Abstract: A quickly adjustable ratchet wrench is essentially a crescent wrench modified by eliminating the adjusting screw and substituting a locking member and a lever to engage and disengage the locking member with the rack on the movable wrench jaw. A tension spring lightly biases the movable jaw toward closed position. With the locking member disengaged from the rack the movable jaw may be manually opened, and when the movable jaw is released the light spring bias closes the jaws on a bolt head. When the wrench jaws are engaged with a bolt head, rotation of the lever arm against a rearward extension that replaces the wrench handle engages the locking member with the rack to turn the bolt, while rotation of the lever arm away from the extension disengages the locking member and permits the jaws to open against the light spring bias and slip over the angles of the bolt head; thus eliminating the need to remove and replace the wrench on the bolt head.

Abstract: A system for computing and displaying quantity and cost of a liquid flowing through a pipe, as gasoline delivered to a consumer. A detector responsive to the passing of a predetermined quantity of the liquid provides a pulse function to money and quantity set circuits. The money and quantity set circuits simultaneously provide signals representative of the units (i.e., gallons) and cost (i.e., dollars) each time a pulse function is received. The signals are accumulated in a memory and the totals are added to subsequently received signals to update the memory each time the predetermined quantity has passed. A nonvolatile totals memory provides a running total of cost and quantity and a sequentially operated display provides a visual display of cost, quantity and totals.
