Patent EP-0355966-A1 (EP)
Inventor: SOLT GEORGE STEFAN
IPC: B01J49/00
Filed: 1989-07-07
Abstract: The present invention relates to a method of reducing the concentration of contaminant ions, preferably nitrate ions, in impure water. The method comprises steps of: a) passing the impure water through an ion exchange resin to substitute regenerant ions from the resin for dissolved contaminant ions; b) passing a relatively dilute aqueous solution of wash-out ions through said resin to substitute wash-out ions for contaminant ions bound to the resin and; 
c) passing a relatively concentrated aqueous solution of regenerant ions through said resin to substitute regenerant ions for wash-out ions bound to the resin. The affinity of the resin to wash-out ions diminishes from being greater than that for contaminant and regenerant ions when exposed to a relatively dilute ionic solution to being less than that for said contaminant and regenerant ions when exposed to a relatively concentrated ionic solution. The method allows simplified ion exchange apparatus to be utilised, since the raw water, wash-out solution and   regenerant solution may all be passed through the ion exchange resin in the same direction.

IPC: A47C3/30
Filed: 1989-09-25
Abstract: The invention relates to a control device for a gas spring which can be locked as desired by displacement of a sliding control finger. Two axially elongated, diametrically opposed windows (14), at least one of which is larger at the end nearest to the gas spring, pass through a tubular connector (1) coaxial with the control finger (6). A lever (2) which has thinner parts (25, 26) flanking a wide part (24) engages in these windows. Devices (7) are provided so that, after mounting on the gas spring, the wide part (24) is unable to reach the wide section of the window, thus preventing the lever from being dislodged. The edges of the windows (14) form bearing points for the pivoting movement of the leaver and the actuation of the control finger (6).

Title: Apparatus for reducing noise resulting from hydraulic pressure surges
Inventor: SUFFRIDGE ROBERT L
IPC: F15B21/04
Filed: 1989-01-11
Abstract: A method and apparatus for reducing the intensity of the sound that accompanies a rapid decompression in a pressurized hydraulic system. The apparatus includes a reduced area valve that interconnects the high pressure system with a low pressure system, with the valve connected with a tubular muffler so that high pressure fluid is initially released through the valve and into the muffler. The muffler includes a plurality of spaced apertures that face a rigid structural surface so that the high pressure fluid passing through the muffler issues from the several apertures and impinges on the rigid structure to dissipate the pressure shock accompanying decompression, and thereby modulate the intensity of the sound of decompression.

Abstract: On effectue la séparation du sang en extrayant et en réinfusant alternativement le sang d'un donneur au moyen d'une seule aiguille, tout en séparant en même temps et en continu le sang extrait en ses composants. Un harnais qui peut être appliqué à un instrument d'hémaphérèse comprend un réservoir à double compartiment. Un premier compartiment stocke le sang pendant l'extraction afin de le fournir au séparateur pendant la réinfusion. Le deuxième compartiment stocke des cellules concentrées pendant le prélèvement afin de les retourner au donneur pendant la réinfusion. Les cycles de prélèvement et de réinfusion alternent rapidement pour éviter la coagulation du sang dans des parties non traitées avec un anticoagulant des tubulures du harnais situées entre l'aiguille de vénoponction et la connexion en Y avec le conduit d'anticoagulant.

Abstract: 1,1-Dichloro-1-fluoroethane, 1-chloro-1,1-difluoro­ethane and hydrogen fluoride are separated from their liquid mixtures, such as liquid mixtures resulting from the hydrofluorination of 1,1,1-trichloroethane or vinylidene chloride. 1,1-Dichloro-1-fluoroethane and 1-chloro-1,1-­difluoroethane are first separated by distillation into their respective mixtures with hydrogen fluoride, which are thereafter subjected to parallel phase separations result­ing in two hydrogen fluoride-enriched liquid phases, a 1-­chloro-1,1-difluoroethane-enriched liquid phase and a 1,1-­dichloro-1-fluoroethane-enriched liquid phase. 1-Chloro-­1,1-difluoroethane and 1,1-dichloro-1-fluoroethane are purified from the respective halohydrocarbon-enriched liquid phases by distillation. The hydrogen fluoride-­enriched stream generated from the phase separation of the hydrogen fluoride/1,1-dichloro-1-fluoroethane mixture is recycled to the hydrofluorination reaction mixture.

Abstract: A conveyor is presented which consists of individual carriers which can be driven in pushing or pulling mode and can be coupled together to form a train. The overall length of this conveyor is absolutely constant both in pulling and pushing mode. For this purpose, the individual carriers are connected to one another via elastic coupling elements (1) both in a positively locking and in a frictionally locking fashion so that a spatially articulated arrangement which is free of play is constructed. Instead of the elastic coupling elements (1), cardan joints (4) can be provided which are prestressed via springs (5a, 5c) which exert a compressive force on the joint part via a ball (6a, 6c) or a bolt (6a, 6c) so that the cardan joint (4) itself is absolutely free of play. <IMAGE>
