Abstract: A cue having a hollow cylindrical handle and a hollow cylindrical shaft with a constant external diameter. A tip member fixed to one end of the shaft and a connector fixed to the other end of the shaft. A butt member fixed to one end of the handle and a connecting member fixed to the other end of the shaft to connect the handle to the shaft. An adjustable weight is located in the hollow handle and a bridge sleeve surrounds the shaft. The bridge sleeve has a bushing at each end with an inner diameter slightly greater than the outer diameter of the shaft so that the shaft can slide through the bridge sleeve to cause a steady movement of the cue.

Abstract: A filter including a flexible mesh having feathers secured thereto is disclosed for separating out oil from an oily liquid. The feathers sorb the oil. In a first embodiment of the filter the feathers are adhesively secured to the mesh. In a second embodiment of the filter, portions of a fibrous polyester layer extend through the feathers and the mesh to secure the feathers to the mesh in fixed positions. A filter assembly, including a plurality of filters supported by a movable conveyor in spaced relationship, is also disclosed.

Abstract: An image acquisition system including at least two image projectors, a television camera and a modular desk for supporting the projectors and the camera wherein the image projectors are supported at predetermined locations on a tabletop supported for sliding and rotary movement so that the camera can receive projected images from a desired one of the image projectors by merely adjusting the angular position between the tabletop and a lower cabinet of the desk. The desk includes an upper cabinet having an image acquisition aperture formed therethrough and aligned with the desired one of the image projectors. The modular desk also includes a slab supported on the lower cabinet. In one embodiment of the invention a movable table supports the tabletop. In a second embodiment the tabletop is slidably and rotatably supported on a pair of spaced tracks mounted on the top surface of the slab.

Abstract: A filter including a flexible plastic mesh having feathers adhesively attached thereto on opposite sides thereof is disclosed for separating out oil from an oily liquid. The filter comprises an oil sorption element of a filtering device which houses the filter. A filtering system comprises a plurality of interconnected filtering devices which may be arranged in parallel or in series with each other. Control valves are provided for controlling the flow of the oily liquid to the filtering devices. A filter assembly, including a plurality of filters supported by a movable conveyor in spaced relationship, is also disclosed.
