Abstract: A main drain system for use in a swimming pool installation including a swimming pool and a recirculating system. The recirculating system includes a skimmer device coupled to a pump and a filter assembly for recirculating the water in the swimming pool. The main drain system includes a vacuum module mounted adjacent the swimming pool, a conduit coupling the vacuum module to the pump, and a conduit coupling the vacuum module to the main drain.

Abstract: A vacuum system for use in a swimming pool installation including a swimming pool and a recirculating system. The recirculating system includes a skimmer device and a main drain coupled to a pump and a filter assembly for recirculating the water in the swimming pool. The vacuum system includes a vacuum module mounted adjacent the swimming pool, a conduit coupling the vacuum module to the pump, and a hose coupling extending from the vacuum module in liquid communication with the swimming pool, the hose coupling adapted to receive a vacuum hose.

Abstract: A glass guidance component having an injection molded thermoplastic chassis integrally bonded to a fabric interface during the molding process. The chassis is a thermoplastic polymer formed by injecting the thermoplastic into a mold in which the fabric interface is predisposed. During the injection and setting of the thermoplastic chassis, the fabric integrally bonds to the chassis. The fabric interface is disposed at locations which contact a glass panel and may include a pile material.

Abstract: A bait station for rodents, an elongate, hollow tubular structure having a single opening to and from its interior. This station is formed of tubing fabricated, preferably, of tough, corrosion, weather and distortion resistant plastic such as a polyvinylchloride. Its preferred configuration provides that one end portion of its tubular structure is enlarged as to its cross sectional area to define a bait chamber the entrance to and exit from which is limited to a single passage, defined by its remaining length the remote end of which provides the single opening to and exit from the passage. The cross sectional area of said passage is made substantially less than that of said chamber. This precludes entrance by animals larger than that of the target rodents. Preferred bait embodies a non-poisonous anti-coagulant, ingestion of which produces a breakdown of the rodent's life support system and its expiration, but not until some time after the rodent leaves the vicinity of the bait station.
