Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
49 words
A method for the preparation of solid pharmaceuticals, which comprises dotting liquid, dissolved or suspended active substance in a specific quantity in the form of discrete droplets of specific volume onto a pharmaceutical carrier granulate in a mold before the pharmaceutical carrier granulate is pressed into tablets or cores.
Claim 2
Independent Claim
49 words
A method for the preparation of solid pharmaceuticals, which comprises dotting liquid, dissolved or suspended active substance in a specific quantity in the form of discrete droplets of specific volume onto a pharmaceutical carrier granulate in a mold before the pharmaceutical carrier granulate is pressed into tablets or cores.
Claim 3
Independent Claim
46 words
A method for the preparation of solid pharmaceuticals, which comprises dotting liquid, dissolved or suspended active substance in a specific quantity in the form of discrete droplets of specific volume onto pharmaceutical carrier in the powder bed of an unsealed capsule in a capsule filling machine.
Claim 4
Independent Claim
46 words
A method for the preparation of solid pharmaceuticals, which comprises dotting liquid, dissolved or suspended active substance in a specific quantity in the form of discrete droplets of specific volume onto pharmaceutical carrier in the powder bed of an unsealed capsule in a capsule filling machine.
Claim 5
Independent Claim
18 words
The method of claims 1, or 2, wherein the dotting is effected by means of piezoelectric dosing systems.
Claim 6
Dependent Claim
46 words
The method of claim 3, wherein a piezoelectric transducer wholly or partly encloses an outlet opening and the dotting is effected in such a way that the release of droplets from a liquid standing under pressure is achieved by the controlled opening of the outlet opening.
Claim 7
Independent Claim
52 words
The method of claims 1, or 2, wherein the liquid, dissolved or suspended active ingredient is broken up under high pressure during passage through a nozzle into discrete droplets of specific volume and the individual droplets are successively charged electrically and intermittently deflected electromagnetically to the desired points of the pharmaceutical carrier.
Claim 8
Independent Claim
118 words
The method of claims 1, or 2, wherein pharmaceutical carriers are dotted in series next to one another with the liquid, dissolved or suspended active substance. .[.7. The method of claims 1, or 2, wherein the liquid, dissolved or suspended active substance is dotted onto a flat pharmaceutical carrier in desired geometrical distributions..]. .[.8. The method of claims 1, or 2, wherein the liquid, dissolved or suspended active substance is dotted onto specific zones of a flat pharmaceutical carrier in doses different from one another..]. .[.9. The method of claims 1, wherein the liquid, dissolved or suspended active substance is mixed with a dyestuff and is dotted onto a pharmaceutical carrier to form a coding or letter characters..].
