Abstract: A vehicle electrical system includes dual alternator/battery sets separately connected to separate non-critical electrical loads, and both connected through a diode circuit to a critical electrical load. A starter switch connects both batteries to the engine starter motor.

Abstract: A snap-in LVDT force sensor includes a housing having separate chambers for enclosing an LVDT and an assembly of circuit components. One end of the housing is coupled for movement with one link of a two-link frame which is subject to the forces to be measured. A plunger is coupled for movement with the other link and includes a shaft which extends into one of the chambers to support an LVDT core for reciprocal movement within the LVDT coil assembly. A bellows is sealingly and flexibly coupled between the plunger and housing to provide protection from the environment. An optional spring may provide additional stiffness between the plunger and housing.

Abstract: A draft sensor includes a frame with an opening between a pair of spaced-apart portions which have a variable separation depending upon the force applied to the ends of the frame. Recesses or bores in the spaced-apart portions receive projections which project from the cap and base which form opposite ends of a transducer which contains a linear variable differential transformer. The transducer is spring-loaded to facilitate assembly or replacement of the transducer in the frame.

Abstract: A multiple mode control lever assembly includes a lever fixed for rotation with a disk rotatable on a central pivot in a housing. The disk includes detent recesses and carries a brake segment. A detent element is pivotal about a second pivot and carries a roller engageable with the detent recesses. A brake element is also pivotal about the second pivot and carries a brake shoe engageable with the brake segment. An index cam is rotatable on the central pivot to couple and uncouple the detent and friction elements from the disk. The index cam is rotated by a ratchet with a pawl reciprocated by a solenoid fixed in the housing. A centering spring continuously coupled between the housing and the disk urges the lever to a neutral position.
