20140244141 | USING CAMSHAFT TIMING DEVICE WITH HYDRAULIC LOCK IN AN INTERMEDIATE POSITION FOR VEHICLE RESTARTS - A method of using a mid-position lock VCT phaser in an engine with a stop-start mode of operation with the steps of: when the engine is in a stop mode of the stop-start mode: adjusting a duty cycle of an actuator coupled to the control valve of the phaser to command the control valve to the retard mode; maintaining the duty cycle of the actuator to command the control valve to remain in the retard mode until an automatic restart of the engine. If the key is detected in an off position either restarting the engine; commanding the phaser to the detent mode, such that the lock pin is moved to a locked position and the phaser is locked in an intermediate phase angle position; and shutting down the engine or commanding the phaser to detent mode during engine cranking during a next engine restart. | 08-28-2014 |

20100258095 | Heat exchanger - A heat exchanger has a plurality of intermediate plates arranged one atop the other to form a stack having first and second ends. At least one first fluid channel through conducts a first fluid and at least one second fluid channel through conducts a second fluid. The intermediate plates are geometrically configured to define at least a portion of each of the first and second fluid channels. An end plate is arranged on one of the ends of the stack and a first inlet opening communicates with the first fluid channel for introducing the first fluid and a first outlet opening communicates with the first fluid channel for conducting the first fluid out of the heat exchanger. A second inlet opening communicates with the second fluid channel for introducing the second fluid and a second outlet opening communicates with the second fluid channel for conducting the second fluid away from the heat exchanger. The end plate has at least one expansion zone for reducing the stiffness thereof. | 10-14-2010 |
20130125545 | SYSTEM FOR UTILIZING WASTE HEAT OF AN INTERNAL COMBUSTION ENGINE - A system for utilizing waste heat of an internal combustion engine via the Clausius-Rankine cycle process is provided that includes a circuit with lines containing a working medium, an evaporator heat exchanger which serves for evaporating the liquid working medium using waste heat of the internal combustion engine and which has an inlet opening for conducting the working medium into a flow duct and an outlet opening for conducting the working medium out of the flow duct, and the flow duct is divided into a plurality of flow duct parts connected hydraulically in parallel, an expansion machine, a condenser for liquefying the vaporous working medium, a collecting and compensating vessel for the liquid working medium, it is sought to be able to change the working medium substantially completely from a liquid state of aggregation to a gaseous state of aggregation at an evaporator heat exchanger. | 05-23-2013 |

20130042660 | METHOD AND APPARATUS FOR MAKING COLD-PILGER-ROLLED PIPE - An apparatus for making a cold-pilger-rolled tube has two grooved pilger work rolls rotatable in a roll frame about respective axes to compress a tubular workpiece moving in a travel direction around a mandrel extending in the direction between a nip formed between the grooved rolls and anchored upstream of the nip in a thrust block. An outside diameter of the workpiece is measured downstream in the direction from the rolls as the workpiece passes through the nip, and an actuator engaging one of the rolls relative the other of the rolls shifts it transversely to the travel direction as the workpiece passes through the nip in accordance with the measured outside diameter for maintaining a uniform outside diameter of the workpiece. | 02-21-2013 |
