Abstract:
10,731. Richardson, T. M. April 30. Milk cans.-The apparatus is for discharging measured quantities of liquid from milk cans &c. by forcing in a definite quantity of air. In the form shown, the can A has a screw cap B, in which is carried two conical tubes C, C' adapted to receive perforated elastic stoppers D, D . The former is connected to the air-forcer F, while the discharge tube E slides through the other so as to be adjustable according to the depth of the vessel. I is a metal or india-rubber cap for preventing drip, and this and the air-forcer are connected by chains H, H with the ring G sliding on the tube E. A plain elastic stopper or a screw ring to receive an elastic stopper may be substituted for the screw cap. The arrangement prevents dripping even when the cap is not on.
Abstract:
A method for monitoring a process output with a highly abridged spectrophotometer. The method includes securing spectral data for each spectral primary used in a process, measuring spectral data with a highly abridged spectrophotometer for a sample produced by the process, determining an estimated weight for each spectral primary in the sample, and computing spectral data representative of the sample based on the secured spectral data and the determined estimated weight for each spectral primary in the sample.
