A dispensing system includes a device having a body extending along a longitudinal axis between opposite proximal and distal ends. The body includes a proximal chamber, a distal chamber and a wall between the chambers. The body includes a first port in communication with the proximal chamber and a second port in communication with the distal chamber. A shaft is movably positioned within the body. The shaft extending through the wall and comprising a proximal plunger positioned within the proximal chamber and a distal plunger positioned within the distal chamber. Wherein pressure introduced through an opening in the proximal end moves the shaft such that the proximal plunger moves a material within the proximal chamber out of the first port and the distal plunger moves a material within the distal chamber out of the second port. Kits and methods of use are disclosed.

A device for creating reactive oxygen and reactive nitrogen species comprising: a plasma generator comprising at least one electrode positioned within an open-ended chamber and a centrifugal mixing chamber in fluid communication with the plasma generator, said centrifugal mixing chamber comprising a mixing chamber side wall and a blade, said blade oriented to allow passage of air in a circular motion around a central post of said centrifugal mixing chamber, and an exit nozzle on an opposing end of said centrifugal mixing chamber.

A micro-bubble generator is provided between an input end and an output end of a water outlet device. The micro-bubble generator includes a water inlet member and a water outlet member. A gas inlet gap is remained between the water inlet member and the water outlet member, with the gas inlet gap being communicated to external air, such that the external air is allowed to enter the micro-bubble generator for gas-liquid mixing and generate minute and dense bubbles.

A segmented, heated urea mixer and an exhaust system to control NOx emission from combustion engines comprising a plurality of elements, at least one mixing element independently heatable by an external power source to a temperature above a temperature of another element. A method of using the exhaust gas mixer and an exhaust gas mixer system further comprising a controller is also disclosed.

A variegator and a process for using it. The variegator permits the manufacturer to obtain desirable patterns of distribution of sauce and chunks in frozen confections while at the same time permitting fast cleaning-in-place times to minimize factory downtime. The variegator comprises a) one or more conduits, each suitable for feeding a base frozen confection to a first opening or set of openings into a chamber, b) one or more conduits suitable for feeding a fluid variegating material such as a sauce through a second openings or set of openings at a level below the first set into the chamber below the base frozen confection opening, and c) a static mixer below the variegating material opening, the static mixer comprising at least two baffles.

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 static mixer is disclosed. The static mixer comprises a housing (22) defining an internal mixing cavity (36) that longitudinally extends along a central axis between an inlet (38) and an outlet (40) and is adapted for axial flow of a fluid therethrough. The static mixer also comprises a mixing element (42) disposed within the mixing cavity (36). The mixing element (42) is configured to be free from an impingement surface oriented substantially perpendicular to a main direction of fluid flow through the internal mixing cavity (36). The mixing element (42) comprises an elongated mixing blade that is oriented longitudinally within the mixing cavity (36) and comprises a nose axially oriented toward the inlet (38). The static mixer may comprise a heat-exchanging jacket integrally formed with the housing (22). An additive manufacturing system comprising the static mixer, and methods of making and using the same, are also disclosed.

A mixer including a first inlet channel, a second inlet channel, and a first dividing wall positioned between the first inlet channel and the second inlet channel. The first dividing wall radially extending from a centerline. The first inlet channel directs material away from the centerline and the second inlet channel directs material toward the centerline.

A gas mixer (100), to which a first gas and a second gas are fed, mixes the two fed gases to form a gas mixture. A helical component (2) is arranged in an interior of an outer component (5). A helical mixing cavity (20) is formed between the outer component and the helical component (2). An additional mixing volume (6) is located in the interior of the outer component (5) or in the interior of the helical component (2). One gas is sent through a first feed line (31) to the helical mixing cavity (20), and the other gas is sent through a second feed line (32) to the additional mixing cavity (6). A gas mixture discharge line (40) discharges the produced gas mixture from the helical mixing cavity (20).
