Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for determining condition and homogeneity of the structure of coal seams by which pulsed electromagnetic energy is transmitted into the face of a coal seam, the energy transmitted into the face is received to develop a return signal per transmitted pulse, selected successive return signals are processed to eliminate source coherent interference while increasing the signal to noise ratio and any structural inhomogeneities within the coal seam are indicated visually.          Previous attempts have been made to use radar to explore geologic materials, but most of this work has been unsuccessful except when used in salt or extremely dry formations.  Thus, reliable indication has been produced only at very short depths of penetration of the signal, in the order of a few feet.  The present invention provides a ground probing radar for surveillance of ground formations, and in particular coal seams, which has relatively long effective range and yet has signal processing capability for materially reducing source coherent interference.

Abstract: TITLE OF THE INVENTION            TORQUE TRANSMITTING BODY FOR TRACTION DRIVE TRANSMISSIONS AND NORMAL FRICTION         FORCE DEVELOPING METHOD                 ABSTRACT OF THE DISCLOSURE         A torque transmitting body for continuously variable power transmissions of the type in which oppositely convergent, cone-like rolling surfaces of revolution about one axis are retained in torque transmitting rolling frictional engagement at two points of contact with complementing rolling surfaces of revolution about another axis inclined with respect to and intersecting the axis of the cone-like surfaces.  The body includes a pair of oppositely convergent cone members telescopically interconnected at their base or large ends for relative rotary and axial movement.  A cam assembly is included and acts between the cone members to develop an axial separating force in response to a torque differential between the cone members.  Although both cone members are driven at equal speeds, only one is connected to an output torque load so that the torque differential caused by the load may be converted to an axial separating force on the cone members by the camming assembly.

Abstract: L'invention a pour objet un perfectionnement à un procédé de valorisation de la coupe C4 en provenance d'une unité de craquage ou de craquage à la vapeur. Ce perfectionnement consiste à soumettre la coupe C4 oléfinique non pas à une simple réaction de polymérisation, mais à un couplage d'une réaction de polymérisation et d'une réaction d'isomérisation, couplage qui consiste non seulement à obtenir une transformation sélective de l'isobutène en dimères C8 et en trimères C12, mais également à provoquer le déplacement de la double liaison du butène-1 avec donc transformation de la majeure partie du butène-1 en butènes-2, pour atteindre, sous les conditions opératoires et avec les catalyseurs choisis, une composition assez proche de celle qui correspond à l'équilibre thermodynamique. Les autres constituants de la charge ne sont sensiblement pas transformés au cours de la réaction d'isomérisation. Cette transformation du butène-1 en butènes-2 présente un intérêt primordial pour la réaction d'alkylation effectuée après le fractionnement de l'effluent d'isomérisation, car les produits obtenus par alkylation des butènes-2 possèdent un indice d'octane nettement supérieur à celui des alkylats issus du butène-1.

Abstract: ABSTRACT OF THE DISCLOSURE       A switch point guard for railroad track having a guard or deflector rail positioned to prevent flanges of railroad wheels from striking the switch point.  The guard rail is carried on support members for rigid retention in a fixed, predetermined position relative to the track.  By this invention the guard rail is carried by horizontally positioned guard rail plates attached to the side of the guard rail.  Apertures are defined in the rail plates with chock plates positioned in the apertures.  The chock plates each define an aperture off center in the direction perpendicular to the guard rail, with the support members defining attached projecting members occupying the off-center apertures.  Accordingly, peripheral edges of the chock plates occupy different positions depending upon which side of the chock plates faces toward the rail track.          Thus the predetermined position of the guard rail can be varied.
