    • A method for removing volatile organic compounds from a contaminated gas stream (2) includes contacting the contaminated gas stream (2) with a nonvolatile organic liquid absorbent stream (4) under conditions effective to allow absorption of the volatile organic compound from the gas stream (2) into the absorbent stream (4) and separation of the absorbed volatile organic compound from the absorbent in separation apparatus (12) to provide a recycled absorbent stream (14) and a reclaimed volatile organic compound stream (28). An apparatus for removing volatile organic compounds from a contaminated air stream includes means (6) for contacting the contaminated air stream with an absorbent to allow absorption of the volatile organic compound by the absorbent and means (12) for separating the absorbed volatile organic compound from the absorbent.

    • Nonforce-imparting or passive dental components and appliances are provided possessing not only greater stiffness and strength but also generally higher mechanical properties than those exhibited by the commonly used dental polymers. They also are more esthetic and easier to process, form and adjust than dental metallic alloys, thereby allowing for superior and unique designs. The passive dental appliances or structural components are fabricated from an effective fiber reinforced composite material comprised essentially of a polymeric matrix and a fiber component embedded within the matrix. The fiber component of the composite material constitutes greater than 20 percent by weight of the composite material and the modulus of elasticity of the composite is greater than 0.5 x 10 psi. The passive components are produced by initially compounding an effective fiber-reinforced composite material having the requisite stiffness and strength characteristics, fiber orientation and void free wetting of the fibers and thereafter forming the composite into the dental device to achieve improved aesthetics coupled with ease of processing and structural stability.
    • 提供非强制性或被动牙科部件和器具,不仅具有比通常使用的牙科聚合物所显示的那些更大的刚度和强度,而且通常具有更高的机械性能。 它们还比牙科金属合金更美观,更容易加工,形成和调整,从而允许优异和独特的设计。 被动牙科器具或结构部件由有效的纤维增强复合材料制成,该复合材料基本上由聚合物基质和嵌入基体内的纤维成分组成。 复合材料的纤维组分构成复合材料的大于20重量%,复合材料的弹性模量大于0.5×10 6 psi。 被动部件通过最初复合具有所需的刚度和强度特性,纤维取向和纤维无空隙润湿的有效的纤维增强复合材料制成,然后将复合材料形成牙科设备以实现改善的美观性以及加工容易性 和结构稳定性。
