An armature for a selectively engageable and disengageable coupling and a method of making the armature are provided. The armature includes a substantially annular body that is disposed about a first axis. The body may be formed by stamping or fine-blanking. One side of the body is hardened through a nitriding process. A grinding wheel is then applied at an angle to the same side of the body along a diametrical line of the body extending perpendicular to the first axis. As a result, the body is configured so that the thickness of the body increases as the distance from the diametrical line increases. In particular, the thickness of the body varies along each cross-section taken along the line from a minimum thickness at the innermost portion of the cross-section to a maximum thickness at the outermost portion of the cross-section. The inventive armature reduces galling, and the resulting noise, that occur during burnishing of couplings incorporating the armature.

Apparatus for use in controlling the firing of heat generators provides output signals having first or second different characteristics during preselected time periods, the times of occurrence and extents of which are readily changeable by variation of the settings of switches. A system includes night and day thermostats selectively connected with a heat generator under control of such apparatus.

Systems and apparatus for control of fueled heat generators

Time controlled switching apparatus is connected in series circuit with a steam pressure sensor and a line starter associated with a boiler firing system. The switching apparatus is rendered electrically conductive during spaced time intervals of successive hours whereby boiler firing occurs during preselected time periods and then only where generated steam is at preselected pressure level.
