Apparatus and a method for sea transport of liquids including a first enclosure, an at least partially flexible second enclosure disposed within the first enclosure and being adapted when filled, to generally fill the first enclosure, one of the first and second enclosures being a light liquid enclosure and the other of the first and second enclosures being a sea water enclosure, a light liquid port coupled to the light liquid enclosure for selectably filling it with a liquid lighter than sea water and a sea water port coupled to the sea water enclosure for selectably allowing sea water to fill it, thereby causing light liquid to be expelled against the force of gravity from the light liquid enclosure.

The apparatus of claim 9 wherein each of the bearing surfaces includes a rack, the pinion engaging both racks as the outer and inner column portions move relative to each other. 11. The apparatus of claim 10 wherein each of the bearing surfaces further includes a bearing race, the bearings captured between the races and within the cage. 12. An overbed table including a table portion and a telescoping support column including an outer column portion and an inner column portion, a table portion coupled to one of the outer and inner column portions, a base coupled to the other of the outer and inner column portions, the inner and outer column portions having surfaces adjacent each other, a bearing cage oriented between the adjacent surfaces of the inner and outer column portions, and bearings captured between the surfaces and the bearing cage, the bearings engaging the surfaces to promote projection of the inner column portion from, and retraction of the inner column portion into, the outer column portion, each of the surfaces including a rack, a pinion on the cage for engaging both racks as the outer and inner column portions move relative to each other, each of the surfaces further including a bearing race, the bearings captured between the races and within the cage, the bearings including roller bearings having axes of rotation, the axes of rotation of some of the bearings making non-zero angles with respect to the axes of rotation of others of the bearings. 13
