Abstract: A device for separating magnetic particles from a fluid stream including an enclosure, an inlet and an outlet conduit communicating with the top portions of the enclosure, and a baffle interposed therebetween causing fluids passing from the inlet to the outlet to traverse to a lowermost portion of the enclosure, in proximate location to a magnetic source whereby the intimate contact thereon causes magnetic particles entrained in the fluid to be removed.

Abstract: A water power unit for a dam which includes a downwardly directed conduit for directing water from the body of water from the body of water retained by the dam to a water turbine or the like for generating power, the conduit including an upstanding U-shaped section having a bight portion extending above the level of the body of water together with a pump for pumping water entering the conduit around a check valve in the conduit to initially fill the conduit U-shaped section with water so that an increase is obtained as water flows in the conduit to increase the power output of the turbine together with a siphon action obtained within the U-shaped section during the operation of the turbine for further power increase.
