    • A process for treating manure using anaerobic digestion includes introducing manure into a mixing vessel containing a digester liquid and agitating and filtering a slurry formed therefrom to remove substantially all water insoluble solids, thereby leaving a liquid containing ammonia and reactive organic materials. The liquid is then heated and ammonia is removed therefrom to produce a substantially ammonia-free liquid containing reactive organic materials, which is cooled and placed in a digester containing anaerobic bacteria to convert the reactive organic materials in the liquid to biogas and to produce a digester liquid. The biogas is withdrawn and utilized to generate electricity, and a small amount of the digester liquid is withdrawn from the digester and recycled back to the mixing vessel. The water insoluble solids and ammonia removed during the process may be converted to ruminant animal feed and concentrated liquid fertilizer, respectively.
    • 使用厌氧消化处理粪便的方法包括将粪便引入含有蒸煮器液体的混合容器中,并搅拌和过滤由其形成的浆料,以除去基本上所有的水不溶性固体,从而留下含有氨和反应性有机物质的液体。 然后将液体加热并从其中除去氨,以产生含有反应性有机材料的基本上不含氨的液体,其被冷却并置于含有厌氧细菌的蒸煮器中,以将液体中的反应性有机物质转化为沼气并产生蒸煮器 液体。 将沼气抽出并用于发电,少量的蒸煮器液体从蒸煮器中排出并循环回混合容器。 在此过程中除去的水不溶性固体和氨可分别转化为反刍动物饲料和浓缩液体肥料。

    • This invention is a sharpening device for lawn edger blades. The device is specifically designed for attachment to the machine and in use for when the machine is in operation. The reason for this is to keep the cutting edge of the blade continually sharp. The attachment is positioned near the cutting edge and sharpens the blade as it rotates. A manual switch or lever activates the sharpener as the user desires. The sharpener includes a caliper with an abrasive surface to squeeze against the rotating blade while the edger is in operation.
    • 本发明是用于草坪修边刀片的磨刀装置。 该设备专门设计用于机器附件和机器运行时的使用。 这样做的原因是保持刀片的刀刃不断锋利。 附件定位在切割边缘附近,并在刀片旋转时锐化刀片。 手动开关或手柄根据用户的需要激活磨刀机。 磨刀器包括具有研磨表面的卡钳,以在磨边机运行时挤压旋转刀片。
