Benefit to the User Computer Help Desk


A Help Desk helps corporate computer users by operating a simple single point of contact for all computer-related problems. Since the Help Desk is a single point of contact, users can submit all “service requests” to the Help Desk for repairs and assistance with their hardware, software, or networking issues. In some organizations, a Help Desk may be part of a larger Service Desk.

The Advantage of Having a Private Domain in the Online World


We live in a digital world. That’s a fact few will argue. The majority of us have, and use regularly, at least one account on a social networking site. We use these sites as a means to share our ideas, stay in touch with family and friends or to build our brand. Ultimately, however, if we don’t own a domain that’s personal to us, we don’t truly control our own message. Let’s look at what is meant by that, along with other ways that owning a personalized domain is advantageous in today’s online world.

Smartphone Apps that Can Improve Driving


As cars offer a heightened level of internet connectivity, there is an increased danger of potential driver distraction. Simply sending or receiving a text while driving can distract you from the road, increasing the chances of a collision. Although smartphones are part of this problem, there’s a wide range of apps on the market that can provide a potential solution. Mobile apps can not only prevent you from becoming distracted, but they can also monitor your speed and efficiency as a driver. The following are a few apps to explore if you’re looking for a way to sharpen your skills and focus behind the wheel.

Perfect contactor integration is the key to managed power distribution

As an electrical contractor or power distribution manager in a workplace environment, you’ll know the importance of safe, continuous, uninterrupted power distribution. You’ll know that the working principle of a contactor is similar to that of a relay but with a higher current rating. But where can you source contactor items and ancillary equipment which lives up to the demands of power distribution circuits in a modern workplace?


Arc danger

Wherever and whenever you need to get the best from the equipment which is in your charge, be they electric motors, thermal evaporators, lighting, capacitor banks or heating systems, rapid enhanced performance of the switch is crucial. There is a tendency for damage to occur as the contacts are opening and/or closing. As the contacts open and close the danger of arcing is ever present. The faster the contacts separate or connect, the less likelihood there is of arcing.

According to the RS components website from which much of this article research is drawn, contactors and the control systems in which they are designed to operate require perfect integration. For maximum efficiency and safety one such contactor which is designed for simple, rapid integration is the Schneider Electric TeSys D 3 pole design.

In modern contactors there is what is known as a tipping point mechanism which ensures a rapid opening/closing action every time. However, as with every upside there is a down side and that is no less true of electrical contactors. The downside of the processes of rapid opening and closing is, as you are probably well aware, a phenomenon known as ‘contact bounce’.

Unwanted open-close cycles

Contact bounce can cause additional and unwanted open-close cycles. If this happens the danger of arcing is exponentially increased. One solution to this issue is to have bifurcated contacts. This is a system where two contacts are designed to open and/or close simultaneously, but with an almost imperceptible time lag so the bounce is at slightly different times. This system ensures that the circuit disconnection is not an issue and arcing is avoided.

If arcing does occur in an electrical contactor this may have potentially explosive repercussions. Electrical circuits are designed to work in specific environments and are in the main sealed from the ambient environment. This is especially true where there is the potential for explosive or flammable gases or substances to compromise the interior of the system.

Although there is typically fail-safes built in to the design and operation of electrical systems, reduction of the potential risk is one benefit of bifurcated contacts. Another tried and trusted technique for improving the life (and overall safety function) of contactors is contact wipe. This involves a design where the contacts move past each other after initial contact, and in so doing will wipe off any contamination which would otherwise remain on the contacts points.

Electrical contractors and/or plant and power distribution managers requiring further information can check out the commercial contactors info available at RS for suitability and end application in relevant processes. Differing demands on equipment from industry to industry means a tailor made solution is the best way to fit the end process.

JUST EAT the online take away service are running such a fun and not to mention easy competition I thought I’d let everyone know about it on here. The competition is based around a game they have created where you have to find Mr Mozz’s pizza boxes in a large puzzle, sort of like a Where’s Wally thing. He’s left 8 boxes in there and if you find them all really quickly you win some nice prizes.
