    • A method of molding a composite material which includes a fiber reinforcement within a resin comprises laying alternately on a mold first and second layers of fiber material pre-impregnated with uncured resin, where the resin content of the first layer is different from that of the second layer and the combination of layers gives the desired overall total volume fraction of fibers and resin in the laminate, enclosing the layers within an impervious membrane, evacuating the membrane and applying heat to the layers to flow gellate and at least partially cure the resin and during the process to allow released gasses and vapors to flow along the layers of lower resin content towards the membrane for subsequent evaluation.

    • An advertising display apparatus comprising a hollow receiving tube with an essentially closed distal end and an essentially open proximal end enclosed within a base region, means for retaining a preprinted material inserted through said base region, wherein the hollow receiving tube comprises a plurality of faces where at least one face is transparent and through which said preprinted material may be viewed. The plurality of faces comprising the hollow receiving tube are preferably of a convex shape. Included within the base region is a retention lip which extends into and partially occludes the essentially open proximal end of the hollow receiving tube. The base region may include additional fitments to allow for attachment of the display apparatus to surfaces not of a flat horizontal orientation. The base region may further include means for producing light or sound.

    • An advertising display apparatus comprising a hollow receiving tube with an essentially closed distal end and an essentially open proximal end enclosed within a base region, means for retaining a preprinted material inserted through said base region, wherein the hollow receiving tube comprises a plurality of faces where at least one face is transparent and through which said preprinted material may be viewed. The hollow receiving tube in conjunction with the essentially closed distal end and the proximal base end act to retain the preprinted material in a protected environment which aids in ensuring a clean, quality representation of the preprinted material for protracted time periods, especially in environments where people may come into repeated contact with the display apparatus and it is desirable to maintain the quality of the preprinted material, such as restaurants, trade shows and retail sales stores. The plurality of faces comprising the hollow receiving tube are preferably of a convex shape for enhancing retention of the preprinted material and ensuring positive engagement of the preprinted material up to and against the respective face. Included within the base region is a printed material retention lip which extends into and partially occludes the essentially open proximal end of the hollow receiving tube. The base region is designed to allow the display apparatus to remain stable when set upon a flat horizontal surface and may optionally include additional fitments to allow for attachment of the display apparatus to surfaces not of a flat horizontal orientation. The base region may further include means for producing light or sound so as to enhance the attractive attention value of the display apparatus.

    • A transducer for use in surface ship applications includes a prestress element for providing additional compressive force to an electromechanical driver disposed within the transducer. The transducer includes a shell having inner portions, an electromechanical driver having end portions coupled to inner portions of the shell, and a block prestress element disposed between one of the end portions of the driver and the inner portions of the shell. The block prestress element is fabricated from a shape memory alloy which can be deformed within a first temperature range and reverts back to its original shape when exposed to a temperature above the first temperature range. This characteristic provides for the generation of additional stresses which may be desired for providing protection to the electromechanical driver from unwanted tensile forces. This approach for providing additional compressive force to the driver allows the insertion of the stacked ceramic electromechanical driver within the shell with prestress levels generally not achievable without possible damage to the shell.
    • 用于表面船舶应用的传感器包括用于向设置在换能器内的机电驱动器提供额外的压缩力的预应力元件。 换能器包括具有内部部分的壳体,具有连接到壳体的内部部分的端部的机电驱动器以及设置在驱动器的一个端部和壳体的内部之间的块预应力元件。 块预应力元件由形状记忆合金制成,该形状记忆合金可在第一温度范围内变形,并且当暴露于高于第一温度范围的温度时回复到其初始形状。 该特性提供了产生额外的应力,这可能是为机电驱动器提供免受不必要的拉力的保护所需要的。 用于向驱动器提供额外的压缩力的这种方法允许堆叠的陶瓷机电驱动器在壳体内插入,其具有通常不可实现的预应力水平,而不会对壳体造成损害。
