It is also controlled and energized by a humidistat located within the building to force outside air into the building and diminish the humidity therein when needed.

Abstract: A method for producing embossed designs on work surfaces such as on molds, rolls or dies. A photomechanically imageable transfer material is exposed to the design to be embossed. The material is developed and the acid resistant design material remaining on a backing sheet is mechanically transferred to the work surface by burnishing the back of the backing sheet. The surface is then etched and the acid resistant design elements removed so that the embossed work surface is ready for use.

Abstract: A reed relay wherein the coil and switch terminals are disposed generally in planes parallel to the axis of the relay. A bobbin is molded onto a switch consisting of glass-enclosed contacts with leads projecting therefrom. Coil terminals are molded integrally with the flanges of the bobbin. The coil leads are connected to one side of the terminals which are then bent into notches in the flanges. The switch terminals are formed alternatively by bending them into notches in the bobbin flanges to project at right angles to the axis of the bobbin or by laying a separate terminal in the bobbin and welding the terminals to it. A housing is molded around the bobbin and the respective coil and switch terminals are bent into an in-line position.
