Abstract: An automatic system for recognizing a shift in basal body temperature indicative of the beginning of a period of infertility combines a device for measurement of urine temperature with a signal processing subsystem. Two specific forms of temperature measurement device are disclosed, and both are adapted for positioning in a toilet bowl.

Abstract: A device for accurately measuring core body temperature by measuring urine temperature is disclosed. The device consists of a sampling chamber including an insulated liquid crystal temperature array which will instantaneously display the temperature of the urine sample therein. The device of this invention is useful as an accurate measurement of the fertility cycles in females, and for the detection of ovulation and pregnancy. The device is also useful in the detection of hypoglycemia, hypothermia and fever.

Abstract: The body of a probe adapted to be immersed in molten metal has a sensor for measuring temperature and a container for taking a sample of the molten metal.

Abstract: In apparatus for picking up a test sample of molten metal or metal alloys and measuring the cooling curve of said sample, comprising a sample receptor and an optical conductor leading from the receptor to a transducer, the receptor is a small, open ended refractory tube having a cavity for receiving the molten sample arranged at the free extremity of a lance with the optical conductor contained within the lance and terminating at the cavity in said receptor and a barrier is disposed between the cavity and the optical conductor, the barrier consisting of a heat resistant, highly thermally conductive material of such quality as to cause the material of the melt sample which is picked up to adhere thereto.
