A processing apparatus includes a deinking material supply portion that supplies a deinking material to defibrated fibers, and an agitating portion that agitates a mixture of the deinking material and the fibers. The agitating portion includes a chamber and a rotary blade that rotates in the chamber.

Various illustrative systems, devices, and methods of beverage carbonation system flow control are provided. A carbonation system is one example of a treatment system to which the systems, devices, and methods described herein apply. In general, a carbonation system is configured to form a carbonated fluid and dispense the carbonated fluid in a controlled manner. In an illustrative embodiment, the carbonation system is configured to begin dispensing the carbonated fluid with a pressure in a chamber of the carbonation system, in which the carbonated fluid is formed, being above atmospheric pressure. A gas is introduced into the chamber after dispensing has already started via the pressure in the chamber to drive the flow of the carbonated fluid. The gas can be introduced into the chamber according to a predetermined pressure profile.

The present disclosure relates to a pre-5.sup.th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4.sup.th-Generation (4G) communication system such as Long Term Evolution (LTE). A method for operating a terminal in a wireless communication system includes receiving configuration information regarding a random access channel (RACH) from a base station, and transmitting a RACH preamble based on the configuration information. The configuration information includes information indicating the number of RACH transmission occasions in a frequency axis. A terminal includes a processor configured to receive configuration information regarding a RACH from a base station, and transmit a RACH preamble according to the configuration information, wherein the configuration information includes information indicating the number of RACH transmission occasions in a frequency axis.

A mixing method, a controller and a mixing device for mixing components in a mixing vessel are provided. The mixing method includes providing a mixing impeller in the mixing vessel; accelerating the mixing impeller from an inactive state to a rotating state in which the mixing impeller rotates at a first desired speed in a first rotation direction; rotating the mixing impeller at the first desired speed for a first time t.sub.steady,1 in the first rotation direction; changing the rotation direction of the mixing impeller, so that the mixing impeller rotates in a second rotation direction at a second desired speed; and rotating the mixing impeller at the second desired speed for a second time t.sub.steady,2.

A bioreactor system and packaging is provided. The bioreactor system includes a vessel for housing biomaterials for processing and a support structure. The vessel includes a flexible material defining a chamber and a mixing system positioned within the chamber. The mixing system includes an agitator for imparting motion and mixing to the contents of the vessel and includes a base affixed to the flexible material at a base section of the chamber, a shaft moveably mounted in the base and extending from the base into the chamber and at least one mixing element mounted to the shaft, the shaft configured to be driven by a motor magnetically coupled to the shaft and external to the lower portion of the chamber. The support structure is connected to the mixing system such that the shaft is moveable therein and configured to cooperate with an external structure to provide support for the shaft.

Biomass feedstocks (e.g., plant biomass, animal biomass, and municipal waste biomass) are processed to produce useful products, such as fuels. For example, systems are described that can convert feedstock materials to a sugar solution, which can then be fermented to produce a product such as a biofuel.

A modular mixing impeller assembly that includes one or more connection tubes, and one or more impellers configured for assembly to the one or more connection tubes. Each of the one or more impellers has a plurality of mixing blades. Each of the one or more impellers is assembled onto at least one connection tube via a friction fit such that each of the one or more impellers is configured to rotate with its attached connection tube, and wherein the assembly between impeller and connection tube creates an airtight and water-tight seal.

A method for mixing a biological suspension includes disposing a biological suspension within a compartment of a container, the biological suspension comprising cells or microorganisms suspended within a nutrient growth medium; and rotating a first drive line and laterally spaced apart second drive line within the compartment of the container so as to cause the drive lines to twist into a helical configuration and mix the biological suspension.
