Abstract
A control for controlling the level in one of two tanks used in a ceramic hot molding machine which requires transfer of a ceramic slurry from one tank to the other in a continuous molding process. More particularly the present invention relates to an apparatus which automatically shuts off the transfer process when the working tank is filled a predetermined amount.
Claims9
In a ceramic slurry hot molding machine having a working tank and a preparation tank for holding the slurry, and wherein transfer of material from said preparation tank to said working tank is required in the process, the improvement comprising an apparatus for determining when a desired amount of slurry has been transferred to said working tank, including a tank support for mounting said working tank, means to pivotally mount said tank support for pivotal movement from a first stopped position to a second position, means to counterbalance said working tank about its pivot to retain the tank support in said first stopped position until the material in said working tank reaches a desired level, and means to sense movement of said tank support to said second position.
An apparatus for determing the level of a slurry material in a tank, said apparatus comprising a balance assembly, a tank for holding said nonsolid material mounted on said balance assembly, means to detect shifting of said balance assembly from a first position when the level of material in said tank exceeds a desired amount, and control means responsive to the means to detect to stop transfer of material into said tank when the means to detect has indicated the tank has moved from its first position.
