Abstract: 1519978 Borehole logging EXXON PRODUCTION RESEARCH CO 16 Oct 1975 [3 March 1975] 36558/77 Divided out of 1519977 Heading G1N The partial water saturation Sw of a formation in a borehole is determined from the dielectric constant of the formation. The formula C t = F*-1 (CwSw + BQuS<SP>P</SP>w) is employed to calculate the water saturation Sw where C t  is specific conductivity of the shaly sand formation being tested, F* is formation resistivity factor for shaly sand, Cw is specific conductivity of the aqueous saturant, p is shaliness exponent, n is desaturation exponent, B is equivalent conductance of clay exchange cations as a function of Cw at 25C and Qv is cation exchange capacity per unit pore volume. The values of C t , F* and Cw are obtained from routine well logging methods. The dielectric constant of the formation is measured by "deep" dielectric measurements using a logging tool including a pair of vertically spaced bow electrodes and the circuit described in Specification 1519977.   The value of the conductivity parameter BQ V S<SP>p</SP>w is then obtained by comparing the measured dielectric with a correlation relating dielectric to the conductivity parameter. Methods of obtaining the correlation are described.

Title: Automatic screw thread-cutting arrangement for a lathe
IPC: B23Q1/68
Filed: 1956-12-04
Abstract: 814,599. Screw-cutting lathes. JEANNERET, J. L. Dec. 4, 1956 [March 21, 1956], No. 37091/56. Class 83 (3). A screw-thread cutting arrangement for a lathe comprises a support 5<SP>1</SP> clamped to the normal tool-rest, a tool-holding slide 1, Fig. 4, and an auxiliary slide 5, these slides being moved along the support perpendicular to the thread-cutting axis by a control handle 8 to space the slides apart by a toggle mechanism against the action of springs. The depth of cut of the tool 2 is determined by an abutment 17 on the slide 5 engaging an automatically indexible member 6 having a number of stop faces at varying distances from its axis. Threadcutting is performed with the parts in the position shown in Fig. 7. At the end of the cutting stroke a fixed stop 10, Fig. 4, strikes the end 37 of a bell crank 9 pivoted on the slide 5. The opposite end of this lever has a latch 30, Fig. 7, which releases another lever 26 connected to the spindle carrying the handle 9. The latter is rotated anticlockwise by a spring plunger 33, and a roller 25 on lever 26 is thus brought out of engagement with a ledge 27 on the slide 1. This slide is then free to be retracted by a spring 13 to relieve the tool from the work and bring the slide against an abutment 12 on the support. The slide 5 is also now free to move forwardly to the same abutment 12, impelled by a spring 15 which is weaker than the spring 13. To re-set the tool with an increased cut ready for a fresh cutting action, the handle 8 is first pulled back in an anticlockwise direction to index the stop 6 (see below) and then rotated to the full extent in a clockwise direction. The latter movement forces the slide 5 back against the stop 6 and then, with the roller 25 engaging the ledge 27 on the tool slide 1, this is forced forward to a new depth-of-cut position. The latch 30 finally engages the end of lever 26 to hold the parts in their set position. A lever 43, Fig. 10, on the lower end of the spindle 40 of lever 8, when the latter is moved anticlockwise, moves a ratchet mechanism 45, 46, 57 to index the stop 6. The ratchet may be released to return the stop to the " start by a push-button 54.

Title: Hydrostatic torque-measuring device
IPC: G01L3/14
Filed: 1957-11-29
Abstract: 879,478. Measuring torque. WIGGERMANN, G., and REINERS, W. Nov. 29, 1957 [Dec. 3, 1956], No. 37272/57. Class 106 (2). A torque-measuring coupling insertable between driving and driven elements 1, 5 comprises a rotor 3, a housing 4 rotatable about the rotor on bearing races 7, the housing and the rotor both being formed with radial claws 8, 9, arranged alternately to form displacement spaces - 10a, 10b, to which oil under pressure is continuously supplied by a transmitter 14 in which the rotor 3 is journalled, the housing 4 having a neck portion 21 which freely surrounds the rotor, and the transmitter being sealed at its ends by oil collector covers 17a, 17b, the cover 17b being in communication with the spaces 10a, 10b through the bearing races 7 and the neck portion 21. As shown, the claw rings 3, 4 are fixed to the driving shaft 1 and driven shaft 5 respectively. Oil is supplied under pressure, through the axis 26 of shaft 1 and radial bores 28 in the rotor 3, to the displacement spaces 10a, 10b, entering these through recesses 30a, 30b in the ring 4. From the spaces 10a, 10b, the oil flows by control bores 31a, 31b to an annular recess 32 in the rotor 3 and thence through the races 7 and the neck portion 21 to a drain. The passages are so constructed that the centrifugal forces acting on the oil being supplied and discharged cancel, and so the indication given by a pressure gauge connected to the supply is unaffected by the speed of revolution of the shaft 1. If there is no torque, the relative positions of the members 3, 4 are as shown, but if a torque is transmitted, then, for example, spaces 10a tend to close and spaces 10b tend to open. As this happens, bores 28 move out of alignment with recesses 30a and further into agreement with recesses 30b. At the same time, control bores 31b are closed by the claws 8 and other control bores 31a open further to the spaces 10a. By these means, pressure oil is supplied only to the spaces 10b, and the spaces 10a are virtually drained. The pressure indicated on the gauge is thus a measure of the torque. If the pressure should tend to increase beyond the maximum allowed for the gauge, an excess pressure valve on the pump relieves the pressure and the members 3, 4 lock together for direct drive, the impact being cushioned, however, by the oil in the spaces 10b. The oil may be supplied from the lubricating circuit of a driving engine. In an alternative embodiment, the bores 28 may open into the spaces 10a, 10b by transverse bores, perpendicular to the plane of the Figure, the recesses 30a, 30b being machined in cover plates 5, 6.
