Abstract

Method and device for producing hollow microphones from an organic material in the form of a film. The production of microspheres has place in an apparatus, from a material former of the inorganic film, which may be constituted by a wide variety of materials and compositions, particularly glass compositions. These compositions heat up to a temperature of 2,000 to 2,800 gf, variable according to the compositions, to which it functions and easily flows. The liquid film is transvertly formed to a hole, which is applied to an inert blowing gas or a metal vapor at positive pressure on the interior surface to inflate and form the microsphere. This is submitted during its training to a pulsing external pressure field that helps its training, as well as to separate from the hole. A conveniently supplied fluid off stops the microspheres to solidify them. The microspheres can contain a high vacuum when a metal vapor, like blowing gas, is used, and the vapor is cooled and is deposited through a smooth metal coating on the inside surface of the microsphere. Use as isolation and/or filling materials. (Machine-translation by Google Translate, not legally binding)
