The base plate member bores are opened and closed by nozzle needles which extend through bores disposed in the displaceable piston to a support plate to which the needles are affixed and which is adapted for moving the needles towards and away from the base plate member bores for closing and opening the base plate member bores for regulating distribution of the liquid.

Abstract: A cut-off nozzle for use in dispensing increments of flowable products comprised of a liquid medium in which solids are dispersed, particularly burrito fillings. The cut-off nozzle structure incorporates a light-weight slide member which is shuttled with fast movement between "open" and "close" positions within a chamber having outlet openings in the bottom with which discharge openings in the slide member register or coincide when the slide member is shuttled to its "open" position. The geometry of the chamber-outlet and slide-discharge openings combines with the fast closing action of the slide to provide a sharp positive cut-off of increments of product dispensed from the nozzle with elimination of leakage or drip, plugging and separation of product constituents. The nozzle may be fed with a single stream of product or with two different streams.

Abstract: A mixing and dispensing apparatus for mutually reactive chemicals. The apparatus includes a mixing chamber having a core of inexpensive monolithic design with a reciprocal. The core and purging rod are readily detachable as a unit from the remainder of the apparatus. The purging rod does not perform a valving function, and therefore significant compressive force does not need to be maintained on the mixing chamber core. The apparatus includes separate valves for each of the reactive components remote from the mixing chamber bore which are automatically opened after retraction of the purging rod, so that the chemicals are not maintained under pressure adjacent the purging rod. A visible indication of the amount of useful life remaining for the mixing chamber is also provided.

Abstract: A remote control proportional flow adhesive dispensing gun is pneumatically actuated and electrically controlled. An electric current applied to a magnetic torquemotor rotates a torquemotor arm which displaces the spool of a three-way air valve, admitting air to a control valve stem actuating piston. A constant rate feedback spring directly disposed between the actuating piston and the torque arm of the torquemotor acts to restore the air valve spool to an equilibrium non-flow position as the control valve stem approaches a position proportional to torquemotor control current. The air valve exhausts air from the piston and return springs close the control valve when control signal is removed. A shaped control plug attached to the flow control valve stem varies a control opening linearly as stem position changes.

Abstract: A preferred cleaning system (10) is disclosed which includes a hydraulic timer valve (22) which is in fluid communication with a cleaning chemical dispenser (14) and a water supply (12). The hydraulic timer valve (22) preferably includes a bearing arrangement (44) which is spring biased toward a first end (56) of a timer housing (52). When a water supply valve (20) is opened, water flows into housing (52) to cause the bearing arrangement (44) to move from its first position to a second position.
