Abstract: ABSTRACT OF THE DISCLOSURE Control apparatus for manipulator welding apparatus is provided that includes a vision correction system for workpiece sensing.  During an initial teach mode, the manipulator is taught the desired welding path on a workpiece by the appropriate recording of data representing the welding path as an operator controls movement of the manipulator.  In addition to the data representing the taught welding path, data representing a refer-ence image or template is also recorded in the teach mode.  The reference image or template data is provided by a vision system including a camera carrier by the manipulator arm.  As successive workpieces are presented to the manipulator for performing the desired welding path, in a repeat work cycle mode the manipulator is controlled to move in accordance with the recorded taught data in a first repeat pass wherein images of the welding seam region are detected at successive points.  The vision system utilizing an image processor detects the deviation between the taught welding path and the actual welding path of the workpiece.  The control apparatus in response to the deviation data provided by the image processor in the first repeat pass corrects the recorded taught data to provide corrected welding path data for the particular workpiece orientation and geometry encountered by the manipulator.  During a second repeat pass of the repeat work cycle mode, welding of the actual workpiece seam is performed in accordance with the corrected welding path data obtained in the first repeat pass.

Abstract: ABSTRACT     Apparatus and method for converting heat to electrical energy by the use of one or more capacitors (23) having temperature dependent capacitance.  The capacitor is cycled between relatively high and relatively low temperatures by successive thermal contact with relatively high and relatively low temperature portions of a heat transfer medium (33) having a temperature gradient therein.  Upon heating of the capac-itor (23), the capacitance thereof is reduced, so that a charge therein is caused to expand into associated external circuitry in which it is available to do electrical work. The capacitor (23) is then cooled and recharged and the cycle is repeated.  The electrical output of the capacitor (23) results from the regenerative delivery of heat to and removal of heat from the capacitor by the heat transfer medium (33), and efficient conversion of heat to electric energy is thereby effected.

Abstract: ABSTRACT   An improved process for preparing the 2-alkylamino-5-alkyl-pyridine and 2-amino-5-alkylpyridine amination products of 3-alkylpyridines, comprising the step of initially reacting the base directly with the sodium salt of a primary alkylamine to produce the 2-alkylamino form, wherein the alkyl group in each reactant has from 1 to about 20 carbon atoms.  The sodium salt is preferably preformed in situ by adding the alkylamine to a dispersion of sodium in an organic solvent heated to about 100-120°C.  The substituted amination preferably proceeds at a temperature of about 100-140°C in a solvent such as toluene and under an inert nitrogen atmosphere.          The ratio of 2,5-:2,3- isomer products of the reaction is up to about 10:1 or more, with the effective yield of the 2,5-alkylated isomer being about 25% or more.  This recovered 2-alkylamino-5-alkylpyridine product is readily dealkylated by reaction with hydrobromic or hydriodic acid with or without the presence of a pyridine hydrohalide salt to obtain the 2-amino-5-alkylpyridine product which has proven uses in herbicidal, insecticidal and pharmaceutical applications.
