Patent CA-2154566-A1 (CA)
Inventor: SCHIWEK HELMUT
IPC: B65D85/84
Filed: 1994-01-07
Abstract: A safety container 1, whether as a tank trailer 3, oil tanker 41, a container 7 with hazardous material 202 or aircraft 301 can accommodate large amounts of hazardous material, above all, in liquid form as fuel, and transport it almost without endangering the environment, because the interior 10 of the container is filled with glass wool 12 in such a way that the stored hazardous material 202 or other filling cannot leak or in any other way reach the environment. The liquid components, e.g. hydrocarbons, are absorbed and held by the tightly sealed lattice 15 which has been made hydrophobic, so that oxygen cannot reach these materials. Thus, they are protected from explosions and leakage into the environment. At the same time, in oil tankers 41 and aircraft 301, a safety container 1 of this type assumes the function of a type of life preserver, since water cannot penetrate into the interior 10 of the container and any kerosene or gasoline or oil which is still present additionally promotes lift. Seen on the whole, it is noted that this simplifies the construction of the safety container and considerably improves safety.

Abstract: A video encoder control system and method are disclosed for controlling a video encoder using a processor having a multiple field delay circuit for delaying input video data by a predetermined number of frames, and a statistics generator for generating statistics from the video data to control the encoder. The statistics generator calculates a sum of absolute values of field differences between pixels, with the sum used for detecting a redundant field, for generating a film flag, and for controlling the encoder using the film flag. The statistics generator calculates averages of blocks of pixels, and a fade detector uses the averages for detecting fades between successive frames to generate a fade flag to control the encoding. The rate controller responds to the statistics to change the resolution of the encoding of successive frames. The processor outputs the film flags, scene change flags, and fade flags to the rate controller to control the encoding of the delayed video data. A method is disclosed for controlling the video encoder including the steps of delaying the input video data, generating frame statistics, and controlling the encoder using the statistics.

Abstract: A lubricant distribution system for a vehicle transmission includes an internal fluid pump which draws lubricant from a sump defined in the transmission housing through an intake tube and a first channel formed in an interior wall of the housing. The lubricant is delivered from the pump through asecond channel formed in the interior wall to a first port formed in an outer wall of the housing. A third channel is also formed in the interior wall, extending from a second port formed in the outer wall to an internal passageway formed within the interior wall. The ports may be used to circulate lubricant from the transmission to one or more external devices for conditioning the lubricant. Alternatively, a cover plate secured to the housing may provide direct communication between the two ports. A bypass channel may be formed in the interior wall between the second channel and the third channel. A pressure relief valve disposed in the bypass channel prevents fluid flow therethrough unless thepressure of the lubricant in the second channel exceeds a predetermined value. The various channels are all formed having generally U-shaped cross sections and are closed by a cover plate to define respective fluid passageways. The lubricant passes from the internal passageway to a lubricant discharge tube supported in a bore formed through the interior wall. The lubricant discharge tube includes one or more resilient outwardly extending tabs which provide a bayonet type mounting thereof in the bore. The lubricant discharge tube includes first and second legs having respective pluralities of apertures formedtherein. Lubricant sprayed from the apertures falls from the meshing gears and bearings under the influence of gravity and is collected in the sump.
