Abstract: The apparatus comprises a measuring cell (1) which consists of a measuring part (2) having a measuring electrode (26) and a reference electrode, and of a mixer part (3) for mixing the sample stream with a conditioner. The mixer part is formed by a Venturi meter (20), through which the sample stream flows, and in which a feed line for the conditioner ends in the region in front of its constriction (21). The conditioner is sucked into the Venturi meter by the sample stream and is mixed therewith in the expansion (22) following the constriction. As a result there is an intensive mixing of sample stream and conditioner without a special pump being necessary to convey the latter, and the desired pH value is set in the mixture in each case within a very short time. <IMAGE>

Filed: 1985-03-09
Abstract: The invention relates to a reactor for industrial plants, e.g. for an ammonia synthesis plant, comprising several catalyst beds in series charged by a radial gas flow. The object is to provide for a uniform gas flow through the catalyst bed along its entire height, otherwise different space velocities are experienced within the catalyst bed involving irregularities in the reaction. The problem is solved when the cross-section of the annular space for the effluent reaction gas flowing in axial direction is equal to or larger than the cross-section of the annular space for the influent fresh gas flowing in axial direction.

Abstract: The absorption of the thermal expansion of plastic sleeve tubes by a double-sealed expansion element which, in the expanded state, has a mechanical seal with respect to the sliding ring seal, allows the remote heating lines to be completely laid without compensation elements. After commissioning of the lines, the compensator, which is then double-sealed, can be welded. In this arrangement, all the elements of the compensation element are designed such that they conform to the strength requirements of the overall line and subsequent insulation with insulating foam is possible without any problems. <IMAGE>

Abstract: @ A multi-port valve uses a flexible sample tube to selectively intercept gases flowing from inlet ports into a common manifold space. The manifold space is placed under sufficient vacuum to insure that gas samples will be selectively received by the sample tube when the sample tube is placed in close proximity to the selected inlet port to be sampled. The sample tube is arranged so that gases to be sampled from the selected port wash over the entrance end of the sample tube so that contaminated or mixed gases from the manifold space are prevented from entering the sample tube. The sample tube is mounted to pivot inside a valve body and is moved by a sample tube guide which rotates inside the valve body to selectively align the sample tube with the inlet ports. The valve body may be sealed by a cover through which the valve guide is driven to rotate by a magnetic coupling, or by a bearing seal through which the sample tube guide projects. The sample guide may be rotated in a stepwise fashion by a stepper motor for slow collection rates, or may be rotated quickly by a motor for rapid sampling. Magnetic detectors or a shaft decoder may be used to monitor the position of the sample tube guide. The multi-port valve may be used in a system in which a measuring device such as a mass spectrometer and a data system are used.

Abstract: Fatty acid alkyl esters are produced by catalytic transesterification of natural fats and oils containing free fatty acids. In a preliminary esterifying step, the free fatty acids present are reacted with a C1-C4 alkanol (e.g., methanol) in the presence of an acidic esterification catalyst, at a temperature of about 50 DEG  to 120 DEG  C. and at substantially atmospheric pressure. The resulting reaction mixture is allowed to separate into two phases: (1) an alcohol phase containing the acidic esterification catalyst and part of the water of reaction and (2) an oil phase. These phases separately recovered. The oil phase is then extracted with an immiscible extractant, preferably comprising a mixture of glycerol and methanol, to remove residual water of reaction. In the final step the extracted oil phase is transesterified with a C1-C4 alkanol, e.g. methanol, in the presence of an aklali catalyst and at substantially atmospheric pressure.

Abstract: A cap and container especially suited for dispensing liquids has a cap which is accurately aligned upon closure. The container is closed by applying downward axial pressure to the cap, thereby forcing lugs in the cap to pass over a fastening means located on the neck of the container so that the cap is snapped on. Stop walls prevent any undesired cap rotation. Alternatively, the container is closed by twisting or rotating the cap with respect to the neck. The cap may also be twisted or snapped off. Modifications in the neck configuration make the cap irremovable.

Abstract: A digital filter (8) is provided between a tone signal generation circuit (1) which supplies a digital tone signal in accordance with a first sampling frequency and a sampling circuit (7) which resamples this digital tone signal in accordance with a second sampling frequency which is lower than the first sampling frequency. This digital filter (8) filters the input digital tone signal with such amplitude-frequency characteristics as to be able to substantially remove an aliasing noise produced due to the second sampling frequency (e.g., with low-pasa filter characteristics having a cut-off frequency which is 1/2 the second sampling frequency). This removes high frequency components producing an aliasing noise from the digital tone signal before it Is applied to the resampling circuit whereby generation of the aliasing noise in resampling is prevented. The resampling is performed for adapting the digital tone signal to an operation clock frequency of an effect imparting circuit (4) provided in a posterior stage for imparting, in digital, a tone effect such as a modulation effect to the digital tone signal.
