Abstract: A self-leveling system for a multi-purpose vehicle used primarily for off the road operations such as roadside mowing. The vehicle frame and operator's station will automatically remain substantially level on sidehills, and if a slope greater than a predetermined amount is encountered, the operator will be given a warning signal which, if ignored, will result in the shut-down of the vehicle's operating system and the vehicle will stop. If the operator chooses, the vehicle can be operated from a remote location after the warning signal is received.

Abstract: A fluid pump for use in explosive bore holes comprising an elongated outer housing having upper and lower ends and adapted to permit water to enter the interior thereof. A hydraulic motor is secured to and is positioned in the lower end of the outer housing. A pump housing extends upwardly from the hydraulic motor within the outer housing. A drive shaft rotatably extends upwardly from the hydraulic motor within the pump housing and has a rotor means connected thereto for rotation therewith. The rotor rotatably extends through a pump stator means which is positioned in the pump housing. A pair of hydraulic hoses are in communication with a source of hydraulic fluid under pressure and extend downwardly into the outer housing between the outer housing and pump housing. The hoses are fluidly connected to the hydraulic motor.

Abstract: This application relates to a sleeving stand, a sleeving and a method of using a sleeving for loading blast holes with explosive, after those holes are lined with a blast hole liner in order to prevent water from interfering with the effective use of the explosive. The blast hole liner is of a convenient construction for easy use to line a blast hole and involves forward and rear panels and oppositely disposed gusset walls. The sleeving stand is a stand for use of the blast hole liner and for convenient dispensing of the blast hole liner in a blast hole.
