Messe Wien Exhibition

Innovative printer solutions focus on the post-Expo 2013 citizen systems Europe is at the post Expo 2013 in Vienna launches the easy label printer CL-S321. At the fair, visitors can experience the compatibility and simplicity of the CL S321 immediately. Since the printer in daily operation is particularly reliable, it requires shorter maintenance times and less effort for training and support, leaving more time for its core business user. Design and development of the CL S321 are designed that customers can achieve reliable results at a competitive price even in hectic times. As a latest printer he joins specially in a long tradition of citizen label printers with proven performance features for the postal sector. The main strength of the CL S321 is that the printer EPL2 is compatible. Therefore, you can easily connect to existing systems and immediately start with the pressure.

In addition brings the printer both Ethernet, RS-232 and USB interfaces. With a print speed of up to 102 mm per second he contributes to productivity, where he offers both direct thermal and thermal transfer printing optional. The special citizen Hi-open to ensure high printing speed with minimal maintenance, allows easy change of media housing. Due to its compact and efficient design, the printer has small dimensions and thus saving space. His features are complemented by the operation via a single button so that the CL S321 emerges as a simple, durable and multi-compatible desktop solution. The post Expo 2013 takes 1 3 October 2013 held at the Messe Wien Exhibition & Congress Center in Vienna, Austria. Citizen issues 1134 at the booth.

The Time

Acoustics (Theatre). In a dwelling, it is desirable to a short but detectable reverberation time. We are now talking about noise. The noise can be transmitted through multiple pathways. Through the air or through a solid medium in which part of the sound it will reflect, some will be absorbed, and the remainder transmitted through the object.

The amount of sound reflected, absorbed or transmitted depends on the properties of the object, its shape, thickness and method of mounting, as well as the angle of incidence and the incident sound wave. The sound to move away from the source of noise intensity level decreases by 6 dB each time is twice the distance from the source in a free field. No less important are the materials: materials, in fact, in acoustics can be used to reduce the time of reverberation of a room or used as a barrier to reduce the intensity of the sound that travels from one point to another. Perhaps the most important of these materials are porous materials, which are constituted by a solid structure within which there is a series of cavities or pores interconected among themselves and with the outside world. Porous materials include rock wool, foam polystyrene, carpets, etc.

To modify the reverberations, the architect has two types of materials to cover surfaces in a room: that reflect sound and those who absorb it. The soft materials such as cork or felt absorb most of the sound that strikes them, although they may reflect some low frequency sounds. Hard materials such as stone or metals reflect almost all sound that reaches them. The acoustics of a large auditorium can be very different when it is full and when is empty: empty seats reflect the sound, while the audience absorbs it. In the majority of cases, the acoustics of a Hall is satisfactory if achieved an appropriate balance between sound-absorbent and reflective materials.
