Abstract: ABSTRACT OF THE DISCLOSURE        A new chain harrow of improved performance with regard to effective harrowing and non-clogging is made up of V-shaped elements (as seen in plan) interlinked with the apex of one connected to the end of a respective arm of a more forward element.  The elements are formed of unusually large diameter steel rod (e.g. about 16mm instead of the prior thickness of about 11mm) with relatively unusually large loops and with a horizontal apex loop is that is an incomplete turn of about 270 degrees so as to provide for a specially effective sweeping and guiding action.  Each arm is provided at its end with a respective tooth at the end of a respective vertical loop for interlinking with the horizontal loop of the forward element.          These loops are all of at least about 5 cm radius;  the longer arm terminates in a trailing tooth with a trailing angle of about 15 degrees to the vertical to provide for normal harrowing, while the shorter arm also terminates in a trailing tooth with an angle of about 45 degrees to the vertical so as to be more self-cleaning when that is required.  The two arms are of different lengths so that the teeth of successive elements follow transversely-spaced paths.  The two teeth point in opposite directions so that the harrow is double-sided with different tooth actions for the two sides.  Such a harrow not only is more robust but avoids the difficulties experienced with prior harrows of "rear-end curl" at the speeds at which harrows are now employed.

Abstract: Improved Apparatus for the Reclamation of Slurry from the Bottom of a Storage Silo Abstract This is an improved apparatus used with a storage and reclamation apparatus which handles slurry formed of particulate matter and fluid.  The reclaim apparatus in-cludes a tank having a side wall and bottom.  The slurry is added into the tank and is subsequently removed from the tank by a downwardly facing bell mouth coupled through a pipe to a pump.  Fluidizing jets surround the bell mouth with a dilution control port mounted between the mouth and the pump.  The dilution control port is connected to a second pump in series with a source of fluids.  Process control apparatus measures the flow and density of the material being drawn into the mouth and adds or reduces dilution fluid in accordance with a set point so that a constant density is maintained at all times.  The improved version accepts the overflow from the tank into a second tank which has a second bell mouth mounted at the bottom of the tank.  Solids and fluids are sucked into the second bell mouth and used as the source of fluid for the dilution port of the first tank.

Abstract: ABSTRACT OF THE DISCLOSURE    A mechanical well jar is disclosed having inner and outer tubular members movable longitudinally relative to each other a limited distance for connecting in a pipe string.  Annular shoulders on the members engage to limit the relative longitudinal movement of the members.  A plurality of laterally spaced,  arcuate cam plates are attached to the inner surface of the outer member.  Each plate has a laterally extending U-shaped notch opening into the space between the plates and formed with curved outward-ly flaring sidewalls.  Rollers are mounted on the outer surface of the inner member to extend into the spaces between the cam plates for movement into the U-shaped notches to hold the members from longitudinal movement relative to each other.  Resilient means urge the members to rotate in the direction to move the rollers into the notches and allow the rollers to move out of the notches when a longitudinal force is imposed on the jar through the string sufficient for the flared sidewalls of the notches to provide a lateral component of force on the rollers suffi-cient to overcome the force of the resilient means and move the rollers out of the notches.  This allows the tubular members to move longitudinally relative to each other until the annular shoulders stop such movement and transfer the energy stored in the drill pipe to the other member and to the stuck pipe or fish below the jar.
