    Abstract: A machine and method for treatment of vertically disposed surfaces of large dimension with dry particulate material comprising means for throwing the dry particulate material at high velocity in the direction toward said surface, a housing enclosing said throwing means having an opening through which the particulate material is thrown against said surface, means for establishing a sealing relationship about said opening between the housing and said surface to confine the particulate material, dirt and dusts within the sealed space, means for collecting the spent particulate material at the bottom portion of the housing and for introducing air into the housing for air washing the spent particulate material to remove dirt and dusts, recycling the washed particulate material for feed to the throwing means, a dust collector for receiving the dirt and dust from within the housing for separation thereof and means for maintaining subatmospheric conditions within the housing to guide the air flow through the housing and about said sealing means to minimize the exhaust of dirt and dust into the atmosphere and in which the support means for said housing includes means for movement of the housing in the vertical direction, means for movement of the housing in the horizontal direction and means for movement of the housing in the direction toward and away from the surface and means for mounting the housing for rocking movement about its pitch and yaw axes to adjust the housing with change in contour of the surface, and sensing means about the opening automatically to adjust the housing for change in contour about the pitch axis and/or the yaw axis and for movement of the housing in the direction towards and away from the surface and for abutting off the feed of particulate material in the absence of a sealing relationship between the housing and surface.

    Abstract translation: 一种用于用干燥颗粒材料处理垂直布置的大尺寸表面的机器和方法，包括用于以高速向所述表面方向投掷干燥颗粒材料的装置，封闭所述投掷装置的壳体，该壳体具有开口，颗粒材料通过该开口 扔在所述表面上，用于建立围绕所述壳体和所述表面之间的所述开口的密封关系的装置，以将颗粒材料，污垢和灰尘限制在密封空间内，用于在壳体的底部收集废颗粒材料的装置， 将空气引入壳体中以空气清洗废颗粒材料以除去污垢和灰尘，将经清洗的颗粒材料再循环到投料装置中，用于从壳体内接收污物和灰尘以进行分离的集尘器和用于分离的装置 在外壳内低于大气条件以引导空气f 低通过壳体和围绕所述密封装置，以最大限度地减少污垢和灰尘排入大气中，并且其中用于所述壳体的支撑装置包括用于沿垂直方向移动壳体的装置，用于使壳体在水平方向上移动的装置 用于沿着朝向和远离表面的方向移动壳体的方向和装置，以及用于安装壳体以围绕其俯仰和偏转轴线摇摆运动的装置，以便随着表面轮廓的改变来调节壳体，以及围绕开口的感测装置 自动地调整壳体以改变俯仰轴线和/或偏转轴线的轮廓，并且用于沿着朝向和远离表面的方向移动壳体，并且用于在没有密封关系的情况下抵靠颗粒材料的进给 在外壳和表面之间。

    Abstract: A control system for the passage of abrasive particles into contact with the surfaces of moving objects wherein an electromagnetic valve means is employed for regulating the rate of delivery of the particles. The valve means is operated by an electrical circuit which varies the influence of the magnet on the particles. The variations in influence are achieved in the circuit through the use of a control device which is tied to drive means employed for moving the objects past the mechanisms delivering the abrasive particles. The flow of particles can thus be regulated in accordance with changes in speed of the objects.
