摘要： A new covered landfill or remediated waste containment cell having an excavated bottom surface, lined with a watertight liner and a leak detection system for determining whether or not leakage has occurred, either from the top, or from the bottom. The cover over the landfill containment cell substantially prevents rainwater from coming in the top, and the liner stops water from erupting up from the bottom. This containment cell allows a method of storing waste in an essentially non-contaminating manner, thereby providing an environmentally sound procedure and apparatus for storing toxic wastes. This containment cell is particularly suitable for remediating old leaking landfill sites within a short distance of the old site.

摘要： A light duty electric reciprocating handsaw includes a body assembly having a throat therein, a removably and reciprocally attached saw blade within the body assembly spanning the opening of the throat so that any workpiece that fits inside the throat can be cut across its width. The handsaw is either electrically or battery operated and includes an electric motor mounted within the body assembly, the weight of the motor being generally distributed over the saw blade. Preferably, the throat of the body assembly is generally defined by an upside down U-shaped configuration for receiving the workpiece therein after cutting with the saw blade. A balance of the weight is located generally over the saw blade, with the remainder of the weight of the unit being distributed generally evenly throughout the rest of the handsaw such that the operator will experience an aid in cutting the workpiece through the force of gravity. A a reciprocating handsaw holder in accordance with the invention includes a bracket for receiving the reciprocating handsaw which is pivotally and slidably mounted to a base which further includes a workpiece assembly support to hold the workpiece in place while the reciprocating handsaw is in operation.
摘要翻译：轻型电动往复式手锯包括其中具有喉部的主体组件，在主体组件内跨过喉部开口的可移除和往复连接的锯片，使得适合于喉部内部的任何工件可以横切其宽度。手锯是电气或电池操作的，并且包括安装在主体组件内的电动马达，电动机的重量通常分布在锯片上。优选地，主体组件的喉部通常由倒置的U形构造限定，用于在用锯片切割之后接收工件。重量的平衡通常位于锯片上，其中单元的重量的其余部分大致均匀地分布在手柄的其余部分中，使得操作者将经历借助于重力来切割工件的辅助。根据本发明的往复式手持式保持器包括用于接收往复式手锯的支架，其可枢转地和可滑动地安装到基座，该基座还包括工件组件支撑件，以在往复式手锯工作时将工件保持在适当位置。
