A platen can be driven by the output member. A sensor assembly can be configured to sense a condition in which a pressing force in excess of a predetermined force is applied to the sander in a direction normal to the platen and generate a sensor signal in response thereto. A controller can receive the sensor signal from the sensor assembly and control operation of the indicator in response thereto. The sensor assembly can include a force sensing resistor. The force sensing resistor can be disposed adjacent to a gripping portion of the power sanding tool. The indicator can include at least one light source. The controller can illuminate the light source according to a schedule. | 12-18-2008 |
| 20080311833 | SANDER - A sander can include a housing, an indicator coupled to the housing, and a motor assembly in the housing. The motor assembly can include an output member. A platen can be driven by the output member. A DC generator can be driven by the output member. The DC generator can generate an output signal with a voltage that is related to a rotational speed of the motor. A controller can operate the visual indicator based on the voltage of the output signal. According to additional features, the DC generator can provide electrical power to operate the indicator. An electric power input can be electrically coupled to the motor. The visual indicator can be electrically isolated from the electric power input. | 12-18-2008 |
| 20090124183 | Pneumatic adjustable sanding device - An attachment for an oscillatory sanding or abrading device has a pair of flexible support members for supporting the sanding or abrading material. The initial radius of curvature of the flexible support member may be adjusted by a pneumatic adjustment mechanism. An opposing pair of generally cylindrical bladders are disposed proximate end portions of the flexible support member, the bladders being releasably attached between the underside of the abrading device and the support member. Adjustment of the initial radius of curvature of the flexible support is accomplished by selectively inflating one or both of the bladders. The radius of curvature of the flexible support member during the sanding process is then a function of the applied pressure or inflation of the bladders. The device allows for virtually infinitely varying adjustments of the curvature of the flexible sheet and the attached abrading sheet. | 05-14-2009 |

| 20090221220 | DEVICE FOR POLISHING OPTICAL FIBERS MOUNTED IN A CONNECTOR - The invention relates to a device for polishing the end of at least one optical fiber mounted in a connector, the device comprising a moving part supporting at least one connector and another moving part carrying a polishing film, the movement of these two parts being synchronized. According to the invention, these two parts are in direct contact via a movement transmission element, movement of one of them giving rise to movement of the other. | 09-03-2009 |
| 20100009607 | CONVERSION ASSEMBLAGE ADAPTABLE FOR USE IN COMBINATION WITH A SURFACE MODIFYING APPARATUS AND METHOD THEREOF - The disclosure is directed to a conversion assemblage adapted for use in converting a surface modifying mechanism, such as a pole sander, having an attaching member. The surface modifying assemblage and method facilitate converting the pole sander with anyone of several different surface treating assemblages in an easy and reliable manner as well as provides for enhanced surface modifying efficiencies and improvements. | 01-14-2010 |
| 20100048109 | SANDER HAVING REMOVABLE PLATEN - A tool for moving an abrasive media. The tool includes a tool body, a platen, a drive system and a retaining knob. The platen has an exterior platen surface and a knob aperture that is formed through the exterior platen surface. The drive system is housed in the tool body and configured to move the platen. The drive system includes an output member with a first threaded portion. The retaining knob is received through the knob aperture in the exterior platen surface of the platen. The retaining knob has a knob portion, which has an exterior surface, and an attachment member with a second threaded portion that is threadably coupled to the first threaded portion. The platen surface and at least a portion of the knob surface are co-planar. A related method is also provided. | 02-25-2010 |
| 20100120340 | Sander with a balance means - A sander according to the present invention comprising a housing, a motor and a transmission mounted within the housing, a sanding plate mounted below the housing, a battery pack mounted at the rear end of the housing and a balance means mounted on either the housing or the sanding plate.
