...that the Band-Aid Bandage was invented by a Johnson & Johnson employee whose wife had cut herself? Earl Dickson's wife was rather accident prone, so he set out to develop a bandage that she could apply without help. He placed a small piece of gauze in the center of a small piece of surgical tape, and what we know today as the Band Aid bandage was born!

| 7737596 | Anti-cogging apparatus for permanent magnet electrical machines The present invention provides cancellation of cogging torque of a permanent magnet electrical machine using two sets of magnetic elements, one set is mechanically coupled to the stator with the other set being mechanically coupled to the rotor of the machine. At le... | 06/15/2010 |
| 7288865 | Bicycle generator hub A bicycle generator hub is mounted to the front fork of a bicycle and includes a hub shaft, a hub shell, bearings, a generator mechanism and first and second magnetic flux recirculation members. The hub shaft is non-rotatably mounted to the front fork. The hub shell... | 10/30/2007 |
| 7211922 | Rotor for rotating electric machine The present invention provides a dynamoelectric rotor enabling electromagnetic noise to be reduced by linking a facing tip end portion and root end portion of adjacent claw-shaped magnetic poles by a linking member and placing a field winding in contact with an inne... | 05/01/2007 |
| 7109630 | Electric rotating machine and manufacturing process thereof In an electric rotating machine, a rotor can be manufactured relatively easily at reasonable cost without high working accuracy for pole cores, and a permanent magnet can be assembled without impairing cooling efficiency of the rotor. A magnet-holding member 7 | 09/19/2006 |
| 6891295 | Flywheel magneto generator A flywheel magneto generator which comprises a rotor having a magnet attached to an outer circumferential side of a flywheel and a stator constructed by winding a generating coil around a core having a magnetic pole portion opposed to a magnetic pole of the rotor, w... | 05/10/2005 |
| 6724116 | Alternator permanent magnet rotor design A rotor assembly for an alternator includes an electrical wire defining an excitation winding. A first pole piece and a second pole piece each have a generally circular body defining an axis of rotation and an outer radial periphery. A plurality of pole fingers are ... | 04/20/2004 |
