  • Patent number: 11014425
    Abstract: A vehicle condenser which has a substantially parallelepipedic shape and stacked plates, which are parallel to a substantially vertical plane and define alternate coolant chambers and refrigerant chambers between each other. The vehicle condenser is divided into three consecutive groups of refrigerant chambers and includes at least one combination, on one side of the vehicle condenser, of a larger refrigerant outlet, that leads a main flow of refrigerant from one group of refrigerant chambers to a larger refrigerant inlet of a following group of refrigerant chambers, and, vertically opposite to the larger refrigerant outlet, a smaller refrigerant outlet, that leads a residual flow of refrigerant from the one group of refrigerant chambers to a smaller refrigerant inlet of the following group of refrigerant chambers.

  • Patent number: 10193048
    Abstract: The invention relates to an energy recovering assembly (1) and a method of providing the same for extraction of electric power. The assembly comprises a first array (2) of tubes (6) and a second array (3) of tubes (13). The tubes (6) of the first array (2) are interdigitated with the tubes (13) of the second array (3), such that two tubes (13) of the second array (3) are arranged between two successive tubes (6) of the first array (2), or such that two tubes (6) of the first array (2) are arranged between two successive tubes (13) of the second array (3). Thermo electric modules (4) are received in gaps (7) between adjacent tubes (6, 13) of the first (2) and second arrays (3). Fixation arrangements (5) are received in interspaces (X) between two tubes (6; 13).

  • Patent number: 9835079
    Abstract: The invention relates to a method for operating an internal combustion engine (1) provided with at least one working cylinder (3a-3d) each with an associated auxiliary cylinder (5a-5d), which engine (1) is operable in spark ignition and compression ignition modes. Each working cylinder (3a-3d) comprises a working piston (7a-7a) connected to a first crankshaft (9), and each auxiliary cylinder (5a-5d) comprises an auxiliary piston (10a-10d) connected to a second crankshaft (12). The first crankshaft (9) is connected to the second crankshaft (12) to drive the second crankshaft (12) at half the rotational speed of the first crankshaft (9). A device for controlling the phase angle is arranged between the first and second crankshafts. The method involves controlling the phase shift device in order to retain residual exhaust gas and increase the compression ratio.

  • Patent number: 7071830
    Abstract: A sensor for indicating moisture, comprising a unit whose conductivity is dependent on the current moisture exposure and an electric circuit, the unit being included as a component in the electric circuit and the electric circuit being activable by applying an electric field and/or a magnetic field over the same to generate a measurable signal, which is dependent on the total resistance of the circuit. The unit comprises an enzyme together with a substrate, which enzyme is activated when moisture exposure occurs to catalyse a reaction with the substrate that is dependent on the degree of moisture exposure, the substrate reaction product increasing the conductivity of the unit. The invention also relates to the use of such a sensor and a method of using a sensor to indicate moisture.

  • Patent number: 6642016
    Abstract: A biosensor comprises a unit, comprising a substrate and an enzyme, which when brought into contact with the substrate is adapted to affect the substrate so that its conductivity changes as a function of time and temperature, and an electric circuit. The unit is included as a component in said electric circuit and the electric circuit is activable by applying an electric field and/or a magnetic field over the same to generate a measurable signal which is dependent on the total resistance of the circuit. The invention also relates to the use of a biosensor, a label with such a biosensor and a method of indicating the status of a product with such a biosensor.
