Abstract: The mixing and feeding apparatus comprises a frame on which is mounted a polymer delivering pump and a water delivering mechanism. The frame also supports a mixer which includes a vessel for receiving the polymer and the water. The impeller mechanism includes four fins at right angles rotatably mounted in the vessel for mixing the water and the concentrated polymer into low shear, high torque conditions.

Abstract: An exercise pool for animals having an entry thereto and an exit therefrom with a hollow island mounted centrally thereof and extending upwardly therefrom, a filtering area and a solids pit in the island with a screen disposed therebetween, a skimming gutter at the upper end of the island having an inlet at the surface of the pool of water and an outlet to the solids pit, a pump for pumping water from the pool through the solids pit and the filtering area and back into the pool through the lower portion of the island, water filtering mechanism in the filtering area for filtering the current of water flowing therethrough, water treatment mechanism for treating the water flowing through the island to maintain the chlorine content and the pH thereof within predetermined limits, and a main drain in the lower portion of the island to draw water from the pool and upwardly to the solids pit when the water level within the island falls to a predetermined level; there also is disclosed a self-contained island for moun

Abstract: An aquatic exercise facility for animals including a pool of water having an animal entry area and an animal exit area in alignment with a portion of the pool therebetween of a depth sufficient to require the animal to swim thereacross, mechanism for pumping water to establish a current from the animal exit area toward the animal entry area, the pumping mechanism having an inlet and an outlet for water thereto and a control for controlling the amount of water pumped thereby, a return channel for water disposed on either side of the pool for returning water from the animal entry area to the inlet to the pumping mechanism, and adjustable flow control structure disposed between the deep portion of the pool and the return channels for adjusting the rate of flow of water therebetween; also disclosed are directing vanes at the outlets from the pumping mechanism to direct the current to provide a higher velocity along the sides of the pool than in the middle thereof; there further is disclosed an improved water filt
