Title: Composite hollow member having optimized material at each position and manufacture of the same
Inventor: OYABU HIDEO
IPC: B29C47/66
Filed: 1993-02-22
Abstract: PURPOSE:To provide a cylinder material having good properties in general especially resistace to breakage by forming lining materials in a layer structure in a state in which the materials are arranged in the radial and/or longitudinal direction, or arranged randomly. CONSTITUTION:Different kinds of lining allay powders 3, 4, 5 are packed in the inside of a hollow base material 2 to form a layer structure in a state in which they are arranged in the radial and/or longitudinal direction, or arranged randomly. The packed part, after being sealed and deaerated, is sintered to form a lining layer. When more than one kind of the lining alloy powder is packed in the inside of the hollow base material 2 to form a layer structure in the longitudinal direction, if there exists a large difference in the coefficient of linear expansion between the base material 2 and the lining material, a lining alloy powder with an intermediate coefficient of linear expansion is arranged between the two. In this way, a cylinder having good properties is obtained.

Title: Treating system of discharged water from desalting device
Inventor: FAN KEN HO
IPC: B01D17/02
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To treat a discharged water from a desalting device so as to reuse the water by adding an anionic flocculant to the water discharged from a reaction tank and retaining the water. SOLUTION: The oil content in a discharged water from a desalting device is removed by using a slop oil separator 1. Since the water from which the oil content is removed contains an oil content in an emulsion state or as suspended substances, these substances are removed in a WSR separator 2 by using naphtha. The water treated in the WSR separator 2 is heated in a water stripper 4 to remove the gas component. Before the water is treated in the water stripper 4, the water is made to pass through a buffer tank 3. The water treated in the water stripper 4 is reacted with activated carbon in a reaction tank 5. In this process, the water is preferably stirred by a stirrer or air supply device 15. The water treated in the reaction tank 5 is sent to a retention tank 6, where an anionic flocculant is added.  In the retention tank 6, the water is retained for about 5 min while divided into sludge and the treated water.
