    • Non-contact temperature monitoring of a rotating machine element such as a brake drum by an apparatus including a ferromagnetic insert in the rotating machine element and shielded therefrom by non-magnetic, heat conductive material. An inductive pulse transmitter is arranged to form an air gap with the rotary moving insert. The transmitter delivers an electrical pulse in response to each passage of the insert during rotation thereof. The pulses are amplified and shaped before passing into an integrating circuit wherein the pulses form the control signal connected to a relay for interrupting a power supply to a drive for the rotating machine element when the temperature thereof exceeds Curie Point of the ferromagnetic material. When the Curie Point is exceeded, the insert becomes paramagnetic and fails to produce pulses and disrupts the control signal for the relay.
    • 通过包括在旋转机器元件中的铁磁插入件并且由非磁性导热材料屏蔽的设备的设备对诸如制动鼓的旋转机器元件进行非接触式温度监视。 电感式脉冲发射器布置成与旋转移动插入件形成气隙。 发射器响应于插入件在其旋转期间的每个通道而递送电脉冲。 脉冲在进入积分电路之前被放大和成形,其中脉冲形成连接到继电器的控制信号,用于当其温度超过铁磁材料的居里点时,切断用于旋转机器元件的驱动器的电源。 当超过居里点时,插入件变为顺磁性,不能产生脉冲并中断继电器的控制信号。

    • A coal plow that can be moved lengthwise in opposite directions along a coal face has an axle projecting horizontally from its mining side. A tool supporting member is mounted on the axle for rocking parallel to the guide beam of the plow. At each end of the supporting member there is a plurality of independent blade holders disposed in a row extending upwardly beside the beam. The lowest blade holder in each row supports a bottom plow blade for engagement with the foot wall of the mine. Cutter blades have inner ends secured to the rest of the holders and have outer ends projecting toward the adjacent ends of the guide beam. Each of these holders is hinged to the supporting member on a substantially vertical axis so that the outer ends of the blades can swing laterally away from the guide beam.
    • 沿煤层沿相反方向纵向移动的煤犁具有从其采矿侧向水平方向突出的轴。 工具支撑构件安装在轴上以平行于犁的引导梁摇摆。 在支撑构件的每个端部处具有多个独立的刀片保持器,其设置成在梁的旁边向上延伸的一排。 每排中最低的刀片支架支撑底部犁刀,用于与矿井的脚墙接合。 刀片具有固定到其余保持器的内端,并且具有朝向引导梁的相邻端突出的外端。 这些保持器中的每一个在基本上垂直的轴线上铰接到支撑构件,使得叶片的外端可以横向摆动地远离引导梁。

    • A coal cutting machine extends across a conveyor that is spaced from the working face of a coal mine, and across most of the space between it and the working face. One side of the machine is supported on the side wall of the conveyor along its gobbing side. The opposite side of the machine is supported by a skid on the foot wall of the mine. Between the conveyor and the working face the machine houses a winch and drive motor, and a cutter head housing is connected to an end of the machine body in the same area and contains a horizontal axle that projects from the conveyor side of the housing. Mounted on this axle is the inner end of an arm that extends lengthwise of the machine away from the cutter housing. The outer end of the arm carries a roll cutter that extends laterally from it across the housing.
    • 煤切割机延伸穿过与煤矿的工作面间隔开的输送机,并且跨越其与工作面之间的大部分空间。 机器的一侧沿着输送带的侧壁支撑在输送机的侧壁上。 机器的相对侧由矿井脚壁上的滑道支撑。 在输送机和工作面之间,机器容纳绞盘和驱动马达,并且刀头壳体在同一区域内连接到机体的端部,并且包含从壳体的输送机侧突出的水平轴。 安装在该轴上的是臂的内端,该臂的端部从机器的纵向延伸远离切割器壳体。 臂的外端带有一个从其横向穿过壳体延伸的辊切割器。

    • Motor control system for a mining machine of the type in which a cutting element is driven by a first electrical motor and the mining machine is advanced into a coal face by a second motor. The system is characterized in that the torque and speed of the second motor are reduced both when the cutter element drive motor is idling as well as when the cutter motor is overloaded. The arrangement is such that as the cutting element approaches the coal seam and is idling, the speed of the advancing drive motor is relatively low; when the cutter enters the coal face and the current to the cutter drive motor increases, the speed of the advancing drive motor is also increased; and when the cutter element drive motor is overloaded, the advancing drive motor is reversed to withdraw the cutting element from the coal face and thereafter again advances the cutting element into the coal face in a pulsing or reciprocating motion.
    • 一种采矿机的电动机控制系统,其中切割元件由第一电动机驱动并且采矿机通过第二电动机进入煤面。 该系统的特征在于,当切割器元件驱动电动机怠速时以及当切割器电动机过载时,第二电动机的转矩和转速都降低。 这种布置使得当切割元件接近煤层并且空转时,推进驱动马达的速度相对较低; 当刀具进入煤面并且切割驱动电动机的电流增加时,前进驱动电动机的速度也增加; 并且当切割元件驱动马达过载时,推进驱动马达反向,从煤面撤出切割元件,然后再次以脉冲或往复运动将切割元件推入煤面。
