Abstract: Greasable idler pulleys and related kits and methods are disclosed. The greasable idler pulley has a rotating body, a bearing, to enable the rotating body to rotate with respect to a shaft, and grease fitting defined through the rotating body. The rotating body may have a bearing seal cap having an orifice and a rotator. The grease fitting may be in fluid communication with the bearing through the orifice in the bearing seal cap. Kits are also contemplated, such as a kit for retrofitting a non-regreasable idler pulley including a rotator to a regreasable idler pulley. Methods may include methods of producing a regreasable idler pulley from a non-regreasable idler pulley.

Abstract: A fluid coupling device and coupling system that may start and stop the flow of a fluid is disclosed. In some embodiments, first and second couplings are provided having an actuator coupled with each of the couplings. The couplings and actuators may be detachable to provide quick disconnect features and, in some embodiments, provide unitary actuation for the actuators of the coupling device to facilitate connection in mobile applications. Actuation may occur as the two couplings and actuators are engaged and disengaged and may occur by rotational actuation of the actuators. Rotational actuation can be provided to ensure flow through the coupling device, which in some embodiments may further provide an offset venturi feature. Upon disengagement, a compression element such as a compression spring can be provided to return the actuators to a closed position. Some embodiments further provide a seal external to the actuators and provided at incipient engagement of the couplings.

Abstract: An all purpose surface support station for use in dive applications having an inflatable bladder for floating the station, a screw-in type anchor for docking the station, removable pockets for storing dive equipment, and a cover that can store dive equipment, protect the bladder and, upon deflation of the bladder, is also used as a device for transporting dive equipment to and from the dive site.

Abstract: A novel security lock for laptop and notebook computers which prohibits the separation of the monitor from the keyboard, may provide an audible motion sensitive alarm and a secondary anchor cable.

Abstract: A sound mixer processor and related system and methods employs an fiber optic line; optical interfacing means; and, in some embodiments, logic circuitry to contol and monitor multiple input and output allocations.

Abstract: A glare shield adapted to be positioned within the passenger compartment of a motor vehicle adjacent to the windshield to absorb and intercept light rays in which the glare shield is made up of flexible material forming compartments containing ballast material acting as a base to support a relatively flexible shield member which may be deflected to various positions relative to the base member.
