Provided is a stirring device including: a stirred tank, of which an inner peripheral wall has a circular shape in cross section; and at least one flow impeller and at least one shearing impeller that are located inside the stirred tank and configured to be rotatable independently of each other, in which rotational centers of the flow impeller and the shearing impeller are coaxially provided, the flow impeller rotates around a vertical axis along the inner peripheral wall of the stirred tank to form at least a flow directed toward a lower side in the stirring object existing in the stirred tank, and the shearing impeller imparts a shearing force to the stirring object and is provided on a radially inward side of the flow impeller in the stirred tank and at a position contacting the flow of the stirring object formed by the flow impeller.

System and method for dispensing a flowable product are provided. The system includes a mixing chamber having a first inlet, a second inlet and an outlet. The mixing chamber of the system contains a mixing element capable of motion. The system also includes a paste located in an enclosure configured to flow into the mixing chamber via a first channel connected to the first inlet, and a flowable medium configured to flow into the mixing chamber via a second channel connected to the second inlet. The mixing chamber is configured to mix the paste and the flowable medium using the mixing element, thus, producing the flowable product that may be output via the outlet.

Storage and mixing systems for pasty two-component polymethyl methacrylate bone cements comprise a tubular cartridge having a cylindrical inner chamber, a cartridge head, which closes one end of the tubular cartridge at the front side, a partition that is disposed axially in the cylindrical inner chamber of the cartridge. The partition divides the cylindrical inner chamber of the cartridge bounded by the cartridge head into two cavities that are spatially separated from one another, wherein a first pasty cement component is present in the first cavity and a second pasty cement component is present in the separate second cavity. The systems further comprising two dispensing plungers axially displaceable in the two cavities of the cartridge, wherein the dispensing plungers close the two cavities on the back side of the cavities situated opposite the cartridge head, a bending device for deforming the partition, wherein the bending device is axially movable in the cartridge and is disposed, or is to be disposed, behind the dispensing plungers, as seen from the cartridge head, wherein the bending device has a deflection surface that is inclined with respect to the axis of the cartridge and pushes the partition laterally in the direction of the inside wall of the cartridge when the bending device is pushed into the cartridge.

A delivery system is provided that includes a device having a body extending along a longitudinal axis between proximal and distal ends. The body includes a proximal chamber, a distal chamber and a wall between the chambers. The body includes a first port in communication with the proximal chamber and a second port in communication with the distal chamber. A shaft is movably positioned within the body. The shaft extends through the wall and includes a proximal plunger positioned within the proximal chamber and a distal plunger positioned within the distal chamber. Pressure introduced through an opening in the proximal end moves the shaft such that the proximal plunger moves a fluid within the proximal chamber out of the first port and the distal plunger moves a fluid within the distal chamber out of the second port to simultaneously actuate a bone filler dispenser. Systems and methods are also provided.

A mixing inset for a static mixer comprises a plurality of mixing elements which are interconnected by at least one peripheral web wherein the peripheral web is at least partly discontinuous. A static mixer for mixing together at least two components comprises a mixer housing, a mixing inset being arranged at least partly in the mixer housing, The mixing inset further comprises a plurality of mixing elements which are connected by at least one peripheral web which is at least partly discontinuous. A kit of parts comprising a static mixer, a two component cartridge suitable for connecting to said static mixer and for dispensing the two components through said static mixer and mixing said components thereby and optionally a dispensing gun.

A process and associated system for creating color effects using extrudable material, such as plastic and metal for example, are presented. Flows of first and second viscous materials of respective colors are provided and then combined in a predetermined pattern to form a stream of combined viscous material. A dynamic mixer is the then used to apply a predetermined dividing, overturning and combining motion to the stream of combined viscous material to partially mix the first viscous material and the second viscous material, such that upon exiting the dynamic mixer, the first material of the first color and the second material of the second color form a color pattern in the stream of combined viscous material. The dynamic mixer has elements configured for acquiring a specific radial orientation in a range of radial orientations that may be varied during the application of the dividing, overturning and combining motion to the stream of combined viscous material to cause variations in the color pattern in the stream of combined viscous material. Sheets of extruded material may be created using such process and system and used in the manufacturing of many different products including, but not limited to, kayaks, stand-up paddle boards, garden furniture and many others. In some embodiments, the sheets may be characterized by color bands extending diagonally with reference to a longitudinal extent of the sheet.
