    Abstract: The present invention provides an automated chemical drain system which includes a buffer tank for collecting used chemical from a process machine, at least two level sensors in the buffer tank for sensing a fluid level and sending out a signal, a controller for receiving the signal from the level sensors and then sending out a second signal to a solenoid controlled valve when the first signal exceeds a threshold value, a solenoid controlled valve that is in fluid communication with the buffer tank and a collection tank, and a collection tank for collecting used chemical from the buffer tank. The collection tank may further be provided with a weight sensing device such that a signal may be sent out to the controller when the weight of the collection tank exceeds a maximum allowable value so that the controller shuts off the solenoid controlled valve to avoid overflow in the collection tank and to alert a maintenance operator to empty the collection tank.

    Abstract: A thermocouple formed of a length of a single composition having first solid phase section adjoining a second solid phase section, and a transition therebetween. One method of making such thermocouples is to raise the temperature of the first solid phase section above its transformation temperature while maintaining the temperature of a second adjoining solid phase section of the length of material below its transformation temperature. A second method includes rapidly solidifying a molten material by contacting it with a moving substrate formed of adjoining regions of differing thermal conductivity. A third method includes rapidly solidifying a molten material by alternatingly contacting it with a cooling fluid and air. A fourth method includes transforming a section of a length of material in a first solid to a second solid phase by mechanical means.
