Abstract
Abstract A method of measuring fat content of meat includes the steps of immersing a meat sample in a liquid, and detecting the amount of displacement of the liquid by the meat sample, the variance of such displacement as a function of fat content being predetermined, whereby the fat content is determinable from the detected displacement.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
149 words
In apparatus for measuring fat content of meat, the combination comprising (a) a first container to receive liquid into which a meat sample is immersed when the meat sample is placed in the container, and (b) means associated with the container for indicating the amount of displacement of the liquid by the meat sample, the variance of such displacement being a function of fat content to be determined, whereby the fat content can be determined from the detected displacement, (c) said means including a liquid height gage communicating with the container interior, there being meat fat content calibration indicia vertically spaced on the gage to indicate fat content percentages, and there also being a piston pump on a lid for the container, said lid providing means via which liquid is accessed into the container, said height gage projecting upwardly through the lid to receive liquid displaced by the pump.
Claim 2
Dependent Claim
149 words
In apparatus for measuring fat content of meat, the combination comprising (a) a first container to receive liquid into which a meat sample is immersed when the meat sample is placed in the container, and (b) means associated with the container for indicating the amount of displacement of the liquid by the meat sample, the variance of such displacement being a function of fat content to be determined, whereby the fat content can be determined from the detected displacement, (c) said means including a liquid height gage communicating with the container interior, there being meat fat content calibration indicia vertically spaced on the gage to indicate fat content percentages, and there also being a piston pump on a lid for the container, said lid providing means via which liquid is accessed into the container, said height gage projecting upwardly through the lid to receive liquid displaced by the pump.
Claim 3
Dependent Claim
149 words
In apparatus for measuring fat content of meat, the combination comprising (a) a first container to receive liquid into which a meat sample is immersed when the meat sample is placed in the container, and (b) means associated with the container for indicating the amount of displacement of the liquid by the meat sample, the variance of such displacement being a function of fat content to be determined, whereby the fat content can be determined from the detected displacement, (c) said means including a second container to contain a measured volume of source liquid to be drained into the first container when the second container is elevated above the level of the first container, and said means includes a liquid level height gage communicating between said containers and through which liquid may drain to the first container, the height gage supporting the second container spaced above the first container.
Claim 4
Dependent Claim
149 words
In apparatus for measuring fat content of meat, the combination comprising (a) a first container to receive liquid into which a meat sample is immersed when the meat sample is placed in the container, and (b) means associated with the container for indicating the amount of displacement of the liquid by the meat sample, the variance of such displacement being a function of fat content to be determined, whereby the fat content can be determined from the detected displacement, (c) said means including a second container to contain a measured volume of source liquid to be drained into the first container when the second container is elevated above the level of the first container, and said means includes a liquid level height gage communicating between said containers and through which liquid may drain to the first container, the height gage supporting the second container spaced above the first container.
Claim 5
Dependent Claim
23 words
The combination of claim 2 including a means in the first container to be rotated for dispersing ground meat in the first container.
