Abstract: A large scale video display of the present invention is designed to receive a standard NTSC video signal and display it on a large scale array of low cost, voltage or current controlled lamp transducers. The video signals are received by a video capture device which receives and digitizes the video signal. A host processor formats the digital data into a number of 16 bit data words each corresponding to a pixel. A coprocessor receives the 16 bit data words and reformats the data. The reformatted data is connected to a large scale display by a fiber optic connection. The display includes a number of transceivers which receive the formatted video data in a memory buffer. The transceivers also receive a board map from the coprocessor. The map indicates which light boards correspond to each part of the memory where the frame image is stored. This information is used by a number of controllers to determine which lights to turn on and at what level of brightness for any given time.

Abstract: Valve for separating liquids out of gases, as in gas-well-to-customer operations, being an improvement of the valve described in our U.S. Pat. No. 3,769,999 of Nov. 6, 1973, entitled "Liquid Separator System and Apparatus". The valve comprises a body with enlarged inlet chamber, a rising passage communicating therewith, a circumferential groove about the rising passage, downwardly-extending passages spaced on opposite sides of the rising passage and extending to an outlet chamber. The valve includes a head chamber with floating disc positioned within the same and seating atop the rising passage and circumferential groove, the floating disc being provided on the underside thereof with a radial groove to bleed off fluid in the head chamber and one or more further grooves to control fluid coming from the rising passage.
