Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
188 words
A DEVICE FOR DISPENSING INCREMENTAL HEIGHTS OF A LIQUID IN A CONDUCTIVE CONTAINER, INCLUDING A COMBINATION: AN ELECTRICALLY CONDUCTIVE SUPPORT FOR SAID CONDUCTIVE CONTAINER, A DISPENSING DEVICE HAVING A DISPENSING VALVE, A CRADLE FOR SUPPORTING SAID DISPENSING DEVICE AT A POURING ANGLE AND HOLDING IT IN A FIXED POSITION, LEVER MEANS FOR CLOSING SAID VALVE MECHANICALLY, A SOLENOID HAVING A CORE CONNECTED TO SAID LEVER MEANS AND ACTUATING IT FOR CLOSURE OF SAID VALVE UPON ENERGIZATION OF SAID SOLENOID, MEANS FOR CHANGING THE STROKE OF SAID LEVER MEANS TO ACCOMMODATE DIFFERENT SIZES OF DISPENSING DEVICES, A VERTICAL ROD MOVABLE VERTICALLY IN SAID CONTAINER AND SPACED FROM THE WALL THEREOF AND HAVING AT ITS LOWER END A PROBE TIP, MEANS TO MOVE SAID ROD VERTICALLY, HEIGHT-MEASURING MEANS FOR ACCURATELY INDICATING THE AMOUNT OF VERTICAL MOVEMENT OF SAID ROD, MEANS FOR SENDING A VERY SMALL ELECTRICAL POTENTIAL BETWEEN SAID CONTAINER WALL AND SAID PROBE TIP, AND MEANS FOR ENERGIZING SAID SOLENOID UPON ATTAINMENT OF ELECTRICAL CONDUCTANCE THROUGH THIS LIQUID BETWEEN THE WALLS OF THE CONTAINER AND THE PROBE TIP, WHEN SAID LIQUID RISES TO THE LEVEL OF SAID PROBE TIP.
