Abstract: An improved tamper resistant combination lock with large planar easy to shift blocking slides with spring fingers that fool the lock picker into believing all three positions of the slides are blocking positions, rather than passing positions. The slides block or pass spaced spheroidal obstructions on a plunger. A small bifurcated clip prevents the complete removal of the plunger when all blocking slides are in the pass position. In one embodiment the lock is a padlock-type with a "U" shaped shackle that lies in a common plane with the slides to reduce lock size.

Abstract: The system comprises a zirconium sensor interposed in the exhaust conduit of a gas-fueled engine for sensing both oxygen content and temperature of the exhaust gases, and for emitting electrical analog signals thereof to a comparator/controller. In turn, the latter transmits a complementary, derivative electrical signal to a current-to-pressure transducer. The transducer is supplied with gas under pressure, from the engine fuel (gas) supply line, and the pressure of this transducer-supplied gas is modulated by the aforesaid derivative signal. The modulated gas pressure is communicated with a gas cylinder, having a translating piston rod, which is operatively engaged with an otherwise standard gas engine regulator for trimming control of the flow of fuel (gas) through the regulator.
