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.


Technical article: what are the benefits of using ultrasonics for flow measurement? downloadweblink

Gill Research & DevelopmentWed, 10 Sep 2014

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.

Technical article: checking dairy products for consistency in viscosity downloadweblink

Fullbrook SystemsWed, 10 Sep 2014

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.

Brookfield powder flow tester

Technical article: can you predict powder flow behaviour by measuring density? download

Fullbrook SystemsMon, 8 Sep 2014

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.

Technical article: how sticky is your transdermal patch? downloadweblink

Fullbrook SystemsMon, 1 Sep 2014

The transdermal drug delivery system (TDDS) is the transport of therapeutic substances through the skin by means of diffusion in order to deliver the drug for its systemic effects at pre-determined and controlled rates. The TDDS consists of an outer impermeable membrane, a reservoir containing the drug (patch), a rate-limiting membrane and an adhesive frame. The adhesive frame helps maintain contact between the transdermal system and the skin surface when the patch is worn on the skin ...

White paper: coding and marking challenges — common industrial print techniques download

MicroscanThu, 28 Aug 2014

Codes and markings, from best-before and lot dates to EAN or data-matrix barcodes to serial batch numbers and various unique identifiers, are there to ensure traceability and product safety, to protect consumers and to avoid counterfeiting. There are many different print techniques that manufacturers can choose, such as continuous inkjet, thermal transfer or laser coding. All of these techniques have their advantages and challenges.

Tip-tilt mechanism

White paper: long-stroke/high-resolution tip-tilt mechanism downloadweblink

Cedrat Technologies S.AMon, 4 Aug 2014

Multi-degree-of-freedom (DoF) mechanisms are widely required in micro or macro manipulation fields as well as in optronics functions. Commonly available mechanisms may be divided into two main categories. The first is industrial robots (serial or parallel). These offer a large range of motion in rotation and translation. Their resolution is usually limited in the sub-millimetre range.
