摘要： The present invention relates to devices that include a mechanochromatic material (10) which changes color according to a pressure exerted on the device. As a result, the mechanochromatic material (10) functions as an indicator of pressure exerted on the device. A user can view the mechanochromatic material (10) to determine whether the pressure exerted on the device exceeds a threshold pressure, whereat a color change will occur in the mechanochromatic material (10).

摘要： The present invention relates to an actuating device (12) with a pressure cell (1) for actuating mechanical systems by means of an actuating rod (13). To determine intermediate positions of the actuating rod (13) in a simple and inexpensive way, a housing (17) of the pressure cell (1) consists entirely or partially of a translucent plastic. Furthermore, a lug (4, 5) that is firmly connected to the actuating rod (13) is provided inside a chamber (14) of the pressure cell (1), with a light barrier (3, 6) arranged outside the pressure cell (1) to detect the position of the lug (4, 5).

摘要： A fiber optic pressure sensor includes an optical fiber for transmitting light. The optical fiber has an axis. The fiber optic pressure sensor also includes an etched diaphragm perpendicular to the axis. The diaphragm includes an operative side located at a distance from the optical fiber sufficient to reflect a portion of the transmitted light into the optical fiber. The etched diaphragm includes a semiconductor, a dielectric, and/or a metal.

摘要： A device for checking the functioning of a gas measuring apparatus which includes a tubular connection for the passage of a gas so that it can be directed through a tube mounted in the connection which has means therein such as a chemical for measuring the gas which is passing therethrough. The device comprises a translucent diffusing screen mounted on the tubular connection so as to be able to view through the screen and into the gas passage and a spring diaphragm connected to the tube having a side disposed in space relationship to the screen and viewable through the screen and gas between the screen and the diaphragm when the diaphragm is flexed in one direction in respect to the screen so as to position it closer to the screen. The diaphragm is also flexed by a pressure variation within the tube and on the exterior of the diaphragm, for example when the pressure conditions within the tube are not as to be expected for normal functioning so as to move the diaphragm in an opposite direction away from the screen and to render the diaphragm invisible when viewed through the screen and the gas. The diaphragm is advantageously made of a distinct color so that its appearance or disappearance from view is readily apparent.

摘要： Disclosed herein is a fluid pressure indicator for providing visual indication whether or not the magnitude of a fluid pressure condition is above a predetermined minimum value. The indicator comprises indicating means having an indicating portion and a diaphragm. The indicating means is movable between a first extreme position in which the indicating portion is not visible and a second extreme position in which the indicating portion is visible. The diaphragm has a fixed portion and a resiliently deformable portion which is affixed to the indicating means and movable responsive to changes in the magnitude of the fluid pressure condition. The indicating means is thus movable with the resiliently deformable portion, such that whenever the magnitude of the condition is not in excess of the minimum value, the resiliently deformable diaphragm portion holds the indicating means in its said first position, but a predetermined increase in the magnitude of the condition above the minimum value will deform the deformable diaphragm resiliently, thus to move the indicating means to its said second position.

摘要： An indicating instrument for vehicles incorporating a piston which is so arranged that a slight movement causes a much larger displacement of a liquid level in a liquid column which is visible through a transparent housing of the instrument. In one embodiment the piston is movable in response to intake manifold pressure of an engine to indicate the efficiency of fuel utilization and in another embodiment, the piston is movable in response to a pendulum to indicate that the vehicle is either accelerating or decelerating.
