Abstract
Abstract A marine capsule for sea rescue and transportation having a generally spherical configuration and on its sides hermetically closed hatches of tempered glass and a sun-reflecting signal-sending film. At its top are four larger diameter hatches, two of which preferably permit access of persons or equipment into the capsule. Also there may be waterproof lateral access windows or openings for persons without seafaring experience. The other two overhead hatches have a ventilation system, which admits air but not water. A stowable stabilizing element has members which can be telescoped by a gear and crank system so as not to interfere with handling of the capsule when not in use, but to extend when it is afloat. Radial fins ending in a peripheral fin protrude from the lower outside of the capsule, and an air chamber is built into its body. Other interior equipment includes a seat extending all around, storage compartments, water and toilet.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
207 words
A marine lifesaving capsule of substantially spherical configuration carrying on the upper third of its body portholes which are watertight but allow the penetration of solar light; having doors or hatches for access disposed either on the top or the sides of its body; a series of radial fins on the bottom limited by a peripheral fin for stabilizing the capsule; an air chamber surrounding it the upper edge of which coincides substantially with the flotation line of the capsule; a telescoping stabilizing counterweight having its axis coinciding with the vertical axis of the capsule; a system of ventilation provided in at least two upper hatches of the capsule; and a ring-shaped seat under which several compartments are set off for storage of dehydrated provisions, including water, navigational equipment, toilet; said system of ventilation consisting of a hollow body provided with radial projections communicating with the interior of the body of the capsule by means of apertures, the said radial projections having cylindrical passages open to the atmosphere directed downward to each of the radial projections and partially obstructed by spherical boides which floatingly slide along the said cylindrical passages, permitting free passage of air into the said hollow body and obstructing the passage of water thereinto.
Claim 2
Dependent Claim
207 words
A marine lifesaving capsule of substantially spherical configuration carrying on the upper third of its body portholes which are watertight but allow the penetration of solar light; having doors or hatches for access disposed either on the top or the sides of its body; a series of radial fins on the bottom limited by a peripheral fin for stabilizing the capsule; an air chamber surrounding it the upper edge of which coincides substantially with the flotation line of the capsule; a telescoping stabilizing counterweight having its axis coinciding with the vertical axis of the capsule; a system of ventilation provided in at least two upper hatches of the capsule; and a ring-shaped seat under which several compartments are set off for storage of dehydrated provisions, including water, navigational equipment, toilet; said system of ventilation consisting of a hollow body provided with radial projections communicating with the interior of the body of the capsule by means of apertures, the said radial projections having cylindrical passages open to the atmosphere directed downward to each of the radial projections and partially obstructed by spherical boides which floatingly slide along the said cylindrical passages, permitting free passage of air into the said hollow body and obstructing the passage of water thereinto.
Claim 3
Dependent Claim
29 words
A marine lifesaving capsule as set forth in claim 1, in which the said system of ventilation is fixedly mounted on one of the upper hatches of the capsule.
Claim 4
Dependent Claim
39 words
A marine lifesaving capsule as set forth in claim 1, in which the access hatches are placed on the upper part of the capsule, permitting under conditions of a calm sea the ventilation of the inside of the capsule.
Claim 5
Dependent Claim
28 words
A marine lifesaving capsule us set forth in claims 1, in which the access doors are placed on the side of the capsule and their closure is watertight.
Claim 6
Dependent Claim
53 words
A marine lifesaving capsule as set forth in claim 1, in which the said air chamber is an integral part of the body of the capsule, the upper edge of which coinciding substantially with the flotation line, allowing the capsule to float even if it were entirely flooded through rupture of its walls.
Claim 7
Dependent Claim
65 words
A marine lifesaving capsule as set forth in claim 1, in which the telescoping stabilizing counterweight is composed of at least three hollow members of different cross-sectional area permitting the telescoping nesting of the same and an end component of heavy material in order to establish a point of gravity which can assure the suitable vertical position of the capsule under any condition of flotation.
Claim 8
Dependent Claim
78 words
A marine lifesaving capsule as set forth in claims 1 or 6 in which the said telescopic stabilizing counterweight is lowered or extended by means of a combination of gears and crank with the assistance of a cable secured to the bottommost piece of the said counterweight, guiding its extension by means of slots formed longitudinally in the component pieces thereof, in combination with pins which extend through the slots and constitute limiting stops for its maximum protraction.
Claim 9
Dependent Claim
38 words
A marine lifesaving capsule as set forth in claim 7, in which the said telescoping pieces of the stabilizing counterweight are accommodated in their retracted position within a housing which projects partially into the interior of the capsule.
Claim 10
Dependent Claim
110 words
A marine lifesaving capsule of substantially spherical configuration having at least two hatches disposed generally on the top of its body; and a system of ventilation provided in at least said two hatches, said system of ventilation consisting of a hollow body provided with radial projections communicating with the interior of the body of the capsule by means of apertures; the said radial projections having cylindrical passages open to the atmosphere directed downward to each of the radial projections and partially obstructed by spherical bodies which floatingly slide along the said cylindrical passages, permitting free passage of air into the said hollow body and obstructing the passage of water thereinto.
