Abstract:
A heating system in the form of a multi-layer, yet relatively thin and flexible panel. The panel contains a number of layers including first, second and third electrically insulating layers. A first electrically conductive resistive layer (heater layer) is sandwiched between the first and second insulating layers. A second electrically conductive resistive layer (resistive neutral plane layer) is sandwiched between the second and third insulating layers. The heater layer has a neutral electrical connection and a live electrical connection. The neutral and live electrical connections are electrically connected to each other at the panel only by electrically resistive material of the heater layer extending between the neutral and live electrical connections. The resistive neutral plane layer has a neutral electrical connection electrically connected with the neutral connection of the heater layer. The resistive neutral plane layer is electrically isolated from the live connection of the heater layer by the second insulating layer.
Abstract:
A heating system which may include a bonding membrane having a water permeable lamina, an electrically conductive ink-based radiant heater, and a first adhesive adapted to adhere to both the conductive ink-based radiant heater and the bonding membrane. The heating system may be incorporated in a floor including a substrate, the heating system and a decorative floor surface. The heating system may also be in the form of a multilayer panel having a bonding membrane, an electrically conductive ink-based heater including a plurality of electrically resistive strips printed on a first polymer sheet connected by electrically conductive buses, and electrical conductors extending from the buses to at least an edge of the panel.

Abstract:
A process for producing fiber-reinforced structural cementitious panels made of at least one layer of fiber reinforced cementitious slurry, the process for each such layer of slurry including providing a moving web; depositing a first layer of individual, loose fibers upon the web; depositing a layer of settable slurry upon the deposited first layer of individual, loose fibers; depositing a second layer of individual, loose fibers upon the deposited layer of settable slurry; and actively embedding both layers of individual, loose fibers into the layer of slurry to distribute the fibers throughout the slurry.
