Patent IT-226307-Z2 (IT)
Title: Caldaia-camino per riscaldamento dell'acqua alimentata da combustibilesolido con scambiatore di calore a quattro corpi ad alto rendimento termico dovuto al pieno sfruttamento del calore della combustione e di quello sensibile dei fumi
IPC: F24B/
Filed: 1993-03-03
Granted: 1997-06-03
Abstract: Il trovato si colloca nel settore della termotecnica. Esso si propone il pieno sfruttamento del calore sensibile trasportato dai fumi prodotti dalla combustione di combustibili solidi e nel contempo di evitare il deposito sui corpi dello scambiatore di calore dei loro distillati. Si è voluto ottenere il massimo rendimento ed una minima manutenzione dell'apparecchio. Superiormente alla camera di combustione è posto un particolare scambiatore di calore a quattro corpi. Questi sono disposti in modo da ottenere un percorso "tortuoso" per i fumi della combustione. Dopo una prima fase di accensione del camino, raggiunta la temperatura di regime, una valvola a farfalla posta allo ingresso della canna fumaria viene posizionata orizzontalmente e costringe i fumi al percorso precitato. Questi cedono così all'acqua contenuta nello scambiatore il loro calore sensibile. Alette a C, contenenti dei turbinatori ad elica, posti tra i corpi dello scambiatore, aumentano il rendimento e imprimono ai fumi un moto vorticoso che impedisce il deposito dei distillati. Le alette sono estraibili per la pulizia. Il trovato trova utilizzazione negli impianti di riscaldamento.

Patent GB-450091-A (GB)
Title: Automatic drifting device for locomotives
IPC: F01B25/00
Filed: 1935-01-04
Abstract: 450,091. Locomotives. TOMLINSON, J., 77, Gordon Road, Wanstead, London. Jan. 4, 1935, Nos. 302 and 303. [Class 79 (i)] Comprises apparatus for supplying drifting steam to the cylinders or steam pipes when a locomotive is running with the regulator closed, in combination with means controlled by the movement of the locomotive for automatically isolating or venting the supply of drifting steam and thus obviating the leakage of drifting steam to the cylinders &c. when the locomotive stops. In the construction shown, a casing 1 containing a drifting valve 2 is connected at 7 to the main steam supply and at 15 to the cylinders or the pipes leading to the steam chest. The space 10 above the valve 2 is thus always under steam-chest pressure. When the regulator is closed and the locomotive is running, a valve 6 is raised by a piston 17 dependent on the movement of the locomotive so that boiler steam is admitted from 7 through the valve to the underside 9 of the drifting valve. Since the steam chest pressure at 10 acting on valve 2 is negligible, the valve is raised and a small amount of steam is supplied to the steam-chest through ports 11, 12, the amount and pressure of the steam thus supplied being governed by the relative areas of the upper and lower pistons of the valve. When the locomotive stops the piston 17 falls, being no longer acted upon, the valve 6 closes and the steam in space 5 exhausts to the atmosphere at 21, so that valve 2 also falls and closes the ports 11, 12. When the locomotive is running with the regulator open the steam chest pressure at 10 keeps the drifting valve closed. The lower side of piston 17 is connected to the atmosphere and the upper side through a port 22, a to a vacuum pump (not shown), worked by a lever connected to a moving part of the locomotive, so that as long as the locomotive is running a vacuum is created above the piston 17 and tends to raise the latter to open the valve 6. The port 22 is connected to the atmosphere through a leak 23 and a filter 24 so that when the locomotive stops the remaining vacuum is destroyed and the piston 17 falls. When the piston 17 is raised it first closes the exhaust port 21 and then lifts a pilot valve 8 which balances the main valve 6 and allows the latter to be opened readily by the piston. A compressor may be used instead of a vacuum pump, the pressure produced being allowed to act on the underside of the piston 17 and being allowed to leak away when the locomotive stops. The piston 17 may be operated by the accumulated pressure of oil, water or steam, or may be raised and lowered by mechanical means such as a governor working in accordance with the movement of the locomotive.
