Abstract: An illustrative embodiment of the invention provides a technique for applying the deep heat capabilities of microwave energy to the problems of ceramic ware production. A plaster-of-paris mold, filled with "slip" is exposed to microwave energy to produce a "green body" in a few minutes. After excess "slip" is decanted and the "green body" is exposed, the mold is dried through microwave heating, weighed and then brought up to the proper degree of moisture by spraying and weighting. The "green body", moreover, after finishing is further dried through microwave heating.

Abstract: An optoelectronic synchro generator which comprises at least one photoelectric circuit element which includes a light source and an associated receiver. A rotatable shaft has mounted thereon, for rotation therewith, elements which define at least one optically effective surface spaced from the axis of rotation of the shaft and through which light coming from the light source impinges on the receiver when the surface is in a predetermined position during the rotation of the shaft. A removable cover covering the shaft and the photoelectric circuit element and a shield disposed between the receiver and the optically effective surface prevents the impingement of stray light on the receiver when the cover is removed.
