Abstract: An air resistance reducing assembly for use in tandemly coupled vehicles, one of the vehicles being a hauling, another of the vehicles being a trailing vehicle, the trailing vehicle including a front wall and a top panel, an the air deflector having leading and trailing edges disposed transversely of the direction of forward movement of the vehicles and carried at an upper leading end portion of the trailing vehicle, the deflector overlying the surface of upper leading end portion while remaining disposed respectively behind and below the plane of the front wall and the top panel, the air deflector being formed and disposed to deflect air to pass therebeneath adjacent the surface of the upper leading end portion and along the top of the trailing vehicle.

Abstract: System for remotely measuring the air pressure in pneumatic tires. The system includes a stationary power transmitter that generates an electromagnetic field in the roadway with a flat coil antenna. Located in the pneumatic tire is a pressure sensor comprising a pressure transducer and a signal transmitter both powered by the energy obtained from the electromagnetic field in the roadway. The pressure sensor does not use a battery and has no external physical connections outside of the tire. The pressure sensor transmits a low frequency FM signal to a stationary tire pressure signal processor. The signal processor generates quantitative signals representing the pressure in the tire, visually displays these signals, and passes the signals to a computer. By means of various antenna configurations the system can distinguish between tires mounted both in side by side and in tandem relationship. Moreover, by coding the FM signal the system can uniquely identify the vehicle as well as every tire thereon.

Abstract: A turbocharger and intake air cleaning device for use with internal combustion engines. A collection spout is mounted tangent to the volute of the diffuser housing at a position from the turbocharger's discharge port which is upstream relative to the direction of rotation of air within the housing. A nozzle is mounted in the distal end of the collection spout. Dirt and other foreign matter carried in the rotating air stream migrates by centrifugal action into the collection spout where it is separated from compressed air flowing through the discharge port. An opening in the nozzle expels the foreign matter while at the same time limiting air leakage so as to maintain boost pressure within the diffuser.
