Abstract: A mounting adaptor is disclosed for removably securing an interior rearview mirror assembly to a mounting support on the inner surface of a vehicle window such as a windshield. The adaptor preferably has a recessed channel on one side for receiving a window mounting button and a projection on the opposite surface simulating a window mounting button for removably mounting a rearview mirror assembly. The projection may be shaped to receive the same or a different mirror assembly channel mount as compared to the support on the window to allow conversion from one assembly to another without changing the window support. The adaptor may also include a support for a vehicular accessory such as a microphone, compass, headlight dimmer, light, moisture sensor, radar detector or the like.

Abstract: In a rotary fan (10) having a tubular drive shaft (14) and a lower cylindrical hub (16), an isolator bushing (20) interconnects the drive shaft (14) and hub (16) so as to substantially reduce vibrations. The bushing (20) is elastomeric, tapered and mounted within the hub (16) in an uncompressed state to maintain vibration-reducing properties. The drive shaft (14) extends into and terminates within a central bore (42) of the bushing (20), and the end portion of the shaft (14) is secured at a lower portion of the bushing (20). The hub (16) is secured to an upper end surface of the bushing (20) and the length of the bushing (20) provides dampening of vibrations caused by rotary motion. The tapering of the bushing (20), while maintained in an uncompressed state, provides dampening of vibrations caused by resonant frequency characteristics.

Abstract: Apparatus as for use on a sewing machine, employing a stock pivoting and advancing platform for directionally guiding while advancing stock relative to a reference point during performance of an operation on said stock, the operation being therefore in a controlled pattern. Normally, a working tool such as a stitching needle, is at the reference point. The stock is incrementally advanced while repeatedly and incrementally being pivoted by the special platform in response to sensing of the pattern such as an edge of the stock. In use on a sewing machine, both the advancement and the pivoting are conducted while the stitching needle penetrates the material.
