Title: Temperature sensor
Inventor: NADEN JAMES M
IPC: G01K5/52
Filed: 1990-08-03
Abstract: Temperature Sensor Abstract of the Disclosure A temperature sensor comprises a Fabry-Perot cavity formed between one end of a sinyle mode fiber and the surface of a silicon reflector.  The Reflector is formed as one sidewall of a channel in a block of silicon, the other sidewall of the channel being of lesser height from the base of the channel.  A groove formed in the top of the other sidewall of the channel provides an anchorage for the end of the fiber. Modulated light from a laser is propagated down the fiber and changes of temperature alter the optical path length of the cavity.  The light reflected in the fiber will form interference fringes which are detected and used to determine the temperature changes.

Inventor: KISER THOMAS E
IPC: F24F3/044
Filed: 1992-04-30
Abstract: In an industrial building housing a production operation utilizing a liquid material exposed to the atmosphere, a relationship is maintained between the plant atmosphere and the liquid material whereby the atmosphere is not receptive to vaporized or atomized portions of the liquid. The building is maintained under a slight positive pressure throughout to prevent random and uncontrolled infiltration of outside atmosphere. The temperature and relative humidity of the building atmosphere and the temperature of the liquid are closely monitored and maintained at levels relative to one another which assure that the building atmosphere is not receptive to evaporated or atomized liquid. Air handling units for supplying conditioned air to the building interior include heat exchangers and evaporators for regulating the wet bulb and dry bulb temperatures of the air being admitted to the building interior, and thus the temperature and relative humidity of the atmosphere within the building. The liquid material recirculates through a heat exchanger for removal of accumulated heat as necessary to maintain it at a temperature relative to the dry bulb/wet bulb temperatures of the building atmosphere below that at which it would tend to migrate by vaporization or atomization into the building atmosphere.
