A closure mechanism for a wine storage container having two fluid channels provides a compressive structure to apply a compressive force to a delayed valve actuation mechanism having an actuation plate, a support plate, and a valve plate. The actuation plate may be partially rotated before beginning to open or close the fluid openings. The first fluid channel permits wine to flow from the lower portion of the storage container, through an aerator, and through a valve cap assembly. The second fluid channel permits air to flow into the valve cap assembly to the aerator, and to vent the container. The valve cap assembly includes a decorative cap with a liquid outlet port positioned 180 degrees from a vent inlet port. In a fully open orientation, the liquid outlet port is positioned over the first fluid channel, and the vent inlet port is positioned over the second fluid channel.

A stuffing screw (2) for use in an extruder system comprises a housing (7) and at least one conveying screw (5), which is mounted in a rotatable manner within the housing (7), wherein a conveying space is formed between an inner side of the housing (7) and the conveying screw (5). The stuffing screw (2) is characterized in that at least one portion of the inner side of the housing (7) is provided with one or more depressions, in particular in the form of a groove (13).

A system for bone cement includes a vial holder configured for receiving a vial and including a holding structure for maintaining the vial in the vial holder. The vial includes a monomer component for bone cement. A holder chamber is configured to receive and secure the vial holder. The vial holder is advanced toward a vial-breaking device for breaking the vial and releasing its contents into the holder chamber past the elastomeric seal. Once the vial holder is advanced further the elastomeric seal is deformed to form a seal and prevent fumes produced from escaping from the device.

A high efficiency cooling wine aerator comprises a tannin balancing piece, a wine aerator body, an ice kettle, an aeration nozzle and a bracket. A cooling cavity is arranged in the wine aerator body; the upper end of the wine aerator body is provided with an opening led to the cooling cavity; the bottom end of the cooling cavity forms a shrinking mouth; the lower end of the wine aerator body is provided with a first connector; the first connector is provided with an aeration cavity led to the shrinking mouth; the lower end of the first connector is provided with a plurality of air inlet grooves at intervals; the tannin balancing piece is detachably connected to the opening at the upper end of the wine aerator body; the ice kettle is placed in the cooling cavity; the aeration nozzle comprises an aeration nozzle body and a second connector arranged above the aeration nozzle body; the aeration nozzle is detachably connected below the wine aerator body through the second connector; and the bracket comprises a supporting seat and a plurality of supporting feet arranged at the circumferential side of the supporting seat at intervals. The high efficiency cooling wine aerator of the present invention is detachable, convenient in cleaning, coolable during decanting and small in noise during decanting.

A system for mixing acid and water can include a tank for holding acid, an acid pump for pumping acid out of the tank, an acid flow meter, an acid control valve, a water pump for pumping water, a water flow meter, a water control valve, a flush valve to selectively flush the system with water, and a controller to monitor the flow meters and control the pumps and the valves. The acid control valve and/or the water control valve can be an electronically controlled valve. The flush valve can be an electronically controlled valve to selectively permit water to flow from downstream of the water pump to upstream of the acid pump. The acid control valve, the water control valve, the flush valve, or any combination thereof can be throttled by the controller to control flow therethrough.

The present application provides a method and a system for recycling a polymer. The method includes introducing polymer into a primary melting extruder, producing a polymer melt that is combined with a fluid oil to at least partially dissolve the polymer melt. A secondary mixing extruder mixes these to form a polymer solution that is introduced into a refinery oil stream, producing a polymer-comprising oil stream, which is fed into a refinery process unit. The system includes a primary melting extruder for forming a polymer melt from polymer. A secondary mixing extruder receives the polymer melt. One or more hydrocarbon inflow conduits for providing a fluid oil to the primary melting extruder and/or the secondary mixing extruder are configured to form a polymer solution from the fluid oil and the polymer melt. There is a feed system outlet for feeding the polymer solution to a refinery oil stream.

Methods for the production of foamed sclerosant compositions are provided. Containers include a container body including one or more sidewalls extending between a top and a bottom of the container body and a bottom surface, a foaming space being defined in an interior of the container body. The foaming space contains a sterile gas and a mixing element configured to be operatively coupled with a rotatable actuator without the actuator entering into the foaming space. The container includes a female coupling member for mating with a syringe, and a pressure equalizer for equalizing a pressure inside the foaming space with a pressure outside the foaming space. Systems and kits including such containers are also provided. Also disclosed are methods for the preparation of a sclerosant foam which may include a pressure release before extraction of the foam and/or a continued rotation of the actuator while the foam is being extracted.

A blending machine, for homogenizing materials deposited within an intermediate bulk container (IBC), includes: a frame; a drive motor; a clamp disk rotatably supported by the frame and coupled to the drive motor to drive disk rotation; first and second jaw clamps movably mounted to the frame; and a drive mechanism to drive the jaw clamps to translate toward each other and rotatably secure the IBC's boom to the rotatable clamp disk. A clutch, a torque limiter, and a limit switch limit the pressure applied by the clamps, and the extent of their travel to optimize clamping and rotatability. The blending machine is moveably mounted to a pedestal, and elevated by an actuator. A blending bar within the IBC is coupled through the boom to the clamp disk, and driven to rotate to blend the materials, in addition to mixing by rotation of the ICB.

Syringe for dispensing foam having a syringe barrel, a nozzle and a bore to receive a syringe plunger having a front end and a back end. The syringe plunger includes at the front end thereof a waste container defined by a cylindrical side wall, a front end wall and a rear end wall, the walls being arranged such that an external cylindrical surface of the walls forms a seal with an internal surface of the syringe barrel. The waste container has an inlet aperture in the front end wall which is in communication with the syringe nozzle when the plunger is fully depressed into the syringe barrel. The waste container further has a hydrophobic vent in the rear end wall thereof which allows air to escape from the waste container while substantially preventing foam from escaping the waste container when the syringe is in use.
