Title: Removable neutron poisons for fission reactors
Inventor: IAN RICHARD SCOTT
IPC: G21C7/04
Filed: 2015-03-09
Abstract: Methods of controlling the reactivity of a molten salt reactor are disclosed, said reactor having a core, comprising a plurality of fuel tubes 103 containing a molten salt fissile fuel, immersed in a coolant tank 101 containing a molten salt coolant 102. The methods comprise dissolving at least one neutron absorbing compound in the molten salt coolant, said compound comprising a halogen and a neutron absorbing element. The compound may be chosen to act as a burnable poison such that a reduction in the neutron absorbing capacity thereof due to the absorption of neutrons compensates for a fall in reactivity of the core. Alternatively, the neutron absorbing compound may be chemically or electrochemically reduced to a salt of the halogen and an insoluble substance comprising the neutron absorbing element, the halogen being fluorine or chlorine, wherein the insoluble substance is not volatile at a temperature of the coolant during operation of the reactor.

Title: Bionic ray wing attachment, wing shape and actuation pattern for flapping propulsion
Inventor: JAY WILLIS
IPC: B63H1/32
Filed: 2021-09-09
Abstract: An underwater vehicle having a passive wing shape similar to a mobula ray wherein the vehicle has a bionic ray wing with two different axes of rotation on each wing consisting of front and rear axes D, E. The distance between the rear B axes E is less that that of the front A axes D with a ratio range between 4:2 and 4:3 for the axis span ration front:rear. For the wing to flap up and down in this configuration by means of rotational actuation on either or both axes the wing and armature must be flexible. When the wing and armature flex during the stroke they produce a tunnel-like feature on the wing which directs the thrust developed by the wing more toward the rear than it would otherwise be and thus is a more effective wing for propulsion.

Patent GR-920100294-A (GR)
Inventor: SHOFFNER JOHN
IPC: F16L11/12
Filed: 1992-07-06
Abstract: Η παρούσα εφεύρεση αφορά την κατασκευή σωληνώσεων από πολυαιθυλένιο, των οποίων η εσωτερική επιφάνεια αποτελείται από ειδικό στερεό υλικό που περιέχει πολυμερισμένη βάση καιλιπαντικά υλικά που το κάνουν να έχει πολύ χαμηλό συντελεστή τριβής. Η σωλήνωση αυτή χρησιμοποιείται για να εγκαθίστανται μέσα της και να προστατέυονται ευαίσθητα τηλεπικοινωνιακά καλώδια οπτικών ινών αλλά και οποιαδήποτε καλώδια ακόμα και ρεύματος.Η σωλήνωση κατ' αρχήν εγκαθίστανται μέσα στο έδαφος σε χαντάκια ή σε άλλες σωληνώσεις μεγάλης διατομής και μετά ακολουθεί η εγκατάσταση του καλωδίου που πρέπει να προστατευθεί. Ο πολύ μικρός συντελεστής τριβής κάνει πολύ εύκολη την εγκατάσταση του καλωδίου, όποια και να είναι η μέθοδος που χρησιμοποιείται. Ειδικά για τα 15 ευαίσθητα καλώδια οπτικών ινών με τον μικρό συντελεστή τριβής, επιτυγχάνεται πολύ μικρή φόρτιση του καλωδίου όταν "τραβιέται" ή "σπρώχνεται" κατά την εγκατάσταση, πράγμα που είναι πολύ σημαντικό για την διάρκεια ζωής και την απόδοση των οπτικών ινών.Το στερεό υλικό της εσωτερικής επιφάνειας έχει μεγάλη αντοχή στις αλλαγές θερμοκρασίας κια στην διάβρωση από υγρασία ή από συνηθισμένους ατμοσφαιρικούς ρύπους και διατηρεί το χαρακτηριστικό του πολύ μικρού συντελεστή τριβής για απροσδιόριστα μεγάλα χρονικά διαστήματα (πολύ περισσότερα από 50 χρόνια) έτσι ώστε αν χρειάζεται, η εγκατάσταση καλωδίων να μπορεί να γίνει πολλά χρόνια μετά την εγκατάσταση της σωλήνωσης. Η κατασκευή της σωλήνωσης γίνεται με ταυτόχρονη θερμή εξέλαση (coextrusion) του βασικού υλικού/τοιχώματος της σωλήνωσης από πολυαιθυλένιο και του ειδικού υλικού της εσωτερικής επιφάνειας (που περιέχει και τις μικροσφαίρες υάλου ή και νιφάδες γραφίτη), μέσα από ένα δακτυλοειδές καλούπι.Αυτά τα υλικά ενσωματώνονται με την κατά τα προηγούμενα δημιουργία ενός ομοιογενούς ξηρού μίγματος, που περιέχει και σφαιρίδια του λιπαντικού πολυμερούς υλικού. Το υλικό της εωστερικής επιφάνειας της γνωστής μέχρι τώρα τεχνολογίας έχει όλα τα προαναφερθέντα χαρακτηριστικά αλλά έχει περιορισμένη αντοχή σε υψηλή μηχανική και θερμική καταπόνηση/τρίψιμο. Αν δηλαδή κατά την εγκατάσταση κάποιου καλωδίου υπάρξει υψηλή φόρτιση στα σημεία επαφής του μανδύα του καλωδίου υπάρξει υψηλή φόρτιση στα σημεία επαφής του μανδύα του καλωδίου με την εσωτερική επιφάνεια της σωλήνωσης, είναι δυνατόν να τριφτεί και να αποξεστεί τελείως το ειδικό υλικό με αποτέλεσμα το σημείο εκείνο να παρουσιάσει δραματική αύξηση του συντελεστή τριβής. Αυτό συμβαίνει πολύ ευκολότερα, όταν το καλώδιο εγκαθίστανται με την βοήθεια κάποιου συρομένου μέσα στον σωλήνα σχοινιού, το οποίο συνήθως έχει πολύ τραχειά επιφάνεια και ξύνει εύκολα και καταστροφικά το ειδικό υλικό, δημιουργεί σημαντική αύξηση της θερμοκρασίας στα σημεία τριβής και προκαλεί την απόξεση του ειδικού υλικού με αποτέλεσμα την αναποτελεσματικότητα του εσωτερικού υλικού της επένδυσης. Με την προκείμενη σύνθεση του ειδικού υλικού και της μεθόδου παραγωγής της σωλήνωσης, επιτυγχάνεται όχι μόνο σημαντικά αυξημένη αλλά απόλυτη, μακροχρονιότατη αντοχή στο τρίψιμο
