Title: Continuously operating filtering device
Inventor: THISSEN KAREL A
IPC: B01D33/056
Filed: 1993-11-30
Abstract: ABSTRACT    Continuously operating filtering devices are voluminous when accommodated in a casing. The casing serves to maintain a determined pressure round the filter, for instance in view of released gases. It is the objective to keep the volume as small as possible. This is achieved by using plastic as carrier belt. Up to the present rubber carrier belts have been used. These however impose limitations on the diameter of the guide rollers. A limitation of the roller diameter to 25% in comparison to rubber carrier belts is possible with the use of plastic. In addition, plastic has a better resistance to aggressive substances.

Title: Fluid flow control system
Inventor: THOMPSON GARY E
IPC: E03C1/122
Filed: 1992-10-14
Abstract: A system for controlling fluid flow between a first point and a second point on a fluid line is disclosed. The system includes the first valve (50) located at the first point on the fluid line to permit forward fluid flow from the first point to the second point on the fluid line and for closing to prevent such forward fluid flow. The system also includes flow sensors (60-74) for detecting forward fluid flow at the second point and opening the first valve when such forward fluid flow is detected. The flow sensors also close the first valve when fluid flow at the second point stops. The system further includes a second valve (54) located at the second point for opening and closing to control forward fluid flow at the second point. The system prevents forward fluid flow if a break in the fluid line occurs between the first and second points by preventing the first valve from opening. The first valve is prevented from opening since forward fluid flow cannot occur at the second point when the second valve is opened if a depressurizing break in the fluid line has occurred.
