Design and components for pneumatic control automation systems
The use of pneumatic process control systems has been adopted by a wide variety of industries and as the complexity of these control systems grows, so it becomes even more important to ensure high levels of reliability and integrity. However, not every system requires a huge valve island or bus communication to achieve the required level of automation. Neil Saunders, General Manager at Bürkert Fluid Control Systems looks at the common components and processes involved; from the most basic design to a complete production line.
Heat Pipes – Theory, Design and Applications, book review

Disc coupling range to suit all applications
Applications requiring disc couplings are found throughout industry, wherever the transfer of torque from driving to driven equipment is necessary. Typical applications include pumps, compressors, machine tools, engine driving equipment, food processing equipment, blowers and fans, covering a wide range of power requirements.
The barrier to tidal energy is not a mechanical one
The cost of energy generated by tidal power generation is, at this stage of device development, still more expensive than that offered by offshore and onshore wind, and solar arrays in sunnier climes; however, fossil fuels will not last forever and investment is still going into accessing tidal power, one of the most reliable and predictable of renewable energy sources. Anthony George, from the Heavy Duty Clutch and Brake (HDCB) Division of Altra Industrial Motion has been involved in engineering a number of offshore energy projects and offers some analysis on the real-world viability of these schemes.
Safe Systems of Work for confined spaces
Andy Richford, confined spaces and breathing apparatus specialist at PASS Training, contends that training for confined spaces needs to concentrate not only on Safe Systems of Work (SSoW) but also on self-rescue procedures and putting measures in place to avoid the need for having rescue teams placed on standby in the first place.
Understanding how fatigue contributes to rolling bearing failure
Fatigue is one of the primary causes of rolling bearing failure. In this article, Dr Steve Lacey, Engineering Manager at Schaeffler UK, describes the various types of fatigue and what measures can be taken to correct any problems that occur.
Alarm management systems: the benefits of third party software
When it comes to selecting an enterprise-wide alarm management system, businesses should consider the pros and cons of a third party specific alarm management tool over a DCS vendor’s offering, says Jason Cook, Product Manager at MAC Solutions.
New revisions to IEC 61496-1 (EN 61496-1) explained
The capabilities of light curtains and other optically-based ESPE (electro sensitive protective equipment or devices) have been something of a grey area in the past when assessing SIL levels to IEC 62061 or performance levels to ISO 13849. Now substantial revisions to IEC 61496 (EN 61496) at the start of 2014 are attempting to put that right. Dr Martin Kidman, a Safety Specialist at SICK (UK), explains how the changes affect the selection of appropriate protective devices in relation to the required performance level of the safety function.
