Title: Monitoring drilling mud composition using ion selective electrodes
Inventor: JASINSKI RAYMOND
IPC: E21B47/10
Filed: 1989-11-08
Abstract: ABSTRACT                    MONITORING DRILLING MUD COMPOSITION    USING ION SELECTIVE ELECTRODES   In  the  rotary  drilling of oil wells a drilling mud is used both to transport  the  cuttings  up  to the  surface and to impose an hydrostatic pressure  on  the  walls of the borehole.  For these functions the mud must for  example  have  an  acceptable  density and viscosity.  It is therefore important to monitor  the  characteristics  of  the mud, and to keep them within  certain  limits.    Only  recently,  however, has drilling practice recognised the importance of monitoring the mud's ionic composition. The  technique  proposed  involves  the  use  of an ion selective/ion selective  electrode  pair  to  measure  in  the  mud  the potential of the selected   ion  pair,   and   so   allow  a  determination  of  one  ion's concentration.   Thus, it is a method in which, using a selective/selective electrode  pair, there is determined the potrntial difference generated by, and  thus  the  concentration of, the two ions in the mud - and knowing the concentration  of  the  second  ion there may be computed that of the other (chosen) one.

Title: Variable camshaft timing for internal combustion engine
Inventor: BUTTERFIELD ROGER P
IPC: F02B75/02
Filed: 1990-10-10
Abstract: A variable camshaft timing arrangement for an internal combustion engine in which a camshaft, for example, an intake valve operating camshaft in a dual camshaft engine, is advanced or retarded in its position relative to the crankshaft and to the exhaust valve operating camshaft in reaction to torque pulsations in such intake valve operating camshaft.      The camshaft has a sprocket oscillatingly mounted thereon, or on the other camshaft of a dual camshaft system. The camshaft carrying the oscillatingly mounted sprocket also has a bracket or another sprocket keyed thereto, and the bracket or other sprocket is chain driven by the rotation of the crankshaft. A pair of single acting hydraulic cylinders interconnect the oscillating sprocket and the bracket or other sprocket, with the piston ends of the cylinders pivotably attached to the oscillating sprocket and with the body ends of the cylinders pivotably attached to the other sprocket or bracket. The cylinders act in opposite directions and are hydraulically interconnected so that one extends as the other retracts and vice versa. The hydraulic system includes a control valve which is controlled by an engine controller to selectively permit one of the cylinders to extend, and the other to retract, in reaction to torque pulsations in the camshaft which is being advanced or retarded to provide desired engine operating characteristics. The camshaft which is being advanced or retarded can either be the camshaft which carries the oscillatingly mounted sprocket, or, in a dual camshaft system, it can be the other camshaft or both camshafts. In an engine having cam followers of the friction type, the unidirectionally acting torque on the camshaft which results from the friction between the camshaft and the followers can be offset by providing resilient means to act on one of the opposed cylinders to introduce a countertorque into the camshaft which is oppositely directed to the frictional torque.
