Publication number: 20080310969Abstract: A dual chamber mixing pump design is disclosed which allows two different sources of fluid to be combined into one mixed product fluid. The pump is divided into two chambers, the proximal chamber and the distal chamber. The chambers are defined in part by a piston having proximal and distal ends and recessed sections. The pump utilizes one common driving mechanism to axially rotate and laterally reciprocate the piston to provide continuous pumping of fluids with reduced pulsations. Each fluid enters through its own pump inlet and outlet. For mixing applications, the outlets are joined together. The flow volume per stroke of each chamber is determined by the lateral stroke of the entire piston assembly and also by the annular areas of the proximal and distal ends of the piston. The flow volume per stroke may be altered by varying the piston and shaft diameters for each chamber. This allows mixing of two fluids in any ratio or proportion desired.Type: ApplicationFiled: August 2, 2007Publication date: December 18, 2008Applicant: FLUID MANAGEMENT OPERATIONS LLCInventor: Tim Patrick Hogan

Publication number: 20070211568Abstract: Disclosed herein is a system and method for adequately securing the currently available metal and plastic containers for paint and other fluids as well as other foreseeable containers in an automated fashion without crushing or damaging the containers, without using any special adapters for particular container types and without operator intervention. To avoid crushing a plastic container, the disclosed system and method takes advantage of the compressibility of these less rigid plastic containers. It has been found that a plastic paint container can be safely clamped in place without structural damage if the clamp plate travel after engagement with the top of the container is limited to a certain value, for example, about 5/16?. When the compression amount if limited or controlled, the plastic container will not move or will move very little during a three minute violent shake cycle. Some conventional containers are not readily compressible, such a metal cans, drums or the larger (five gal.Type: ApplicationFiled: March 9, 2006Publication date: September 13, 2007Applicant: Fluid Management Operations, LLCInventors: Margaret Lowan, Steven Page

Publication number: 20070211567Abstract: A clamping mechanism and method are disclosed for a mixing machine that detects when the upper clamping member engages the tops or lids of the containers loaded into the mixing machine. The disclosed clamping mechanism includes a lower base and an upper plate defining an adjustable clamping distance disposed therebetween. At least one of the lower base and upper plate is moveable to increase or decrease the clamping distance. The upper plate is pivotally connected to a cross member so the upper plate is at least partially pivoted away from the cross member when nothing is clamped between the upper plate and lower base. At least one of the cross member and upper plate is associated with a sensor. The sensor is linked to a controller, which controls the movement of the upper plate or the lower base (or both) for clamping and unclamping articles disposed on the lower base.Type: ApplicationFiled: March 9, 2006Publication date: September 13, 2007Applicant: Fluid Management Operations, LLCInventor: William Miller

Publication number: 20070196223Abstract: A nutating pump is disclosed which has a modified piston and housing or casing that provides two distinct pump chambers or areas. Output from the first pump chamber is delivered during a first half of the dispense cycle or the piston movement cycle. A substantial portion of this output is held for delivery by the second chamber during a second part or half of the dispense cycle. Thus, the output generated by the pump is not altered or reduced, it is delivered over the entire piston movement cycle as opposed to prior art pumps which deliver all of the fluid during a first half or first portion of the piston movement cycle. In this way, superior pulse modification is achieved as fluid is delivered across the entire piston movement cycle as opposed to a first half or first portion of the piston movement cycle. In additional embodiments disclosed, two distinct chambers are also provided but each chamber generates its own output as the piston includes two machined or flat sections for active pumping.Type: ApplicationFiled: February 22, 2006Publication date: August 23, 2007Applicant: Fluid Management Operations, LLCInventor: Tim Hogan

Publication number: 20070084520Abstract: An improved dispensing system and dispensing routine for multiple ingredient formulas is disclosed. The system includes a controller linked to an actuator, a scale and, a means for imparting movement to a plurality of pumps or conveyors and containers for dispensing the plurality of ingredients. After a formula is selected, the controller acts to at least partially load the pump with the first of said ingredients, reads the scale to account for the weight of the receptacle, calculates the motion of the pump required to dispense the target amount of said first ingredient, and either executes a percentage or portion of the motion of the pump required to dispense the target amount of said first ingredient, leaving a remaining amount or a safety factor in the form of a previously determined <maximum overshoot> value. Both techniques avoid an over-dispense which would require the batch to be rejected.Type: ApplicationFiled: October 13, 2005Publication date: April 19, 2007Applicant: FLUID MANAGEMENT OPERATIONS LLCInventors: Martinus Driessen, Ronald Krom

Publication number: 20060086405Abstract: A combination gravimetric and volumetric fluid dispenser is disclosed which includes a scale linked to a controller. The controller is linked to a plurality of two stage valves which control the dispensing of large quantities of base materials. The controller is also linked to a plurality of nutating pumps which together with the controller controls the dispensing of smaller quantities of additive materials. The dispensing system disclosed is particularly useful for paints or other liquid formulations where larger quantities of base materials are added and which can be added by weight and whereby precise measurements of the larger base materials is not particularly required. However, the incorporation of nutating pumps and the addition of smaller amounts of additives by volume using the nutating pumps enables precise dispensing of the additives, such as colorants for paint. The larger containers or reservoirs of base material may be disposed at a remote location from the dispensing apparatus.Type: ApplicationFiled: December 8, 2005Publication date: April 27, 2006Applicant: FLUID MANAGEMENT OPERATIONS LLCInventors: Kenneth Kaufhold, Steven Page, Donald Rummelhart
