Disclosed is an electrical box extension that includes an extending member for switch and/or plug mounting having one or more fastening brackets, one or more base fastening brackets and one or more fasteners that together with optional contact points provide for mechanical and electrical connectivity between the extending member and its associated electrical box and provide sufficient mechanical resistance to support the adjustable elevation of the elevating member thereby supporting a flush surface for surface mounted sockets, switches and their associated plates.

A containment assembly for use with a pressure washing apparatus to contain and collect the relatively light weight contaminants from run-off of a washing fluid after being flowed over an object to be cleaned. The containment assembly includes a settling compartment for collection of the run-off washing fluid therein, and a containment compartment in gravity flow fluid communication with a surface of the collected washing fluid in the settling compartment. As the lightweight contaminants at the surface of the washing fluids gravity flow into the containment compartment, they are contained and collected therein. A fluid extraction assembly is in fluid communication with the contained washing fluid in the containment compartment through an opening therein vertically disposed below a predetermined operational fluid level of the contained washing fluid. The extraction assembly is adapted to extraction the contained washing fluid through the opening in a manner maintaining the gravity flow of the collected washing fluid into the containment compartment.

Several products and processes for preventing the occurrence of rust stains resulting from irrigation systems using water having iron ions, such as well water, and for cleaning off rust stains resulting from the use of said irrigation systems are disclosed. In one embodiment, ammonium sulfate is mixed with well water and then this mixture is mixed with incoming well water being sprayed on the surfaces. In another embodiment, ammonium bisulfate is used for the removal of rust stains. Then ammonium sulfate is mixed with the incoming well water being sprayed in the next cycle, to prevent rust formation.
摘要:
Agents are used as cleaning agents and also as agents to purify the water in water treatment plants. The agents are a mixture of phosphates and fatty acid salts. Precipitation agents are used such as, polyvalent metals. The pH is adjusted. Flocking agents can be used to increase the rate of separation. The purified water is removed after precipitation.

An ion exchange process for treating waste water having caustic materials, uses a bed of cation exchange resin beads to which the waste water is added. Thereafter the bed of beads is allowed to absorb the caustic materials in a brine until the resin is exhausted. The bed having retained organic matter is regenerated by rinsing the bed with water to remove substantially all the organic matter; draining any remaining rinse water; adding water and allowing it to pass through the bed and exit therefrom; mixing the exiting water with acid to form a dilute acid; and adding this dilute acid to the bed until the water exiting the bed has substantially the same pH as the dilute acid entering the bed.
摘要:
In a battery post burning apparatus, the majority of the heat is supplied to the lead via the mold in which the finished post is being formed. The mold material in contact with the lead has a low thermal mass and high electrical and thermal resistance.The mold material may be Meehanite cast iron. Another material, such as titanium, may be used. If so, it is preferable to coat it with silver solder and provide a copper insert, where the electrical and thermal connection is being made.In another embodiment, a magnetic field is provided to break up any oxide coatings on the mold surfaces.
