Abstract: A method of preservation and presentation including the steps of positioning a perishable product having a significant porosity and permeability into a gas impermeable package in the presence of a first agent, thereafter sealing the product in the package in the presence of the agent under a positive pressure and maintaining gas communication between the product and the first agent for a time necessary for the concentration of the first agent to be reduced by 50%.

Abstract: A method is disclosed for enhancing the marketable characteristics for a given perishable product prior to or after the product has been placed in a gas-tight consumer-ready package. More specifically, the method of the present invention contemplates the use of one or more agents or mixtures thereof which are introduced into gas communication with a perishable meat product in a selected concentration based on a number of variables including moisture content, muscle type and surface area of said product.

Abstract: An interlaced raster-scanned color cathode ray tube display in which flicker is reduced by temporally off-setting one of the colors (preferably red) so that normally even-field data for that color is displayed in the odd field and normally odd-field data for that color is displayed in the even field. The temporal shift can be either before or during storage of the bit patterns or during or after reading of the bit patterns.The resulting positional shift of one scan line of the temporally shifted color is compensated for by using the static and/or dynamic convergence circuitry.

Abstract: A colorimetric analyzer automatically and continuously measures the transmission of light through a sample which has been mixed with reagents. Precise volumes of the sample are repeatedly measured by a siphon tube. Volumes of the reagent are added to the sample at different times in a measuring cycle. The reagent is added at different places in the analyzer so that it is possible for two different time-consuming reactions to proceed simultaneously. The mixed reagent and sample is supplied to a measuring cell which includes a source of light and a photocell. The distance between the source of light and the photocell are adjustable to accommodate analyses of mixtures with widely varying light transmission while providing a full scale output indication. The output of a photocell is applied to a sample and hold circuit during time intervals when the reactions of the reagents with the sample have been completed.
