Title: Cylinder curvature grinding apparatus
Inventor: SAKATA YUUICHI
IPC: B24B5/36
Filed: 1980-05-15
Abstract: PURPOSE: To grind the surface of a slate at a high efficiency by invariably bringing a grinding tool into contact therewith in the direction of normal line while keeping a distance between the surface of the slate and a rotating shaft thereof constant irrelevant to the curvature thereof.  
     CONSTITUTION: A retaining frame 40 supporting a slate S rotates about a horizontal rotating shaft 41 with a motor 53 and gears 51 and 52. A moving base 60 carrying these components thereon moves horizontally on a rail 61 with a motor 62 at the right angle to the rotating shaft 41. Gears 76 and 77 are mounted rotatively on a bracket 71 integral with the rotating shaft 41 and meshed with a gear 78 in which the rotation of the gear 77 is checked against a housing while three proximity switches are mounted on a shaft of the gear 76. The rotation of the retaining frame 40 and the horizontal movement of the moving base 60 are controlled based on the relative position of the bracket 71 to a profile gauge 90 detected by this whereby a grinding tool R is invariably brought into contact with the slate in the direction of normal line.

Abstract: PURPOSE:To prevent the rolling vibration in a vertical surface effectively, by providing a liquid tank in which a part of the liquid is stored, connecting the liquid tanks with a connecting pipe, and arranging a resistance member at a flow part of the liquid in the liquid tank or connecting pipe. CONSTITUTION:At the time of an earthquake, etc., for a liquid storage tank 1, a stored liquid 3 which is stored in a tank main body 2 causes sloshing, and a floating roof 5 rolls in the directions shown by the arrow C, D. Concerning some of respective vibration control damper equipments which are arranged on the floating roof 5, a difference in height in the directions shown by the arrow A, B is generated between liquid tanks 7 and 9. For example, if the liquid tank 7 becomes higher than the liquid tank 9, a liquid 8 in the liquid tank 7 flows into the lower liquid tank 9 on the opposite side through a communicating pipe 10. However, a resistance member 11 to obstruct the flow of the liquid 8 is arranged at a flow part of the liquid 8 in the communicating pipe 10 and the respective liquid tanks 7, 9, a phase shift occurs between the flow of the liquid 8, which has been generated between the liquid tanks 7, 9, and the oscillation cycle of sloshing of the stored liquid. As a result, the liquid 8 in the liquid tanks 7, 9 acts to suppress the rolling vibration of the floating roof 5 in the directions shown by the arrow C and D.

Abstract: PROBLEM TO BE SOLVED: To surely enlarge the diameter of a cylindrical braid and secure a flow passage by filling high-viscosity fluid from one end of the cylindrical braid, inserting a diameter enlarging pig from the back, and by carrying it to the other end. SOLUTION: In enlarging a cylindrical braid 2 drawn into such an attitude as being laid along the shape of a pipe P more than the insertion state, high- viscosity fluid L such as one-liquid type polyurethane resin solution is filled from one end of the cylindrical braid 2, a diameter enlarging pig 3 is inserted from the back, and the pig 3 is carried to the other end of the cylindrical braid 2 by pneumatic pressure. While the pig is carried in the cylindrical braid 2, the high-viscosity fluid L pushed by the pig 3 expands the front part of the pig 3 in the flat cylindrical braid 2. Then, the fluid L enlarges the cylindrical braid 2 while contracting it longitudinally and pulls the top part to the front side in the pipe P shaft center little by little so as to eliminate any catching in the pipe P, reduce the passing resistance of the pig 3 in the rear, and facilitate the passing.
