Abstract: FLOW DUCT OF AN AXIAL-FLOW HYDRAULIC MACHINE                  A B S T A C T      The flow duct of an axial-flow hydraulic machine is defined by a casing of which the internal surface is of a complex geometrical form. The casing defines an inflow or inlet portion, a portion accommodating the blase system, ad-joining the inflow portion, and an outflow or outlet portion directly adjoining the portion accommodating the blade system, downstream thereof.  The inner surface defining the inflow por-tion is made in the form of at least one truncated rectangular pyramid wit the greater cross-section facing the inlet, the cross-section perpendicular to the axis of the flow duct being of substantially rectangular form with rounded-off corners, the rounding radius of these corners increasing to the value of the radius of the circle defining the cross-section of the inlet of the portion accommodating the  blade system.  The last---mentioned portion has circular form of its cross-sections per-pendicular to the axis of the flow duct. The internal surface defining the outflow portion is made in the form of as at least one truncated rectangular pyramid its the greater cross--section facing the outlet, the cross-sections perpendicular to the axis of the flow duct being of a substantially rectangu-lar form with rounded-off corners with the rounding radius.     decreasing lengthwise of the outflow portion from the value of the radius of the circle defining the outlet cross-section of the portion accommodating the blade system.    An axial-flow turbine of the capsule type with the flow duct according to the present invention and an adequately de-veloped blade system with 16 wicket gates of a height equalling 0.4 of the runner diameter, the latter being of a four-blade type, 7.5 m in diameter, operated t a 35 feed head, offers as much as 94.3% efficiency.

Abstract: \          METHOD AND APPARATUS FOR COLD LIDDING   CONTAINERS WITH ELASTOMERIC FILM      Abstract Of The Disclosure A method and apparatus for cold lidding open-top containers with roll-stock elastomeric film by holding a web of the film in air-tight relation across the bottom of a lidding chamber and about its periphery, evacuating the lidding chamber to stretch the web thereinto, inserting the top of the container into the lidding chamber, and releasing the stretched web over the top of the container whereby the inherent restorative characteristic of the web causes it to quickly contract, i.e. "snap" onto the periphery of the container to form a dynamic seal.  The removal of the lidded container from the apparatus causes the container to be moved against a tripper plate to ready the apparatus for lidding the next container.  The minimum recovery factor of the stretched film web should be about 85% of its original size.

Abstract: CHARGE CONTROL SYSTEM FOR XEROGRAPHIC MACHINES     ABSTRACT OF THE DISCLOSURE    Apparatus for controlling the charge level on the photoconductive surface of a reproduction machine to enhance imaging.  A corona generator is used to initially charge the photoconductive surface following which the charge is examined and compared with a preselected reference charge.  Where an overcharge is found, a lamp, the illumination intensity of which is matched to the degree of overcharge, is actuated to reduce the charge level on the photoconductive surface to substantially the same as the reference charge.   Where an undercharge is found, a supplemental charging device is actuated to the degree necessary to bring the charge level up to the reference charge.  The discharge lamp may be combined with the corona generator or be separate therefrom.    An alternate embodiment has a lamp providing a fixed illumination output is provided with a liquid crystal inter-posed between the photoconductive surface and the lamp to control the degree of illumination to which the photoconductive surface is subjected.

Abstract: La présente invention est un jeu de société à caractère stratégique dont le déroulement dépend entièrement des décisions prises par les joueurs, sans l'intervention du hasard.  Le jeu symbolise un conflit entre deux empires: les Blancs et les Noirs.  Dans le palais du Prince des Blancs se trouve la Princesse des Noirs et dans le palais du Prince des Noirs se trouve la Princesse des Blancs au moment où les armées des Empereurs et des Impératrices des deux camps sont sur le champ de bataille pour se battre. Les Empereurs et les Impératrices décident, que celui sera le vainqueur qui réussira le premier, soit à faire sortir la Princesse du palais du Prince adverse avant que celui-ci puisse l'attra per, soit à faire attra per la Princesse adverse par le Prince dans le palais de celui-ci avant qu'elle puisse s'échapper.  Les Empereurs, en se déplaçant, dirigent les mouvements des Princes, et les Impératrices, en se déplaçant, dirigent les mouvements des Princesses en projetant leurs propres mouvements du champ de bataille dans les palais.  Les armées facilitent cet-te action en entravant les mouvements de l'Empereur et de l'Impératrice adverses qui restent intouchables, et en éliminant le potentiel de l'armée adverse.  Le jeu est joué sur un plan qui est divisé en trois parties distinctes (le champ de bataille et les deux palais) par deux joueurs qui effectuent alternativement chacun un mouvement avec leurs pièces. La présente invention est basée sur l'idée de projections de mouvements de pièces spécifiques d'une partie du plan du jeu dans deux autres parties distinctes figurant sur le plan du jeu.  Le jeu est conçu de manière que les projections susmentionnées lui donnent un caractère particulier et le rendent ainsi distinct des autres jeux de société de ce genre. Le jeu, ayant un vaste ensemble de possibilités de combinaisons stratégiques, développe le sens de la logique et peut, de ce fait, être considéré comme un jeu éducatif.

Abstract: EXTRACTION METHOD OF TRITIUM     ABSTRACT OF THE DISCLOSURE           An extraction method of a high purity tritium gas from tritium-containing heavy water is disclosed.  Tritium-containing heavy water is led from a heavy water source into an exchange reaction column wherein the heavy water is brought into contact with a tritium-containing heavy hydrogen to thereby transfer tritium in the heavy hydrogen into the heavy water by way of the exchange reaction to obtain a tritium-enriched heavy water. The resulting tritium-enriched heavy water is then led to a heavy hydrogen gas generator such as an electrolytic cell to generate a tritium-enriched heavy hydrogen, a part of which is recycl-ed to the exchange reaction column and the remaining part thereof is led into a hot-wire type thermal diffusion column cascade to enrich tritium. The thus enriched tritium gas is withdrawn from the thermal diffusion column cascade. The tritium-depleted heavy hydrogen withdrawn from the exchange reaction column is burnt to produce a tritium-depleted heavy water which is then recycled to both the heavy water source and the exchange reaction column.
