Patent DE-3341876-A1 (DE)
Title: Coupling for connecting optical instruments
Inventor: SCHAUER HANS
IPC: G02B23/24
Filed: 1983-11-19
Abstract: The invention relates to a coupling for connecting an optical instrument such as a camera to another optical instrument, in particular a medical endoscope, which has an eyecup or the like. In order to achieve in this case that there is a non-positive and positive connection, and above all protection against twisting between the parts to be coupled, it is proposed according to the invention that the coupling contains a clamping element which consists of a ring having clamping fingers, which are adjoined axially thereto and embrace the eyecup of the endoscope or the like radially in an outwardly resilient fashion. In this case, actuation is performed by a clamping sleeve which can easily be displaced axially on the clamping element and can be clamped positively and non positively in the radial and axial directions. As a result, the connection between, for example, the camera and the medical endoscope continuously remains firm. It is also possible to incorporate in this coupling an axially adjustable alignment ring for the optics. A branched beam path for the co-observer can also be provided for application. Moreover, connection to a television camera having very small dimensions is preferred, no branched beam path being required for this purpose, because the image appears on the television screen and can be observed there satisfactorily even by a large number of persons.

Title: Semiconductor element
Inventor: KEMMER JOSEF DIPL PHYS DR
IPC: H01L29/93
Filed: 1984-06-08
Abstract: A semiconductor element is described, the capacitance of which is variable under voltage control. The semiconductor element exhibits a body of a first type of conductivity which exhibits in the area of its main surfaces regions to which a voltage which depletes the semiconductor body of majority carriers is in each case applied in the reverse direction with respect to the body. To change the capacitance of the semiconductor element under voltage control, the control voltage is applied between one region and the body and the voltage applied to the other region and the body is selected to be of such a maximum value that at the maximum value of the control voltage, the semiconductor body is completely depleted of majority carriers. The particular advantage in the semiconductor element according to the invention is that the magnitude of the change in capacitance can be varied by varying the second applied voltage with the same variation of the control voltage.

Title: Contact-making device between an apparatus and a consumable article
Inventor: ROSELT JUERGEN
IPC: H01R12/71
Filed: 1984-08-20
Abstract: A contact-making device between an apparatus which is intended for multiple use and a consumable article which can be used one or a few times, for example between a holder for pyrotechnic display ammunition and a multiple ammunition plate. The contact device on the side of the consumable article is arranged on a board in such a manner that it forms a free contact surface facing away from the board, for example as a solder eye consisting of soft material. The associated contact device of the apparatus has opposite it an abutment which can move relative to the contact device in such a manner that the board, with the solder eye, can be clamped between the contact device of the apparatus and its abutment in order to produce the contact force. When this contact force is applied, sharp edges in the contact surface of the contact device on the apparatus side break through a possible oxide or dirt layer on the contact surface of the consumable article. A large number of contact devices of the apparatus are enclosed in a foam-rubber sheet which, in the contact position of the arrangement, rests on the board in a sealing manner. The parts of the contact-making device on the apparatus side are connected to the apparatus in a moving manner by means of devices for connection of the consumable article, so that, when the apparatus is closed after insertion of the article, they move automatically into the contact position.

Patent DE-3500466-A1 (DE)
Title: Shaft seal
Inventor: WARSCHKE WERNER
IPC: F16J15/40
Filed: 1985-01-09
Abstract: The object of the invention is to seal off an opening for the passage of a shaft in a maching having a rotor for the treatment of fluid media. Between the working space of the housing and of the shaft bearing, the housing surface opposite the rotor is, according to the invention, designed as a cavity in the form of an inner spherical sector and the rotor, which is secured on the shaft and rotates with it and which has the same spherical curvature but is in the form of the surface of a spherical sector, is arranged with the minimum possible clearance relative to the housing surface, without metallic friction, the interspace which forms between the housing and the rotor thus representing a parallel channel. As a result, a sufficiently strong flow pressure to prevent the fluid to be treated from forcing its way out of the working space, beyond the channel and to the opening for the passage of the shaft is built up in the said channel during the movement of the rotor, even at the minimum speed of rotation.

Title: Highly transparent heat-insulation coating which appears neutral when looked through and when viewed from the outside
Inventor: GLAESER HANS JOACHIM DR
IPC: B32B17/10
Filed: 1985-02-05
Abstract: The invention relates to a highly transparent heat-insulation coating (9) which appears neutral when looked through and when viewed from the outside, for a substrate (6) of transparent material, such as glass sheets and plastic films, and which can be used, in particular, for insulating glass sheets. The coating is built up from a layer system having the layer sequence metal oxide/silver/metal oxide, where the metal oxide (1, 5) is preferably bismuth oxide. The silver (3) is admixed with at least one substance of high melting point, for example tungsten, rhenium, tantalum, osmium, niobium, molybdenum and/or iridium, preferably tungsten in an amount of 0.4%. This prevents the formation of islands and droplets which has hitherto occurred on application of pure silver as a thin layer; the light absorption and thus the optical properties are thus greatly improved.   <IMAGE>

Patent DE-3524444-A1 (DE)
Title: Tube arrangement for heat exchangers or the like
Inventor: MANCIN BERTI PEDRO
IPC: F28F1/02
Filed: 1985-07-09
Abstract: A description is given of a tube arrangement for heat exchangers or the like which has an elliptical or rectangular cross-section and transverse connectors which are installed in the interior at a spacing from one another over the tube length and in each case form an angle whose apex lies in the central plane of the tube arrangement. In the event of thermal expansion of the tube arrangement, the angle of the transverse connectors increases up to 180 DEG , so that the now rigid transverse connectors prevent the tube arrangement from retracting to its original initial circumference. Owing to the irreversible expansion, the cooling pins located between the tube arrangements are mechanically clamped, so that it is possible to eliminate welding operations or the like for mounting them.
