International Classification:

B21B 1/10

US Classification:

72101, 72 84, 72121, 72125

Abstract:

A method and apparatus for spin forming a portion of a workpiece where the formed portion has a formed axis that is non-coaxial with the non-processed axis of the workpiece includes at least two rollers rotatable about a spin axis. Each one of the rollers is axially and radially offset from the others. An axial drive mechanism reciprocates the rollers or workpiece to causes the first roller and then the second roller to sequentially engage the workpiece. A pivoting mechanism rotates the rollers or workpiece about a pivot point from a first angular position to a second angular position during a forming operation to create a formed portion that is oblique to the non-processed portion or is substantially curved. A higher reduction ratio is achieved which enables improved efficiency. The present invention reduces floor space requirements as the forming operation may be completed on a single machine.

International Classification:

B01D 50/00

US Classification:

422179, 422180

Abstract:

An end cone assembly for an exhaust emission control device includes an inner cone spacedly disposed within an outer cone. The outer cone comprises a small outer cone end a large outer cone end and an outer wall that diverges from the small outer cone end to the large outer cone end. The inner cone comprises a small inner cone end and a large inner cone end with an inner wall having a first diameter proximal the first inner cone end, wherein the inner wall diverges to a second diameter, wherein the second diameter is disposed proximal a recessed portion having a third diameter at the second inner cone end, and wherein the first diameter is smaller than the third diameter and the third diameter is smaller than the second diameter. The outer wall is disposed in a spaced relation to at least a portion of the inner wall, and, with the exception of the recessed portion, the space between the inner and outer walls is free of insulating material. Disposed within the recessed portion of the inner cone is an insulating member.

US Classification:

422/179000, 422/168000

Abstract:

An endcone assembly for use with a catalytic converter comprises a conical shaped sidewall extending outward to a shoulder having a first diameter. A mat protection element having a second diameter extends from the shoulder. The mat protection element has a second diameter that is equivalent to or less than the diameter of the conical shaped sidewall. The mat protection element includes a sidewall having at least two ribs or dimples that protrude outwardly from the sidewall to impart additional retention, positioning and alignment properties to the endcone assembly when being placed within a catalytic converter assembly. The edge of the sidewall either contacts a leading edge of the mat support material, or penetrates the leading edge of the mat support material, when the endcone assembly is disposed within the catalytic converter.

International Classification:

A61F 5/01

US Classification:

602 16, 602 26

Abstract:

The exoskeletal dynamic load bearing shock absorbing knee brace makes use of the energy absorbing characteristics of specifically designed industrial shock absorbers which are held precisely in place by an articulated dynamic exoskeletal structure that is to be secured to the lower limbs of the individual with the injured knee. The exoskeletal structure is designed using the principles of the overcenter linkage to translate and transfer to the shock absorbers a representative fraction of the normal and extra normal ambulatory movements of the lower limbs of the user which makes possible for these shock absorbers to absorb a corresponding amount of energy and provide an alternate load bearing structure parallel to the knees thus introducing a desirable degree of protection for the injured knee.

Abstract:

The exoskeletal dynamic load bearing shock absorbing knee brace makes use of the energy absorbing characteristics of specifically designed industrial shock absorbers which are held precisely in place by an articulated dynamic exoskeletal structure that is designed not to restrict any freedom of movement when attached to the legs of the individual with the injured knee using the device. The exoskeletal structure is designed using the principles of the overcenter linkage to translate and transfer precisely and accurately in a repeatable manner, to the shock absorbers a representative fraction of the normal and extra normal ambulatory movements of the lower limbs of the user which makes possible for these shock absorbers to absorb a corresponding amount of energy, and provide an alternate load bearing structure parallel to the knees thus introducing a desirable degree of protection for the injured knee.

International Classification:

A63B 2508

US Classification:

272114

Abstract:

A hopping vehicle is provided comprising an elongated frame having a lower end adapted to engage a ground supporting surface and having handle bars secured to its upper end. A pair of elongated foot levers are pivotally secured at one end to a horizontal carriage assembly longitudinally slidably mounted to the frame near its lower end. A stirrup for supporting an operator's foot is secured to the opposite end of each foot lever. The first end of each foot lever is selectively connected to a gear segment which when connected, rotates in unison with the foot lever. Each gear segment in turn meshes with a stationary gear rack secured to the frame. An elongated helical spring is disposed between the upper end of the gear rack and a spring retainer longitudinally slidably mounted on and near the top of the frame. Connecting bars connect the carriage assembly to the spring retainer so that pivotal action of the foot levers from their upper and to their lower position forces the retainer longitudinally downwardly and toward the gear rack thus compressing the helical spring between the retainer and the gear rack. A release mechanism, which can be either automatically controlled upon engagement of the hopping vehicle with the ground or manually controlled by the operator, disengages the gear segments from the foot levers which permits the spring to expand and provide the propulsion power for the hopping vehicle.
