclosed a new stainless steel alloy called High Purity M152(HP M152) which has all the desired properties of those of the prior art, but has unique resistance to embrittlement. Limiting phosphorus, tin, antimony and arsenic in the stainless steel alloy to a little more than trace amounts provides tremendous reduction in the amount of embrittlement which occurs. Additionally, reduction of the manganese and silicon contents from 0.7 and 0.3, respectively, to about 0.050% provides further benefit.      This alloy can be used in steam turbine and jet engine applications, as well as in gas turbines.

Granted: 2003-02-25
Abstract: In accordance with the present invention, these and other concomitant problems are solved. The present invention relates to a process for making copies of photographic originals in a photographic copying machine, comprising the steps of sectionally scanning the original being copied by a measurement system in a measurement station of the photographic color copying machine, feeding measured light that is transmitted or remitted from each scanned section of the original being copied to a detector configuration, converting the measured light into electrical signals as a function of wavelength and intensity of the measured light, digitizing the electrical signals to obtain color data for processing in a computation and evaluation unit, and analyzing the color data in an analysis unit to establish correction values. The step of analyzing further includes steps of (a) subjecting the color data to a reversible linear or non-linear standardization transformation that is order or film type specific, (b) converting the color data into normalized color values to provide initial data for the analysis unit, (c) forming film specific normalized correction values in the analysis unit from the normalized color values, taking into account color, density, and structural characteristics of the original being copied, and (d) converting the film specific is normalized correction values of the analysis unit into de-standardized correction values in a de-standardization unit that is attached to the analysis unit using a de-standardization transformation which is inverse to the standardization transformation, the de-standardized correction values also taking into account the color characteristics of the film material being copied. A  required amount of copying light is determined from the de-standardized correction values in an exposure calculation unit, and copies are made from the original being copied in an exposure station based on said copying light.

Abstract: A support arm may have outlets at the outer end of the arm providing access to compressed air, fume and dust extraction, and electrical power.  All utility conduits such as electric welding power supply conductors, air hoses, extraction ducts and electri-cal control conduits may be encased within the arm to protect them from damage, remove the hazard posed by conduits laying upon the shop floor and to provide for simple access to multiple utilities at a distance from the utility sources.  The arm comprises an inner boom (1) pivotally mounted to a stationary supporting structure (4), an outer jib (2), and a knuckle (3) pivotally joining the boom and jib.  The boom, jib and knuckle are operable in a horizontal plane to provide access to utility connections at the ou-ter end of the jib within an arc (51-54) defined by the outer extent of the arm.  A linkage (62-70) between the boom, knuckle and jib maintains equal angles between the boom, the axis of the knuckle and the jib to avoid uncontrolled movements of the knuckle relative to the boom and jib and to avoid kinking of the flexible conduits connecting from the outer end of the boom, through the knuckle to the inner end of the jib.
