Patent EP-0038611-A2 (EP)
Inventor: BILEWSKI FRED
IPC: B01D63/02
Filed: 1979-09-13
Abstract: A hollow filament separatory module comprises a helically wound annular bundle of semi-permeable tubular filaments (22) contained in a pressure resistant enclosure (32, 34, 36, 38). Fluid concentrate to be separated is supplied under pressure through a port (44) to the outsides of the filaments (22) and the separated permeate flows through open ends of the filaments into a collection chamber (71) and thence flows out of a port (50). To separate the pressurised fluid concentrate from the collection chamber (71) the ends of the filaments are embedded in potting compound (66) and sealing rings (58, 60) form seals between the enclosure port (34) and the potting compound (66). The inlet pressure of the fluid is balanced by a pressure between an end plate (38) of the enclosure and a flat face of the potting compound (66). It is essential however for the filaments (22) to have open ends opening into the chamber (71) and to provide this while maintaining a sufficient area of the potting compound (66) in contact with the plate (30) and so, the potting compound has a series of V-shaped slices cut from it to provide the surfaces (78,79), see Figure 2. The sum of the areas (78, 79) projected on the plate (38) is less than 50% of the area of the remaining flatface of the potting compound in contact with the plate (38).

Abstract: Sequence filters to find out positive sequence or negative sequence components of a three phase AC system employ one to three operational amplifiers and a single reactive element to generate the required sequence voltage of a three phase AC power system by producing two line-to-line voltages, phase shifting one of them to bring them into phase and summing the resultant signals. The phase shifting circuit includes a potentiometer, one end of which serves as the imput to the circuit and the other end of which is connected to the inverting input of an operational amplifier. A capacitor is connected between the tap point of the potentiometer and ground an the values of the components are selected so that the tap point of the potentiometer can be positioned to compensate for variations in the capacitive reactance of the capacitor without affecting the magnitude of the phase shifted signal.
