20140232510 | THERMO MAGNETIC TRIP UNIT FOR A CIRCUIT BREAKER AND CIRCUIT BREAKER - A thermo magnetic trip unit is disclosed for a circuit breaker, in particular for a molded case circuit breaker. In an embodiment, the thermo magnetic trip unit includes a braid plate, a load plate and a heater arranged between the braid plate and the load plate, whereby the braid plate, the load plate and the heater form a current path. In an embodiment, the thermo magnetic trip unit further includes a bimetal positioned on the heater, a rotatable trip bar and an energy storage spring, whereby the trip bar can release the energy storage spring after being touched by the bimetal with certain power. Further, the bimetal is an arched or curved snap action bimetal which snaps over to an opposite direction as soon as a certain temperature is reached. Further, a circuit breaker, in particular molded case circuit breaker, including such thermo magnetic trip unit, is disclosed. | 08-21-2014 |

20140020599 | ADDITIVE TO MODIFY THE RHEOLOGICAL PROPERTIES OF ASPHALT, TO BE USED IN WARM ASPHALT MIXTURES - It is an additive that modifies the Theological properties of asphalt under warm conditions, and makes it possible to mix and compact asphalt mixtures with a reduction in temperature of up to 35° C., which is constituted by wax, an adhesion-improving additive and a fluxing agent, which reduces asphalt oxidation, causing it to be less-aged and more resistant to fatigue, reduces the interfacial tension between the aggregate and the asphalt, increases adhesion between them, making the mixture resistant to the damages caused by humidity, increases resistance to permanent deformation, causes gas emissions to be reduced and leads to savings in fuel consumption. The additive according to the invention has the following effects:—At high temperatures (between 100° C. and 160° C.), IT REDUCES the asphalt viscosity, as compared to asphalt without the additive.—At temperatures between 58° C. and 82° C., IT INCREASES the asphalt viscosity, as compared to asphalt without the additive.—At temperatures lower than 25° C., IT REDUCES the asphalt viscosity, as compared to asphalt without the additive. | 01-23-2014 |

20090200132 | Friction clutch - A pull-type friction clutch having an annular part that is axially clamped to a disk spring and is axially fixedly connectable to an actuation sleeve of an actuation system. The annular part has axially raised lugs on its face bearing against the disk spring, and the lugs engage in slots that are provided between the disk spring tongues where the tongues are appropriately widened, to provide a form locking connection in the peripheral direction. As a result of the peripherally fixed attachment of the annular part to the disk spring, wear caused by a relative twist between the annular part and the disk spring is prevented. | 08-13-2009 |
20160053849 | INTERLOCK SYSTEM FOR RING GEAR ON FLYWHEELS - A flywheel assembly for a prime mover includes a flywheel and a ring gear. The flywheel has a first plurality of apertures for receiving a first plurality of fasteners for fixing the flywheel to a prime mover, a first cylindrical ring portion including a first outer diameter, a second cylindrical ring portion at a first distal end of the first cylindrical ring portion and including a second outer diameter, larger than the first outer diameter, and a third cylindrical ring portion at a second distal end of the first cylindrical ring portion, opposite the first distal end, and including a third outer diameter, larger than the second outer diameter. The flywheel also has a first wall connecting the first distal end of the first cylindrical ring and a third distal end of the second cylindrical ring portion. The ring gear is engaged with the first cylindrical ring portion. | 02-25-2016 |
