Abstract: A method for selective detection of cyanide in a sample comprises determining a color change of a corrinoid compound caused upon contact with the sample. A high detection sensitivity and selectivity are achieved by having the corrinoid compound adsorbed on a solid phase. This general principle is applied in a kit for selective detection of cyanide and to uses thereof. One application consists in a device for removing hydrogen cyanide from a gaseous phase, e.g. tobacco smoke.

Abstract: A method of recovering inert gas used during a filling process for pressurizing containers which are to be filled with a liquid. The method includes the steps of expelling the air found in the container, and pressurizing the container, with a mixture of air and heavy inert gas; filling the container with the liquid and thus expelling the pressurizing gas mixture; centrally collecting the expelled mixture from a plurality of containers and conveying the mixture to at least one accumulator; subjecting the pressurizing gas mixture in the at least one accumulator to at least one gravity effect for partially separating off the lighter gas components and producing a mixture of predominantly inert gas; adding additional inert gas to a mixture of predominantly inert gas; and returning the resulting mixture to the filling process, at least as a pressurizing gas mixture, for use with subsequent containers which are to be filled.

Abstract: A method of cleaning bottle filling devices after bottle breakage in filling stations circulating in bottle filling machines, especially counterpressure filling machines. That filling station in which the bottle breakage has occurred is freed of glass fragments by spraying liquid thereagainst, while continuing with the machine rotation and still during the same circulation. At least during the first machine circulation subsequent to the bottle breakage and the liquid spraying, the filling device is rinsed with the liquid supplied to the bottle to be filled. After discharge from the machine circulation, the filled bottle is separated from the filled bottles of the remaining filling stations.
