Abstract: An engine exhaust dispersing device includes a tubular member having a first portion formed as a generally cylindrical wall and adapted to be mounted in fluid communication with an exhaust outlet and a second portion formed as a longitudinally-sectioned cylindrical wall defining a longitudinally extending opening, and, a wedge surface formed on said second portion and protruding into the longitudinally extending opening, the wedge surface having an apex adjacent or in the first portion and a base at an end of the second portion, the base having a width substantially equal to a width of the second portion.

Abstract: This invention relates to a spinal facet cap for treating scoliosis, the facet cap comprising a shim portion for inserting into a facet joint of a spine, and an alignment portion for maintaining alignment of the shim portion within the facet joint. The invention also provides a method for treating scoliosis, comprising implanting at least one spinal facet cap into at least one facet joint of a subject in need thereof.

Abstract: An artificial limb consisting of a tubular member having inner and outer walls and formed by at least three interconnected side-by-side air inflatable compartments fabricated from an air impervious flexible material. The stump of a patient's limb may be inserted into one end of the tubular member, which preferably tapers therefrom towards the other end, and is gripped by the inner walls thereof when the compartments are inflated. Below the stump the inner walls interengage with one another as the compartments inflate and in order to provide a sufficiently rigid pylon to fully support the patient's weight a plurality of rigid longitudinal stiffening members are disposed around, and cooperate with, the outer walls of the tubular member. Preferably the stiffening members are hingedly interconnected along longitudinal marginal side edges and fabricated from a single sheet of rigid transparent thermoplastic material such as polyvinylchloride.

Abstract: A device for measuring rib hump angle in the diagnosis of scoliosis, which comprises a frame, a plurality of stiff, laterally spaced parallel finger-like members arranged in pairs along one side of the frame with the two members of each pair equally spaced on opposite sides of the centerline of the edge, and frictionally slidable on the frame parallel to the centerline of the edge, so that when the frame edge is transverse and perpendicular to the longitudinal axis of the spine each finger-like member can be pushed into contact with the back. Means are also provided on the frame to measure the angle subtended between a first line perpendicular to the movement of the fingers and a second line intersecting the first line and passing through a selected point on the highest finger on the "high" side of the spine and the corresponding point on the other finger of the pair on the other or "low" side of the spine, so that rib hump angle can be measured directly.

Abstract: An artificial limb consisting of a tube like member having an inner wall and an outer wall, each of flexible air impervious material sealingly joined together at respectively opposite ends of the tube and along at least three lines extending longitudinally of the tube. The longitudinal seams are spaced apart from one another providing a plurality of side by side air inflatable compartments. At least one compartment is provided with an air inlet passage means for inflating the artificial limb and the compartments are in communication with one another so that there is equalization of pressure in all of the chambers. The inner and outer walls are preferably a transparent plastics material and the tube tapers in a direction from one end to the other. A protective cap may be detachably mounted on the lower end of the limb and such cap may be provided with fins projecting into the sleeve to stiffen the same if so desired.
