Abstract: Dans un échangeur de chaleur à plaques constitué d'un empilement de plaques dont chacune comporte une partie centrale servant au transfert de la chaleur et un bord externe, les parties des plaques servant au transfert de la chaleur délimitent entre elles des espaces dans lesquels circulent les deux fluides d'échange de chaleur. Les bords externes des plaques sont pliés, toutes les plaques de l'empilement ayant leur bord externe plié dans la même direction et étant liées les unes aux autres par un matériau de liaison (30) qui est liquide au départ. Chaque plaque est constituée de deux parois et de deux fines plaques de transfert de chaleur (15, 16) de la même taille qui sont pressées sensiblement à la même forme et qui sont serrées l'une contre l'autre mais qui permettent à un fluide d'échange de chaleur passant dans un trou ménagé dans une plaque de transfert de chaleur de passer entre les plaques de transfert de chaleur jusqu'au bord externe de la plaque. En outre, les plaques de transfert de chaleur (15, 16) de chaque plaque comportent des rebords (29) situés extérieurement au bord de la plaque qui est relié à une partie correspondante d'un autre bord de plaque adjacente au moyen dudit matériau de liaison (30), ces rebords (29) étant pliés de telle manière que deux rebords (29) adjacents de deux plaques adjacentes sont espacés l'un par rapport à l'autre.

Abstract: On décrit un système de propulsion à piston double destiné à équiper un lance-projectiles du type sans recul et à masse/contremasse, dans lequel deux pistons cylindriques creux (22, 23) sont disposés dos-à-dos et possèdent des extrémités externes ouvertes et des extrémités internes fermées. Les extrémités internes ouvertes sont reliées par un moyen de connexion périphérique frangible, de sorte que les pistons constituent une enceinte dans laquelle est logée la charge propulsive (34). Au moment de son utilisation, le système est disposé de manière à pouvoir glisser à l'intérieur du tube de lancement (1) à l'extrémité ouverte du lance-projectiles, en son point médian. La mise à feu de la charge propulsive entraîne une accumulation de gaz de propulsion à l'intérieur de l'enceinte. Lorsque la pression du gaz atteint un seuil prédéterminé le moyen de connexion se rompt sous la tension, et les pistons (22, 23) sont propulsés dans des directions opposées. Les forces de traction et de compression auxquelles sont soumis les pistons (22, 23) pendant la mise à feu de l'engin sont considérablement réduites par rapport à celles d'autres systèmes connus, ce qui permet d'utiliser des pistons (22, 23) de faibles poids.

Abstract: Using this device, an electrical cable can be separated and stripped to different lengths, with a minimum time consumption, without the separating and stripping tool having to be replaced when the stripping length and/or cable cross-section are changed. For this purpose, in each case two stripping blades (45) are arranged in two blade holders (42, 43), at a specific, fixed distance (D) from the separating blade (44). The stripping blades (45) are shortened with respect to the separating blades (44) by an amount (K), in such a manner that only the cable (6) is separated during a first part of the operating movement. The pulling-off drive pulls the cable ends back from the separation point to the desired stripping length, whereupon the insulation is cut into during a second part of the operating movement, and the scrap insulation is pulled off during a further retraction movement of the cable ends, with the stripping blades (45) closed. …<IMAGE>…

IPC: A01N1/02
Filed: 1992-10-14
Abstract: The invention relates to a perfusion apparatus (1) for isolated organs (2), which apparatus comprises at least one reservoir (3) for the perfusate, and also a pump (4) which draws the perfusate from the reservoir (3) by suction and pumps it into the isolated organ (2). With known perfusion apparatuses of this type, only measurements under so-called constant flow conditions can be carried out, since only the flow through the isolated organ (2) can be adjusted via the delivery rate of the pump (4). The resulting pressure depends on the characteristics of the organ (2). According to the invention, the perfusion apparatus is developed in such a way that both constant flow and constant pressure measurements are possible in each pressure range of physiological interest. For this purpose, a control line (8) branches from a line (6) downstream of the pump (4), against the end (9) of which control line (8) a closure part is pressed sealingly with a defined force. When a specific pressure in the line (8) is exceeded, this closure part falls back and this permits the passage of perfusate from the end (9) of the line (8). In a preferred embodiment, the closure part is an elastic membrane (10) behind which there is a hollow space (15) whose internal pressure produces the defined force on the membrane (10). The emerging perfusate can be returned to the reservoir (3) via a return line (14). <IMAGE>

Inventor: VON WEDEL WEDIGO
IPC: B01D53/94
Filed: 1992-10-23
Abstract: A process is described for the removal of nitrogen oxides from waste gases with the recovery of nitric acid or a nitrate solution. The waste gas is reacted with hydrogen peroxide in an amount appropriate to the desired degree of removal of nitrogen oxides, on a catalyst, at a temperature of less than 800 DEG  C., preferably in the range of 20 DEG  to 100 DEG  C., to give the valuable product, nitric acid or a nitrate solution. This may be done in accordance with the invention by bringing the hydrogen peroxide as a solution, i.e., in the liquid phase, into contact with the catalyst through which the waste gas is flowing. The reaction product is either utilized in a gaseous form or processed to nitric acid or a nitrate solution. Alternatively, the hydrogen peroxide may be introduced in a gaseous form, using a honeycombed catalyst, and wherein the hydrogen peroxide is present in at least one half of the stoichiometrically determined amount. Regardless of whether the hydrogen peroxide is introduced in a liquid or vapor form, the resulting nitric acid solution may be scrubbed, preferably with a nitrate salt solution, to provide the concentrated product.

Abstract: The invention provides a wavelength division multiplexer and a wavelength division demultiplexer by combining a wavelength-selective mode converter (3) with a wavelength-independent mode splitter (5). The demultiplexer comprises a monomodal input channel (1), an adapter (2) to the bimodal input of a 100%TX₀₀→TY₀₁(λ₁) mode converter (3), a bimodal junction channel (4), and a mode splitter (5) having a first output channel (6) and a second output channel (7), both monomodal, the first output channel (6) having a higher propagation constant than the second. A λ₁ component, which propagates with a polarisation TX (TE or TM) in an input signal S i1 (λ₁,λ₂,λ₃,--), will, after conversion in the converter (3), propagate in the intermediate channel (4), in the first-order guided mode having the polarisation TY (TE or TM), and subsequently leave the splitter via output channel (7). The remainder of the input signal is not affected by the converter, therefore remains in the zero-order mode in the intermediate channel (4), and will leave the splitter (5) via output channel (6). The multiplexer operates in the opposite direction. 
Advantages: Completely producible in integrated form, no fabrication steps of a different type required other than for the fabrication of the connecting optical waveguides.
