Title: Improvements in or relating to speed-reduction gearing
IPC: F16H15/52
Filed: 1950-12-14
Abstract: 696,145. Variable-speed gearing. KENYON & SONS, Ltd., W., and GROSSMAN, F. Dec. 3, 1951 [Dec. 14, 1950], No. 30496/50. Class 80 (ii). A planetary friction roller 28 is eccentrically carried by a driving shaft 14 to roll around the inside of a fixed ring 42, the resulting rotation in a reversed direction being transmitted to a driven shaft 15 through an Oldham type coupling 35, 38, 41. A speed reduction inversely proportional to the difference between the effective diameters of the roller 28 and ring 42 is obtained, and to effect a variation in the speed the contacting surfaces of the roller and the ring are made frusto-conical and the ring 42 is adjustable axially on guide rods 45 by means of a screw 47 and handwheel 48 to vary the position at which it contacts with the roller. To allow for this variation in effective diameter of the ring 42 the eccentric mounting of roller 28 on the shaft 14 comprises an inner eccentric 18. fixed on the shaft and an outer eccentric 20 of equal throw biased relatively thereto by a spring 26 to give a maximum throw of the combined accentric. The maximum difference between the effective diameters of the roller and fixed ring must be less than twice the maximum throw of the compound eccentric in order.that frictional contact is always maintained, the difference in diameter down to zero, at which no speed is transmitted, being accommodated by the two eccentrics moving out-of-phase against the spring pressure until the compound eccentricity is zero. Alternative spring arrangements for effecting the bias between the two eccentrics may be provided and a splined connection acted upon by an axially acting spring may be utilised. The axial adjustment of ring 42 to vary the reduction ratio may be effected automatically in response to, for example, the torque resistance on the driven shaft 15.

Abstract: 1520295 Well logging SCHLUMBERGER Ltd 22 July 1975 [22 July 1974] 30522/75 Heading G1N In order to distinguish between permeable and impermeable formations in a well bore by determining the presence of mud cake which forms on the bore wall opposite permeable formations a well logging tool of the type emitting a main and  auxiliary current into the formations is passed down the borehole, the main current flowing primarily in the formations surrounding the borehole and the auxiliary current being confined primarily to the borehole and immediately surrounding formation; producing first and second signals related respectively to the main and auxiliary currents and producing first and second output parameters providing jointly an indication of permeable zones, the first varying as a function of the second signal and the second as a function of the first and second signals. As described the logging tool is a conventional spherically focused pad mounted electrode tool including a plurality of potential monitoring electrodes as well as a current emitting electrode and wherein one of the main or auxiliary currents is adjusted in response to the measured potentials to establish a given potential distribution in at least a portion of the borehole so that the auxiliary current tends to force the main current into the formation. The outputs of the tool representative of the tool representative of the conductivity traversed by the main current i.e. reciprocal of the deep resistivity Rd of the formation and the conductivity traversed by the auxiliary current i.e. reciprocal of shallow resistivity Rs are fed to a processing unit on the surface which may be an analogue circuit or a suitably programmed digital computer for obtaining the two parameters. Three circuits are described which act on the first and second signals which vary as respective functions of Rm/Rs and Rm/Rd where Rm is the resistivity of the drilling mud filling the borehole, in order to obtain the parameters R 1  *, R 2  * from the equations following. Circuit 1. R 1 * = K 1 Rs/Rm + K 2  R 2  * = (K 3 Rm/Rd + K 4 # 2  *Rm/Rs + K 5 )<SP>-1</SP> where # 2 * = (K 1  + K 2 Rm/Rs)<SP>-1</SP> and K 1 , K 2 , K 3 , K4 and K 5  are constants. Circuit 2:- R 1 * = K 6 Rs/Rm { 1 + K 7 (K 8 Rm/Rd + K 9 Rm/Rs)<SP>-1</SP> } R 2 * = (K 8 R<SP>m</SP>/Rd + K 9 Rm/Rs)<SP>-1</SP> -K 10  where K6 to K 10  are constants; and circuit 3:-  R 1 * = Rs/Rm (K 11  + K 12 Rs/Rd)<SP>-1</SP> R2* = (K 13 Rm/Rd + K 14 Rm/Rs + K 15 )<SP>-1</SP> where K 11  to K 15  are constants. The values of the resistivity parameters R 1 *, R 2 * and the ratio R 2 */R 1 * formed in a dividing circuit are then used to facilitate the location of hydrocarbon. Thus when R 2 * exceeds R 1 * or R 2 */R 1 * exceeds one there must be mud cake present on the borehole wall and the formation is permeable.
