Abstract: An LED light source with a lens is mounted to a light housing. The lens is sealed to form an encapsulated atmosphere about the LED. The housing has a cylinder and a divider between the cylinder and the LED. A slidable and sealed piston in the cylinder creates an air chamber between its upper surface and the divider and a lower surface of the piston is exposed to air pressure of the outer atmosphere. A conduit is formed through the divider to interconnect the encapsulated atmosphere with the air chamber in the cylinder. LED heat causes the pressure of the encapsulated atmosphere to increase, and it flows through the conduit to press against the piston. This piston slides to create a larger air chamber to equal the increased pressure of the encapsulated atmosphere to the pressure of the outside atmosphere. The reverse occurs when the LED cools.

Abstract: A wiring system for ground mounted lighting fixtures comprises a base of the lighting fixture that is located on top of the ground surface. The above-ground base includes a wiring box and construction of the base resists sprinkler water and rain from entering the wiring box. A connector device is mounted in the wiring box and has multiple ports for interconnecting the wires of the incoming power cable with wires of the outgoing power cable and interconnecting those wires with the wires of the power cable of the light source in the fixture. The connector device includes an internal circuit that provides a parallel connection of the light source cable with the incoming and outgoing power cables. Spring lever clamps are used to secure the various wires in the connector device ports and in connection with the internal circuit. The wiring box is thus integral with the light fixture.

Abstract: An LED light unit which creates an air movement over a metal surface by way of convection. This keeps the LED unit significantly cooler than with just fins alone. This is accomplished by the design of a lamp. The LED chip transfers the heat to the metal surface and the hot air near that metal rises and starts a flow through channels designed into the lamp. This brings in cooler air over the metal surface in a directed method by convection to achieve better cooling of the LED chip area.

Abstract: An alert alarm responsive to the passage of a child unaccompanied by an adult. An adult sensor is placed at an adult height higher than any anticipated child. A child sensor is placed at a height lower than the height of the shortest anticipated child. Actuator circuitry is actuated if a child passes the child sensor unless an adult passed the adult sensor within a limited time either before or after the child passed.

Abstract: A purge line to return cooled water in a hot water line directly to a cold water line to avoid wasting water by draining the cooled water while awaiting arrival of hot water at a hot water outlet valve. The purge line is connected in near adjacency to a hot water outlet valve to minimize the amount of cooled water still in the hot water line between the purge line and the valve.

Abstract: A motor mounting means for a centrifugal coolant pump having its own cooling fans has a housing provided with a supporting surface therein for supporting a motor and flanges extending from one interior wall which index a motor and restrain the motor against rotational movement. A cap is secured to the housing by bolts extending through lugs located on the outside of the housing and into posts in the cap so that the size of the cooling fan is maximized. Index vanes within the cap position the cap and abut against a topside of the motor to secure the motor against the supporting surface.

Abstract: A switch housing for a control device which includes both automatically thermally operable and manually operable switches. The housing is adapted to be positioned on a wall or other surface and can be secured to a single or double electrical junction wall box. The housing includes an integral mounting bracket to support one or more switches outwardly of a base panel, and a supporting bracket to support a bimetallic element. A cover is provided to enclose the housing and includes apertures through which the several switches and controls can extend.
