A grow light fixture that may be used for the replacement of high intensity discharge (HID) lamp fixtures used for growing plants includes a housing containing a plurality of both red and blue high power LEDs mounted to a circuit board, and powered by an onboard power supply. Control circuitry may include separate, infinitely variable controls to enable independent adjustment of the red and blue LED light output. A plurality of thermal vias made of copper or other thermally conductive material extend through the circuit board to conduct heat from the LEDs to a heat sink mounted on the back of the circuit board, and a fan may be used to vent the heat to the outside of the housing. The housing is mounted an appropriate distance above a plant in a growth media to provide user-controlled lighting for enhanced plant growth.

An overrunning coupling assembly includes a notch plate and an annular coupling pocket plate positioned in face-to-face relationship with respect to each other along a common axis. The pocket plate has strut pockets disposed at angularly spaced positions about the common axis. The notch plate has notch recesses at angularly spaced positions about the common axis and positioned in juxtaposed relationship with respect to the strut pockets. Torque-transmitting struts are positioned in each of the strut pockets. Each strut has first and second ears at one edge thereof for enabling pivotal motion of the struts about an ear axis intersecting the ears. The opposite edge of each strut is movable between disengaged and engaged positions with respect to one of the notch recesses whereby one-way torque transfer may occur between the plates. A lubricant flows between the notch plate and pocket plate. A spring is positioned in each strut pocket and biases the respective strut toward the notch plate. Each spring engages the respective strut intermediate the ear axis and the opposite edge. Each strut pocket provides sufficient clearance forward of the respective opposite edge of the strut to allow forward sliding movement of the respective strut during overrunning to cause the engagement of the respective spring and strut to occur nearer the ear axis, thereby reducing the length of a moment arm about which the spring acts upon the strut which enables frictional forces of the flowing lubricant to hold the strut in its disengaged position to prevent the strut from slapping against the notch recesses as the notch plate and pocket plate are respectively counterrotated.

An acoustical and thermally absorbent chopped strand mat formed of thermoplastic bonding materials and bundles of reinforcing fibers is provided. The reinforcing fibers are preferably wet use chopped strand glass fibers (WUCS). The thermoplastic bonding materials may be any thermoplastic or thermosetting material having a melting point less than the reinforcing fiber. The chopped strand mat may be formed by partially opening the WUCS fibers and filamentizing the thermoplastic bonding materials, blending the reinforcement and thermoplastic bonding fibers, forming the reinforcement and thermoplastic bonding fibers into a sheet, and bonding the sheet. During bonding, the sheet is heated to a temperature above the melting point of the thermoplastic bonding fibers but below the temperature of the glass fibers. The melted thermoplastic bonding fibers act as a glue to hold the glass fibers in bundles. The chopped strand mat thus formed may be used as a reinforcement material in automotive applications.

Existing plate-type heat exchangers typically include plates that are constructed of metal or paper, which are only capable of transferring a limited amount of moisture, if any, from one side of the plate to the other side. The present invention is a plate-type heat exchanger wherein the plates are constructed of ionomer membranes, such as sulfonated or carboxylated polymer membranes, which are capable of transferring a significant amount of moisture from one side of the membrane to the other side. Incorporating such ionomer membranes into a plate-type heat exchanger provides the heat exchanger with the ability to transfer a large percentage of the available latent heat in one air stream to the other air streams. The ionomer membrane plates are, therefore, more efficient at transferring latent heat than plates constructed of metal or paper.
