Abstract: Cartilage tissue and implants comprising cartilage tissue are produced in vitro starting from cells having the ability to form an extracellular cartilage matrix. Such cells are brought into a cell space (1) and are left in this cell space for producing an extracellular cartilage matrix. The cells are brought into the cell space to have a cell density of ca. 5×107 to 109 cells per cm3 of cell space. The cell space (1) is at least partly separated from a culture medium space (2) surrounding the cell space by a semi-permeable wall (3) or by an open-pore wall acting as convection barrier. The open-pore wall can be designed as a plate (7) made of a bone substitute material and constituting the bottom of the cell space (1).

Abstract: The apparatus for the production of endochondral or osteochondral bores comprises a combination of a substantially hollow cylindrical sleeve (10), of which one end is formed as a circular cutting edge (11), with a flat borer (20) which is rotatably and axially displaceably arranged in the sleeve (10). Through pressing in of the cutting edge (11) into the tissue, advantageously only into the cartilage tissue, a tissue column is punched out which then is cut away and removed through screwing in of the flat borer (20). In this the boring is done up to the depth of the cutting edge (11) or deeper.

Abstract: In the method of a photo-oxidative treatment of tissue containing collagen tissue, the tissue is pre-treated with an aqueous conditioning solution prior to an irradiation with light. In this pre-treatment the tissue permeable to the solution is loaded with a dye contained in the solution, in particular with methylene blue. This dye, activated by light, catalyzes photo-oxidative reactions. In accordance with the invention a substance is added to the conditioning solution, the refractive index of which is greater than that of water. As a result of this additive, the tissue containing collagen assumes a greater transparency for light during the pre-treatment.

Abstract: A defined determination of the field of view observed through a surgical microscope is made. To achieve this determination, the relative current position of the plane of the field of view to the position of an object detail of interest is detected in a sighting method with the aid of a position detection system operating according to the laser triangulation principle. As soon as the plane of the field of view and the object detail are coincident, then with the aid of detected optical system data, the position of the object detail with reference to the surgical microscope is determined and, with the detected coordinates of the surgical microscope, the position of the field of view is determined in space. The position detecting system required for this purpose operates on an optical basis and can be integrated into the optics of the surgical microscope.

Abstract: In radio transmission systems having a number of radio channels available for transmission, it is necessary to recognize a transmission channel as idle. One known way of doing this is to measure the field strength on the transmission channel and carry out a threshold decision. As soon as the field strength in a transmission channel is below a preset value, this transmission channel is recognized as idle. In measuring field strength, the field strength is averaged over the entire bandwidth of the transmission channel. As a result, a transmission channel that experiences interference from the signals on its adjacent channels may not be recognized as idle, although the adjacent-channel interference has little effect on the transmission quality. The new method makes it possible to recognize the signal present in a transmission channel by means of numerous narrowband field strength measurements.

Abstract: An endoscopic instrument includes an elongate shaft with an optical system arranged therein. The shaft is closed off at least its distal end by a window which is firmly and tightly connected to the shaft. The closure window is constructed of spinel or yttrium-aluminum-garnet. The spinel may be cubic monocrystalline spinel or polycrystalline spinel, and the yttrium-aluminum-garnet may be undoped or neodymium-doped. Similar closure windows of the same materials may be provided at other openings in the endoscope shaft, such as a proximal end ocular or eyepiece or a lateral light guide window. The closure window may optionally be in the form of a lens to function as part of the optical system.

Abstract: The invention relates to a kick starting means for change gears, in particular for retrofitting motorcycles of the company Harley-Davidson, U.S.A., with the name "Big Twin", a cubic capacity of about 1340 cm.sup.3 and a five-speed change gear, which has been built since 1980. A kick starting axis 1 is located outside of a gear shaft level 2 formed by a gear drive axle 3 and a gear driven axle 4. This arrangement makes it possible that for retrofitting the aforementioned motorcycles with kick starting means, no modification of the original exhaust pipe assembly is necessary. (FIG.

Abstract: An apparatus for conveying a textile product from an upstream to a downstream station, especially for delivery into a package, has an endless conveyor belt driven by a drive and a pressure unit, the textile product being conveyed while held in a gripped manner between conveyor belt and pressure unit. To achieve rapid conveyance of the textile product without thereby impairing it, it is proposed that the conveyor belt be configured as a first telescoping belt, the front end of which, facing the downstream station, can move back and forth in the direction of the downstream station while the pressure unit follows this motion synchronously; and that the drive be controlled so that the belt of the telescoping belt is not driven as the front end moves back from the downstream station, and thereby rolls off the textile product.

Abstract: The method of comminution of soft tissue (4) from animal or human bodies is performed by a mechanism (10) which exhibits a supply vessel (1), cutter member (2) and collector (3) and forms a closure impermeable to germs against the environment The tissue is removed from the body in a sterile environment, and filled into the supply vessel of the opened mechanism. After the supply vessel has been assembled together with the clutter member and the collector into a mechanism ready for operation, by the employment of pressure-exerting means, preferably compressed gas (11'), the tissue is delivered from the supply vessel into the collector, the tissue being comminuted at the same time by the cutter member.
