Abstract: This invention is a bileaflet heart valve (10) comprising an annular base (12) and pivoting leaflets (14). Each leaflet (14) is 'free-floating' within recesses (32) without fixed rotational axis, to increase translational movement and redistribute stresses. Each recess (32) fluidly communicates with a groove extending at least partially around the inner surface (30) of the annular base (12), and flow is directed through the recesses (32) at different angles during antegrade circulation, retrograde circulation, and valve closure. A recess entrance angle to each of the recesses preferably being less than about 35° and the pivoting mechanism within the recess (32) including first and second fulcrum edges (164, 166) of each leaflet (14) is shiftingly engaged with side surfaces of the respective recess (32). The leaflets have a beveled bottom surface (74) having two separate planor surfaces which lie at an angle to one another. In preferred embodiments, a central region of each leaflet is spaced apart from the annular base (12) when the leaflet (14) is in a fully closed position to minimize cavitation.

Abstract: PCT No. PCT/DE96/02011 Sec. 371 Date Jun. 18, 1998 Sec. 102(e) Date Jun. 18, 1998 PCT Filed Oct. 23, 1996 PCT Pub. No. WO97/15976 PCT Pub. Date May 1, 1997A back-up device includes at least one back-up battery, in particular a rechargeable battery which can be charged via the power supply, and a control unit. The control unit connects the back-up battery when the actual value of the DC voltage is less than a predefined minimum value, generates a predefined back-up time period and disconnects the back-up battery again, cyclically, after this time period has elapsed. The device has the advantage that the return of the output DC voltage of the power supply can be identified effectively without major complexity. The loads continue to be supplied both in the event of a failure of the supplying input voltage and in the event of a failure of the power supply, since the output DC voltage, which is essential for the loads, of the power supply is monitored. The device can be connected additively downstream of a power supply, without any intervention in its design being necessary. The device has the further advantage that it automatically connects the battery as a back-up, even in the event of dips in the output DC voltage caused by short-circuits, as soon as the load voltage falls below the minimum value. Thus, the device allows a virtually continuous transfer and back-up of the output DC voltage in a multiplicity of fault situations.

Abstract: The present invention involves a composition and method for the determination of enzymatic activity or enzyme substrate concentration in a fluid test sample in which the enzyme catalyzes a reaction in a reagent system to provide a detectable response indicative of the concentration of the enzyme or enzyme substrate in the test sample. A measured amount of a protease capable of eliminating the enzymatic activity is included in the reagent composition, so that when a measured amount of test sample is treated, the reaction producing the detectable response will have a definite end point. The invention is particularly useful in conjunction with the determination of leucocytes in urine wherein the leukocytes are lysed to release their human leucocyte elastase which hydrolyzes a chromogenic ester to provide a phenol which then reacts with a diazonium salt to form a colored azo dye.

Abstract: The present invention is directed to an optical device that is switchable
between an on and an off state in which an optical cavity is the basis for the
contrast between the on and the off states. The optical cavity is incorporated
into devices such as character and text displays, shelf price tags, etc. Devices
with the optical cavity provide advantages over devices that do not have an
optical cavity. For example, Displays made from electrochromic devices with
an optical cavity are easier to read than displays without the optical cavity.
The electrochromic device is formed on a glass substrate with a reflective
metal layer formed thereon. A transparent electrode is formed over the
reflective metal substrate. A layer of electrochromic material is then formed
over the transparent electrode. Electrolyte is placed in contact with the
electrochromic material. A counter electrode is in contact with the
electrolyte. The counter electrode provides a reservoir of metal ions that
changes the color of the electrochromic material in response to the
application of a voltage to the device. A second transparent electrode is in
contact with the counter electrode. A transparent substrate is placed over
the second transparent electrode. The display is viewed through the
transparent substrate. It is advantageous if the combined thickness of the
first transparent electrode and the electrochromic layer is about 550 Å to 
about 1400 Å. The first transparent electrode layer has a thickness of about
300 Å to about 600 Å. The thickness of the electrochromic layer is about 250
Å to about 800 Å.

Abstract: Des procédés connus de ce type ne peuvent pas donner entière satisfaction aussi bien en ce qui concerne le degré d'efficacité qu'en ce qui concerne l'utilité technique. Pour améliorer ces facteurs, il est donc proposé que le flux de matière (7) divisé soit d'abord soumis à un mouvement vertical et que le champ magnétique (tambour magnétique 4) situé en-dessous se déplace dans le sens horizontal, de sorte que ledit flux de matière exécute d'abord, sous l'influence du champ magnétique, une chute libre, les parties ou les particules présentant une conductibilité électrique  kappa  plus élevée étant accélérées plus fortement dans le sens horizontal et les parties ou particules présentant une densité  rho  plus faible étant accélérées plus lentement dans le sens vertical, de sorte que les parties ou particules présentant le plus grand facteur de séparation  kappa / rho  sont déviées les premières, et de la façon la plus forte, de l'axe de chute, dans le sens horizontal, et que le flux de matière est fractionné en conséquence. Le dispositif pour séparateur à courant de Foucault à créer par la mise en oeuvre du procédé doit permettre une séparation de particules électroconductrices en fonction du facteur de séparation  kappa / rho  de la matière. A cet effet, le dispositif est conçu de sorte que l'accélération des particules et leur déviation du flux de matière se fassent en fonction du facteur de séparation.
