Granted: 2007-10-02
Abstract: An articulable food container. The food container is articulable from and between a first open position to a second closed position. In the first open position the food container can receive food. Additionally, the user may eat from the food container while it is in the first open position. In the second closed position, the food container covers or encloses the food. The closed position is useful for storing the food, heating the food, transporting the food between the point of service and the point of consumption, and/or disposing of the remnants of the food once the meal is completed. The food container may take the form of a plate, bowl, tray, clam shell, or other known configurations.

Title: Method for the biological purification of waste waters and waste gases and biofilter therefor
Inventor: BUELNA GERARDO
IPC: C02F3/04
Filed: 1998-06-30
Granted: 2005-03-08
Abstract: Apparatus for the purification of waste water and/or waste gas using a biofilter containing a filtering material, wherein the waste water move downwardly thereinto while the waste gas move upwardly or downwardly thereinto, is disclosed. Also disclosed is an apparatus for simultaneous purification of waste water and waste gas, comprising a filtering material comprised of a succession of layers. In a preferred embodiment, the upper layer of filtering carrier material has a substantially lower filtration capacity than a lower layer of filtering carrier material, to prevent clogging of the filtering material upon downward flow of the waste water. A negative gradient of filtering capacity in the direction of flowing gas is also provided, for preventing adverse pressure drop of gas flowing through the filtering material. More conveniently, the apparatus comprises sufficient filtering material between the gas inlet and water outlet to ensure that the water coming out of the apparatus has not been substantially contamined by the upwardly moving waste gas. Filtering compositions for purification of waste water and waste gas are also disclosed. Finally, the invention relates to a method for the purification of various types of waste waters and/or waste gases.

Abstract: A connection system for connecting external devices to specified locations on a marine seismic streamer. Inner collars are clamped to the cable at specified locations along its length. Each inner collar forms a circular race encircling the cable.  A cuff attached to an external device is in the form of a C-shaped cylindrical ring with a circular inner surface. A throat is formed in the ring by a gap, which extends the full length of the cuff across the ends of the C. The spacing between the ends of the C across the throat defines the width of the gap, which is slightly larger than the diameter of the cable so that the cuff can be slipped over the cable through the throat, and which is smaller than the diameter of the circular race so that, when the cuff is slid into position on the race, the cuff cannot be removed radially.
