Egg blood detector including means to determine if the egg is too dense to accurately candle

Claim 1

AN APPARATUS FOR DETERMINING THE PRESENCE IN A MIXTURE OF A SUBSTANCE HAVING A CONCENTRATION IN EXCESS OF A PREDETERMINED LEVEL, SUCH MIXTURE BEING ADAPTED TO PASS THERETHROUGH ENERGY OF A FIRST WAVE LENGTH WHICH IS ATTENUATED BY THE PRESENCE OF SAID SUBSTANCE AND OF A SECOND WAVE LENGTH THE INTENSITY OF WHICH IS SUBSTANTIALLY UNAFFECTED BY THE PRESENCE OF SUCH SUBSTANCE IN THE MIXTURE AND WHICH MIXTURE IN ANY PARTICULAR SAMPLING THEREOF MAY PERMIT AN AMOUNT OF ENERGY TO PASS THERETHROUGH MAKING DETERMINATION BY THE APPARATUS AS TO THE PRESENCE OR ABSENCE OF AN EXCESSIVE LEVEL OF THE SUBSTANCE IN SUCH PARTICULAR SAMPLING UNRELIABLE, A PAIR OF SENSING DEVICES ARRANGED TO RECEIVE ENERGY AT SUCH FIRST AND SECOND WAVE LENGTHS AFTER TRANSMISSION THEREOF THROUGH SUCH MIXTURE AND RECEIVED, CIRCUIT MEANS INCLUDING SAID SENSING DEVICES AND COMPRISING A SIGNAL GENERATING NETWORK OPERATIVE TO GENERATE A SIGNAL WHEN THE OUTPUT OF SAID SENSING DEVICE RECEIVING SAID FIRST WAVE LENGTHS EXCEEDS A PREDETERMINED LEVEL AND THEREBY REPRESENTS THE PRESENCE IN ANY SAMPLING OF THE MIXTURE OF SUCH SUBSTANCE IN A CONCENTRATION THEREOF EXCEEDING SUCH PREDETERMINED LEVEL, AND COMPARATOR CIRCUITRY CONNECTED WITH SAID SENSING DEVICE RECEIVING SAID SECOND WAVELENGTH FOR COMPARING THE OUTPUT THEREOF WITH A PREDETERMINED REFERENCE AND FOR ENERGIZING SAID SIGNAL GENERATING NETWORK WHENEVER SUCH A PARTICULAR SAMPLING OF THE MIXTURE PASSES ENERGY THERETHROUGH IN AN AMOUNT MAKING DETERMINATION OF THE PRESENCE OR ABSENCE OF AN EXCESSIVE LEVEL OF THE SUBSTANCES IN SUCH SAMPLING UNRELIABLE.

Claim 2

AN APPARATUS FOR DETERMINING THE PRESENCE IN A MIXTURE OF A SUBSTANCE HAVING A CONCENTRATION IN EXCESS OF A PREDETERMINED LEVEL, SUCH MIXTURE BEING ADAPTED TO PASS THERETHROUGH ENERGY OF A FIRST WAVE LENGTH WHICH IS ATTENUATED BY THE PRESENCE OF SAID SUBSTANCE AND OF A SECOND WAVE LENGTH THE INTENSITY OF WHICH IS SUBSTANTIALLY UNAFFECTED BY THE PRESENCE OF SUCH SUBSTANCE IN THE MIXTURE AND WHICH MIXTURE IN ANY PARTICULAR SAMPLING THEREOF MAY PERMIT AN AMOUNT OF ENERGY TO PASS THERETHROUGH MAKING DETERMINATION BY THE APPARATUS AS TO THE PRESENCE OR ABSENCE OF AN EXCESSIVE LEVEL OF THE SUBSTANCE IN SUCH PARTICULAR SAMPLING UNRELIABLE, A PAIR OF SENSING DEVICES ARRANGED TO RECEIVE ENERGY AT SUCH FIRST AND SECOND WAVE LENGTHS AFTER TRANSMISSION THEREOF THROUGH SUCH MIXTURE AND RECEIVED, CIRCUIT MEANS INCLUDING SAID SENSING DEVICES AND COMPRISING A SIGNAL GENERATING NETWORK OPERATIVE TO GENERATE A SIGNAL WHEN THE OUTPUT OF SAID SENSING DEVICE RECEIVING SAID FIRST WAVE LENGTHS EXCEEDS A PREDETERMINED LEVEL AND THEREBY REPRESENTS THE PRESENCE IN ANY SAMPLING OF THE MIXTURE OF SUCH SUBSTANCE IN A CONCENTRATION THEREOF EXCEEDING SUCH PREDETERMINED LEVEL, AND COMPARATOR CIRCUITRY CONNECTED WITH SAID SENSING DEVICE RECEIVING SAID SECOND WAVELENGTH FOR COMPARING THE OUTPUT THEREOF WITH A PREDETERMINED REFERENCE AND FOR ENERGIZING SAID SIGNAL GENERATING NETWORK WHENEVER SUCH A PARTICULAR SAMPLING OF THE MIXTURE PASSES ENERGY THERETHROUGH IN AN AMOUNT MAKING DETERMINATION OF THE PRESENCE OR ABSENCE OF AN EXCESSIVE LEVEL OF THE SUBSTANCES IN SUCH SAMPLING UNRELIABLE.
