IPC: E21B43/24
Filed: 1989-12-28
Abstract: A process for closing pores in a bottom water zone where steam is directed so as to by-pass a zone of the formation containing hydrocarbonaceous fluids.  Once a portion of the bottom water zone has reached a temperature in excess of about 300°F, steam entry is ceased.  Afterwards, a temperature activated gellable composition is placed into the bottom water zone.  When the composition reaches that portion of the bottom water zone where a temperature in excess of about 300°F has been reached, the composition activates and forms a rigid gel.  Thereafter, a steam flooding method is commenced.  Steam is diverted from the bottom water zone and into an upper zone containing hydrocarbonaceous fluids.

Title: Ventless hood for a deep fat fryer
Inventor: MOORE DAVID O
IPC: F24C15/20
Filed: 1990-02-28
Abstract: ABSTRACT   A ventless hood for a commercial deep fat frying pressure  cooker  having  a  pot  in which cooking  is performed by the use of a heated cooking oil bath and steam under pressure derived from the moisture in the food being  cooked.   The hood comprises  a  vertical portion  at  the  rear of the cooker and a forwardly extending   open-bottom   portion   spaced   from   and overlying the pot.   The forwardly extending portion of  the hood supports  a  pair  of  angularly  related baffle filters surmounted by a metallic mesh filter and a charcoal filter.  A fan in the vertical portion of  the  hood  draws  ambient  air  and cooking  gasses through  these  filters.   A  water  tank  is  mounted behind the cooker together with a pump to recirculate the  water  in  the  tank  through  a  heat  exchanging radiator located between the filters and the fan to cool  the water.   During  the  cooking  cycle  excess steam and vaporized cooking oil are introduced into the water bath which acts as a scrubber and condenses the majority of the steam and vaporized cooking oil.     Residual    non-condensables,    uncondensed    steam, vaporized cooking oil and unabsorbed odors are vented from the water tank directly to the bottom of the forward  hood  portion.   At  the end of the cooking cycle all of the cooking gasses are vented into the water bath prior to opening of the cooking pot.
