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 hair brush has a body with a head, a plurality of bristles carried by and protruding relative to the head, and a water absorbent material carried by part of the body and dispersed among at least some of the plurality of bristles.

Abstract: A process for the recovery of light mixed hydrocarbon vapors from an air-hydrocarbon mixture expelled as a result of storage breathing or loading of a vented hydrocarbon vessel. The hydrocarbon vapor components are adsorbed from the mixture, thus permitting venting of the substantially hydrocarbon free air safely to the atmosphere without pollution. The adsorbed hydrocarbons are removed by subjecting the adsorbent bed to a lower pressure, and the hydrocarbon components in the resulting desorption stream are substantially adsorbed for recovery, and the remaining gases from the absorption vessel are passed through a second adsorption bed to substantially remove any hydrocarbons therein.
