Publication number: 20060098359Abstract: A submersible motor having electrical-surge protection. The submersible motor includes a motor housing formed from an electrically-conductive material; a stator-winding assembly disposed within, and electrically insulated from the motor housing; a power wire for transmitting electrical energy delivered by an external power source to the stator-winding assembly within the housing; and an end ring formed from an electrically-conductive material. The submersible motor further includes a surge-protection assembly having a surge protector that includes two opposing electrode surfaces that are held a distance apart by an insulator and a coupling member formed from an electrically-insulating material. The coupling member abuts the power wire against the surge-protection assembly to establish an electrically-conductive path between the power wire and the surge-protection that is substantially devoid of wires.Type: ApplicationFiled: November 9, 2004Publication date: May 11, 2006Inventor: Jack Bevington

Patent number: 6413053Abstract: A method of supplying water from a well is provided. The method includes the following steps. First, a supply apparatus is provided that includes a container having first and second ends and a first chamber extending to a first opening in the second end. The supply apparatus also has a first fluid conduit with a first branch for use in transporting the water from the first chamber. Next, at least a portion of the second end of the container is submerged within the water in the well such that the first chamber contains a quantity of air. Then, at least a portion of the quantity of air from the first chamber is removed by an air compressor thereby drawing a vacuum within the first chamber. The vacuum in turn draws a quantity of water from the well into the first chamber through the first opening. Next, the removal of air from the first chamber is stopped when the water has obtained a first predetermined level within the first chamber. The first opening is then closed.Type: GrantFiled: February 4, 2000Date of Patent: July 2, 2002Assignee: F.E. MeyersInventor: Jack Bevington
