An apparatus for controlling illumination of a fluorescent lamp is disclosed which includes two transformers for heating cathodes of the fluorescent lamp. Also included are two ballasts for ballasting the fluorescent lamp having an input adapted to receive a source of A-C power and an output coupled to the fluorescent lamp. The ballasts provide power to the fluorescent lamp in excess of a normal rated power of the fluorescent lamp. The apparatus further includes a flasher relay for repeatedly cycling power at a cycling rate between power on and power off to the fluorescent lamp coupled to the output of the ballasts and to the fluorescent lamp, thereby causing the fluorescent lamp to flash at a flashing rate with a flashing intensity of light output which is greater than the flashing intensity of output of the fluorescent lamp under normal continuous operation. A remote control sensor may be connected to the apparatus to switch the apparatus between the flashing cycle and normal continuous operation. The remote control sensor may also be used to the control the flashing rate of the flasher relay. An audio modulation apparatus may also be operatively connected to the flasher relay to control the flashing rate of the apparatus with an audio signal.

A shredder for cutting carbon paper of the type used for credit purchases into indescernible pieces by a high speed cutting blade safely located within an enclosed housing having a lower collection receptacle. A pair of feed rolls moves the carbon paper at a controlled rate through a chute generally perpendicularly into the horizontal cutting path of the blade. One of the feed rolls is power driven by an electric motor. A single push button having a pair of indicating lights controls the drive motors for the blade and for the feed rolls. Depressing of the button while the blade is rotating reverses the blade and feed roll rotation to prevent jamming. Once actuated a timing circuit maintains the blade rotating for generally 10 seconds. A magnet is mounted on the collection receptacle closely adjacent a magnetic switch to provide a safety interlock to prevent the blade motor from being energized when the cover is removed from the collection receptacle. The invention also encompasses a method for shredding carbon paper.
