The agitator consists of a piston-like agitator disc (4a), which is perforated by channels (4a1), through which the components of the bone cement are caused to flow during the mixing procedure and an agitator rod (4b) resembling a piston rod operatively connected to the agitator disc (4a) and supported in the lid (3) in such a way that it is free to slide. The invention is characterized in that the agitator rod (4b) has an axial channel (4b1), which is closed off at the agitator disc (4a) in such a way that it is capable of being opened.

Abstract: The invention refers to a high-pressure mixing device, for at least two chemical components to be mixed, in particular of the type having a movable mixing chamber, in which the mixing chamber communicates with an outlet duct for discharging the mixture therefrom through a lateral passage and in which the component inlet apertures open directly into the mixing chamber but are oriented so as to face away from the lateral passage in a direction which is opposite to the flow of the mixture in the outlet duct.

Abstract: The invention is drawn to a mixing pump which can transport and effectively mix (homogenize) two or more liquids (or gases) in all ratios between the pure components. The ratio is constant, but is adjustable. This is effected by a double-acting pump cylinder (or two coupled, single-acting cylinders) which produces a charge of the mixture in a two-stroke-cycle. During the 1st stroke liquid (V1) is pumped from one side of the piston (2) through a restriction (12) (pressure drop) into the liquid (V2), while the liquid (V2) is sucked into the cylinder on the other side of the piston. During the 2nd stroke the mixture (V1+V2) is pumped to a storage tank through a restriction (13) (pressure drop), while the liquid (V1) is sucked into the cylinder. By adjusting (by regulator 6), the amount of the liquid (V1) pumped into the liquid (V2), the pump can deliver any ratio of the two components.

Abstract: A mixing head essentially comprises a housing with a mixing chamber which has inlet orifices for the individual plastics components and an outlet orifice for the plastics component mixture. In the mixing chamber is located an expulsion plunger of identical cross-section, which plunger is connected to a working piston which can be actuated by a pressure medium, the plunger being movable to and fro between a mixing position, which leaves the inlet orifices open, and a position in the region of the front outlet orifice, in which it seals the inlet orifices from the mixing chamber. The mixing head moreover has a restrictor which can be pushed into and out of the mixing chamber by a pressure medium.

Abstract: Apparatus for high pressure impingement mixing includes a mixing chamber and aftermixer chamber located on opposite sides of, and perpendicular to, a transfer dispense chamber. Two or more reactive components are injected into the mixing chamber. The resultant mixture is directed across the transfer dispense chamber into the aftermixer chamber, and from the aftermixer chamber back into the transfer dispense chamber and around the crossing mixture to the outlet of the transfer dispense mixer for dispensing. Each chamber includes a plunger which is actuated sequentially to interrupt mixing and clean the respective chamber. The device provides effective and intimate mixing of the reactive components and dispenses a stable emulsion so that the device can be used in applications presently suitable only for low pressure mixing devices. It may also be used in existing high pressure applications but without the need for conventional aftermixer devices and gating systems disposed in the forming molds.
