摘要： An apparatus for determining the reflectivity of the tailings from a coal flotation cell to optimize the cell operation. A bifurcated fiber optic cable has ends connected to a light source and a photoconductor, with a scanner end of the cable being submersed in a coal slurry. Light transmitted to the scanner end of the cable is backscattered to the photoconductor to function as a detector to determine the coal content of the tailings and through a process controller, frother and collector addition to the cell is monitored. An ultrasonic energy vibration is periodically transmitted to the scanner end of the cable to remove deposits thereon to optimize detector operation.

摘要： A device that easily fits on a refuse container and will sound an audible alarm when silverware that has been magnetized and likely hidden within other refuse falls through a sensing cavity on its way to the refuse container. This device will not trigger on any other metallic or non-metallic material due to its sensing of only passing magnetic fields. Silverware material conducive to magnetization can be easily magnetized and will retain such characteristics for a long period of time making it a practical way to differentiate silverware from other metallic refuse. The device also uses a sensing switch that activates the same audible alarm when an attempt is made to bypass the unit by removing it from the refuse container. A key switch provides security that enables alarm reset only by authorized personnel. A low battery indicator is provided by the pulsing of the audible alarm. The unit is portable, low maintenance, and requires no adjustments.
摘要翻译： 当被磁化并且可能隐藏在其他垃圾中的银器在通往垃圾容器的途中通过感测腔落下时，容易装在垃圾容器上并且将发出声音报警的装置。 该装置由于仅感测到通过的磁场而不会在任何其他金属或非金属材料上触发。 有助于磁化的银器材料可以容易地被磁化，并且将长期保持这种特性，使其成为区分银器与其他金属垃圾的实用方式。 该设备还使用一个感测开关，当尝试通过从垃圾箱中取出设备来绕过设备时，激活相同的声音报警器。 钥匙开关提供安全保护，只能由授权人员进行报警复位。 低电量指示器是由声音报警器的脉冲提供的。 本机是便携式的，维护少，不需要调整。

摘要： The method and apparatus for mapping mine excavation or tunnel entry conditions by mounting an array of sensors on a vehicle some of which provide knowledge of the vehicle location in the entry and others of which provide knowledge of entry conditions and by interpreting data collected from the sensors, a map can be generated of the entry strata for a given vehicle location in the entry. This map can be compared with similarly generated maps to indicate changes in the entry condition.

摘要： Mine panel alignment is controlled by recording the electromagnetic phase modulation and/or signal attenuation between spaced distant transceivers in the panel and a transceiver on a cutting machine to measure the distance between the transceivers. Through trilateration, the position of the cutting machine with respect to the known fixed locations can be determined and adjustments made to the cutting machine functions to maintain desired panel alignment.
