摘要:
A system for maximizing ground speed utilizing jet stream air currents and/or providing guidance along the path of least resistance by processing of dynamic pressure information signals derived at spaced apart points of different altitude levels. Dynamic pressures are continuously compared and aircraft altitude control or altitude direction indicator means responsive to the compared pressures are utilized to cause changes in aircraft altitude or indicate the changes to be made to achieve maximum ground speed through a path of less resistance, or achieve increased comfort by avoiding paths adjacent large pressure differentials.

A truck wheel dolly easily implaced and adjustable for use in lifting, transporting and remounting heavy truck wheels and tires, and this with a mimimum of effort or difficulty as such wheels are lifted, removed and replaced relative to the wheel axle. The dolly includes its own self-contained hydraulic jack with lever and like coupling means for lifting an elevatable frame supported by links to a base frame. The elevatable frame includes hinged support bars or means supplying versatility in use of the equipment. Wheel support bar means as well as auxiliary spacer bars are provided. Wheels and casters are supplied so as to provide fine adjustment in placement of the dolly preparatory to use. Support rail means is provided the lift frame so that a wheel may rest thereagainst and be supported thereby so that oil seals and the like at journaling areas will not be deleteriously disturbed.
摘要:
Systems for receiving the noise and/or exhaust emmisions transmitted from motor vehicle exhaust outlet arrangements. The motor vehicle transmitter of noise and/or exhaust emmissions have a modified tail pipe arrangement arranged for close coupling and transmission of the noise and/or exhaust emmissions to receiving means for collecting and processing the noise and/or exhaust emmissions. The receiving means extends along the length of the highway and attenuates the received noise and/or collecting and passing the received exhaust emmissions to processing means for recovering or purifying the exhaust emmissions. The duct portion of the receiving means instead or also utilized to provide transmission of electric power to specially designed types of electrically powered motor vehicles along the highway and also provide guidance where it is so desired to instrument the vehicle and duct.
摘要:
A system for modulation of the amplitude of engine exhaust feedback to the engine induction system during engine operation. The modulation system includes means for varying the amplitude of exhaust feedback in periodic manner at a frequency which is substantially constant or which may vary as a function of an engine operating parameter. The amplitude may vary as a step function between predetermined levels or continuously and may have a duty cycle (length of time at a predetermined level) which varies as a function of an engine operating parameter, e.g. exhaust manifold temperature. The modulation envelope is controlled by a modulator circuit controlling a valve position in the feedback path. The frequency of modulation is controlled by a divider or multiplier type circuit coupled between a pulse source e.g. the distributor and the modulator circuit.
