Metadata, the “data about the audio data” that travels along with the multichannel audio bitstream in Dolby Digital, makes life easier for broadcasters while also increasing the creative ability of audio mixers. For broadcasters, audio metadata now means they have a set-and-forget solution, instead of monitoring, compressing, and adjusting levels all over the plant. For audio mixers, this means...

Abstract The article presents the most common varieties of low-volume rotary disc mixers. features their design are described, main advantages and disadvantages identified. A description a new submersible rotor-disk mixer is given. It shown that this type can be used to create high-quality emulsions maintain them. installed in overall tanks reactor.

In this paper, the design requirements of different mixers for direct conversion receivers are discussed. Special attention has been paid into the detection of amplitude-modulated RF signal envelope. Three active mixers have been implemented to investigate the discussed requirements by using a 0.35-μm, 25-GHz BiCMOS technology. The same process allows an objective comparison between the differe...

We report on the continuing development of submillimetre quasi-optical slot antenna SIS mixers, which use two-junction tuning circuits. Direct and heterodyne Fourier transform spectrometer measurements have been performed to compare device performance with predictions. Demonstrated double-sideband receiver noise temperatures of better than 540 K at 808 GHz make these SIS mixers substantially be...

Mixing is a common process in food industry, and in particular it is interesting to develop optimal mixers in order maximize fluid mixing and minimize energy consumption by reducing the viscous dissipation effects. Although many studies and results had been presented in literature for both batch and static mixers (Rauline et al. 2000 and Mutsakis et al. 1986 for a review) the lack of a develope...

With the increasing need for molecular reactions with small liquid volume in biomedical and chemical analyses, miniature mixers have captured considerable attention. Due to the nature of laminar flow in a millimeter-size and blow flow channel, mixing, or the molecular mass transfer in miniature mixers is usually dominated by molecular diffusion. The long diffusion time and mixing distance make ...

This paper describes a new artificial frequency mapping technique suitable for the simulation of RF/Microwave mixers when excited by a multi-tone signal. Due to the computational efficiency gained this way, it is for the first time possible to simultaneously analyse small and large signal behaviour of nonlinear mixers subject to real multi-tone signals. As well as the theoretical study, illustr...

Most systems which require phase information use mixers somewhere in the measurement or comparison of the phase information. Theoretically, any mixer with a dc coupled port could be used as a phase detector. Practically, however, mixers often display some very non-ideal characteristics (e.g., dc offset) when used as phase detectors. The actual mixer chosen for a particular application will ofte...

Ethylene thiourea is manufactured at one factory in the United Kingdom and is mixed into masterbatch rubber at another. Clinical examinations and thyroid function tests were carried out over a period of three years on eight process workers and five mixers and on matched controls. The results show that the exposed mixers, but not exposed process workers, have significantly lower levels of total ...

Static mixers, devices used for mixing immiscible liquids in a compact configuration, were found to be effective in carrying out initial transesterification reactions of canola oil and methanol. The objective of this study was to explore the possibilities of using static mixers as a continuous-flow reactor for biodiesel production. Biodiesel (canola methyl ester) was produced under varying cond...
