Abstract: One or more techniques and/or systems are disclosed for a way to dispense a variety of liquids, such as paint tinting liquids, while mitigating some problems associated with such systems. A system can help to mitigate these issues by adjusting the temperature at the nozzle tip to match dew point temperature conditions of the ambient air. In controlling the nozzle temperature and environment at the nozzle tip, for example, drying and condensation may be mitigated. A nozzle can be coupled with a nozzle block and temperature controller to control the temperature of the nozzle. A variety of sensors can be used to detect environmental conditions, and a system controller can use the sensor readings to adjust the temperature of the temperature controller to match an ambient dew point.

Abstract: A system for detecting the level of a fluid in a dispensing container may comprise a pressure sensor comprising a detection end disposed inside a dispensing canister. The dispensing canister may have a top and a bottom that is configured to dispense a fluid. The pressure sensor may be operably attached to the canister. The system may further comprise a processing unit comprising a motor control board and a control circuit comprising a processor and programming resident in memory to determine the level at which the fluid is present.

Abstract: A tri-chamber nutating pump is disclosed which includes two pump chambers disposed within a pump housing that accommodates a nutating piston. A reciprocating compensating piston is also provided with its own compensating housing that is connected to the outlet. As a cumulative output from the first two pump chambers reaches its maximum level, the compensating piston is pushed into the outlet or through a passage to reduce the output of the first two chambers and avoid splashing. As the output from the first two chambers reaches its minimum level, the compensating piston is withdrawn from the outlet or through a passage thereby increasing the output of the third chamber to its maximum level when the output from the first two pump chambers reaches its minimum level.

Abstract: An actuator system having a stationary circular array of mechanical devices. The actuator system includes two stationary motors: one motor to rotate the actuator implement around the circular array of mechanical devices until the desired mechanical device is reached; and a second motor to rotate the actuator implement into engagement with an actuator pin of the mechanical device. A nozzle includes a three-sided or U-shaped stationary enclosure, together with a movable gate that completes the enclosure and forms an adjustable size nozzle outlet. As the gate closes after a dispense is complete, a controlled flow of residual liquid exits the nozzle outlet to avoid any additional displacement, thus preventing the undesirable effect of liquid being squeezed out of the nozzle outlet as the gate closes. Conversely, when the gate opens, this sniff back action operates in reverse, thereby filling the nozzle outlet and preventing air from filling the nozzle.

Abstract: A method and apparatus for processing coating compositions. The apparatus comprises: at least one liquid displacement device, such as a stirrer or dispenser pump; a motor for driving the liquid displacement device; a sensor for determining one or more motor performance parameters corresponding to resistance encountered by the motor, such as torque, motor speed or power consumption; and a control unit responsive to output signals from the sensor representing the determined parameter value.

Abstract: An apparatus for making and dispensing frozen aerated products includes a rotating horizontal freeze plate with an upper surface for receiving a chilled aerated mix. The chilled aerated mix includes, in one embodiment, a base that has been sufficiently aerated, and at least one flavor. The horizontal freeze plate rotates about its central axis. The apparatus also includes a spreader body for distributing the chilled aerated mix on the rotating freeze plate. The spreader body extends radially across at least a portion of the upper surface of the freeze plate. The apparatus further includes a scraper for scraping frozen aerated mix off of the rotating freeze plate. The scraper includes a scraper blade with a leading edge that extends radially across the portion of the freeze plate and that engages the upper surface of the freeze plate. The scraper blade is directed opposite the direction of rotation of the freeze plate.

Abstract: An apparatus for selectively dispensing liquids, such as paint colorants. The apparatus comprises container assemblies with a container and a pump. A pump conduit connects the pump to a valve assembly. A recirculation conduit connects the container to the valve assembly bypassing the pump. The valve assembly is configured to be switched between a dispensing position and a recirculation position closing off the dispense conduit. Method of preventing segregation of a multiphase liquid in a pump conduit between a container and a dispense conduit. A valve assembly between the pump conduit and the dispense conduit closes off the dispense conduit while it opens a recirculation conduit between the container and the valve assembly. The liquid is circulated via a circuit formed by the container, the pump conduit, the valve assembly and the recirculation unit.

Abstract: A manually operated seal/closure system for a fluid dispenser manifold is disclosed. The manifold includes at least one nozzle and, more typically, a plurality of nozzles ranging from more than one to twelve or more. The manifold housing includes a sidewall or other stationary structure. The stationary sidewall is pivotally connected to an arm. The sidewall further includes a lateral slot and a curved slot. The arm includes a proximal end pivotally coupled to the sidewall and a distal end coupled to a push plate. The closure system also includes a bracket for supporting a cup and a spring-biased seal. The bracket is coupled to the arm and slidably coupled the sidewall by a pin that extends from the bracket through the lateral slot in the sidewall.

Abstract: A combination dispense and recirculation valve assembly is disclosed for viscous fluids. The assembly easily moves between a dispense and a recirculation position. Therefore, a pump linked to the canister of fluid being dispensed can be run continuously, intermittently or on demand. After the dispense, the actuator moves the valve stem downward to block any further dispense and the pump recirculates fluid upward past an upper valve element and upper valve seat into a recirculation outlet and back into the canister. In the closed position, the valve chamber is sealed to prevent air from causing any remaining colorant to dry. When a dispense is desired, the actuator simply raises the valve stem upward so the upper valve element engages the upper valve seat thereby preventing fluid from being recycled and directing all fluid downward past the lower valve element and out through the nozzle.

Abstract: A fluid dispenser is disclosed for dispensing multiple fluids and that includes valve assemblies with rotary recirculation and dispense valves. A table controlled by a motor and a controller moves all of the valve assemblies to either a dispense position or a recirculation position together. The controller selectively operates the pump motors associated with individual canisters of fluid so that the system can dispense a single fluid or multiple fluids at a time. When in the recirculation position, the fluids can be continuously, intermittently or periodically recirculated to maintain the fluids in a homogenous state.
