Haze point measuring system with automatic cooling means

Claim 1

APPARATUS FOR DETERMINING THE SATURATION TEMPERATURE OF A MATERIAL DISSOLVED IN A FLUID, COMPRISING A VESSEL, MEANS INCLUDING A CONTROLLABLE VALVE FOR SUPPLYING A FLUID CONTAINING DISSOLVED MATERIAL TO SAID VESSEL, THE FLUID SUPPLIED BEING AT A TEMPERATURE HIGHER THAN ANY SATURATION TEMPERATURE EXPECTED; MEANS FOR COOLING SAID VESSEL TO THEREBY ALSO COOL THE FLUID THEREIN, SAID COOLING MEANS BEING CONSTRUCTED AND ARRANGED FOR AUTOMATIC ENABLING AND DISABLING THEREOF; MEANS FOR INDICATING THE TEMPERATURE OF THE FLUID IN SAID VESSEL, MEANS ACTING AUTOMATICALLY UPON THE LAPE OF A PRESET, CONSTANT TIME INTERVAL WHICH BEGINS WITH THE OCCURRENCE OF A CERTAIN CONDITION, TO CAUSE CLOSING OF SAID VALVE AND TO ENABLE SAID COOLING MEANS, AND MEANS ACTING AUTOMATICALLY IN RESPONSE TO THE REACHING BY THE DISSOLVED MATERIAL OF ITS SATURATION TEMPERATURE TO CAUSE OPENING OF SAID VALVE AND TO DISABLE SAID COOLING MEANS, THE SAID REACHING OF SATURATION TEMPERATURE ESTABLISHING SAID CERTAIN CONDITION.
