  • Patent number: 4135594
    Abstract: The invention concerns a device for recording and reading the itinerary travelled through by a vehicle and in particular an automobile vehicle such as an agricultural machine. The device is adapted to reproduce on an indicator band a trace of the path followed by the vehicle over a given surface so as to enable the operator to follow, with fidelity, in the course of a second passage of the vehicle, the trace of the preceding passage which permits, for example in the case of spraying, a rational treatment of the surface to be treated in strictly parallel strips with no omission or overlapping of zones. The device comprises a programmer constituted by the indicator band which travels at a speed which is proportional to the speed of the vehicle in front of a movable recording element which is controlled by the steering of the vehicle and reacts in accordance with the variations in the steering.

  • Patent number: 4135596
    Abstract: A hose tray for storing a fluid fill and drain hose for a liquid transport truck includes a cover having a closed position covering the tray to prevent access to, or accidental loss of, the hose and an open position permitting access to the hose. The tray is mounted on the vehicle adjacent, and extending longitudinally of, the liquid transport tank. The tray includes a safety interlock such that when the cover is in the open position, the truck brake system is actuated to prevent movement of the truck. This prevents movement of the truck such as would tear the hose from the truck drain fitting, causing spilling of the tank contents. This is extremely important, particularly in view of the flammable nature of many liquids transported in tank trucks, and further in view of the expense to repair torn and damaged drain hose and fittings for such trucks.

  • Patent number: 4134470
    Abstract: An aspirator using pressure from a suitable source boosts the vacuum available when intake vacuum drops. The pressure source may be the A.I.R. pump, for example. At low throttle settings engine vacuum is high and pump pressure is low. At 25% throttle engine vacuum is lower and the A.I.R. pump pressure is higher. With some flow the output vacuum from the aspirator is greater than the engine vacuum. This is also true at greater throttle openings. The device has a regulation effect causing output variation to be less than the variation in manifold vacuum. This makes the lock-up transient and lockup error less dependent on engine speed and makes cruise performance more uniform over the entire range of cruise speeds.

  • Patent number: 4133407
    Abstract: A manually controlled set-speed-selector on the speedometer of a vehicle causes a pair of normally open electrical contacts to close when the speedometer indicator needle reaches the set point. This actuates a solenoid valve which applies intake manifold vacuum to an accelerator actuator to pull on a chain connected to the accelerator, thereby decelerating the vehicle. A vacuum relief valve enables the driver to over-ride the decelerating action for passing or emergency purposes. The flexibility of the chain enables the driver to slow down at any time by simply releasing foot pressure on the accelerator. One electrical contact is connected to the speedometer indicator needle by a torsion spring, which allows the contacts to chatter as they close due to vehicle vibration. The on time of the chattering contacts increases as the set speed is exceeded and reaches 100% at a predetermined overspeed value.
