Abstract: A vehicle heat exchanger includes a first end tank, a second end tank opposite the first end tank, and a main core between and connecting the first and second end tanks. The main core includes a heat exchanger element including a plurality of tubes in fluid communication with the first and second end tanks. At least two control elements are operatively positioned in one or more housings that are operatively connected to the vehicle heat exchanger.

Abstract: A method for locating electrical short circuits in an electronic substrate containing a plurality of conductive paths. A pair of shorted paths is identified and a current signal is applied thereto. Simultaneously, the voltage across the shorted paths is measured. The current signal is then increased in incremental steps until the voltage starts to vary nonlinearly with respect to the current signal. A temperature differential is then created between the substrate as a whole and small sectors of the substrate until the measured nonlinear relationship between current and voltage reverses in the direction of resuming a linear relationship. The small sector which caused the voltage to respond to the temperature differential is then identified, thereby identifying the approximate location of the short circuit.

Abstract: A returnable shipping box for large pieces of furniture arranged for convenient inspection of the furniture just before final packing at a shipping point and during the first stages of unpacking at a receiving station. The box includes a wooden base to which is attached a first foldable panel which folds into a position covering the front and sides of the furniture piece. A second foldable panel also attached to the base folds into a similar position covering the back and sides of the furniture. Both first and second panels are provided with sides and a top which nest together when the box is closed.
