Inventor: FROHN GUENTER
IPC: B24B5/48
Filed: 1987-01-17
Granted: 1988-09-01
Abstract: There is provided a method and apparatus for inside surface finishing with a high degree of dimensional accuracy and axial parallelism for long bores of very small diameter in work pieces. The method employs a high tensile strength steel wire as the grinding tool rotating at high speed under tension just below its yield strength. The wire is reciprocally moved back and forth in an axial direction and is coated with abrasive material. The work piece with the wire passing through its bore to be surface finished, is rotated eccentrically with respect to the wire and is axially parallel thereto. The inner wall of the bore is pressed against the wire which passes therethrough. The apparatus includes two clamping devices which reciprocally move back and forth together with a common base plate and which are rotated by synchronized drives. Between the two clamping devices the wire is stressed under tension, and a work piece holder which can be moved in a vertical direction transverse to the wire rotates the work piece.

Title: Output regulating valve fittable to suction apertures of mechanical ventilation system
Inventor: HASPEL BRAM VAN DEN
IPC: F24F11/75
Filed: 1997-04-17
Granted: 1998-10-20
Abstract: The valve (2) is located in a housing (1) and is rotatable around an axis (3) through or near its centre of gravity. The air through passage aperture of the valve is determined by the position of the valve in the housing. The valve is partially screened from the longitudinally flowing air. On the valve, as the result of the pressure drop over it and dependent upon its position, a torque is effective. When a specific pressure drop over the valve is exceeded, the valve is rotated in the most closed state. The angle of the valve is limited by means of two adjustable cams fixed to the valve housing. A spring provides the force with which the valve, with reducing pressure drop rotates openly in the most opened state (4). The sensitivity of the valve is adjusted by the position of the weight fixed to it (6).
