Title: Method and apparatus for detecting cataractogenesis.
Inventor: BENEDEK GEORGE B
IPC: A61B3/10
Filed: 1988-08-31
Abstract: A method is disclosed for using quasielastic light scattering to determine the degree of cataractogenesis of a lens in vivo. By collecting and analyzing light (18) scattered from the lens, it is possible, using the autocorrelation function or the power spectrum (160), to separate the fluctuations into two components: one caused by fast diffusing proteins and one caused by slow diffusing protein aggregates. This data may be applied to an experimentally determined and theoretically deduced universal curve in order to determine quantitatively (170) the degree of cataractogenesis at that particular location in the lens.

Abstract: Dans un assemblage à engrenage différentiel du type comprenant des engrenages à vis sans fin ou hélicoïdaux montés sur des axes croisés ne s'intersectant pas, deux arbres d'entraînement (12, 14) sont reçus dans des alésages (10) formés dans les côtés d'un carter de différentiel (4), et des engrenages latéraux ou à vis sans fin alignés axialement (18, 30) sont couplés à chaque extrémité d'arbre pour s'engrener avec des engrenages de transfert de couple dans ledit carter. L'un des engrenages latéraux (30) est pourvu d'une bride dirigée vers l'extérieur (36) qui chevauche une bride dirigée vers l'intérieur (42) associée au carter pour maintenir les faces extrêmes des engrenages latéraux (18, 30) sans qu'elles se touchent pour empêcher des forces de poussée axiale développées dans un engrenage latéral (30) de passer vers l'autre (18) et pour éliminer les forces de frottement au niveau de l'interface des interfaces latéraux, réduisant ainsi les différences de rapport de sollicitation associé aux directions opposées de différentiation sans réduire de manière importante le rapport de sollicitation global de l'ensemble.

Abstract: Method of pouring a metal, in particular steel, from a casting ladle (24) into a tundish (1) or the like by means of a choking slide gate nozzle or stopper end, by which the ferrostatic height of the metal in the tundish (1) is regulated to match a set withdrawal speed of the cast strand. The regulation takes place here with a so-called tendency recognition, i.e. taking into consideration the change of the amount of metal in the tundish (1). Furthermore, with each reversal of correcting variable or motion at the casting ladle closure an error value (alpha) resulting from the system tolerances is added to the correcting variable (Y). The method is also applicable in the case of nozzle closures of tundishes (1), and to be precise in relation to the bath level in the mould (28).

Abstract: A tumble dryer for small articles of clothing having no motor or heater utilizes the output of a hair dryer to both rotate a drum containing the articles of clothing and to dry the articles. Turbine blades mounted on the periphery of the drum slowly rotate the drum to prevent uneven drying of the clothing in the warm air output from the dryer. A tray mounted beneath the drum can be used to catch water dripping from the clothing. Removing the tray allows the hot air to escape from the bottom of the unit for warming the room or drying hands. The tumble dryer and its associated hair dryer are preferably wall-mounted.

Abstract: A water-based photopolymerizable resin composition is disclosed which is suitable for the preparation of a relief printing plate by the photolithographic techniques. The inventive composition, which basically comprises a water-­soluble polymer, e.g., poly(vinyl alcohol), a photopolymer­izable monomer and a photopolymerization initiator, is characterized in that at least a part of the photopolymeriz­able monomer is N-tetrahydrofurfuryloxymethyl acrylamide or N-tetrahydrofurfuryloxymethyl methacrylamide. By virtue of this unique ingredient in the composition, the printing plate prepared from the inventive composition is imparted with improved fidelity of pattern reproduction and durabi­lity in printing as a consequence of increased hardness and pliability to be freed from the drawback of crack formation in printing even on a cylinder of small diameter under a cold and low-humidity condition.

Abstract: The system is designed to be mounted in a helmet. It makes use of an afocal assembly, with a first (4) and a second (5) parabolic mirror, disposed downstream of a collimating objective lens (2) which supplies a collimated radiation. The first mirror (4) is totally reflecting and the second mirror (5) semitransparent in order to transmit simultaneously, by reflection, the collimated radiation and, by transparency, for example the view of the external scene. These two mirrors are integrated at the ends of a plate (10) having two parallel faces (10AV, 10AR). The collimated radiation penetrates into the plate through one of the parallel faces (10AR), is reflected on the first mirror (4), undergoes a succession of total reflections on the parallel faces (10AV, 10AR) and then is reflected on the second mirror (5) before emerging from the plate (10), again through one of the two faces (10AR). The invention is applicable, in particular, to the construction of helmet displays for aircraft pilots. <IMAGE>

Abstract: Un film polymère microporeux très poreux comprend un halopolymère dans lequel les unités à répétition sont -(CnH2n)- et -(CmX2m)- dans lesquelles chaque X représente indépendamment du fluor ou du chlore, les valeurs de n et m étant supérieures à un et inférieures à six. Le film est le résultat premièrement d'un traitement par fusion d'un mélange du halopolymère, de plus de 150 parties en poids d'un sel extractible et de pas plus de 80 parties en poids d'un polymère extractible pour 100 parties en poids de halopolymère, ledit polymère extractible n'étant pas mélangé complètement et de manière homogène avec le halopolymère, et étant moins visqueux que le halopolymère lorsqu'ils sont tous les deux fusionnés, de sorte que les surfaces du film résultant du traitement par fusion soient riches en polymère extractible, et deuxièmement de l'extraction d'au moins un peu du sel extractible pour rendre le film poreux, et de l'extraction d'au moins un peu dudit polymère pour donner au film une porosité de surface. Ledit film a une porosité supérieure à 50 % en volume et habituellement de l'ordre de 60 à 70 %. On peut utiliser ledit film comme séparation d'une cellule électrochimique par exemple d'une batterie ayant une anode au lithium et un électrolyte de chlorure de thionyle. On a en outre découvert que l'on peut obtenir des porosités élevées et de bonnes propriétés électriques, par l'utilisation comme polymère extractible d'un matériau ayant une masse moléculaire inférieure à un million, par exemple un oxyde de polyéthylène d'une masse moléculaire d'environ 100 000.

Title: Removing hazardous contaminants from water.
Inventor: LAMARRE BRUCE L
IPC: B01D3/22
Filed: 1989-10-12
Abstract: A method for removing hazardous contaminants such as radon gas and volatile synthetic organic chemicals from domestic water supplies uses a perforated, horizontally-oriented tray which is baffled to define a curved (e.g., serpentine, spiral) liquid flow path. Contaminated water is distributed upon a portion of the tray and flows as directed by the baffles to a downcomer and into a storage tank. Air is blown into the storage tank, which is located below the perforated tray, and up through the perforations. The forced air causes the water flowing across the tray to froth, and evaporates the contaminants out of the frothing water. The forced air, carrying the volatilized contaminants, is then vented outside the home. <IMAGE>

Abstract: A description is given of a reversible storage device for agents, which consists of a storage core (1), an intermediate storage device (2), a catalyst (3) and a protective sheath (4). Upon opening of the protective sheath, the stored agent is heated in the catalyst layer owing to the entry of oxygen which then takes place. The storage device manages without a source of external heat, because the bond energy in the intermediate storage device is much lower than that of the main storage device, so that the intermediate storage device serves as a starter for the reaction. 
<??>Applications of the storage device according to the invention are envisaged, in particular, for heating foodstuffs, including beverages, for heat treatment of patients in a state of shock, and as rapidly responding hydrogen storage devices for dispensing hydrogen without the supply of extraneous energy.
