A wind turbine rotor blade extension portion having a plurality of segments, located adjacent one another in a span-wise sense. An interface between adjacent segments is configured to minimise disruption to fluid passing thereover and to inhibit transmission of longitudinal loads between segments. Each segment has a first surface and a second surface. The first surface is spaced from the second surface at a proximal region of the extension portion and the first surface is connected to the second surface at a distal region of the extension portion to thereby generate a fair surface for a rotor blade to which the extension portion is connected, in use.

A massage chair includes a base frame; a cradle in which a person sits, the cradle being rotatably mounted to the base frame on a cradle bearing structure and pivoting at a cradle axis, the cradle including a vibration generation mechanism mounted within the cradle for producing and delivering vibration into the body of a person seated in the cradle; and a having cradle pivot mechanism connected to the cradle for pivoting the cradle relative to the base frame to a sitting position in which the center of gravity of a person seated in the cradle is substantially over the cradle axis to evenly distribute the weight of a person seated in the cradle over the cradle, and for pivoting the cradle to at least one reclining position.

A top-fill hummingbird feeder has a generally upstanding reservoir bottle or liquid container with a large opening at its top end that is closed and sealed by a removable top or cap. The bottom of the bottle or container has a lower bottom opening which can be screw-threaded into a central collar of a feeding basin that has a plurality of feeding ports. A tubular insert is received within the central collar and is configured to be vertically movable between a first position in which fluid is allowed to flow from the liquid container to the basin, and a second position in which fluid flow from the container to the basin is prevented. Movement of the insert between the two positions is effected by pushing the liquid container toward the basin (the closed position) and by pulling the liquid container away from the basin (the open position). Each movement of the insert has an associated “snap” or gives positive physical feedback which the user can feel that assures the user that the desired fluid flow or fluid sealed position has been achieved.

A cookware lid assembly having a whistling handle and a removable flexible sealing band that extends around a flange on the lid. The sealing band secures the lid to the cookware to prevent the lid from being dislodged from the cookware as pressure inside the cookware increases or as water in the cookware comes to a boil. The handle has a hole in it that generates as whistling noise when the pressure in the cookware increases. A movable slide in the handle allows the hole in the lid to be closed or remain fully or partly open. The slide also allows the volume and pitch of the whistle to be adjusted.

A modular apparatus for supporting and guiding a tool such as an ultra-high pressure water jet along a work surface, including a contour following assembly attached to a motorized lift vehicle. The contour following assembly includes a gimbals assembly with an instrument or tool carriage assembly, a positioning assembly that urges the gimbals assembly and the instrument carriage against the surface, and, optionally, a hydraulic, mechanical, or pneumatic pressure system that applies pressure to the positioning assembly. A scissors lift, hydraulic lift, telescoping arm, or other suitable device raises and lowers the apparatus. In operation, the gimbals assembly and the positioning assembly cooperate to maintain the instrument carriage in a user-selected position with respect to a work surface such as a ship hull, aircraft fuselage, storage tank, or the like. Depending on the type of tool selected, the apparatus may be used for cleaning or stripping surface coatings, buffing, painting, washing, and so forth. The apparatus is mobile, compact, cost-effective, and can be operated by a single operator.

The metering module is configured and sized to discharge a predetermined quantity of the food when the impeller rotates over a predetermined rotation angle. The impeller rotation detector detects that the impeller has rotated over the predetermined rotation angle after the power drive unit has been energized to detect dispensing of the predetermined quantity of the food.

A system for rapid collection of large volumes of dissolved gases from groundwater pumps the water from a large-diameter passage through a small-diameter restrictor passage, and then into a flow-through collection chamber. The small-diameter passage causes a drop in the hydrostatic pressure of the groundwater traveling therein, causing spontaneous ebullition of gas bubbles, which are then collected in the collection chamber. A treatment station within the passages selectively alters the concentration of dissolved gases within the groundwater. Testing reveals that the gases are collected in proportion to their presence in the groundwater, and thus the system allows accurate quantification of concentrations of dissolved gas in groundwater. The system may beneficially be made easily portable, thereby allowing its use in the field, as well as in laboratory settings.

A flooring system includes a plurality of individual flooring pieces, such as floor panels, each having a wear surface, an opposing mounting surface and a retention groove disposed within the mounting surface. A floor panel connector used to interconnect at least two of the floor panels has a base, at least one mast extending from an upper surface of the base and a pair of flexible arms. Each flexible arm extends transversely from opposing sides of the at least one mast and has an extending end. Contacting portions extending from a lower surface of the base are configured to engage the support surface and create a spacing between each flexible arm and the support surface to permit each flexible arm to elastically deflect toward the support surface when pressure is exerted on a floor panel. This deflection enables the extending end of each flexible arm to engage the retention groove of a corresponding floor panel.
