Abstract: A detachable and replaceable ion source for a mass spectrometer. The ion source comprises a housing which defines an ion source chamber, an ion source mounting means complementary to mounting means on the mass spectrometer to detachably couple with the mass spectrometer. This allows movement of the housing to bring the ion source chamber into a position of use at the inlet of said mass spectrometer and to take the ion source chamber from said position of use into a retracted position. Sealing means is provided to create an air tight seal between the housing and the mass spectrometer when the ion source chamber is in its position of use. A release mechanism is provided which cooperates with the mass spectrometer to allow the said movement of said housing.

Abstract: A light assembly for an automotive vehicle includes a lens holder that supports an internal lens. The light assembly includes a light source powered by the vehicle. The internal lens includes a first surface having a plurality of protrusions. The protrusion scatter and diffuse heat emitted from the light source away from an outwardly positioned reflex lens and an outer lens. The protrusions also reflect light toward a reflector to increase the overall brightness observed coming from the light assembly.

Abstract: A light assembly for an automotive vehicle includes a lens holder that supports an internal lens. The light assembly includes a light source powered by the vehicle. The internal lens includes an undulating surface facing the light source. A reflective metallic layer is disposed along the undulating surface to provide enhanced scattering of light and heat away from a reflex lens.
