Abstract
Abstract Apparatus is disclosed for treating dielectric material, which may be solid, liquid or gaseous, with microwaves. The apparatus comprises a cylindrical receptacle for the material and has one or more microwave antennae mounted within the receptacle for radiating microwave energy into the material to be treated. The form of the or each antennae is such that it defines a similar cylinder to the receptacle and is similarly oriented. For example, there may be a single antennae in the form of a rod or helix coaxial with the receptacle, or a plurality of rod-like antennae arranged to lie along respective generatrices of a cylinder surface coaxial with the receptacle. The or each antenna may be hollow and provided with longitudinal slots for radiating the energy. The apparatus provides uniform distribution of the energy along the length of the receptacle.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
102 words
Process for treating a confined material with microwaves consisting in entirely filling a receptacle with the material to be treated, the receptacle having a longitudinal axis and provided with an entirely internal, fixed antenna which is directly connected to a microwave generator and extends along a notional cylinder having the same axis as the receptacle, which is made with a plurality of elements able to radiate microwave energy, the antenna extending the full height of the material and is in direct contact with the material to be treated and radiating microwave energy from the antenna directly to the material to be treated.
Claim 2
Dependent Claim
102 words
Process for treating a confined material with microwaves consisting in entirely filling a receptacle with the material to be treated, the receptacle having a longitudinal axis and provided with an entirely internal, fixed antenna which is directly connected to a microwave generator and extends along a notional cylinder having the same axis as the receptacle, which is made with a plurality of elements able to radiate microwave energy, the antenna extending the full height of the material and is in direct contact with the material to be treated and radiating microwave energy from the antenna directly to the material to be treated.
Claim 3
Dependent Claim
24 words
The process of claim 1 which consists in radiating microwave energy from the antenna to the material to be treated perpendicularly to said axis.
Claim 4
Dependent Claim
13 words
The process of claim 1, wherein said confined material is a molecular sieve.
Claim 5
Dependent Claim
95 words
Apparatus for treating a confined material by microwaves comprising a microwave generator, a receptacle having a longitudinal axis for the material to be treated and entirely filled with the material to be treated and an entirely internal, fixed antenna which is directly connected to the generator, which extends along a notional cylinder having the same axis as the receptacle, which is made with a plurality of elements able to radiate microwave energy, the antenna extending the full height of the material and is in direct contact with the material to be treated in the receptacle.
Claim 6
Dependent Claim
95 words
Apparatus for treating a confined material by microwaves comprising a microwave generator, a receptacle having a longitudinal axis for the material to be treated and entirely filled with the material to be treated and an entirely internal, fixed antenna which is directly connected to the generator, which extends along a notional cylinder having the same axis as the receptacle, which is made with a plurality of elements able to radiate microwave energy, the antenna extending the full height of the material and is in direct contact with the material to be treated in the receptacle.
Claim 7
Dependent Claim
13 words
The apparatus of claim 4, wherein the antenna radiates perpendicularly to said axis.
Claim 8
Dependent Claim
17 words
The apparatus as claimed in claim 5, wherein said antenna extends along a generatrix of the receptacle.
Claim 9
Dependent Claim
17 words
The apparatus as claimed in claim 4, wherein said antenna extends along a generatrix of the receptacle.
Claim 10
Dependent Claim
15 words
The apparatus as claimed in claim 4, wherein said confined material is a molecular sieve.
