Abstract: An apparatus and method for the sampling and quantitative, IR-spectroscopic determination of impurities in hygroscopic liquids. The apparatus includes a stainless steel tube having a straight bore, a first end, and a second end. A first flange attachment is located at the first end of the stainless steel tube, and a second flange attachment is located at the second end of the stainless steel tube. First and second calcium fluoride plates are also located at the first and second ends of the steel tube, respectively. The first and second plates are oriented parallel to each other and perpendicular to the axis of the stainless steel tube. First and second outer flanges hold respective of the first and second plates in place at the first and second ends of the tube, respectively, and the first and second outer flanges are mechanically fixed to the first and second flange attachments, respectively. At least one seal separates the first plate from the first flange attachment and the first outer flange.

Abstract: A delivery line for conveying viscous or pasty material to be filled into a food can or the like from a conveyor pump to a filling machine, having a delivery path developed in the form of a trombone tube with two sections extending parallel to each other and a U-shaped arch, the legs of which cooperate telescopically with the two sections. A pneumatic or hydraulic piston unit is provided to act on the U-shaped arch against the pressure of the filling material in the direction toward a shortening of the delivery path.

Abstract: An apportioning unit for the filling of food cans with a viscous, pasty or lumpy material, having at least one cylinder unit which is moved past a sealing plate, a lower part which is developed with a first passage hole for the filling material and is provided with an annular key arranged concentrically to the first passage hole, and an upper part which bears the sealing plate and is developed with a second passage hole for the filling material. The upper part has an annular groove which receives the annular key and is arranged concentrically to the second passage hole. The depth of the annular groove is greater than the height of the annular key and the annular groove receives an elastic annular tube.
