Abstract: Illuminating fans for loading docks are disclosed. An example illuminating fan includes a housing defining an airflow chamber and an electrical chamber divided by an internal wall of the housing. The illuminating fan also includes a fan wheel mounted for rotation within the airflow chamber. The fan wheel is driven by a fan motor to generate a current of air passing through the airflow chamber. The illuminating fan further includes a lamp supported by the housing. The lamp is wired to an electrical circuit at least partially contained within the electrical chamber.

Abstract: Dynamically configurable traffic controllers and methods of using the same are disclosed. An example apparatus includes a first sensor to face a first direction to detect oncoming traffic in a first area, a second sensor to face a second direction to detect oncoming traffic in a second area, and a first display to face the first area. The first display is to display a first signal in response to (1) the first sensor not detecting the oncoming traffic in the first area and (2) the second sensor detecting the oncoming traffic in the second area. The first display is to display a second signal in response to (1) the first sensor detecting the oncoming traffic in the first area and (2) the second sensor detecting the oncoming traffic in the second area. The first signal is different than the second signal.

Abstract: Dynamically configurable traffic controllers and methods of using the same are disclosed. An example apparatus includes a first display facing a first direction; a second display facing a second direction; a third display facing a third direction; and a processor, in response to a first input being received indicative of traffic approaching the first display and no traffic approaching the second display and the third display, the processor to cause the second display and the third display to display a first signal and for the first display not to display the first signal or a second signal, the first signal providing a first warning level, the second signal providing a second warning level greater than the first warning level, the first signal illuminatable on the second display, the second signal illuminatable on the second display, the first signal, when illuminated, disposed within a perimeter of the second signal, when illuminated.

Abstract: A retractable bollard system for installation in a support surface that includes pavement includes a shell that when installed in the support surface extends below an upper surface of the pavement. The bollard system includes a post to be telescopically coupled to the shell. The post is axially movable relative to the shell selectively to an upper area and a lower area. The post extends farther above the shell when the post is in the upper area than when the post is in the lower area. The bollard system further includes a shock absorber to encircle the shell. The shock absorber is made of a polymeric material.

Abstract: An example bollard system includes a post extension to extend upward from a floor, and a first collar to encircle the post extension. The example bollard system includes a first connector to encircle the post extension adjacent to the first collar, and a first handrail to be connected to the first connector. The example bollard system includes a second connector to encircle the post extension adjacent to the first connector, and a second handrail to be connected to the second connector. The example bollard system includes a second collar to encircle the post extension adjacent to the second connector. The first collar is invertible selectively to a first lock position and a first release position, the first connector having greater freedom to rotate relative to the first collar when the first collar is in the first release position than when the first collar is in the first lock position.

Abstract: In an aspect, the invention relates to compositions and methods production of n-butanol by aerobic hydrogen bacteria. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

Abstract: Powered safety curtains are disclosed herein. An example barrier includes a motorized drive unit, and a curtain. The curtain includes a leading edge. The leading edge of the curtain is selectively moveable to a closed position and to an open position. The example barrier also includes a guide plate carried by the curtain and extending into a track and a nonferrous guide member attached to the guide plate. The example barrier also includes a first safety device including a first wireless portion and a first electrical portion. The first wireless portion is attached to the nonferrous guide member. The first electrical portion is in a first activated state when the first wireless portion is in proximity with the first electrical portion. The first wireless portion is in a first deactivated state when the first wireless portion is remote relative to the first electrical portion.

Abstract: Powered safety curtains are disclosed herein. An example safety barrier assembly to control access to equipment includes a track and a barrier including a receptacle. The barrier is to be moveable within the track between an open position and a closed position. The open position is to enable access to the equipment, the closed position to substantially prevent access to the equipment. The example safety barrier assembly also includes a sensor to identify when the safety barrier is in the closed position and a securing device comprising a portion to be received by the receptacle when the barrier is identified as being in the closed position. An interaction between the portion and the receptacle is to prevent the barrier from moving out of the closed position.

Abstract: An article of jewelry with interchangeable settings and decorative elements is provided. Each interchangeable setting includes a post having a post shoulder and a pair of tabs. The post is removable received and retained by a socket of the article of jewelry by inserting the post into the socket and rotating the setting to position the tabs in a retained position within a pair of corresponding grooves formed in the socket. An end of the socket abuts the post shoulder and prevents the interchangeable setting from side-to-side movement. Decorative elements are rotatably retained by the post between the setting and the socket.
