Abstract: END LOADING CAN CARTON          ABSTRACT For preventing damage to the tops and bottoms of end loading stacked can cartons, a reinforcing panel is affixed to the inside surface of the top or bottom walls of the carton or to both such walls so as to prevent coincidental can chimes on the upper ends of cans in a lower carton from damaging the top wall of its associated carton and the bottom wall of a carton stacked thereabove and without which the lower ends of the cans of the upper carton may cooperate with the chimes of the cans in the lower cartons to effect substantial damage to the top of the lower carton and to the bottom of the upper carton.  For facilitating entry of the cans into an end loading carton and for preventing damaging engagement between the chimes and the reinforcing panels, an inwardly extending embossment may be  formed in the carton wall adjacent the end edge of the reinforcement panel and if desired the end edge of the reinforcement panel adjacent the end of the carton through which the cans are loaded may be bevelled or may be otherwise configured so as to prevent damage to the carton due to loading of the cans.

Abstract: Abstract Of The Disclosure An enhanced oil recovery technique includes the prede-termination of a desired steam distribution within a steam flood pattern, which preferably is proportional to the vol-umes of oil in place within various sectors of an area of a subsurface formation.  These sectors are associated with the various producing wells of the steam flood pattern.  Initial steam distribution is then determined.  Subsequently, one or more of the producing wells has its production rate modified so that the final steam distribution within the formation will more closely approximate the predetermined preferred steam distribution.   A preferred technique for stimulating production from a given producing well includes the steps of initially notching and initiating a small unpropped fracture in the formation adjacent the well,  then perforating the well  over  the  entire depth of  the  formation,  and  sub-sequently creating a larger propped fracture at that same location after it has been determined that natural steam flow toward the particular producing well is not as great as is desired.

Abstract: ABSTRACT OF THE DISCLOSURE            Internal  stress  on  an  object  being  electroplated  is monitored continuously with a gauge.  The gauge includes a metal receptor which is employed as a second cathode in the electrodeposition process.  A separate plating current is supplied between  the  anode  and second cathode,  distinct from the separately controllable current between the anode and object being plated or electroformed.  The stress on the second cathode is measured with a strain gauge, and a stress  deviation  from  a  desired  plating  stress  is determined.  The currents between the anode and first and second  cathodes  are  adjusted  in  accordance  with  the-measured internal stress on the metal receptor to achieve a desired stress condition.    The internal stress is advantageously monitored with a foil resistance strain gauge.  The strain gauge is connected to a carrier disposed in parallel with the metal receptor. The carrier is rigidly connected at opposite ends to the metal receptor.   A  stress  transmission  link  centrally located between ends of the metal receptor and the carrier transmits the force applied by the electroplating material on the receptor to the carrier.  The strain gauge provides an  indication  of  the  stress  which  results  from  the electroplating.  The currents between the anode and first and second cathodes may be controlled in accordance with this stress measurement.

Abstract: ABSTRACT         Disclosed herein is a method and related system for controlling the injection of fluid into a plurality of spaced wellbores using a fluid distribution system to direct fluid from a fluid source to each of the spaced wellbores.  In the method, high/low fluid flow rate limits and high/low fluid pressure limits for each wellbore are determined and inputted into an RTU.  The fluid flow rate and fluid pressure for each wellbore are measured at the fluid distribution system and the measured fluid flow rate and the fluid pressure for each wellbore are compared to the determined limits.  Thereafter, the flow of fluid to each wellbore is adjusted at the fluid distribution system for those wellbores that have a measured fluid flow rate and/or fluid pressure outside of the determined limits and the adjustment is continued until the measured flow rate and fluid pressure are within the determined limits.
