An electrically conductive heated glass panel assembly, control system, and method for producing panels are provided to warm objects and to insure unobstructed viewing through glass by removing moisture. An integrated connection circuit interconnects glass sheets, which have a low emissivity conductive coating deposited thereon. The circuit includes copper bus bars that are disposed onto the conductive coating through the use of a circularly rotating or an inline heating head and mask apparatus. A metallic tab, which extends from the glass sheet's peripheral edge, is disposed onto each conductive metal bus bar for external electrical connectivity. Two types of glazing channels are offered to interconnect multiple panels to external circuits and controls. A solid-state controller may be provided to obtain sensor control signals so as to drive a triac circuit that provides current flow through the panel for the desired heating.

Electrically conductive heated glass panel assembly, control system, and method for producing panels

Heating head and mask apparatus are provided for producing electrically conductive heated glass panels that may be used to warm objects or insure unobstructed viewing through glass by removing moisture. The heating head and mask apparatus utilizes either a circularly rotating or an inline heating head and mask apparatus, which deposits conductive metal bus bars into electrical contact with electrically conductive-coatings that are-disposed on the glass panels.

Heating head and mask apparatus

Methods for forming electrically conductive heated dielectric panels are provided. The panels are utilized for warming objects and/or insuring unobstructed viewing through the panels by removing moisture. The methods include depositing electrically conductive metal bus bars onto the dielectric panel, onto which panel a conductive coating has previously been disposed. The conductive metal bus bars are deposited onto the coated dielectric panel through the use of a circularly rotating or an inline heating head and mask apparatus, in combination with an oxyacetylene or a plasma device. A metallic tab, which extends from the panel peripheral edge, is brought into electrical contact with each conductive metal bus bar for external electrical connectivity.

A homogeneous sash or fenestration unit is shown which may be made of a wide variety of materials, and holds a first and a second pane of glazing material in a parallel, spaced apart, relationship without the use of spacers or a preassembled glazing unit. A novel method and apparatus for making the sash or fenestration unit may use a double door horizontal booking press with fixed or adjustable molds.

A tree stand utilized by hunters and outdoorsmen to provide an elevated view. The tree stand includes a support bracket adapted to be secured to a tree or pole, a strap for securing the support bracket to the tree or pole, a platform including a generally flat planar member for supporting at least one person; and means for releasably interlocking the platform and the support bracket by pivoting the platform with respect to the support bracket to interlock the platform and the support bracket and prevent the platform from inadvertently separating from the support bracket. If desired, the platform may be removed from the support bracket and moved to other trees having extra support brackets as required.

A distributor beam for depositing coating material on the surface of a sheet of glass includes a plenum for each gas to be mixed. The plenums are surrounded by a cooling fluid duct and heating elements are provided for temperature control. Theremocouples generate signals representing actual temperatures and the heaters are controlled to maintain an optimum temperature for the gases as they flow from the plenums through a mixing chamber to the surface of the glass sheet which is located below an outlet from the mixing chamber. Fastener means apply increased clamping pressure to the beam structure as the temperature increases to increase the rate of heat transfer to the cooling fluid.

Temperature controlled distributor beam for chemical vapor deposition

A distributor beam for depositing coating material on the surface of a sheet of glass includes a plenum divided by a septum for separating different coating gases. Outlets for the gases are connected to an inlet to a mixing chamber for separating and redirecting the flow of the gases to thoroughly mix them into a coating material. A finger baffle having two sets of alternating finger elements extends across the width of the mixing chamber. Each finger element has one end closer to the plenum outlet than an opposite end. The plenum is surrounded by a cooling fluid duct and heating elements are provided for temperature control. Thermocouples generate signals representing desired temperatures and the heaters are controlled to maintain an optimum temperature for the gases as they flow from the plenum to the surface of the glass sheet which is located below an outlet from the mixing chamber.
