Abstract: A fire escape device includes a housing having a top wall, a first end wall, a second end wall, a front wall and a rear wall. A spindle is rotatably mounted to and extends between the first and second end walls. A pair of gripping members each has a bottom side, an upper side, and a pair of lateral sides. The spindle extends through each of the lateral sides such that the bottom sides are positioned nearer the spindle than the upper sides. A spool with a tether is rotatably mounted on the spindle. The tether has a free end extending through an aperture in the top wall. A fastening assembly is attached to the free end for selectively attaching the free end to a dwelling. Hands positioned on the gripping member are secured within the housing by a compressing action between the gripping member and the front wall.

Abstract: A system for processing water by adding an additive to a stream of pressurized fluid. The system comprises first and second bodies. The first body defines a main passageway having a main inlet and a main outlet. The stream of pressurized fluid enters the main passageway through the main inlet. The second body is secured to the first body. The second body defines an additive passageway having an additive port. The additive passageway is in fluid communication with the main passageway at an injection location. Fluid flowing through the system creates low pressure that draws the additive through the additive port and the additive passageway and into the stream of pressurized fluid.

Abstract: A system for processing water by mixing the water with an additive. The system comprises a source of unprocessed water; a destination of processed water; a source of the additive; structure defining a main passageway, a bypass passageway, and an injection passageway. The bypass passageway is in fluid communication with the main passageway at first and second locations. The injection passageway is in fluid communication with an injection portion of the bypass passageway. The injection portion of the bypass passageway is configured such that the flow of unprocessed water through the bypass passageway causes additive to flow through the injection passageway and into the bypass passageway. The system may further comprise optional structure for creating a differential pressure between an inlet portion of the main passageway and a mixing portion of the main passageway.
