Abstract: A spraying apparatus that is particularly suited to spraying of suspensions, for example liquid suspended fertilizers. The apparatus includes a tank with an arrangement configured to create fluid circulation within the tank, thereby reducing settling of solids out of suspension. The apparatus also creates a mixing flow in a region below an opening, such that particulates can be introduced through the opening into the mixing flow.

Abstract: A spraying apparatus that is particularly suited to spraying of suspensions, for example liquid suspended fertilizers. The apparatus includes a tank with an inlet configured to create fluid circulation within the tank, thereby reducing settling of solids out of suspension. A mixing unit improves the mixing of particulates with fluids as they are added to the tank. Spray outlets are arranged in a flow loop and only a proportion of fluid passing through the flow loop is sprayed with the remaining fluid returning to the tank for recirculation. Pressure-actuated closures may be used to prevent spraying until pressure has built up sufficiently.

Abstract: A wheelchair includes a chassis with rear wheels and front wheels mounted thereto. A support is pivotally coupled by a pivot axis to the chassis. A seat mount is pivotally coupled to the support. An electric actuator can move the support to cause the seat mount to be moved between raised and lowered positions. A clearance is provided between one or more power supply units and suspension mounts to enable the support to move therein during movement of the seat mount to and from the lowered position. The support and actuator are mounted by a mounting assembly that is mounted by guides so that the mounting assembly can be raised by the actuator to further elevate the seat mount.
