Abstract: Die Erfindung betrifft ein Verfahren zur Herstellung eines elektrischen Kontaktes zwischen einem normalleitenden Kontaktkörper und dem Endstück eines in-situ-geglühten Supraleiters aus einer intermetallischen Verbindung. Wird von der in-situ-Glühung ein entsprechendes Leitervorprodukt auf den Kontaktkörper aufgebracht, so kann bei der nachfolgenden Glühung ein reaktionsfähiges Element der herzustellenden supraleitenden Verbindung in das Material des Kontaktkörpers hineindiffundieren und so für eine Umsetzung zu der supraleitenden Verbindung fehlen. Die Folge ist eine verminderte Stromtragfähigkeit des Supraleiters. Gemäß der Erfindung ist deshalb vorgesehen, daß das entsprechende Endstück (19) des Leitervorproduktes (2) vor der Glühung auf einen Formkörper (7) aus einem hitzebeständigen, sich bei der Glühung mit den Elementen des Leitervorproduktes (2) nicht umsetzenden Material aufgebraucht wird und daß nach der Glühung der Formkörper (7) gegen einen Kontaktkörper (23) mit entsprechender Gestalt ausgetauscht wird. Mit dem Verfahren gemäß der Erfindung lassen sich insbesondere Kontakte für Hochfeldmagnete mit Supraleitern aus spröden intermetallischen Verbindungen wie z. B. Nb Sn oder V Ga herstellen.

Abstract: The mechanism is for maintaining balance in the pick-up of loads by hydraulic cranes or dredgers, and involves a hinged, suspended counterweight capable of balancing the supporting vessel in any position by displacement of the centre of gravity. The counterweight is also connected by rods to the front arm (4) of an articulated arm lifting mechanism (2). Via these rods (6) the centre of gravity is displaced a second time in order to balance the lifting mechanism. A final adjustment is made by the pressure in the articulated arm cylinder being transferred to an auxiliary cylinder which automatically then corrects the counterweight. The arrangement enables a 75 per cent saving in engine power for activating the crane.

Abstract: As a result of unretentive connections in sanitary blocks of domestic buildings, damage due to moisture frequently occurs on ceilings and walls. Moreover, manufacture of such sanitary blocks is very labour-intensive. These disadvantages are overcome by a specially designed wall covering element (1, 25, 35) which can be fixed, as a prefabricated building unit, to a carcass wall (13). This wall covering element can be used not only for sanitary blocks but also for swimming pools and facades. The wall covering element consists of a moisture-resistant supporting plate (2, 26), rigid per se, a heat and sound insulating layer (5) applied thereto, and a resilient levelling layer (6) arranged on the latter. The supporting plate (2, 26) is expediently provided on its free face with a bonded-on ceramic layer (4). To interconnect a plurality of wall covering elements (1, 25, 35), connecting members (7, 15, 16, 28 and 34), capable of insertion into the latter and at the same time having a fixing plate (8, 20 and 29) for attachment to the carcass wall (13) are used. <IMAGE>

Abstract: A porous implantable oral prosthesis which can be used to replicate and replace any hard tissue portion of the mouth such as bone and teeth is described. The prosthesis comprises sintered polymeric particles coated with a hydrophilic material. The polymeric particles vary in size so as to provide an area of relatively coarse porosity (2,12,22,32,42) where the prosthesis is intended to interface with bone tissue (6,16,26,38,48) and relatively fine porosity where it is intended to interface with soft tissue (7,17,27,39,47). A process for producing such prosthesis by filling a mold with appropriate molding compounds comprised of polymeric particles and a hydrophilic monomer, sintering the particles and polymerizing the monomer by dielectric heating, removing the sintered material from the cooled mold, and placing the prosthesis in a hot liquid to remove residues is described. An entire tooth, including a nonporous crown (4,14) may be produced. A process for producing a porous replica of a tooth root (1) suitable for implantation immediately after extraction of a tooth is disclosed. When extraction has taken place in the past and has resulted in the bone and gum receding, a porous implant (11,21) inserted in a newly drilled hole in the patient's jaw bone may be used. A central post (5,15) associated with the implant projecting above the gum may be used for attaching a denture, partial bridge or a crown. A porous implant (31,41 ) may be used for jaw bone replacement in order to improve the fitting of dentures.

Abstract: An optical system (60) is disclosed for use with a radiant energy receiver which provides high cold shield efficiency and is compact; further the optical system maintains focus with changes in temperature and wavelength without operator intervention. The optical system (60) has primary utility in the infrared region of the- spectrum and where a two dimensional array of detectors (106) senses the infrared radiant energy (56a-c) or flux from the scene of interest. The optical system (60) is comprised of a window (70) for environmental protection and two objective mirrors (82, 88) for folding and focusing the scene of interest on a first focal plane (90). Relay optical means (100), which may be comprised of one or more optical elements (134, 136, 138), relays and relocates the first focal plane (90) to a second focal plane (102) which is coincident with the surface of the two dimensional detector array (106); the relay optical means (100) also forms an exit pupil (118) (the image of the aperture stop) around which the aperture of a cold shield (114) is positioned to minimize extraneous radiant energy falling on the detector array (106). Using a positive and negative refractive lens (134, 136) and a judicious selection of materials allows the relay optical means (100) to automatically compensate for variation in its index of refraction as a function of temperature and wavelength.

Abstract: A method and apparatus for rapidly moving a reading beam of light radially relative to a rotating record disc, to impinge on a selected target track on the disc and recover information recorded on it. The apparatus first radially translates an optical system that directs the beam onto the disc at a relatively high speed until it is within a prescribed radial distance of the target track. Thereafter, an element of the optical system is controllably deflected such that the beam moves incrementally across a prescribed plurality of tracks during each disc revolution, until reaching the target track. The information recorded on each track includes a unique address signal, and movement of the beam relative to the disc is controlled according to the difference between the respective addresses of the track currently being scanned and the target track. If the apparatus fails to properly recover a track address signal, it estimates the address of the track currently being scanned, and updates its control of the beam's radial movement based on that estimate.
