Patent EP-0328755-B1 (EP)
Title: Acceleration device at a compressed-air brake operating indirectly
IPC: B60T15/42
Filed: 1988-12-05
Granted: 1991-09-04
Abstract: The acceleration apparatus for connection with a pilot operated compressed-air brake comprises a tap-off valve which vents the main air line or conduit at the beginning of the braking procedure. This tap-off valve is opened by an actuator or actuating mechanism via a disengageable intermediary member. By employing a rotationally symmetrical plunger or push rod which is pivoted into the operative position thereof by a spring and deflected by an interrupter piston, the construction of the disengageable intermediary member can be substantially simplified. The plunger or push rod possesses at the one end thereof a cam or pin and a substantially conical surface.

Title: Device to accelerate bodies, in particular a movable aircraft catapult
IPC: B64F1/06
Filed: 1988-11-22
Granted: 1991-06-19
Abstract: In order to accelerate bodies along a guide track, a traction cable has been wound onto a roll at the end of the track. During decoupling, damage has occurred to the cable and to the environment in the region of the rotating cable. The device according to the invention serves, in particular, for catapult starting missiles (2). A winding drum (7') driven by hydraulic machines (7) is arranged below the location of the maximum track speed (V0) of the missile (2) and conveys the latter over the longitudinal track (1) to its lift-off speed. In this arrangement, the flat belt (8) connected to a travelling or transport carriage (22) reverses the direction of rotation (in D2) at the winding drum (7'), so that the travelling carriage (22) is braked on the shortest path. The device can be mounted on a light truck (10) and can be operated electrohydraulically by the vehicle battery. <IMAGE>

Abstract: A method of structurally modifying a silica monomode optical fibre (4) by launching optical power into the fibre (4) from a Nd:YAG laser operating at 1.064um and raising the temperature of a portion of the fibre (4) by bringing a metal film (12) into contact with a polished half-coupler block (6) to absorb energy from the laser (2). A structural modification of the fibre is initiated which propagates towards the laser (2) sustained by the optical power. It provides a means of decommissioning an optical fibre. The modified optical fibre (4) has regular periodic damage sites which can be used to form a diffraction grating. The method may also be used as an optical power limiter to protect optical networks from too high optical power inputs.

Abstract: Des oxydes de cuivre supraconducteurs de la structure perovskite sont modifiés pour avoir une occupation mêlée d'un site de cations, augmentant ainsi les limites de champ critique et/ou de courant critique. L'occupation mêlée peut se manifester par une résistivité accrue à mesure que le matériau supraconducteur retourne à un état non supraconducteur. Un avantage significatif, au moins pour des compositions préférées, provient du fait que la température critique est sensiblement inchangée par rapport au matériau prototype.

Title: Process and apparatus for making a non-elastic, impervious and flexible pressure belt, particularly for the wet press of a paper-making machine
IPC: D21F3/02
Filed: 1989-01-09
Granted: 1992-05-20
Abstract: Such press bands have, at least on their outer side facing the fibre web or the felt or felts, cavities and/or depressions for the removal of liquid which are produced by pouring a free-flowing mixture of a pre-polymer onto a continuous reinforcing woven belt and bonding it to the belt. Since the outer side of a press band coated in this way is smooth while the inner side of the band possesses the desired cavities and/or depressions for the removal of liquid, in order that the press band can be used in a wet press it must, after removal from the casting mould, first be inverted, a procedure which, especially in the case of small band diameters, is very difficult and requires a great deal of effort. 
<??>The invention avoids this disadvantage by arranging that, in order to manufacture the press band, the reinforcing woven band is led round one of at least two rolls which are arranged at distance in parallel one above the other or one beside the other and is coated, by means of at least one nozzle, on the outer side of the band or the inner side of the band or on both sides of the band with the free-flowing pre- polymer mixture.

Abstract: Cette invention concerne des couvercles distributeurs du type à va-et-vient. Les dispositifs de l'art antérieur ont une capacité de débit limitée et ne peuvent pas obtenir la capacité de vaporisation à haute pression ni la capacité directionnelle du courant de décharge. La présente invention palie les insuffisances de l'art antérieur par la mise au point d'un couvercle distributeur (11) pour un récipient (15). Le couvercle est du type comportant un bec mobile (21) monté sur un ajutage doté de passages de sortie (31). Le bec est mobile entre une position dans laquelle il bloque l'écoulement par les passages de sortie, et une autre position dans laquelle il permet l'écoulement par lesdits passages de sortie. L'amélioration met en oeuvre la formation supplémentaire d'un ou de plusieurs passages de décharge dans l'ajutage, lesquels ne sont pas régulés par le bec. Ces passages de décharge supplémentaires peuvent être du type créant un courant de décharge en angle, un courant de décharge à haute pression, une vaporisation mécaniquement fractionnée ou un écoulement de décharge à volume élevé. On peut prévoir un élément de fermeture séparé (43) pour les passages de décharge supplémenatires.

Abstract: A new class of composites results from a matrix of fibers, such as fibers of carbon, alumina, ceramics, and aluminosilicates, interwined in a network of fused metal fibers. The composites can be fabricated to have varying surface area, void volume, and pore size while maintaining high electrical conductivity. Composites are readily prepared from a preform of a dispersion of the metal fibers, other fibers, and an organic binder such as cellulose, by heating the preform at a temperature sufficient to fuse the metal fibers and to volatilize at least 90% of the binder. Where a carbon fiber is used, the metal fibers are fused at a temperature causing a loss of less than about 25%, and usually under 15%, by weight of carbon fiber.

Abstract: In infrared emitters, whose resistance wire is located in a sheathing tube of quartz glass or fused silica, radiant losses can be reduced by means of a reflection layer, for example of gold, located on the sheathing tube.

The protective coating can be produced by using thermally decomposable organic compounds of zirconium, silicon and/or tin.
