Abstract: The present invention relates to a corner connecting portion for a sealing gasket of a motor vehicle window glass, the gasket forming a window glass run channel of the hidden frame type. It is designed to connect a top segment to an ascending segment of the glass run channel, and it comprises: an upper part comprising an upper face designed to be sealingly mounted under the vehicle bodywork and a lower face designed to be mounted on said pillar by mounting means, and a lower part which is connected to the upper part by forming a “?” designed to surround an outer end of said pillar and which is designed to be sealingly in contact with the window glass. The mounting means comprise a pin which is inserted into a corresponding through hole formed in the upper part so as to extend from the upper face to the lower face, the pin being pushed through a pillar opening in an assembly position, to minimize the displacements of the gasket in response to ageing and fatigue cycles due to slams of the door.

Abstract: A process for measuring electric voltages and/or electric fields by the use of a crystal with an electro-optical (Pockels) effect. To this end, in a direction transverse to the direction of propagation (y direction) of a light wave polarized in the z direction, an electric field intensity gradient is generated in the crystal in the direction from which results a corresponding gradient in the refractive index n of the crystal. This produces a deflection of the light wave in the crystal which depends upon the field intensity and on emergence, it is used as a measure for the voltage of field intensity. A suitable sensor for this purpose is also described.

Abstract: In the case of a fiber optics arrangement for measuring the intensity of an electric current while utilizing the Faraday effect in which the magnetic field surrounding the conductor 1 through which the current flows affects the polarization condition of the light, the path of which leads through the core of an optical fiber 2 which surrounds the conductor 1 in the form of a coil, the light coupled out of the optical fiber 2, by means of a beam splitter 9, being divided into two partial light beams, the intensities (I.sub.1, I.sub.2), after passage through one polarizer 12, 11 respectively, being measured by one photodetector 14, 13 respectively, the object of expanding the measuring range of the arrangement is achieved by the fact that the polarizers 12, 11 are rotated symmetrically with respect to one another in comparison to the conventional angle of 45 degrees, the angle (.alpha.
