IPC: H01J37/20
Filed: 2011-11-18
Abstract: Protein layers 1 repeating regularly in two dimensions comprise protein protomers 2 which each comprise at least two monomers 5, 6 genetically fused together. The monomers 5, 6 are monomers of respective oligomer assemblies 3, 4 into which the monomers are assembled to assembly of the protein layer. The first oligomer assembly 3 belongs to a dihedral point group of order O, where O equals 3, 4 or 6 and has a set of O rotational symmetry axes of order 2. The second oligomer assembly 4 has a rotational symmetry axis of order 2. Due to the symmetry of the oligomer assemblies 3, 4, the rotational symmetry axes of each second oligomer assembly 4 is aligned with one of said set of O rotational symmetry axes of a first oligomer assembly 3 with 2 protomers being arranged symmetrically therearound. Thus, an 2-fold fusion between the oligomer assemblies 3, 4 is produced and the arrangements of the rotational symmetry axes of the oligomer assemblies 3, 4 cause the protein layer to repeat regularly. The protein layer has many uses, for example to support molecular entities for biosensing, x-ray crystallography or electron microscopy.

Abstract: Ο θαλάσσιος κυματισμός κινεί ένα πλωτήρα κατακόρυφα πάνω κάτω. Αυτές οι κινήσεις μεταφέρονται και μετατρέπονται σε περιστροφικές πάνω σε άξονα της ηλεκτρογεννήτριας. Ο πλωτήρας (1/1), σφαιρικού ή κυλινδρικού σχήματος κατασκευασμένος από πλαστικό ή μεταλλικό υλικό, γεμίζει με έρμα ώστε να επιπλέει βυθισμένος κατά το ήμισυ περίπου, καθώς κινείται απ' τις δυνάμεις των κυμάτων, μεταφέρει τις κατακόρυφες πάνω - κάτω κινήσεις του στην κατακόρυφη μεταλλική δοκό (1/2) η οποία μπορεί να αυξομειώνεται κατά το μήκος της ώστε να αντιμετωπίζονται παλιρροϊκές μεταβολές της επιφάνειας της θαλάσσης. Η κατακόρυφη αυτή δοκός συνδέεται με αρθρωτούς συνδέσμους, με το ένα άκρο της με τον πλωτήρα, και με το άλλο το άκρο με την οριζόντια δοκό του μεταλλικού ορθογώνιου τριγώνου το οποίο μεταφέρει τις κατακόρυφες κινήσεις, στο οριζοντίως κινούμενο μπρος πίσω πριόνι (1/5) με τις αλυσίδες (1/6) και (3/20) οι οποίες περιστρέφουν δυο ζεύγη οδοντωτών τροχών κάθε τροχό στην διαμετρικά αντίθετη πλευρά ώστε σε κάθε κίνηση, ο ένας τροχός να κινείται δυναμικά, ενώ ο άλλος τροχός του ζευγαριού κινείται ελεύθερα. Οι τροχοί περιστρέφουν τον οριζόντιο άξονα τον ενσωματωμένο σ αυτούς, (3/8) και ο άξονας δίνει κίνηση στην ηλεκτρογεννήτρια. Έτσι, κάθε κίνηση του πλωτήρα, είτε προς τα άνω είτε προς τα κάτω, μικρή ή μεγάλη, περιστρέφει τον άξονα και ενεργοποιεί την ηλεκτρογεννήτρια. Αυτός ο μηχανισμός, από τον πλωτήρα μέχρι την ηλεκτρογεννήτρια αποτελεί μια μονάδα. Πολλές μονάδες τοποθετημένες παράλληλα πλευρά με πλευρά η μια δίπλα στην άλλη, ενεργούν η κάθε μια με την δική της ηλεκτρογεννήτρια, ή δυο με τρείς μονάδες ενεργούν από κοινού σε κοινό στροφαλοφόρο άξονα, ο οποίο ενεργοποιεί ισχυρότερη

Abstract: The process consists in extracting, in a liquid-liquid extractor 1, the gallium present in a basic solution of sodium aluminate (Bayer liquor) by means of an extractant known under the tradename of Kelex, dissolved in an organic solvent. The organic phase containing the gallium is subjected to a first liquid-liquid extraction 2 by means of an acidic solution to remove, to at least a large extent, aluminium and sodium and then to a second liquid-liquid extraction 3 by means of another acidic solution to recover gallium. This acidic gallium solution is purified by extraction of gallium with an extractant at 4. After the extraction of gallium the acidic solution is recycled to the extractor 2 to reduce the usage of acid in the process. <IMAGE>
