Filed: 1958-05-19
Abstract: 856,885. Centrifugal pumps. BELL & GOSSETT CO. May 19, 1958, No. 15961/58. Class 110 (1). A centrifugal pump comprises a priming reservoir 10 having an access aperture closed by a flange 16 which forms one wall of an impeller chamber 17, the other wall being formed by an insertion 26. Some or all of the walls of the insertion 26 may instead be integral with the reservoir 10. The suction passage 12 is upcast to retain liquid in the pump at a level 14 when the pump is stopped. When the pump is started again, a mixture of liquid and air is discharged through diffuser passages formed between vanes 29. The lower diffuser passages discharged directly into the reservoir below the liquid level, while the discharge from the upper diffuser passages is directed into the reservoir by means of an arcuate wall 30 forming an extension of one of the vanes 29. The entrained air separates from the liquid in the reservoir and passes to the pump discharge 11. Airfree liquid enters the impeller chamber 17 through priming ports 43 situated below the liquid surface, and some air-free liquid also returns to the chamber along the bubble-free rear surfaces of the vanes 29. An extension 52 of one of the vanes 29 may be provided, forming a channel 53 in which the liquid level falls more rapidly than the general liquid level on stoppage of the pump, thereby breaking the siphon earlier. Siphoning may be opposed by a check valve (not shown) provided at the inlet 13, the valve being provided with bleed holes so that reverse flow is retarded but not prevented. The priming ports 43 may be above the liquid level, with tubing extending to a point below the liquid level. Alternatively, priming passages can be brought through the surface 37. A plug 46 is provided for the initial filling of the pump.

To compensate for variations in the temperature of a fluid the flow of which is being metered, pulses representing the fluid flow (on conductor 23, (Fig. 1)) after shaping are fed to a gate 32 receiving a reference voltage corresponding to a reference temperature so that negative pulses at the reference voltage and at a rate dependent on the fluid flow are fed to a differential amplifier 37, the amplifier also receiving pulses at the same frequency but at an amplitude dependent on the temperature of the fluid determined by a probe 36. The amplifier output is integrated using an operational amplifier 56 and integrating capacitor 57, subtraction and addition level detectors 41, 42 being operated when the ramp output on conductor 59 reaches predetermined positive or negative levels to operate gates 15, 17, the gates receiving on their other inputs pulses representing fluid flow. Operation of gate 15 results in a pulse being inhibited and operation of gate 17 results in a pulse being added so that the pulse train output at terminal 19 is temperature compensated. After the level detectors are triggered the integrating capacitor is discharged. The gain of amplifier 37 may be adjusted by means of resistor 55 to compensate for different thermal coefficients of expansion of different liquids.

In the voltage regulator disclosed in Speci. fication 742,505 in which the A.C. voltage to be controlled is applied to the heater of a diode Vo to produce at R3 a D.C. control voltage of variable magnitude and negative polarity, an A.C. output signal of varying amplitude and reversible phase is obtained by applying the D.C. signal to both suppressor grids of a pair of variable-mu pentodes VA, V B  and applying an A.C. voltage in opposite phase to the control grids of the valves via transformer T1 and resistors R9 ... R12. The output from transformer T3 is, Fig. 2 (not shown), a variable amplitude A.C. signal of fixed phase. In order to obtain a reversible phase signal, this output is added to the original A.C. voltage phase shifted by R8, C3 so that it is 180 degrees out of phase with the signal from T3. The resultant signal across resistor R7 thus varies from a maximum in one phase sense, through zero to a maximum in the reverse phase sense.
