Hielscher ultrasonic reactors are used in many industries to assist and improve the catalytic extraction processing (CEP) or so-called phase-transfer extraction (PTE). Catalytic extraction involves a heterogenous immiscible phase system, such as liquid-liquid or liquid-solid. Ultrasonic high-shear and cavitational forces improve the dissolving rates of solutes significantly, leading to a faster and more complete extraction.
In today’s automotive marketplace, design has become the key competitive advantage for many manufacturers and suppliers. For these companies, top business initiatives include streamlining the conceptual design process, increasing the number of iterations, developing desirable designs and building brand equity. Global brands, global design and rapidly shifting market trends are contributing to a change in automotive styling. Designs must resonate with many different customers and raise ...
Induction is a process by which a magnetised or electrically charged object produces magnetism, an electric charge or an electro-motive force, in another object without being in contact with it. These processes are called magnetic induction when magnetism is produced, electrostatic induction when an electric charge is produced and electromagnetic induction when an electric voltage is produced. This article from Gill Research & Development discusses each of these.
It takes many activities and skills to bring the ideas and designs of architects/engineers to fruition. In this white paper, Man and Machine discusses building information modelling (BIM) — which attempts to standardise the creation and exchange of information to make the design, construction and operational management of a facility or infrastructure asset more efficient.
Today’s successful automotive manufacturers and OEMs must design innovative, alluring vehicles — and bring them to market faster than their competitors. To drive consumer interest, they need to develop interiors and exteriors that are perfectly smooth, pleasing to the eye and pleasant to the touch. Leading automotive companies rely on Autodesk Alias Surface for technical surfacing tools to create these high-quality, accurate and precise surfaces.
This video explains the causes of linear regulators’ dynamic limitations and presents board-level techniques for measuring and improving ripple and spike rejection.
The sonication of coal slurries contributes to various processes during the energy production from coal. Ultrasound promotes the catalytic hydrogenation during the liquefaction of coal. Furthermore, sonication can improve the surface area and extractability of coal. Undesired chemical side reactions during the de-ashing and desulphurisation can be avoided — accomplishing the process in much less time.
In the third instalment of its ‘Looking Ahead’ series about future manufacturing challenges driven by technological, demographic and environmental changes, toolmaker Sandvik Coromant explores the ramifications that keeping pace with — or falling behind — the coming technology shifts will have on the success of businesses. According to Sandvik Coromant’s white paper ‘Manufacturing Intelligence’ and its video ‘Looking Ahead’, we are now on the verge of the fourth industrial revolution, ...
Surtech — a specialist in the manufacture, design and distribution of mechanical surface finishing equipment and materials — has released a short guide to sheet metal deburring equipment.
There are many ways to measure the flow of liquids and gases. One of the newer technologies is ultrasonics, which is becoming more widespread in flowmeters. What benefits have encouraged the uptake in ultrasonics? This article from Gill Research and Development discusses the two principles for ultrasonic flow measurement: the Doppler effect and time of flight. The article also presents the benefits of using the latter principle.
Wires and connectors have resistance. This simple, unavoidable truth dictates that a power source’s remote load voltage will be less than the source’s output voltage. In this application note from Linear Technology, figure one shows this and implies that intended load voltage can be maintained by raising regulator output. Unfortunately, line resistance and load variations introduce uncertainties, limiting achievable performance. Figure two illustrates one compensatory approach. Locally ...
Cultured dairy products, such as yoghurt, exhibit several physical properties that are important to consumers: firmness, creaminess, thickness or even heaviness or lightness. This article from Brookfield Engineering — whose products are distributed by Fullbrook Systems — compares two analytical test methods involving viscosity that effectively characterise these physical properties.
Drawing upon more than 40 years of experience, Trevor Foster — managing director of Titan Enterpises — offers sound, non-commercial advice on what to consider when selecting, implementing and maintaining a flowmeter system.
A capacitor is a device that stores electric charge. Capacitors vary in size and shape, but the basic configuration is two conductors separated by a dielectric. This article from Gill Research and Development provides more information on capacitive technology and its uses.
A general observation is that many powders, which exhibit only a small amount of compressibility (perhaps 10 per cent going from a loosely consolidated state to a consolidation pressure of 10kPa), will discharge from gravity feed hoppers with relative ease. A fair question to ask, according to Fullbrook Systems, is whether the density of a powder can be used to quantify or predict flowability.
