Title: Apparatus for regenerating waste water
Inventor: NAKAJIMA MINEO
IPC: C02F1/52
Filed: 1982-04-22
Abstract: PURPOSE:To improve the separation of oil and sludge from each other, by a method wherein a flooding weir is provided to the inflow side of a separation chamber and a precipitation basin lower than the bottom surface of a treating tank is provided before a lower buffle plate to reduce a flow speed and to permit a precipitate to hardly receive the influence of flowing water. CONSTITUTION:Waste water flowed into the flooding weir of a first separation chamber 7 from an inflow pipe 30 through an inflow port 9 is slowely flooded over the total length in the width direction of the separation chamber 7 from a flooding port 10 to be supplied without agitating water in the separation chamber 7 and oil floated to the surface of water is dammed up by an upper baffle plate 3 while waste water containing mud is flowed through a flow passage 2 provided under the upper baffle plate 3 while subsequently impinged onto a lower baffle plate 5 protruded from the bottom surface of the separation chamber 7 and mud in water is precipitated and separated to a precipitation basin before the lower baffle plate 5. Waste water is flowed through a flowline 4 above the upper baffle plate 5 while residual oil floated to the surface of water is collected by the second baffle plate 3. Similar operation is repeated in the separation chamber 7 in a succeeding stage.

Title: Production of laminated tubular body and tube for coating
Inventor: KAWASAKI MINORU
IPC: F16L11/04
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To form a resin layer of a uniform thickness by one time of coating work on the inner peripheral surface of a tubular body having bent parts. SOLUTION: At the time of inserting a tube 30 for coating into the tubular body 11 from its one end side, a protective film member 33 has flexibility in a diametral direction and has rigidity in an axial direction and, therefore, this protective member moves smoothly to the position near the other end while the member is deformed along the tubular body 11 without kinking by the insertion resistance by coming into contact with the tubular body 11. An inside pipe is deformed as well according to the deformation of the protective member and does not, therefore, kink. While a resin coating material is ejected out of the blow-off port of a guide member 32 and while the tube for coating is gradually drawn from the tubular body, the coating is executed.  The blow-off port is arranged coaxially around the approximate axial line position of the tubular body and, therefore, the blown-off resin is deposited uniformly on the inside wall of the tubular body and the formation of the coating film of the uniform thickness free from the discrimination of the straight part and the bent part is made possible.
