Abstract: A filtration system is provided for a dry well in the form of a buffer tank made of concrete to remove sediment and pollutants from water supplied from a header to an inlet pipe in the tank, so that the water exiting from an outlet pipe is free of particulate matter and pollutants. This is accomplished by providing a sediment pit and a baffle at the inlet side of the tank and then passing the water through a multiple stage set of filters having different aperture sizes. These filters remove particles and pollutants from the water as it passes through the buffer tank on its way to a dry well drain pipe attached to the outlet of the buffer tank.

Abstract: A retaining ring of an eyeball return fitting of the type used in swimming pools and spas is provided with a releasable or breakaway cover cap. The cap closes the end of the return fitting during construction. This permits the finish work for the cement and plaster stages of the pool construction to be effected without the danger of cement or plaster getting into the fitting during construction. After construction has been completed, the cap is released and drops away, carrying with it any cement or plaster which may have hardened on it during construction.

Abstract: A fitting and faceplate cap assembly, for use in swimming pools, and the like, with vinyl liners, comprises a fitting member which extends through an opening in the wall of the pool with a flange overlying the opening on the inner surface of the pool. The fitting is hollow to adapt it for connection to water return lines or drain lines commonly used in such swimming pools. The flange on the fitting has a circular groove formed in it with a pair of enlarged recesses extending from the groove on opposite sides of the opening through the fitting. The faceplate cap includes a circular ridge with a pair of spaced projections for matingly engaging the groove and recesses in the faceplate of the fitting. A gasket is attached to the inner surface of the faceplate cap. This gasket has a tacky adhesive on the exposed surface which faces the flange so that when the cap is pressed into place over a vinyl liner (installed in a conventional manner) to engage the groove in the flange, the tacky adhesive on the gasket engages and holds the vinyl liner in place. The cap and fitting are subsequently pressed tightly together by means of a threaded insert in the common opening of the fitting and cap.

Abstract: A perimeter monitoring system is arranged to detect passage across a perimeter of an area. The system primarily includes an emitter, a retroreflector, a detector and an alarm. The emitter provides a modulated visible laser beam. The retroreflector is arranged to direct the beam along a segment of the perimeter and return the beam along the segment. The detector includes a device that blocks reception of light outside an angle of less than 5 degrees. One or more local or remote alarms are activated in response to the signal. For example, a remote alarm is located on the inside of a residence window where it is activated by another visible laser beam. Alignment of the peripheral monitoring system is less costly and false alarms are less likely than with known systems.

Abstract: A pop-up cleaner for a swimming pool. The gear housing of the cleaner is removably positioned in a fitting in a circular opening in the floor of the pool. A jet block is mounted on a linear movable hollow tube that rotates with a rotor mounted in the gear housing, which rotor is connected through a reduction gear train mounted in the gear housing to an impeller mounted in a turbine casing on the gear housing. The fitting is adapted to be connected by a conduit to a water pump. When water under pressure is present in the conduit, the jet block projects out the fitting and a stream of water under pressure is directed substantially parallel to the surface of the pool in the vicinity of the cleaner. Water flowing through the cleaner rotates an impeller which through the reduction gear rotates the jet block at a substantially constant angular velocity. When the pump is turned off, the jet block returns into the fitting.

Abstract: A replaceable rotatable therapy head is disclosed wherein the operating mechanism including an impeller and a gear train between the impeller and a ring gear on the housing is supported by a ring which is integral with the emitting nozzle and the supporting ring is held to the body of the structure by means of the flange ring also bonded to the body of the therapy head. The gear train is at the downstream end of the housing and the impeller blades are at the upstream end of the housing spaced from the gear train. A water diversion means is disposed between the gear train and the impeller blades. A friction reducing ring or the like is disposed between the support ring and the housing. The system utilizing the heads, which may be at a selected acute angle, includes aerators in the supply lines for mixing the water with air.
