Filed: 1990-08-30
Granted: 1993-10-13
Abstract: La valve d'arrêt (10) à pression différentielle comprend un alésage étagé (14) présentant des sections de diamètres large (16) et étroit (18). La section de diamètre étroit (18) communique avec des premier (20), second (22) et troisième (24) orifices et la section de diamètre large (16) est divisée en deux chambres (50, 60) par une extrémité large (42) d'un élément de valve (40, 140, 240). Ledit élément de valve (40, 140, 240) comprend un passage traversant central (48, 148, 248), lequel communique avec la première chambre (50) située entre l'extrémité large (42) de l'élément de valve (40, 140, 240) et la section de diamètre large (16) de l'alésage étagé (14). La seconde chambre (60) est définie entre l'extrémité large (42) de l'élément de valve (40) et un épaulement (17) disposé entre les sections de diamètres large (16) et étroit (18) de l'alésage (40). La seconde chambre (60) communique avec un quatrième orifice (70) et renferme un élément résilient (80), lequel sollicite ledit élément de valve (40, 140, 240) à l'opposé du premier orifice (20). Un différentiel de pression existant dans l'élément de valve (40, 140, 240) entraîne ce dernier (40, 140, 240) à faire la navette et à comprimer ledit élément résilient (80) de sorte qu'une extrémité étroite (44, 144, 244) dudit élément de valve (40, 140, 240) vient au contact d'une extrémité de l'alésage (14) ou de l'insert (28, 90, 190, 228) de sorte que le premier orifice (20) est isolé des second (22) et troisième (24) orifices.

Abstract: The invention concerns processes for making a dental prosthesis or the base therefor. The base is ground from a block of synthetic material in accordance with the shape and contours of the oral cavity which may be obtained by using an impression or by optical means or by a combination of both. An impression requires the use of a model also obtained by suitably milling an original impression according to the shape and contours. The block of synthetic material used as the blank and a workpiece holder are constructed in such a way that the block can be fitted in only one position of the workpiece holder.

Abstract: The invention relates to a rack installation with storage containers arranged in the compartments of a rack, and a rack-tending unit which can be displaced in front of said containers and has at least one load table with a device for the storing and retrieving of storage containers. To design a rack installation in such a way that a positionally reliable transfer of the storage containers is made possible with little effort and expense, it is proposed that each storage container (3) has at both sides of its end face (3a) facing the rack-tending unit (4) one open slot guide (12) each for a driver (10) which projects from an endless driver traction element (9) guided around deflection wheels (8), whose mutual spacing Z is at least as great as the depth of insertion of the storage containers (3) into the compartments (2) of the rack (1). <IMAGE>

Abstract: The present apparatus for measuring blood flow comprises at least three electrodes, namely a measurement electrode (11), a reference electrode (15) and an active indifferent electrode (29), which are introduced into a specific tissue area (10). The signals from the measurement electrode and the reference electrode run through supply lines (12, 17) to a current-insulated and voltage-insulated differential amplifier (13) whose output is connected to an evaluation circuit (21) which controls display instruments (22, 23). An essential feature for the accuracy of the measurement of the present measuring apparatus is a negative feedback of external interference fields which couple interference potentials into the tissue (10) and into screens (25, 26, 27). The evaluation circuit (21) is expediently connected to further probes (33). <IMAGE>

Abstract: A grid correction circuit for a television receiver includes a first memory for storing correction values for correcting the deflection current of the television receiver. A second memory perodically provides a test signal to a correction coil to correct the deflection of the television receiver. A switch periodically selectively connects the first memory to the correction coil and a correction current flows through the correction coil. The switch also periodically connects the second memory to the correction coil and a test current flows through the correction coil. An impedance is responsive to the correction coil and produces a correction voltage and a test voltage in response to the correction current and the test current respectively. A comparator receives the test voltage and compares the test voltage to a reference voltage and provides an output voltage having a first level when the test voltage is below the reference voltage and a second level when the test voltage is above the reference voltage. A processor receives the output voltage and changes the correction voltage to incrementally reciprocate above and below the reference voltage by a preslected increment to maintain the correction voltage at substantially the same level as the reference voltage over a long time period.

Abstract: Improvements in piston-based ventilator design and operation are described. In one aspect, individual compensation of force dissipation within the gas delivery system is effected, so that the desired gas pressure is delivered to the patient airway without the necessity for monitoring the actual pressure and using it as feedback. In another aspect, a piston (14) is dimensioned slightly less than the chamber wall (12) of the pump to define a gap (18) through which an acceptable amount of gas may leak but which eliminates the need for a physical seal, thereby minimizing the frictional resistance within the pump. <MATH>

Abstract: The invention provides a method and apparatus for reconstituting beverages wherein superheated reconstituting liquid and beverage concentrate are delivered into a mixing chamber having an adjustable volume. The mixing chamber is the volume between two coaxially arranged tapered elements which are disposed one inside of the other. Final beverage product emanates from an aperture in the tip of the outer tapered element. At least one tapered element can be displaced in the longitudinal direction so that the volume of the mixing chamber decreases and approaches zero as the tapered elements are moved closer together. Thus, when the system is shutdown the volume of the mixing chamber is allowed to approach zero so that very little product is susceptible to degradation in the mixing chamber due to prolonged exposure to high temperatures during a shutdown. The reduced volume mixing chamber may be flushed with reconstituting liquid. In addition, the temperature of the mixing chamber can be controlled during a shutdown by adjusting the temperature of water contained within the walls of the tapered elements.
