Abstract: A resistance generating device includes a friction wheel adapted to frictionally engage a bicycle wheel of a training bicycle to be rotated therewith, a first magnetically attractive member, and a second magnetically attractive member which is rotated with the friction wheel, and which is disposed to be spaced apart from the first magnetically attractive member. The first and second magnetically attractive members are configured to be shiftable towards or away from each other in response to the higher or lower speed of the second magnetically attractive member so as to increase or decrease a magnetically induced resistance force generated therebetween to be imparted to the bicycle wheel. The actuating mechanism is disposed to effect the relative shifting movement in response to the higher speed to force the first and second magnetically attractive members towards each other, thereby increasing the resistance force.

Abstract: The present invention relates to an adjustable drive mechanism that converts a force supplied from an operator or other means along an adjustable curve path into rotary motion. More particularly, the present invention relates to an adjustable drive mechanism configured for an operator driven or motor driven exercise apparatus such as a stationary bicycle, recumbent stationary bicycle, cross trainer or other devices such as a bicycle. The present invention relates to the kinematic motion control of pedals which follow more complex curves that can be changed with the adjustable drive.

Abstract: The present invention relates to a standup exercise apparatus that simulates walking, jogging and climbing with arm exercise. More particularly, the present invention relates to an exercise machine having separately supported pedals for the feet and arm exercise coordinated with the motion of the feet. Elliptical cross trainers guide the feet along a generally elliptical shaped curve to simulate the motions of jogging and climbing. Existing elliptical cross trainers often use excessive pedal articulation which can overwork the ankle to achieve a longer stride. The present invention is an improved elliptical exercise machine capable of extended exercise with less pedal articulation that is more ankle friendly. One end of a foot support member has a pedal following elliptical motion while the other end is guided by an orbital link to drive an alternator and flywheel. The resulting pedal motion is foot friendly. Stride length can be adjusted.

Abstract: A floating aquatic stair stepper (1) having a frame (2) with support bars (6, 7), two extension legs (4) secured to the frame (2) and two foot placement steps (3) movably secured to each extension leg (4). The support bars (6, 7) permit a user to comfortably rest his or her hands, arms and shoulders, thereby permitting him or her to float. The foot placement steps (3) are each preferably slidably secured to extension legs (4). To use, a person raises and lowers each foot so as to simulate climbing stairs. The extension legs (4) may be fixedly secured to the frame (2) to provide for upward and downward movement only, or pivotally secured to the frame (2) to provide forward and backward movement of the legs as well. To further intensify the up and down movement of the present invention, resistance bands (5) may be used to secure the frame (2) to the foot placement steps (3).

Abstract: A process for the production of low sulfur, low olefin gasoline wherein a cracked naphtha, such as a full boiling range cracked naphtha, is first separated by fractional distillation into at least two fractions while simultaneously selectively hydrogenating the polyunsaturated compounds contained therein. The mono olefins in the light fraction are then subjected to etherification with alcohol to produce ethers or hydration with water to produce alcohols. The heavy fraction is subjected to sulfur removal by hydrodesulfurization or chemisorption. The two fractions are then combined to produce a low sulfur, low olefin gasoline.
