IPC: F04B19/12
Filed: 1965-12-23
Abstract: 1,098,711. Screw pumps. NAAMLOOZE VENNOOTSCHAP MACHINEFABRIEK SPAANS. Dec. 23, 1966 [Dec. 23, 1965], No.54737/65. Heading F1C. In an Archimedean screw pump comprising a screw (not shown) supported for rotation about an inclined axis, and a part-cylindrical trough 10 extending the full length of the screw for conveying liquid lifted by the screw, the base 27 at least of an upper section of the trough is movably mounted to allow the effective vertical height of the trough to be varied in accordance with the required level of discharge. In the sewage pump shown, the lower part of the trough is of concrete, the upper part being fabricated from sheet steel and projecting from a mounting plate 33 which is bolted to the concrete structure. The hollow base 27 of approximately the final half of the steel upper part of the trough 10 is formed as a float which can slide longitudinally relative to the remainder of the upper part, whereby any change in the level of liquid in the canal into which the pump discharges causes the base 27 to float up or down to produce a corresponding change of the effective height of the trough. For clarity, the base is shown as withdrawn from its operative position in which it overlaps the fixed base of the initial portion of the upper part of the trough 10 with guide rollers 29 engaging guide channels 30. Subsidiary rollers 35 engage the bases of the channels 30. The trough 10 may be constructed wholly of sheet metal and the base 27 may be partly filled with oil to ballast it. Instead of sliding relative to the remainder of the trough, the floating base may be pivoted at its lower end about a horizontal axis. Instead of being formed as a float, the hinged or slidable portion of the trough may be moved by means of cables which are raised or lowered by a reversible electric motor controlled by liquid level sensing probes and limit switches.

Filed: 1971-11-26
Abstract: 1363699 Flowmeter rotation direction determiriation W A WEMYSS 2 Feb 1973 [26 Nov 1971] 55046/71 Heading G4H A flowmeter comprises two responders to rotor position which subtend an angle of less than 180 degrees at the rotation axis, means for counting the responses of either responder and a comparator for determining the direction of rotation from a comparison of the time between response of the first and second responders and the subsequent interval before the first responder responds again. Preferably the subtended angle is between 10 and 30 degrees and the responders are magnetically excited reed switches or inductively or capacitively excited. Rotation of rotor 4 actuates switches 1 and 2 which generate pulse trains having phase difference α. The pulses are shaped by monostables 11 and 12 and applied to set and reset inputs of bi-stable device 10. The antiphase outputs A and B have mark space ratios of ratio α : 360-α and vice versa for anticlockwise rotation as shown in Fig. 1, the pulse trains being shown in Fig. 2. The pulses of either the set or the reset train are counted to indicate the total flow. The direction of flow is determined either by integrating the output waveforms from A and B and determining which is larger or by integrating one of the waveforms and comparing the resulting voltage with the voltage produced by a 50 : 50 mark/space waveform. Separate counters may be used for different directions of flow or one counter with the input applied additively or subtractively according to flow direction.
