## Abstract

A process for continuously without pulsation mixing at least two pumpable materials to produce a homogeneous product which is constant throughout the operation. Contents of material suppliers are pumped to a dynamic mixer through a pulsate eliminator where the dynamic mixer is a low pressure mixer and exude leaving the dynamic mixer passes through a multi-way valve and storage container are filled.

## Claims

### Claim 1

A process comprising continuously displacing with pulsating movement created by a force means from at least two material suppliers, pumpable feed material from each material supplier through respective pulsate eliminators into a dynamic mixer having an input end and an exit end wherein the pressure at the input end is less than 3.5 MPa, and thereby continuously combining at least two pumpable feed materials in a predetermined volume ratio to provide a thoroughly mixed product which is being continuously exuded from the exit end of said dynamic mixer at a constant volume flow and said product exiting the dynamic mixer being of constant composition throughout the time the process is operated given the pumpable feed materials are constant and the predetermined volume ratio of pumpable feed materials is constant, continuously passing the mixed product exude from the exit end of the dynamic mixer through a multi-way valve attached to the exit end of the dynamic mixer, and filling storage containers.

### Claim 2 (depends on 1)

The process according to claim 1 in which the multi-way value is a three-way valve and the storage container are sealant cartridges.

### Claim 3 (depends on 2)

The process according to claim 2 in which the three-way value is a butterfly valve.

### Claim 4

A process comprising continuously displacing with pulsating movement created by a pump means from at least one material supplier, a high viscosity material through a first pulsate eliminator into a dynamic mixer having an input end and an exit end wherein the pressure at the input end is less than 3.5 MPa, and continuously displacing with pulsating movement created by a pump means from at least one additive material supplier, a low viscosity material through a second pulsate eliminator into said dynamic mixer through an input port positioned at a point between the input end and the exit end thereby continuously combining the high viscosity material and the low viscosity material to provide a thoroughly mixed product which is being continuously exuded from the exit end of said dynamic mixer at a constant volume flow and said product exiting the dynamic mixer being of one constant composition throughout the process operation, continuously passing the mixed product exude from the exit end of the dynamic mixer through a multi-way valve attached to the exit end of the dynamic mixer, and filling storage containers.

### Claim 5 (depends on 4)

The process according to claim 4 in which the multi-way value is a three-way valve and the storage container are sealant cartridges.

### Claim 6 (depends on 5)

The process according to claim 5 in which the three-way value is a butterfly valve.
