    摘要： Processed plant fine fibers such as those from the mesocarp of a coconut together are blended with a biodegradable plastic to produce a biodegradable plastic product that can be further made into other items. Plastics thus made from coconut husk fine fiber powder will return to the environment after disposal much more rapidly than those without coconut husk fine fiber powder. In the process, a dry compressed plant fine fiber powder is created from fine fibers of the coconut mesocarp. An example product created from this raw material is composed of 10 to 40% by weight of dry coconut husk powder mixed with environmentally degradable plastic. Environmentally non-degradable plastic may be added to the dry powder as a biodegradation rate modulator to create a modified raw material with a modified biodegradation rate. Plastic additives, standard in the industry, can be added to achieve additional desired properties. For example, a surface active agent may be added in order to increase the degree of processability; a colorant may be added to increase marketability; pesticides may be added as needed in order to protect the product or the soil in which the product is disposed from insects; and/or polymerization modifiers such as cross-linkers, monomer derivatives, heteromonomers, curing agents, etc. may be utilized to vary the properties of the base plastic.

    摘要翻译： 将处理过的植物细纤维如来自椰子的中果皮的细纤维与可生物降解的塑料共混以生产可生物降解的塑料制品，其可以进一步制成其它物品。 由椰子壳细纤维粉制成的塑料，比没有椰壳细纤维粉的处理要快得多。 在此过程中，由椰子中果皮的细纤维产生干压缩植物细纤维粉末。 由该原料制成的示例性产品由10至40重量％的与环境可降解塑料混合的干椰壳粉末组成。 可以将环境不可降解塑料作为生物降解速率调节剂添加到干粉中以产生具有改良的生物降解速率的改性原料。 可以加入行业标准的塑料添加剂以达到额外的所需性能。 例如，可以加入表面活性剂以增加可加工性的程度; 可以添加着色剂以增加市场性; 可根据需要添加农药，以保护产品或产品从昆虫中排出的土壤; 和/或聚合改性剂如交联剂，单体衍生物，异型单体，固化剂等可用于改变基础塑料的性质。

    摘要： A method and machine for recovering silver and polyester from exposed photographic X-ray film of the type having a polyester base coated with a sheath of polyvinyladine chloride and a photosensitive silver emulsion. Sheets of the film are fed through baths of hot caustic which successively remove the silver emulsion and deposit it as a sludge from which the silver is recovered and remove the polyvinyladine coating to permit the polyester to be recovered in a commercially acceptable pure form. Where the film sheets may include some acetate based film, the apparatus will distinguish between the polyester and acetate and discard the acetate bases as scrap, after the silver emulsion has been removed.
