摘要:
A manually manipulable tool movable along a linear index to create a trench for planting seeds at a spaced distance from the index. The depth of the trench and its spacing from an index are adjustably variable. The device may be indexed from either side and may create an additional indexing indicia at a spaced distance from the seed trench created.

A hygienic unit is provided for delivering water at a controlled temperature to a nozzle which provides a jet or stream of water which can be applied by a person for cleansing or sanitary purposes to any part, organ, or cavity of the body. The unit includes a manual adjusting knob for initially setting a thermostatic motor which cooperates with a valve assembly for controlling a flow of hot water for mixing with a flow of cold water such as to provide a mixed flow of water having a selected temperature. The thermostatic motor then provides for repositioning the valve assembly as required to maintain the selected temperature of the mixed water being delivered by the hygienic unit.

A series of flat templates, each having a peripheral shape of a hole required in a wall panel, that may be releasably positioned on a utility fixture to be serviced by the hole. The panel facing side of each template is provided with an adhesive so that if a wall panel that is ultimately to define a hole to service a utility fixture is positioned against the template it will releasably adhere to the panel to determine position and configuration of the hole to be established. The template adhesive is of a form that may be reused and replaced.
摘要:
A method and apparatus for remediating wastewater holding areas and the like includes a closed, foraminous dewatering membrane that is positioned adjacent to the wastewater holding area. Sludge and adjacent water on the bottom of the wastewater holding area are pumped in the form of a sludge slurry into the interior of the dewatering membrane. The water is removed from the sludge slurry by allowing gravitational forces to flow water through the dewatering membrane. The dewatering membrane is then opened, and the dewatered sludge is removed for depositing at an appropriate site.
