Patent IT-MN950026-A1 (IT)
Title: Ammortizzatore idraulico per automodelli
IPC: B60G/
Filed: 1995-09-07
Abstract: Questo ammortizzatore idraulico per automodelli si basa sull'applicazione di tre principi basilari per il suo funzionamento mai utilizzati in alcuna applicazione del settore.1° Principio: volume costante dell'olio e pressione uniforme durante l'escursione del pistone: tanto asse inferiore entra nella canna tanto asse superiore esce.2° Principio: pistone guidato sopra e sotto in modo da mantenere inalterata la tolleranza stabilita con la canna: il passaggio dell'olio nell'intercapedine è costante.3° Principio: azione frenante costante degli anelli di tenuta degli steli che lubrificati dall'olio, eseguono una perfetta azione smorzante delle oscillazioni innescate, rugosità di canne e pistone, tipo di materiale usato e numero variabile di anelli di tenuta variano la capacità smorzante riducendo di gran lunga la sola funzione dell'olio a quasi solo lubrificante. Problemi precedenti: valvole di volume malfunzionanti, gas e aria-pistone che sfrega e varia la tolleranza con la parete.

Patent IT-TO941025-A1 (IT)
Title: W.c. attrezzato per bidet e lavapiedi.
Inventor: VALLINO PIER GIORGIO
Filed: 1994-12-16
Abstract: Il trovato è un sanitario simile al W.C. tradizionale, che, con opportune variazioni, viene trasformato in uno strumento più sofisticato, in grado di svolgere un numero maggiore di funzioni. In sostanza, sul corpo principale in ceramica, viene applicata una tavoletta in acrilico sagomata anatomicamente che, chiusa e riempita di acqua premiscelata può essere utilizzata come un normale bidet. L'acqua tiepida sarà miscelata alla fonte da un comune miscelatore monocomando e riempirà il bidet dopo la rotazione del rubinetto. Lo scarico dell'acqua di lavaggio avviene nel rimozione del tappo all'interno del vaso del W.C. Alla base di questo nuovo W.C. è posta una vaschetta lavapiedi in acrilico colato imperniata, su di una base fissa che ne permette la rotazione di 180°, permettendone l'uso come lavapiedi/pediluvio con l'utente seduto sul W.C. Il carico della acqua avviene a parete con miscelatore, lo scarico è a pavimento, attraverso una piatta fissata a pavimento; facendo coincidere - nella posizione aperta - lo scarico previsto nella vaschetta con quello fisso e di diametro superiore previsto nella piatta murata.
