Abstract: An outdoor broiling, cooking and grilling device with four separate cooking zones capable of cooking between 200 F to 1200 F offering the user a wide range of cooking options from traditional grilling in the normal range of 200-500 F to high temperature searing in the 800-1200 F range. A method and apparatus capable of directing a burner flame to create optimal searing temperatures and conditions below the burner flame envelope, as well as optimal grilling and cooking conditions above the burner flame envelope depending on user setting.

Abstract: A cooking system including a housing assembly provided with lid, which define a plurality of cooking zones and a thermal energy zone. One of the cooking zones is located beneath the thermal energy zone to utilize convection thermal energy transfer and radiant thermal energy transfer during operation of the cooking system. A blower assembly of the cooking system forces a fluid through at least one fluid flow path of the housing assembly and the thermal energy zone, to provide a superheated fluid having a temperature of about 800° F. to about 1200° F. to at least one of the cooking zones.

Abstract: A trussing apparatus comprises a main portion coupled to opposing end portions. The main portion includes at least one receiving member and at least one support member. A curvature of the at least one receiving member permits various sizes, shapes, and cuts of meat to be disposed in the trussing apparatus. The at least one receiving member has at least one hook-like formation configured to cooperate with one or more restraining elements to secure at least one piece of meat in the trussing apparatus.

Abstract: A method for the on-line cleaning of a heat exchanger used with petroleum process fluids which create coke deposits of asphaltenic origin on the exchanger tubes. The asphaltenes are removed by re-dissolution in a solvent oil of high solubility power for the asphaltenes. Certain asphaltenic crudes are useful as solvents in view of their chemical similarity to the asphaltene coke precursors; also useful are refined petroleum fractions such as gas oils which are also characterized by their solvency for asphaltenes. The solvent oil may be admitted to the heat exchanger following withdrawal of the process fluid and then allowed to soak and dissolve the asphaltene coke precursors after which the resulting solution may be withdrawn and the exchanger returned to use without being at any time disconnected from its associated process unit.
