Abstract
Abstract A moisture remover and a moisture removing apparatus which comprise a porous body and moisture-absorbing fillers basically. The porous body has continuous fine voids having a mean hole-diameter of 10 microns or less and a hollow portion therein to take out moisture and/or water. The moisture removing apparatus further comprises suction pump means for facilitating drawing of the moisture and/or the water.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
107 words
A moisture removal apparatus comprising: a porous body element, at least one internal hollow chamber within said porous body element adapted to collect moisture, said porous body element being formed with continuous fine pore voids having a mean pore-diameter of 10 microns or less, said fine pore voids being filled with moisture-absorbing sorbents, said at least one internal hollow chamber having an outlet for removal of moisture adapted to communicate with a suction pump means for decompressing said at least one internal hollow chamber whereby moisture absorbed by said moisture-absorbing sorbent can be communicated to said at least one internal hollow member for removal through said outlet.
Claim 2
Dependent Claim
107 words
A moisture removal apparatus comprising: a porous body element, at least one internal hollow chamber within said porous body element adapted to collect moisture, said porous body element being formed with continuous fine pore voids having a mean pore-diameter of 10 microns or less, said fine pore voids being filled with moisture-absorbing sorbents, said at least one internal hollow chamber having an outlet for removal of moisture adapted to communicate with a suction pump means for decompressing said at least one internal hollow chamber whereby moisture absorbed by said moisture-absorbing sorbent can be communicated to said at least one internal hollow member for removal through said outlet.
Claim 3
Dependent Claim
26 words
The moisture remover as defined in claim 1 wherein said at least one internal hollow chamber communicates with said suction pump means via a suction pipe.
Claim 4
Dependent Claim
81 words
A moisture remover comprising: a porous body element, at least one internal hollow chamber within said porous body element adapted to collect moisture, said porous body element being provided with continuous fine pore voids having a mean pore diameter of 10 microns or less, said fine pore voids being filled with moisture-absorbing sorbent, said hollow chamber having an outlet, whereby moisture absorbed by said moisture-absorbing sorbent is communicated to said at least one internal hollow chamber for removal through said outlet.
Claim 5
Dependent Claim
81 words
A moisture remover comprising: a porous body element, at least one internal hollow chamber within said porous body element adapted to collect moisture, said porous body element being provided with continuous fine pore voids having a mean pore diameter of 10 microns or less, said fine pore voids being filled with moisture-absorbing sorbent, said hollow chamber having an outlet, whereby moisture absorbed by said moisture-absorbing sorbent is communicated to said at least one internal hollow chamber for removal through said outlet.
