20090314588 | ELECTROMAGNET AND ELEVATOR DOOR COUPLER - An electromagnetic coupling device includes a vane member and an electromagnet. The electromagnet includes a core having a plurality of poles comprising at least four poles. An electrically conductive winding has a first portion surrounding a first one of the poles and a second portion surrounding a second one of the poles. The winding is selectively energized for selectively magnetically coupling the electromagnet and the vane member such that the vane member and the electromagnet are movable together in a desired direction. | 12-24-2009 |
20100247397 | MAGNETIC COUPLING DEVICE FOR AN ELEVATOR SYSTEM - A catalyst-carrier supporting material of a catalytic converter excellent in heat resistance and capable of maintaining a sufficient holding capability for supporting the catalyst-carrier for a long duration even in the environments exceeding 950° C. The catalyst-carrier supporting material comprising: a heat resistant layer which contains crystalline alumina fibers and an organic binder evenly impregnated with the crystalline alumina fibers and to be eliminated by thermal decomposition; and a thermally intumescent layer layered on the heat resistant layer which contains crystalline alumina fibers, an organic binder dispersed in the crystalline alumina fibers and to be eliminated by thermal decomposition, and vermiculite dispersed in the crystalline alumina fibers, wherein the crystalline alumina fibers exist in an amount of 1,400 g/m2 or higher in the catalyst-carrier supporting material, the ratio of the amount of the crystalline alumina fibers existing in the heat resistant layer and the amount of the crystalline alumina fibers existing in the thermally intumescent layer is 0.98 to 1.98, and the vermiculite exists in an amount of 23 to 33% by weight in the thermally intumescent layer. | 09-30-2010 |

20120247919 | DETECTION OF PEOPLE RELATIVE TO A PASSENGER CONVEYOR WITH A CAPACITIVE SENSOR - A system for detecting a person relative to a passenger conveyor includes a driving circuit for supplying an oscillating drive signal to a first electrode of a capacitive sensor configured to produce an electric field toward a second electrode in response to the oscillating drive signal. A detection circuit is connected to the capacitive sensor, and produces an output as a function of the capacitance of the capacitive sensor, such that the detection circuit senses a change in capacitance of the capacitive sensor, such as when a person enters the electric field between the first and second electrodes. A controller is responsive to the change in capacitance sensed by the detection circuit to selectively adjust an operation mode of the passenger conveyor. | 10-04-2012 |

20130264075 | FIRE SUPPRESSION SYSTEM WITH VARIABLE DUAL USE OF GAS SOURCE - An exemplary fire suppression system includes a sprinkler nozzle. At least one conduit is connected to the nozzle for delivering a fire suppression fluid to the nozzle. The conduit and the nozzle establish a discharge path. A pneumatically driven pump is connected with the conduit for pumping fluid into the conduit. A gas source provides pressurized gas to the pump for driving the pump. The gas source also provides gas to the discharge path for achieving a desired discharge of the fluid from the nozzle. A controller selectively controls at least one of (i) the gas provided to the pump, which controls the fluid pressure in the conduit, or (ii) the gas provided to the nozzle or the conduit, which controls the gas pressure delivered to the nozzle. | 10-10-2013 |

20140138102 | EFFERVESCENT FIRE SUPPRESSION - An exemplary fire suppression system includes a nozzle body configured to carry a fire suppressing fluid to be discharged from a first orifice array and a second orifice array. Gas bubbles can be introduced through a bubbler into the fire suppressing fluid to establish a bubbly mixture in the nozzle. Each first orifice in the first orifice array has a first flow property and is configured to receive the bubbly mixture and through effervescent atomization yield a first fire suppression mist from the first orifice array. Each second orifice in the second orifice array has a second different flow property and is configured to receive the bubbly mixture and through effervescent atomization yield a second fire suppression mist from the second orifice array. The first fire suppression mist and the second fire suppression mist are configured to provide a selected fire suppression nozzle discharge. | 05-22-2014 |
