Abstract: A vacuum control system is disclosed consisting of a pedal actuated valve connected between a source of air under pressure and a Venturi tube where the valve and the Venturi tube are enclosed within a base and a treadle member pivotally mounted on the base for actuating the valve. The Venturi tube has a port in which a vacuum is created upon actuation of the valve to its open position. Air ejected from the Venturi may be noiselessly diffused by porous filler material disposed adjacent the output side of the Venturi. Further, the ejected air is directed away from the foot and leg of the operator by enlarging the clearance between the forward edges of the treadle member and base while decreasing the clearance between the rear edges thereof when the treadle member is depressed to actuate the system.

Abstract: Draft beer monitoring apparatus in which the amount of beer dispensed is indicated in terms of the sales price, the indicator being controlled by a pair of pulsers operating at different rates associated with the dispensing of a glass or a pitcher of beer. The glass-rate pulser is actuated upon the operation of a switch when the dispensing tap is initially opened. If the tap remains open for a period of time greater than that required to fill a glass, a timer automatically actuates the pitcher-rate pulser instead of the glass-rate pulser.

Abstract: A fushed eyeletting machine which constitutes an improvement over the structure disclosed by U.S. Pat. No. 3,739,141, the improvement features being in the upper setting tool mount structure.The upper arm of the C-shaped frame terminates in a pair of spaced apart tool support fingers, and a double stop toggle mechanism is mounted between the fingers, joined to a mandrel portion of the upper tool at a location thereon between the fingers.The electrical connection to the upper tool is adjacent the tool top and above the fingers.
