Abstract: A disinfecting and cleaning agent connection device for devices with a chamber for the holding or transport of fluids has a connection line that connects the fluid chamber with a disinfecting or cleaning agent container. The connection device has a connection line, a buffer chamber, a sealing element in the upper section of the buffer chamber connecting it with the fluid chamber, a channel which opens into the bottom section of the buffer chamber and has a siphon-type section whose end lies lower than the bottom of the buffer chamber, and a fluid sensor in the buffer chamber which is lower than the upper section of the siphon area and higher than the channel opening into the buffer chamber. The disinfecting and cleaning agent connection device can be used in conjunction with medical devices such as a dialysis machine and a reverse osmosis machine.

Abstract: The invention relates to a disposable element for a medical treatment device, especially a hemodialysis device. The inventive disposable element comprises a film bag filled with the dialysis liquid that consists of two superimposed flat films or a tubular film with connections for supplying and discharging the liquid. The film bag or the tubular film, in the condition ready for usage, is closed with a first weld on the top end and with a second weld on the lower end and is folded several times parallel to the longitudinal axis that is vertical in the condition ready for usage. The film bag is inserted in a receiving unit that is configured as a shaping dish that has a middle cylindrical section followed by an upper or lower convex section. The inventive disposable element, when combined with the receiving unit, unfolds more easily when being filled and has a lesser tendency to form creases.

Abstract: A selectively herbicidal composition for controlling grasses and weeds in crops of useful plats, comprising a) a herbicidally effective mixture of MCPA, bromoxynil and a compound of formula (I) wherein the substituents are as defined in claim 1 and b) an amount, effective for herbicide antagonism, of a compound of formula (II) wherein the substituents are as defined in claim 1.

Abstract: The invention relates to a welding boat for a pouch having a center part and two prolongations extending, starting from this, in opposite directions and tapering acutely, which is provided, on the one hand, with an opening for the filling of the pouch with a substance in manufacture and, on the other hand, with inlets and outlets for the actual use of the pouch. In accordance with the invention, the center part is substantially filled by an opening with a lumen which is as large as possible and preferably circular and the side edges of the side prolongations contact the opening tangentially.

Abstract: The invention refers to a disinfecting and cleaning agent connection device for devices with a chamber for the holding or transport of fluids with a connection line for connection of the fluid chamber with a disinfecting or cleaning agent container. In accordance with the invention, the disinfecting agent connection device includes a connection line with the following features: a buffer chamber, a sealing element in the upper section of the buffer chamber connecting it with the fluid chamber, a channel which opens into the bottom section of the buffer chamber and has a siphon-type section whose end lies lower than the bottom of the buffer chamber and a fluid sensor in the buffer chamber which is lower than the upper section of the siphon area and higher than the channel opening into the buffer chamber.

Abstract: A method and apparatus for the preparation of solutions to be manufactured from at least two concentrates and a solvent. After placing of two concentrate holders into associated recipients, both concentrate holders are connected using a single connector having two connection states. In a first connection state, solvent flows to the first concentrate holder, with the solution being led into a collection holder and, after the flushing of the concentrate from the first concentrate holder, the connector moves to a second connection state in which an automatic connecting of the second concentrate holder takes place, whereupon solvent flows through the second concentrate holder and the solution is likewise supplied to the collection holder.

Abstract: The invention relates to a disposable element for a medical treatment device, especially a hemodialysis device. The inventive disposable element comprises a film bag filled with the dialysis liquid that consists of two superimposed flat films or a tubular film with connections for supplying and discharging the liquid. The film bag or the tubular film, in the condition ready for usage, is closed with a first weld on the top end and with a second weld (4, 5) on the lower end and is folded several times parallel to the longitudinal axis that is vertical in the condition ready for usage. The film bag is inserted in a receiving unit that is configured as a shaping dish (15) that has a middle cylindrical section (16) followed by an upper or lower convex section (17, 18). The inventive disposable element, when combined with the receiving unit, unfolds more easily when being filled and has a lesser tendency to form creases.

Abstract: A method and apparatus for the preparation of solutions to be manufactured from at least two concentrates and a solvent. First and second concentrate holders are connected to a solvent source by respective feed lines and to a collection holder by respective discharge lines. The solvent source is connected to the first concentrate holder when a connector is in a first position and to the second concentrate holder when the connector is in a second position. Solvent flows through the first concentrate holder and the solution is led into the collection holder and, after the flushing of the concentrate from the first concentrate holder, the second concentrate holder is automatically connected through movement of the connector from the first to the second position, whereupon solvent flows through the second concentrate holder and the solution is likewise supplied to the collection holder.
