Abstract: An exercise apparatus includes a frame that is adapted for placement on the floor, a pivot axis supported by the frame, a pedal bar which has first and second ends, a pedal that is secured to the pedal bar, an ellipse generator, and a track. The ellipse generator is secured to both the pivot axis and to the first end of the pedal bar such that the first end of said pedal bar moves in an elliptical path around the pivot axis. The track is secured to the frame and engages the second end of said pedal bar such that the second end moves in a linear reciprocating path as the first end of the pedal bar moves in the elliptical path around said pivot axis. Consequently, the pedal also moves in a generally elliptical path. As the pedal moves in its elliptical path, the angular orientation of the pedal, relative to a fixed, horizontal plane, such as the floor, varies in a manner that simulates a natural heel to toe flexure. The apparatus can also include a resistance member, a data input member, and a control member.

Abstract: An exercise apparatus having a collapsible frame that simulates walking, running and climbing depending upon where the foot is positioned along the elongate pedal. The user is able to maintain a standing posture while elongate pedals supporting each foot move through an exercise cycle having a different mode for each foot position that includes translating and non-parallel angular motion generated by a linkage mechanism.

The user is able to maintain a standing posture while elongate pedals supporting each foot move through an exercise cycle having a different mode for each foot position that includes translating and non-parallel angular motion generated by a linkage mechanism. Arm exercise is provided by rocker extensions which are phased with the crank to use arm force for moving the crank through dead center positions.

Abstract: An exercise apparatus that simulates uphill cycling where the user is able to maintain a preferred standing posture while programmed pedal platforms supporting each foot move through an exercise cycle that includes translating and non-parallel angular motion generated by a linkage mechanism. Simple harmonic load resistance acting upon the linkage mechanism is provided by drag pulleys or viscous damping cylinders for high intensity cycling exercise without dead center rotary crank problems.

Abstract: Method to produce a non-woven needled fabric in which the needled fabric includes 10-35% of low melt fusible fibers to aid in holding the non-woven fabric together when passed through and over to melt the fusible fibers and then allow to cool and bind the fabric together.

Abstract: Method and apparatus to soften the backing and consequently the material attached thereto of a nonwoven fabric by passing the back over and around a series of rollers arranged in a staggered diamond shape to break up the bond between individual fibers and clumps of fibers but maintain the bond at cross-over points of the fibers.

Abstract: A laminated fabric having a face layer of plush fabric, an intermediate layer of foam material and a bottom layer of scrim fabric having an elasticity of at least 100% in the warp and fill or course direction of the fabric.

Abstract: Method to produce a spun-like textured yarn comprised of one yarn which is substantially fully oriented and the other yarn is partially oriented. The method involves plying the yarns in the draw zone before being pre-textured. The ply point of the plied yarns is located above the entrance to the heater in the draw zone.

Abstract: A boucle yarn is produced by entangling a drawn core yarn and an air textured, drawn effect yarn. The air textured, drawn effect yarn provides a plurality of randomly spaced curls or loops around the core yarn to produce the boucle yarn appearance. A number of the random curls or loops are embedded in the core yarn during the entangling process.

Abstract: Method to produce spun-like yarn and product produced thereby by combining a core yarn and an effect yarn in an air jet. The removal speed of the combined yarn from the air jet is intermediate of the speeds of the draw rolls to produce a composite yarn having crunodal loops in one of the combined yarns.

Abstract: Method to produce an entangled yarn product by air entangling a drawn core yarn and a drawn effect yarn. The effect yarn draw ratio is higher than the core yarn draw ratio which results in a composite yarn in which the birefringence of the core yarn is greater than that of the effect yarn.

Abstract: Apparatus and method to provide a novel false twisted slub yarn by combining a core yarn and an effect yarn in a fluid tangling zone. The linear velocity of the effect yarn is raised to allow slubs to be produced in the combined yarn in an air jet apparatus.
