Abstract: A safety mat securement assembly for providing an open and a closed position for a climbing wall assembly using a safety mat. The safety mat securement assembly may utilize a plurality of security hand hold members each having latching means and a safety mat having a plurality of bottom securement members, top and side loop members. The security hand hold members may be used as hand holds on the climbing wall assembly and may have a locking structure. The hand holds may also have embedded securement structures to provide for the attachment of climbing related devices. The bottom securement members function to hold the safety mat to the bottom of a climbing wall assembly during both open and closed positions of the safety mat. The mat securement assembly is opened or unlocked by loosening the latching means, removing security mat top loop members from the hand hold, and placing the mats on the floor along the base of the climbing wall.

Abstract: A wind turbine generator assembly comprising a support tower and a turbine assembly mounted in a downwind position with respect to the support tower. The turbine assembly comprises a cowling assembly and a spoked wheel having a plurality of relatively short blades mounted radially outward with respect to and downwind the cowling assembly. Each blade has an airfoil cross-sectional configuration of a predetermined structure to provide lift. The bladed wheel is coupled to a generator to produce electricity. The support tower has an upper tower portion having a biased hinge assembly with respect to the lower tower position to permit the turbine to pivot in high wind conditions. The support tower further has a rotating mechanism above the lower tower portion and below the biased hinge assembly to allow the turbine to rotate with respect to wind direction and a pivot assembly is provided to permit the turbine assembly to be brought to ground level for erecting and maintenance purposes.

Abstract: A climbing wall assembly for educational and recreational purposes. The climbing wall assembly has a plurality of adjacently positioned wall panels, each having an exterior paint/aggregate textured surface adapted for educational purposes. A plurality of wall apertures are provided for mounting hand hold structures so that a plurality of climbing paths may be provided. Markable paint/aggregate climbing wall surfaces are also provided. Removable magnetic and metallic educational elements may also be utilized by the climbers. A paint/aggregate layer having metallic or magnetic particles mixed therein may be utilized to provide the magnetic climbing wall surface and to provide magnetic qualities to climbing wall components.

Abstract: A rupture disc assembly for pneumatic plugs constructed and arranged to cooperate with an aperture in an end casting or other plug component to expel excess air from the plug interior when a predetermined internal plug pressure is reached. The rupture disc holder assembly may have a two part body structure and be mounted to the inside or outside of the pneumatic plug. The rupture disc assembly utilizes a rupturable member in a flanged holder structure positioned in communication with the pneumatic plug.

Abstract: A patient laser goggle having a pair of eye cup assemblies adjustably joined to a formed bridge wire having collinear ends. Each eye cup has a clamping mechanism to which each bridge wire end is held and a strap hook to receive the looped ends of an adjustable band. The collinear bridge wire ends are horizontally and tiltably held within the clamping mechanisms so that the patient laser goggle can be easily custom fit to the eyes of a patient. Once adjusted, the clamping mechanism allows rotation of the bridge wire with respect to the eye cup so that a medical practitioner can have easy and unobstructed access to areas of the patient's face.
