Abstract: An upper body attachment, which may be used with a piece of exercising, stretching, or massaging equipment that incorporates whole body vibration (WBV) technology, and provides a user with a way to apply WBV technology to the upper body. The attachment may include a pair of uprights and a crossbar to which a variety of types of handles may be slidably attached. The attachment may have a base that both supports the uprights and connects the uprights with the equipment incorporating the WBV technology. Accordingly, the attachment transfers vibrations from the vibrating equipment to the handles that a user grips. Several exemplary WBV upper body exercises that the attachment facilitates include push-ups, pull-ups, and dips.

Abstract: A motor support has a slidable carriage that includes a pair of elongated tubes slidably encompassing parallel elongated fixed cylindrical rails on a stationary base bed with bearing sleeves press fitted in the end portions of the glider tubes. The bearing sleeves support the guide tubes on the rails and transfer the motor load on the glider tubes to the rails with a reservoir of a viscous lubricant within the center portions of the glider tubes. A spring commands the strength of the movement of the slidable carriage and is sealed in a spring housing using one or more gusset plates.
Abstract: In a V-belt continuously variable transmission (CVT) of an ATV, a movable sheave half of a primary sheave is disposed on the outer side in the vehicle width direction with respect to a fixed sheave half, and a sheave drive mechanism for controlling the respective groove widths of the primary sheave and a secondary sheave through a driving force by an electric motor is located on the outer side in the vehicle width direction with respect to the movable sheave half of the primary sheave. A footboard of the ATV is located on the outer side of the V-belt CVT in the vehicle width direction and below a primary sheave shaft and a secondary sheave shaft. A portion of the electric motor is located above and in front of the primary sheave shaft as viewed in the sheave shaft direction. A straddle-type vehicle having the compact, yet durable V-belt continuously variable transmission achieves a speed change operation highly responsive to the vehicle running condition.
Abstract: A belt continuously variable transmission apparatus having a case which includes a power transmission case (which is part of a crankcase of an engine), a power transmission case cover, and an actuator cover assembled forwardly of the power transmission case cover (displaced forwardly on a vehicle body). The actuator cover is formed as a separate member from the power transmission case cover, and supports a motor for driving a movable part of a driving pulley. In addition, the actuator cover covers a gear system. The actuator cover is integrated with a cover of the water pump. The resulting configuration improves the assembling of the actuator cover of the belt continuously variable transmission apparatus.
Abstract: A hybrid power system, comprising a first power unit, a secondary shaft, a first transmission device, an auxiliary power unit, and a second transmission device. The first power unit has a primary shaft. The secondary shaft is driven by the primary shaft in a rotational movement. The first transmission device is placed between the primary shaft and the secondary shaft, having a transmission belt, transmitting torque from the primary shaft to the secondary shaft. The auxiliary power unit has an electric motor with a driving shaft, which is parallel to the primary shaft. The second transmission device is placed between the primary shaft and the driving shaft, transmitting torque from the electric motor to the primary shaft.
Abstract: A continuously variable belt drive system includes a driving pulley assembly, a driven pulley assembly and a V-shaped belt engaged to transfer rotary power therebetween. The driven pulley assembly includes a ratio adjustment mechanism that adjusts the position of a rear sheave relative to a forward sheave. The adjustment mechanism includes a motor and a worm gear mechanism that rotates an actuation screw. Rotation of the actuation screw is reacted by a split nut that translates the screw rotates along the axis of the driven pulley assembly. In one feature, the driven pulley assembly includes a fail-safe mechanism that operates when power is supplied to the motor to hold the split nut together. In another aspect of the invention, the driving pulley assembly includes a belt tensioning mechanism that maintains proper belt tension at all speeds and drive ratios.
Abstract: A gear reducer having a hollow shaft is telescopically mounted on the upper end of a vertical conveyor drive shaft. The gear reducer is removed for repair by raising the gear reducer housing to separate the hollow shaft from the drive shaft while the drive shaft remains on the drive frame.
Abstract: A rotary woodworking machine includes a longitudinally extending transmitting shaft having two ends respectively coupled to two rotary woodworking members. A speed ratio varying device is disposed to couple the transmitting shaft to an output shaft of a motor, and includes two pitch-variable first and second pulleys mounted on the transmitting shaft and the output shaft, a belt trained on the pulleys, and a control unit operable to move a movable disc of the first pulley toward or away from a fixed disc of the first pulley so as to vary the radial distances between the belt and each of the shafts, thereby varying the speed ratio of the transmitting shaft to the output shaft.
Abstract: The invention effects an increase in the range of continuously variable tool speed and torque control for machine tools beyond that conventionally available for operation from single phase alternating current. Interactive operator control of mechanical speed regulation is additively coupled to electrical control of direct current motor drive to reduce or eliminate machine down time needed for performing a series of varied machine operations.
Abstract: A rubber having fiber reinforcement embedded thereon. The reinforcement comprises a cylindrically braided cords of more than four and even numbered twisted yarns. Yarns are right twist oriented and left twist oriented and they are twisted in the reverse direction in an, S-twist and a Z-twist.
Abstract: A method and apparatus for controlling a motor is disclosed in this application. A means for loading the motor is provided and the loading means is operatively connected to the motor. A variable drive means is operatively connected between the motor and the drive means. The variable drive means is capable of changing the loading on the motor. A sensing means is provided for actuating the variable drive means so the loading on the motor can be varied to keep the motor operating at substantially the maximum capacity of the motor.
Abstract: A variable speed drive wherein a first embodiment is comprised of a pivotally mounted prime mover (10) coupled to a rotary fluid output device (58), such as a fan or pump, through a variable and fixed pulley drive arrangement (50 and 52) wherein the pivotal position of the prime mover (10) and accordingly the pitch diameter of variable pulley means (50) is controlled in accordance with fluid motor means (26, 28) coupled to the prime mover (10) and which is actuated in response to a fluid feedback control signal derived from a sensed output of the rotary fluid output device (58). The pivotal motion of the prime mover (10) imparts an arcuate motion to the variable pulley means (50) which effects a speed variation of the rotary fluid output device (58) in accordance with the variation of the pitch diameter ratio of opposing variable and fixed pulley means (50 and 52).

Abstract: The fan motor of a variable speed drive for a fan is positioned in response to thermostatic demand and a feedback signal responsive to the position of the variable speed drive. Changing thermostatic demand causes movement of the fan motor until an equilibrium position is reached again.
Abstract: The belt of a variable speed fan drive is replaced without the use of tools. The high speed limit switch is bypassed and an override connection switch striker is provided which permits further movement of the motor base beyond the high speed limit when the high speed limit switch is bypassed.
