Abstract: A refrigerant system selectively operable in a cooling mode, a reheat cooling mode, and a heating mode, includes a primary heat exchanger and a reheat heat exchanger that condition air for a room. In the cooling mode, the primary heat exchanger functions as an evaporator that cools the air, while the reheat heat exchanger is inactive. In the reheat cooling mode, the primary heat exchanger cools the air, and hot refrigerant in the reheat heat exchanger reheats the air to provide dehumidified air at or near room temperature. In the heating mode, the primary heat exchanger functions as a condenser that heats the air, while the reheat heat exchanger is inactive. When the reheat heat exchanger is inactive, a unique venting arrangement prevents the inactive heat exchanger from becoming flooded with liquid refrigerant.

Abstract: A generator for an absorption chiller boils an absorption solution with steam heat by conveying the steam through a tube bundle with the steam flowing counter to the flow of solution. The tube bundle runs downhill in the direction of steam flow, while in some embodiments of the invention a bottom surface of the generator runs uphill in the direction of solution flow. The amount of solution in the generator is kept to an appropriately low level by submerging the tube bundle deeper at one end of the generator than the other.

Abstract: The present invention provides a sensor-fault detection circuit for use with either an inductive or capacitive-type sensor. The sensor-fault detection circuit conducts a test signal into the sensor circuit for testing such sensor circuit. A time difference measuring device is provided to analyze for correct duration of the transit time of a test signal or test pulse, respectively, passing through the sensor. In the event that the transit time does not fall within a predetermined range tolerance, a fault indication can be activated. The circuit can be used, for example, to test an inductive bar-type sensor to determine the speed of a wheel on a vehicle.

Abstract: A web or sheet product is provided which is coated on at least a portion of its surface with a bond-enabling material for adhering toner particles on the surface of the sheet. The sheet product can be used as a mailer or confidential form which is sealed using toner particles as the adhesive. The bond-enabling material may be a polymer which is coated on the sheet as a liquid and then cured to form a film on the surface of the sheet. The bond-enabling material is resistant to melting or degrading when exposed to temperatures used for fusing toner particles, and additionally may act as a tie coat to enhance the adhesion of toner particles to the surface of the sheet. The bond-enabling material may be coated on the peripheral edges of the sheet, and toner particles are printed over the bond-enabling material on the peripheral edges of the sheet. The sheet is folded and sealed by the application of heat and pressure to the edges of the sheet.
