Abstract: A wall panel 100 has an elongate hollow body portion 102 having a storage cavity 103 provided therein for retaining water. The body portion 102 has a rectangular cross-section defined by an inner wall 104 and an outer wall 106 held in spaced apart relation by two side walls 108a and 108b. Each side wall 108 is adapted to be joined to the side wall 108 of an adjacent wall panel 100? so as to form a wall tank 110 for a building. Each wall panel 100 thus forms a structural component of the wall 110, which is sufficiently strong to support a roof structure 112 thereon. The side walls 108 are provided with an opening 120 therein, adapted to align with a matching opening 120? in the side wall 108? of an adjacent wall panel 100?, to permit the communication of water from the cavity 103 in one wall panel to the cavity 103? in the adjacent wall panel. The storage cavity 103 is bounded at the top by a lid 132 and at the bottom by a base tray 130.

Abstract: A wind turbine with at least one blade having a pitch axis that is offset laterally so that the blade does not intersect with an axis of rotation of the wind turbine, and a center of mass and an aerodynamic center are offset from the pitch axis in the direction parallel to the axis of rotation of the wind turbine. The blade is arranged so that the blade can pitch towards stall against the action of a resilient device and also so that the centrifugal loading on at least one of the blade and one or more components optionally attached to the blade, acts against the spring in a direction to shed power by pitching the blade towards stall and also so that the torque loading provided by a power conversion device acts to pitch the blade in the opposite direction, so as to reduce the amount of load shedding whenever the power is being extracted from the wind turbine.

The first member (9, 10) is provided with an annular array of permanent magnets (7, 8) coaxial with the common axis and configured to provide a substantially axial magnetic field passing through the second member. The second member (3) is provided with a first annular array of flat coils (1) coaxial with the common axis and arranged substantially side-by-side in a first layer and with a second annular array of flat coils (2) coaxial with the common axis and arranged substantially side-by-side in a second layer. The coils (2) of the second array are offset in a circumferential direction relative to the coils (1) of the first array.

Abstract: A butterfly type sponge mop includes a self-contained wringing mechanism comprising only two molded parts, an actuating lever and an enclosed yoke. A pair of hinged wings can be integrally molded onto one end of the actuating lever, and the lever can rotate back and forth within the enclosed yoke. Guides within the yoke can swing the wings closed when the lever is moved forward, squeezing a detachable sponge. The mechanical advantage of the actuating lever can increase as it is moved forward. Moving the lever back to its original position can cause the wings to swing back open, aided by the compression of the sponge.

Abstract: An improved dustpan includes an elongated receptacle with a lip at one edge of the perimeter of the receptacle and a handle or grip attached to the opposite edge. The handle extends away from the perimeter edge of the receptacle opening in a direction perpendicular to the lip and is unsupported at its far end. The elongated receptacle extends beneath the handle at least as far as the end of the handle, and can extend further. The elongated receptacle has a flat end wall that permits the dustpan to be stored upright without emptying or spilling its contents. In its upright storage position the dustpan lip is upward and the handle is downward. The end of the handle can stabilize the dustpan in its upright storage position. Several of the dustpans can be nested.

The locking device comprises a pair of separate arms, each arm having a principal length extending between first and second ends, the first end of each arm defining a stop adapted to confront one of the lockrods, and the second ends of the arms being adapted for secure interconnection in end-to-end abutting relation.

Abstract: A butterfly type sponge mop includes a self-contained wringing mechanism comprising only two molded parts, an actuating lever and an enclosed yoke. A pair of hinged wings can be integrally molded onto one end of the actuating lever, and the lever can rotate back and forth within the enclosed yoke. Guides within the yoke can swing the wings closed when the lever is moved forward, squeezing a detachable sponge. The mechanical advantage of the actuating lever can increase as it is moved forward. Moving the lever back to its original position can cause the wings to swing back open, aided by the compression of the sponge. The wings can be positively held in their open position by wing tabs that move in and out of corresponding pockets within the yoke as the actuating lever is moved forward and back. The actuating lever can be molded without die side actions, and the enclosed yoke can be molded with only a single die side action.

Abstract: A latch to secure a detachable sponge to a sponge mop head comprises a pair of opposed tabs separated by a void. The upper and lower portions of each pair are spaced to fit closely within corresponding apertures in the mop head, while the central portion ramps outward such that the dimension between the opposed tab ramps is larger than the aperture opening. Each tab is centrally locate on a beam, the beam extending a short distance beyond either end of the tab until it interconnects with a sponge backing plate. This short section of beam beyond each end of each tab twists or rotates torsionally when the tabs are squeezed together to secure or detach the sponge to the mop head. A latch is located near each end of the sponge.
