Presented and described herein is a stroke system (1) for dosing a fluid from a container (3), comprising a piston pump (5) with a piston (7), so that a fluid can be dosed from a container (3) by displacement of the piston (7), and a temperature control device (29) for controlling the temperature of the fluid to be dosed by means of the stroke system (1).

Mixing systems and methods that include a mixer housing and one or more disk assemblies for mixing and processing materials is disclosed. The disks rotate to mix an additive into the material and to carry agglomerated solids toward a discharge of the mixing system. The disks may have a plurality of fingers or lobes which extend from a central portion of the disks.

A toilet apparatus has a waste material receiving bowl with an opening at a top of the waste material receiving bowl. A bag receives and retains waste material and an absorbent media introduced through the opening. An agitation device agitate the absorbent media and the waste material at a lower portion of the bag to cause the absorbent media to at least substantially cover the waste material while the agitation device is not contacting the absorbent media and the waste material.

A toilet apparatus includes a waste material receiving bowl having a top member with an opening defining an annular seating surface, and an agitation device to agitate an absorbent media and the waste material disposed in the disposable bag while the agitation device does not come into contact with the absorbent media and the waste material. The toilet apparatus also includes a disposable bag having an upper edge to be releasably secured to the annular seating surface such that waste material introduced through the opening is received by and retained in the bag.

Static plant for preparing feed mixes for ruminant livestock, having a conveyor unit for conveying the feed mix ingredients, chain and/or screw feeders, feeders with weight sensors and supplementary conveyor belt, silos of solid ingredients, and silos of liquid ingredients, independently supplying two or more high-capacity mixers, via the conveyor unit by a dual flow, the mixers including weight control means, laser sensors and strain gauges. The invention allows for mixing to be controlled with increased accuracy and, consequently, improving the quality of the mix, using fully automated continuous operating cycles, the resulting mix being discharged onto any type of known device using discharging means, for its distribution.

An extruder is disclosed, and more particularly, to an integrated single screw extruder and a twin screw extruder for mixing, compounding, kneading and/or extruding of materials. The integrated extruder includes a first barrel assembly and a second barrel assembly. The integrated extruder further includes a first screw having a first threaded portion and a second threaded portion. The first threaded portion is housed within the first barrel assembly and is configured to provide upstream material processing. The second threaded portion is housed within the second barrel assembly and is configured to provide downstream material processing. The integrated extruder further includes a second screw having a non-threaded shaft portion and a threaded portion. The threaded portion of the second screw is housed within the second barrel assembly and is configured to provide the downstream material processing with the second threaded portion of the first screw.

A method of retrofitting an existing apparatus for forming concrete products, where the apparatus comprises an existing component located upstream of a product mold and adapted to deliver treated concrete to the product mold, adapts the existing component to treat fresh concrete to be delivered to the product mold by a new component with treated water infused with a concentration of carbon dioxide nanobubbles. The step of adapting comprises adding to the existing component a water delivery system that is configured to direct the treated water into the fresh concrete, where the water delivery system is provided with one or more liquid manifolds configured to dispense the treated water into the fresh concrete to form treated concrete.

An apparatus for delivering a wet concrete mix to a product mold, where the apparatus comprises a hopper configured to retain a fresh concrete mix, a source of treated water having a concentration of nanobubbles of a gas at least double a natural concentration of nanobubbles of the gas within a natural state of the water, a water transport coupling the source of treated water with the hopper, a valve interposed within the water transport for selectively releasing the treated water into the hopper, and a mixer in communication with the hopper for mixing the treated water with the fresh concrete mix to yield an infused wet concrete.

An extruder is disclosed, and more particularly, to an integrated single screw extruder and a twin screw extruder for mixing, compounding, kneading and/or extruding of materials. The integrated extruder includes a first barrel assembly and a second barrel assembly. The integrated extruder further includes a first screw having a first threaded portion and a second threaded portion. The first threaded portion is housed within the first barrel assembly and is configured to provide upstream material processing. The second threaded portion is housed within the second barrel assembly and is configured to provide downstream material processing. The integrated extruder further includes a second screw having a non-threaded shaft portion and a threaded portion. The threaded portion of the second screw is housed within the second barrel assembly and is configured to provide the downstream material processing with the second threaded portion of the first screw.

The present invention relates to an apparatus, which can be part of a pre-treatment system in a plant for the production of fuels, e. g. bio-ethanol, derived from plant biomass, e. g. first generation crops, such as grain, sugarcane and corn or second generation crops such as lignocellulosic biomass. The invention relates to an apparatus for processing, such as fluffing and mixing, at least two media, such as a solid, e. g. biomass, and a fluid, e. g. steam, so as to rendering the first medium susceptible to efficient receiving of energy and/or mass which is provided by localized release of the second medium. Although the description of the present invention focuses on biomass, it is envisaged that the invention is generally applicable to control the mixing of at least two media by crossing their stream of while dispersing at least one of them.
