20130162378 | POWER CIRCUIT BREAKER - A power circuit breaker is disclosed wherein an electric current is monitored by an electronic trip unit in order to detect an electrical fault. In an embodiment, a first magnetic device of the power circuit breaker, in the event of a fault being detected, is configured to be excited which, when it is excited, trips a trip mechanism via a plunger. As a result of tripping, the trip mechanism disconnects two contacts via which the current flows. The power circuit breaker of an embodiment includes a second magnetic device which is likewise able to be excited by the ETU and by which the trip mechanism is likewise able to be tripped. | 06-27-2013 |
20130213779 | ELECTRICAL SWITCH - An electrical switch is disclosed, including a switch housing and a busbar routed through a housing opening in the switch housing. In at least one embodiment, a contact element is present for making electrical contact with the busbar, the contact element being clamped in between the busbar and the switch housing in the housing opening. | 08-22-2013 |

20130215545 | ELECTRIC SWITCH - An electric switch is disclosed, in particular an electric circuit breaker. In at least one embodiment, the switch includes a measuring channel for measuring an electric measured variable and is switched off when the result of a measurement reaches or exceeds a limit value. To test the mode of operation of the measuring channel, the electric measured variable is switched to a reference channel and a reference signal source is switched to the measuring channel and the reference result obtained via the reference channel is compared with a reference setpoint. The switch is also tripped if, to test the mode of operation of the measuring channel, the electric measured variable is switched to the reference channel and the result obtained via the reference channel reaches or exceeds the limit value. | 08-22-2013 |

20100275543 | Polymeric Fiber Insulation Batts for Residential and Commercial Construction Applications - Fiber insulation batts suitable for building thermal insulating applications are made using polymer fibers. A mixture of staple fibers and binder fibers are used to make the batt. The batt has a bulk density of 5-15 kg/m3, a thermal conductivity of 30-50 mW/m-K and a lambda*density value of from 250-550. The batts can be made by forming a web of the fibers, and calibrating and heat-setting the web. The web can be formed using pneumatic or mechanical carding processes. In some processes, the batt can be made by forming a stack of multiple plies of the web and calibrating and heat-setting the stack. | 11-04-2010 |
