Photosensitive apparatus and method for the continuous measurement of the fibrous mass of a textile fibre sliver

Claim 1

AN APPARATUS FOR DETERMINING THE FIBROUS MASS OF A TEXTILE FIBRE SLIVER COMPRISING A GUIDE CHANNEL INTERPOSED IN THE PATH OF THE SLIVER FOR COMPACTING THE SLIVER PASSING THERETHROUGH, SAID GUIDE CHANNEL HAVING A PAIR OF OPPOSED APERTURES ON OPPOSITE SIDES OF THE PATH OF THE SLIVER, AN ADJUSTABLE SHUTTER POSITIONED ADJACENT SAID GUIDE CHANNEL, A HIGH-INTENSITY STROBOSCOPIC LAMP DISPOSED RELATIVE TO SAID GUIDE CHANNEL AND SAID ADJUSTABLE SHUTTER FOR PASSING HIGH-INTENSITY RADIATION IMPULSES OF SHORT DURATION THROUGH SAID GUIDE CHANNEL APERTURES TO IRRADIATE THE COMPACTED SLIVER AND SAID ADJUSTABLE SHUTTER, AND AT LEAST A PAIR OF PHOTOELECTRIC CELLS FOR PRODUCING SIGNALS IN RESPONSE TO LIGHT RECEIVED THEREON FROM SAID LAMP, AT LEAST ONE OF SAID PHOTOELECTRIC CELLS BEING DISPOSED RELATIVE TO SAID GUIDE CHANNEL FOR RECEIVING LIGHT PASSING THROUGH SAID GUIDE CHANNEL APERTURES, AND ANOTHER OF SAID PHOTOELECTRIC CELLS BEING DISPOSED RELATIVE TO SAID ADJUSTABLE SHUTTER FOR RECEIVING LIGHT PASSING THROUGH SAID ADJUSTABLE SHUTTER, MEANS OPERATIVELY CONNECTED TO SAID PHOTOELECTRIC CELLS FOR RECEIVING THE PRODUCED SIGNALS THEREFROM, SAID MEANS INCLUDING AN IMPULSE AMPLIFIER AND AN IMPULSE INTEGRATOR SEQUENTIALLY CONNECTED TO EACH OTHER FOR COORDINATING AND CONVERTING THE DIFFERENTIAL OF THE RECEIVED PRODUCED SIGNALS INTO A SINGLE CONTINUOUS SIGNAL WHEREBY THE MASS OF THE SLIVER PASSING THROUGH SAID GUIDE CHANNEL CAN BE DETERMINED.
