Granted: 1980-06-24
Abstract: ABSTRACT OF THE DISCLOSURE     The present invention relates to measuring techniques intended to determine the operational characteristics of a road pavement by assessing the braking conditions of trans-port vehicles. The device comprises a single-axle trailer whose frame is coupled by a tow pole to a towing vehicle. The trailer has only two wheels adapted for rotating on the moving trailer with longitudinal slipping in opposite di-rections. The device also comprises a recording instrument with a sensitive element which is located between the trail-er frame and the free end of the pole and is kinematically linked therewith in such a manner that on the moving trailer the sensitive element is acted upon by a force which is pro-portional in magnitude to the sum of absolute values of the longitudinal traction forces acting on the wheels and is directed essentially parallel to said forces. Such a device will allow measuring the coefficient of adhesion with a ma-ximum possible accuracy as compared with the prior art de-vices; in addition, it is quite simple in design and opera-tion which ensures its successful and efficient employment on airfields.

Abstract: ABSTRACT OF THE DISCLOSURE   In a subsurface formation, where shaliness affects the results of typical electrical well logging measurements, partial water and partial hydrocarbon saturations are determined from measurements of dielectric constant.   A relation defining dielectric constant change as a function of partial water saturation is used to determine the partial water saturation and partial hydrocarbon saturation.  The relation between dielectric constant and conductivity due to shaliness in a partially water saturated formation is also used to determine partial water saturation and partial hydrocarbon saturation of said formation.  The value of "shaliness exponent" for the formation is determined from measurements of dielectric constant as well.

Abstract: ABSTRACT OF THE DISCLOSURE         The valve comprises a body which can be connected on two opposite sides to two pipes having the same axis, a rotary member inside the body is rotatable around an axis perpendicular to the common axis of the pipes. A port traverses the rotary member and in open position the port is of substantially the same axis as the pipes. Fluid-tight linings ensure the sealing of the valve in closed position.  The rotary member carries at least one cap movable in a direction perpendicular to the axis of rotation to ensure fluid-tightness in closed position,  An intermediate part is placed between the rotary member of the cap and is movable with respect to the rotary member between a resting position and an active position in which it exerts a force on the cap tending to separate it from the rotary member.  The body has a stop which does not limit the rotation of the rotary member whilst limiting that of one at least of the parts driven by the rotary member.  It modifies the relative position of the cap and the intermediate part by means of a cam surface through which the parts are in contact, the intermediate part being positioned to come into contact with the stop in the course of the movement of the rotary member.  The valve is particularly sure and of long life-span which is of particular value in the handling of corrosive and/or dangerous gases or liquids.

Abstract: ABSTRACT   There is disclosed a system for removing both anions and cations from solution.  A pair of endless belts are employed, one belt has incorpor-ated into its construction an anion exchange resin and the other belt has so incorporated a cation exchange resin.  Both belts are passed through the flowing solute in a direction opposite to its flow while simultaneously making a number of traversals perpendicular to the fluid flow.  All the fluid is caused to pass through each belt a plurality of times.  The fluid is there-by substantially deionized.  Upon leaving the flowing liquid, the anion belt is passed through an anion resin regeneration tank where it is stripped of its captured anions and regenerated prior to returning to the fluid under treatment.  The cation belt similarly is removed from the fluid under treat-ment and passes to a cation resin regenerating tank where it is similarly stripped of captured cations and regenerated prior to return to the fluid.
