Electric infrared emitter

Claim 1

AN ELECTRIC INFRARED RADIATION EMITTER COMPRISING A PLURALITY OF SUBSTANTIALLY PARALLEL RADIATION PERMEABLE TUBES OF A MATERIAL SELECTED FROM THE GROUP CONSISTING OF OPAQUE QUARTZ WARE, QUARTZ GLASS AND HIGH MELTING POINT GLASS, SAID TUBES BEING FUSED TOGETHER AT A PLURALITY OF POINTS ALONG THEIR ADJACENT SURFACES, EACH TUBE HAVING ONE END FUSED TOGETHER WITH A SIMILAR END OF ANOTHER TUBE TO DEFINE A COMMON PASSAGE BETWEEN SAID TUBES, SAID TUBES BEING BENT AT A LOCATION INTERMEDIATE TO THEIR FUSED ENDS AND THEIR OPPOSITE ENDS TO POSITION THE LENGTH PORTIONS OF SAID TUBES BETWEEN THEIR FUSED ENDS AND THE BENDING LOCATION AT A PREDETERMINED ANGLE WITH RESPECT TO THE REMAINING LENGTH PORTIONS OF SAID TUBES, AN ELECTRICAL RESISTANCE HEATING COIL DISPOSED WITHIN EACH OF SAID TUBES FOR EXTENSION THEREIN, SAID HEATING COIL BEING APPROXIMATELY EQUAL IN DIAMETER TO THE INTERNAL DIAMETER OF ITS ASSOCIATED TUBE, AND AN ELECTRICAL CONDUCTOR EXTENDING THROUGH SAID PASSAGE AND CONDUCTIVELY CONNECTING SAID HEATING ELEMENTS TOGETHER IN SERIES EACH HEATING COIL HAVING A LEAD CONDUCTOR EXTENDING FROM THE END OF ITS ASSOCIATED TUBE REMOTE FROM THE FUSED END THEREOF AND DISPOSED FOR CONNECTION TO AN EXTERNAL SOURCE OF ELECTRICITY FOR ENERGIZATION OF THE HEATING COIL THEREBY TO GENERATE AND EMIT INFRARED RADIATION.
