CC-Link Partner Association (CLPA)Wed, 1 Oct 2014

Burgeoning industrial development throughout China will be one of the most influential driving forces that will determine global growth in the decades ahead. For ambitious companies in Europe, access to this vast marketplace is an essential step to enable them to capitalise on new opportunities for business growth. CLPA has a pivotal role both to create and to support greater European involvement in expanding Chinese market sectors through a groundbreaking initiative.

DV-II+ programmable viscometer measures at the lowest shear rates

Technical article: real-time monitoring of the rheological properties of fracturing fluids download

Fullbrook SystemsWed, 1 Oct 2014

Brookfield Engineering’s Charles Wesley recently presented ‘The Development and Real-Time Monitoring of the Rheological Properties of Frac Fluids Using Laboratory and In-Line Instruments’ at Oceantex. As part of the laboratory development of the fluid, its rheology must be measured, evaluated and understood over the majority of shear rates likely to be experienced at the well site so an understanding of the fluid’s behaviour is known before it is pumped through the system.

Audio precision 2722 analyser measures oscillator THD at –110dB, about 3ppm

Application note: fidelity testing for A→D converters download

Linear TechnologyMon, 29 Sep 2014

According to Linear Technology’s Jim Williams and Guy Hoover, the ability to faithfully digitise a sine wave is a sensitive test of high-resolution A?D converter fidelity. This test requires a sine-wave generator with residual distortion products approaching one part-per-million. Additionally, a computer-based A?D output monitor is necessary to read and display converter output spectral components.

Application note: application of fibre-optic photometry in continuous process control downloadweblink

Fullbrook SystemsThu, 25 Sep 2014

This article from Fullbrook Systems describes how photometry and the use of fibre-optic technology can be applied to the scale-up and continuous flow technology in the specialist fine chemicals industry. This discussion focuses on mature and commercially available technologies that can be applied across a broad spectrum of industries and applications.

Application note: TAOS colorimetry tutorial — the science of colour download

PacerThu, 25 Sep 2014

The purpose of this paper from Pacer is to give a brief overview of colorimetry. Colorimetry is the science of measuring colour and colour appearance. The main focus of colorimetry has been the development of methods for predicting perceptual matches on the basis of physical measurements. This topic is much too broad to be covered by one document, so a general coverage of the subject will be introduced.

Application note: closed-loop 100A active load brute force marries controlled speed download

Linear TechnologyWed, 24 Sep 2014

Digital systems, particularly microprocessors, furnish transient loads in the 100A range that a voltage regulator must service. Ideally, regulator output is invariant during a load transient. In practice, some variation is encountered and becomes problematic if allowable operating voltage tolerances are exceeded; 100A load steps exacerbate this issue. To meet this need, a closed-loop, 500kHz-bandwidth, linearly responding, 100A-capacity active load is used.

Long-term stability analysis

Technical article: Formulaction discusses development of pharmaceutical products download

Fullbrook SystemsTue, 23 Sep 2014

Ensuring the stability of pharmaceutical products is essential to make sure they are safe for patients. In addition, the range of product forms available and the various storage conditions make stability tests long and tedious. Finally, the number of components in these products leads to a complex interpretation of the data obtained via classical analytical techniques.


White paper: create class-A surfaces with Autodesk Alias Surface download

Man and Machine Mon, 22 Sep 2014

This white paper from Man and Machine discusses how Autodesk enables a more advanced workflow that helps automotive companies reduce rework and produce design iterations faster. Designers own their designs further into the development process, creating production-quality, reusable NURBS surfaces that can be used by the engineering team. The ability to create Bezier surfaces can help the engineering team improve surface quality up to class-A standards.

Technical article: improve your scavengers by ultrasonic mixing download

Hielscher USAFri, 19 Sep 2014

A scavenger is a chemical substance that is added to a mixture in order to remove or deactivate impurities and marring by-products. ln many reactions, an excess of starting materials is used to drive a solution phase reaction to completion. The final mixture is composed of the desired product and one or more unwanted side products. This article from Hielscher explains the uses of scavengers, the power of ultrasonic mixing and the benefits of ultrasonic scavenging and discusses batch ...

Brookfield DV-III Ultra Rheometer

Technical article: complying with 21CFR Part 11 in viscosity measurement download

Fullbrook SystemsFri, 19 Sep 2014

The pharmaceutical industry relies on viscosity measurement to qualify the flow behaviour of materials for a variety of applications. For example, the way in which a topical ointment squeezes out of the tube depends on the yield stress in the material. Too thin a formulation results in runny material flowing too easily from the orifice; too thick and the material is overly difficult to extract.

Application note: an introduction to acoustic thermometry — signal conditioning and jars download

Linear TechnologyFri, 19 Sep 2014

This application note from Linear Technology is based on a lecture by Jim Williams and Omar Sanchez-Felipe that investigates acoustic thermometry as an example of signal conditioning techniques. According to the lecturers, this subject has drawn enough interest that it is presented here for wider dissemination and as supplementary material for future acoustic thermometry lectures.

Technical article: it's all about bread — texture analysis of food products downloadweblink

Fullbrook SystemsThu, 18 Sep 2014

Over the years there have been many innovations in food ingredients and many new products have been introduced to take advantage of them. Many of them have one common theme: mouth feel is critical to consumer acceptance. In this article, Brookfield Engineering — whose products are distributed by Fullbrook Systems — takes a quick look at a gluten-free product and compares its properties with three other styles of bread.

Ultrasonic cavitation in liquid

Technical article: ultrasonically assisted catalytic extraction download

Hielscher USATue, 16 Sep 2014

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.

Technical article: what is induction technology and what are its uses? downloadweblink

Gill Research & DevelopmentMon, 15 Sep 2014

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.
