Title: Fibre-optical measuring equipment
Inventor: RULL HARTWIG DR
IPC: G01D5/26
Filed: 1981-12-14
Granted: 1987-07-02
Abstract: The fiber optical measuring device contains a fiber optical transmission line into whose input end are directed a first and a second light beam. Both light beams have wavelengths differing from each other. Associated with the output end of the transmission line is a mirror. This mirror passes the transmitted second light beam therethrough and reflects the transmitted first light beam back into the transmission line. Associated with the output end is also a sensor for measuring a physical parameter. This sensor receives the second light beam and returns a portion thereof back into the output end. This portion depends on the parameter to be measured. Arranged at the input end of the transmission line is an optical device which separates the reflected portion of the first light beam from the returned portion of the second light beam. A first optical detector transforms the first light beam portion into a first electric signal, and a second optical detector transforms the second light beam portion into a second electric signal. A signal processor determines the ratio between the second and the first electric signals. This ratio indicates the value of the physical parameter to be measured.

Patent DE-3381616-D1 (DE)
Inventor: WEISHAUPT R
IPC: C07G99/00
Filed: 1983-09-09
Granted: 1990-07-05
Abstract: A method of synthesizing and purifying a high molecular weight aggregate, derived from hematoporphyrin, said material being useful in the localization and treatment of tumors. The substance results from the hydrolysis of the reaction mixture of hematoporphyrin and acetic-sulfuric acids. The material is purified by cycling the crude product through a micro-porous membrane system in which exclusion of low molecular weight by-products is effected. The substance is tumor-selective and photosensitizing. It is retained in tumors longer than in normal tissues and fluoresces red to aid in diagnosis. Strong illumination of tumors retaining the substance results in necrosis, while normal tissues which have generally eliminated the drug remain unaffected. The high molecular weight aggregate has an empirical formula of approximately C68H70N8O11 (Na plus H)4.

Title: Apparatus for the injection moulding of disc records
Inventor: AMORY HENRI
IPC: B29C45/17
Filed: 1985-05-07
Granted: 1989-06-01
Abstract: Two matrices (10, 11), each bearing modulation to form a microgroove disc record, are fixed to half-moulds (4) by means of sleeves (23, 24) having first and second fixing flanges (41, 42) which extend into the gap between the matrices. One of the flanges (46) is an annular blade whose inner radial surface (47) defines the edge of a moulded disc and whose thickness is slightly less than that of the moulded disc. Formed integrally with, or attached to, the blade is a group of radially outwardly extending lugs (49) which are attached to the body of its associated sleeve 23. The other flange comprises a second group of lugs (42) mounted to the body of its associated sleeve (24) radially outward of the blade such that the second group of lugs (42) may lie in the spaces between the first mentioned group of lugs (49). The thickness of the lugs (42) of the second group determines the thickness of the disc and the thickness of the lugs of the first and second groups differs, to determine a gap for escape of air along the first flange (41). Spaces between the groups of the two interlaced lugs (49, 42) permit a controlled escape of air from the periphery of the record without the formation of peripheral flash.

Abstract: The invention relates to a retroviral vector capable of transducing and expressing genes in eucaryotic, particularly embryonic cells. This retroviral vector is derived from a retrovirus infectious for said cells, which DNA recombinant comprises the long terminal repeats (LTR) of the 5 min  and 3 min termini of the provirus, part of the first intron which contains the packaging signal of the corresponding retrovirus and, between said intron and the opposite LTR, a first promoter-enhancer region and a second eucaryotic promoter downstream and adjacent to the first promoter region, both of said promoters being selected among those which are recognized by the endogenous polymerases of said cells. Transformation of said cells with said retroviral vector, modified beforehand by said gene, i.e. the <<neo>> gene, by insertion thereof under the control of said second promoter, causes stable integration of said gene into said cells with the attendant transcription and, preferably, translation thereof.

Granted: 1994-07-21
Abstract: Collagen membranes with desired properties are prepared by using a variety of gel-forming techniques in combination with methods for converting the gels to solid forms. One technique involves compressing a gel matrix under constant pressure to form a fibre network which is dried; another involves disrupting and centrifuging a matrix, harmonizing the precipitate auto or paste and casting and drying the paste. The properties of these membranes or other solid forms may be further altered by cross-linking the collagen preparation either after formation of the membrane or gel, or most preferably by mixing cross-linked collagen with solubilized collagen in the original mixture used to create the gel.
