Abstract: A pressure regulator employing a hollow bellows containing a precise amount of gas which provides the reference pressure source for the regulator. The bellows is mounted in one chamber of the regulator housing while a valve element is mounted in a second chamber. One end of the element extends through a port interconnecting the two chambers and is connected to the bellows. An inlet port in the housing communicates with the chamber containing the valve element while an outlet port provides communication between the bellows chamber and the exterior of the housing. As pressure increases at the outlet port, the bellows compresses causing the valve element to close the port interconnecting the two chambers within the housing.

Abstract translation: 一种采用中空波纹管的压力调节器，其中包含精确量的气体，为调节器提供参考压力源。 波纹管安装在调节器壳体的一个室中，而阀元件安装在第二室中。 元件的一端通过连接两个腔室的端口延伸并连接到波纹管。 壳体中的入口与容纳阀元件的腔室连通，而出口端口提供波纹管室与壳体外部之间的连通。 当出口处的压力增加时，波纹管压缩，使得阀元件关闭连接壳体内的两个腔室的端口。

Abstract: A MODULAR CHEMICAL ANALYSER SYSTEM PROVIDES FOR THE ANALYSIS OF A WIDE RANGE OF CHEMICAL PRODUCTS IN DIVERSE SERIALIZED REPETITIVE AUTOMATED PROCESSES. TYPICALLY, A SOLID TABLET SAMPLE IS PLACED IN A SAMPLE REACTOR MODULE AND THIS MODULE IS PAIRED WITH AN ANALYSIS TUBE MODULE, BOTH POSITIONED IN SPECIFIC APERTURES OF A CHEMICAL ANALYSIS ROTARY MODULE. A CHEMICAL ANALYSIS SAMPLE DISSOLVER MODULE TYPICALLY COOPERATIVELY PROVIDES A SCHEDULED SOLVENT VOLUME, DISRUPTS, STIRS AND DISSOLVES THE SAMPLE IN THE SOLVENT, AND MAKES A FILTERED SOLUTION AVAILABLE IN THE REACTOR MODULE. EACH REACTTOR MODULE ACCOMMODATES AN INDIVIDUAL SAMPLE SOLUTION IN THE SEQUENTIAL PROCESSING ON THE ROTARY MODULE. A MULTIPLICITY OF COOPERATIVE LIQUID VOLUME PROBE MEANS ARE CONCENTRICALLY DISPOSED ON A CENTRAL RECIPROCATING ELEVATOR MEANS. THEY PROVIDE, IN

CONJUNCTION WITH A MULTIPLICITY OF CHEMICAL SOLUTION PUMP MEANS, PROGRAMMED INDIVIDUAL VOLUMES OF INDIVIDUAL CHEMICAL SOLUTIONS SUITABLE FOR CHEMICALLY PROCESSING THE SAMPLE SOLUTION IN A SERIALIZED SPECIFIC PAIR OF REACTOR MODULE AND TUBE MODULE. THE SYSTEM FINALLY YIELDS AN ALIQUOT ANALYSIS SOLUTION SAMPLE SUITABLE FOR A DIRECT QUANTITATIVE CHEMICAL ANALYSIS MEASUREMENT, AS BY A SPECTROPHOTOMETER OR THE LIKE.
