    Abstract: The present invention provides a level indicator for indicating the level of bulk materials such as molding sand which are stored in a bin. The indicator employs a pneumatically operated sensor having a J-shaped output tube which is mounted in the bin to supply a stream of air to an input tube across a gap between the J-shaped output tube and the input tube when no bulk material is present at the level of the indicator. When the bulk material is present at the level of the indicator, it obstructs the gap between the output and input tubes. This causes a pressure change at the input tube which can be detected by suitable means coupled to the input tube to provide a control signal. The control signal can be utilized in conjunction with filling apparatus to automatically refill the bin when the level falls below a predetermined level at which an indicator is installed. A second level indicator can be installed near the top of the bin to provide a control signal which will automatically stop associated filling apparatus when the bulk material has reached the level of the second indicator and the bin is filled.

    Abstract translation: 本发明提供了一种液位指示器，用于指示存储在箱中的诸如型砂的散装材料的水平。 该指示器采用具有J形输出管的气动传感器，该传感器安装在箱中，以便在不存在散装材料时将空气流输送到跨越J形输出管和输入管之间的间隙的输入管 在指标的水平。 当散装材料存在于指示器的水平面时，它阻碍输出管和输入管之间的间隙。 这导致输入管的压力变化，其可以通过耦合到输入管的适当装置来检测以提供控制信号。 控制信号可以与填充设备一起使用，以便当液位低于安装指示器的预定水平时自动重新填充箱。 第二级指示器可以安装在垃圾箱顶部附近，以提供控制信号，当大容量材料已达到第二个指示器的水平面并且垃圾箱已经被填满时，该控制信号会自动停止相关的灌装设备。

    Abstract: This invention relates to apparatus for feeding upright stacks of can ends to an upright column from the leading end of which column, can ends are fed one at a time in succession to, for example, a can seaming machine. The apparatus includes columnholding means for location of said upright column, conveyor means for carrying a supply of upright stacks of can ends for replenishing said column, said column-holding means being located below the level of said conveyor means, positioning means for positioning each stack in turn on top of the diminished column of can ends, and control means responsive to the height of the column for operating the conveyor means to feed a stack of can ends towards the column holding means to enable the positioning means to locate the said stack on the column and so replenish said column.
