Abstract: A pressure driven apparatus comprising a housing, at least one flexible membrane located within the housing dividing the interior of the housing into at least two chambers. At least one input or exhaust cam assembly operates in conjunction with the at least one flexible membrane to provide an expansion zone within the housing. Fluid enters the housing producing movement of the flexible membrane. The flexible membrane is connected to a drive member such that the movement of the fluid within the expansion zone results in the membrane imparting a force to the drive member. The flexible membrane includes seals used to maintain a dynamic and movable seal with respect to the housing.

Abstract: An active cathodic protection system, the apparatus comprising a rectifier element with at least one electrical connection to a source of electrical current, the rectifier element associated with a direct current positive (+) output terminal for electrical connection of via an anode connector to a consumable anode, a direct current negative (?) output terminal for electrical connection via a cathode connector to the structure to be protected, grounding means for electrical grounding of the apparatus and anti-cross connection means for preventing the continuing flow of electrical current when the anode connector is associated with the negative output terminal and the cathode connector is associated with the positive output terminal. The cathodic protection system also includes a microprocessor controlled device for shutting the system if an improper current is sensed.

Abstract: A water treatment product comprising a mixture of at least one active ingredient and a first fluid, wherein the concentration in the product of the active ingredient is at least 50% on a weight basis and the viscosity of the product is at least 2,000 centipoise or 2 pascal seconds, the product adapted to be further diluted upon addition to a second fluid stream to be treated.
