Abstract
Abstract An apparatus for the continuous and direct measurement of the temperature of the upper superficial layer of the surface of the sea or other water surface, which apparatus comprises a central floating member and at least one arm connecting the central member to at least one peripheral floating element, the or each arm containing a thermal collector for transmitting heat to at least one temperature detector carried by the apparatus, wherein the central member and the peripheral floating element are adapted to maintain the apparatus on the water surface while at least a part of the or each arm is in contact with and senses the upper superficial layer of the water, and wherein electrical means are provided in the apparatus for the storage and/or transmission of temperature data from the or each temperature detector.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
143 words
An apparatus for continuous and direct temperature measurement of an upper superficial layer of a water surface, which apparatus comprises: a central floating member; at least one peripheral floating element; at least one arm transversely connecting the central member to the at least one peripheral floating element corresponding thereto; at least one temperature sensor detector carried by the apparatus; a thermal collector disposed in the at least one arm for transmitting heat to the at least one temperature detector; and electrical means in the apparatus for transmission of temperature data from the at least one temperature detector, wherein the central member and the at least one peripheral floating element are adapted to maintain the apparatus on the water surface while at least a part of the at least one arm is in contact with and senses the upper superficial layer of the water.
Claim 2
Independent Claim
143 words
An apparatus for continuous and direct temperature measurement of an upper superficial layer of a water surface, which apparatus comprises: a central floating member; at least one peripheral floating element; at least one arm transversely connecting the central member to the at least one peripheral floating element corresponding thereto; at least one temperature sensor detector carried by the apparatus; a thermal collector disposed in the at least one arm for transmitting heat to the at least one temperature detector; and electrical means in the apparatus for transmission of temperature data from the at least one temperature detector, wherein the central member and the at least one peripheral floating element are adapted to maintain the apparatus on the water surface while at least a part of the at least one arm is in contact with and senses the upper superficial layer of the water.
Claim 3
Dependent Claim
59 words
An apparatus as claimed in claim 1 wherein the central floating member is constituted by an external rigid resin surrounding an expanded insulating resin which encloses a thermoconducting resin, in whose middle is disposed a thermoresistance (thermistance), wherein each resin's density is less than water's density, and wherein the floating member's external surface is metallized and treated against biofouling.
Claim 4
Dependent Claim
49 words
An apparatus as claimed in claim 1 wherein the at least one arm is formed from a double layer of flexible plastics foils peripherally soldered together, in whose inside are superimposed said thermal collector in the form of a gold band, a coated paper band and an aluminum band.
Claim 5
Dependent Claim
33 words
An apparatus as claimed in claim 1 wherein the at least one peripheral floating element is constituted by a double layer of flexible plastics discs peripherally soldered together and containing a plastics washer.
Claim 6
Dependent Claim
34 words
An apparatus as claimed in claim 1 wherein the at least one peripheral floating element is constituted by a double layer of flexible plastics discs peripherally soldered together and containing a woven plastics disc.
Claim 7
Dependent Claim
50 words
An apparatus as claimed in claim 1 including a drifting buoy and electrical means comprising electrical and mechanical connections between the central floating member and said drifting buoy, which connections pass below the apparatus, through a cylindrical body centered on the central floating member's lower part and to the buoy.
Claim 8
Dependent Claim
35 words
An apparatus as claimed in claim 6 wherein the body centered on the central floating member's lower part and carrying the electrical and mechanical connections is in the form of and operates as a drift.
Claim 9
Dependent Claim
26 words
An apparatus as claimed in claim 6 wherein the said cylindrical body carries a further temperature detector for sensing water below the said upper superficial layer.
Claim 10
Dependent Claim
18 words
An apparatus as claimed in claim 1 wherein the electrical means comprise equipment for transmission of temperature data.
Claim 11
Dependent Claim
18 words
An apparatus as claimed in claim 1 including means for sensing air temperature immediately above the water surface.
Claim 12
Dependent Claim
24 words
An apparatus as claimed in claim 1 wherein the at least one temperature detector is disposed in the at least one peripheral floating element.
Claim 13
Dependent Claim
25 words
An apparatus as claimed in claim 1 wherein the central floating element and the at least one arm are adapted to reflect incident sun rays.
