Abstract: A cover replicating the appearance, texture, and surface features of a regulation baseball enclosing a flexible, hollow, spherical core. The core is fabricated from a pair of substantially similar semispherical shells made of a homogeneous, waterproof composition and bonded one to another at the circumferential edges. The composition from which the core is formed includes by weight 30-40 percent styrene butadiene rubber, 16-20 percent natural rubber, 33-37 percent calcium carbonate, and 5-9 percent silica powder, as well as diphenyl guaniden, rubber cure accelerator, and traces of zinc oxide and sulfur. The outer diameter of the core is approximately 2.6-3.0 inches with a wall thicknesses in the range of approximately 0.08-0.16 inches. The core with the cover assembled thereon has a weight of approximately 2.5-3.5 ounces, less than that of a regulation baseball, and an outer diameter substantially equivalent thereto. The cover includes two pieces of synthetic leather secured at the edges with raised herringbone stitching in the pattern of a regulation baseball. Optionally, a layer of twine may be tightly wound in random fashion about the core and the outer cover may be adhered to the structure beneath it using an adhesive. Due to its flexibility and lighter weight in relation to a regulation baseball, the disclosed substitute baseball affords an enhanced margin or safety to young and inexperienced players.

Abstract translation: 覆盖一个包围柔性中空球形核心的调节棒球的外观，质地和表面特征的盖子。 芯由一对基本上相似的由均匀的防水组合物制成的半球形外壳制成，并且在圆周边缘处彼此粘合。 形成核心的组合物包括重量百分比为30-40％的丁苯橡胶，16-20％天然橡胶，33-37％碳酸钙和5-9％二氧化硅粉末，以及二苯胍，橡胶固化促进剂 ，和痕量的氧化锌和硫。 芯的外径约为2.6-3.0英寸，壁厚在大约0.08-0.16英寸的范围内。 具有组装在其上的盖的芯具有大约2.5-3.5盎司的重量，小于调节棒球的重量，以及与其基本相当的外径。 盖子包括两块合成皮革，固定在边缘，并以调节棒球的图案提升人字形拼接。 任选地，缠绕一层线可以围绕芯部以随意的方式紧密缠绕，并且外盖可以使用粘合剂粘附到其下方的结构上。 由于其规则棒球的灵活性和较轻的重量，所披露的替代棒球为年轻和缺乏经验的球员提供了更高的利润或安全性。

Abstract: A method to manufacture a carbon fiber electrode comprises synthesizing polyamic acid (PAA) as a polyimide (PI) precursor from pryomellitic dian hydride (PMDA) and oxydianiline (ODA) as monomers and triethylamine (TEA) as a catalyst, adding dimethylformamide (DMF) to the polyamic acid (PAA) solution to prepare a spinning solution and subjecting the spinning solution to electrostatic spinning at a high voltage to obtain a PAA nanofiber paper, converting the PAA nanofiber paper into a polyimide (PI) nanofiber paper by heating, and converting the polyimide (PI) nanofiber paper into a carbon nanofiber (CNF) paper by heating under an Ar atmosphere. Also, the method to manufacture a polyimide carbon nanofiber electrode and/or a carbon nanotube composite electrode may utilize carbon nanofibers having diameters that are lessened by optimizing electrostatic spinning in order to improve spinnability.
