Abstract:
A goose neck style vent has a base that registers with a surface opening of a building, and upstanding walls which form a portion of a curved air flow pathway above the vent opening. A top portion of the vent registers with the base to complete the curved air flow pathway and define an air outlet opening. The top includes a screen that hinges to cover the air outlet opening. A flapper valve is positioned across the curved air flow pathway and is hinged to the base at one end. The opposite free end of the flapper valve is urged to a closed position by gravity and to an open position by air pressure from below. An upstanding air deflecting baffle extends above the free end of the flapper, and limits air gusts passing through the screen and under the free end of the flapper valve.
Abstract:
A hand held vacuum cleaner unit and docking assembly for a central vacuum system is shown. The hand held vacuum cleaner has a handle, a suction nozzle, a trigger switch to turn on a battery powered suction motor and an outlet port. The docking assembly fits into a central vacuum cleaner mounting plate, and provides a cradle to store the hand held vacuum cleaner. Recharging contacts, a latch mechanism, seals and an intake port are provided on the docking assembly. When the hand held unit is in the docking assembly it may be electrically charged, and emptied of dirt and debris by activation of the central vacuum system. The docking assembly also includes an access port for a conventional central vacuum hose.
Abstract:
The present invention relates to a grease trap system for wastewater systems, having an inlet pipe with a shut off valve, an outlet pipe with a shut off valve and a grease interceptor comprising a replaceable container body including means to trap fats, oils and grease within the body. The body has inlet and outlet slide couplers in opposed walls, and each coupler has an associated connecting means to sealingly fluidly connect the slide couplers to the inlet and outlet pipes. When the container body is disconnected from the pipes the slide couplers may also be sealed by a removable plug for transport. The slide couplers displace inwardly and outwardly relative to the container to give clearance between the pipes to remove the container. A method of replacing full containers with empty containers is also comprehended.
Abstract:
A normally open backwater prevention valve for connecting to a sanitary drainpipe. The valve has an inflow end to connect to an upstream part of the drainpipe, and an out-flow end to connect to a downstream part of the drainpipe. There is a main body defining a flow through chamber extending between the inflow and the out-flow ends and a valve seat formed on an upstream side of the main body which faces downstream. A float assembly having opposed floats on opposite sides of the flow through chamber has a check valve assembly including at least a valve member located between the opposed floats. The valve member is sized and shaped to seal on the valve seat, and is operatively connected to the float assembly through a gear box. When the floats are down the valve member is in an open position and when the floats are up the valve member is moved to a closed position on the valve seat. Also provided is an access opening on a top of the flow through chamber, and a removable cover for sealing the access opening.

Abstract:
An adaptor for a passive roof vent is presented having a base securable to a roof deck and an integrally moulded stepped collar extending from the base on one side for connecting to different air duct sizes which defines a discharge end for an air flow passageway. A central well is defined by the collar adjacent to and below the base and is open towards the other side of the base and has a hinge pin for at least one flapper valve retained in the well below the base. At least one flapper valve, hinged to the hinge pin, pivots about a closed position to which the flapper valve is biased by gravity and an open position in which the flapper valve is opened by air pressure from below within the air flow passageway. The flapper valve remains partially within the well when the flapper valve is open.
Abstract:
A ridge vent for venting air through a ridge opening of a roof. The ridge vent has an elongated body having spaced apart outer attachment flanges to partially extend down a sloped roof deck on either side of the ridge opening a top surface on said elongated body extending between and connecting the outer flanges. It also has upwardly facing ventilation openings formed a top of the elongated body to permit air to vent though the body; and at least one weather deflecting baffle extending below the upwardly facing ventilation openings to deflect water passing through the ventilation openings away from the ridge opening and onto the roof deck adjacent to and below the ridge opening. A method of installing the vent is also shown.
Abstract:
A female electrical receptacle for mounting behind an inlet valve of a central vacuum cleaning system, having a base portion and a cover portion wherein the base portion defines three open topped channels and two side channels include an electrically conductive bayonet extending into said channel. The central channel retains the ground wire. Each bayonet is electrically connected to a female pin receptacle located toward one end of said base portion. The cover is sized and shaped to be field securable to said base portion to close said open top channels onto said bayonets, The female electrical receptacle further includes attachment features adjacent the pin receptacles, which are sized and shaped to engage with said inlet valve to permit said one end to be mounted behind said inlet valve and connected to a plug opening in said inlet valve. An electrical wire may be field inserted between the cover and the base so that when the cover is secured to the base an electrical connection is completed by the bayonets between the wire and the pin receptacles to electrify the plug opening in the inlet valve.

Abstract:
A bathtub drain and overflow fitting kit is provided having a drain fitting, an overflow fitting and/or an adapter fitting, for connecting the bathtub drain and overflow openings to the household waste plumbing. The overflow fitting has a ball and socket connection between its inlet and outlet. Preferably, the overflow fitting has an abutment member which limits the range of angles created by the joint socket and joint ball within a range of angles to about 10°. The kit includes a gasket having a first sealing portion, a second sealing portion, and a tapered sealing portion between the first and second sealing portions, and is configured so that the same gasket may be used at the drain opening or the overflow opening. The drain and overflow fittings have at their inlets retaining features that interengage matching retaining features on the gasket to hold during installation.
