Abstract: An altitude compensating turbocharger wastegate control system operates by bleeding air from an intake air line extending from an intake manifold of an engine to a wastegate actuator to raise the intake manifold pressure at which the wastegate is opened when the engine is operating at high altitudes. The control system operates in response to a comparison of barometric air pressure sensed by a pressure sensor and a number of predefined ranges of sensed pressure in a memory of an engine controller to determine whether no, full, or an intermediate amount of bleeding should take place in order to maintain the desired turbocharger output at high altitudes.

Abstract: A method of reducing turbo lag in a compression ignition engine having an exhaust gas recirculation system (EGR) and a variable geometry turbocharger (VGT). The method includes the steps of determining an intake manifold pressure and intake manifold mass airflow setpoint, MAPd and MAFd, as a function of the current engine speed and requested fueling rate (Wf,REQ). The method further includes modifying the setpoints by a transient governor to generate modified setpoints, MAFc and MAPc, as a function of MAFd and MAPd, respectively, and feeding the modified setpoints to the controller to drive the turbocharger and EGR valve to the desired setpoints, thereby maximizing the amount of fresh air admitted to the engine during transient operation. Another embodiment of the method for reducing turbo lag coordinates the controller gains between the EGR and VGT. The method speeds up the MAF response by using multivariable control of both the EGR and VGT to aggressively regulate airflow to the desired setpoint.

Abstract: The invention relates to a method and an apparatus for the conversion of low-grade heat into mechanical energy, in particular electricity. To this end a working medium is heated in a closed circulation system causing the working medium to expand. The expansion produces mechanical energy. The heat remaining in the working medium is abstracted by a cooling medium in counterflow, to be reutilized for the production of mechanical energy. This makes its possible to achieve a high degree of efficiently. Due to cooling the working medium contracts and this contributes to the achievement of a high degree of efficiency. The working medium is preferably a paraffine.

Abstract: A self-heating or self-cooling container has a container body, a closure at one end of the body through which the contents of the container can be consumed, and a thermic module at the other end of the body having an actuator portion and an elongated reaction chamber portion that extends distally into the container body and contains a liquid reactant relatively more distally from the actuator portion than a solid reactant separated from the liquid reactant by a breakable barrier. When a user actuates the thermic module, an elongated actuator member punctures the barrier. The user can then immediately invert the container, allowing the liquid reactant to drain through the puncture into the solid reactant in the reaction chamber. The reactants mix and produce a reaction that, depending upon the reactants, either heats or cools the container contents by conduction through the thermic module wall. An advantage is that the user does not need to wait to invert the container after actuating it.

Abstract: A rupture disk for a refrigeration unit that, upon bursting, does not interfere with the operation of a downstream, normally closed, mechanical relief valve. The disk is designed to rupture at predetermined pressure and is made of a compressed powder or an organic wax that dissolves in the refrigerant. The process side of the disk, i.e. the side facing the evaporator, is covered with a film that is impermeable to the particular halocarbon refrigerant in use. Upon rupture, fractures from a disk that is made of compressed powder readily pass through a downstream mechanical relief valve because the fragments are small and have a uniform geometry. Upon rupture, fractures from a disk that is made of organic wax readily pass through a downstream mechanical relief valve because they have all or partially dissolved in the halocarbon refrigerant.

When an electric vehicle is at rest after the heating operation to charge its secondary battery with an electric power from an external power source, the control unit first starts a defrosting operation and starts a charging operation of the secondary battery after the completion of the defrosting operation.

Abstract: A porous body 4 and a first immersing solution 6 are put in a vessel 5 in proportions such that the whole of the porous body 4 is immersed in the immersing solution, and the immersing is conducted for an arbitrary period of time. The vessel 5 is formed so as to have a depth greater than the height of the porous body 4. A vessel-capacity changing device 7 is inserted in the vessel 5. The first immersing solution 6 overflows from the interstice between the vessel-capacity changing device 7 and the vessel 5. A second immersing solution 8 is poured through a charging port, and simultaneously the vessel-capacity changing device 7 is lifted to thereby remove the same from the immersing solution. Thus, the porous body 4 is immersed in the second immersing solution 8 without being exposed to the outside air to thereby complete solution replacement. The immersing of the porous body can be effected safely, securely and at a lowered cost without damaging the porous body.

Abstract: The technique for electronically resetting a magnetically sealed solenoid to an unattracted, unactuated position is described for use with solenoids which have either a residual magnetic or a permanent magnet holding force necessary to retain the armature of the solenoid in its actuated position until such time as the armature is either physically displaced by a mechanical force or an electronic signal is applied to the solenoid. This displacement creates a reverse polarity magnetic field, effectively overcoming the magnetic field acting to hold the armature in its actuated position, permitting a small mechanical force to reset the armature. In order to prevent a lock or similar device from being conditioned for opening and possibly left in that condition for a significant period of time while unattended, jeopardizing the security of the container and its contents, the actuation of the armature in the reset or release phase may occur a relatively short time following its actuation.
