Title: Improvements in and relating to pumps
IPC: F04D1/06
Filed: 1964-01-13
Abstract: 999,493. Centrifugal pumps. H. KRAEMER. Jan. 13, 1964 [Jan. 12, 1963], No. 1364/64. . Heading F1C. [Also in Divisions F2 and H2] In a multi-stage rotary pump driven by a gap tube electric motor, the impellers and the armature are arranged at opposed ends of a shaft, and that part of the shaft extending therebetween is supported by a single bearing. A shaft 3, carrying in overhung fashion the pump impellers 5 and the motor armature 6, is mounted at its centre in a bearing 4. The bearing 4 is lubricated and, if necessary, cooled by liquid by-passed from an intermediate or, as shown, the final pump stage, through a screen 13, openings 12, a bore 8 in the shaft 3, and a gap 26 between the motor gap tube 7 and the armature 6 to the motor end of the bearing clearance 17 which extends to the pump inlet chamber. The liquid entering the clearance 17 is clean since any solid particles are centrifugally separated at the outlet end of the gap 26. The liquid not entering the clearance 17 passes through openings 28 to the inlet chamber 18. Alternatively, the by-passed liquid may be returned to an intermediate pump stage. The by-passed liquid cools the motor 2 and, in the gap 26, creates a floating bearing for the shaft 3. The pressure drop in the liquid passing through the gap 26 enables the armature 6 to act as a pressure compensating piston for the pump 1. A case hardened ball 23 contacting a thrust face 21 supports the shaft 3 axially when the pump is stationary or during starting thereof. A hollow screw 15 at the pump end of the shaft 3 may be replaced by one having a different size aperture 16 to adjust the quantity and pressure of the liquid passing to the gap tube 7. The pump may be used as an underwater massage pump, the heat removed from the motor being supplied to the circuit of the massage bath to maintain the liquid temperature therein. Alternatively, the pump may be used in a steam plant to pump and partially heat the condensate.

Abstract: 722,662. Treating gases with liquids. KOPPERS CO., Inc. Jan. 19, 1953, [Jan. 26, 1952.] No. 1508/53. Class 55 (2). A counter-current stage-wise spray washer apparatus comprises a shell 12 with gas inlet and outlet 17, 18, and liquid inlet and outlet 20, 22, and in each stage of gas distribution, scrubbing and outlet chambers 33, 35, 34, with a slotted partition shown as a cylinder 39 between the first two chambers and a ported partition 42 also shown as a cylinder between the second and third through orifices 43, of which nozzles 26 in the outlet chamber direct a fine spray into and across the scrubbing chamber against partition 39, liquid being deflected away from the slots 40 by overlying baffles. In passing through orifices 43 the gas encounters at highest velocity the more closely spaced globules of spray before rising into a de-entrainment space 32 in which, by means of co-axial cylindrical partitions 44, 45, sudden changes in direction of flow are produced. Liquid depositing in this zone descends an overflow pipe 52 to a pool 51 in the scrubbing chamber where it is pumped from a well 48 back to the spray nozzles. Overflow from stage to stage is effected by discharge over weirs 50 provided by the base of the slots 40 onto the floor of the de-entrainment zone below. From the uppermost stage the gas traverses a mist eliminator 30 on its way to the outlet 18.

Abstract: 563,659. Automatic control systems. STANDARD TELEPHONES & CABLES, Ltd., and LEVY, M. M. 'Jan. 29, 1943, No. 1531. [Classes 38 (ii) and 38 (iv)] [Also in Groups XIX and XXXVIII] A member deflected in accordance with an electrical quantity, such as the indicating needle of a measuring instrument, carries a coil or coils 12, 13 adapted to couple electromagnetically two fixed coils 15, 16 as it moves into their vicinity. The fixed coils are preferably screened from one another and one is energized by alternating current so that the other develops an output voltage which becomes a maximum when the movable coils come coaxial with the fixed coils. The output voltage is used to maintain constant a characteristic of the energizing wires and may vary as indicated in Fig. 4; by varying the shape of the coils this curve may be modified. Preferably, a moving coil is wound from aluminium strip on edge so that its self capacity may give the short-circuit a natural frequency to which a valve oscillator energizing one fixed coil may be tuned ; the output coil is preferably tuned to the same frequency. Fig. 3 shows an arrangement in which a valve 23 is coupled with a Hartley oscillating circuit tuned by condenser 24 and the output from coil 16 is tuned by condenser 33. A.C. control voltage may be taken from its terminals or by using a diode 26 or other rectifier a D.C. voltage may be taken at terminals 31, 32. Fig. 5 shows a means whereby the current output of an oscillator V0 may be maintained constant by a thermocouple and meter control unit MCU giving an output voltage at 31, 32 in the manner described which is applied to the grid of a valve VI having an anode resistance R8, whereby variations in current produce amplified variations of the voltage in the grid of a valve V2 loading the oscillator V0. If the thermocouple or a rectifying device shunts the oscillator terminals the voltage may be kept constant ; a voltmeter arrangement may maintain constant load. In these arrangements the operation is such as to stabilize the controlled quantity at a value represented by the point P on the resonance curve shown in Fig. 4. Specification 556,757, [Group XL], is referred to.
