    • Disclosed are various embodiments of cross-wind turbines that are capable of providing high efficiencies over a wide range of wind velocities. An airfoil stator causes wind to accelerate along its surface and creates a low pressure area on the leading face of the rotor blade during the power stroke. A blocking stator blocks wind from impeding the movement of the rotor blades during the return cycle and directs wind onto the trailing face of the rotor blades during the power cycle. A large pressure differential is created between the leading face of the rotor blade and the trailing face of the rotor blade during the power cycle which creates a large amount of force that rotates the rotor blade about the central shaft. In some embodiments, gaps are provided between the inside edge of the rotor blade and a stationary shaft which vents wind collected by the rotor blade during certain portions of the rotation cycle. The vented wind increases the pressure on the trailing face of the rotor blades during the return cycle to further assist in the efficiency of this system.
    • 公开了跨风力涡轮机的各种实施例,其能够在宽范围的风速下提供高效率。 翼型定子使得风沿其表面加速并且在动力冲程期间在转子叶片的前表面上产生低压区域。 阻塞定子阻止风在返回循环期间阻止转子叶片的运动,并且在动力循环期间将风引导到转子叶片的后表面上。 在动力循环期间,在转子叶片的前表面和转子叶片的后表面之间产生大的压力差,这产生了使转子叶片围绕中心轴旋转的大量力。 在一些实施例中,在转子叶片的内边缘和在旋转周期的某些部分期间通过转子叶片收集的风的静止轴之间设置间隙。 通风风在返回循环期间增加转子叶片后端的压力,以进一步提高该系统的效率。

    • A process of making a tack-free gel is disclosed comprising the steps of providing a mold defining a mold cavity, the mold cavity comprising a plastic material; pouring or injecting a molten gel having a high molding temperature into the mold cavity; and forming the tack-free gel as a thin layer of plastic of the mold cavity is melted over the gel. The forming step further comprises cooling the gel from the molten state to a solidified state. The melting temperature of the plastic material is lower than the molding temperature of the gel; and the higher the temperature differential, the greater the melting of the plastic material and the thicker the layer of the plastic material on the surface of the gel. The mold may be formed of low-density polyethylene (LDPE). With the process of the invention, the heat of the molten gel at its molding temperature is transferred to the surface of the LDPE mold so as to melt a thin layer of the LDPE. The mold may comprise a mold base having a plurality of mold holes forming a plurality of mold cavities, each of the mold holes comprising an axial pin to mold an axial hole through a center of the gel, an LDPE cylinder providing a predetermined inside diameter for the mold, and an LDPE disc mounted on the axial pin and disposed at the bottom of each mold cavity in the mold base. The process may further comprise the step of dabbing the gel in a low-friction powder such as polytetrafluoroethylene (PTFE) and a lubricant. The mold may further comprise a mold top disposed axially of the mold base and comprises a plurality of holes forming a plurality of cavities, each of the mold top holes is adapted to receive the LDPE cylinder, and a second LDPE disc disposed at the top of each mold cavity of the mold top.
    • 公开了制造无粘性凝胶的方法,包括以下步骤:提供限定模腔的模具,所述模腔包括塑料材料; 将具有高成型温度的熔融凝胶注入或注入模腔中; 并且将形成无粘性凝胶作为模腔的塑料薄层在凝胶上熔化。 形成步骤还包括将凝胶从熔融状态冷却至固化状态。 塑料材料的熔化温度低于凝胶的成型温度; 并且温差越高,塑料材料的熔化越大,并且凝胶表面上的塑料材料层越厚。 模具可以由低密度聚乙烯(LDPE)形成。 通过本发明的方法,熔融凝胶在其成型温度下的热量转移到LDPE模具的表面,以熔化LDPE的薄层。 模具可以包括具有形成多个模具腔的多个模具孔的模具基座,每个模具孔包括轴向销,以模制通过凝胶的中心的轴向孔,提供预定内径的LDPE圆筒, 模具和安装在轴向销上并设置在模具基座中的每个模具腔的底部的LDPE盘。 该方法还可以包括在诸如聚四氟乙烯(PTFE)和润滑剂的低摩擦粉末中浸渍凝胶的步骤。 模具还可包括设置在模具基座的轴向上的模具顶部,并且包括形成多个空腔的多个孔,每个模具顶部孔适于接纳LDPE圆筒,并且设置在第二LDPE圆盘的顶部 模具顶部的每个模腔。
