Abstract: Amphibious landing stages or heavy loads are moved over the ground on systems of shoes. A landing stage comprises two port and starboard sets of legs fitted with shoes, which are themselves fitted with soles. Jacks are provided, to enable the sliding of a shoe on its sole, when the sole is applied to the ground, and to enable the reverse motion when the sole is raised. Other jacks either raise the legs or lower them. The legs are lodged inside lockers or wells by a simple locking device which also allows them to be removed. The stage is usable for temporary industrial installations, for wharves or jetties, serving for the displacement of very heavy loads.

Abstract: There is described a stump removing tool particularly designed for separating cauliflower flowerets from the stump thereof. It may also be useful for coring cabbages. The tool comprises a cylinder having an upper cutting edge and a nose piece, the apex of which includes meridian blades having cutting edges. When the nose piece is penetrating into the cauliflower head, the base of which is placed on the cylinder, the cauliflower flowerets are spread while the meridian blades first cut the cauliflower head center into tapers; then, the inside cylinder cut the stump into tapers which fall. A machine is also described which comprises a conveyor belt adapted to be advanced step by step, the belt carrying regularly spaced tool cylinders, and a vertical frame. A slide is in the frame and over the mounted tool nose pieces.
