20090126705 | Heated fuel vaporizer for enhanced cold starting of an internal combustion engine - A heated fuel vaporizer is disposed in an intake component, such as a throttle valve or an intake manifold, of a fuel injected and spark-ignited internal combustion engine. The engine may be fueled by any liquid fuel, such as gasoline, diesel or by fuels much less volatile than gasoline, for example, alcohols such as ethanol, or mixtures of ethanol and gasoline. A configurable heating element is made from a single piece of sheet metal and includes one or two grids each formed by slots and segments. By controlling the geometry of the element, the power and surface area can be configured to any desired value. A single piece heater assembly is designed for installation in an intake component, such as throttle valve or intake manifold, of an internal combustion engine. The heater assembly includes a single-grid or dual-grid heating element that is over-molded with a high melting temperature polymer. | 05-21-2009 |

20090065338 | CIRCUIT BREAKER FOR MOTOR PROTECTION AND/OR LINE PROTECTION - A manually operated circuit breaker for motor protection and/or line protection includes a basic board including a switching mechanism, a contact device, and a main current path. The switching mechanism includes a switching apparatus and a breaker latching mechanism. The circuit breaker includes a manual actuating device disposed in a housing part protruding from an operating front and configured to activate the switching mechanism via a rotary knob and an actuating shaft disposed perpendicular to the operating front. The circuit breaker includes an electronic control unit module pluggable onto the basic board and configured to be set with at least one control variable for a fault scenario so as to activate the switching mechanism by indicating a settable fault scenario. The electronic control unit is supplied with a voltage from the main current path via the contact device. An actuator unit including an energy storing device is configured to activate the breaker latching mechanism, and a tripping element is configured to respond to a settable fault criterion. | 03-12-2009 |
20090167468 | ELECTRICAL CIRCUIT BREAKER HAVING A PROTECTIVE FUNCTION - An actuating unit or actuating mechanism and release for a circuit breaker. The magnetic mechanism of the release includes a magnet armature, which can move linearly in a magnet coil, is in the form of a tripping plunger and can be moved towards a permanent magnet counter to the force of a storage compression spring and is held fixedly by said permanent magnet in the case of a magnet coil through which no current is flowing. The tripping unit is in the form of a mechanical force store. After a tripping action, the mechanical force store needs to be reset manually again. For this purpose, a rotary movement of the drive shaft with an angular displacement of from 20 to 30 degrees takes place in the opposite direction to the ON switching rotary movement. | 07-02-2009 |
20110297518 | TRIPPING UNIT FOR CIRCUIT BREAKER - A multipolar circuit breaker includes main circuits having main contacts and a latching mechanism for tripping the main contacts of main circuits. A tripping unit configured to actuate the latching mechanism in response to detection of an over-current in at least one of the main circuits. The tripping unit is plugged into a section of the circuit breaker and includes at least one bimetal strip connected in series with at least one of the main circuits and operatively connected with the latching mechanism. | 12-08-2011 |
20110298576 | TRIPPING UNIT FOR CIRCUIT BREAKER - A tripping unit is configured to send an electrical tripping-signal to a switching unit of a circuit breaker so as to trip main contacts of main circuits of the circuit breaker in response to a detection of a current being above a predetermined level in at least one of the main circuits. The tripping unit includes a fuse configured to be connected in series to a main circuit of the circuit breaker and a detection unit connected in parallel with the fuse and configured to generate the tripping signal for the switching unit in response to the fuse being blown. | 12-08-2011 |
