Abstract

'Ενα στοιχείο πυκνότητας (12) για χρήση σε συσκευές απελευθέρωσης στην προκοιλία μηρυκαστικών (10) που κατασκευάζεται κατόπιν μερικής περιτήξεως (συντήξεως) έτσι ώστε να θρυμματίζεται όταν έρχεται σε επαφή με πολλά τμήματα ενός μηχανήματος παραγωγής κρεάτων (σφακτών) χωρίς βλάβη στις λεπίδες. Το στοιχείο πυκνότητας 12 έχει πυκνότητα τουλάχιστον περίπου 1,5 gm/cm3 και εγκάρσια αντοχή θραύσεως μεγαλύτερη από περίπου 3000 psi (210 Kg/cm2), όχι δε μεγαλύτερη από περίπου 30.000 psi (2120 Kg/cm2). Το τμήμα περιτήκεται υπό τέτοιες συνθήκες ώστε να μην επιτρέπεται η απόκτηση πλήρους αντοχής δεσμού συγκολλήσεως και κατόπιν μπορεί να κατεργάζεται εν θερμώ ή να εμποτίζεται με ένα αδρανές υδρόφοβο υλικό για να αυξηθεί η αντίστασή του σε διάβρωση. ω
