...that two musicians were responsible for the invention of color print film? Fascinated by photography, Leopold Godowsky and Leopold Mannes worked together to produce an easy-to-use, practical color film. They worked full time as music teachers and gave concerts while experimenting during their off hours in Mannes' kitchen. Their success earned them full-time, well-paying jobs at Kodak and their efforts resulted in Kodachrome film, which was introduced in 1935.

| 7251571 | Methods of diagnosing open-secondary winding of an ignition coil using the ionization current signal In a first embodiment, the present invention is a method of detecting an open secondary winding, including the steps of enabling an integrator, resetting the integrator, detecting an ionization current, integrating the ionization current over a spark window, compari... | 07/31/2007 |
| 7055372 | Method of detecting cylinder ID using in-cylinder ionization for spark detection following partial coil charging The present feature of the invention comprises a method and apparatus for determining cylinder ID. When a cylinder is compressed, the resistance increases across the spark plug gap. Thus, if a spark coil is only partially charged before activation of the spark, the ... | 06/06/2006 |
| 5331935 | Auxiliary ignition system and method for aircraft engines An auxiliary ignition system comprising a first magneto having a normal operating mode and a start-up mode, and a second magneto having a normal operating mode and a start-up mode. A primary starter switch is operably wired to the first and second magneto... | 07/26/1994 |
| 4903676 | Method and arrangement for improving the starting ability of an internal combustion engine during an engine start The invention relates to a method and an arrangement for improving the starting ability of an internal combustion engine during difficult engine starting conditions that result from cold weather or other external circumstances. Lower than normal engine st... | 02/27/1990 |
| 4442821 | Internal combustion engine ignition method In order to improve the cold starting efficiency of a an internal combustion engines using alcohol or low cetane type fuel, an ignition method provides an ignition mode in which a plurality of energizations of the ignition plugs per cycle is effected duri... | 04/17/1984 |
