Abstract: LEAN PRECHAMBER OUTFLOW COMBUSTOR WITH           Abstract of the Disclosure A combustion apparatus for gas turbine engines particularly adapted to reduce emissions to meet automotive requirements.  The fuel is laid on the wall of a cylindrical prechamber and evaporated from the wall by combustion air which is introduced through a swirler at the upstream end of the pre-chamber.  The inner surface of the prechamber is artificially roughened by a grid of grooves to improve fuel evaporation.  The fuel is laid on the wall from an annular manifold extending around the upstream end of the prechamber through tangential orifices leading from the manifold into the interior of the prechamber.  More air enters through entrance ports distributed around the prechamber toward its downstream end.  The resulting lean fuel-air mixture is delivered past an annular flow dam at the outlet of the prechamber into a domed combustor wall forming a combustion or reaction zone which is abruptly enlarged from the prechamber.  Still other air bypasses the prechamber and is directed through ports formed in the dome of the combustor wall where swirlers direct the bypassed air into prevaporized fuel and air from the prechamber.  The structure reduces pressure drop across the flow dam while enhancing Abstract - Cont'd turbulent flow, recirculation, and good mixing in the reaction zone.  A dilution zone downstream of the reaction has a circumferential array of dilution air ports which are of such shape as to be varied non-linearly in area by a sliding ring valve.  The sliding ring valve is coupled to a second sliding ring valve which varies the area of the air entrance ports in the prechamber in reverse sense to the dilution air ports.

Abstract: ABSTRACT OF THE DISCLOSURE      A method for filling containers with a base food product which self-supports a topping or sauce includes the steps of placing a transparent removable lid on top of an empty con-tainer and providing an opening in the bottom of the container.          The container is inverted so the lid is on the bottom and the opening is on top.  The topping is introduced to the container through the opening to form a layer overlying the inside surface of the lid.  The remainder of the inverted container is then filled with a base food product and the opening is sealed.  The container is then re-inverted to a right-side-up position and the base food product self-supports the topping beneath the removable lid.  The base product can be a gellable food product, such as flavored gelatin which gel sets while the containter is inverted to attain a sufficient gel strength to self support a more dense topping when the container is re-positioned in the right-side-up position.  Containers can be filled with base products of pudding and cheese in a similar manner.  In another embodiment, the topping can be a sauce, and the contents of the container are frozen while the con-tainer is inverted.  Containers can be filled with ice cream and toppings in a similar manner.  When the topping is formed as a layer on the inside of the lid it displaces air adjacent the lid and creates a partial vacuum that adheres the topping to the undersurface of the lid when the container is re-inverted to the right-side-up position.  By eliminating an air space between the topping and the lid, discoloration of the food is inhibited and the topping is clearly visible to consumers through the see-through lid. ?07-1
