Abstract: A mechanism suitable for a control lever such as a joy stick has two mutually perpendicular axes of rotation which provide movement in two planes. At least two close wound coil springs form a set and a set of springs is provided for each plane. The springs deflect when a force is applied on the control lever but return to a center position when the force is released. The mechanism avoids the use of shafts.

Abstract: An overflow level controller for a bathtub is provided with an adapter ring to facilitate connection with a conventional bathtub fixture base, and includes a housing with a removable covering. Rotation of the housing adjusts the overflow level of the bathtub.

Abstract: A tool for opening containers with a lid having an overlapping rim, engages the rim and levers the lid up. The tool avoids having to cut the lid and allows it to be removed without damage. The container has at least one peripheral rib extending around the wall below the lid and the tool comprises a lever arm having a handle at one end and a rim engaging lip at the other end, an anchor pivoted at a pivot position on the lever arm adjacent the rim engaging lip, the anchor having a top member adapted for engagement with the peripheral rib on the container wall, and a bottom stabilizing member adapted to rest against the container wall below the peripheral rib, such that when the tool is engaged with a container, the rim engaging lip positioned under the overlapping rim of the lid, and the top member of the anchor engaging the peripheral rim of the container wall, lever action of the tool raises the lid from the container.
