Method of generating a uniform radius on a workpiece by electrochemical means wherein a nozzle is positioned in spaced relationship to an edge of a workpiece, a charged electrolyte is passed through the nozzle to impinge upon the edge, and the nozzle is moved along the contour of the workpiece to thereby provide controlled removal of any irregularities on the edge, resulting in a smooth radius being formed at the edge.

The in situ thermal decomposition of specified furoxans to yield dinitrile oxides is used to modify a polyfunctional species. Preferred uses involve cross-linking of polymers, especially rubbers, but the process may also be used to form polymers from monomeric materials or to bind additives to polymeric substrates. Compositions incorporating polymeric materials and suitable furoxans may be used as "one-shot" casting systems or be produced in the form of thermally curable sheets, etc, having usef...

This patent relates to a method for the generation of hydrogen, particularly for fuel cells, as well as apparatus for practicing the method. According to the invention, particles of magnesium are reacted with water in the presence of at least one cobalt oxide and at least one water-soluble chloride. Aluminum may advantageously be included with the magnesium. This abstract is neither intended to define the invention covered by this application, which, of course, is measured by the claims, nor is ...

A device for generating an easily accessible, substantially uniform and parallel magnetic field. A number of identical solenoid posts are arranged symmetrically about a central axis and secured by corresponding ends to a pair of end-plates of magnetic material, to form an open, cagelike structure. Equal magnetomotive forces are applied by separate windings on each post, the resulting magnetic field in the space between the end-plates being substantially uniform and parallel to the axis, any non-...

Heat is generated by combustion of coal or like carbonaceous fuel reactant dissolved in molten salt. The generated heat is transferred to steam by an alternating sequence of direct contact heat exchanges of the salt and steam with a common heat transfer medium.

A method and system for determining the advance of a curve to be created on an X-Y plane, wherein the distances X and Y between the current position of the curve and a specific point assumed in correspondence with the nature of the curve and along the x-axis and the y-axis of the plane are utilized. The large-small relationship of the pulse distribution densities to the axes is decided from the large-small relationship of X and Y. As a result of this decision, the axis of higher pulse distributi...

Method and apparatus for performing a plurality of operations on a workpiece without the necessity of removing the workpiece after each operation, in which a template is provided, the curved border of which is shaped in accordance with the contour desired to be formed on a workpiece. An elongated, flexible member is fastened at a point on one side of the template and is pulled taut around a corner on the other side of the template. The length of the member is such that when the member is pulled ...

A system for enhancing the operation of an oxygen extractor by reacting an oxygen enriched effluent with heated beds of barium oxide to reduce the time involved in sequentially producing pure oxygen from these beds by lowering the pressure therein. A separator which fractionalizes air into the oxygen enriched effluent produces a nitrogen enriched effluent as a by-product. The nitrogen enriched effluent is carried in a conduit to cool the produced oxygen which is produced during transfer to a sto...

Light scattering pigment powder particles, surface treated to minimize inparticle cohesive forces, are dispensed from a jet mill deagglomerator as separate single particles to produce a powder contrail having maximum visibility or radiation scattering ability for a given weight material.

Readily maintained and operated apparatus for generation of combustible gas mixture and motor fuels from coal with cycling of the heat energy sources for heating coal.
