Abstract: A tire and/or wheel testing machine and method for operating the same allows testing without removal of a drive motor that is only used during some of the tests. One aspect is a testing machine wherein the drive motor is supported by a support member so that the motor axis intersects with a spindle plane having the spindle axis. Another aspect includes a coupling assembly allowing selective decoupling of the motor shaft with the spindle hub.

Abstract: An exercise resistance device for use in an exercise apparatus includes a rotatable shaft and an impeller rotatable within a fluid filled sealed chamber. A rotating member is joined for rotation with the rotatable shaft. The rotating member is external to the sealed chamber and is magnetically coupled to the impeller.

Abstract: An open roof construction for a vehicle having an opening in its roof, the front part of which opening can be closed by a first panel which is pivotable about a substantially horizontal axis at the front edge thereof, while the remaining part of the roof opening can be closed by means of at least one slidable second panel, comprises a wind deflecting arrangement that functions as a wind deflector. Said wind deflection arrangement can be moved rearwards and upwards, using suitable driving means, from a position of rest under the first panel to an operative position substantially above and behind the first panel. The wind deflection apparatus may be pivotable about a horizontal pivot that extends substantially transversely to the vehicle.

Abstract: A crank-connecting rod mechanism for an internal combustion engine or the like comprising a shaft rotating around its axis, a first crank fixed to the shaft and a crank pin fixed to the first crank. A crank pin extends parallel to but at a first radial distance from the shaft. A second crank rotatably mounted onto the first crank pin is fixed to a second crank pin having an axis at a second radial distance from the axis of the first crank pin. A connecting rod is rotatably mounted on the second crank pin. Rotary means are provided to force the second crank to rotate relative to the first crank upon a rotation of the shaft.
