TECHNOLOGY IN ACTION
Advertorial
or 150 years Fenner has been a leading name in power transmission, providing unparalleled reliability. History has shown that, whatever the challenge, Fenner belts and drives can meet the toughest demands. That point was proved beyond doubt in the 1960s when Fenner provided some extremely tough gear for Britain’s largest mobile crusher. Passing under the wheels of the millions of vehicles that travel the M2 motorway are hundreds of tons of stone, quarried and crushed by a colossally powerful piece of machinery called the Rock-Sledger. Designed by Parker’s of Leicester in the 1960s, the brilliant-yellow beast was created to accelerate the production of road base material, a feat that the 60-tonne 12-wheeler achieved at an astonishing rate of 300 tons per hour. Critical to its function were Fenner SpacesaVer belts and Torque-Arm drives, channelling power from the 170hp diesel engine that operated the crusher as well as secondary links between the crusher shaft and the apron feeder. It was these Fenner units that enabled the Rock-Sledger’s designers to generate phenomenal power from a very efficient design. The high rate of reduction achieved by SpacesaVer
Fenner then and now F
belts allowed Parker to use a high
speed diesel engine with a consequent reduction in the cost of the plant, while the narrower face width of the super-slim drive brought the overhung load well within the capacity of the standard engine bearings. The success of the operation prompted Parker, already a loyal customer, to fit Fenner wedge belts on all of its mobile crushers. Fenner continue to provide heavy duty equipment for harsh environments, and those wedge belts that Parker put so much trust in 50 years ago have continued to evolve and provide ever more reliable support. The Fenner Ultra PLUS 140 high strength wedge belt was launched in 2011, following some tough field testing within the Australian Mining industry that resulted in some special features being incorporated into the belts, such as the asymmetric double weave jacket and super-strength aramid cords. The Ultra PLUS 140 is of a construction that is in unique in the UK demonstrating the unbeatable strength of the Fenner Ultra PLUS 140 belts, maintaining the Fenner mark is still synonymous as a reliable and innovative provider of power transmissions solutions. Whatever the application, the Fenner name provides a complete drive solution from initial electrical input through to the final driven machine in one range with one result, driven performance - a fitting tribute to the designers and engineers who proudly continue to oversee these ever-improving fundamentals of power transmission.

Extended Travel Stands Improve Elasticity Testing
ecmesin, a British company specialising in force and torque measurement, has just launched new longer-length test stands for improved determination of break strength and elongation when testing rubber and film samples. The extended stands are constructed using a rigid aluminium base- casting and precision ballscrew, making them ideal for elongation testing up to 1200mm of highly elastic material such as rubber and film. To accommodate the
M
extra length and to comply with the EU Topple Test, these long stands are fitted with stability bases made of steel. The new 1kN and 0.5kN models are available with software and electronics from Mecmesin’s established range of MultiTest-d, MultiTest-xt and MultiTest-i tension and compression test frames. Thousands of companies worldwide use Mecmesin measurement systems to maintain consistency of manufacture to comply with relevant standards and to save money by minimising rejects in the production process.

produced. Still retaining practically the same original design, these connectors are used to provide power for electric awnings, blinds and shutters.
S have been selected for
use in NASA sounding rockets to control payload attitude. Alicat PC Series absolute pressure controllers provide the speed, accuracy and durability required for this mission-critical function. The Alicat PC Series absolute pressure controllers are used to directly feed the payload’s attitude control jets. The four pressure controllers are fed from a common gaseous argon manifold at approximately 160 psig, with a stock Alicat mulitdrop RS-232 sending set-point commands to the controllers. As soon as the rocket passes 100 km in altitude, all controllers are brought up to 5 PSIA with both pitch and yaw moments balanced. The spacecraft’s attitude is then modified by modulating the pressure commands sent to the Alicat controllers.

The ST-series of connectors celebrates its 40th birthday
ince 1971, well over a hundred million of Hirschmann™’s ST-series connectors have been
The
maximum rated voltage is 400 VAC/250 VDC, with a rated current of up to 16 VAC/10 VDC. Because the connectors are reliable, easy to install and have a long operational life they have become the standard for a wide range of applications including mechanical engineering, lighting technology and the medical sectors. This is why the ST-series remains an important part of the connector program and will continue to be further developed if necessary. The ST- series includes cable plugs and panel-mounted connectors together with their respective sockets. Four connector versions with different numbers of poles are available (2+PE, 3+PE, 4+PE, 5+PE). The outstanding quality of Hirschmann™ ST- connectors has assured them a place in history.
