摘要:
La présente invention concerne un échangeur de chaleur. Cet échangeur de chaleur comprend une première enceinte dans laquelle se trouve un sel fondu (5), en contact thermique avec une deuxième enceinte (4), au sommet de laquelle arrive un fluide caloporteur froid, et une conduite (7) placée dans cette deuxième enceinte (4), par laquelle sort le fluide caloporteur réchauffé. Cette deuxième enceinte (4) comporte un garnissage (11) permettant de réguler l'écoulement du fluide jusqu'au bas de la deuxième enceinte (4) et la vaporisation partielle du fluide caloporteur sous forme de petites bulles de gaz pouvant s'échapper par la conduite (7) au moyen des trous (10). Application à la climatisation de combinaison de plongeurs sous-marins.

An embodiment of a submersible warming garment comprises a closed fluid loop including a warming conduit disposed in thermal communication with a chamber containing a catalyst and a cooling conduit disposed within a wearable garment. A pump moves the fluid through the warming conduit, where heat is gained, to the cooling conduit, where heat is surrendered to a human wearing the garment, and back to the pump. An actuated valve on a container of fuel and an actuated valve on a container of oxygen are controlled using a controller to provide a combustible mixture into the chamber where the mixture reacts in the presence of a catalytic member to generate heat and combustion by-products. The combustion by-products, including carbon dioxide and water, are one of adsorbed and absorbed by a carbon dioxide scrubber and a reusable water storage medium. A fan moves the by-products into the scrubber and water storage medium.

Die Erfindung betrifft einen Kreislauf-Tauchgerät (Rebreather) mit eigenem Antriebssystem (34) für eine rationelle Fortbewegung eines Tauchers unter Wasser mit Möglichkeiten in verschiedenen Tiefenbereichen unterschiedlichen Atemgasgemische zu verwenden um den Tauchgang zu optimieren und die folgende Dekompressionszeit zu verkürzen. Ein derartiges Tauchgerät mit eigenem Antriebssystem (33,34) und Gasversorgung (9,10,55,56) mit unterschiedlichen Atemgasgemischen ist von großempraktischem Interesse. Es ermöglicht den Taucher nicht nur tief unter Wasser vorzudringen mit wenig Verlust von Kraft und Atemgas, sondern nach Tauchtiefe und Grundzeit die entsprechende Dekompressionszeit wesentlich zu verkürzen durch Gaswechsel von Inertgasen, wie Stickstoff, Argon, Helium, in unterschiedlicher Zusammensetzung mit Sauerstoff. Der Taucher hat auch die Möglichkeit sich unter Wasser schnell zu bewegen und unterschiedlichen Unterwasser-Beobachtungen oder Arbeiten durchzuführen. Solche Geräte sind umso notwendiger, wenn ein größerer Aktionsradius, umfangreiche Ausrüstung und längere Tauchzeit gebraucht werden.
摘要:
A personal temperature control system for sustaining normal body temperatures in environments with extreme temperatures including a first heat exchanger (10) adapted to be worn as a garment and a second heat exchanger (18) adapted to interact with a temperature source, the first and second heat exchangers being interconnected through a pump (26) and reservoir (28) unit. The first heat exchanger together with the pump and reservoir are portable and in one embodiment the second heat exchanger is constructed to be fully portable. Specific devices including automatic quick release couplings (24) interconnect the first heat exchanger to the second heat exchanger through the pump and reservoir. The fabrication of the first heat exchanger in helmet and vest portions is disclosed together with a control display unit housing (30) the pump and reservoir and including an adjustable flow valve (150) connected in parallel with the second heat exchanger. A preferred embodiment of the adjustable flow valve provides nonlinear change in rate of flow upon adjustment.

摘要:
Un appareil de chauffage de gaz pour plongeurs comprend une cartouche de chauffage electrique (1) qui est inseree de maniere interchangeable avec un ajustage serre dans un tuyau a ailettes (2) ayant une bride helicoidale externe (3). Le tuyau est entoure par un manteau (4) qui est relie a un capuchon (8) possedant une buse de sortie (9). Le capuchon (8) et le tuyau (2) sont introduits avec un jeu sensible dans un recipient a pression (5, 6, 10). Le recipient possede un couvercle d'extremite (6) au travers duquel s'etend la buse de capuchon (9). Le couvercle d'extremite (6) possede egalement une buse d'entree (7) de gaz froid, qui peut ainsi s'ecouler au travers de l'espace (12) entre le manteau (4) et la paroi du recipient (5) vers l'extremite du tuyau a l'oppose du capuchon (8) et depuis la le gaz s'ecoule dans un cheminement helicoidal au travers d'un troncon de canal defini par la bride (3) et le manteau (4) vers la buse de sortie (9) et il est rechauffe pendant son passage le long dudit cheminement. Le recipient comprend egalement un compartiment ouvrable ferme hermetiquement (19) dans lequel une connexion electrique entre la cartouche (1) et un cable d'alimentation de courant peut etre isolee hermetiquement de l'eau ambiante.
