Patent IT-1254604-B (IT)
Title: Converter of D.C. voltage modulated in phase with interrupters in line and cut-off resonant switching
IPC: H02M/
Filed: 1992-02-10
Granted: 1995-09-28
Abstract: The invention refers to a stabilised power supply and consists of a converter of D.C. voltage that is galvanically insulated. The circuit scheme of the switching unit of the converter, shown in the figure, is characterised topologically by the arrangement in line of the controlled interrupters. This has two half-bridges which are controlled by the phase mismatch of the commands to the interrupters; the phase mismatch leading the switching of the lower half-bridge relative to that of the upper half-bridge determines the output current and, consequently, controls the output voltage. The converter can operate at high efficiency, even at elevated switching frequency as well as constant frequency, since the switching transistors arrange to cancel out the voltage across each interrupter before it is switched on. <IMAGE>

Title: Procedure for moulding spectacle frames in plastic with the front and sidepieces in a single piece, injection mould for implementing the procedure and spectacle frames produced by means of it
IPC: B29D/
Filed: 1992-05-07
Granted: 1995-10-20
Abstract: The invention regards a procedure for moulding spectacle frames in plastic, the mould for implementing the procedure, and the frames so obtained. The latter has the front and sidepieces in a single piece with the hinge elements formed by slender foil staples. The main surface of the latter develops parallel to the hinging axis.

Title: Procedimento e apparecchiatura per tagliare a rotazione un tronco in un tornio per impiallacciatura
Inventor: NARITA MITSUMASA
IPC: B27B29/00
Filed: 1993-09-27
Granted: 1997-06-26
Abstract: Procedimento e apparecchiatura per tagliare a rotazione un tronco per sfogliare via una impiallacciatura mediante un coltello di taglio dalla periferia esterna di un tronco facendo al tempo stesso ruotare il tronco attorno al suo asse longitudinale. Il tronco o blocco di legname è afferrato in corrispondenza delle sue due facce di estremità mediante ganasce di mandrinatura che sono azionate girevolmente. Le ganasce di mandrinatura comprendono una pluralità di ganasce di mandrino che hanno posizione radiale diversa. Le ganasce afferrano il tronco in corrispondenza delle facce di estremità di esso adiacentemente alla superficie periferica esterna del tronco e quando il tronco viene tagliato dal coltello e ridotto di diametro in modo tale che il coltello si porta vicino ad una ganascia attualmente più esterna, la ganascia più esterna è retratta assialmente in allontanamento dalla faccia di estremità del tronco, e la ganascia più esterna successiva continua ad afferrare il tronco adiacentemente alla superficie periferica attualmente più esterna del tronco stesso. Per questa ragione, la forza di presa delle ganasce di mandrinatura, opponentesi al momento della forza di taglio, può essere resa piccola, e l'afferramento del tronco è reso affidabile.

Title: Element which makes it possible to prepare intradoses for doors of any width.
Inventor: PASQUINUCCI ROBERTO
IPC: E06B/
Filed: 1994-04-29
Granted: 1997-07-15
Abstract: This concerns a variable-length element which, when a board of a certain width is fitted to it, makes it possible to obtain a board of adjustable width on the basis of the user's construction needs. In this way, it is sufficient to store boards in two widths to be able to build frames and intradoses in a very great range of widths. Two advantages are contained in essence: lower storage space; greater constructive precision at millimetric level. The external effect is that of a common intrados, as if it were built from single-piece boards. <IMAGE>
