Title: Sistema óptico de muy alta flexibilidad para el ajuste del campo de la iluminación en luminarias y dispositivos de alumbrado
Inventor: SEOANE PENA JOSE LUIS
IPC: F21V5/04
Filed: 2010-07-08
Granted: 2014-03-11
Abstract: La invención ?Sistema óptico de muy alta flexibilidad para el ajuste del campo de la iluminación en luminarias y dispositivos de alumbrado?, describe un sistema de lentes cilíndricas compuesto por dos o varios conjuntos de lentes que se pueden desplazar entre sí para ser incorporado en luminarias y dispositivos de iluminación. Cuando se usa el primer conjunto de lentes, esto posibilita ajustar el campo de iluminación en una sola dirección del espacio. Cuando se usa el segundo conjunto montado a 90º, se consigue ajustar el campo de iluminación en la dirección perpendicular. Cuando un conjunto es rotado en referencia al otro, se consiguen ajustes del campo de iluminación complejos.#La ventaja que aporta esta patente es la conseguir a partir de un haz de rayos colimados, el ajuste del campo de iluminación a voluntad e independientemente en las dos direcciones del espacio sin necesidad de recurrir a pantallas y por lo tanto sin perder rendimiento luminoso.

Title: Key and Disc Tumbler Cylinder Lock
Inventor: MARTIKAINEN KAARLO
Filed: 2007-06-19
Granted: 2010-11-03
Abstract: The invention relates to a disc tumbler cylinder lock and a key for it .The key according to the invention comprises a groove (6) that is transverse to the key shank (2). The groove comprises a bottom section (6A) and side sections (6B) that are transverse to the bottom section between the bottom section and the outer surface (2A) of the key shank.

If the carriage speed is too slow, the nominual speed value stored in a read only memory lock-up table is incremented by a fixed value i.e. plus one, two, or three units).  If the speed is two fast, the nominal speed value is decremented by a fixed value i.e. minus one, two or three units).
