Abstract

Abstract A microwave oven cooking time scale for predetermining cooking time for a known amount of food to reach a predetermined temperature for a predetermined heating efficiency of the food in a microwave oven. The microwave oven cooking time scale includes a balance beam scale with food positioned at a fixed point on one side of the balance beam and a counterweight adjustable along the length of a cylindrical information chart rotatably engaged on the balance beam. The counterweight includes a pointer which indicates on the rotatable cylindrical informational chart the proper cooking time to reach a predetermined particular temperature. The cylindrical information chart is divided as a function of time and temperature on an x-y axis and can be subdivided as a function of cooking efficiency, cooking power, and cooking moisture on the y axis. The cylindrical information cylinder is replaceable for different models or manufacturers of microwave ovens. The cylindrical information chart can also compensate for the weight of the cooking container.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 312 words
Microwave oven cooking time scale for determining the length of time to cook a particular piece of food as a function of a predetermined temperature comprising: a. balance beam scale means including a fulcrum support means, a fulcrum point positioned on said fulcrum support means, a cylindrical means supported on said fulcrum point and including a downwardly extending pivot means and balance beam means extending longitudinally and at right angles from both sides of said pivot means; b. food container means positioned on one side of said balance beam means for weighing food on said scale; c. cylindrical information microwave chart means rotatably engaged over the other end of said balance beam means and being of a weight to substantially equal and compensate for said food container means in which said food is weighed and including longitudinally extending rod including a knurled knob at one end, and an informational chart columnly divided as a function of temperature and time and subdivided into at least one subdivision column for cooking efficiencies of food, each subdivision corresponding to low efficiency, medium efficiency, and high efficiency of food for microwave cooking; d. counterweight means including a cylindrical member engaged over said chart means and including a transparent window, a knob extending horizontally outward, and pointer extending vertically upward and encompassing a portion of said transparent window; and, e. housing means covering said scale including a rectangular configuration having a horizontal rectangular window substantially corresponding to the diameter and length respectively of said cylindrical information chart means and a substantially upward extending rectangular vertical slot to accommodate said longitudinal rod extending from said chart means whereby said food is placed on said container means and said counterweight means is respectively adjusted to substantially align said information cylinder means with said horizontal window means thereby indicating the temperature, time and efficiency of the food microwave cooking conditions.
Claim 2
Dependent Claim 312 words
Microwave oven cooking time scale for determining the length of time to cook a particular piece of food as a function of a predetermined temperature comprising: a. balance beam scale means including a fulcrum support means, a fulcrum point positioned on said fulcrum support means, a cylindrical means supported on said fulcrum point and including a downwardly extending pivot means and balance beam means extending longitudinally and at right angles from both sides of said pivot means; b. food container means positioned on one side of said balance beam means for weighing food on said scale; c. cylindrical information microwave chart means rotatably engaged over the other end of said balance beam means and being of a weight to substantially equal and compensate for said food container means in which said food is weighed and including longitudinally extending rod including a knurled knob at one end, and an informational chart columnly divided as a function of temperature and time and subdivided into at least one subdivision column for cooking efficiencies of food, each subdivision corresponding to low efficiency, medium efficiency, and high efficiency of food for microwave cooking; d. counterweight means including a cylindrical member engaged over said chart means and including a transparent window, a knob extending horizontally outward, and pointer extending vertically upward and encompassing a portion of said transparent window; and, e. housing means covering said scale including a rectangular configuration having a horizontal rectangular window substantially corresponding to the diameter and length respectively of said cylindrical information chart means and a substantially upward extending rectangular vertical slot to accommodate said longitudinal rod extending from said chart means whereby said food is placed on said container means and said counterweight means is respectively adjusted to substantially align said information cylinder means with said horizontal window means thereby indicating the temperature, time and efficiency of the food microwave cooking conditions.
Claim 3
Dependent Claim 32 words
The microwave oven cooking time scale of claim 1 wherein said cylindrical information chart is subdivided as a function of low, medium, or high moisture contents of said food for microwave cooking.
Claim 4
Dependent Claim 27 words
The microwave oven cooking time scale of claim 1 wherein said cylindrical information chart is subdivided as a function of particular types of food for microwave cooking.
