Abstract: A method for rapidly filling an aerosol spray dispenser containing a liquid with a soluble gas propellant including lifting the cap off the container and injecting the propellant into the container at a velocity sufficient to substantially saturate the liquid with the propellant.

Abstract: A bale positioning device is disclosed for positioning bales in a manner such that pickup by an agricultural loading machine is facilitated. The positioning device is mounted near the intake bale chute of a conventional bale loading machine and includes a spider wheel that is adjustably mounted for free rotation on one end of an arm that has the other end adjustably connected with a bell crank mechanism such that said spider wheel is both lifted and rotated upon actuation of the bell crank mechanism. When the spider wheel is brought into contact with a bale that is not properly positioned, the wheel will cause the bale to be shifted about a vertical axis and/or a horizontal axis as the machine proceeds forwardly to thereby properly position the bale for entry into the intake chute of the pickup machine.
