Abstract: Cylindrical or cubical blanks for producing balls, in particular small balls for ball bearings and placed in a vertical tube positioned eccentrically above a grinding disc having a horizontal plane abrasive upper surface which forms the bottom of the tube. The blanks partially fill the tube to a depth many times the cross section dimension of the blanks. For example many thousand of the blanks may be put in the tube at one time. The disc is then rotated to grind and tumble the blanks in the tube and to produce circulation of the blanks in the tube continually to bring different blanks into contact with the abrasive upper surface of the disc.

In this manner all of the blanks in the tube are ground to approximately spherical shape.

Abstract: A lifting apparatus for elevating folding roof sections comprises a pair of jackknifing lifting bars. A hoist means transmits a pulling force to the bars, thereby enabling each bar to unfold from a initial folded configuration into an extended straight configuration.

Remaining roof sections, together with the first roof sections, are elevated to a desired pitch with the bars in the straight configuration by applying additional force. Additional force causes the bars to rotate from the vertical position into a generally horizontal position while lifting both first and second roof sections to the desired pitch. At the start of the lift, all roof sections are horizontally folded and substantially supported on first segments of hinge plates fastened thereto.

Abstract: A foam filled metal shell building column for dwellings and the like comprises one or more thin metal sheets formed as a hollow shell having a longitudinal load-bearing axis. The thin-walled hollow shell is filled with a core of a plastic foaming material including a suitable foaming agent which foams to fill the shell and to exert a force on the shell radially outwardly of the longitudinal axis thereby forming a solid composite column. The radially outward force deflects the shell and permanently places the shell in lateral tension to increase the load bearing capability of the column. When more than one sheet is used, the elongated edge portions of the sheets are configured to loosely interfit with one another when the shell is initially formed, and the plastic foaming material causes a positive locking of the interfitted edge portions. Thus thin, non-load bearing gauge aluminum is converted into a load bearing structural element.

Abstract: A method for continuously relieving residual stresses in hot extruded then cold drawn brass sections, particularly leaded yellow brass. In the disclosed method, the residual stress is localized near the surface of the brass section during cold draw by limiting the percentage reduction in cross-sectional area for the section as it passes through a smaller angle cold draw die. This is accomplished by using a cold draw die having a relatively small attack angle which minimizes the stress at the center of the brass section and localizes the residual stress to an area near the surface of the section. The configured extruded, cold drawn rod is mechanically worked by passing it through mechanical benders which are set to alternatively bend the rod out of alignment first relative to a horizontal longitudinal axis and then relative to a vertical longitudinal axis.

Abstract: The invention relates to the periodic interruption of normal control at the condensation temperature by cooling the condensing surface to a temperature well below the prevailing dew point for a time sufficient to provide a heavy growth and coalescence of the condensate so as to dissolve all of the soluble material and create a medium by which molecules of solute can migrate. Immediately after cooling, the condensing surface is heated to a temperature well above the prevailing dew point so as to cause total evaporation of the solvent (condensate) and recrystallization or precipitation of the solute into clusters or isolated colonies. The resulting change in mirror reflectance is compensated after total evaporation by automatic adjustment of the light intensity of the source.
