Lens

This lens is utilized in conjunction with a light source to indicate the condition or mode of operation of related apparatus.

The device consists of a block of translucent material 2, including a slot 4. In ordinary operation, the translucent lens carries information on its face 6. The information is communicated to a machine operator by the activation of a light source, not shown, behind the lens.

Alternatively, this lens can be used with a dual light source indicative of two independent bits of data. For this mode of operation, a heat resistant opaque member is inserted into slot 4, allowing either the upper or the lower half of the lens to be independently illuminated. The division between upper and lower portions which can be independently illuminated is indicated by the dotted line on face 6.
