Abstract: Moisture and condensation barriers for protecting wood from damage in building structures (particularly but not necessarily in flooring systems) include a liquid rubberized coating material coated onto some of the wood or a barrier sheet having a petroleum-based tar layer.

Abstract: Moisture and condensation barriers for protecting wood from damage in building structures, particularly wood that is or may be exposed to moisture from internal or external sources, wherein such barriers comprise a non-vulcanized liquid rubberized coating material coated on to one or more portions of wood members of building structures.

Abstract: The glue dispenser comprises a collapsible tube having an externally threaded spout. A nozzle assembly comprises an internal nozzle threaded onto the spout and a external nozzle mounted on the internal nozzle. A nozzle valve registers with the opening of the external nozzle and is biased into closing engagement therewith by a deformable portion of the valve being urged against a cam surface. A piercing element is formed on the internal nozzle element, and when the nozzle is completely threaded down on the threads of the spout of the collapsible tube, the piercing element penetrates the sealing diaphragm of the spout so that the material in the collapsible tube can be squeezed through the spout and through the nozzle, with the nozzle valve controlling the flow of the material from the dispenser.

Abstract: A putty dispenser including a disposable cylindrical container is closed after being filled with putty and not opened again until after the container has been shipped and the putty has been dispensed from the container. A separator float is positioned inside the container and separates the putty from the air in the top of the container. A dispensing spout is centered in the bottom wall of the container and an air inlet spout is located off center in the topwall of the container. A non-drip putty dispensing valve is connectable to the dispensing spout, and air pressure is supplied to the container through the air inlet spout. A support frame is provided for supporting the container in an elevated position above a table top, or on a wall, etc., where the dispensing valve beneath the container is accessible.
