Abstract: A site light including a body, an arm coupled to the body having an adjustable arm length, a light assembly coupled to the arm opposite the body, and a drive assembly configured to alter the arm length. The drive assembly, in turn, includes a drive wheel mounted for rotation with respect to the body, an idle wheel mounted for rotation with respect to the body, and a biasing member configured to bias the idle wheel toward the drive wheel. The site light also includes a cable coupled to the arm where the cable is positioned between and engaged by both the drive wheel and the idle wheel.

Abstract: A wireless hoist system including a first hoist device having a first motor and a first wireless transceiver and a second hoist device having a second motor and a second wireless transceiver. The wireless hoist system includes a controller in wireless communication with the first wireless transceiver and the second wireless. The controller is configured to receive a user input and determine a first operation parameter and a second operation parameter based on the user input. The controller is also configured to provide, wirelessly, a first control signal indicative of the first operation parameter to the first hoist device and provide, wirelessly, a second control signal indicative of the second operation parameter to the second hoist device. The first hoist device operates based on the first control signal and the second hoist device operates based on the second control signal.

Abstract: A fluidized bed apparatus for treating particulate material comprising a foraminous support such as a perforate plate, a screen, or the like, gas supply means to supply a fluidizing gas beneath said support and a plurality of movable flights above said support adapted to sweep fluidized material along the support. The apparatus is useful for obtaining controlled residence time of materials being treated within an enclosed treating chamber.

Abstract: The present invention relates to gas treating apparatus for treating web-like or granular material conveyed through the apparatus, and more particularly to a novel nozzle arrangement for such apparatus which insures that a uniform, unbroken stream of treating medium impinges against the web-like or granular material. The present invention is particularly applicable to the transverse orientation of polymer film, the drying of particulate material, the drying or heat setting of films or fabrics, and other such applications where precise control of processing conditions is required.
