Technology package for acoustic upholstered furniture
Jerzy Smardzewski, Tadeusz Kamisiński, Artur Flach, Adam Pilch, Adam Majewski.

A technology package which constitutes know-how derived from research on acoustically passive materials for upholstered furniture production. The package includes the following technologies:

  1. Technology for layered components of upholstered furniture. The know-how relates to new models of upholstered furniture layouts and components with a high sound absorption coefficient and satisfactory ergonomic and technological properties. Different components (foam and fabric) were combined to create new composites of different thickness, density, cell wall structures and stiffness. As shown by research, the type and thickness of polyurethane foam is a decisive factor for the acoustic properties while the type of upholstery fabric does not significantly affect them. The know-how resulting from scientific research provides a basis for the construction of acoustic walls and partitions in office spaces.
  2. The technology related to the acoustic performance of noise walls for office desks and seats. The acoustic performance of selected office noise walls under model laboratory conditions was determined as per PN-ISO 10053: 2001: 2005. The results of research specify the structure and acoustic performance of noise walls for office spaces (especially for open-space offices).
  3. The technology related to the acoustic performance of armchairs with different geometries of back and side parts. The propagation of sound from a source located on, outside and away from the armchair to a receiver installed on the armchair was determined. The measurements were performed for several configurations with the sound source and the microphone being located at various heights. Three prototypes of upholstered furniture with various structures were selected for the test. The test confirmed the effectiveness of armchair noise walls. Depending on the configuration, the noise wall reduces the sound level by 6.7–12.2 dB, on average. The proposed solutions also confirm that the armchair designs reduce the sound level by no less than 2.7 dB.

The “Cellular board with a slatted core” technology consists of the right to obtain a patent for an invention (patent application No. P.410354 of December 3, 2014) and of unpatented non-public know-how.

The cellular board with a slatted core, made especially of fast-growing trees with low mechanical strength, is used as a component in furniture construction. The cellular board comprises cladding layers, conveniently made of three-ply poplar plywood. A core is positioned between the plies, preferably made of solid poplar wood slats. The core has the form of a lattice composed of three or more layers in which the construction element is made of wood slats with fibers arranged along their longitudinal axis. The fibers of adjacent slat layers are arranged perpendicularly to one another. The slats are arranged parallel to each other in each layer, maintaining a gap of 0.5 widths of the slat. The density of the slats is the same in each layer. The slats are connected with each other by means of a glue connection at the cross-points of the slats of adjacent layers. The slats of the outer layers of the core are connected to the cladding boards over the entire surface by means of an adhesive joint. According to the invention, the cellular board is characterized by high bending strength at low weight. The weight and bending strength can be adjusted with the spacing of the slatted core. As the solution relies on fast-growing tree species, it enables tapping into raw material resources which have not been used so far in the production of structural elements. According to the invention, the cellular board can be used as a load-bearing structural element of furniture installed horizontally.

Strain of Carnobacterium divergens S1 probiotic bacteria
professor Włodzimierz Grajek, Ph.D., Anna Sip, Ph.D., professor Antoni Przybył, Ph.D., professor Jan Mazurkiewicz, Ph.D.

Carnobacterium is closely related to Lactobacillus and, similarly, is able to produce lactic acid which reduces intestinal pH and consequently inhibits the growth of many microorganisms and microbes, including pathogens. An important role in this process is also played by bacteriocins synthesized by Carnobacterium. These compounds resemble antibiotics in many respects. However, in contrast, they are completely safe for humans and animals and do not initiate the formation of resistant microorganisms. The bacteriocins do not disturb the natural balance of the intestinal ecosystem due to the highly specific activity. This is because most bacteriocins have a narrow range of activity and affect only several groups of microorganisms.

The method and device for sticking narrow surfaces of panels, especially furniture boards
Bartosz Pałubicki, Ph.D. in engine

The “Method and device for sticking narrow surface of panels, especially furniture boards” technology consists of the right to obtain a patent for an invention (patent application No. P.418614 of September 8, 2016).

The developed solution consists in increasing the efficiency of the process of sticking narrow surfaces of panel elements by simultaneously covering two or more panel elements arranged so that their wide surfaces are parallel to each other. These elements are passed through the machine at the same time in such a way that all or some scheduled operations are carried out together, treating the parallel narrow surfaces as one. Instead of entering one form into the machine, a single set is introduced, consisting of at least two forms with the same shapes and dimensions, separated by a spacer element. The (intermediate) spacer element, which is a panel slightly smaller than the boarded elements, has a relatively high coefficient of friction on the panel, which reduces the risk of displacement of panels in the set during machining. Prior to (manual or automatic) feeding, the machine tool set is aligned so that the front narrow panel surfaces lie in one plane, for example by means of a pneumatic bumper. The feed system compresses and stabilizes the set during the passage through subsequent machine tool working units. The set is subjected to conventional, known and applied treatments in such a way as if it were a single panel element, and then additional operations are carried out on it to finish the rim in the center zone of the set (at the height of the spacer).

Membrane technology for treatment of water used for flexo plate preparation
Wojciech. Białas, Ph.D. in engineering

The purpose of this technology is to improve the quality of the preparation process of flexo plates made of photosensitive polymer for printing and to reduce rinsing water consumption. The technology consists in integrating the plate preparation device with the membrane separation system based on ultrafiltration. Also, the assumption is made that a method will be developed for the precipitation of polymer residues generated during the treatment of rinsing water. The existing technological solutions used to prepare flexo plates for printing consist in reusing rinsing water. Thus, the concentration of flushed polymer in water gradually increases. As a consequence, plate quality deteriorates considerably, and polymer residue progressively accumulates in operating components of the machinery. Shifting the technology towards ultrafiltration will enable a continuous separation of polymer residues, making it possible to reuse rinsing water over and over again. This will result in reducing the consumption of clean water and machinery maintenance chemicals. Another assumption is that the technology will use the flocculation process which will enable separating the concentrated polymer and reusing the water (which constitutes the retentate flow). This will allow to essentially minimize wastewater emissions (to ca. 10% of the level generated by existing technologies). Another important aspect is that the technology is not only innovative but also environmentally friendly.

Mobile compost sieve for small-scale installations
Robert Mazur, Ph.D., Krzysztof Górski, Ph.D. engineer, Jakub Mazurkiewicz M.Sc. in engineering

Small composting plants (up to 300 Mg per year) are often run by nurseries or operators such as botanical gardens or family allotment gardens. The operation of such installations is based on the use of mobile machinery primarily intended for gardening purposes: chippers, small tractors, garden loaders etc. The sufficient particle size of the final product is a major concern in the production of compost-based organic substrates. The product is made several times a year: a small batch, e.g. 100–150 m3, is ready every 3 to 4 months, and needs to be prepared (by sieving) in order to obtain the proper particle size and to separate non-decomposed particles and contamination, if any. The existing solutions are suitable for use on a much larger scale (in plants with a production potential of ca. Mg per year or more) because of high purchase costs, machinery footprint and transport issues (class C+E driver’s license is required). The existing sorters (e.g. for bark) are not set up to deal with the bulk density or specific nature of compost (much higher moisture content, different bulk density, different particle size, presence of larger objects). A large sieve may be rented for large product quantities which results in the need to store large quantities of nearly-finished materials, and afterwards to pass it through the sieve at once, and to start collecting large quantities of the product once again. In this context, note that the product is sold on an irregular basis over the year, and the ability to quickly prepare a batch of material on an ad-hoc basis plays a crucial role. The designed solution perfectly supplements the machinery of small composting plants and greenery managers which may extend their offering with services delivered at customer premises.
