Abstract: 703,381. Well swabs. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. Jan. 25, 1952 [Jan. 29, 1951], No. 2088/52. Class 85 In a well swab assembly the swab rubbers 16, 16a are mounted between abutments 18, 20 on a tubular sleeve 13 positioned about a mandrel 11 so as to slide freely between a coupling 25 and abutment 12 on the latter. The bore of the sleeve is larger than the external diameter of the mandrel so that a passage or passages is or are formed therebetween, said passage or passages being connected to the exterior of the collar 20 by ports 23. In operation the tool is connected by the coupling 25 and weight bar 28 to a wire and is lowered thereby into the well, the frictional engagement of the rubbers causing the sleeve to slide up the mandrel and abut against the surface 26 of coupling 25. Well fluid can pass from below to above the swabs by way of the passage 15 and ports 23. When the tool is drawn upwards the sleeve slides down the mandrel to abut against the abutment 12 and the bevelled mating surfaces 30, 31 seal off the passage 15, so preventing flow of fluid from above to below the tool. In a modified form the ports can be formed in the coupling and the tubular sleeve is formed of a number of non-connected abutting components.

[Also in Division H3] The speed of an electric motor 1 supplied from an A.C. source 3 is controlled by adjustment of the firing angle of a silicon controlled rectifier 5 which is effected by a circuit 13 in response to the magnitude of an A.C. or D.C. input signal at 15. The circuit 13 comprises a unijunction transistor 35 which conducts and triggers the S.C.R. 5 upon attainment of a suitable voltage on capacitor 29, which is charged at a slow rate through resistor 27 and initially at a high rate from the point 41 through the input circuit 15. With little or no input signal the fast charging rate is rapidly cut off by diode 43 becoming reverse biased and the time constant of the slow rate is such that the S.C.R. is triggered at the end of the relevant half cycle, so late that the motor doesn't run. Increasing input voltage at 15, appropriately phased if A.C., charges 29 more rapidly and so advances the firing of S.C.R. 5. The triggering circuit is energized from supply 3 through diode 51 and resistor 49 and is voltage stabilized by Zener diode 21. An arrangement is described (Fig. 3, not shown) whereby two basic circuits are connected to control a split phase motor in either direction according to which circuit receives an input. In this case the motor is energized during alternate half cycles only, but in a further embodiment, using four basic circuits, both half cycles are employed.
