摘要:
A system for fixing a substrate with a heat transferring device in an assembled orientation; the system comprising: a substantially rod-shaped positioning member having a length generally symmetrically oriented about an axis and a generally constant lateral expanse substantially perpendicular with said axis substantially along said length; said positioning member interferingly fitting within at least one of a first aperture in said substrate and a second aperture in said heat transferring device to maintain a predetermined separation between said substrate and said heat transferring device in said assembled orientation.

The present invention relates to a reservoir cover for use with hydroponic, aeroponic, aquaponic or similar systems used to cultivate plant articles without soil medium. The reservoir cover containing and re-directing water, nutrients, and other liquids, intentionally or un-intentionally leaked by the system, back into a reservoir or water source the reservoir cover is positioned upon. Within hydroponic, aeroponic, aquaponic or similar systems the plant article is held within a plant growing unit positioned above the reservoir cover. As water is dispersed from within said systems gravity directs movement of water, nutrients, and other liquids to the reservoir cover of the present invention. As water, nutrients and other liquids are leaked or lost from the plant growing unit the reservoir cover is positioned such that water, nutrients and other liquids are not dispersed to an undesirable location, but rather are re-directed back in the original water source or reservoir.

A dry sprinkler installation and sealing device for a cold environment is disclosed. The dry sprinkler installation includes a supply conduit having a first end adapted to communicate with a fire retardant fluid source and a second end supporting a sprinkler head. The supply conduit is dimensioned to extend through an opening in a wall of a cold environment, e.g., a freezer ceiling. A flexible sealing device is positioned about the supply conduit adjacent an exterior surface of the cold environment. A first end of the sealing device is secured about the supply conduit and a second end of the sealing device is secured to an exterior surface of the cold environment. The flexible sealing device allows for radial and axial adjustments to the supply conduit and sprinkler head without comprising the integrity of the sealing device.

The present invention provides a PWB having a heat sink connected to the internal circuits of the PWB that allows for heat dissipation from those internal circuits. In one aspect, the PWB includes at least two insulating layers that are coupled together and that have a conductive layer located therebetween. A conductive interconnect is located on an edge of or through the PWB and is thermally coupled to the conductive layer and a heat sink. The conductive layer forms a thermal conductive path from the conductive layer to the heat sink and thereby allows for heat to be dissipated from within an internal portion of the PWB.

A container fracturable along a break path having a generally constant wall thickness about the break path is disclosed. In order to provide a specific break path without reducing the structural integrity of the container, the body of the container is configured to concentrate stress along the break path.

A vacuum packaging machine 141 and a conveyor 17 to deliver a product package from an upstream station 140 to a position adjacent a vacuum chamber 3a. The conveyor 17 has a longitudinal direction defined by the direction of travel of the product package. The vacuum chamber has a heat sealing and cutting assembly 143 oriented transversely to the longitudinal direction of the conveyor and in a position with sufficient spacing between end walls of the vacuum chamber and the assembly 143 for the product package containing two or more products to be loaded into the vacuum chamber 3a with at least one product located in front of the heat sealing and cutting assembly and at least one other product located behind the heat sealing and cutting assembly. The heat sealing and cutting assembly 143 seals and cuts between two products to form two separate evacuated packages.
摘要:
In an insect lure and trap, a system for generating a carbon dioxide attractant has a combustion chamber in which carbon dioxide is generated by means of an exothermic reaction from a gaseous fuel rich in carbon. A container contains a pressurized supply of said fuel and a supply line connects said container to said combustion chamber. A normally closed valve is included in said supply line. The system includes means for sensing the temperature in said combustion chamber and for generating a control signal representative of said temperature. A controller responsive to said control signal compares said temperature to a reference temperature and opens said valve during selected segments of successive equal time intervals.

A dishwasher comprises a cabinet defining a wash chamber and a utensil rack mounted within the wash chamber by at least one slide. The slide comprises a track that slidably receives a wheel and includes an access opening for insertion or removal of the wheel from the track. A closure for selectively closing the access opening can prevent undesired removal of the wheel from the track. A method of removing the utensil rack comprises sliding the utensil rack to align the wheel with the access opening and lifting the utensil rack to move the wheel through the access opening.
