Abstract
Abstract 997,974. Valves. BOWSER Inc. Jan. 30, 1964 [May 6, 1963], No. 4022/64. Heading F2V. [Also in Division B1] A device for dispersing a contaminant in a liquid flow, e.g. water in a liquid fuel, to produce a uniform dispersion for testing purposes (see Figs. 1 and 3, not shown), comprises a conduit 12 discharging through apertures 70 into a conduit 14; a chamber 78 resiliently biased against the liquid flow 82 uncovers a greater number of apertures as the rate of flow increases in order to provide a substantially constant pressure-drop across the device. Specification 993,479 is referred to.

A DEVICE ADAPTED TO EFFECT A SUBSTANTIALLY UNIFORM DISPERSION OF WATER IN A SYSTEM FOR TESTING FOR SUCH CONTAMINANTS, COMPRISING: (A) MEANS HAVING A PLURALITY OF INDIVIDUALLY FORMED OPENINGS WHICH ARE SPACED THEREIN FOR CONVEYING A QUANTITY OF FLUID; (B) FLUID PRESSURE-RESPONSIVE PISTON-VALVE MEANS HAVING ORIFICE CONTROL SURFACES ADAPTED TO COVER AN UNCOVER SAID OPENINGS WHICH ARE CONSTRUCTED TO PROVIDE A CUMULATIVE AREA DEFINING THE EFFECTIVE TOTAL ORIFICE OPENING THROUGH WHICH FLUID IS PASSED FROM SAID CONVEYING MEANS INTO SAID CHAMBER; (C) MEANS FOR BIASING SAID FLUID PRESSURE-RESPONSIVE MEANS IN A DIRECTION WHICH TENDS TO REDUCE THE NUMBER OF UNCOVERED ORIFICES, SAID PRESSURE-RESPONSIVE MEANS BEING MOVABLE TO INCREASE THE NUMBER OF AVAILABLE ORIFICE OPENINGS DEFINING THE EFFECTIVE ORIFICE AREA TO MAINTAIN A SUBSTANTIALLY CONSTANT PRESSURE DIFFERENTIAL REGARDLESS OF THE DEGREE OF FLOW; (D) AND CONTAMINANT MEASURING MEANS FOR RECEIVING THE FLOW OF FLUID AFTER IT HAS PASSED THROUGH SAID ORIFICES TO BECOME SUBSTANTIALLY COMPLETELY DISPERSED IN SAID FLOW.
