Abstract:
A floorboard assembly comprises first and second solid wood floor boards (10) and (12). The first floor board (10) has a tongue (14) extending longitudinally along a first side thereof. The second floor board (12) having a groove (16) extending longitudinally along a second side thereof. The groove (16) has a width defined between a top lip (22) and a bottom lip (24). The tongue (14) is insertable in a tight fit manner in the groove (16) to prevent translational separation of the boards (10, 12) in a common plane thereof. A clearance (26, 26′, 28, 32, 32′, 32″, 36 and 38) is provided between the tongue (14) and the groove (16) at one of a tip portion of the tongue (14) and an outermost portion of the top and bottom lips (22, 24) of the groove (16). The clearance (26, 26′, 28, 32, 32′, 32″, 36 and 38) is configured to allow angular withdrawal of the tongue (14) from the groove (16) by manually pivoting the first and second floor boards (10, 12) towards one another in one of an upward and a downward direction.
Abstract:
The undersurface (22) of the floorboards (10) is used as a main reference for taking measurements in a tongue and groove floorboard quality control process. The process comprises measuring at least one distance (X, Y) between the undersurface (22) and a downwardly facing surface of at least one of a tongue and a groove profile of selected ones of the floorboards (10). Measurements can be taken from the undersurface (22) of the selected boards (10) on both sides thereof to vertically adjust the relative position of groove cutter head (18) and the tongue cutter head (16) of the moulding machine (M) used to manufacture the boards (10). A depth gage (G) can be used to take the measurements.

Abstract:
A solar powered system for operating the gates, chutes, and lid of a fracking silo. The solar powered system comprises at least one solar panel adapted to be attached to an outer surface of the fracking silo; at least one solar power battery adapted to be housed within a base portion of the fracking silo. Each the at least one solar power battery being electrically connected to the at least one solar panel and adapted to store the solar power absorbed by the at least one solar panel, and a control panel adapted to be placed within the fracking silo and electrically connected to the at least one solar power battery, and adapted to control and transfer the solar power stored by the at least one solar power battery, wherein the control panel includes a solar charger control device adapted to regulate the at least one solar power battery and transfer a desired amount of solar power therefrom to actuators within the fracking silo to thereby open and close the gates and lid, and move the chutes of the fracking silo.
