Abstract: A storage cabinet includes a housing having at least one exterior port, at least one interior port positioned above the exterior port, and a convection passageway connecting the exterior port and the interior port such that warm air will rise within the passageway by natural convection from the exterior port to the interior port. The cabinet also includes at least one drawer received within the housing and moveable between a closed position wherein a storage space within the drawer is inaccessible from outside the housing, and an open position wherein the drawer extends out of the housing such that the storage space is accessible. The drawer has at least one inlet for allowing airflow to pass from the interior port of the housing to the storage space of the drawer when the drawer is in the closed position. Another storage cabinet provided by the present disclosure includes a housing and at least one drawer received within the housing and moveable between a closed position and an open position.

Abstract: A video camera comprises a video camera body and a light module. Structure is provided, integral with the video camera body, for selectively positioning the light module. The light module can be removably connected to the video camera body.

Abstract: An interchangeable mount for a light housing or module adapted to be mounted on a video or film camera or other support surface includes interchangeable shafts, one of which is affixed to a thumbwheel rotatably mounted in the light housing. Should the camera be provided for the receipt of a threaded fastener to mount the light housing on the camera, the shaft received and fixed to the thumbwheel can have an integral, depending threaded connecting element received in the threaded bore in the camera to mount the housing, upon rotation of the thumbwheel. Should the camera be provided with a U-shaped clip in cross-section or "shoe" for mounting the light module, the shaft may include a threaded fastener or screw having an elongated head depending and threadably connected to the bottom of the shaft fixed to the thumbscrew.

Abstract: Two hemispherical ball components are joined to permit one to be rotated relative to the other. Each component not only defines the ball's spherical surface but also defines a "flat" minor spherical segment. By manually manipulating the flat on one component relative that on the other one can provide any number of trick throws or pitches to confuse a batter.

Abstract: A hollow plastic ball bat has an internally mounted swing metering device that provides a visual indication of swing velocity. The bat is defined by inner and outer members that are coupled to one another to define a recess that receives a transparent annular barrel. A bore in this barrel has a weighted piston that moves in the bore, as a result of its inertia, During a swinging or other movement of the bat itself.
