    摘要： A moisture content measuring apparatus and method wherein a sensor station produces calibration data corresponding to measurements of light at two different wavelengths reflected from a material, and the calibration data is then transferred to a hand held computer. The moisture content of a sample of the material is measured and input to the hand held computer. The process is repeated after changing the wetness of the material, and the hand held computer creates a table correlating reflection data to moisture content. The table is transferred to the sensor station which then continuously generates signals representing moisture content in response to real time reflection data and the table. The cost effectiveness of the sensor stations readily facilitates the use of a dedicated sensor station at each of a plurality of conveyors carrying different materials to be combined into a composite of predetermined proportions by weight. Based on the real time moisture contents of each material, the respective flow rates are adjusted to compensate for moisture in order to produce the predetermined proportion.

    摘要： A gyratory crusher includes a control system, an upper frame portion having a bowl liner, and a crushing head having a mantel such that a crushing chamber having a gap is formed between the bowl liner and the mantel. The control system includes detecting means for detecting a pre-defined bowl float condition of the crusher, adjusting means for automatically adjusting a width of the gap to thereby eliminate the bowl float condition, and monitoring means for determining magnitude and direction of changes in the width of the gap by monitoring rotation of the bowl liner relative to the upper frame portion. The control means is adapted to automatically adjust the width of the gap to operatively compensate for a wearing rate of the bowl liner and the mantel and to terminate operation of the crusher should rate of bowl float conditions exceed a pre-determined quantity.

    摘要： A coin diameter discriminating device wherein a coin is received in a coin transport mechanism which is rotated by a motor at an accurately controlled angular velocity. By such arrangement, the coin is carried along a predetermined path at an accurately controlled or regulated velocity past at least one optical sensor that provides a change of state output upon detecting an edge of the coin. The sensor is arranged to start a time counter that is stopped by a predetermined reference event such as the coin transport mechanism having rotated to a predetermined angular orientation. The time count in the counter therefore corresponds to the angular orientation of the coin transport mechanism at the time of detecting the coin edge, which also accurately corresponds to the diameter of the coin. The time count is then compared to corresponding time count ranges each of which relates to known standards of an acceptable coin denomination.

    摘要： A method and apparatus for discriminating and collecting coins wherein an inserted coin is received in a notch of a rotary disk. Upon sensing the insertion of a coin into the notch, a motor rotates the disk through a predetermined arc to a predetermined angular orientation where a decision is made whether to accept or reject the coin based on coin characteristics such as the sensed diameter of the coin and metal content. If the coin is accepted, the disk is rotated to an angular orientation where the coin falls from the notch into a coin collection box. However, if the coin is rejected, the disk is rotated in the opposite direction to an angular orientation where the coin falls into a coin return chute. Sensors are also provided to sense the presence of the coin in the notch on the way back to the initial angular orientation. If the coin failed to fall out for any reason, another attempt is made to collect the coin. If still unsuccessful, a fault is indicated, and the apparatus remains in an inoperative state. Removal of the coin from the coin return chute is also sensed before another coin can be inserted.
