20100190420 | ABRASIVE DISC - To provide an abrasive disc which has a small size in the thickness direction and, therefore, can grind objects easily even if they are narrow portions or side walls of grooves and which has a strength enough for resisting the force applied during grinding. | 07-29-2010 |
20100304647 | Wheel polishing rotary stand - A device for polishing wheels of truck or cars without removing the valve or the tire of the wheel. The device comprises three parts: a rotative assembly fixed to a stand subject to an angular movement and housed upon a pendulum in extension. The rotative assembly includes a motor connected to a primary speed reducer 10:1 linked to a second speed reducer 60:1 fixed to a jaw turning at an average speed of 3 rpm, on which a wheel is positioned. The device is auto lubricating when a relative orientation of one reducer with respect to the other at 15° allows to maintain oil level in a critical reducer to prevent friction of mobile part inside the critical reducer. The pendulum possesses a pair of wheels to permit the displacement of the assembly on the ground while an actuator located on the pendulum causes the angular movement of the stand. | 12-02-2010 |
