Abstract: A gauge for determining the maximum width of a load of material supported on a railway car has an elongated, upstanding boom and car side sill engaging feet extending transversely of one side of the boom. A gauge support is mounted on the opposite side of the boom to facilitate sliding the gauge along a side sill so as to gauge any extent of the material beyond a predetermined fixed distance at which the terminal end of the feet are set from the boom to thereby determine the maximum width of the load of material on the car.

Abstract: A film development system including a container for development fluid, a lid for the container, a computer, a temperature sensing probe and a visual time display. The temperature sensing probe extends downwardly into the container and monitors the temperature of a development fluid therein. The temperature probe transmits data to the computer which is adapted to calculate the time remaining for a selected film development step corresponding to the temperature indicated by the temperature probe. The computer transmits signals to the visual display where the temperature of the development fluid and the time remaining until completion of the film development step are displayed.
