Abstract: CUTTERBAR WEAR STRIP ABSTRACT OF THE INVENTION A wear strip for a reciprocating cutterbar on a crop harvesting machine is disclosed wherein the wear strip projects upwardly and forwardly from the cutterbar support bar to a position above the rear edge of the knives.  This wear strip operates to hold the rear edge of the knives downwardly against the support ridge on the knife guards.  This wear strip is also operable to prevent severed crop material from passing between the knife guard and the support bar of the cutterbar and, therefore, being lost from the harvesting machine.  The structural shape of the disclosed wear strip also helps retard the passage of severed crop material forwardly over the front of the cutterbar.

Abstract: Précis Lorsqu'une personne seule fait une promenade en canot par temps très venteux, il devient presque impossible de pouvoir le contrôler à moins d'être deux rameurs à bord. Dans la présente invention, il est possible dans les mêmes conditions pour un seul canotier, de le maîtriser à cause du système de pédalier installé dans le fond, qui, lorsque mû par le pédaleur donne le mouvement de rotation requis à une hélice à l'arrière, laquelle peut se déplacer de gauche à droite par une commande manuelle du pédaleur, entraînant ainsi le canot dans la direction voulue. Aussi le "canot pédalé" peut comporter deux systèmes de pédalier synchronisé permettant ainsi à deux canotiers d'atteindre une plus grande vitesse.

Abstract: ABSTRACT Heat is stored in a closed basin having a net inflow of relatively fresher water connected by a strait to a larger body of relatively saltier water by selectively controlling the exchange of water between the body and the basin as a function of the season of the year.   In   summer,  the exchange of water is promoted thereby permitting relatively warmer and saltier water outside the basin to flow through the strait into the depths of the basin.  In winter, the exchange of water between the basin and the body of water is suppressed thereby   trapping warm, relatively saltier water in the lower regions of the basin, the warm water being available during the winter and being protected against heat loss by a surface layer of relatively fresher water.  The heat thus stored can be utilized in various energy   conversion processes such as heat pumps to raise the temperature to useful levels.

Abstract: Title of the Invention SEISMIC EXPLORATION USING COMPRESSIONAL AND SHEAR WAVES SIMULTANEOUSLY Abstract of the Disclosure In a method of seismic exploration using swept-frequency signals, compressional and shear waves are emitted simultaneously.  Typically the waves are generated by swinging-weight vibrators acting through a single base-plate.  If the frequency of the shear vibration is one-half that of the compressional vibration, the downward vertical forces can be phased to minimize the horizontal slippage of the baseplate.  The sensitive axis of the geophones is inclined to the vertical for detecting both compressional waves and shear waves.  For defined ranges of sweep rate, separate compressional and shear records are obtained by cross-correlating the geophone signal separately against the vertical and horizontal emissions.
