Patent EP-0008148-A1 (EP)
Inventor: DIRKSING ROBERT STANLEY
IPC: G05D11/03
Filed: 1979-08-02
Abstract: A self-priming passive dosing dispenser for issuing, beginning with the first flush, a quantity of a toilet tank additive solution into a toilet tank as the water is draining therefrom while the toilet is flushing. A preferred dispenser comprises a reservoir for containing a quantity of a toilet tank additive type product and in which reservoir a solid type product can be dissolved to form a product solution. Structure is provided for flooding the reservoir through the discharge standpipe upon initial immersion of the dispenser into the toilet tank water to ensure first flush dispensing of product solution. In steady state operation, while the water in the toilet tank is receding from about the dispenser, a predetermined dose-volume of toilet tank water is vacuum-transferred from a measuring cavity located within said dispenser into said reservoir through an inlet conduit, and a substantially equal dose-volume of the product solution is dispensed through a discharge standpipe. The dispenser may further comprise an internal baffle to precipitate mixing and agitation inside the dispenser which promote dissolution. Upon reaching steady state operation, the dispenser provides an air-lock when immersed in a full toilet tank which air-lock isolates the product and product solution from toilet tank water which surrounds the dispenser during quiescent periods. Plural product co-dispensers which embody the present invention are also disclosed.

Abstract: Capsule a avaler pour obtenir des echantillons de fluides gastriques et/ou intestinaux, la capsule definissant une chambre de reception (18) d'un fluide ayant un orifice d'entree (17) qui est normalement ferme et isole de l'exterieur de la capsule avec des moyens d'obstruction consistant en une masse (21) dont les proprietes changent au contact des fluides appropries presents dans l'appareil digestif, ce qui provoque la communication a travers l'orifice d'entree (17) entre l'exterieur de la capsule et la chambre de reception (18) ou un echantillon de fluide est aspire. Dans la chambre se trouvent des moyens de fermeture (9, 12, 14) normalement maintenus en position permettant l'ecoulement par une masse (28) qui colle les parties necessaires des moyens de fermeture ensemble de telle maniere qu'elles ne puissent pas bouger, de sorte que l'action des moyens de fermeture soit neutralisee. Cette masse (28) est sensible au contact des fluides appropries du tube digestif pour permettre aux moyens de fermeture (9, 12, 14) de fermer la chambre (18) de maniere a ce que l'echantillon soit protege contre la contamination pendant la suite de son parcours a travers le reste de l'appareil digestif. En utilisant une masse differente (21, 28) qui se dissoudra dans le suc gastrique ou qui ne se dissoudra qu'apres contact avec le contenue alcalin du grale intestin, la capsule peut etre utilisee pour obtenir un echantillon de suc gastrique ou de suc intestinal. Un indicateur d'HC1 libre, ou alternativement d'acide lactique, peut etre contenu dans la chambre (18) de la capsule; cet indicateur reagit en presence d'HC1 libre, ou d'acide lactique dans l'echantillon pour changer la couleur de l'echantillon, ce qui permet de le voir a travers une partie transparente de la paroi de la capsule.

Abstract: Un appareil cryogenique et une methode mise en oeuvre par l'appareil consiste a ameliorer le trajet d'ecoulement afin d'eliminer les impuretes introduites par un courant d'appoint d'un liquide cryogenique. En reduisant la temperature du courant dans un passage d'ecoulement d'echange thermique, les impuretes sont susceptibles de se solidifier et de boucher l'echangeur de chaleur. Selon l'invention, le courant d'appoint (14) est dirige sur des moyens (26, 42) d'absorption des impuretes qui sont susceptibles de se solidifier dans l'echangeur (30, 40) avant la combinaison du courant d'appoint (14) avec le courant d'alimentation principal (12). L'utilisation principale est l'application a un appareil cryogenique de liquefaction d'helium refroidi a une temperature inferieure au point de solidification de contaminants gazeux comprenant le gaz carbonique et l'air.

Abstract: A conveyor device comprising a movable carrier (1) which is provided with two freely-rotatable rollers (3, 4 and 41, 42 respectively), an endless belt (51) or cord (5) which traverses a return loop over each of the two rollers of the carrier, the said return loops are opposite in direction to each other, traverse a straight trajectory (6, 7, 8, 9) parallel to the direction of movement of the carrier and are connected with each other via two rotational paths of which the straight trajectories form a part. The endless belt or cord is provided with driving means (13, 44) on one of the rotational paths and, at the other rotational path it is provided with disconnectable means (15, 53) for stopping the belt or cord in that rotational path.

Abstract: A thoracic drainage unit for removal of fluids from the thoracic cavity of a patient and/or to assist a patient in breathing comprises a collection chamber for receiving the fluids from the patient and an underwater seal located beween the collection chamber and the patient. The underwater seal prevents pressure being applied to the thoracic cavity or back flow to that cavity. The water or other liquid for the seal is provided with the collection chamber as a complete unit ready for use. A collapsible bottle has a breakable neck that is readily broken by the user, whereupon the bottle is collapsed to force the liquid therein to create the liquid seal. A means is provided to prevent the liquid from re-entering the bottle as it re-expands so that the precise needed volume of liquid is retained to create the seal. Also, the water seal is located in a particular location, and the underwater seal chamber is designed such that seal integrity is not lost upon tipping over the drainage unit; and the seal remains viable upon re-righting the unit. The underwater seal chamber is designed to allow viewing of an air leak from the patient, even foaming or opaque fluid. Critical measurement area for collected fluids is provided, and hangers that can be used also asfloor stands are included with unit.

Abstract: The roller body consists of annular discs (3 or 5) lined up on an axle (1) and consisting of porous material. The material of the roller body is compressed by uniform axial compression applied from the end faces. Since, before the compression, a larger volume of material is provided in the region near the axle than in the region distant from the axle, during compression there is a higher material density in the region near the axle than in the region distant from the axle. A squeezing roller constructed in this way has not only good wiping-off and squeezing properties with regard to the fluid, but also a long service life. <IMAGE>

Abstract: Method for the reconstitution, by filtering, of an analog signal, from a pseudo-analog signal obtained by a double, analog to digital, digital to analog conversions of the analog signal, with processing of the digital signal. In greater detail, the pseudo-analog signal, obtained by double analog to digital, digital to analog conversion of an analog signal, is applied to an active filter the impedance of which is controlled by the absolute derivative of the positive value of the pseudo-analog signal. The derivative is obtained by a circuit comprising an RC filter receiving the pseudo-analog signal and a memory controlling the value of the impedance of the filter. The invention has particular application to the restitution of graphic or iconographic documents which have been previously digitally encoded.
