摘要： An improved belt clutch engages to couple one shaft to at least one other shaft and disengaged to decouple the shafts. Known belt clutches fail to smoothly and completely disengage the belt from traction pulleys on the shafts and drag results. The improved belt clutch includes rollers outlining the engaged belt and constrain the disengaged belt to smoothly and completely disengage the belt from the traction pulleys. The new improved belt clutch provides, among other things, higher efficiency when driven in either direction and smoother operation when engaged or disengaged at high speed than prior art belt clutches.

摘要： A braking system preferably for an in-line skate includes a brake pad mounted to a forward end of a skate frame and an elevated front wheel attached to the skate frame by two pivot arms. The pivot arms are biased forward which is in a clockwise direction with respect to their pivot point. When skating normally, the pivot arms bias the wheel against the brake pad, but the wheel is elevated from the skating surface and thus the brake is not engaged. When skating in a rearward direction, or desiring a push start, the skater rotates the toe portion of the skate downward and raises the heel. The front wheel will engage the skating surface and the reaction force on the wheel due to friction between it and the skating surface which will urge the wheel forward and increase the contact pressure between it and the brake pad. When skating forward, if the skater rotates his or her foot so that the front wheel engages the skating surface, the frictional force between the surface and the wheel causes a rearward force on the wheel away from the brake pad, thus ensuring that the skater will not trip due to sudden braking of the front wheel.

摘要： A modified football game requires that players wear in-line skates and the field has a flat surface area having a substantially rectangular shape with two straight long sides and two second convexly curved short sides, a partial circular concavely curved second surface area bounding the first area and having a lower edge and an upper edge, the lower edge being contiguous with the edge of the first flat surface area, and the upper edge being remote from the flat surface area, and an upper flat lip surface area extending around the curved second surface area contiguous with its upper edge, and lines defining end zones proximate each of the second curved short sides of the flat surface area, each end zone having a flat surface area portion and a curved surface area portion of the curved second surface. The players skate on the flat area, the curved area and the lip. The players score a first amount of points for skating the ball into the end zone or catching the ball in the end zone in the flat surface area, and a second amount of points for catching the ball in the end zone on the curved area. There may also be a third highest amount of points for catching the ball in the end zone on an upper portion of the curved area. There are no goal posts, and thus there are no field goals or kicked point after attempts. The sides of the field corresponding to sidelines where the curved second surface area such as a quarter pipe or portion of a quarter pipe used in in-line skating is located is preferably a cut-off portion of quarter pipe, while the curved area in the end zone is preferably a full quarter pipe or a full quarter pipe with an extension upward, such that the height of the lip in the end zone is higher than that on the sidelines.

摘要： A standing valve which may be retrievably mounted in a well production tubing and will allow the maximum possible fluid flow and also allow the valve to be easily drained and retrieved through the well production tubing. The seal between the standing valve and the bottom hole assembly is located at or below the level of the seat and fluid from the top of the valve into the well is drained through the seat.

摘要： An internal combustion engines keeps the pistons at or near the End Of Stroke (EOS) for the whole time or most of the time that fuel is burning or while fuel is injected into the engine. A scotch yoke embodiment includes a curved slot to extend the piston's time at (EOS). A second embodiment includes a cam on the crankshaft and a follower. The shape of the cam extends the piston's time at (EOS).

摘要： A lipless tubular oil seal assembly uses a tubular type of seal. The new seals create only enough pressure against the casing to provide an adequate seal under most conditions and the small amount of oil that would leak by on the roughest well casing surfaces acts as a lubricant. The new seal has no lip so it cannot turn under and get stuck in the well casing like a cup seal, even under the roughest conditions.

摘要： An electric powered vehicle includes a first drive unit and a second drive unit. The first drive unit and the second drive unit are coupled to one of the drive wheels. At its maximum power within the system, the second drive unit drives the vehicle at a higher speed than the first drive unit. A clutch automatically disengages the first drive unit from the drive wheel while the second drive unit is operating. The clutch may include a uni-directional device. An electronic control unit automatically adjusts the voltage supplied to the second drive unit to maintain the efficiency of the second electric drive unit within a predetermined efficiency range.

摘要： A protective uniform for a high-risk or high-impact activity or sport has a rear rigid shell, an artificial spine which may articulate at two sections attached to the shell, and a damper mechanism between the shell and artificial spine. In addition, the artificial spine may be attached to conventional or modified back and hip pads and/or a harness such as worn by rappellers or skydivers. The shell preferably extends from the wearer's head to the tailbone and across the back. The top portion of the shell together with side shields and a face shield form a protective enclosure for the head, inside of which a conventional helmet may be worn. The side shields preferably are movably connected to the rigid shell and are also connected to conventional or modified shoulder pads. The artificial spine is preferably formed in three sections, each section being connected to the other by a limited range universal joint to provide a range of motion comparable to the human neck and the human back. Alternatively, the upper section may be fixed to the middle section and the lower section may have a swivel or universal connection to the middle section.
