Abstract: The invention is a pin for rolling dough to variable thicknesses, the variability being under immediate control by the baker. The pin carries a rotatable gage permanently mounted on the roller in such a way that the baker can almost instantly vary the thickness of the dough that he is about to roll without substituting elements on the rolling pin and/or altering the relationship of the physical elements on the rotatable gage that make the variable thickness of the dough possible.

Abstract: An electroacoustical transducer of the magnetic armature type having an efficient electromagnetic configuration with the armature being formed integrally with a support yoke. The yoke includes a base from which two arms extend generally parallel to the armature, the two arms engage pole pieces formed of laminations, and the vibrating end of the armature is positioned in the plane of the diaphragm and is connected thereto. The armature may include a boss or gusset adjacent to the contilever end of the armature to stiffen it and thereby raise the resonant frequency of the transducer. A casing is included which is spaced from the yoke and serves as a magnetic shield.
