Testable sealed and/or self-diagnosing electromagnetic or solid-state relays simplify troubleshooting of electrical circuits. The testable relay comprises a relay housing with terminals adapted to connect to a circuit and an opposing top wall with testable terminals formed as projections being flush with or extending from the top wall and being exposed for testing the relay by applying a multimeter device. A self-diagnosing relay comprises a relay housing with terminals adapted to connect to a circuit, and at least two light-emitting diodes (LEDs). One of the LED indicates the relay is energized, and another LED light is a diagnostic LED and indicates if the relay is damaged.

A rinse fluid valve for use in a vacuum toilet system is disclosed. The vacuum toilet system includes a waste receptacle with a rinse fluid dispenser associated therewith and a source of rinse fluid. The rinse fluid valve has a housing with an inlet in fluid communication with the rinse fluid source and an outlet in fluid communication with the rinse fluid dispenser. A flow path extends from the inlet to the outlet. A moveable rinse fluid valve member is disposed in the flow path and movable between open and closed positions. A fuse valve is also disposed in the flow path and has a normally open position to allow fluid flow therethrough. The fuse valve is actuatable to a closed position after a desired volume of fluid has passed therethrough, thereby to cease rinse fluid flow through the flow path.

A discharge valve is disclosed for use in a vacuum toilet system having a waste receptacle defining an outlet and a sewer line placeable under partial vacuum. The discharge valve comprises a housing defining an inlet and an outlet, and a rotatable discharge valve member disposed in the housing for selectively establishing fluid communication between the inlet and the outlet. A periphery of the disk valve member being formed with a series of gear teeth. An actuator is provided having a rotatable spur gear adapted to engage the periphery of the discharge valve member.

A modular vacuum toilet, and a method of servicing such a toilet, are disclosed. The toilet is used with a vacuum toilet system having a sewer line placeable under partial vacuum pressure and a source of rinse fluid. The modular vacuum toilet comprises a frame and a removable bowl engaging and supported be the frame, the bowl defining an outlet and having a rinse fluid dispenser associated therewith. The modular vacuum toilet also has a valve set module. The valve set module includes a discharge valve having an inlet in fluid communication with the bowl outlet, an outlet in fluid communication with the sewer line, and a movable discharge valve member disposed between the discharge valve inlet and outlet. A rinse fluid valve is also incorporated into the valve set module and has an inlet in fluid communication with the source of rinse fluid, an outlet in fluid communication with the rinse fluid dispenser, and a movable rinse fluid valve member disposed between the rinse fluid valve inlet and outlet. The valve set module further includes a flush control unit having a circuit board operably connected to the discharge valve and rinse fluid valve for controlling actuation of the discharge valve member and rinse fluid valve member.

A vacuum bowl assembly for use in a vacuum toilet positioned on a support surface and having a discharge valve. The vacuum bowl assembly comprises a frame having a bottom member adapted to engage the support surface, and a top member defining a shoulder. A removable bowl is provided having a flange extending about an upper edge sized to engage the shoulder, and an outlet adapted for fluid communication with the discharge valve.

A discharge valve is disclosed for use in a vacuum toilet system having a waste receptacle defining an outlet and a sewer line placeable under partial vacuum. The discharge valve comprises a housing defining an inlet and an outlet and a rotatable discharge valve member disposed in the housing for selectively establishing fluid communication between the inlet and the outlet. A periphery of the disk valve member being formed with a series of ear teeth. An actuator is provided having a rotatable spur gear adapted to engage the periphery of the discharge valve member.

A system and a method are provided for monitoring the condition of an interface. Although not limited to this particular application, the system and method are particularly suited for monitoring the interface of two liquid lubricated mechanical seal faces. The system monitors an interface by using a wave source to produce an ultrasonic shear wave, directing the wave at the interface, detecting the wave after it interacts with the interface, and comparing the detected wave to predetermined wave characteristics. Based on the comparison, an alarm may be triggered. The alarm may indicate that the mechanical seal is failing.

A rinse fluid valve for use in a vacuum toilet system is disclosed. The vacuum toilet system includes a waste receptacle with a rinse fluid dispenser associated therewith and a source of rinse fluid. The rinse fluid valve has a housing with an inlet in fluid communication with the rinse fluid source and an outlet in fluid communication with the rinse fluid dispenser. A flow path extends from the inlet to the outlet. A moveable rinse fluid valve member is disposed in the flow path and movable between open and closed positions. A fuse valve is disposed in the flow path upstream of the rinse fluid valve and has a normally open position to allow fluid flow therethrough. The fuse valve is actuatable to a closed position after a desired volume of fluid has passed therethrough, thereby to cease rinse fluid flow through the flow path.

An integrated valve set for use in a vacuum toilet system is disclosed. The vacuum toilet system includes a waste receptacle defining an outlet and having a rinse fluid nozzle, a source of rinse fluid, and a sewer line placeable under partial vacuum pressure. The integrated valve set comprises a discharge valve having an inlet in fluid communication with the waste receptacle outlet, an outlet in fluid communication with the sewer line, and a rotatable discharge valve member adapted to selectively establish fluid communication between the discharge valve inlet and discharge valve outlet. An integrally mounted rinse fluid valve has an inlet in fluid communication with the pressurized rinse fluid source, an outlet in fluid communication with the rinse fluid nozzle, and a rinse fluid valve member adapted to selectively establish fluid communication between the rinse fluid valve inlet and the rinse fluid valve outlet. An integrally mounted actuator is adapted to rotate the discharge valve member and the rinse fluid valve member. An integrally mounted flush control unit has a circuit board operably connected to the actuator to selectively drive the actuator.

A mailbox includes a body and a door pivotally attached to the body. A signal device is attached to the mailbox by a connecting member. The signal device is secured in a number of positions between the door and body of the mailbox when the door is in a closed position and the signal device is unsupported and free to fall in a downward direction by gravity when the door is opened.

An electronic module and chassis for receiving a number of such modules wherein the modules are formed with bare die chips which are directly connected to substrate and metal cover plates which form opposite sidewalls of the modules. The chassis has cooling passages which are formed by metal sidewalls that form slots into which the modules are received so that coolant can provide conduction cooling.
