Abstract: A faucet in which water is discharged by electrical actuation only and water temperature is controlled manually comprises a housing for connection to a water supply and a discharge spout. At least two inlets are formed in the housing for connection to hot and cold water supplies, and at least one outlet is formed in the housing for connection to the discharge spout. A single flow control valve mechanism is movable in a first direction to establish a flow path between the inlets and outlets or to block flow between the inlets and outlets, and in a second direction to expose the flow path to a desirable mix of hot and cold water from the hot and cold water supplies. An electrical actuation mechanism moves the valve mechanism in the first direction and a manual temperature control mechanism moves the valve mechanism in a second direction. The electrical actuation and manual temperature control mechanisms operate the valve mechanism independently of each other.

Abstract: A faucet for discharging water automatically or manually includes a body which supports a single flow control valve mechanism, a manual actuation mechanism which operates the flow control valve mechanism, and an electrical actuation mechanism which operates the flow control valve mechanism independently of the automatic actuation mechanism. The faucet may be centrally mounted behind two adjacent sink bowls and positionable over each of the bowls to discharge water. Electrical detection means mounted behind one of the bowls detects the presence of a user of that bowl and automatically actuates the faucet in response thereto.

Abstract: A water faucet for discharging water automatically or manually includes a body which supports a single flow control valve mechanism, a manual actuation mechanism operatively associated with the flow control valve mechanism to operate the flow control valve mechanism and an electrically operated automatic actuation mechanism operatively associated with the flow control valve mechanism to operate the flow control valve mechanism independently of the manual actuation mechanism.

Abstract: An automatic hand dryer contains a heating element and a motor which drives a squirrel cage fan. The fan exhausts air past the heating element to a downwardly-directed outlet. A base or mounting plate is adapted for flush mounting to a wall. The axis of the fan is peripendicular to the base plate and wall to which the dryer is attached. A control or sensing circuit emits signals to a detection zone beneath the outlet and monitors the zone for reflected signals indicative of a user's presence. The circuit operates to energize and deenergize the power circuit to the fan motor and heating element. Upon detection for a predetermined period, the circuit energizes the power circuit. The control circuit deenergizes the power circuit upon interruption of the reflected signals for a predetermined period, or after a predetermined maxium time period of continuous detection. Under the latter condition, the stimulus reflecting the emitted signals must be removed from the detection zone to reactivate the control circuitry.

Abstract: A water spray head for a shower or sink includes means for emitting and receiving signals for automatic operation in response to the presence of a user. The means are positioned such that the stream of water surrounds the emitting and receiving means. The emitting and receiving means includes conduit means disposed within at least a portion of water supply connected to the spray head. In one embodiment, the conduit is in the form of a fiber optic cable. In another, an emitter and detector are mounted in the spray head and the conduit comprises electrical conductors.

Abstract: An electrically operable liquid soap dispenser responsive to the presence of a user dispenses a measured amount of soap on demand. It has a spout with a fluid conduit therein connecting a soap reservoir and a nozzle. A pump draws soap from the reservoir during a stroke of its plunger and depending on the embodiment, ejects a measured amount of soap during a subsequent plunger downstroke or upstroke. At least one check valve regulates the flow of soap from the reservoir to an orifice at the nozzle. The soap path from the reservoir to the nozzle is kept full of soap so that a single cycle of the pump is sufficient to eject the desired amount of soap. The orifice is sized and shaped so as to prevent dripping while maintaining soap at the nozzle ready to be ejected. A light beam emitter and detector control operation of the pump.

Abstract: An automatic hand dryer contains a heating element and a motor which drives a squirrel cage fan. The fan exhausts air past the heating element to a downwardly-directed outlet. A base or mounting plate is adapted for flush mounting to a wall. The axis of the fan is perpendicular to the base plate and wall to which the dryer is attached. A control or sensing circuit emits signals to a detection zone beneath the outlet and monitors the zone for reflected signals indicative of a user's presence. The circuit operates to energize and deenergize the power circuit to the fan motor and heating element. Upon detection for a predetermined period, the circuit energizes the power circuit. The control circuit deenergizes the power circuit upon interruption of the reflected signals for a predetermined period, or after a predetermined maximum time period of continuous detection. Under the latter condition, the stimulus reflecting the emitted signals must be removed from the detection zone to reactivate the control circuitry.

Abstract: An anti-rotation device for mounting on a faucet shank on the underside of a basin has a cylindrical body adapted to be keyed to the shank. A pair of diametrically opposed, outwardly directed webs extend from the spacer body. Each includes an adjustable abutment rod threaded to the web for adjusting its length. Free ends of the abutment arms are adapted for engagement with an associated planar surface such as a wall to resist rotation of the spacer body, and, thus, the faucet shank.

Abstract: A flow-control valve including a separable body and fitting which define a cavity to house a seal assembly having a rotatable seal member with flow ports and a stationary seal member with corresponding flow ports. The rotatable seal member is selectively positionable by means outside the body to position the flow ports into or out of alignment to regulate or shut-off the flow of fluid, as desired.

Abstract: A filtered stop including a seal assembly having a rotary seal member with flow ports and a stationary seal member with corresponding flow ports, the rotary seal member being selectively positionable by indexing means which are operable from outside the stop so that the flow ports of the rotary seal member may be positioned either into or out of alignment with the ports of the stationary seal member to automatically shut off the flow of fluid before removal of the filter can be accomplished.

Abstract: A sewage treatment apparatus for use in a toilet room comprises a casing with an inlet for reception of sewage and a discharge outlet. There are means within a chamber in the casing for the chemical treatment and agitation of the sewage to reduce the sewage to a substantially sterile slurry. There is a series of valves within the casing to control the passage of the sewage after it has been treated to be directly discharged through the casing outlet, or optionally discharged to a connected, remotely located holding tank.

Abstract: A pinch valve includes a distortable rubber-like valve member, in cylindrical form, positioned within a generally cylindrical housing. The valve member has uniformly spaced projections and grooves which enable the valve member to collapse upon itself forming a complete closure between opposite ends thereof. When the valve member so collapses, the circle defined by the outer areas thereof has a greater radius than the radius of the valve member in the uncollapsed condition. The housing has lobular areas to accommodate the extensions of the collapsed valve member.

Abstract: A sewage treatment apparatus comprises a casing with an inlet for reception of sewage and a discharge outlet. There are means within the casing for electrolytically treating the sewage therein and there are means for agitating sewage within the casing. There is a valve at the discharge outlet and means for operating the valve to control the passage of sewage after it has been treated by agitation and electrolysis.
