20140326581 | Counterbalanced Elevating Conveyor - An elevating conveyor is mounted to a pivoting bridge so that the elevating conveyor can be shifted by a 22 degree rotation between a lowered position in engagement with a loading floor and an elevated storage position where the conveyor is out of the way of the loading floor. A counterweight arrangement is mounted to the bridge to bias the conveyor toward the loading floor when it is in a lowered position, and to bias it toward the elevated storage position when it is in the up position. The conveyor may be readily moved between the positions with a moderate application of force. The force may be applied by an operator standing on the loading floor or by a liner actuator mounted between the bridge and a fixed structure. | 11-06-2014 |

20090050452 | SWITCHING DEVICE HAVING WELDING TABS FOR SECURING SENSING STRUCTURES TO THE DEVICE HOUSING - A switching device includes a housing having an exterior surface with at least one opening in the surface. An inner edge of the opening is for receiving and securing solid bodies. At least a portion of the inner edge of the opening includes an integral weld tab which is raised above a level of the exterior surface. A sensing body includes a sensing structure operable to sense at least one condition. The sensing body has an outer surface that is disposed partially within the housing and secured to the edge of the opening by the weld tab, wherein the weld tab provides weld material physically bonding the outer surface of the sensing body to the housing. | 02-26-2009 |

20090026055 | Sealed dual plunger switch assembly with simultaneity - A sealed dual plunger switch assembly includes two switch sub-assemblies comprising plunger actuating mechanisms and basic switches. The sub-assemblies can be inserted into an overall enclosure using shims in order to position their operate points in the desired range relative to the enclosure's mounting surface. The enclosure is then sealed using a combination of covers, gaskets, o-rings, connectors and potting. The sub-assemblies individually and/or simultaneously receive actuation inputs within a fixed distance from the assembly's mounting surface. | 01-29-2009 |
