Abstract: The method and apparatus of this invention is related to measuring a flow rate of a liquid having a density .rho. from a vessel having an inner cavity and a pouring channel. A flow sensor introduces a first gas flow into the liquid in the cavity at a first position, the inner cavity having a cross-sectional area A.sub.1 at the first position, and a second gas flow into the liquid in the pouring channel at a second position, the pouring channel having a cross-sectional area A.sub.2 at the second position, there being a vertical distance z between the first and second positions. A transducer provides an output signal proportional to a pressure differential p.sub.1 -p.sub.2 between the first and second gas flows. A processor receives the output signal and determines the liquid flow rate m through the pouring channel according to the proportional relation ##EQU1## where g is gravity.

Abstract: A powder filling apparatus comprised of a frame means having a cylindrical channel extending therethrough. A cylindrical funnel means is rotatably mounted in the channel, the funnel means having a bore extending therethrough. The bore has an axial section for receiving a flow of powder and an angled section at a preselected angle from the axis for directing the powder flow from the funnel means. A drive means is operatively connected for rotating the funnel means.

Abstract: A method and apparatus for severing a stack of amorphous alloy ribbons in a softened state is disclosed. The method provides a smooth burr-free edge of close dimensional tolerance while preserving the desirable magnetic properties of the alloy. Resistance self-heating is applied to heat a localized portion of the stack to a temperature above the softening temperature of the alloy. Severing occurs adjacent the electrodes in an adjacent stack portion which is heated by diffusion from the directly heated stock portion.

Abstract: A method and apparatus for parting a deck of amorphous alloy ribbons in one operation is disclosed. Force is applied to a deck of ribbons to place it under tension. A localized zone in the deck is compressed and rapidly heated to the softening temperature of the amorphous alloy. The deck separates along a seam within the zone due to the tensile force and localized rapid heating. A high quality edge is produced where the separated ribbon edges are free of burrs, meltbeads or substantial cracking and chipping.

Abstract: The problem of working an amorphous alloy is overcome by heating the alloy at a rate of temperature increase above about 1000.degree. C. per minute. The amorphous alloy is worked by homogeneous deformation after its temperature has been very rapidly increased to above the softening temperature of the alloy. Desirable magnetic properties of the alloy are preserved by working the alloy in this fashion and also tool life is extended.

Abstract: A bundle of articles having at least one small dimension are cut in succession. Tension is developed on the top article of the bundle. Heat is applied rapidly to a seam of the top article to be cut. The separated parts of a top article are withdrawn from the path of the beam and the next article is exposed to the heat.

Abstract: A method of melt extraction of titanium alloys is provided. The alloys are those containing a high concentration of titanium and a significant amount of an alloying element selected from the group consisting of molybdenum, tantalum and columbium. Surprisingly, the extraction process is rendered feasible when the surface of the extracting mechanism is of molybdenum.

Abstract: The problem of working an amorphous alloy is overcome by heating the alloy at a rate of temperature increase above a certain rate. The amorphous alloy is worked as its temperature is still being increased. Desirable magnetic properties of the alloy are preserved by working the alloy in this fashion and also tool life is extended.

Abstract: A method of severing an article subject to hot short phenomena is taught. A seam of the article is heated to bring it to the hot short condition and to have the remainder of the article at a temperature outside of the hot short range. A force is then applied to the seam to cause the article to sever due to brittleness of the material of the seam.

Abstract: Thermal compensators comprising at least one metallic alloy in amorphous form which are especially useful in stabilizing magnetic devices under conditions of changing ambient operating temperature are provided.

Abstract: Metallic ribbon having cutout patterns therein is provided in continuous helical form. The cutout patterns may be situated to intersect either or both of the ribbon edges or may be situated entirely within the ribbon. The helical ribbon with the cutout patterns may additionally have a nesting, or self-stacking, feature.

Abstract: Metallic ribbon having cutout patterns therein is fabricated in continuous helical form by directing a melt stream or jet onto a rapidly moving patterned substrate surface.

Abstract: Metallic ribbon is provided in continuous helical form. The ribbon may be nested and/or manufactured with a continuous pattern of predetermined geometry in the inner and/or the outer edge as well as in the interior of the ribbon.

Abstract: A hard magnetic article made by casting a magnetically soft amorphous metal ribbon and shaping it to the form and size of the desired permanent magnet article, and then heat treating the resulting soft magnetic body and thereby converting the metal of the ribbon to the hard magnetic state.

Abstract: Metallic ribbon is fabricated in continuous helical form by directing a melt stream or jet onto a rapidly moving substrate surface. The axis of the crucible along which the melt stream or jet is cast is defined by an inverted cone with apex at the point of crucible axis intersection with the substrate surface.

Abstract: A magnetic alloy is cast as an amorphous metal ribbon and wound on a rotor shaft of a hysteresis motor and then heated to crystallize the metal ribbon and greatly increase its coercive force prior to assembling the rotor with the stator of the motor.
