Abstract: An apparatus and method for effecting wheelbase adjustment for utility vehicles having one or more axles with wheels, includes one or more adjustment mechanisms to which compressed air can be applied. The adjustment mechanism(s) adjust at least one of the axles in relation to the body of the vehicle. A pressure sensor measures the pressure of the compressed air in the adjustment mechanism(s) and generates corresponding pressure signals. A pulse-controlled valve or, alternatively, a spring-return valve, is employed to optionally feed the compressed air into the adjustment mechanism(s) and discharge the compressed air from the adjustment mechanism(s).

Abstract: The carrier has beverage cup-holding receptacles on opposite sides of a vertical support panel, and a third much larger receptacle formed from the same blank. The carrier is stored flat and is unfolded for use at a usage location such as a motion picture theater concession stand, where it can be used to carry beverage cups in the smaller receptacles and a bucket of popcorn in the large receptacle. A tray can be mounted on an upright handle structure through a slot in the bottom, and can be used to carry other food item such as candy, hot dogs, etc. The carrier can be used to carry out fast foods such as fried chicken, french fries and beverages. Solid, bulky foods such as popcorn and fried chicken can be carried in the larger receptacle directly, without the use of a bucket or other separate container.
