Patent DE-3625144-C1 (DE)
Title: Device for transmitting a pressurised fluid
Inventor: BARTHELT KLAUS
IPC: B23Q1/00
Filed: 1986-07-25
Granted: 1987-07-02
Abstract: A device for transmitting a pressurised fluid comprises an outer part, in the opening of which with its rotationally symmetrical inner wall is arranged an inner part with a rotationally symmetrical outer wall. The two walls together delimit an annular gap which is closed in the axial direction by sealing means arranged a distance apart. Opening into the annular chamber formed in this way are flow passages formed in the inner and outer parts. In order to obtain a low torque even when the pressures to be transmitted are high and the sealing is good, this torque being required to adjust the two parts relative to one another, each of the sealing means has two flat annular sealing surfaces concentric with the axis which, in the case of each sealing means, lie axially opposite one another and extend radially to the axis. One of the two sealing surfaces of each pair of sealing surfaces is formed by an end face of an annular piston which is guided in a longitudinally displaceable fashion and in a sealed manner on that surface which does not carry the two axially outer sealing surfaces.

Title: Retaining lock for pressurised aircraft -  has slidable lock sections held by axial locking pins and shear pins
IPC: B64C1/18
Filed: 1991-02-01
Granted: 1992-03-12
Abstract: The retaining-lock (3) consists of two sections (4, 5), one connected to a decompression blow-out panel (2), and the other to the separating bulkhead or floor (6). The sections can slide apart, but are held together by axial locking-pins (7, 8), and internal, radially mounted, weak-necked shear-pins (9, 10). A large pressure differential, such as experienced in an explosive decompression, shears one pin-head (9a, 10a) in each lock (3), and releases the safety-panel.

Abstract: A pneumatic spring has elastomeric pneumatic-spring bellows which are tightly fastened at both its ends to one component each while forming a closed spring volume to which pressure can be admitted. One component has an additional volume interacting with the spring volume. In order to dampen the vertical oscillations of a pneumatic-spring system without restricting the displacement of the pneumatic-spring bellows in the process, the additional volume (29, 31) is separated from the spring volume (11) by a rubber diaphragm (26). The additional volume has a hydraulic pressure chamber (29) adjacent to the spring volume (11) and an air chamber (31) adjoining the hydraulic pressure chamber (29). The hydraulic pressure chamber (29) is subdivided in the vertical spring direction by a fixed wall (32) having a choke opening (33). The hydraulic pressure chamber (29) and the air chamber (31) are separated from one another by a second flexible rubber diaphragm (28). The air chamber (31) is in pressure connection with the pneumatic-spring volume (11). <IMAGE>

IPC: G01B21/24
Filed: 1990-09-13
Granted: 1995-02-09
Abstract: FIELD: measurement technology. SUBSTANCE: connecting tip with fiber is fixed for rotation about its own axis. Free end of fiber is illuminated by light source. Electron unit measures coordinates which are used for judging value of shift of center of light spot relatively center of revolution. Edge of mirror shutter is set into position at which it passes through center of revolution of basic surface of the tip. Light flux being reflected from mirror shutter is measured at four mutual perpendicular positions of optical fiber. In order to coincide edge of mirror shutter with center of revolution of basic surface of connecting tip, the edge of mirror shutter is shifted relatively end of tested optical fiber at first and connecting tip. Intensity of radiation reflected from mirror shutter is measured and then the shutter is set into position at which intensity of reflected light flux is equal to half sum of minimal and maximal intensities. In this case angular position of the optical fiber with connecting tip is defined by rotation about its axis at that position of the shutter at which intensity of light radiation reflected from mirror shutter is minimal or maximal. After that connecting tip is set at one of these positions and optical fiber is rotated to 90 deg. Values of minimal and maximal intensities are measured repeatedly by means of shifting mirror shutter relatively end of optical fiber and connecting tip. Then edge of mirror shutter is set into the position which corresponds to half sum of values of intensities achieved. After edge of mirror shutter is coincided with center of revolution of basic surface of connecting tip, the constant component is compensated and maximal amplification is introduced. Measuring circuit is calibrated for dial of shifter which determined portions of microns. Then edge of mirror shutter is coincided again with center of revolution of basic surface of connecting tip. Measurements are conducted and values measured are used for determining misalignment and angular shift of the line, which connects center of revolution of basic surface of connecting tip and center of light radiation. EFFECT: improved precision of measurement. 3 cl, 1 dwg
