CLASS 9 EUROINVENT 2010 CLASA 9 Descriere RO Inventia se refere la o instalatie de separare a unor compusi bioactivi, labili chimic si termic, prin extractie si transport prin membrane lichide (pertractie), in absenta (pertractie libera) sau in prezenta unor agenti purtatori (pertractie facilitata). Prin constructia sa, echipamentul nu necesita utilizarea unor agenti de stabilizare a membranei lichide, ceea ce sporeste puritatea compusilor separati. 9.3. Title EN New bent core liquid crystals with an asymmetric shape Titlu RO Noi cristale lichide de tip banană cu geometrie asimetrică Authors Elena-Raluca Cioancă, Irina Carlescu, Dan Scutaru Institution Gheorghe Asachi Technical University of <strong>Iasi</strong>, Faculty of Chemical Engineering and Environmental Protection Patent no. Pending Description EN Descriere RO [1,2,4]Oxadiazole derivatives are a new type of liquid crystalline (LC) compounds with symmetrical fivemembered heterocycle as a central unit. They have a bent shape and are very convenient model-compounds for studying the dependence of the LC properties on the molecular design. All the synthesized compounds presented enantiotropic liquid crystalline properties, evidenced by polarized optical microscopy and differential scanning calorimetry, mainly with nematic and smectic C type structures, with very large existence range of mesophases (more of 150 0 C, both on heating and cooling cycles). Derivaţii de [1,2,4]oxadiazol reprezintă o nouă clasă de compuşi lichid cristalini ce conţin un heterociclu simetric cu cinci atomi ca unitate centrală. Această clasă de compuşi are o formă de tip banană şi poate fi considerată drept model în studierea dependenţei proprietăţilor lichid cristaline de geometria moleculară. Toţi compuşii sintetizaţi au prezentat proprietăţi lichid cristaline enantiotrope, evidenţiate prin microscopie optică în lumină polarizată şi calorimetrie diferenţială, de tip nematic sau smectic C, cu domenii foarte largi de stabilitate a mezofazelor (mai mari de 150 0 C, atât pe ciclul de încălzire cât şi pe cel de răcire). 118
CLASS 9 EUROINVENT 2010 CLASA 9 9.4. Title EN A method for obtaining UV resistant cellulose textiles Titlu RO Procedeu de obţinere a unor ţesături celulozice rezistente la radiaţiile UV Authors Ana-Maria Grigoriu, Constantin Luca, Aurelia Grigoriu Institution „Gheorghe Asachi” Technical University of Iaşi Patent no. Hot. 4/226/30.10.2009 This invention deals with a method for obtaining UV resistant cellulose textiles by means of a nanometrical superficial finishing using the monochlorotriazinyl-β-cyclodextrin inclusion compounds with four UV absorbers: benzophenone, benzoin ethyl ether (2ethoxy-2-phenylacetophenone), Michler’s ketone (4,4’- Description EN bis(dimethylamino) benzophenone), ferulic acid (trans) (3-(4hydroxy-3-methoxyphenyl)-2-propenoic acid). The method implies two stages: the grafting of monochlorotriazinyl-β-cyclodextrin on the cellulose support – by means of a pad-dry-cure technique -, and the inclusion of the UV absorbers - by impregnation in solution. This finishing is effective and washproof. At industrial scale, it has as potential application the finishing of fabrics destined to summer clothes, clothes for sport and indoor activities, as well as to clothes used in special medical conditions (persons presenting Descriere RO photosensitivity and skin cancer). Invenţia se referă la un procedeu de obţinere a unor ţesături celulozice rezistente la radiaţiile UV, folosind un procedeu de finisare superficială nanometrică cu ajutorul compuşilor de incluziune ai monoclortriazinil-β-ciclodextrinei cu patru absorberi UV: benzofenona, benzoin-etil-eterul (2-etoxi-2-fenilacetofenonă), cetona Michler (4,4’-bis-dimetilamino- benzofenonă), acidul ferulic (trans) (acid 3-(4-hidroxi-3-metoxifenil)-2-propenoic). Procedeul presupune două etape: grefarea monoclortriazinil-β-ciclodextrinei pe suport celulozic - printr-o tehnică de tip fulardare-uscare-fixare termică-, şi includerea absorberilor UV - prin impregnare din soluţii. Această finisare prezintă eficienţă şi stabilitate la spălare. La scară industrială, invenţia are ca aplicaţie potenţială finisarea ţesăturilor destinate îmbrăcămintei de vară, a celei pentru activităţi sportive şi în aer liber sau pentru situaţii deosebite din punct de vedere medical (persoane fotosensibile sau cu un cancer al pielii). 9.5.
