    • 1,111,859. Measuring optically. A. FORTIER and J. L. PEUPE. Oct. 15, 1965 [Oct. 29, 1964], No. 43889/65. Heading G1M. [Also in Division G2] Apparatus for gauging the position of a movable object, for example a liquid level in a transparent tube, comprises means for projecting light on to a reflective curved surface movable bodily with the object, whereby the reflected light will envelop a caustic and form interference fringes adjacent said caustic, and a magnifying optical viewer for observing a selected one of said fringes. As shown, the viewer 7 and a light-source 15 are fixed on a rigid frame 16 which is displaceable parallel to a tube 2 containing a liquid 1, the level of which is under observation. Reflection of light from the source 18 at the curved meniscus 5 of the liquid sets up interference fringes which are observed through the viewer. A reticle wire in the viewer is brought into coincidence with a selected fringe by moving the viewer parallel to the tube 2. A comparator 11 supported on a fixed structure 3 which also mounts the tube 2 is coupled to the viewer 7 and adjusted to zero. Any subsequent variation in the liquid is recorded on the comparator 11 by moving the viewer until the same fringe coincides with the reticle wire. When an opaque liquid is under investigation the light-source 18 is arranged above the meniscus 5. In a further embodiment the light-source may be fixedly aligned with the tube 2 so that light strikes the meniscus in the same way regardless of the liquid level. In applying the apparatus to the measuring of displacement of a solid object a light weight element having a curved reflective surface, e. g. a glass rod, is attached to the object if such a surface is not provided by the object itself.

    • 1,066,354. Interferometric pressure gauge. J. -L. PEUBE. July 8, 1964 [July 8, 1963], No.28179/64. Heading G2J. The differential pressure between two sources is determined by connecting them to tubes e, f, so as to influence the level of the free surface of a liquid m in container a and forming interference fringes between the free surface and a flat strip I supported in the container a As shown light from source g is reflected at h and fringes formed between the reflecting surface of mercury m and transparent strip l are observed at v. A transparent silicone oil i provides damping of the mercury surface. In a modification, Fig.2 (not shown), the liquid employed is a transparent silicone oil and container (a) is filled to a level somewhat above the upper surface of plate (I) which is then formed with a reflective upper surface for forming the fringes. The viewer v may be replaced by a camera or photo-electric counter.

    • The invention relates to a device for eliminating sudden changes of pressure in a ventilated or air-conditioned vehicle, the device comprising: a detector for detecting changes in the pressure outside the vehicle and delivering signals representative of said changes; closure means for closing an outside air suction duct and an inside air rejection duct; a control unit receiving the signals from the detector and controlling closure of the ducts above a first determined rate of change in outside pressure, said unit also controlling re-opening of the ducts after said change in outside pressure has fallen below a second determined rate; and means for balancing the inside pressure and the outside pressure by a controlled flow of air between the outside and the inside of the vehicle, said means constraining the pressure inside the vehicle to change as a function of time at less than a set rate.
