Solutions for Industrial Automation

November 2014

One of the many industrial automation applications served by NSF Controls is two piece can making machinery.

NSF Controls' stepping solenoids and low profile linear solenoids are used in some of the top performing systems on the market, with the need for highly productive and reliable processes being paramount.

The rotary compound end liners are used by the canning industry for applying lining compound to beverage can ends. The machines have 4, 6 or 8 cylinders each housing a gun which fires the compound into revolving can ends. A stepper solenoid incorporated in the gun determines the amount of compound to be dispensed, whilst a low profile linear solenoid dispenses the compound on to the revolving lid.

Aiding the Integration of Deaf Children in Education

January 2014

Connevans have been designing, manufacturing and supplying equipment for the deaf and hard of hearing in education or employment, at home or at leisure, for over 50 years. They have earned a reputation for their high standards in living aids, equipment and technology, which has resulted in a global customer base.

One of these is Russia, currently around a generation behind the UK in methods for educating deaf children. Up until fairly recently, deaf children were educated in schools for disabled children, much the same as was done in the UK until there was a major drive for integration into main stream environments. The Russian government are keen to educate disabled students in the same way as the rest of it's citizens and they are using some of Connevans' equipment to help achieve this.

An Auditory Trainer is a special audio amplifier, which feeds a high-powered headset. The system provides a depth and quality of sound that is widely considered beneficial for the auditory training of those with impaired hearing. It has been specifically designed to teach deaf children how to speak. The loud headphones enable them to hear their teacher's voice, then to hear their own, as they learn to copy the sounds.

The ATU30 units pictured can be used individually, linked as a pair, or in groups of up to 10 for class work. We are proud to have assisted, albeit in a small way, by manufacturing and supplying specialist rotary wafer switches for use in this life enhancing equipment.

At a school in Tambov, a city about 480 kilometers south-southeast of Moscow, Maria heard her own voice for the first time in her life recently. At the age of 16, on hearing herself, she was amazed and excited. With the continued aid of the amplifier, she is now able to learn to speak in the same way as her family and friends.

As well as exports to Russia, the unit has succeeded in several other countries such as Lithuania, Nigeria, Taiwan and China. It is hoped that production from the Surrey based factory will continue to contribute to the positive inroads made by educational establishments around the world.

Rotary Solenoid by NSF Improves Existing Product

March 2013

Solenoids are being used in ever more innovative ways. We are often approached to collaborate with manufacturers or design houses to provide customised actuation solutions for new projects. However, more often than not it is existing applications that are brought to us with the potential for improvement.

NSF were recently approached for development input on a product already on the market.

The gun dog training aid had already made headway in it's field, however, scope had been identified for substantial distribution increases subject to solving a particular issue.

The gun which fires dummy objects had limited power capabilities, resulting in training session lengths being compromised and market growth being hindered.

Using a solenoid as alternative means of drive meant several application specific issues needed to be satisfactorily addressed. We worked with the company to find suitable solutions and meet the challenge of improving performance whilst keeping the finished product within budgetary requirements.

Being particularly proud of their Made in UK status, the UK manufactured NSF rotary solenoid completes the package and following positive test results, the outcome is a gun dog training aid product with greater reliability and increased operational lifespan.
