Abstract: A cargo ship construction comprises a ship which has a hull structure with at least one cargo storage space opening to at least one side both above and below the water line. A cargo storage container or warehouse of substantially the size of the cargo storage space of the vessel is insertable through the opening into the space. The container is associated with a flotation arrangement such as a separate propelled vehicle which may operate on either land or water and which is provided with a lifting section for lifting cargo storage container into the section. The device may travel on land and then float out to sea and load the cargo onto the vessel either by floating it in when the vessel is ballasted so that the opening is below the water line or the device may raise the cargo above the water level and permit it to slide into the receiving space of the vessel.

Abstract: A support structure for devices particularly life boats and similar apparatus which is weight operated comprises a plurality of support members, each or some of which may be telescopic which are pivotally interconnected adjacent their associated interconnected ends. Each successive upper one of a pair of such members is pivotal relative to the next adjacent lowermost one about a substantially horizontal axis. The pivoting is controlled by a control mechanism which is operated from a fluid pressure source produced by the weight of the elements upon each other. The control mechanism includes means for controlling the amount of tilt of each upper element relative to an adjacent lower element and for the control of the precise angularity of the two elements relative to each other during the pivotal movement.

Abstract: A paint roller construction comprises a roller which is supported on a support which has a handle. The support carries an electric drive motor for a pump which supplies a paint through a connecting conduit in the support directly into the roller. The interior of the roller is maintained at a predetermined pressure in order that the paint may be delivered outwardly through the pores of the roller applicator surface at a controlled rate for application on a surface. The device also advantageously includes a drive motor which may be operated at a selected speed in order to rotate the roller at an amount which is comparable to the pressure of the paint supply so as to apply the paint at a predetermined application rate and thickness.
