Abstract: A steerable axle includes a housing defining a ball seat therein, a ball member received within the ball seat and defining a cutout portion to receive a portion of a ball bearing therein, an interstitial space defined by a surface of the ball seat and a surface of the ball member, and a ball bearing disposed within the interstitial space and received into the cutout portion of the ball member. The ball bearing moves within the interstitial space when the ball member rotates along the x or y axis, but is restricted from movement along the z axis. Restriction of movement of the ball bearing along the z axis results in a corresponding restriction of movement of the ball member along the z axis.

Abstract: A training device provides a simulator for gaining emergency access through a locked or barricaded door in emergency situations. The apparatus comprises a door support structure, which may be free-standing. The door support structure comprises a vertical rectangular support structure comprising a threshold member at the bottom, a head member at the top, a hinge side jamb member and a latch side jamb member. A vertical hinge attachment member is pivotally mounted to the hinge side jamb member. A door member translates with respect to the position of the vertical hinge attachment member along a plurality of pins extending between the vertical attachment member and the door member. The door member is normally biased towards the latch side jamb member.

Abstract: A mobile harvesting unit which utilizes a high volume fan to separate crops from foreign matter, has a dust suppression system which substantially reduces particulates which are discharged with the fan exhaust. The dust suppression system has two stages. The first stage separates larger particles of foreign matter by deploying an air stream cleaning chain upstream of the fan. The second stage is contained within a air stream discharge duct. Within the air stream discharge duct, a liquid, such as water, is sprayed into the dust entrained air stream. The moistened air stream flows through a plurality of collection members which extend radially from a brush drum, where the moistened dust particles are accumulated on the collection members, such that the volume of dust particles contained within the air discharged from the harvesting unit is substantially reduced.

Abstract: A low-profile sweeper that employs rotary brushes. The low-profile sweeper is especially suited for low overhead clearance applications, as typically found in nut harvesting. The low-profile sweeper has an armature for locating one or more brushes in an array, or attached to a conventional agricultural sweeper. The armature attaches to a chassis or frame of a steerable drive. When used in a parallel oriented array, the brushes rotate in the same, common direction and in substantially the same, common plane of rotation, slightly skewed to avoid contact between the brushes. The bristles of the radial brushes are emanate fro a central hub and are approximately parallel to the plane of rotation. A fan can be utilized to aid the pick-up action of the brushes. The fan is preferably mounted to direct an airstream to the area to be swept. Also, a spray-bar can be attached to the armature or alternatively to the chassis, to aid in dust abatement.
