Abstract: A wheelchair frame member that includes a first metallic tube member, a second metallic tube member, and a tubular composite member. First and second end portions of the composite member extend into the first and second metallic tube members. The first and second end portions of the composite members are secured to inner surfaces of the first and second metallic tube members. The end portions of the tubular composite members may be connected to the inner surfaces of the metallic tube members in a variety of different ways. For example, the end portions may be forced radially outward into engagement with the inner surface of the tube members to secure the end portions to the inner surfaces of the tube members.

Abstract: A wheelchair having a seat frame and at least one side frame is provided. The seat frame includes, for example, a first distal portion having a first releasable attachment and a second distal portion having a second releasable attachment. The at least one side frame includes, for example, a first portion having a substantially horizontal section and second portion having a substantially vertical section. The first releasable attachment of the seat frame is attachable to the side frame substantially horizontal section at a plurality of positions and the second releasable attachment of the seat frame is attachable to the side frame substantially vertical section at a plurality of positions to adjust the position of seat frame.

Abstract: A dispenser for dispensing materials is provided including a container for holding the material to be dispensed, a plurality of frame portions for holding decorative items, locking apparatus for locking the frame portions to the container, and a dispensing means for dispensing materials from the container. The dispenser also includes a base for receiving the container and frame portions, a memory device for playing a sound when the dispenser is removed from the base, and a switch for activating the memory device when the container is removed from the base. The plurality of frames each contain an aperture and each aperture contains an inner edge operable to lock onto the container. The frames each contain clips to lock onto each other and hold the container. The dispenser includes a dispensing mechanism and the base includes an opening for receiving the dispensing mechanism.

Abstract: An apparatus for testing power transmission components of a locked gear train having two helical gears coupled on a first shaft meshed with two helical pinions coupled on a second shaft, with the two gears arranged to axially translate (while rotating) with respect to the two pinions when a linear force is applied to a thrust bearing at an end of the first shaft. The axial displacement of the two gears causes torsional displacements of the meshed gear and shaft elements, creating a dynamic torque within the locked train assembly. Under rotation, this dynamic torque subjects the components within the locked gear train to a much higher power level for testing.
