Pull-wire emergency stop switches are mounted on machines and sections of plants which cannot be protected by guards. In contrast to mushroom head Emergency Stop push buttons, on pull-wire switches the Emergency Stop command can be initiated from any point on the wire.
In combination with one of the AES and AZR range safety monitoring modules, see chapter 10.3, ZS range pull-wire emergency stop switches can be used for Control Category 3 or 4 to EN 954-1.
Design and mode of operation:
All of the pull-wire emergency stop switches conform to European Standard EN 418. They have a positive linkage between the NC contacts and the wire rope. The pull-wire emergency stop switches are brought into the operational condition by pre-tensioning the wire, i.e. the NC contacts are then closed and the NO contacts open.
Schmersal make both standard and AS-i Safety at Work pull-wire emergency stop switches.

Pizzato Elettrica has designed and patented new accessories to install the rope of safety switches faster and to obtain an aesthetically more pleasant system.
The new accessories, in comparison with the traditional fixing system through carpentry material, have the following advantages:
%u2022 The installation is faster because only one screw is used for the fastening of every rope extremity, and the parts are prepared to ease the installation. Some practical tests have pointed out that the installation time is halved, reason for which it is named FAST.
%u2022 The system is aesthetically pleasant, because thread parts (which sometimes tear operators%u2019 dresses) and the rope extremities, usually fixed by heat-shrinkable sheath or adhesive tape, have been hidden.
%u2022 The red plastic covers of the fixing parts have been developed also for the function of controlling the rope clamping. If the rope fastening screw is not fixed tightly enough, the cover cannot pass.
%u2022 The rope is fixed without folds, thus reducing the rope stabilisation time and the possible re-calibrations of the rope tightening.
Furthermore two sturdy pulleys has been introduced in applications where the rope is very long in order to support the rope length or to bend its route. They are designed to avoid any deformation and to allow the rope to remain in its seat also when it is energetically activated.

Loader seeds automatic rifle for sticks of paper for the line of feeding of a rotating one of press.
Semi-automatic loader for sticks of paper FOR the line of feeding of a rotating one of press.
It is equipped of a system of taken to pneumatic clamp opportunely sagomata and determine the proportions, joined to a balancing system automatic rifle of the cargo installed on an articulate arm or the flowing ways of race to carroponte.
It is used with nature acting on the commando console who is studied in order to guarantee ergonomics and operating rapidity; 4 sticks are loaded medium with paper to the minute.
The taken clamp of is constituted from two thin ganasce sagomate flowing ones for the taken one on the short side of the packages of paper; the wide faying surface of the ganasce avoids that the ream of paper is damaged on the flanks for effect of the serration force.
The commando console is Friendly, with prati push-buttons to us of dual-control for the drive of the clamp avoiding crushings or traumi to the limbs.
The balancing body of the machine works to compressed air 7 bars (0,7 mPa), is of highest reliability and duration in the time.
It can be installed in three various configurations:
on a double mounted articulate arm on a fixed column
on a double mounted articulate arm on a fixed column to a autostabile platform
on aerial flowing track on axis X or to carroponte on the aces X and Y.

With Stanley’s new iTrolley for enclosed and patented track rail systems, moving loads with large unwieldy bridge cranes is now possible with greater speed and precision than ever before. The system masks the momentum and inertia of the overhead crane, greatly reducing the starting-and-stopping strain that causes most operators to abandon the equipment and perform the task manually.

Constant Temperature Anemometry (CTA) - Hot-wire anemometry
Measurement of flows with very high turbulence and the study of flow micro structures
Hot-wire Anemometry or Constant Temperature Anemometry (CTA) is a point-measuring technique appropriate for the measurement of time series in 1, 2 or 3-dimensional gas and liquid flows.
CTA is particularly suitable for the measurement of flows with very fast fluctuations at a point (high turbulence) and the study of flow micro structures, where there is a need to resolve small flow eddies down to the order of tenths of a mm.

Zumbach WST TEMPMASTER Wire Preheaters
Excellence in Inductive Wire Preheating: Extrusion lines producing communication wire require optimum and repeatable conditions in order to produce valuable product at the highest speeds. Inductive preheating is clean and reliable. The adhesion is improved, humidity and other residues are removed from the conductor of data transmission cables. Many insulating materials can not be extruded successfully without preheating of the conductor. Cellular insulating materials require a uniform conductor temperature in order to produce a uniform cell structure and accurate electrical properties.
Main Benefits of Wire Preheating:
-Better product quality and improved consistency
-Dielectric properties of the insulation material are more uniform and the process conditions are reproducible
-Improved cell structure for foamed and foam skin insulating material
-Higher line speeds are possible thanks to lower stress within the insulation material
-Shorter start-up times
-Control of the bonding of the insulation material to the conductor
-Uniform conductor temperature maintained even during ramping phases
-The aging characteristics of the insulation are improved substantially through better uniformity
-Oil and water residues on the conductor surface are cleaned away by evaporation

Diversified industrial manufacturer Eaton Corporation announced today that at the end of June 2008, the hydraulic specialists from Eaton Aeroquip will extend their product portfolio with the addition of the GH 200 in sizes - 12 and - 16, a 4-spiral hose for standard applications in the high-pressure area. As a supplier of hydraulic components, Eaton is satisfying the particular requirements of its customers for high-performance yet low-cost DIN hoses for high-pressure applications. The new hose not only meets the requirements of DIN EN 856/4SH, it also significantly exceeds the 400,000 impulse cycles required in the norm at up to 420 bar work pressure.
Until now, the 4SH spiral hose GH506, which easily withstands 2 million flex-impulse cycles, accounted for most of production in the product portfolio of Eaton Aeroquip. It is used primarily in initial equipment. With the new GH200, for the first time customers can purchase a 4SH hose for standard applications with 500,000 impulse cycles. The new hose has been specifically developed for customers who require product that complies with the DIN standards. Product manager Kristin Fiolka explains: 'Compared to our competitors, the new hose programme is a very cost-effective solution for extreme-pressure applications based on standard conditions on the market. This price statement refers both to the hose as well as to the large number of fittings configurations of approx. 60 parts numbers.'
