Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
103 words
An underwater instrument for the combined reading of immersion time and depth, and decompression time, comprising, in combination, a depthometer (5), a clock device (8), a support (10) for decompression tables, and a casing (2) on which said depthometer (5), clock device (8) and support (10) are mounted in mutually side-by-side positions so as to be simultaneously consultable, said support for said decompression table being housed in said casing (2), and comprising a flexible band (10), and two drums (11,12) rotatably mounted in said casing (2), the opposing ends of said band (10) being wound in opposite directions about said two drums (11,12).
Claim 2
Dependent Claim
103 words
An underwater instrument for the combined reading of immersion time and depth, and decompression time, comprising, in combination, a depthometer (5), a clock device (8), a support (10) for decompression tables, and a casing (2) on which said depthometer (5), clock device (8) and support (10) are mounted in mutually side-by-side positions so as to be simultaneously consultable, said support for said decompression table being housed in said casing (2), and comprising a flexible band (10), and two drums (11,12) rotatably mounted in said casing (2), the opposing ends of said band (10) being wound in opposite directions about said two drums (11,12).
Claim 3
Dependent Claim
51 words
An instrument as claimed in claim 1, characterised in that said clock device (8) comprises first ring means (41) arranged to provide an indication of the total immersion time on a graduated dial (45), and second ring means (40) arranged to provide an indication of a plurality of partial immersion times.
Claim 4
Dependent Claim
36 words
An instrument as claimed in claim 1, characterised by further comprising correction tables (79) relative to decompression pauses for subsequent immersions; said correction tables (79) being reproduced on a side surface (3) of said casing (2).
Claim 5
Dependent Claim
107 words
An instrument as claimed in claim 1, characterised in that said casing (2) is substantially in the shape of an elongated parallelepiped bounded at its front by a surface (7) comprising a first and second transverse cup seat (6, 9) engaged respectively by said depthometer (5) and said clock device (8); said casing comprising a further longitudinal seat (13) extending between one of said two first seats (6, 9) and a rear surface (3) of said casing (2); said further seat (13) housing said support (10) for said decompression tables, and these latter being visible from the outside through a window (76) provided in said casing (2).
Claim 6
Dependent Claim
47 words
An instrument as claimed in claim 4, characterised in that said depthometer is a diaphragm depthometer comprising a flexible diaphragm (16) disposed facing a base wall (30) of said first seat (6); said base wall (30) comprising at least one through bore (35) communicating with the outside.
