摘要： A guide bar is detachably clamped to the panel being cut with a pair of guide plates extending therefrom and registering upon the line to be cut. The guide bar is provided with a longitudinally extending slot or groove into which is engageable a guide block for longitudinal movement therealong. A power saw is detachably securable to the guide block which guides the saw blade along the line to be cut. The guide bar includes an underside clamp and spacer bar which spaces the panel above the supporting surface sufficient to give clearance to the underside of the saw blade as the panel is being cut.

摘要： The invention is a process and an apparatus for removing metal contamination from soil. In the method, the soil is treated to produce soil with a small particle size. The particulate soil is then separated into a coarse fraction and a fine fraction. The coarse fraction and the fine fraction are contacted with a leach solution in separate contacting zones to remove the metal contamination from the soil, the metal is removed from the leach solution and the leach solution recycled to the leaching zones.
摘要翻译：本发明是一种从土壤中去除金属污染的工艺和设备。在该方法中，土壤被处理以产生具有小粒径的土壤。然后将颗粒状土壤分离成粗级分和精馏。粗级分和细级分与独立接触区中的浸出溶液接触以除去来自土壤的金属污染物，将金属从浸出溶液中除去，并将浸出溶液再循环至浸出区。

摘要： The invention is an apparatus and process for recovering metal from a solution. This apparatus is a structure having an anode formed from a plurality of reducing metal elements and a cathode formed from a high surface area electrically conductive material such as metal wire. The reducing metal elements of the anode have a more negative standard state reduction potential than the metal to be recovered. This invention is also a process in which a metal is recovered by contacting a solution of a metal to be recovered with the apparatus of the invention.
摘要翻译：本发明是从溶液中回收金属的装置和方法。该装置是具有由多个还原金属元件形成的阳极和由诸如金属线的高表面积导电材料形成的阴极的结构。阳极的还原金属元素比待回收的金属具有更负的标准状态还原电位。本发明也是通过使待回收的金属溶液与本发明的装置接触来回收金属的方法。
