    摘要： A method for the manufacture of a linear or annular ultrasonics antenna array for the megahertz range, which consists in providing a laminate of alternating layers of unsintered ceramic and spacing layers, the spacing layers being composed of a filler material which is heat fugitive at the sintering temperature of the ceramic, the spacing material also including refractory grains distributed therein of a size which corresponds to the spacing desired between the ceramic layers, sintering the laminate to thereby liberate the filler material and leave voids between the refractory grains, impregnating the resulting laminate with a polymerizable resin to bond the sintered ceramic layers together, and separating the resulting laminate into individual transducer elements.

    摘要： An insulation material having relatively high moisture permeability, includes an inner sheet of expanded polystyrene of substantial thickness. Attached to the polystyrene is an impermeable kraft supported aluminum foil outer layer having the paper side facing the polystyrene. An adhesive layer is provided to join the outer layer to the inner layer. Finally, a plurality of moisture permeation creating perforations are intruded through the outer layer and the adhesive layer and extend into the inner layer to render the outer layer and adhesive layer moisture permeable. The perforations are formed by bonding the layers with the adhesive, allowing the adhesive to set and thereafter passing the bonded layers against a means for forming perforations.Particularly preferred for forming the perforations is a roller having an inner cylinder, an outer shell covering the cylinder with a plurality of holes therein corresponding to a predetermined pattern, and tacks having a pointed end or spike and a head end for the forming of perforations. The tacks are located in each of the holes in the shell such that the pointed end of the tack extends outward through the shell. Finally, spacers are positioned between the cylinder and the shell by sufficient distance to trap the tacks without restricting limited movement of the tacks. The spacers substantially prevent relative movement of the shell and the cylinder toward and away from each other.
