Title: Hangar ribaltabile
Inventor: GHISI GUGLIELMO
Filed: 1994-05-15
Abstract: E' un ricovero per aerei, auto, bici o altro ancora. Comprende due tunnel a forma semicilindrica. La caratteristica principale sta nell'avere una luce per l'entrata ampia quanto la lunghezza del tunnel principale (1). Il tunnel principale (1) è intersecato ortogonalmente al centro del suo lato, che fa da perno (R) alla rotazione, da un secondo tunnel (2). Il tunnel principale (1) rotando sul suo asse longitudinale (R) sormonta il secondo (2) consentendo l'uscita dell'aereo o di quanto vi fosse ricoverato. Il tunnel principale (1) bilancia sull'asse di rotazione (R) per mezzo di contrappesi fissi (G) e variabili (F) che ne permettono il sollevamento anche manuale. L'angolo di rotazione non è fisso ma dipende dalle dimensioni del tunnel e dalle necessità di apertura. L"HANGAR RIBALTABILE" quando non vi sono particolari esigenze di profondità, può essere formato dalla sola parte principale (1).

Title: Reciprocal support of the linear motion of the action meeting the reaction.
Inventor: SERI RANIERO
Filed: 1995-12-07
Abstract: Unlimited energy for alternators, engines and pumps. (It seemed easier for me to develop the perpetual motion of the second wheel for a culture of PEACE, development, solidarity and sociality, friendship between individuals, families and peoples, or female culture, unlike the male culture of the first wheel. This wheel motion is not easy, but simple; inside it there is a motor system made of two plus two shafts fixed on two sides by two plus two wheels, with a tension bar to push the wheel and the active part of the stretched spring; also the reactive part on the central crown is held by a drive-belt which crosses over twice to engage it and also to contain the action force on the wheel. The inventor, Raniero SERI - Via Acquapagana 2 - CESI di Macerata -62038 - Italy, proposes the construction of silent electricity generators and CLAIMS: 1) each wheel propelled by a system with two tension bars (taut spring and/or jack and/or weight or other elastic device) on three wheels joined by a crossed drive-belt.
