Patent ES-405031-A1 (ES)
Title: Heat transfer system for dynamoelectric machine
IPC: H02K9/06
Filed: 1972-07-21
Abstract: A dripproof dynamoelectric machine is described wherein air is admitted through the end shields directly into the end turn cavities at opposite ends of the machine to be circulated across the radially inner faces of the end turns before being expelled from the end of the machine whereat the air was admitted. The exhaust air then is directed across the motor frame by a shroud overlying the exhaust apertures to cool the stator by the transfer of heat from the stator laminations through the frame to the air circulating across the frame. Preferably the frame is finned to maximize the heat transfer surface in contact with the flowing air and the fans are secured to the rotor end rings. For increased volumetric flow of the air through the motor, the fans utilized to circulate the air through the end turn cavities underly the end turns adjacent the stator laminations and extend radially outward beyond the stator end turns to overlie the end turns.

Patent ES-481078-A1 (ES)
Title: I.C. Engines
IPC: F16M7/00
Filed: 1979-05-30
Abstract: A reciprocating-piston i.c. engine is supported on a supporting structure by means of mountings which are attached, not to the crankcase wall, but to the main bearing structure of the engine, by means of rigid support members which extend through flexibly-sealed apertures in the crankcase wall and are rigidly secured to the main bearing blocks. The crankcase wall is thus isolated from vibrations generated by internal moving parts of the engine, and the deformations of the crankcase by such vibrations, and hence the level of noise generated by the crankcase wall, are reduced. Where a longitudinal stiffening beam is secured to the bottom bearing blocks of the main bearing structure, some of the rigid supports of the mountings may be attached to the stiffening beam.
