Abstract: ABSTRACT OF THE DISCLOSURE:            A process of calcining limestone or hydrated lime by a thermal treatment with hot gases in an oxidizing atmosphere in a rotary kiln through which the kiln atmosphere and the charge are contercurrently conducted and which is fed with fuel through shell burners.  The process of the invention is characterized in that different fuels which serve to produce hot gases and which release SO2 and SO3 in different quantities per unit of calorific value are introduced into the rotary kiln in such a manner that the fuel which releases a larger quantity of SO2 and SO3 per unit of calorific value is supplied to the upper portion of the rotary kiln and the fuel which releases a smaller quantity of SO2 and SO3 per unit of calorific value is supplied to the lower portion of the rotary kiln.  The advantages of the inven-tion reside mainly in that fuels which release SO2 and SO3 in relatively large quantities may be used to produce a quicklime which has a high reactivity and a low sulfur content in a process which involves low fuel costs and a low structural ex-penditure.

Abstract: ABSTRACT OF THE DISCLOSURE:           Copper based substrates for use at high temperatures in oxidizing atmospheres are made up of a copper core overlaid with a protective nickel oxide barrier layer formed in situ and an external protective layer of nickel.  The process for forming the protective nickel oxide barrier layer comprises the steps of sub-jecting the copper core to oxidation to form a cuprous oxide sur-face layer over the copper core, reducing the surface of the cu-prous oxide layer to regenerate copper to regain conductivity, plating a surface layer of nickel over the      copper layer, and annealing the coated copper core to scavenge at least some of the oxygen from the cuprous oxide layer and react it at the interface with the plated nickel layer to form the protective nickel oxide barrier layer.  The oxidation reduction steps may be carried con-tinuously on a copper core which is moved through a reactor having an oxidation zone fed with oxygen, a reduction zone fed with hydro-gen and a stabilizer zone separating the oxidation and reduction zones and fed with an inert gas.  The reactor is maintained at a temperature such as to allow the oxidation and reduction reactions.

Abstract: ABSTRACT OF THE DISCLOSURE      A plurality of sensors, each generating distinct signals in response to the passage of leading and trailing edges of car wheels, are positioned along the rail at a height above the rail to detect the passage of a selected chord on the wheel tread. The distances between initial sensors and the final unit equal the various selected chord lengths on conventional sized wheels. When one of the initial sensors detects the passage of the trailing edge of the wheel at the chord level simultaneously with the detection of the leading edge of that wheel by the last unit, the output signals are applied to a logic circuit, which registers a wheel of corresponding diameter.  Additional sensors placed immediately adjacent the final sensor provide measure-ment of actual wheel diameters slightly less than the standard sizes to wheel wear.  When the sensors detect a gap in the tread chord, as a word wheel passes, greater than a predetermined length for each diameter wheel, an indication is provided of a worn wheel requiring replacement.  A second set of sensors posi-tioned on the other side of the rail measures the flange height to also indicate wheel wear.  All measurements are determined by logic elements and supplied to the yard control system.  The diameter and tread thickness measurements are used to supply a corresponding wheel rotational inertia factor to the speed control system while tread and flange wear indications indicate cars requiring immediate wheel replacements.

Abstract: Abstract of the Disclosure An imbalance determining system for a dynamic balancing machine for two-plane balancing of rotary elements such as vehicle wheel-and-tire assemblies includes a chuck and spindle mounted in a spindle housing in vibration-isolation orientation on a machine base.  The rotary element is brought to speed by one or more drive mechanisms which are mounted on the machine base to move between a driving orientation in contact with the rotary element and a storage orientation out of contact with the rotary element.  Vibra-tional forces resulting from imbalance in the moving rotary element are trasmitted through the spindle to the housing.          Two vertically spaced load cells are mounted adjacent the spindle housing, and are responsive to forces transmitted through the spindle to generate input electrical signals related to the amounts and locations of imbalance in two planes of the rotary element. These input signals are processed to generate a system of equations soluble to resolve the imput signals into signals indicative of the amount and location of imbalance in each of the two planes.

Abstract: ABSTRACT OF THE DISCLOSURE A pictorial ink jet printer is disclosed. The printer uses a linear array of nozzles each of which records a segment of a row of pixels in a given raster pattern.  The pixel segment is recorded by electrostati-cally deflecting the ink drops from a nozzle to the pixels contained within the segment.  The drops from adjacent nozzles are "stitched" or aligned to these ideal pixel positions by aligning the ink drop streams to drop position sensors.  Two sensors are used for each nozzle. Preferably, adjacent nozzles share sensors.  The sensors are spaced relative to each other to very close toler-ances.  Consequently, alignment of each nozzle to its two drop position sensors means that the drops from adjacent nozzles are aligned or "stitched."

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus for pulling a strand or intestine from a convoluted intestine, such as removed from an animal, and for removing the ruffle fat from the intestine by severing, is disclosed herein.  The leading end of the convoluted intestine is initially separated from the remaining bulk of convoluted intestine for insertion into the pulling apparatus which includes a work surface inclined downwardly from an entrance end to an exit end.  Between the exit end and the entrance end are a pair of opposed grip-ping belts, each mounted parallel to the work surface and defining a path between them along which the intestine strand may travel as it is compres-sively engaged on each side by the belts.  As the belts are driven, the re-maining bulk of convoluted intestine is restrained and the belts progres-sively pull the strand of intestine away from the convoluted bulk.  Ahead or the gripping belts at the entrance end of the apparatus is a circular knife blade which is mounted in a plane parallel to the work surface and at an elevation above the work surface that permits a strand of intestine to be pulled beneath it while the ruffle rat attached to the upper circumferential portion of the strand is held against, and above, the circular cutting knife to sever the ruffle fat from the strand.  The circular knife and one gripping belt are each movable away from (1) an engaging position adjacent the strand pull path to (2) a clearance position spaced from the path to enable the leading end of the intestine to be manually placed in the path.  Pivotally mounted above the work surface at the exit end of the apparatus is a baffle plate movable by positioning means into the discharge trajectory of the intestine strand to deflect the intestine strand so as to control the trajectory and disposition of the strand as it passes from the exit end or the apparatus.
