  • Patent number: 6468575
    Abstract: A tongue rack includes a frame with a plurality of troughs supported on the frame. Each trough is generally U-shaped in cross-section and sloped, with the open upper end of the trough located above a closed lower end of the trough. A tongue placed in the trough will shorten in length and increase in thickness as it is chilled. The method of the invention includes extracting a beef tongue from an animal and positioning the tongue into the sloped trough with the base end of the tongue against the closed end of the trough and the tipped end of the tongue proximal the open end of the trough, prior to rigor mortis setting in on the tongue.

  • Patent number: 6467302
    Abstract: The improved refrigeration system of the present invention includes an accumulator with a diffuser pipe extending downwardly into the upper end of a vapor refrigerant tank, the diffuser pipe extending from an evaporator and discharging vapor refrigerant therefrom into the tank. The diffuser pipe includes a lower end located within the interior of the tank which is expanded in diameter relative to the upper end, thereby reducing the velocity of fluid flowing through the pipe and entering the accumulator tank. A diffusion plate is mounted in the lower end of the diffuser pipe, to further diffuse fluid flowing therethrough.

  • Patent number: 6397892
    Abstract: An unloader includes a first volume bottle with a cavity formed therein of predetermined volume, and a port in the forward end with a plug operably mounted to selectively open and close the port. A second volume bottle is stacked on the first volume bottle and has a port in the forward end with a plug operable to open and close the second bottle port. The second bottle is arranged such that the second port will fluidly connect the first and second bottles. Actuators are connected to the plugs in the first and second bottles to selectively open only the first bottle or both bottles together, to thereby provide a two stage internal clearance for the reciprocating compressor cylinder.
