Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for welding studs to workpieces are provided.  The invention is particularly concerned with welding studs to workpieces made of materials having relatively low electrical resistance but covered with layers of other materials having higher electrical resistance, a common example being metal workpieces having painted surfaces.  In order for the stud to make effective electrical contact with the workpiece at the beginning of the welding cycle, the paint must be eliminated; in accordance with the invention, this is accomplished by rotating the stud which effectively removes the portion of the paint in contact with the stud.  Electrical contact can then be established between  the stud and the workpiece to enable the welding cycle to be initiated.

Abstract: VORTEX COAGULATION MEANS AND METHOD FOR WASTEWATER CLARIFICATION          Abstract of the Disclosure:           Raw wastewater to be clarified is routed in an apparatus which directs the wastewater in an improved up-wardly directed vortex path that is above and open to a source of dense microbubbles. Impurities within the waste-water are urged toward the periphery of the vortex and coagulate, while the bubbles tend to pass up through a central core of the vortex.  The coagulated impurities and the bubbles approach the outlet of the vortex apparatus, whereupon a venturi-like effect is developed to accomplish an improved contacting of the coagulated impurities and the bubbles to form buoyant agglomerates.  The wastewaster and buoyant agglomerates flow together through the vortex outlet, after which the buoyant agglomerates may be permitted to float to the surface of the wastewater in a separate chamber.

Abstract: ABSTRACT      A liquid volume measuring apparatus has two parts. One part is a vessel into which the liquid to be measured is poured.  The vessel is transparent or has a transparent part and a scale (the other part) is arranged outside the vessel so that it can be seen through the transparent vessel wall.  There is an air gap between the scale and the vessel.  While the vessel is empty and the vessel is viewed from above and inside, the scale can be seen through the transparent wall.  However when the vessel is filled, those parts of the scale below the liquid level disappear because the light from these parts is totally internally reflected.  The volume of liquid in the vessel can thus be observed from above the vessel.

Abstract: CENTRIFUGAL SEPARATOR FOR FOOD PRODUCTS            Abstract of the Disclosure A centrifugal separator particularly adapted for food products removes foreign particles and objects which are denser than the main slurry.  It is especially effective in removing trace amounts of metal and bone fragments and other hard foreign material from meats, emulsified batters and other food mixtures without mat-erially changing the physical character of the input product.  The separator includes a centrifuge chamber with a central impeller, with specific spatial relation-ships between the impeller and the nearby axially dis-posed inlet opening.  Food batter or slurry is moved through the separator by the action of the impeller driving the slurry radially outwardly, in combination with a set of pumping vanes positioned adjacent to and communi-cating with the centrifuge chamber.  Foreign matter denser than the main batter or slurry collects on a peripheral wall of the chamber and is not discharged, it being gener-ally of small volume.  An easily removable stationary cover over the centrifuge chamber includes an annular ledge that forms a non-contacting seal with an annular projection on the rotatable chamber body to prevent leak-age of the purified slurry being pumped.
