In a unilateral NMR probe for the analysis of a material comprising at least one magnet for generating a constant time-invariant polarization field Bin the material to be analyzed and current conductors forming a radio frequency oscillation circuit for generating a pulsed radio frequency magnetic excitation field Bwhich is superimposed on the polarization field Nin the material, the circuit conductors are so designed as to provide several adjacent excitation fields Bwith alternatingly oppositely oriented magnetic fields, whereby the current conductors generating each one of the excitation fields have a distance from each other which causes a certain penetration depth in the material to be analyzed and echoes received therefrom provide measurement values which are characteristic for the material being analyzed.

NMR probe for material analysis

The invention relates to a plaster containing an active agent, comprising at least one cover membrane and an active membrane which is based on a skin-compatible matrix containing a molecular sieve which is loaded with at least one active agent. The molecular sieve/active agent adduct releases the active agent when the active membrane comes into contact with the skin, in conjunction with the transpired water of the skin. The inventive plaster is characterised in that the molecular sieve/active agent adduct also contains water of crystallisation, to the extent that the molecular sieve is partially hydrated compared to a sufficient basic molar quantity (m) of water of crystallisation, the molecular sieve with the reduced molar quantity (m') of water of crystallisation being loaded with the active agent (Z, Z, Z) so that when the active membrane comes into contact with the skin, water is absorbed and the active agent is desorbed, whereupon the water of crystallisation content of the molecular sieve increases. The invention also relates to various suitable embodiments of the plaster containing an active agent and to an advantageous method for producing the inventive plaster containing an active agent.

A medical cushion (), in particular an anti-decubitus cushion, is in particular multicellular and is distinguished in that the cushion is equipped, at least in the area where skin contact () occurs, with an active membrane () based on a skin-compatible matrix () into which a molecular sieve is mixed. This molecular sieve is charged with at least one active substance (Z, Z, Z), and the molecular sieve/active substance adduct () releases the active substance when the active membrane comes into skin contact () in conjunction with the transpiration of the skin.

The invention relates to a rail arrangement for a rail superstucture such as a fixed railroad, comprising an elastic intermediate plate ( ) which is located between the rail foot and a hard support (6) in the form of a concrete tie and has two through holes for the screws ( ) to fasten the rails. For series mounting, which is the solution of choice, the elastic intermediate plate ( ) is combined with an elastic intermediate layer ( ) in such a way that the additional intermediate layer rests above the intermediate plate directly below the rail foot, whereby the intermediate layer ( ) is separated from the intermediate plate ( ) by a metal base plate ( ) which serves to fasten the rail. According to the invention, the intermediate plate ( ) consists of a single-piece vulcanisate made of a rubber mixture and has three structural zones related to a novel arrangement of protrusions (active surfaces) and recesses (inactive surfaces), whereby the inactive surfaces in the central zone are deeper than those in the two side zones. The invention also relates to other constructional features of the elastic intermediate plate ( ).
