Correspondingly in the high driving range with a vehicle speed of lower the V.sub.2 the EGR ratio is made low, and in the high driving range with a vehicle speed of at least V.sub.2 the EGR ratio is made low and the air-fuel ratio is released from being set on the rich side.

Abstract: An electronic digital control system is disclosed for vehicle power transmissions, especially adapted for off-highway earth moving vehicles. Automatic forward speed range shifting is provided in response to the vehicle speed subject to certain overriding manual control. A transmission output speed signal is applied to a shift signal generating means which has a plurality of channels each corresponding to a different forward speed range. A level detecting means in each channel produces digital upshift and downshift signals and shift signal counting means, connected with all channels, produces a net count of upshift and downshift signal events and a command signal representing the speed range into which the transmission is to be shifted. A shift control circuit responds to the command signal to effect the required ratio change in the transmission.

Abstract: A projectile firing device utilizing a fluid propellant in which an electronic control responsive to a charging signal, cycling of the bolt in the breechblock to a fully closed position and pressure in the firing chamber below a preset value opens a valve to permit pressurized propellant to flow into the firing chamber and closes the valve and enables electronic triggering circuits when the pressure reaches the preset value. The muzzle velocity of the device may be varied by varying the pressure of the propellant in the firing chamber and the rate of fire in the automatic mode may be adjusted electronically. A spring biased injector finger carried by the bolt urges a projectile from a magazine into the bore of the barrel and retains it there to form a gas tight seal until the propellant is ignited. When no projectiles remain in the magazine, the injector finger prevents the bolt from closing completely and therefore inhibits the electronic control from recharging the firing chamber with propellant.

A spindle shaft holding or gripping means retains the hollow rotary spindle shaft in a stationary position when the draw bar actuator means moves the draw bar assembly between said operative and inoperative positions.

Abstract: A booster having a vacuum powered booster section and a hydraulic powered booster section which are normally actuated together to supply boosted force to a master cylinder. When the air valve of the vacuum booster section is operated to cause atmospheric air to enter the variable pressure chamber of the vacuum booster, it also engages and moves the hydraulic booster control valve to restrict hydraulic fluid flow therethrough, causing the hydraulic booster section control valve to be actuated to create a hydraulic pressure differential across the power wall of the hydraulic booster section. Both booster sections deliver boosted force through the output member of the hydraulic booster section to the master cylinder. Either booster section is operable when for any reason there is no power available for actuation of the other booster section.

Abstract: A hydraulic valve system particularly adapted for controlling a hydraulically powered elevator. The system involves essentially a bypass valve which selectively bypasses hydraulic fluid from the pump directly back to the tank during the up mode operation, thereby controlling the up speed of the elevator; and a down valve which selectively controls the escape of fluid from the elevator jack back to the tank, thereby controlling the down speed of the elevator. The down valve also serves as a check valve for retaining fluid pressure in the jack. Both the bypass valve and the down/check valve are each controlled by closely integrated cylinder-and-piston arrangement, with pressure to the cylinder being controlled by a control valve structurally interlinked to the respective piston. The bypass valve also serves as a check valve between the jack and the tank during the down mode of operation. The cylinder-and-piston control for the bypass valve makes possible an initial limit opening of the bypass valve, i.e.

Abstract: A high speed ground transportation system, is suspended in an underground vacuum tube by a frictionless magnetic suspension system and propelled by gravity. The tubes are suspended inside deep underground tunnels from anchor points near each adjacent station and follow smooth catenary curves similar to the main suspension cables of a suspension bridge. Gravity propulsion is accomplished by allowing the vehicle to coast down the descending arc of the tube, during which time it is accelerated by gravity, and decelerating by gravitational braking while coasting up the tube's ascending arc. Thus, the trip is accomplished by transforming the vehicle's gravitational potential energy at one station into kinetic energy and back into gravitational potential energy at the next station. Excess kinetic energy arising from coasting between stations having different elevations is supplied or absorbed by on-board linear motor/generators that provide supplementary propulsion or regenerative braking.
