An extruder includes a receptacle for containing material to be extruded. The extruder further includes a dispersion blade positioned within the receptacle and a nozzle secured to the receptacle. The nozzle defines a first opening positioned within an interior of the receptacle, defines a second opening positioned outside of the receptacle and defines a channel which extends from the first opening through the nozzle to the second opening defining a flow path which extends from the first opening, through the channel and to the second opening. The nozzle extends through a wall of the receptacle and into the interior of the receptacle such that the first opening is positioned spaced apart from the wall.

One aspect relates to a device for producing a bone cement paste from a monomer liquid and a cement powder as parent components of the bone cement paste and for delivering the mixed bone cement paste, the device having a cartridge having a cylindrical interior. The interior of the cartridge is closed on the front side except for a delivery opening for expelling the bone cement paste. A delivery plunger is arranged in the interior of the cartridge. The cement powder is arranged in the interior of the cartridge. A closure is arranged on the front side of the delivery plunger. The closure closes the delivery opening when the delivery plunger is pressed against the front side of the interior of the cartridge. The closure blocks a further movement of the delivery plunger so that the delivery plunger is spaced from the front side of the interior of the cartridge at least in some areas and a dead volume remains in the interior of the cartridge when the delivery plunger is pressed against the front side of the interior of the cartridge.

An automated computer-controlled sampling system and related methods for collecting, processing, and analyzing agricultural samples for various chemical properties such as plant available nutrients. The sampling system allows multiple samples to be processed and analyzed for different analytes or chemical properties in a simultaneous concurrent or semi-concurrent manner. Advantageously, the system can process soil samples in the “as collected” condition without drying or grinding. The system generally includes a sample preparation sub-system which receives soil samples collected by a probe collection sub-system and produces a slurry (i.e. mixture of soil, vegetation, and/or manure and water), and a chemical analysis sub-system which processes the prepared slurry samples for quantifying multiple analytes and/or chemical properties of the sample. The sample preparation and chemical analysis subsystems can be used to analyze soil, vegetation, and/or manure samples.

Described is a device for granulating a powder to be granulated or a powder mixture to be granulated. The device includes at least one working vessel in which the powder to be granulated or the powder mixture to be granulated is provided, at least one mixer for mixing the powder to be granulated or the powder mixture to be granulated, at least one dosing device for granulating liquid, and at least one drive unit that includes a rotational speed range for providing a drive torque required for the mixer. The drive unit provides a uniformly high drive torque over its entire rotational speed range. Also described is a method for granulating a powder to be granulated or a powder mixture to be granulated using such a device.

A method for producing a coating liquid includes a stirring step of stirring a raw material containing porous particles, a binder resin, and a liquid medium using a planetary mixer. A coating liquid contains porous particles, a binder resin, and a liquid medium, wherein a content of the porous particles is 20% by mass or more. A coating film contains porous particles and a binder resin, wherein a content of the porous particles is 80% by mass or more, and the coating film has a density of 0.4 g/cm.sup.3 or less.

A mixing apparatus (1) for mixing slaughter offal with a preservative agent, the apparatus comprising an offal collection tank (3) with a bottom (4) provided with a discharge opening (5) connectable to a closable discharge, an agitator (8) extending into the offal collection tank, and a pump unit (9) operatively connectable to the discharge, wherein the apparatus further comprises a preservative reservoir (7) mounted on top of the collection tank (3). A collection and preservation system is provided, wherein the addition of preservation agent can be strictly controlled, can easily and quickly be installed and connected when it is to be used. After use, the system is easily removed and cleaned.

A module includes a housing, a sealing feature, a locking feature, and an agitator. The housing has an opening separating inner and outer surfaces and a boss that extends through the housing such that part of the outer surface forms an inner bore of the boss having a terminus pointing toward the opening. The agitator has a base, a shaft, and a mixing element coupled to the base such that the base, in cooperation with the sealing feature, circumferentially seals the opening of the housing to form a cavity defined by the inner surface. The shaft passes through the inner bore. The locking feature when engaged permits independent or simultaneous translational and rotational movement of the shaft while an area between the terminus of the boss and the shaft remains mechanically sealed during the movement against liquid or powder encroachment into a clean area of the inner bore.

A slurry mixing device includes an installation frame, a slurry mixing tank, a slurry feeding tank, a cooling mechanism and a slurry discharging mechanism. The slurry feeding tank is movably arranged under the slurry mixing tank, the cooling mechanism and the slurry discharging mechanism. A mass scale is arranged under the slurry feeding tank. A stirring cavity is formed in the slurry mixing tank, and a stirring paddle is arranged in the stirring cavity. A stirring motor is arranged on the slurry mixing tank. An outlet is arranged on the bottom of the stirring cavity. An oil bath cavity is formed between the slurry mixing tank and the stirring cavity. The cooling mechanism includes a lifting cylinder and a lifting base. The lifting base is provided with a rotating paddle and a rotating motor. The lifting cylinder is arranged on the installation frame.

A system for preparing a polymeric mixture includes: a containment device configured to distribute dry polymeric materials; a receiving chamber in fluid communication with the containment device; a wetting bowl; a dispersing channel; and a mixing chamber connected to the dispersing channel. A method of preparing a polymeric mixture includes distributing water and dry polymeric materials through the various components of the system and mixing the materials with the mechanical mixing device.

An electrical control system for slurry mixing includes a processing module, an input module, a display module and an inspection module. The input module is configured to input the configuration information and send an action command and the configuration information to the processing module. The inspection module is configured to obtain the status information and send the status information to the processing module. The processing module is configured to receive the configuration information and the action command from the input module and the status information from the inspection module, form a production action according to the configuration information or the action command, and then send the configuration information, the action information and the status information to the display module. The display module is configured to receive the configuration information, the action information and the status information, and display the configuration information, the action information and the status information.
