Title: Device for carrying out photometric measurements on liquids
Inventor: BAUMERT DIETER DIPL PHYS
IPC: G01N21/85
Filed: 1988-08-02
Abstract: The invention relates to a device for carrying out photoelectric measurements on liquids for analytical purposes in laboratories, for supervisory tasks and the like, the photometric measuring signal representing a quantitative or qualitative statement about the sample to be assessed. It can be used both for working on samples in a continuously flowing stream and, by means of additional devices, for working on samples discontinuously and discretely. To generate a thin homogeneous measuring liquid beam and to carry out the measurements, the device is so designed that a beam tube is arranged, at least with its exit opening, and a light guide running at least partially in the beam tube, on the one hand, and a first radiation detector, on the other hand, are arranged axially with respect to one another on an ideal longitudinal axis at a distance forming a measuring volume, and a second radiation detector is directed at an adjustable angle towards the ideal longitudinal axis and a rinsing nozzle is directed towards an entry surface of the first radiation detector facing the light guide.

Title: Catheter
Inventor: HESSEL STEFAN DR
IPC: G02B6/24
Filed: 1988-10-06
Abstract: In the catheters of the main application P 3717525 in which a laser light bundle (40) is guided obliquely into an optical fibre (2) such that it emerges in the form of an envelope of a cone in a laterally directed manner at the distal catheter end with circumferential radiation characteristics, a radiation absorption surface (48) is arranged, according to the invention, in the output angle region (46) of the circumferentially radiated light bundle. This radiation absorption surface is used to heat up an application member (6) located at the distal catheter end, and independently of the first circumferential laser light bundle a second, ablative laser light bundle (32) is coupled into the proximal light guide front face (16) such that it is emitted in a manner directed towards a light guide channel (10) extending to the catheter tip at the distal light guide end (36) separately from the first light bundle and with essentially axial radiation characteristics, and is radiated to the outside, as a result of which two different, mutually complementing laser light effects, namely the cauterisation effect of the heated application member, on the one hand, and the direct irradiating effect of the outwardly emitted light bundle, on the other hand, can be simply combined without exchange of the catheter and without enlargement of the catheter diameter in each case independently meterable for effective vascular recanalisation. <IMAGE>

Title: Microbe-repelling piping
IPC: F24D17/00
Filed: 1989-03-03
Abstract: The invention relates to certain gaps in hygiene safety which can possibly result from the fact that downstream of sterilisation equipment, such as for example ultraviolet sterilisation equipment which naturally does not have any subsequent bactericidal action in the following piping, subsequent microbial contamination can form in the downstream piping systems by bacterial colonies forming from the permissible residual microbes (colony forming unit, CFU) on the walls, from which individual microbes or a multiplicity of microbes can detach and thus the water which was previously sufficiently reduced in microbial count is again microbially contaminated. In accordance with the inventive concept, downstream of the sterilisation apparatus lacking subsequent microbicidal effect, only those pipe systems are used, the water-wetted surfaces of which do not permit colonisation by microorganisms, either because the pH counteracts colonisation or other material properties prevent this. This final piping leaving sterilisation equipment is generally only furnished with simple fittings such as shut-off valves, mixer heads, shower sprays etc which, without great effort, can be, for example, internally silvered which, as experience has shown, prevents colonisation by microorganisms, especially bacteria, so that the piping according to the invention in connection with such fittings overall excludes with sufficient reliability the subsequent microbial contamination which is particularly feared in hot water systems. In this case [lacuna] is ... Original abstract incomplete.
