Disclosed is a method for carrying out a chemical reaction in a reactor, at least one substance is present in a container that is closed in a gas-tight manner, is introduced into the reactor in said container and is released by breaking open the container. The container is designed such that it breaks open when a specified bursting pressure difference between the internal pressure and external pressure is exceeded. The container is broken open and the substance located in the container is thus released as a result of deliberate application in the reactor of a pressure difference exceeding the bursting pressure difference.

A mixing device for bone cement is provided. The mixing device includes a mixing handle, an housing, and a mixing paddle. The mixing handle having a rod, where at least portions of the rod are in tubular form with monomer inside of the rod. The housing has a mixing chamber in which the monomer and a powder are miscible. The mixing paddle is arranged in the mixing chamber and is movable via the rod.

This invention is primarily designed as a low pressure, steady volume supply static mixer manifold for a high pressure pump. A manifold fluid supply is achieved through the use of a centrifugal pump. The design comprises an internal diffuser cylindrical tube inside an external rectangular tube in which static mixing occurs. Capped at one end, the internal diffuser pipe, with flow coming from the opposite side, allows for one flow direction diffused into the outer rectangular tube that then allows for constant bidirectional flow at a constant pressure throughout. while adequately mixing all parts of the fluid makeup. The flow of slurry components between the cylindrical tube and the rectangular tube supports static mixing in part by creating alternating flow pressures between mixing ports (allowing flow of slurry components from the cylindrical tube) and the exit ports based on the different geometries of the cylindrical tube and rectangular tube. The combination of flow and pressure exiting the cylindrical tube through the mixing ports, at an angle to the bottom corners of the outer rectangular tube, creates a natural agitation of the slurry components. The manifold feeds 2 or 5 suction ports into the pump through polls exiting the rectangular outer tube at the top. The pump pulls fluid at intervals much the same way an internal combustion engine fires, in a repeated/patterned order designed to reduce system vibrations. The invention provides consistent pressure and a properly mixed slurry to each suction port. The cutouts in the inner tube are sized and spaced for providing the proper flow, mix, and pressure to each exit port. The cylindrical tube is held in place within the rectangular tube using a standard pipe flange and affixed by any known means to the rectangular tube. This allows for flow 360 degrees within the rectangular tube. As the slurry components flow into the corners of the rectangular tube through the mixing ports on the cylindrical tube, the slurry becomes turbulent but nonetheless creates a constant flow within the mixing chamber between the cylindrical tube and the rectangular tube, and up towards the exit ports leading out of the invention and into the pump. The result of the design is a more consistent slurry, of even pressure and equal flow to all suction ports as the pump pulls the slurry. This allows for a more even wear of the pump parts and less pressure fluctuations between ports. The pump will require less service, and the invention allows the high pressure fluid leaving the main pump to be a much more reliable mix. In the event that the outer or inner tube reaches the end of its effectiveness due to wear, the flanged connectio

An apparatus for promoting a mass transfer reaction having a flow distributor and a drive unit. The flow distributor has a top end surface, a bottom end surface and a peripheral surface that are axisymmetric with respect to a rotation axis. The flow distributor is configured to submerge in a fluid medium and to generate a flow of the fluid medium through at least one of the top end surface and the bottom end surface and through the peripheral surface by rotating around the rotation axis. The drive unit is configured to move the flow distributor perpendicular to the rotation axis.

An additive delivery system may incorporate a cartridge system, including a container cap and a reservoir assembly that provides for storage of an additive. The container cap includes a mixing nozzle for mixing of the additive with a base fluid as the base fluid flows from the base fluid container through the cartridge. A one-way valve prevents backflow of base fluid and/or mixed base fluid/additive from an area downstream of the mixing nozzle such that the base fluid supply remains in a pure state.

A dispenser having a fluid reservoir (R) and a dispenser member (D) mounted on the reservoir (R), the reservoir (R) forming a cylinder (11) and including a piston (2; 2) that slides in the cylinder (11) so as to decrease the working volume of the reservoir (R). The leaktight slide cylinder (11) contains a separator element (3a) that divides the reservoir into two compartments (Ri, Rs), namely a lower compartment (Ri) that is defined between the piston (2; 2) and the separator element (3a), and an upper compartment (Rs) that is defined between the separator element (3a) and the dispenser member (D). The separator element (3a) includes at least one through hole (33) that puts the two compartments (Ri, Rs) into communication with each other, the separator element moving in the leaktight slide cylinder in response to the dispenser member being actuated by pressing on the pusher.

A dry powder and liquid mixing apparatus provides a dry powder container integratable with a liquid container, and a lid engaging both the dry powder container and the liquid container to enable selectable storage and mixing of powder and liquid, such as mixing dry infant formula with water. Through simple manual twisting of the lid about the liquid container to a closed state, a user is able to selectively prevent mixing of stored dry powder and liquid. Likewise, through simple manual twisting of the lid about the liquid container to an opened state, a user is able to selectively enable mixing of the dry powder with the liquid, by shaking the apparatus while the lid is in an opened state, resulting in a consumable mixed formula.

Varied embodiments of a container/dispenser having a multi-chamber bellows member having a plurality of collapsible bellows chambers allowing more than one substance to be contained within the container and simultaneously dispensed when a sufficient axial force is exerted on a platform to compress the bellows member forcing flowable materials from each chamber. In an alternative embodiment, the present invention discloses a retrofit multi-chambered bellows container, which may be adapted to a standard caulking tube container.
