Abstract: A thermal insulation system for mitigating evaporative fuel emissions of an automobile may include a membrane component and a thermal component connected to the membrane component. The thermal component may be configured for condensing, in the membrane component or in the thermal component, fuel vapor generated from a fuel tank of an automobile.

Abstract: A circuit breaker includes: a tripped indicator for indicating a tripping of the circuit breaker, the tripped indicator having a first pivot element mounted on a first pivot pin; and a switch lock with a pawl pivotally mounted on a pawl pin. The first pivot element is actuated by the pawl to indicate a tripped condition of the circuit breaker. The first pivot pin is arranged substantially normal to the pawl pin.

Abstract: The invention relates to a contactor-circuit breaker device (2, 102, 202), comprising: a switch (4) including two pairs of contacts (10, 12) each comprising a stationary contact (14, 16) and a moving contact (18, 20), the stationary contacts (14, 16) being connected in series to an electrical circuit (22), the switch (4) being capable of switching between a closed configuration of the electrical circuit (22) and an open configuration of the electrical circuit (22); a support member (24) for the moving contacts; a current cutoff module (6) able to switch the current from the electrical circuit (22) to the cutoff module (6); and a movement apparatus (26) for moving the support member (24) comprising a armature (44) capable of translating the armature such that the support member switches between the closed configuration and the open configuration through a translational and/or rotational movement.

Abstract: An electrical switch, in particular an electrical circuit breaker, is disclosed including an overcurrent trip device which cuts off the flow of current through the switch in the event of an overcurrent situation. In at least one embodiment, a partial current of the current flowing through the electrical switch flows through a tripping arrangement of the overcurrent trip device and at least one further partial current of the current flowing through the electrical switch is conducted past the tripping arrangement.

Abstract: The present invention provides a circuit and a method for high speed prescaler circuits which utilize pull-down transistors in the critical feedback path. This invention contains a high speed CMOS dual modulus prescaler circuit made up of data or D-flip flops connected serially where the flip-flop positive output Q of stage N is connected to the D-input of the N+1 flip-flop stage. It is also made up of a pull-down field effect transistor. The invention has a clock input which has a frequency known as a circuit input frequency, Fin. The output of this prescaler circuit has an output frequency, Fout. The frequency division which results from this prescaler circuit is a divide by [2 to the power (n+2)] minus 1 if a mode signal equals 1 as opposed to a divide by [2 to the power (n+2)] counter, which results when the mode signal is low.

Abstract: A circuit breaker for breaking current conduction between line and load connectors in response to tripping of a bimetallic thermal element as a result of an over-current condition is disclosed. According to the invention, a trip crossbar is permitted to translate as well as rotate to relieve stress on the thermal element.

Abstract: A trip bar interlock for a circuit breaker characterized by an electrically insulating housing having an apertured bottom wall. A rotatable trip bar is in the housing for releasably holding the circuit breaker in an untripped condition. An actuator is provided for releasing the trip bar when the circuit breaker is dismounted from a mounting surface. The trip bar and the actuator have engaging surfaces and the actuator has an end portion extending through the aperture. The actuator is biased toward the mounting wall.

Abstract: A multipolar type circuit breaker has a plurality of breaker element assemblies corresponding to AC source pole number. Each assembly comprises a contact operating mechanism for ON and OFF operations of a movable contactor connected to a load side terminal with respect to a fixed contactor connected to a current source side terminal. A trip mechanism forms an electric current path between the movable contactor and the load side terminal an interlinks with the contact operating mechanism for releasing its normal ON position latch with respect to the movable contactor upon incoming of a excessive curent to arbitrarity trip ON state. The assemblies are housed in a single housing in a mutually parallel and aligning relation. The contact operating mechanisms in all assemblies are operated by a single handle extending transversely to them within the housing.

Abstract: The following specification describes a circuit breaker trip crossbar having diverging radial surfaces receiving a tapered rail therebetween. The rail extends from the bottom edge of the conventional breaker barrier wall recess and forms a small area pivot adjacent the crossbar axis to reduce the torque required to pivot the bar and to render the torque reproducible for calibration purposes.The radial surfaces are economically formed by flat mold surfaces in opposite mold halves to avoid mold flash in the pivot area while enabling one of the mold halves to conventionally form the latch plate securing hole in the crossbar.

Abstract: A multi-pole excess current circuit breaker assembly has a plurality of single-pole circuit breakers. In each of the latter the electric contacts are openable by a spring-loaded tripping mechanism actuated by a release lever as the release lever is moved from a first position to a second position by an excess current responsive device. The actuated tripping mechanism moves the release lever from the second position to a third position.
