    摘要： A smart shaft position encoder apparatus is described which can be used for measuring changes in liquid levels. The apparatus employs dedicated logic and decoder circuitry for converting the raw shaft sensor data into instrumentation-compatible format. The raw shaft sensor data is generated by a shaft pulse generator which provides a pulse for each discrete change in shaft position. The sequence of pulses indicates whether shaft rotation is in a clockwise or counterclockwise direction. A preferred shaft pulse generator includes three reed switches which are operated by four permanent magnets mounted on a support disk which rotates in accordance with the position of the shaft, such shaft being coupled to a float pulley when used as a liquid level recorder. A rotation position detector is coupled to the shaft interface and produces output pulses in response to the raw shaft position data from the shaft interface. Connected to the output of the rotation position detector is a rotation direction sensor, which produces an output signal indicative of the direction of shaft rotation. Also coupled to the output of the rotation position detector is a rotation detector for generating output pulses corresponding to true movements of shaft rotation. Logic circuitry combines the direction-of-rotation information provided by the rotation direction sensor and the unit-of-rotation information provided by the rotation detector to produce one of two output signals indicative of an incremental shaft rotation in a clockwise or counterclockwise direction. The logic circuitry is designed to produce output pulses compatible with existing data-recording equipment.

    摘要： A static electric charge removal of dispersal coating for ullage tapes having an outer polymeric surface. The coating is formed of carbon black and is applied to the polymeric surface of the ullage tape to disperse therefrom any static electric charge which may be generated thereon when used for measurement purposes in large tanks which can build up a high static charge therein. The carbon black coating is preferably acetylene black formed on the tape and simultaneously anchored thereto by passing the tape near a fuel rich acetylene flame. Any excess coating which is not anchored to the tape can be removed by wiping or other similar operation.The method of this invention can be used to apply an acetylene black coating to polymeric items such as fluorocarbon wire, tape, or other forms which can be passed in close proximity to a fuel rich acetylene flame.

    摘要： An apparatus is disclosed for measuring the rate of flow of a fluid or the volume of the fluid flowing past a point. The apparatus includes a first transducer device for measuring a fluid level upstream of a weir and a second transducer device for sensing and decoding an optically encoded Gray-scale disc rotated by the first transducer device to an angular position corresponding to the level of the fluid. The disc is provided with indicia thereon proportional to flow rates and corresponding to different fluid levels. The decoded signals obtained from the disc represent the rate of flow of the fluid. These signals are then integrated to indicate the volume of the fluid flowing past a point for actuating a fluid sampler or a recording device.

    摘要： A data transmission system for providing from a coarse analog signal representative of the cumulative angular position of a shaft, and from a fine analog signal representative of the noncumulative angular position of the shaft, a digital output indication of the cumulative position of the shaft. The coarse analog signal is utilized to provide the most significant digits and the fine analog signal is utilized to provide the least significant digits of the output display. Error correction means responsive to coarse and fine analog signals are provided for modifying the most significant portion of the output display to compensate for errors therein which may occur as a result of lower resolution in the encoder used to generate the coarse signal.

    摘要： The present invention is directed to a means for continually determining or detecting the level of a liquid in a vessel. In brief, the invention involves the use of a flexible tube suspended in a U-shape within a liquid whose level is to be determined. One end of the tube is attached to a float and the other extends above the liquid surface to the top of the vessel. The tube contains a resistance wire having an insulated return section and a regular conductor, such as a copper wire. The resistance wire and its return section are connected externally to a source of power forming a circuit. A freely movable pool of mercury is also disposed within the tube providing a connecting circuit between the resistance wire and conductor. A voltmeter potentiometer circuit is established across the resistance wire through the bare conductor and mercury pool. As the tube is raised and lowered in the liquid by the float, the mercury will seek the lowest portion of the tube and thus effect the current flowing between the wires and, correspondingly, the meter reading. The meter can be calibrated to read in volume, feet, or other desired scale.
