  • Patent number: 8973300
    Abstract: An insect trap for use in trapping and exterminating crawling insects including bed bugs. The trap includes a pit fall trap assembly with sidewalls defining a pit or well and a heat source positioned within the pit. The trap includes a controller assembly with a controller selectively operating the heat source, which includes a base plate provided at a bottom of the pit. In this way, the base plate provides the floor or lower surfaces of the pit upon which insects fall and also to which the insects are attracted by the thermal lure of the heat source. The inner surfaces preferably include a layer of anti-traction material (such as UHMW tape or the like) such that the insects cannot climb back out of the pit. The controller operates to alternate the heat source between a lure temperature mimicking a blood host and a higher temperature to exterminate trapped insects.

  • Publication number: 20110265679
    Abstract: An anti-roll back (ARB) assembly for use with vehicles that ride on a track, which has inclined portions that include a set of ARB or lift pins. The assembly includes a linear magnet assembly positioned along the track in the ARB portion, and this assembly includes spaced apart magnet arrays that define a slot or elongated magnetic force zone. The ARB assembly includes an ARB element with a body pivotally supported on a vehicle frame and further includes an electrically conductive reaction plate supported on the vehicle frame, and the plate passes through the magnet assembly slot when the vehicle travels on the track. The reaction plate is connected to the ARB body to pivot it in response to displacement of the reaction plate in response to magnetic forces to rotate it up into a suspended position in which the ARB body is spaced apart from the ARB pins.
