    • A method of producing vapor grown carbon fibers is provided in which coal is utilized as a source of an iron catalyst, as a source of hydrocarbon and sulfur, or both. The method includes the steps of introducing pulverized coal into a furnace containing a gas selected from the group consisting of hydrogen, hydrocarbon, nitrogen, ammonia, helium, or mixtures thereof, and maintaining the gas at a temperature from about 1000.degree.-1175.degree. C. to form the fibers. The coal has a sulfur content of from 1 to 6% by weight and may comprise high volatile bituminous coal. The use of coal to produce vapor grown carbon fibers provides a significant cost advantage over other starting materials and also provides an environmentally safe use for high sulfur content coal.
    • 提供了生产气相生长碳纤维的方法,其中使用煤作为铁催化剂的来源,作为烃和硫的来源,或两者。 该方法包括以下步骤:将粉煤引入含有选自氢,烃,氮,氨,氦或其混合物的气体的炉中,并将气体保持在约1000-111℃的温度 形成纤维。 煤的硫含量为1至6重量%,可包含高挥发性烟煤。 使用煤来生产气相生长碳纤维比其他起始材料具有显着的成本优势,并且还为高硫含量煤提供了环境安全的用途。

    • Carbon fiber with increased bulk density comprising vapor grown carbon fiber is provided. The preferred method of increasing the carbon fiber bulk density comprises mixing a vapor grown carbon fiber with a diameter of less than about 1 .mu.m and an initial bulk density of less than about 0.2 lb/ft.sup.3 with an aqueous-based solution, blending the mixture under high shear conditions, and drying the blended mixture. Upon drying, the mixture forms a carbon fiber mass with an increased bulk density having a final bulk density of at least about 3 lb/ft.sup.3. The increased bulk density carbon fiber pellets are ideally suited for use as reinforcing materials in rubber, plastic and the like. Preferably, the aqueous-based solution is a latex containing solution and latex is deposited on the fibers.
    • 提供了包含气相生长碳纤维的具有增加的堆积密度的碳纤维。 增加碳纤维堆积密度的优选方法包括用水基溶液混合直径小于约1μm的初始堆积密度的小于或等于约0.2lb / ft 3的气相生长碳纤维,将混合物 在高剪切条件下干燥混合的混合物。 干燥后,混合物形成具有至少约3lb / ft 3的最终堆积密度的堆积密度增加的碳纤维块。 增加堆积密度的碳纤维颗粒理想地适合用作橡胶,塑料等中的增强材料。 优选地,水基溶液是含乳胶的溶液,并且胶乳沉积在纤维上。

    • A room service table includes a frame, a tabletop including folding side portions and wheels. A push handle assembly mounts to an underside of the table and includes a handle portion and a hinge body portion. The handle portion includes a grip, a support portion and a hinge pin portion. The hinge body mounts to the tabletop and includes barrel portions supporting the hinge pin portion. The hinge pin portion has a tab formed in an end thereof engaging a complementary slot formed in the hinge body portion. The slot includes a first section and a second section that receive and retain the tab for aligning and securing the handle at the use position and at the storage position. The biasing member urges the pin toward the slot. Rotation is accomplished by sliding the handle axially so that the tab disengages the slot and rotating the handle to the desired position and then releasing the handle.
