    摘要： A method and apparatus for determining the oxygen uptake rate of bacteria in a body of liquid incorporates withdrawing a sample of the liquid into a chamber where a dissolved oxygen probe is located, the probe outputting a signal which is a function of the amount of dissolved oxygen in the sample. The sample is aerated, and a computer is used to sample the signal at regular intervals to produce a series of time-separated values corresponding to the sampled signals, the values representing the dissolved oxygen in the sample at the timed intervals. Repeated samples can be taken, so that the O.U.R. can be monitored on a continuing basis. The O.U.R. information can be used to control the rate of aeration in a tank, or to control the rate of recycling of activated sludge from the downstream to the upstream end of the tank.

    摘要： A modular skid frame for supporting cement pumping equipment includes three interlockable sections which, when assembled, define two longitudinal support members and a plurality of transverse support members. One end of the skid formed by one of the interlockable sections is adapted to break down into two lateral subsections. A sleeve-like interfit is provided between joined members and bolt and bracket means are provided to disengageably secure adjacent endwise aligned support members together. The pumping equipment is arranged to maximize maintainability and transportability by positioning one engine on each lateral subsection at one end of the skid and having one pump on each of the other two interlockable sections. A displacement tank is supported on the skid above the pumps. The skid and equipment can be particularly adapted to operate with numerous kinds of off-skid mixing equipment.

    摘要： 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.
