A storage and mixing device for two-component polymethyl methacrylate bone cements having a cylindrical interior of a cartridge that is delimited on a front side by a cartridge head, a plunger arranged to be axially movable in the cylindrical interior of the cartridge and spaced from the cartridge head, a powdery first parent component of the bone cement, that is contained in the interior between the plunger and the cartridge head, a feed-through arranged in the cartridge head or in the cylinder barrel of the cartridge between the plunger and the cartridge head. The feed-through is connectable to a fluid line, a receptacle for a monomer liquid, wherein the fluid line connects the feed-through to the receptacle in a liquid-permeable manner, and a press-out device pushable into the receptacle, so that monomer liquid is pressable out of the receptacle into the fluid line. The plunger (2) is spaced from a back side of the cylindrical interior, located opposite the front side, so that, by moving the plunger in the direction of the back side, the press-out device is pushable into the receptacle and a reduced pressure is producible in the interior of the cartridge between the plunger and the cartridge head.

A storage and mixing device for PMMA bone cements having a cylindrical interior of the cartridge that is delimited on a front side by a cartridge head with a closed delivery opening, a plunger which is arranged to be axially movable in the cylindrical interior of the cartridge and which is spaced from the cartridge head. The plunger circumferentially rests against the inner wall of the interior, so that the plunger divides the interior of the cartridge into two sections in a gas-tight manner, a powdery first parent component of the bone cement, which is contained in the interior between the plunger and the cartridge head, a feed-through which is arranged in the cartridge head or in the cylinder barrel of the cartridge between the plunger and the cartridge head, wherein the feed-through is connected to a fluid line in which a monomer liquid as a second parent component of the bone cement is contained or into which a monomer liquid is fillable or introducible. A filter is arrangeable in the cartridge head, in the feed-through and/or in the fluid line, wherein the filter is permeable to the monomer liquid and impermeable to the first parent component, wherein the plunger is spaced from a back side of the cylindrical interior, located opposite the front side, to an extent that, by moving the plunger in the direction of the back side, a reduced pressure is producible in the interior of the cartridge between the plunger and the cartridge head, wherein the reduced pressure is able to suck the monomer liquid out of the fluid line into the interior of the cartridge.

A volatiles consuming eductor system for coated scrap metal furnaces with separate delacquering and melt chambers. Motive gas is forced through an inlet into a mixing chamber in a direction opposite a suction port, creating a Venturi that draws gases from the delaquering chamber through the mixing chamber. The motive gas and the drawn gases mix and are forced through a discharge port, ignited, and injected into the melt chamber to help heat the melt chamber. A computer monitors process conditions and controls a regulator that adjusts the motive gas flow in response to those conditions.

A device mixes bone cement and stores parent components of the bone cement. The device has a cartridge comprising an interior, that is closed on one side by a movable delivery plunger, a receptacle comprising side walls for receiving a monomer liquid container that are closed at least in some regions. The receptacle has at least one deformable closed side wall, a screen and/or a filter arranged below the receptacle so that the contents of the opened monomer liquid container flow through the screen and/or the filter. The device further has a connecting line through which the monomer liquid is to be routed into the interior of the cartridge, a hollow cylinder which is connected to the connecting line and which is connected to the receptacle by way of a fluid connection so that the hollow cylinder is arranged in a fluid line between the receptacle and the interior of the cartridge. A pump plunger is arranged in the hollow cylinder, which is axially displaceable in the hollow cylinder, and an opening device, which is movably mounted against the deformable side wall of the receptacle. The opening device extends into the hollow cylinder, wherein, by pressing the pump plunger into the hollow cylinder, the opening device is to be pressed against the deformable side wall of the receptacle so that the deformable side wall deforms such that a monomer liquid container located in the receptacle is to be opened by the pressure of the opening device.
