Patent DE-4223004-A1 (DE)
Inventor: LIEDTKE RAINER K DR
IPC: A61M35/00
Filed: 1992-07-13
Abstract: To improve the efficacy and tolerability of conventional topical applications for medicinal substances which have a transdermal systemic action, single-dose topical dosage forms which are ready for accurate therapeutic use are produced from suitable semisolid dosage forms. The topical single doses are pharmaceutically specified in terms of their dose, their topical spreading behaviour and their permeation properties. A plurality of the single doses which are ready for topical use is moreover accommodated in a common technical carrier container. Differentiated therapies can be designed by means of different single dosages or else combinations of active ingredients. The pharmacological active ingredients which are particularly employed are steroids, peptides, various analgesics, local anaesthetics and non-steroidal antirheumatic agents. The single-dose topical dosage form is a safe, user-friendly and slow-cost application form which makes it possible for topical therapy for systemic uses to be more accurate than hitherto achievable with conventional topical use forms.

Patent DE-4304499-A1 (DE)
Inventor: KRAMER CHARLES J
IPC: G02B27/00
Filed: 1993-02-15
Abstract: Dual reflection unpolarizing monofacet (DRUM) scanner or beam deflector has a hypotenuse face 32 and forms a body which may be rectangular or cylindrical and may be contained in a housing which provides for aerodynamic stability when the scanner rotates at high speed. The hypotenuse face has a partially reflective surface on which an incident beam, collinear with the rotational axis, is incident. This beam is transmitted and reflected to provide dual beams, one of which is absorbed by light absorbing material 46, preferably a coating, on a surface of the body and the transmitted beam is retroreflected by a mirror 34 on another surface of the body, back to the partially reflective surface. An output beam is provided by the retroreflected beam. The DRUM deflector may be part of a system which provides a tracking beam of a wavelength different from the scanning beam which is reflected from the partially reflecting surface, then acting as a dichroic beam splitter (Fig 22). Also laser beam scanners having a polarization sensitive beam deflecting surface (specifically a monofacet nondisc plane diffraction grating (NPDG) monofacet deflector and a dual reflection monofacet polarization sensitive deflector that incorporates a polarizing beam splitter cube) achieve essentially 100% radiometric throughput efficiency while also achieving a scan beam intensity that stays constant over the total range of scan angles by using a circularly polarized incident beam and a quarter-wave retardation plate at the entrance aperture of the scanner assembly so that the quarter-wave plate rotates with the assembly (Figs 24, 27). <IMAGE>
